Is there an easy way to remove the space occupied by the header? It's probably me or my setup but I can't seem to remove the space.

Maybe you can set the headerMargin setting to zero in the WirePDF module configuration? Do you print the header?

Hi @Wanze, i tried it all:

 

<img src="<?=$mandant->teaserbild->first()->height('100')->url;?>" width="<?=$mandant->teaserbild->first()->height('100')->width;?>" height="100" alt="logo" />

// AND

<img src="<?=$mandant->teaserbild->first()->height('100')->httpUrl;?>" width="<?=$mandant->teaserbild->first()->height('100')->width;?>" height="100" alt="logo" />

// AND ALSO

$imagedata = file_get_contents($mandant->teaserbild->first()->height('100')->filename);
$base64Img = "data:image/png;base64," . base64_encode($imagedata);
<img src="<?=$base64Img;?>" width="<?=$mandant->teaserbild->first()->height('100')->width;?>" height="100" alt="logo" />

 

but nothing works. How do I enable debug mode (showImageErrors) for the pdf module?

 

Thanks,

thomas

Strange update:

 

$pdf->save();

shows the images, but

$pdf->download();

doesn't. Not sure what's going on here but I can work around that.

Thanks,

thomas

Greeting,

I need help to use a font 'dejavusans'? I have problems with the display Croatian letters š, đ, č, ć, ž.

I use

$pdf = $modules->get('WirePDF');

but I can not set the font 'dejavusans'

<?php

$pdf = $modules->get('WirePDF');

$mpdf = $pdf->mpdf;

$pdfPath = $config->paths->files . $page->id . "/" . $page->title.'.pdf';
$stylesheet = file_get_contents($config->paths->templates.'/pages2pdf/styles.css');

$wireSendOptions = array('exit' => false, 'forceDownload' => false, 'downloadFilename' => '');

$mpdf->WriteHTML($stylesheet,1);

$html = "";
$html .= "<html lang='hr'><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /></head><body>";
$html .= '<table border=0>';
$html .= 'text example š đ č ć ž';
$html .= "</body></html>";
$mpdf->WriteHTML($html);

$mpdf->Output($pdfPath, 'F');
wireSendFile($pdfPath, $wireSendOptions );
?>

Wanze, yes thanks. I was missing the configuration options on the WirePDF module (was checking only the Pages2PDF module configuration).

I'm trying to use this module to create a PDF of a page on my website. I've tried following along with this thread and the tutorials, etc on Github but I'm still having trouble getting it to work correctly. The page in question is vector.houseofdeadleg.co.uk. If you click on the button the pdf downloads but only includes a header and footer, and any text on the page. I can't get the images to be included.

I have this installed on PW3 and my supposed pages2pdf link simply loads the page with the get variable specified ={page.id}, not as a PDF. What could be the matter?

Does anybody know how to solve with Pages2Pdf second page content top margin?, I attach an image so you can see that the paragraph hasn't got any padding or margin although is set.

see the docs and examples on that page: https://mpdf.github.io/reference/mpdf-functions/addpagebyarray.html

$mpdf->AddPageByArray(array(
    'orientation' => 'L',
    'mgl' => '50',
    'mgr' => '50',
    'mgt' => '50',
    'mgb' => '50',
    'mgh' => '10',
    'mgf' => '10',
    ));

mgt = page margin from the top (where regular text starts, in the example it would start 50mm below the top)

mgh = margin for the header (where the header text ends, in the example it would end 10mm from the top)

looks fine to me. try it with an empty pdf and the most simple headers & texts possible. maybe your header is just too large and it cannot shrink it (because it's not intended).

mpdf is often trial&error ;)

The page you try to download the PDF from (the given ID via get parameter) must:

  • Be viewable for the current user
  • Its template must be allowed to create PDFs (see the module config)

Otherwise you should debug around this line:

Did you check the settings in the WirePDF module? You can define the margin there, which should be the same for all pages. If it is not working on just one page, there might be a problem with the markup. Maybe you can introduce some manual page breaks for testing this, please see the mpdf documentation for this feature.

