Recommended Posts

@dotnetic  Yes as it looks, the browser seems to render the page correctly (I can't find any errors at least in "tracy" and in Chrome "DevTools").

My error that comes looks like this:

(first one = Chrome  // second one = Edge)

I've had this error sometimes and it was due to a broken pdf (don't know the reason). I don't understand why you want to use markup regions for rendering HTML of the pdf?? Are you trying to render a regular page HTML as PDF?? I don't think that's a good idea. In a regular HTML page you have lots of code that mPDF will at least not understand and in the worst case will break your pdf. So I'd recommend throwing custom HTML to mPDF instead of regular page markup. You'll have a lot more control over your pdf and a lot less troubles.

you misunderstood me then, i don't want to use markup regions to render html.
I just thought that because I use the template "Regular" and this is based on markup regions, it is probably because of that? Because the same code works for another project where I have chosen a direct output. See in this thread on page 2.

I will shown below my actual structure....

Are you trying to render a regular page HTML as PDF??

actual in my output-pdf.php File I have only this code

$pdf = $modules->get('RockPdf');
$pdf->set('SetHeader', 'This is my header text');
$pdf->write('Hello World ' . date('H:i:s'));
$pdf->write('<!-- my custom comment -->');
// Output
$pdf->show(); // to directly show your file in the browser

so I think if I understood the question correctly, the answer is no?

 

ok maybe it's easier if i just post my code to show what i'm trying to do


 

Spoiler

 

management.php
(with activated URL segments in the backend to the "management.php" template)


<?
// Login protection for this page by LoginRegisterPro
if($user->isLoggedin() != true) $session->redirect($config->urls->root.'user/', false);

// Checking the authorization to display the administration page
if($user->hasRole("editor") != true) $session->redirect($config->urls->root, false);

if(strlen($input->urlSegment2)) throw new Wire404Exception();

switch($input->urlSegment1) {
	case '':

		// Output to the content-body ?>
		<div id='content-body'>


			<? // The following code will later control the content that will appear on the PDF ?>

			Please select an entry:<br>
			<form class="uk-form-stacked" action="<?=$page->url;?>pdf/" target='_new' method="post">
				<input type="hidden" name="check" value="PDFdruck">
				<div class="uk-margin">
					<div class="uk-form-controls">
						<select class="uk-select" id="form-stacked-select" name="assignment"><?
							foreach($pages->find("template=lesson, date_from<=today, sort=-date_from, sort=-date_time") as $lessonID){
								echo"<option value='". $lessonID->id ."'>". $lessonID->date_from ." ". $lessonID->date_time ." clock</option>";
							} ?>
						</select>
					</div>
				</div>
				<input type="submit" class="uk-button uk-button-secondary uk-button-small" value="Output status as PDF">
			</form>

		</div>
		<!-- content-body -->

		<?

	break;

	case 'pdf':
		// Display PDF in Browser
		include 'pdf.php';

	break;

	default:
		// Anything else? Throw a 404
		throw new Wire404Exception();
}

?>

 

actual for testing (but even that unfortunately does not work...)

pdf.php


<?
/**
 * Outputs a PDF for independent printing
 * Version 2021-02-xx
 */


// Code for the creation of a PDF
$pdf = $modules->get('RockPdf');
$pdf->set('SetHeader', 'This is my header text');

$pdf->write('Hello World ' . date('H:i:s'));
$pdf->write('<!-- my custom comment -->');

// Output
$pdf->show(); // to directly show your file in the browser

?>

And that's it, with these specifications come the errors from above....

I'd suggest the following:

First, disable markup regions to confirm that it works when markup regions are disabled. Then enable markup regions and to this:

// replace this
include 'pdf.php';

// by that:
echo "include PDF here";

Then load your page that should create the PDF and inspect the HTML (right click -> show sourcecode). What does the source code look like?

Your example pdf.php looks absolutely fine. Please try to save the PDF file via $pdf->save() or $pdf->download() and then take a look if the PDF is generated.

@dotnetic

I have tried and the result is that 
$pdf->show() => does not work
$pdf->download() => does not work
$pdf->save() => works, puts the correctly generated PDF on the server

so it seems to be rather a problem with the output method "markup regions" which I use, respectively that I still have a wrong code structure here or?

Thanks bernhard, I went through the points one by one
1. I deactivate markup regions in config.php => output in browser works now! (However, the design no longer fits)

2a. I enable markup regions again and test the change from above (I'm not quite sure now if I should really just put the "echo" in the "case 'pdf': "? I do it, and it outputs my design (up to the header, then a white body, and the footer again at the bottom). The only thing it outputs to me at the bottom of the pw-region-debug line is "No regions" and the time of generation, nothing else.

2b. I interpret your echo to mean that I should paste the code from my pdf.php file here instead of the include command. Unfortunately the result is again the same as above with dotnetic's suggestion. The only code that works to create a PDF is save().

