Module
Pages2Pdf

228 posts in this topic

Hi,

After reading this thread, I decided to make a module that helps generating PDF files of ProcessWire pages.

GitHub: https://github.com/wanze/Pages2Pdf

Modules Directory: http://modules.processwire.com/modules/pages2-pdf/

This module uses the mPDF library to generate the PDF files. It has fully UTF-8 and basic HTML/CSS support for rendering the PDF files.

The output is customizable with ProcessWire templates. 

Example

I've enabled generating PDF files for the skyscraper template of ryans Skyscrapers-profile with a template that outputs the data in a table along with the body text and the images:

one-atlantic-center-pdf-4177.pdf

Please take a look at the README on GitHub for instructions and further information/examples.

Cheers

Thanks people,

Please report feedback or ideas for further improvements.

Looks great! Would it be possible to render multiple pages in a single .pdf using this?

Yep. The pdf is generated from a ProcessWire template in /site/templates/pages2pdf/.

Think of it as a normal Pw template: You can use $page, $pages, $users and all other variables to search and output your

content. The only restriction is that you have limited html support, so make sure you use supported html

tags in TCPDF (see link in first post).

There's also another module which generates pdfs from the Admin:

Just dropping in to say that I'll definitely try this module out soon, looks very promising. Thanks for making this!

For the record, I've used mPDF in the past for creating PDF versions of pages. It's HTML and CSS support seemed superior compared to other libraries at the time, at least for my use cases. Might have to switch one site to use this module instead of mPDF just to see how they really compare.

Taking a look at your code I'm seeing quite a bit similarities with these libraries; for an example seem to have identical method names. Interesting. :)

Hi teppo,

Thanks.

This is very interesting, I didn't know mPDF before. Looks very promising if the html support is better plus the whole

library is very lightweight compared toTCPDF.

TCPDF and also mPDF are both extensions of FPDF. Some years ago, I used FPDF but the problem there

is the missung UTF-8 and HTML support.

As most of the libraries seem to depend on FPDF, this now has the advantage that one could easily exchange the library behind the module without changing much code.

Looking forward to your feedback! :)

Hi Wanze, great work and very useful! :)

I have one question: do you plan to embedd the FPDI-Extension into it?

I know it from working with FPDF. In the past FPDI-Extension couldn't bundled with TCPDF a long time because of the licence, but this has changed a few year ago.
 

Would be useful to upload or otherwise specify a PDF as background on a 'per-Template-Basis'. (<= uh, ugly Denglish)

Horst - thanks! :)

Never heard of the FPDI extension. I checked your link and read some docs on the website, but I'm not sure

how this should be integrated here.

Can you give me more details? :)

What do you mean with "background"? As far as I understand, FPDI is used to import pages from other

pdf's into your pdf.

Grüsse nach Deutschland!

Hi Wanze, yes with the FPDI extension you can import other PDFs, but in different ways. What I mean with 'as Background' and what I'm find very useful is, for example:

You can take a PDF with your e.g. Briefkopf , assuming you have a first page with all your stuff (Logo, adress, bankinfo, tax number, etc.) and a second page with less data (maybe a smaller version of your Logo and only name and phone number), and use it as background-layers:

// example use of FPDI-Extension with FPDF.

	$tplfile = 'C:/fpdf/templates/mein_briefkopf.pdf';
	$pagecount = $this->pdf->setSourceFile($tplfile);              // defining the sourcefile returns Pagenumber of it
	for($i=1;$i<=$pagecount;$i++)
	{
		$this->fpdiTemplates['tpl_s'.$i] = $this->pdf->ImportPage($i);     // import each page and assign it to a variable
	}
	$this->Parser_Opened = TRUE;
	$this->Use_Template = $this->fpdiTemplates['tpl_s1'];
	...                                                            // write own stuff to the first page
                                                                       // switch the Template to the second page for all
                                                                       // following pages (optional)
        $this->Use_Template = $this->fpdiTemplates['tpl_s2'];
        ... // create more pages

With the use of FPDI-Templates you can add graphical stuff to your pdf-pages with less effort.