Hello there,

I tried to use SVG files in image tags and some of the vector paths are "destroyed" and everything in the SVG is black.

Then in tried inlining the SVG:

if( $img->ext == "svg")
    echo "<div class'card__img'>".file_get_contents($img->filename)."</div>";
else
    echo "<img class='card__img' src='{$img->url}'>";

This outputs a small icon with a red "X" … meaning; "file not found" … I guess.

Before one of the icons there was this line in the PDF:

<?xml version="1.0" encoding="utf-8"?>

So this means the module found the file but did not render the content.

(… and YES, I saw there is a module "ImageRasterizer", but unfortunately it requires Imagemagick and the pecl imagick extension.)

hi alf and welcome to the forum

did you read the docs of mpdf regarding svg? https://mpdf.github.io/what-else-can-i-do/images.html

maybe there is some helpful information..

@bernhard

No, but I read the PDF (http://www.mpdfonline.com/repos/mpdfmanual.pdf) and as far as I can see it has the same content … how ever … SVGs "should" work.

So the question is if there is a problem with the module or with my installation or who knows? … if nothing works, I will disable SVG files and I will use PNGs instead …

Just in case someone else encounters the same problem:

I had to migrate a whole website to PW and during tests I imported around 200 pages. Now I wanted to delete them and start the real import process. To get rid of the test pages I tried to delete them with adrians AdminActions, but got an error message and nothing was deleted:

Error: Call to a member function path() on a non-object (line 261 of /xxx/site/assets/cache/FileCompiler/site/modules/Pages2Pdf/Pages2Pdf.module) 

I had to detach the template in question in Pages2Pdf settings. Then it worked and I was able to delete the pages.

Same error with a ListerPro Action(Delete), so I asume it's a problem with Pages2Pdf...

I've just added this module to a dev site and when trying to call the module for rendering I'm getting an error – Parse Error: syntax error, unexpected ',' (line 8910 of /Applications/MAMP/htdocs/xxx/site/modules/WirePDF/mpdf/mpdf.php)

 

Additional:

Looking at WirePDF module, it was saying I had two versions, one in the Pages2PDF folder and one separate one, I think one might be a Handover from a previous attempt to use teh same module. I deleted the Pages2PDF folder and the WirePDF one and did a fresh install, now I get teh error message  Compile Error: 'break' not in the 'loop' or 'switch' context (line 2416 of /Applications/MAMP/htdocs/xxx/site/modules/Pages2Pdf/mpdf/classes/svg.php)

What PHP version are you using? These kind of errors make me guess that mpdf is not compatible with your PHP version. Can you try to use the dev branch of the module via GitHub?

I have this

$pdf = $modules->get('Pages2Pdf')->render(array(
  'title' => 'PDF',
  'markup' => '<a href=\'{url}\' target=\'_blank\'>{title}</a>',
  'page_id' => '',
));

$content .= <<<EOT
<script type="text/javascript">
  $("h1").append(" <small>[$pdf]</small>");</script>
</script>
EOT;

which outputs to /?pdf={pid} but clicking the link just opens the current page in a new tab, no PDF.

Also having a problem with images..

On some pages the PDF shows the image, on other pages the image is missing.

<img src="<?= $page->navimg->url ?>" width="220"/>

try outputting the image url as plaintext

<p><?= $yourimage->url ?></p>

also check the return setting of your images field. it can be set as array or single image. if it is set as array you would have to define wich image to show (eg $yourimages->first()->url )

Hi bernhard,

thank you for the hint.  The image field is set as single element.
 

  <td colspan="1" style="padding:15px">
    <img src="<?= $page->navimg->url; ?>" width="220"/>
    <p><?= $page->navimg->url ?></p>
  </td>

something between ..