3. "... what does the source code look like?" => Unfortunately there is no real HTML code to look at or parse (except for the one in point 2a, but there it doesn't process anything....) so I can't share anything.

Sorry if I'm a bit clumsy here.... I am therefore very grateful for any help.

Hi @bernhard "rockpdf" works just fine for my needs but I still have two little problems:

1. I already have a little form with takes a few inputs (text values) which get nicely saved too when the pdf is generated and saved with "rockpdf" on the server sending me an email. I only do not know how to attach the output.pdf before submitting the email form. May you can help?

2. Not so important right know for me but I also realized "$pdf->show() => does not work"  like @Ralf mentioned just above does not work for me either on a very minimal example.

Thanks @bernhard for the link but there is still a problem for me, because:

1. If use the examples of the provided link it works fine for sending an email with $m->... but I do not know how to save the pdf this way and therefore no pdf-file is attached

  If I use something like $pdf->save() I get a failure which tells me "... not allowed in this context ..."

2. Could may provided just very basic example code how that

$pdf->... in your module works together with $m->... you provided in the link above?

All I need would be: A pdf created by RockPdf which gets send as an attachment by $m->... (the link you provided ... )

It's all in the docs:

save.png

Then simply use the path of the pdf as path of the attachment:

$file = $pdf->save();

$mail = new WireMail();
...
$mail->attachment($file->path);
$mail->send();

Hi to everybody!

I found this useful module and it works fine on desktop (either pc and mac, Chrome/Safari/Opera/FireFox/Vivaldi and IE), but sometimes I've encountered different behaviours on mobile (tested on Android and iOs, with Chrome, Firefox, Opera, and Safari).

Briefly, I built an html table in delayed output (a race ranking, one for each different race pages), I collect it into a variable and passed it throug a $_SESSION index to another page where it's grabbed with a ob_start()/ob_get_contents()/ob_end_clean() statement (no echos are present out of this one ob_start/ob_end).

Despite the desktop pdf output it's ok (I can show()/save()/download() the files and open them with Acrobat, and into docs properties I found each custom setting, e.g. title, author, application and so on) on mobile, instead, I encountered two kind of issues:

1) Most of  times, in Chrome, I was alerted of a non valid file, or FireFox it's not able to save pdf file.
2) Some times the file is outputted also on mobile and it's perfectly readble, but on save and on open by Acrobat App I found the content empty with the notice of the $_SESSION['nameofindex'] undefined.

N.B. Same results also calling directly mPdf after RockPdf and setting it's proper methods.
No problems with a "static" html code passed to the write() method, but I'm getting crazy figuring why it works fine on desktop and not on mobile (or it's ok also on mobile, but can't save a correct file) with $_SESSION.

Does anyone encontered same kinds of these strange behaviours?

Any suggestion about that?

 

Many thanks in advance.

Thx @axelino and welcome to the forum 🙂 

I tried to test the library quickly but could not make it work. Could you please provide a PR and usage instructions for the readme so that I can check it quickly? Then I'm happy to add it to the module 🙂 

Hello @bernhard, sorry it took a little longer but I just submitted the Pull-Request.
Please take a look at it and let me know if further adjustments or info is needed.

Thank you! 🙂

I just want to have a simple "download this page as pdf" button on my page.

Why not just use the browser features with @media print in the css?

What browser feature do you mean?

      Symprowire is a PHP MVC Framework based and built on Symfony using ProcessWire 3.x as DBAL and Service-Provider
      It acts as a Drop-In Replacement Module to handle the Request/Response outside the ProcessWire Admin. Even tough Symfony or any other mature MVC Framework could be intimidating at first, Symprowire tries to abstract Configuration and Symfony Internals away as much as possible to give you a quick start and lift the heavy work for you.
      The main Goal is to give an easy path to follow an MVC Approach during development with ProcessWire and open up the available eco-system.
      You can find the GitHub Repo and more Information here: https://github.com/Luis85/symprowire
      Documentation
      The Symprowire Wiki https://github.com/Luis85/symprowire/wiki How to create a simple Blog with Symprowire https://github.com/Luis85/symprowire/wiki/Symprowire-Blog-Tutorial Last Update
      16.07.2021 // RC 1 v0.6.0 centralized ProcessWire access trough out the Application by wrapping to a Service https://github.com/Luis85/symprowire/releases/tag/v0.6.0-rc-1 Requirements
      PHP ^7.4 Fresh ProcessWire ^3.0.181 with a Blank Profile Composer 2 (v1 should work, not recommended) The usual Symfony Requirements Features
      Twig Dependency Injection Monolog for Symprowire Support for .env YAML Configuration Symfony Console and Console Commands Symfony Webprofiler Full ProcessWire access inside your Controller and Services Webpack Encore support Caveats
      Symfony is no small Framework and will come with a price in terms of Memory Usage and added Overhead. To give you a taste I installed Tracy Debugger alongside to compare ProcessWire profiling with the included Symfony Webprofiler

