Profields Table CSV Importer / Exporter

Recommended Posts

This module adds CSV import and export functionality to Profields Table fields on both the admin and front-end.

http://modules.processwire.com/modules/table-csv-import-export/
https://github.com/adrianbj/TableCsvImportExport
 
Access to the admin import/export for non-superusers is controlled by two automatically created permissions:

table-csv-import and table-csv-export

Another permission (table-csv-import-overwrite) allows you to control access to the overwrite option when importing.
 
The overwrite option is also controlled at the field level. Go to the table field's Input tab and check the new "Allow overwrite option" if you want this enabled at all for the specific field.

Please consider limiting import overwrite option to trusted roles as you could do a lot of damage very quickly with the overwrite option :)

Front-end export of a table field to CSV can be achieved with the exportCsv() method:

// export as CSV if csv_export=1 is in url
if($input->get->csv_export==1){
   $modules->get('ProcessTableCsvExport'); // load module
   // delimiter, enclosure, file extension, multiple fields separator, names in first row
   $page->fields->tablefield->exportCsv('tab', '"', 'tsv', '|', true); 
}
// display content of template with link to same page with appended csv_export=1
else{
   include("./head.inc");

   echo $page->tablefield->render(); //render table - not necessary for export - just displaying the table
   echo "<a href='./?csv_export=1'>Export Table as CSV</a>"; //link to initiate export

   include("./foot.inc");
}

 
Front-end import can be achieved with the importCsv() method:

$modules->get('TableCsvImportExport'); // load module
// data, delimiter, enclosure, convert decimals, ignore first row, multiple fields separator, append or overwrite
$page->fields->tablefield->importCsv($csvData, ';', '"', true, false, '|', 'append');

Please let me know if you have any problems, or suggestions for improvements.

Enjoy!

I love what you've done.

 

I could imagine you can add an extra data cleaner for the importer with the help of json_encode.

Forget this, to much much my own module in my mind.

I was confused by that which is why I hadn't commented yet - I was trying to let it sink in to see if I could get what you meant :)

I should probably do a little more cleaning of the CSV for trailing commas, extra spaces, and the like - it's on my list.

Small update committed for finer control over the overwrite option when importing.

The new table-csv-import-overwrite permission allows you to control access to the overwrite option when importing. If a user doesn't have this permission, they won't have the option to choose overwrite.
 
The overwrite option is also controlled at the field level. Go to the table field's Input tab and check the new "Allow overwrite option" if you want this enabled at all for the specific field. So if overwrite is not enabled for each particular table field, it doesn't matter what permission the user has, no-one will have access to it.

Awesome module Adrian thanks for sharing. I am getting some strange behavior though. I have two different table field types assigned to one template. When I try uploading a csv I get the following error message. "That is not an allowed file extension for a CSV import. Try again with a .csv, .tsv, or .txt file". My file is indeed a csv.

I have tried both tab and comma separated columns.  If "ignore first row" is checked, it will not import anything. If it is unchecked, it will import only one row. 

Also, if I paste the csv data it imports it fine into the desired columns and table, but also imports the data into the other table field assigned to that template. The two table field types have different names and a different amounts of columns. Any suggestions or tips is appreciated. I will be glad to pm you the csv I am using if you so wish. Thanks in advance.

Hi RJay - wow, that doesn't sound good :)

Yes, please PM me the file. Also, does the same CSV file work on a template with only one Table field?

Hi Adrain, 

I removed one table field from the template and that is when I was able to get it to import the one row after I unchecked "ignore first row" however, I still received the same error message, but it did import the one row. It sound like something is wrong with my csv but I cant see where.  I think there may be a separate issue with it importing into both field types. I am sending you the csv file now. Thanks for taking the time to look at it.

Thanks @RJay - I think I have managed to fix all those issues - I hadn't tested with multiple Table fields on the one page. Please check the latest version and let me know how it goes for you.

PS There was nothing wrong with your CSV file.

Hi Adrian, 

Thanks for such a quick response time. Premium service there :). After applying your updates, I was able to paste the csv data in and it was applied to the proper table, ignoring the other.