On my website one can add images to a virtual lightbox and can download them as a PDF.

There are three template pages: one for the image pages, one with my contact-data and copyright notice! and optional one for user notes.

..., und viele Grüße in die Schweiz :)

Wow horst - that is super awesome; I'll have to revisit this, because i need something like this for a site i'm currently working on, where there is a product and we want to generate a slick product sheet, downloadable pdf using the existing PW content and images...

Hi Wanze, thanks for all your work on this, I'm excited to try it out.

Problem I have at the moment is the render call isn't outputting anything. I've definitely added my template in the module settings but there's no link or anything getting outputted.

Have you seen this issue before?

Thanks.

Hi onjegolders,

I just noticed that I forgot to add an 'echo' in front of the render call in my first post - updated.

It should be:

echo $modules->get('Pages2Pdf')->render();

Was this the issue? (hope so... :))

Yeah that sorted it thanks Wanze, I should have seen that!

Do you know what differences there are between this implementation and using HTML2PDF?

I have a very basic usage of that library and it seems to work "OK" but I'm guessing a PW way is better. Are there any other differences that you know of?

Thanks again for all your hard work Wanze.

No problem - thanks you for finding this one! ^-^

I've never used html2pdf before, but it looks like it's an addition on top of tcpdf - the framework that this module is using.

Don't know the differences exactly. This module just integrates TCPDF into ProcessWire, making it easier for you to setup

everything. However, it could be the case that html2pdf has better html support built in for rendering the pdfs than tcpdf.

The module handles creating / caching pdf's for you and you can output the content with Pw templates. This means,

you have the full Pw API available if needed.

If anyone can confirm that other libraries, e.g. html2pdf or mPDF have actually better html support than TCPDF, I'll switch the

framework behind the module.

hi wanze, i have a problem with this module.

When i use english characters is working fine and it exports successfully the pdfs.

But with the greek chars i get question marks.

is there any solution for this; i have search the tcpdf examples but i can't make it  to work

thanks.

Hi sakkoulas,

That's because the standard font set by the module does not have those characters included. I removed all fonts but the standard ones from the tcpdf folder so the module doesn't get too heavy.

You can do those steps:

  1. Download TCPDF
  2. Copy all files starting with freesans* or freeserif* to /site/modules/Pages2Pdf/tcpdf/fonts
  3. In your module configs, set freesans/freeserif under Default font

Then the greek characters work (make sure you enable debug mode or save the page to delete any cached pdfs).

I think this is the easiest solution. Disadvantage is that the pdf is a bit heavier due to this font which includes all unicode characters.

Another possibility is to convert a greek font to TCPDF according to the docs: http://www.tcpdf.org/fonts.php

Does this work for you?

      I've created a Process Module, and its execute() function renders the HTML response to an AJAX request. The AJAX request is being made outside of the admin panel, and in all likelihood will be made by "guest" users.
      Within my ModuleName.info.json file, I have added these lines:
      "permission": "generate-thumbnails", "permissions": { "generate-thumbnails": "Generate Thumbnails" }, Then within the Admin panel, I gave guests access to run that module.
      Unless logged in, the response to the AJAX request is always the login form's HTML, rather than the HTML my execute() function creates.
      So two questions:
      Is it possible to give non-logged-in users the ability to run that function via the AJAX request, or Is there a better ProcessWire way to create HTML to use as an AJAX response? Thank you!