<?php if ($page->images->count > 0) : ?>
<table>
  <tr>
  <?php
    $gallery = $page->images;
    $gallery = $gallery->slice(0,4);
   foreach ($gallery as $image): ?>
    <td>
      <img src="<?= $image->size(200, 200)->url ?>" width="200" height="200"/>
    </td>
  <?php endforeach; ?>
  </tr>
</table>
<?php endif; ?>

 

template part:

<?php 
$optionspdf = array(
  'title' => 'Datenblatt',
  'markup' => '<a class="uk-button gaming" href="{url}" download>{title}</a>',
  'pageFormat' => 'A4'
);
echo $modules->get('Pages2Pdf')->render($optionspdf);
?>

 

result:

@maxf5 Can you check if the image is existing on your hard drive by looking at the file in /site/assets/files? Recently I had a problem in ProcessWire that my thumbnails were not getting generated correctly if I was using numbers like 100,200,300,400 for the dimensions. Strangely it worked by using other dimensions like 110, 390 etc.

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules DeepL offers translations to the following languages: English (US), English (UK), German, French, Spanish, Portuguese (EU), Portuguese (Brazil, Italian, Dutch, Polish, Russian, Japanese, Chinese (Simplified)
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. This tool is available for all users with the page-edit permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

       
      Limitations:
      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Gitlab issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Gitlab page and file a bugfix ticket.
      Requirements:
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      It's Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader). The only cost to use this is a subscription fee for the DeepL Pro API.

      PageImage Manipulator, API for version 1 & 2

      The Page Image Manipulator is a module that let you in a first place do ImageManipulations with your PageImages. - And in a second place there is the possibility to let it work on any imagefile that exists in your servers filesystem, regardless if it is a 'known PW-image'.

      The Page Image Manipulator is a Toolbox for Users and Moduledevelopers. It is written to be as close to the Core ImageSizer as possible. Besides the GD-filterfunctions it contains resize, crop, canvas, rotate, flip, sharpen, unsharpMask and 3 watermark methods.



      How does it work?

      You can enter the ImageManipulator by calling the method pim2Load(). After that you can chain together how many actions in what ever order you like. If your manipulation is finished, you call pimSave() to write the memory Image into a diskfile. pimSave() returns the PageImage-Object of the new written file so we are able to further use any known PW-image property or method. This way it integrates best into the ProcessWire flow.

      The three examples above put out the same visual result: a grayscale image with a width of 240px. Only the filenames will slightly differ.

      You have to define a name-prefix that you pass with the pimLoad() method. If the file with that prefix already exists, all operations are skipped and only the desired PageImage-Object gets returned by pimSave(). If you want to force recreation of the file, you can pass as second param a boolean true: pim2Load('myPrefix', true).

      You may also want to get rid of all variations at once? Than you can call $pageimage->pim2Load('myPrefix')->removePimVariations()!

      A complete list of all methods and actions are at the end of this post.
       
      You may also visit the post with tips & examples for users and module developers.


      How to Install
      Download the module Place the module files in /site/modules/PageImageManipulator/ In your admin, click Modules > Check for new modules Click "install" for PageImageManipulator Done! There are no configuration settings needed, just install and use it. Download    (version 0.2.0)
      get it from the Modules Directory History of origins

      http://processwire.com/talk/topic/3278-core-imagemanipulation/


      ----------------------------------------------------------------------------------------------------------


      Page Image Manipulator - Methods

      * pimLoad  or  pim2Load, depends on the version you use!

      pimLoad($prefix, $param2=optional, $param3=optional)
      param 1: $prefix - (string) = mandatory! param 2: mixed, $forceRecreation or $options param 3: mixed, $forceRecreation or $options return: pim - (class handle) $options - (array) default is empty, see the next method for a list of valid options! $forceRecreation - (bool) default is false It check if the desired image variation exists, if not or if forceRecreation is set to true, it prepares all settings to get ready for image manipulation
      -------------------------------------------------------------------

