PDF Fieldtype/Inputfield

Recommended Posts

@ICF Church Hi, I'm trying to solve your issue, but I can't reproduce the error. What version of PHP are you using? During module installation there is a step where the `use` statemenents in source files under FieldtypePDF folder are prefixed with `Processwire\' namespace if PW 3.x detected. Could you please examine what's wrong? Look into this method https://github.com/uiii/ProcessWire-FieldtypePDF/blob/d11ff962d520782fa25215f5ce606886773a5a44/FieldtypePDF.module#L232. Thanks

@ICF Church Hi, I've released new version which should fix your problem, I know it is a little bit late but if you are still interested, you may try it.

I didn't face the error before but now, there are some misterious ways to me how PW detect module updates and sometimes detect the updated module as a new module so the `upgrade` method is not executed and the namespaces are not fixed which leads to the error mentioned by you. So I've moved the 'namespaces fix' code to the init method so it will check if the namespaces are fixed each time the module is initialized.

It may happed that you will see the 'Fieldtype 'FieldtypePDF' does not exist' when updating the module, just hit the refresh button again and you are fine.

Hi @Richard Jedlička

thanks a lot for this useful modul!!
Unfortunately i am running into following issue.
When trying to upload a PDF i get this error and the upload fails.

Failed to read the file (in /wire/modules/Inputfield/InputfieldFile/InputfieldFile.module line 790)

I´m using PW 3.0.95 - and the FieldtypePDF 1.1.5.
PHP Version: 7.2.4
ImageMagick: I
mageMagick 6.9.4-6 Q16 i686 2016-06-03

Do you know anything about this?

How did you install the module? If you copied the files manually I am guessing this is simply a file permissions issue - make sure everything has the correct owner and permissions that allow reading of the files.

Hi all,

tried several things.....changed the php-version on the Server (down to 7.0). Updating pw to the latest master (123). Uninstalling and installing the module again.

the result is the same.

could there be any problem with the server (mittwald) to handle pdf-files in terms of security?

any thoughts or suggestions?



The PHP-Version has to be 7.0.32 CGI - now it works!!

I just ran into this on my development server (using PHP7.2)

The clues to a fix were found here.  NB, this module doesn't need ImageMagick/Ghostscript to have write permissions for PDFs to generate the thumbnails, read permission worked just fine for me.

  <policy domain="coder" rights="read" pattern="PDF" />

Hi @ThomasH

In file PagePDF.php on lines 32,33,34 change to:

use ProcessWire\Pagefile;
use ProcessWire\Pageimage;
use ProcessWire\Pageimages;

and in file PagePDFs.php add ProcessWire\ namespace for Pagefiles as well (on line 29)

BTW @Richard Jedlička very useful module for me now 🙂 Thanks a lot!

Working on PW 3.0.133, PHP 7.3.8 FPM (FieldtypePDF v. 1.1.5)

First of all many thanks to @Richard Jedlička for this great module. It does exactly what I was looking for, unfortunately I have a problem with the generated thumbnails: German umlauts are simply not displayed. In the ImageMagick documentation I can't find any hint and can only assume that it is somehow related to Ghostscript?

Maybe someone of you already had the same problem found and a solution?

Many thanks in advance!

No umlauts in the cover/screenshot of your uploaded PDF?
Do you use some special fonts in the PDF which are not embedded?

I got the module working somehow and threw a ton of PDFs at it and there were lots of ä,ö,ü and ß.

Yes, I get no umlauts in the generated image. The only font used is AvenirLT-Medium, which is embedded correctly (at least Adobe Acrobat tells me it is). The PDF hat been generated with Adobe Indesign. Left of the attached image is the output I get from the module, on the right site the PDF in Acrobat as reference.

Just queried Google and there might be a problem with either

  • ImageMagick
  • Ghostscript
  • Missing fonts
  • Wrong/false/incomplete embedded fonts
  • Other font issues

Or in short... if it's a server-related you might have to dig quite deep into it. From ImageMagick versions to installed Ghostscript fonts to (above mentioned) policy restrictions. Depending on your hosting or the client's hosting it might not even work. Shared hosting plans don't allow access to files and folders - but in most cases those environments are pretty well configured.

It might be easier to create a already pre-rendered first page for the PDF without any real text and fonts. Maybe converting them to paths or however it works in InDesign.

As it is only a download and nothing you'd push to a print shop, it should work out just fine.

Thanks for your quick reply! My problem is that the client generates the PDF himself, it contains a lot of pages and gets updated regularly. Our goal is to streamline his workflow by offering him to upload just one file and having the website generate thumbnails for all pages with hi-res previews as well. I will play around with Indesign's PDF export options and try wo solve the problem by converting the fonts to paths, but we do not want to loose the ability to search in the PDF. I will try to test it on the client's server as soon as possible, maybe the configuration there magically solves my problem 😉

After upgrading to the latest master 3.0.148 coming from the 3.0.123 version, this module stopped working in the sense that i am no longer able to upload files.

I get the following error message:

NOT AUTHORISED /files/assets/8888/filename.pdf @ error/constitute.c/ReadImage/412

I am still having issues with this module. this is what the error log shows running 3.0.148:

hello @Richard Jedlička, i found the issue. It was not an issue with the module but a problem with an ImageMagick-6 policy update on my Ubuntu machine, which seems to have happen around the same time as i updated my Processwire version:

The solution to my problem was to edit


than change the following line from:

<policy domain="coder" rights="none" pattern="PDF" />


<policy domain="coder" rights="read|write" pattern="PDF" />
and added the following line
<policy domain="coder" rights="read|write" pattern="LABEL" />

By changing the policy you have to make sure that you can trust the users that upload the pdf files.