      I have had this module sitting in a 95% complete state for a while now and have finally made the push to get it out there. Thanks to @teppo for his Hanna Code Helper module which I referred to and borrowed from during development.
      http://modules.processwire.com/modules/hanna-code-dialog/
      https://github.com/Toutouwai/HannaCodeDialog
      HannaCodeDialog
      A module for ProcessWire CMS/CMF. Provides a number of enhancements for working with Hanna Code tags in CKEditor. The main enhancement is that Hanna tags in a CKEditor field may be double-clicked to edit their attributes using core ProcessWire inputfields in a modal dialog.
      Requires the Hanna Code module.
      Installation
      Install the HannaCodeDialog module using any of the normal methods.
      For any CKEditor field where you want the "Insert Hanna tag" dropdown menu to appear in the CKEditor toolbar, visit the field settings and add "HannaDropdown" to the "CKEditor Toolbar" settings field.
      Module configuration
      Visit the module configuration screen to set any of the following:
      Exclude prefix: Hanna tags named with this prefix will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion. Exclude Hanna tags: Hanna tags selected here will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion. Background colour of tag widgets: you can customise the background colour used for Hanna tags in CKEditor if you like. Dialog width: in pixels Dialog height: in pixels Features
      Insert tag from toolbar dropdown menu
      Place the cursor in the CKEditor window where you want to insert your Hanna tag, then select the tag from the "Insert Hanna tag" dropdown.

      Edit tag attributes in modal dialog
      Insert a tag using the dropdown or double-click an existing tag in the CKEditor window to edit the tag attributes in a modal dialog.

      Tags are widgets
      Hanna tags that have been inserted in a CKEditor window are "widgets" - they have a background colour for easy identification, are protected from accidental editing, and can be moved within the text by drag-and-drop.

      Options for tag attributes may be defined
      You can define options for a tag attribute so that editors must choose an option rather than type text. This is useful for when only certain strings are valid for an attribute and also has the benefit of avoiding typos.
      Add a new attribute for the Hanna tag, named the same as the existing attribute you want to add options for, followed by "__options". The options themselves are defined as a string, using a pipe character as a delimiter between options. Example for an existing attribute named "vegetables":
      vegetables__options=Spinach|Pumpkin|Celery|Tomato|Brussels Sprout|Potato You can define a default for an attribute as normal. Use a pipe delimiter if defining multiple options as the default, for example:
      vegetables=Tomato|Potato Dynamic options
      Besides defining static options as above, you can use one Hanna tag to dynamically generate options for another. For instance, you could create a Hanna tag that generates options based on images that have been uploaded to the page, or the titles of children of the page.
      Your Hanna tag that generates the options should echo a string of options delimited by pipe characters (i.e. the same format as a static options string).
      You will probably want to name the Hanna tag that generates the options so that it starts with an underscore (or whatever prefix you have configured as the "exclude" prefix in the module config), to avoid it appearing as an insertable tag in the HannaCodeDialog dropdown menu.
      Example for an existing attribute named "image":
      image__options=[[_images_on_page]] And the code for the _images_on_page tag:
      <?php $image_names = array(); $image_fields = $page->fields->find('type=FieldtypeImage')->explode('name'); foreach($image_fields as $image_field) { $image_names = array_unique( array_merge($image_names, $page->$image_field->explode('name') ) ); } echo implode('|', $image_names); Choice of inputfield for attribute
      For attributes which you have defined options for, you can choose the inputfield that is used to select from the options.
      Inputfields that support the selection of a single option are select (this is the default inputfield for attributes with options so it isn't necessary to specify it if you want it) and radios.
      Inputfields that support the selection of multiple options are selectmultiple, asmselect and checkboxes.
      You can also specify a checkbox inputfield - this is not for attributes with defined options but will limit an attribute to an integer value of 1 or 0.
      The names of the inputfield types are case-insensitive.
      Example for an existing attribute named "vegetables":
      vegetables__type=asmselect Descriptions and notes for inputfields
      You can add a description or notes to an attribute and these will be displayed in the dialog.
      Example for an existing attribute named "vegetables":
      vegetables__description=Please select vegetables for your soup. vegetables__notes=Pumpkin and celery is a delicious combination. Notes
      When creating or editing a Hanna tag you can view a basic cheatsheet outlining the HannaCodeDialog features relating to attributes below the "Attributes" config inputfield.
      Troubleshooting
      HannaCodeDialog includes and automatically loads the third-party CKEditor plugins Line Utilities and Widget. If you have added these plugins to your CKEditor field already for some purpose and experience problems with HannaCodeDialog try deactivating those plugins from the CKEditor field settings.