However, when trying to import the csv file I still get the message "Session: That is not an allowed file extension for a CSV import. Try again with a .csv, .tsv, or .txt file"

I tried this on both local and development servers just in case it was a permission issue. I then tried removing one of the tables, once I did that, I still received the message, but it did import the first row of the csv file. I am going to try maybe a text file and then just redoing the fields and go from there. I'll let you know what my results are.

*Update

Uploading a txt file works perfectly. Not sure why it does not like the csv files.

However, when trying to import the csv file I still get the message "Session: That is not an allowed file extension for a CSV import. Try again with a .csv, .tsv, or .txt file"

I am thinking it must be my mimetype checks. Can you please try replacing:

if(($csv_file_extension == 'csv' || $csv_file_extension == 'txt' || $csv_file_extension == 'tsv') &&
    ($csv_type == 'text/plain' || $csv_type == 'text/tab-separated-values' || $csv_type == 'text/csv')){
    $this->session->{$fieldName . '_csv_data'} = file_get_contents($_FILES[$csv_filename]["tmp_name"]);
}
 

with:

if($csv_file_extension == 'csv' || $csv_file_extension == 'txt' || $csv_file_extension == 'tsv'){
    $this->session->{$fieldName . '_csv_data'} = file_get_contents($_FILES[$csv_filename]["tmp_name"]);
}

and see if that allows the csv upload to work.

Great to hear. I have committed another update that removes those checks - they really aren't very useful anyways as they can be manipulated in the browser and aren't always provided (hence the errors you were getting).

Can you please confirm that all the other multiple Table field and issues with only one row importing are also now solved?

Thanks for your help in getting this all fixed.

Hi Adrian,

This is a jolly helpful module, thanks for developing it.

I ran into a problem when using it on a page where the table field is contained within a repeater on the page's template.

The set up is as follows:

The page template has the following fields:
  • Title
  • Programmes
Programmes is a repeater field containing two fields:
  • Year
  • Programme
The Year field is an integer field
The Programme field is the table field
 
The error occurs on page save and is reported as follows:
 
Notice: Trying to get property of non-object in [my_path_to]/site/modules/TableCsvImportExport/TableCsvImportExport.module on line 263

Warning: Invalid argument supplied for foreach() in [my_path_to]/site/modules/TableCsvImportExport/TableCsvImportExport.module on line 263

Fatal error: Call to a member function makeBlankItem() on a non-object in [my_path_to]/site/modules/TableCsvImportExport/TableCsvImportExport.module on line 277
Error: Call to a member function makeBlankItem() on a non-object (line 277 of [my_path_to]/site/modules/TableCsvImportExport/TableCsvImportExport.module) 
This error message was shown because site is in debug mode ($config->debug = true; in /site/config.php). Error has been logged.

By reworking the template to include only Title and Programme fields (i.e. a single table, no repeater) the problem goes away.

I can work with that but wondered, since one of the posts above deals with a similar/related use case, if you can help at all.

Many thanks,

Nic

@sgt.blikey - I am glad you like it. I have put together a fix for supporting repeaters - please let me know if it works for you as expected. If anyone sees any issues with normal Table fields (not in repeaters), with this new version, please let me know!

Even though I just added support for repeaters, I want to make sure you have you read this thread: https://processwire.com/talk/topic/8832-error-in-complex-form/ - it is in the Profields support board, but I am assuming you have access. In particular read the post by Ryan where he says that Tables in Repeaters are not officially supported, although he does say that if they were working and now aren't, he'd consider investigating. 

Mostly just wanted to warn you that maybe you will run into other issues with this approach.

Have you considered switching to PageTables or even simple child pages and putting your Table field in those?

@adrian

I (don't) think I had seen the thread you linked to. I guess table fields in repeaters is adding a layer of complexity that need not be there and it would be sensible to follow the PageTables/child pages route.

I'll have a go with your updated module and let you know how that goes but will probably implement as PageTables/child pages.

Many thanks for acting so promptly.

Nic

(oops, hadn't actually seen that thread!)

@adrian I haven't had an opportunity to use the module within a repeater. I don't think I will do following your guidance. Thanks for your help.