      * setOptions

      setOptions(array $options)
      param: $options - (array) default is empty return: pim - (class handle) Takes an array with any number valid options / properties and set them by replacing the class-defaults and / or the global config defaults optionally set in the site/config.php under imageSizerOptions or imageManipulatorOptions.

      valid options are:
      quality = 1 - 100 (integer) upscaling = true | false (boolean) cropping = true | false (boolean) autoRotation =true | false (boolean) sharpening = 'none' | 'soft' | 'medium' | 'strong' (string) bgcolor = (array) css rgb or css rgba, first three values are integer 0-255 and optional 4 value is float 0-1, - default is array(255,255,255,0) thumbnailColorizeCustom = (array) rgb with values for colorize, integer -255 - 255 (this can be used to set a custom color when working together with Thumbnails-Module)
        outputFormat = 'gif' | 'jpg' | 'png' (Attention: outputFormat cannot be specified as global option in $config->imageManipulatorOptions!) set {singleOption} ($value)
      For every valid option there is also a single method that you can call, like setQuality(90), setUpscaling(false), etc.
      -------------------------------------------------------------------

      * pimSave

      pimSave()
      return: PageImage-Object If a new image is hold in memory, it saves the current content into a diskfile, according to the settings of filename, imagetype, targetFilename and outputFormat. Returns a PageImage-Object!
      -------------------------------------------------------------------

      * release

      release()
      return: void (nothing) if you, for what ever reason, first load image into memory but than do not save it, you should call release() to do the dishes! 😉 If you use pimSave() to leave the ImageManipulator, release() is called automatically.
      -------------------------------------------------------------------

      * getOptions

      getOptions()
      return: associative array with all final option values example:
      ["autoRotation"] bool(true) ["upscaling"] bool(false) ["cropping"] bool(true) ["quality"] int(90) ["sharpening"] string(6) "medium" ["targetFilename"] string(96) "/htdocs/site/assets/files/1124/pim_prefix_filename.jpg" ["outputFormat"] string(3) "jpg" get {singleOption} ()
      For every valid option there is also a single method that you can call, like getQuality(), getUpscaling(), etc. See method setOptions for a list of valid options!
      -------------------------------------------------------------------

      * getImageInfo

      getImageInfo()
      return: associative array with useful informations of source imagefile example:
      ["type"] string(3) "jpg" ["imageType"] int(2) ["mimetype"] string(10) "image/jpeg" ["width"] int(500) ["height"] int(331) ["landscape"] bool(true) ["ratio"] float(1.5105740181269) ["bits"] int(8) ["channels"] int(3) ["colspace"] string(9) "DeviceRGB" -------------------------------------------------------------------

      * getPimVariations

      getPimVariations()
      return: array of Pageimages Collect all pimVariations of this Pageimage as a Pageimages array of Pageimage objects. All variations created by the core ImageSizer are not included in the collection.

      smooth($level=127)
      param: $level - (integer) 1 - 255, default is 127 return: pim - (class handle) Smooth is the opposite of sharpen. You can define how strong it should be applied, 1 is low and 255 is strong.
      -------------------------------------------------------------------

      * blur

      blur()

      * watermarkLogo

      watermarkLogo($pngAlphaImage, $position='center', $padding=2)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 5, padding to the borders in percent of the images length! return: pim - (class handle) You can pass a transparent image with its filename or as a PageImage to the method. If the watermark is bigger than the destination-image, it gets shrinked to fit into the targetimage. If it is a small watermark image you can define the position of it:
      NW - N - NE | | | W - C - E | | | SW - S - SE  
      The easiest and best way I have discovered to apply a big transparency watermark to an image is as follows:
      create a square transparent png image of e.g. 2000 x 2000 px, place your mark into the center with enough (percent) of space to the borders. You can see an example here! The $pngAlphaImage get centered and shrinked to fit into the memory image. No hassle with what width and / or height should I use?, how many space for the borders?, etc.
      -------------------------------------------------------------------