      Version 1.1.2 released

      Updated 2016-02-26:
      Officially in the module directory! http://modules.processwire.com/modules/webmention/

      Updated 2016-02-25:
      Version 1.1.0 is now released. It's been submitted to the module directory so should appear there soon. In the meantime, it's available on GitHub: https://github.com/gRegorLove/ProcessWire-Webmention. Please refer to the updated README there and let me know if you have any questions!
      ------------
      Original post:
       
      This is now out of date. I recommend reading the official README.
       
      I've been working on this one for a while. It's not 100%, but it is to the point I'm using it on my own site, so it's time for me to release it in beta. Once I finish up some of the features described below, I will submit it to the modules directory as a stable plugin.
      For now, you can install from Github. It works on PW2.5. I haven't tested on PW2.6, but it should work there.
      Feedback and questions are welcome. I'm in the IRC channel #processwire as well as #indiewebcamp if you have any questions about this module, webmention, or microformats.
      Thanks to Ryan for the Comments Fieldtype which helped me a lot in the handling of webmentions in the admin area.
      ProcessWire Webmention Module
      Webmention is a simple way to automatically notify any URL when you link to it on your site. From the receiver's perspective, it is a way to request notification when other sites link to it.
      Version 1.0.0 is a stable beta that covers webmention sending, receiving, parsing, and display. An easy admin interface for received webmentions is under development, as well as support for the Webmention Vouch extension.
      Features
      * Webmention endpoint discovery
      * Automatically send webmentions asynchronously * Automatically receive webmentions * Process webmentions to extract microformats   Requirements * php-mf2 and php-mf2-cleaner libraries; bundled with this package and may optionally be updated using Composer. * This module hooks into the LazyCron module.   Installation Github: https://github.com/gRegorLove/ProcessWire-Webmention

      Installing the core module named "Webmention" will automatically install the Fieldtype and Inputfield modules included in this package.   This module will attempt to add a template and page named "Webmention Endpoint" if the template does not exist already. The default location of this endpoint is http://example.com/webmention-endpoint   After installing the module, create a new field of type "Webmentions" and add it to the template(s) you want to be able to support webmentions. Sending Webmentions
      When creating or editing a page that has the Webmentions field, a checkbox "Send Webmentions" will appear at the bottom. Check this box and any URLs linked in the page body will be queued up for sending webmentions. Note: you should only check the "Send Webmentions" box if the page status is "published."   Receiving Webmentions This module enables receiving webmentions on any pages that have have "Webmentions" field, by adding the webmention endpoint as an HTTP Link header. If you would like to specify a custom webmention endpoint URL, you can do so in the admin area, Modules > Webmention.   Processing Webmentions (beta) Currently no webmentions are automatically processed. You will need to browse to the page in the backend, click "Edit," and scroll to the Webmentions field. There is a dropdown for "Visibility" and "Action" beside each webmention. Select "Process" to parse the webmention for microformats.   A better interface for viewing/processing all received webmentions in one place is under development.   Displaying Webmentions (beta) Within your template file, you can use `$page->Webmentions->render()` [where "Webmentions" is the name you used creating the field] to display a list of approved webmentions. As with the Comments Fieldtype, you can also generate your own output.   The display functionality is also under development.   Logs This module writes two logs: webmentions-sent and webmentions-received.   Vouch The Vouch anti-spam extension is still under development.   IndieWeb The IndieWeb movement is about owning your data. It encourages you to create and publish on your own site and optionally syndicate to third-party sites. Webmention is one of the core building blocks of this movement.   Learn more and get involved by visiting http://indiewebcamp.com.   Further Reading * http://indiewebcamp.com/webmention * http://indiewebcamp.com/comments-presentation * http://indiewebcamp.com/reply