Hi everyone,

I have just added support for single and multiple page-reference fields and multiple options - requires PW 2.6.4 and Table 7-beta that Ryan released last week.

  • Export converts page IDs to the title of the page.
  • Import looks up the titles and populates the table with the IDs of the matching pages.

Please let me know if you have any problems with this new version.

A few more tweaks - you can now specify the separator when importing and exporting tables with the new multi-value fields. Also a couple of bug fixes and a speed improvement when importing.

Hi Adrian,

I think there's a problem when using your module with any other code or modules that use fgets() or file() - such as Horst's WireQueueTextfile module (and possibly others.) I've just spent a couple of hours tracking this down over IRC with a client.

The init() routine of your module sets PHPs auto_detect_line_endings flag to true - which can have un-intended consequences on other code run after your module initialises. In my client's case, they are using WireQueue with the textfile storage and it was throwing up errors, with your module installed, while unserialising a line pulled from the queue file using fgets() at the end of the getItem() method that pulls an item from the Wire Queue.

Commenting out the following in TableCsvImportExport.module;

ini_set('auto_detect_line_endings', true);

fixed things for us.

I understand the attraction of making the exported/imported files cross-platform compatible, but I think your module has other options open rather than changing the PHP setting during the init() routine. Perhaps, at the start of the import routine, you could read the initial state of that flag, then ini_set() it to true while you do the import and finally restore it to the initial setting on exit from your routine?

Thanks for your great modules and for considering this request!

      First a note about my other modules...
      I have three existing modules that are similar in that they allow restrictions to be placed on repeating inputfields: Limit Repeater, Limit PageTable, Limit Table
      Restrict Repeater Matrix takes a different approach to the module configuration from those other modules. The module settings for Restrict Repeater Matrix are applied in the field settings rather in a module config screen. I think this new approach is better, but it means that it isn't practical to create different settings for different roles via the admin interface. Instead the module has a hookable method, allowing roles to be targeted and other advanced usages to be achieved via a hook. The result is that the module is more flexible.
      I intend to transition my other modules to the same approach over the coming weeks, but because this will result in breaking changes I will be releasing the updated modules under new names ("Restrict Repeater", etc) to avoid users upgrading via the Upgrades module without full awareness of the changes. The old modules will be marked as deprecated.
      Restrict Repeater Matrix
      A module for ProcessWire CMS/CMF. Allows restrictions and limits to be placed on Repeater Matrix fields. Requires ProcessWire >= v3.0.0 and FieldtypeRepeaterMatrix >= v0.0.5.
      For any matrix type in a Repeater Matrix field you have the option to:
      Disable settings for items (cannot change matrix type) Prevent drag-sorting of items Prevent cloning of items Prevent toggling of the published state of items Prevent trashing of items Limit the number of items that may be added to the inputfield. When the limit is reached the "Add new" button for the matrix type will be removed and the matrix type will not be available for selection in the "Type" dropdown of other matrix items. Please note that restrictions and limits are applied with CSS/JS so should not be considered tamper-proof.
      Usage
      Install the Restrict Repeater Matrix module.
      For each matrix type created in the Repeater Matrix field settings, a "Restrictions" fieldset is added at the bottom of the matrix type settings:

      For newly added matrix types, the settings must be saved first in order for the Restrictions fieldset to appear. Set restrictions for each matrix type as needed. A limit of zero means that no items of that matrix type may be added to the inputfield.
      Setting restrictions via a hook
      Besides setting restrictions in the field settings, you can also apply or modify restrictions by hookingRestrictRepeaterMatrix::checkRestrictions. This allows for more focused restrictions, for example, applying restrictions depending on the template of the page being edited or depending on the role of the user.
      The checkRestrictions() method receives the following arguments:
      $field This Repeater Matrix field $inputfield This Repeater Matrix inputfield $matrix_types An array of matrix types for this field. Each key is the matrix type name and the value is the matrix type integer. $page The page that is open in ProcessPageEdit The method returns a multi-dimensional array of matrix types and restrictions for each of those types. An example of a returned array:

