Hi, new version is here, as I promised. It's currently on the dev branch: https://github.com/uiii/ProcessWire-FieldtypePDF/tree/dev. The readme is updated so everything should be clear. It contains tests and they successfully passed for PW 2.4, 2.5. If you can try the module, I'd be glad to hear your opinions and suggestions.

Oh yeah, my hosting provider said they couldn't update GS to 9.x...

Thanks for the update - will check it out as soon as I can. :)

I'm trying this (dev) on PW 2.6 and it works fine so far but I'm not sure why it's using Image field ... like it has the pdf file but showing an image that in PW 2.6 has a dialog for cropping etc. The file basename is a link that opens a modal where there's an error:

When creating the PDF field I'm seeing configurations same like an image field, but it's not. I'm not sure this is the right direction of how this should work.

Because I'm not able to download/open the PDF itself in the admin like I expect when clicking on the basename. Maybe I get it wrong, but it's not only about creating an image of a pdf but also having the pdf itself. So there maybe the best way is to introduce your own "renderItem()" method again instead of using the parent method.

Hi, thanks for the reply. I haven't tried the PW 2.6 yet. The reason why I used image inputfield is to render the PDF thumbnails exactly the same way as images. But maybe you are right, I should have used my own render method. I'll check it out.

DEV branch is updated, should be PW 2.6 compatible now. And InputfieldImage is not parent of InputfieldPDF anymore. Check it out.

Not sure why this worked, but I had to modify the ImageMagick code in PagePDF.php a bit to get it working on GoDaddy shared hosting (I know, I know...):

$imagick = new Imagick($this->filename . "[0]");
$imagick->setResolution(300, 300);
$imagick->setOption('pdf:use-cropbox', 'true');
//$imagick->setColorspace(Imagick::COLORSPACE_RGB);
//$imagick->readimage($this->filename . "[0]");
$imagick->setImageFormat('png');
$imagick->scaleImage($width, $height);
$imagick->writeImage($filename);

I believe it has to do with GoDaddy running old versions of IM and GhostScript, but I'm not certain.

Hi @evan,
yes, it's probably because of the old version of IM and GS. What was the problem exactly (error message, ...), can you post it here? I also find that setColorspace method is supported since IM version 6.5.7, so I should change the code to reflect that. What is the problem with readImage method? Will it work if you comment only setColorspace?

It's been a while since I did this, but I think you will have problems with the change to loading the image at the start rather than using readImage. The problem is with setResolution - this needs to happen before the image is read. The image is rasterized as soon as it is read, so setting the resolution afterwards can result in a poorer quality image.

The setColorspace() method doesn't exist on my server, as IM is too old (ImageMagick 6.5.4-7):

Error: 	Call to undefined method Imagick::setColorspace() (line 16 of /path/to/public_html/site/modules/FieldtypePDF/PagePDF.php)

When I use readFile(), I get the following error (not the real path, obviously):

- Postscript delegate failed `/path/to/file.pdf': No such file or directory @ pdf.c/ReadPDFImage/611

From what I read this is common if you're using a pre-9.x version of GhostScript (server has 8.70).

I haven't seen any visible quality issues with declaring the image with the Imagick object, but I also haven't been looking too carefully -- mostly glad to get it working at all.

Hi, I've been doing some research and testing. But I don't find a way to get it properly working on older versions of ghostscript. But @evan's solution works, it produces low quality images and it's properties cannot be affected because the pdf is read on the Imagick object creating. The readImage method always throws the mentioned exception. Despite of this it is useful where you cannot update GS or IM (e.g. shared hosting). So I added it to the module as fallback mode. It can be turned on in the module's settings. See DEV branch.

Any chance to update this module for 2.5+? Aka making the dev to the new master?

Hi, sorry I din't do that yet. I stucked, because I wanted to test it properly first. I wanted to make automated unit tests, but in processwire it isn't (maybe wasn't) so easy, I wanted to use wireshell to help with it, but somehow I moved my activity somewhere else. I can merge the branches, but I would like to have some feedback if it is working correctly or not. Did you try it? I've tried it in PW 2.5 and 2.6 and it looks it's working, but I'm not sure about PW 2.7+. If you can test it a give me feedback I would appreciate it. Thanks

Hi Richard,

I've tried out this module on version 2.6 and it works nicely! 

I've tried installing it in version 3.0 and had to restore the database from backup: I got error messages and couldn't reach the PDF-field anymore. 

The information about compatibility is misleading: on the module page it says compatible with version 3.0, but later on it's stated <3.0.

Too bad I can't used it now, I liked it a lot!

Thanks.

Hi lenoir,

There is a version compatible with 3.0, it is in devns branch, it is separated because i didn't find a way to have one codebase compatible with PW 2.x and 3.x (I can tell you more if you want).

What happend with your pdf files in 3.0? Why did you have to restore the database? Should I fix something?

Cheers,
Richard

Finally I've found out how to support PW 2.x and PW 3.x with one codebase. So here is a new version 1.1.2 compatible with PW 2.5+. I updated the tests as well, turned the script which runs tests against multiple versions of ProcessWire into standalone tool PW-Test.