      So in a fresh install Symprowire would atleast add another 2MB of Memory usage and around 40ms in response time, should be less in production due to the added overhead of the Webprofiler in dev env

      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 Fluency is free, and now so is DeepL
      Since this module was first built DeepL has introduced free Developer accounts that allow anyone to start using Fluency at zero cost and beginning with the version 0.3.0 release Fluency now supports free DeepL accounts. As of June 2021 DeepL supports translation to 26 languages and continues to offer more!
      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. Fluency can be used by users having roles given the fluency-translate 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 Github 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 Github 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.
      The Module Is 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).
      DeepL Developer Accounts
      In addition to paid Pro Developer accounts, DeepL now offers no-cost free accounts. Now all ProcessWire developers and users can use Fluency at no cost.
      Learn more about free and paid accounts by visiting the DeepL website. Sign up for a Developer account, get an API key, and start using Fluency today.

      PageViewStatistic for ProcessWire is a module to log page visits of the CMS. The records including some basic information like IP-address, browser, operating system, requested page and originate page. Please note that this module doesn't claim to be the best or most accurate.
      Advantages
      One of the biggest advantage is that this module doesn't require any external service like Google Analytics or similar. You don't have to modify your templates either. There is also no Javascript or image required.
      Disadvantages
      There is only one disadvantage. This module doesn't record visits if the browser loads the page from its browser cache. To prevent the browser from loading the page from its cache, add the following meta tags to the header of your page:
      <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> How to use
      The records can be accessed via the Setup-menu of the CMS backend. The first dropdown control changes the view mode.

      Detailed records
      View mode "Detailed records" shows all visits of the selected day individually with IP-address, browser, operating system, requested page and originate page. Click the update button to see new added records.

      Cached visitor records
      View modes other than "Detailed records" are cached visitor counts which will be collected on a daily basis from the detailed records. This procedure ensures a faster display even with a large number of data records. Another advantage is that the detailed records can be deleted while the cache remains. The cache can be updated manually or automatically in a specified time period. Multiple visits from the same IP address on the same day are counted as a single visitor.

      Upgrade from older versions
      Cached visitor counts is new in version 1.0.8. If you just upgraded from an older version you might expire a delay or even an error 500 if you display cached visitor counts. The reason for this is that the cache has to be created from the records. This can take longer if your database contains many records. Sometimes it might hit the maximally execution time. Don't worry about that and keep reloading the page until the cache is completely created.
      Special Feature
      PageViewStatistic for ProcessWire can record the time a visitor viewed the page. This feature is deactivated by default. To activate open the module configuration page and activate "Record view time". If activated you will find a new column "S." in the records which means the time of view in seconds. With every page request, a Javascript code is inserted directly after the <body> tag. Every time the visitor switches to another tab or closes the tab, this script reports the number of seconds the tab was visible. The initial page request is recorded only as a hyphen (-).

      New in version 1.1.0
      A new feature comes with version 1.1.0 which offers to record user names of loggedin visitors. Just activate "Record user names" and "Record loggedin user" in the module settings.
      Settings
      You can access the module settings by clicking the Configuration button at the bottom of the records page. The settings page is also available in the menu: Modules->Configure->ProcessPageViewStat.
      IP2Location
      This module uses the IP2Location database from: http://www.ip2location.com. This database is required to obtain the country from the IP address. IP2Location updates this database at the begin of every month. The settings of ProcessPageViewStat offers the ability to automatically download the database monthly. Please note, that automatically download will not work if your webspace doesn't allow allow_url_fopen.
      Dragscroll
      This module uses DragScroll. A JavaScript available from: http://github.com/asvd/dragscroll. Dragscroll adds the ability in view mode "Day" to drag the records horizontally with the mouse pointer.
      parseUserAgentStringClass
      This module uses the PHP class parseUserAgentStringClass available from: http://www.toms-world.org/blog/parseuseragentstring/. This class is required to filter out the browser type and operating system from the server request.

      Inertia Adapter ProcessWire Module
      Hello! Long time no see.
      I created this module so you can use Inertia.js (https://inertiajs.com/) with ProcessWire.
      Description
      Inertia allows you to create fully client-side rendered, single-page apps, without much of the complexity that comes with modern SPAs. It does this by leveraging existing server-side frameworks.
      Inertia isn’t a framework, nor is it a replacement to your existing server-side or client-side frameworks. Rather, it’s designed to work with them. Think of Inertia as glue that connects the two. Inertia comes with three official client-side adapters (React, Vue, and Svelte).
      This is an adapter for ProcessWire. Inertia replaces PHP views altogether by returning JavaScript components from controller actions. Those components can be built with your frontend framework of choice.

      Hi all,
      we made a small module for sending SMS via Sms77.io. It supports sending to one and multiple users.
      You can download it from GitHub and follow the instructions on how to install it - it is quite easy. An API key is required for sending, get yours for free @ Sms77 and receive 0,50 €.
      Hope this helps somebody and we are open for improvement suggestions!
       
      Best regards
      André