      Example hooks
      Prevent the matrix type "images_block" from being added to "my_matrix_field" in a page with the "basic-page" template:
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $page = $event->arguments('page'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && $page->template->name === 'basic-page') { $type_restrictions['images_block']['limit'] = 0; } $event->return = $type_restrictions; }); Prevent non-superusers from trashing any Repeater Matrix items in "my_matrix_field":
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && !$this->user->isSuperuser()) { foreach($type_restrictions as $key => $value) { $type_restrictions[$key]['notrash'] = true; } } $event->return = $type_restrictions; }); http://modules.processwire.com/modules/restrict-repeater-matrix/

      Here's a little text formatter module that redirects all external links found in a textarea (e.g. for hit counting) to a given URL.
      TextformatterExternalRedirect
      GitHub repo
      As TextFormatters do, this module modifies the contents of the textarea (HTML) at rendering time. It prepends the given URL to the link address for external links (http and https), optionally makes sure that the link is opened in a new window and allows you to add css classes to such links.
      All options can be configured in the module's configuration settings.
      Usage:
      Download the zip archive and extract it to site/modules, the rename the top folder to TextformatterExternalRedirect Go to the backend and select "Modules" -> "Refresh", then click "Install" for "External Link Redirect" Click "Settings" and configure the module
      Go into the field configuration for the field(s) you want this formatter to apply to and add it from the dropdown
      Done, now any external links in the configured fields will have the configured settings applied Feel free to leave feedback and post and questions you have here.

      Hey folks!
      Took a couple of late nights, but managed to turn this old gist of mine into a proper module. The name is SearchEngine, and currently it provides support for indexing page contents (into a hidden textarea field created automatically), and also includes a helper feature ("Finder") for querying said contents. No fancy features like stemming here yet, but something along those lines might be added later if it seems useful (and if I find a decent implementation to integrate).
      Though the API and selector engine make it really easy to create site search pages, I pretty much always end up duplicating the same features from site to site. Also – since it takes a bit of extra time – it's tempting to skip over some accessibility related things, and leave features like text highlighting out. Overall I think it makes sense to bundle all that into a module, which can then be reused over and over again 🙂
      Note: markup generation is not yet built into the module, which is why the examples below use PageArray::render() method to produce a simple list of results. This will be added later on, as a part of the same module or a separate Markup module. There's also no fancy JS API or anything like that (yet).
      This is an early release, so be kind – I got the find feature working last night (or perhaps this morning), and some final tweaks and updates were made just an hour ago 😅
      GitHub repository: https://github.com/teppokoivula/SearchEngine Modules directory: https://modules.processwire.com/modules/search-engine/ Demo: https://wireframe-framework.com/search/ Usage
      Install SearchEngine module. Note: the module will automatically create an index field install time, so be sure to define a custom field (via site config) before installation if you don't want it to be called "search_index". You can change the field name later as well, but you'll have to update the "index_field" option in site config or module settings (in Admin) after renaming it.
      Add the site search index field to templates you want to make searchable. Use selectors to query values in site search index. Note: you can use any operator for your selectors, you will likely find the '=' and '%=' operators most useful here. You can read more about selector operators from ProcessWire's documentation.
      Options
      By default the module will create a search index field called 'search_index' and store values from Page fields title, headline, summary, and body to said index field when a page is saved. You can modify this behaviour (field name and/or indexed page fields) either via the Module config screen in the PocessWire Admin, or by defining $config->SearchEngine array in your site config file or other applicable location:
      $config->SearchEngine = [ 'index_field' => 'search_index', 'indexed_fields' => [ 'title', 'headline', 'summary', 'body', ], 'prefixes' => [ 'link' => 'link:', ], 'find_args' => [ 'limit' => 25, 'sort' => 'sort', 'operator' => '%=', 'query_param' => null, 'selector_extra' => '', ], ]; You can access the search index field just like any other ProcessWire field with selectors:
      if ($q = $sanitizer->selectorValue($input->get->q)) { $results = $pages->find('search_index%=' . $query_string . ', limit=25'); echo $results->render(); echo $results->renderPager(); } Alternatively you can delegate the find operation to the SearchEngine module as well:
      $query = $modules->get('SearchEngine')->find($input->get->q); echo $query->resultsString; // alias for $query->results->render() echo $query->pager; // alias for $query->results->renderPager() Requirements
      ProcessWire >= 3.0.112 PHP >= 7.1.0 Note: later versions of the module may require Composer, or alternatively some additional features may require installing via Composer. This is still under consideration – so far there's nothing here that would really depend on it, but advanced features like stemming most likely would.
      Installing
      It's the usual thing: download or clone the SearchEngine directory into your /site/modules/ directory and install via Admin. Alternatively you can install SearchEngine with Composer by executing composer require teppokoivula/search-engine in your site directory.

