Wow, just checked those examples on github. they're looking really good..maybe I'll change my custom mpdf thing to your wirepdf. 

But I'm doing screencasts for the customer and we're going live pretty soon, so no time right now..

nice work again wanze :) headsup

Great input, thanks Wanze!

At the moment I'm waiting for the go from my client. They haven't signed off the project yet. So I'm still in the research phase. Once I start real work on the project I surely will consider your recommendations and will then keep you updated on my progress.

WirePDF module looks promising.

Have you ever experimented with client side PDF creation libraries like https://github.com/MrRio/jsPDF ?

Thanks Can, good luck with your project :)

The new version is now merged into the master branch, I also updated the README on GitHub.

With v.1.1.1, a new config option was introduced: Creation mode
This setting controls when the PDF files are generated and stored for caching purposes. The default value is still "on click", right before downloading a PDF file.

Now, the PDF files can also be created when saving pages in the ProcessWire admin. This new option is preferable if the PDFs are heavy and need some time for processing - the clients won't have to wait for it.

Please post any problems or questions regarding updating the module to the new version in this thread.

You're welcome.

I don't have any experience with client side PDF creation tools. I have done some work with TCPDF in the past and now mPDF because the HTML/CSS support is better though still limited. If you need very complex layouts then maybe it is better to not use HTML at all but the native stuff from these libraries, e.g. positioning the cursor and output text/shapes/images exactly where you need it.

Personally, I prefer a server-side solution because JS can be manipulated by the visitor, not sure how to deal with saving PDF files then. On the other hand, if the PDF files are always created "on the fly", why not - if enough browser support is given.

@Wanze

I set up a quick and dirty test for jsPDF library here: http://jspdf.webseiten-fuer-alle.de/

Underneath "Choose example" select "**NEW: addHTML()" and you will see the result instantly

It handles floating images and divs very well.

I like the way you can just drop in a complete HTML page and the result seems to be almost exactly what you see in the browser. So no more extra pdf templates. Definitely looks promising.

As for saving the pdfs, that's a good question. Browser support seems to be fine.

@nfil: just a quick thought: you may try to use the file:/// protocol (with three slashes), e.g.

echo "<TD WIDTH='25%'><img src=\"file:///{$someImgThumb->filename}\" width=\"{$someImgThumb->width}\" height=\"{$someImgThumb->height}\" /></TD>";

Haven't tested and don't know if it can work with mpdf, - just a quick thought. :)

@horst Thanks horst but the file:/// protocol doesn't seem to work but I will keep the tip in mind for other use in PW  :)

hello wanze. Thanks for the update. I have tested it, but now it does not render the images, I have this is my template:

if (count($page->images)) {
$someImages = $page->images->slice(0, 4);
foreach ($someImages as $someImg) {
	$someImgThumb = $someImg->size(290, 195);
	echo "<TD WIDTH='25%'><img src=\"{$someImgThumb->url}\" width=\"{$someImgThumb->width}\" height=\"{$someImgThumb->height}\" /></TD>";
}
}

I followed your instructions, is there some other way to render the images?

update: the new updated module was not generating the images in MAMP is working fine on a live host.

I can now also view the pdfs as a guest on the live host, in the previous version, even after saving the page as a superuser, after login off I could not view the pdfs in the live host. It seems to be working very well now. Thanks again waze for this great module.

Hi nfil,

Thanks and good to hear that it works on the live host. Though it's strange that it does not work locally, images are working fine here, also using MAMP. Using the file:// protocol should not be necessary. Another possibilty could be that you'v seen a cached version, if you enable the debug mode the module makes sure you always get a fresh PDF file.

Yes Wanze, thanks for keeping an excellent support. After a few tests I think it was indeed related with cache, it is working now in MAMP with PW 2.4.8 but at the time I was uploading the site from MAMP to a live server and noticed some weird behaviour using MAMP. I copied the live host version today and tested it today again on MAMP and it works flawlessly.  :)

I've this image that is printed to the pdf if the value of the field is filled in the backend and its above 500000 but there are two variables, if one is not populated it will go to the next condition and print the value. How do I go about this one? Thanks.

  // image for output
  $visalogo = $pages->get("/")->logo_eurovisa;
  // if visavalue_b field is not populated it will show visavalue_a
  $visavalue_a = $page->price_a;
  $visavalue_b = $page->price_b;
  $count = "count()>1";
  // $visavalue_b is populated now check if it is greater than 500000
  if ($visavalue_b->($count)>=500000) {
    echo "<img src=\"{$visalogo->url}\" width=\"300\" height=\"176\" />"; 
    } else {
  if ($visavalue_a>=500000); { echo "<img src=\"{$visalogo->url}\" width=\"300\" height=\"176\" />"; 
  }
 }

It should be something like this, count is for numberOfimagesChildren etc but I'm a newbie.