      * watermarkLogoTiled

      watermarkLogoTiled($pngAlphaImage)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency return: pim - (class handle) Here you have to pass a tile png with transparency (e.g. something between 150-300 px?) to your bigger images. It got repeated all over the memory image starting at the top left corner.
      -------------------------------------------------------------------

      * watermarkText

      watermarkText($text, $size=10, $position='center', $padding=2, $opacity=50, $trueTypeFont=null)
      param: $text - (string) the text that you want to display on the image param: $size - (integer) 1 - 100, unit = points, good value seems to be around 10 to 15 param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 2, padding to the borders in percent of the images length! param: $opacity- (integer) 1 - 100, default is 50 param: $trueTypeFont - (string) systemfilepath to a TrueTypeFont, default is freesansbold.ttf (is GPL & comes with the module) return: pim - (class handle) Here you can display (dynamic) text with transparency over the memory image. You have to define your text, and optionally size, position, padding, opacity for it. And if you don't like the default font, freesansbold, you have to point to a TrueTypeFont-File of your choice.

      PageImage Manipulator - Example Output


    • By d'Hinnisdaël
      Format Datetime fields as Carbon instances.
      You can find the latest release and the complete readme on Github.
      Installation
      composer require daun/datetime-carbon-format Usage
      All Datetime fields will now be formatted as Carbon instances instead of strings. Some examples:
      // $page->date is a Datetime field // Output format: j/n/Y echo $page->date; // 20/10/2020 echo $page->date->add('7 days'); // 27/10/2020 echo $page->date->format('l, F j'); // Monday, October 20 echo $page->date->year; // 2020 echo $page->date->diffForHumans(); // 28 minutes ago Frontend only
      The ProcessWire admin seems to expect datetime fields to be strings. This module will only return Carbon instances on frontend page views.
      Date output format
      When casting a Carbon instance to a string (usually when outputting the field in a template), the field's date output format will be respected.

      TrelloWire
      This is a module that allows you to automatically create Trello cards for ProcessWire pages and update them when the pages are updated. This allows you to setup connected workflows. Card properties and change handling behaviour can be customized through the extensive module configuration. Every action the module performs is hookable, so you can modify when and how cards are created as much as you need to. The module also contains an API-component that makes it easy to make requests to the Trello API and build your own connected ProcessWire-Trello workflows.
      Warning: This module requires ProcessWire 3.0.167 which is above the current stable master release at the moment.
      Features
      All the things the module can do for you without any custom code: Create a new card on Trello whenever a page is added or published (you can select applicable templates). Configure the target board, target list, name and description for new cards. Add default labels and checklists to the card. Update the card whenever the page is updated (optional). When the status of the card changes (published / unpublished, hidden / unhidden, trashed / restored or deleted), move the card to a different list or archive or delete it (configurable). You can extend this through hooks in many ways: Modifiy when and how cards are created. Modify the card properties (Target board & list, title, description, et c.) before they are sent to Trello. Create your own workflows by utilizing an API helper class with many convenient utility methods to access the Trello API directly. Feedback & Future Plans
      Let me know what you think! In particular:
      If you find any bugs report them here or on Github, I'll try to fix them. This module was born out of a use-case for a client project where we manage new form submissions through Trello. I'm not sure how many use-cases there are for this module. If you do use it, tell me about it! The Trello API is pretty extensive, I'll try to add some more helper methods to the TrelloWireApi class (let me know if you need anything in particular). I'll think about how the module can support different workflows that include Twig – talk to me if you have a use-case! Next steps could be a dashboard to manage pages that are connected to a Trello card, or a new section in the settings tab to manage the Trello connection. But it depends on whether there is any interest in this 🙂 Links