      MarkupMenu is a markup module for generating menu trees. When provided a root page as a starting point, it generates a navigation tree (by default as a HTML "<ul>" element wrapped by a "<nav>" element) from that point onwards. If you've also provided it with current (active) page, the menu will be rendered accordingly, with current item highlighted and items rendered up to that item and its children (unless you disable the "collapsed" option, in which case the full page tree will be rendered instead).
      Modules directory: https://modules.processwire.com/modules/markup-menu/ GitHub repository: https://github.com/teppokoivula/MarkupMenu Usage
      As a markup module, MarkupMenu is intended for front-end use, but you can of course use it in a module as well. Typically you'll only need the render() method, which takes an array of options as its only argument:
      echo $modules->get('MarkupMenu')->render([ 'root_page' => $pages->get(1), 'current_page' => $page, ]); Note: if you omit root_page, site root page is used by default. If you omit current_page, the menu will be rendered, but current (active) page won't be highlighted etc.
      A slightly more complex example, based on what I'm using on one of my own sites to render a (single-level) top menu:
      echo $modules->get('MarkupMenu')->render([ 'current_page' => $page, 'templates' => [ 'nav' => '<nav class="{classes} menu--{menu_class_modifier}" aria-label="{aria_label}">%s</nav>', 'item_current' => '<a class="menu__item menu__item--current" href="{item.url}" tabindex="0" aria-label="Current page: {item.title}">{item.title}</a>', ], 'placeholders' => [ 'menu_class_modifier' => 'top', 'aria_label' => 'Main navigation', ], 'include' => [ 'root_page' => true, ], 'exclude' => [ 'level_greater_than' => 1, ], ]); Note: some things you see above may not be entirely sensible, such as the use of {menu_class_modifier} and {aria_label} placeholders. On the actual site the "nav" template is defined in site config, so I can define just these parts on a case-by-case basis while actual nav markup is maintained in one place.
      Please check out the README file for available render options. I'd very much prefer not to keep this list up to date in multiple places. Basically there are settings for defining "templates" for different parts of the menu (list, item, etc.), include array for defining rules for including in the menu and exclude array for the opposite effect, classes and placeholders arrays for overriding default classes and injecting custom placeholders, etc. 🙂
      MarkupMenu vs. MarkupSimpleNavigation
      TL;DR: this is another take on the same concept. There are many similarities, but also some differences – especially when it comes to the supported options and syntax. If you're currently using MarkupSimpleNavigation then there's probably no reason to switch over.
      I'd be surprised if someone didn't draw lines between this module and Soma's awesome MarkupSimpleNavigation. Simply put I've been using MSN (...) for years, and it's been great – but there are some issues with it, particularly in the markup generation area, and it also does some things in a way that doesn't quite work for me – the xtemplates thing being one of these. In some ways less about features, and more about style, I guess 🙂
      Anyhow, in MarkupMenu I've tried to correct those little hiccups, modernise the default markup, and allow for more flexibility with placeholder variables and additional / different options. MarkupMenu was built for ProcessWire 3.0.112+ and with PHP 7.1+ in mind, it's installable with Composer, and I have a few additional ideas (such as conditional placeholders) still on my todo list.
      One more small(ish) difference is that MarkupMenu supports overriding default options via $config->MarkupMenu. I find myself redefining the default markup for every site, which until now meant that each site had a wrapper function for MarkupSimpleNavigation (to avoid code / config repetition), and this way I've been able to leave that out 🙂
      Requirements
      ProcessWire >= 3.0.112 PHP >= 7.1.0 If you're working on an earlier version of ProcessWire or PHP, use MarkupSimpleNavigation instead.