// image for output  
$visalogo = $pages->get("/")->logo_eurovisa; 
// if visavalue_b field is not populated it will show visavalue_a  
$visavalue_a = $page->price_a;  $visavalue_b = $page->price_b;  
// value is populated and greater than  
if(empty($visavalue_b)) {  $va = $visavalue_a>=500000;  
if ($va)   echo "";  }  $vb = $visavalue_b>=500000; 
if ($vb) {  echo "";  }
Sorry for being a bit off topic.

Hi nfil,

I'm not sure, what's the issue? Is it the image that is not working?

If it is not related to mpdf, try to put your code in a "normal" Pw template under /site/templates/ and check if it works there.

When everything's correct, this module should render the same output. If there are differences, that is due to limited HTML/CSS support, but the images should work.

The first code example contains some errors, for example you can't write this:

$count = "count()>1";
  // $visavalue_b is populated now check if it is greater than 500000
  if ($visavalue_b->($count)>=500000) {

The second example contains no image output?

Sorry I don't have time to debug, I'm away some weeks from tomorrow and I need to pack all my stuff :)

If you have questions to general stuff Pw or PHP related, I'm sure other members can help you in this awesome forum somwhere.

Cheers

Hello wanze in the second example I was writing it on a tablet and some code was lost.

It's a over complicated snippet by a newbie like me to check if a field is empty than render another, also checking if both of these fields are higher or equal to 500000

  // image for output
  $visalogo = $pages->get("/")->logo_eurovisa;
  // if visavalue_b field is not populated it will show visavalue_a
  $visavalue_a = $page->price_a;
  $visavalue_b = $page->price_b;
  // value is populated and greater than
  if(empty($visavalue_b)) {
  $va = $visavalue_a>=500000;
  if ($va) 
  echo "<img src=\"{$visalogo->url}\" width=\"300\" height=\"176\" />";
  }
  $vb = $visavalue_b>=500000;
  if ($vb) {
  echo "<img src=\"{$visalogo->url}\" width=\"300\" height=\"176\" />";
  }

hey guys, im using Pages2Pdf v1.0.1 and its been great as far, I have two questions:

echo '<table>';
  foreach($images as $image){
    $imageSmall = $image;
    echo '<tr><td><img id="'. $image->basename . $image->created .'" src="'. $imageSmall->url. '" /></td></tr>';
  }
echo '</table>';
<style>
.head {
	font-family: Times;
	font-weight: bold;
	font-size: 13pt;
}
table{
	text-align: center;
	vertical-align: middle;
	padding: 0;
	width: 100%;
}
img{
	margin: 0 auto;
}
</style>
  • Is there a way of bypassing the cache and making a request for a new pdf everytime? so that it creates a pdf with a timestamp maybe?

Hi, im on mobile sorry for short answers.

1) not sure why it happens. You could try to update the module. The new pdf engine behind has better html and css support. You'd need to separate your css into a separate css file thought, see instructions on one of my earlier posts.

2) setting the cache time to zero will always generate a new pdf file.

Cheers

Hello wanze.

I have a datetime field in my page with the Date/Time Output Format Code j/n/y

PW outputs the formatted date, yet Pages2Pdf will not render the j/n/y format.
 
Have you tried creating a pdf with a datetime field? Or am I doing something wrong. Thanks.
 
update: I get different results, this was probably due to PW dev 2.4.5 I tested your module with PW 2.5 and seems to be fine.

For anyone getting a screen full with “Warning: Cannot modify header information”

This is because you probably have Processwire in debug mode ($config->debug = true;)

Thx WillyC this old thread gave the answer

And thank you too Wanze for this great module.

Hello.

i'm trying to install this module, but i have an error: 

Module is not installable because not all required dependencies are currently met.

says it need the module "WirePDF". In the documentation, says: 

WirePDF

This module is a wrapper around the mPDF library. It is used by the Pages2Pdf module to create and store the PDF files, but can also be used independently to create/store/download PDF files.

how do i create this wrapping, and make the module work?

thanks

Hi Isag,

The WirePDF module is included in Pages2Pdf, you should find it in your modules list.

After installing "WirePDF", you should be able to install "Pages2Pdf"... I'm not sure why this is not working out of the box, I thought that ProcessWire would install the dependencies automatically, if available. What version of Pw are you running?

Cheers

@wanze: this may depend of the increased or somehow changed usage of modules cache since PW 2.5.

@Isag: Just for testing: I would try to hit refresh in the modules section manually. And then give it a new go.

@wanze: Maybe you can add a $this->modules->resetCache(); to the first line of your install routine?

@Isag: which PW version you are using? PW 2.5.??

@lsag: I had the same issue trying to install via classname just now, on v2.5, but it installs fine if you just download from the module page and manually upload to your PW.

Hello. Could someone tell me what i have to put in this template file? is it like a normal processwire template?

checking the default template, i see 

$page->body

shouldn't this get me the entire content of the <body> tag? instead i get, as the only content, the page's url.