@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

      This module is (yet another) way for implementing a cookie management solution.
      Of course there are several other possibilities:
      - https://processwire.com/talk/topic/22920-klaro-cookie-consent-manager/
      - https://github.com/webmanufaktur/CookieManagementBanner
      - https://github.com/johannesdachsel/cookiemonster
      - https://www.oiljs.org/
      - ... and so on ...
      In this module you can configure which kind of cookie categories you want to manage:

      You can also enable the support for respecting the Do-Not-Track (DNT) header to don't annoy users, who already decided for all their browsing experience.
      Currently there are four possible cookie groups:
      - Necessary (always enabled)
      - Statistics
      - Marketing
      - External Media
      All groups can be renamed, so feel free to use other cookie group names. I just haven't found a way to implement a "repeater like" field as configurable module field ...
      When you want to load specific scripts ( like Google Analytics, Google Maps, ...) only after the user's content to this specific category of cookies, just use the following script syntax:
      <script type="text/plain" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The type has to be "optin" to get recognized by PrivacyWire, the data-attributes are giving hints, how the script shall be loaded, if the data-category is within the cookie consents of the user. These scripts are loaded asynchronously after the user made the decision.
      If you want to give the users the possibility to change their consent, you can use the following Textformatter:
      [[privacywire-choose-cookies]] It's planned to add also other Textformatters to opt-out of specific cookie groups or delete the whole consent cookie.
      You can also add a custom link to output the banner again with a link / button with following class:
      <a href="#" class="privacywire-show-options">Show Cookie Options</a> <button class="privacywire-show-options">Show Cookie Options</button> This module is still in development, but we already use it on several production websites.
      You find it here: PrivacyWire Git Repo
      Download as .zip
      I would love to hear your feedback 🙂
      CHANGELOG
      0.1.1 Debugging: fixed error during uninstall 0.1.0 Added new detection of async scripts for W3C Validation 0.0.6 CSS-Debugging for hiding unused buttons, added ProCache support for the JavaScript tag 0.0.5 Multi-language support included completely (also in TextFormatter). Added possibility to async load other assets (e.g. <img type="optin" data-category="marketing" data-src="https://via.placeholder.com/300x300">) 0.0.4 Added possibility to add an imprint link to the banner 0.0.3 Multi-language support for module config (still in development) 0.0.2 First release 0.0.1 Early development

      Hi all,
      I have need to dynamically set InputFieldMultiSelect to  selected on page load based on the status of some items within a database table.
      However I keep running into issues when trying to do this via InputfieldSelect::setOptionAttributes()
      https://processwire.com/api/ref/inputfield-select/set-option-attributes/
      Going by the above it sounds like it should be pretty straight forward, and for certain values it seems to work but not when I wanted to set it to 'selected'.
      For example:
      $f->setOptionAttributes(1030,['foo' => 'test']); The above works as I would have wanted, in that it updates the option with the value 1030, to include the attribute foo="test"
      But the same code above edited to the following:
      $f->setOptionAttributes(1030,['selected' => 'selected']); Doesn't seem to do anything?
      I assume I'm missing something or trying to implement the 'selected' wrongly but I'm not sure how else I should approach this, any advice would be much appreciated.

      Cacheable Placeholders
      This module allows you to have pieces of dynamic content inside cached output. This aims to solve the common problem of having a mostly cacheable site, but with pieces of dynamic output here and there.  Consider this simple example, where you want to output a custom greeting to the current user:
      <h1>Good morning, <?= ucfirst($user->name) ?></h1> This snippet means you can't use the template cache (at least for logged-in users), because each user has a different name. Even if 99% of your output is static, you can only cache the pieces that you know won't include this personal greeting. A more common example would be CSRF tokens for HTML forms - those need to be unique by definition, so you can't cache the form wholesale.
      This module solves this problem by introducing cacheable placeholders - small placeholder tokens that get replaced during every request. The replacement is done inside a Page::render hook so it runs during every request, even if the response is served from the template cache. So you can use something like this:
      <h1>Good morning, {{{greeting}}}</h1> Replacement tokens are defined with a callback function that produces the appropriate output and added to the module through a simple hook:
      // site/ready.php wire()->addHookAfter('CachePlaceholders::getTokens', function (HookEvent $e) { $tokens = $e->return; $tokens['greeting'] = [ 'callback' => function (array $tokenData) { return ucfirst(wire('user')->name); } ]; $e->return = $tokens; }); Tokens can also include parameters that are parsed and passed to the callback function. There are more fully annotated examples and step-by-step instructions in the README on Github!
      Features
      A simple and fast token parser that calls the appropriate callback and runs automatically. Tokens may include multiple named or positional parameters, as well as multi-value parameters. A manual mode that allows you to replace tokens in custom pieces of cached content (useful if you're using the $cache API). Some built-in tokens for common use-cases: CSRF-Tokens, replacing values from superglobals and producing random hexadecimal strings. The token format is completely customizable, all delimiters can be changed to avoid collisions with existing tag parsers or template languages. Links
      Github Repository & documentation Module directory (pending approval) If you are interested in learning more, the README is very extensive, with more usage examples, code samples and usage instructions!