      Hey folks!
      I'm happy to finally introduce a project I've been working on for quite a while now: it's called Wireframe, and it is an output framework for ProcessWire.
      Note that I'm posting this in the module development area, maily because this project is still in rather early stage. I've built a couple of sites with it myself, and parts of the codebase have been powering some pretty big and complex sites for many years now, but this should still be considered a soft launch 🙂
      --
      Long story short, Wireframe is a module that provides the "backbone" for building sites (and apps) with ProcessWire using an MVC (or perhaps MVVM – one of those three or four letter abbreviations anyway) inspired methodology. You could say that it's an output strategy, but I prefer the term "output framework" since in my mind the word "strategy" means something less tangible. A way of doing things, rather than a tool that actually does things.
      Wireframe (the module) provides a basic implementation for some familiar MVC concepts, such as Controllers and a View layer – the latter of which consists of layouts, partials, and template-specific views. There's no "model" layer, since in this context ProcessWire is the model. As a module Wireframe is actually quite simple – not even nearly the biggest one I've built – but there's still quite a bit of stuff to "get", so I've put together a demo & documentation site for it at https://wireframe-framework.com/.
      In addition to the core module, I'm also working on a couple of site profiles based on it. My current idea is actually to keep the module very light-weight, and implement most of the "opinionated" stuff in site profiles and/or companion modules. For an example MarkupMenu (which I released a while ago) was developed as one of those "companion modules" when I needed a menu module to use on the site profiles.
      Currently there are two public site profiles based on Wireframe:
      site-wireframe-docs is the demo&docs site mentioned above, just with placeholder content replaced with placeholder content. It's not a particularly complex site, but I believe it's still a pretty nice way to dig into the Wireframe module. site-wireframe-boilerplate is a boilerplate (or starter) site profile based on the docs site. This is still very much a work in progress, but essentially I'm trying to build a flexible yet full-featured starter profile you can just grab and start building upon. There will be a proper build process for resources, it will include most of the basic features one tends to need from site to site, etc. --
      Requirements and getting started:
      Wireframe can be installed just like any ProcessWire module. Just clone or download it to your site/modules/ directory and install. It doesn't, though, do a whole lot of stuff on itself – please check out the documentation site for a step-by-step guide on setting up the directory structure, adding the "bootstrap file", etc. You may find it easier to install one of the site profiles mentioned above, but note that this process involves the use of Composer. In the case of the site profiles you can install ProcessWire as usual and download or clone the site profile directory into your setup, but after that you should run "composer install" to get all the dependencies – including the Wireframe module – in place. Hard requirements for Wireframe are ProcessWire 3.0.112 and PHP 7.1+. The codebase is authored with current PHP versions in mind, and while running it on 7.0 may be possible, anything below that definitely won't work. A feature I added just today to the Wireframe module is that in case ProcessWire has write access to your site/templates/ directory, you can use the module settings screen to create the expected directories automatically. Currently that's all, and the module won't – for an example – create Controllers or layouts for you, so you should check out the site profiles for examples on these. (I'm probably going to include some additional helper features in the near future.)

      This project is loosely based on an earlier project called pw-mvc, i.e. the main concepts (such as Controllers and the View layer) are very similar. That being said, Wireframe is a major upgrade in terms of both functionality and architecture: namespaces and autoloader support are now baked in, the codebase requires PHP 7, Controllers are classes extending \Wireframe\Controller (instead of regular "flat" PHP files), implementation based on a module instead of a collection of drop-in files, etc.
      While Wireframe is indeed still in a relatively early stage (0.3.0 was launched today, in case version numbers matter) for the most part I'm happy with the way it works, and likely won't change it too drastically anytime soon – so feel free to give it a try, and if you do, please let me know how it went. I will continue building upon this project, and I am also constantly working on various side projects, such as the site profiles and a few unannounced helper modules.
      I should probably add that while Wireframe is not hard to use, it is more geared towards those interested in "software development" type methodology. With future updates to the module, the site profiles, and the docs I hope to lower the learning curve, but certain level of "developer focus" will remain. Although of course the optimal outcome would be if I could use this project to lure more folks towards that end of the spectrum... 🙂