Thanks for the patience to this noob

H Isag,

In the template files inside /site/templates/pages2pdf you put the markup that is rendered in the PDF file. It's like a "normal" ProcessWire template.

The $page->body does not output the content of the body tag. It outputs the value of a field called "body". This is just an example, you can output other fields and use the ProcessWire API to build your output.

Cheers

Hello @ all,

I have setted up a multilanguage site and the Pages2pdf module provides the pdf for a page only in one language. Has someone tried to get one pdf-document for each language and how?

I cant figure out how this could be achieved (if it is possible).

Best regards Jürgen

      Happy new year, everybody 🥬
      I've been sitting on this Dashboard module I made for a client and finally came around to cleaning it up and releasing it to the wider public. This is how it looks.
      ProcessWire Dashboard

      If anyone is interested in trying this out, please go ahead! I'd love to get some feedback on it. If this proves useful and survives some real-world testing, I'll add this to the module directory.
      Download
      You can find the latest release on Github.
      Documentation
      Check out the documentation to get started. This is where you'll find information about included panel types and configuration options.
      Custom Panels
      My goal was to make it really simple to create custom panels. The easiest way to do that is to use the panel type template and have it render a file in your templates folder. This might be enough for 80% of all use cases. For anything more complex (FormBuilder submissions? Comments? Live chat?), you can add new panel types by creating modules that extend the DashboardPanel base class. Check out the documentation on custom panels or take a look at the HelloWorld panel to get started. I'm happy to merge any user-created modules into the main repo if they might be useful to more than a few people.
       Disclaimer
      This is a pre-release version. Please treat it as such — don't install it on production sites. Just making sure 🍇
      Roadmap
      These are the things I'm looking to implement myself at some point. The wishlist is a lot longer, but those are the 80/20 items that I probably won't regret spending time on.
      Improve documentation & add examples ⚙️ Panel types Google Analytics ⚙️ Add new page  🔥 Drafts 🔥 At a glance / Page counter 404s  Layout options Render multiple tabs per panel panel groups with heading and spacing between ✅ panel wrappers as grid item (e.g. stacked notices) ✅ Admin themes support AdminThemeReno and AdminThemeDefault ✅ Shortcuts panel add a table layout with icon, title & summary ✅ Chart panel add default styles for common chart types ✅ load chart data from JS file (currently passed as PHP array) Collection panel support image columns ✅ add buttons: view all & add new ✅

      This module is inspired by and similar to the Template Stubs module. The author of that module has not been active in the PW community for several years now and parts of the code for that module didn't make sense to me, so I decided to create my own module. Auto Template Stubs has only been tested with PhpStorm because that is the IDE that I use.
      Auto Template Stubs
      Automatically creates stub files for templates when fields or fieldgroups are saved.
      Stub files are useful if you are using an IDE (e.g. PhpStorm) that provides code assistance - the stub files let the IDE know what fields exist in each template and what data type each field returns. Depending on your IDE's features you get benefits such as code completion for field names as you type, type inference, inspection, documentation, etc.
      Installation
      Install the Auto Template Stubs module.
      Configuration
      You can change the class name prefix setting in the module config if you like. It's good to use a class name prefix because it reduces the chance that the class name will clash with an existing class name.
      The directory path used to store the stub files is configurable.
      There is a checkbox to manually trigger the regeneration of all stub files if needed.
      Usage
      Add a line near the top of each of your template files to tell your IDE what stub class name to associate with the $page variable within the template file. For example, with the default class name prefix you would add the following line at the top of the home.php template file:
      /** @var tpl_home $page */ Now enjoy code completion, etc, in your IDE.

      Adding data types for non-core Fieldtype modules
      The module includes the data types returned by all the core Fieldtype modules. If you want to add data types returned by one or more non-core Fieldtype modules then you can hook the AutoTemplateStubs::getReturnTypes() method. For example, in /site/ready.php:
      // Add data types for some non-core Fieldtype modules $wire->addHookAfter('AutoTemplateStubs::getReturnTypes', function(HookEvent $event) { $extra_types = [ 'FieldtypeDecimal' => 'string', 'FieldtypeLeafletMapMarker' => 'LeafletMapMarker', 'FieldtypeRepeaterMatrix' => 'RepeaterMatrixPageArray', 'FieldtypeTable' => 'TableRows', ]; $event->return = $event->return + $extra_types; }); Credits
      Inspired by and much credit to the Template Stubs module by mindplay.dk.

      Jumplinks for ProcessWire
      Release: 1.5.60
      Composer: rockett/jumplinks
      ⚠️ NOTICE: 1.5.60 is an important security patch-release for an XSS vulnerability discovered by @phlp. It's HIGHLY RECOMMENDED that all Jumplinks users update to the latest version as soon as possible.
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy! 🙂