Does fieldType PDF support tags? You can configure tags in the field set up but I get an error when I check for them with $pdf->getTag().

Edit: The field is fine, I made a mistake in how I was retrieving the tags, forgot that in order to get the tags as an array it should be $pdf->tags(true); and so the way I was doing it was the problem.

      This fieldtype and inputfield bundle was built for storing measurement values within a field, rendering them in a variety of formats and converting them to other units or otherwise modifying them via the API.
      The API consists of a number of predefined functions, some of which include...
      render() for rendering the measurement object, valueAs() for converting the value to another unit value, convertTo() for converting the whole measurement object to different units, and add() and subtract() for for modifying the stored value by the value (converted as required) in another measurement. In the admin the inputfield includes a checkbox (which can be optionally disabled) for converting values on page save. For an example if a value was typed in as centimeters, the unit was changed to metres, and the page saved with this checkbox selected, said value would be automatically converted so that e.g. 170 cm becomes 1.7 m.

      A simple length field using Fieldtype Measurement and Inputfield Measurement.
      Combination units (e.g. feet and inches) are also supported.
      Please note that this module is 'proof of concept' at the moment - there are limited units available and quite a lot of code tidying to do. More units will be added shortly.
      See the GitHub at https://github.com/MetaTunes/FieldtypeMeasurement for full details and updates.

      File Manager for ProcessWire is a module to manager files and folders from the CMS backend. It supports creating, deleting, renaming, packing, unpacking, uploading, downloading and editing of files and folders. The integrated code editor ACE supports highlighting of all common programming languages.

      This module is probably the most powerful module. You might destroy your processwire installation if you don't exactly know what you doing. Be careful and use it at your own risk!
      ACE code editor
      This module uses ACE code editor available from: https://github.com/ajaxorg/ace

      This module uses the JavaScript dragscroll available from: http://github.com/asvd/dragscroll. Dragscroll adds the ability to drag the table horizontally with the mouse pointer.
      PHP File Manager
      This module uses a modified version of PHP File Manager available from: https://github.com/alexantr/filemanager

      This module implements the website live chat service from tawk.to. Actually the module doesn't have to do much. It just need to inserted a few lines of JavaScript just before the closing body tag </body> on each side. However, the module offers additional options to display the widget only on certain pages.
      Create an account
      Visit https://www.tawk.to and create an account. It's free! At some point you will reach a page where you can copy the required JavaScript-code.

      Open the module settings and paste the JavaScript-code into the field as shown below. Click "Submit" and that's all.

      Open the module settings
      The settings for this module are located int the menu Modules=>Configure=>LiveChatTawkTo.

      Session Viewer is a module for ProcessWire to list session files and display session data. This module is helpful to display the session data of a specific session or to kick out a logged in user by simply delete his session file. After installation the module is available in the Setup menu.

      The following conditions must be met for the module to work properly:
      Session files
      Session data must be stored in session files, which is the default way in ProcessWire. Sessions stored in the database are not supported by this module. The path to the directory where the session files are stored must be declared in the ProcessWire configuration which is by default: site/assets/sessions.
      Serialize handler
      In order to transform session data easier back to a PHP array, the session data is stored serialized. PHP offers a way to declare a custom serialize handler. This module supports only the default serialize handlers: php, php_binary and php_serialize. WDDX was dropped in PHP 7.4.0 and is therefore not supported by this module as well as any other custom serialize handler. Which serialize handler is actually used you can find out in the module configuration which is available under Modules=>Configure=>SessionViewer.

      Session data
      The session data can be displayed in two different ways. PHP's default output for arrays print_r() or by default for this module nice_r() offered on github: https://github.com/uuf6429/nice_r. There is a setting in the module configuration if someone prefers print_r(). Apart from the better handling and overview of the folded session data the output of nice_r() looks indeed nicer.

      Repeater Easy Sort
      Adds a compact "easy-sort" mode to Repeater and Repeater Matrix, making those fields easier to sort when there are a large number of items.
      The module also enhances Repeater Matrix by allowing a colour to be set for each matrix type. This colour is used in the item headers and in the "add new" links, to help visually distinguish different matrix types in the inputfield.
      A Repeater field

      A Repeater Matrix field with custom header colours

      Easy-sort mode
      Each Repeater/Matrix item gets an double-arrow icon in the item header. Click this icon to enter easy-sort mode.
      While in easy-sort mode:
      The items will reduce in width so that more items can be shown on the screen at once. The minimum width is configurable in the field settings. Any items that were in an open state are collapsed, but when you exit easy-sort mode the previously open items will be reopened. You can drag an item left/right/up/down to sort it within the items. The item that you clicked the icon for is shown with a black background. This makes it easier to find the item you want to move in easy-sort mode. You can click an item header to open the item. An "Exit easy-sort mode" button appears at the bottom of the inputfield. Configuration
      In the field settings for Repeater and Repeater Matrix fields you can define a minimum width in pixels for items in easy-sort mode. While in easy-sort mode the items will be sized to neatly fill the available width on any screen size but will never be narrower than the width you set here.
      In the field settings for Repeater Matrix you can define a custom header colour for each matrix type using an HTML "color" type input. The default colour for this type of input is black, so when black is selected in the input it means that no custom colour will be applied to the header.
      The easy-sort mode is only possible on Repeater/Matrix fields that do not use the "item depth" option.
