  1. You can also use a conditional hook https://processwire.com/blog/posts/new-ajax-driven-inputs-conditional-hooks-template-family-settings-and-more/#new-conditional-hooks These fire only, when a specified field value has changed. So your potential problem of accidentally sending multiple emails can be eliminated. You just watch for changes in your status field and act accordingly. Edit: here is an excellent tutorial about how to watch for field changes: It uses a different hook.

  2. To be fair PHP 7.4 has only been out for a few weeks. I'm not advocating sticking with old versions for any longer than is necessary, but as with most software, going with the cutting edge version of PHP is a bit of a risky move. I'd recommend giving it a few more weeks at least ?

  3. Hi, here is what I used in last project for about 10 000 pages and and it is very simple and basic script. It's read csv file line by line and create pages, but to avoid execution time limits and to get some other options (eg. "pause" option and later "continue", real-time monitoring, etc.) I use very simple Ajax loop. Here is attachment and inside it is some "how-to" txt file. unzip-and-place-content-inside-templates.zip Please note that I use this for ~10 000 pages (in my case, processing time ~1s/page) and for more than that number you can try to do some optimisations and test it. There are few places for that. Teoretically it can works few days, but is it worth? ? Regards.

  4. I fork long running processes to the background. You don't need PCNTL functions for this. In an import module which takes some minutes to run, I have a file "importworker.php" <?php namespace ProcessWire; include(__DIR__ . "/../../../index.php"); // bootstrapping PW error_reporting(2); // setting error reporting // ini_set('max_execution_time', 300); // 300 seconds = 5 minutes wire('log')->save('productimport', "starting import: " . date('Y-m-d H:i:s')); $importModule = wire('modules')->get("ProcessImportProducts"); $importModule->importController('start'); wire('log')->save('productimport', "Import finished: " . date('Y-m-d H:i:s')); Then there is a method for forking the heavy work into the background public function startImportWorker() { $path = $this->config->paths->siteModules . "{$this->className}/"; $command = "php {$path}importworker.php"; $outputFile = "{$path}output.txt"; $pid = shell_exec(sprintf("%s > $outputFile 2>&1 & echo $!", $command)); return; } All output of the importworker script is piped to output.txt. So I can see what happens when the process is running in the background. Some methods in my module echo stuff so I can see it in output.txt. Also for longer running loops in my module, I use the ini_set('max_execution_time', 300) method to prolong execution time. And I unset variables along the way to take care of memory issues. With some ajaxy JS, I get the contents of output.txt and show them inside a div#status in my module, so the user knows that there is sth going on. var ProcessImportProducts = { init: function() { $('#startimport').on('click', function(e){ e.preventDefault(); $.get($(this).data('href'), function( data ) { // console.log(data); ProcessImportProducts.pollResults(0); }); }); }, pollResults: function(timestamp) { var statusUrl = '?getstatus=1'; var statusText = $('#status'); // var loader = $('.loader').clone(); if(!timestamp) statusText.html(''); $.ajax( { type: 'GET', dataType: 'json', url: statusUrl, success: function(data){ // console.log(data); // if file has changed append data to statusText if(timestamp != data.timestamp ) statusText.html(data.message).append('<div class="loader"></div>'); // call the function again, this time with the timestamp we just got from server var timeout = setTimeout(function() { ProcessImportProducts.pollResults(data.timestamp); }, 1000); if(data.timestamp == 0) { clearTimeout(timeout); $('.loader').addClass('hide'); } // scroll to bottom of status div statusText.scrollTop(statusText.prop("scrollHeight")); } } ); } }; $(document).ready(function() { ProcessImportProducts.init(); }); EDIT: heres the part of my ___execute() function, that returns the status stuff for the JS if($this->config->ajax) { if($this->input->start == 1){ $this->startImportWorker(); echo 1; return; } if($this->input->getstatus == 1) $this->returnStatus(); } else { // module output to screen } Here's a good read about running processes in the background: https://medium.com/async-php/multi-process-php-94a4e5a4be05 Hope that helps.

  5. Few things that are "nice to know" when building PW modules: Autoload and non-autoload modules: autoload ones are loaded on every page load. So if you need to hook into core, then you probably need autoload. Non-autoload modules are run only by request: $modules->get("myUberModule")->doSomething() When you need hooks? Well.. common things are "do something when page is saved", "alter the output that is generated", "do something before page is accessed" etc.. Actually there is quite a many hooks and best way to find right hook for you need is to ask for it here. Building modules is pretty similar to working with templates. Nothing "special" there. Few notes though: You cannot directly access the PW API variables like $pages, $session, $input etc.. Those are available at $this->pages or wire('pages'). If you have static method(s) in your modules then you need wire('pages') there - so if you want to play it safe always use that (it works on command line scripts also) Modules can have settings - those are very easy to implement (just look examples from other modules that have settings) Modules are cool. init() is run before page is loaded, so if your autoload module needs to know the current page, that is available at ready() method. Forums is your friend, just ask and someone (probably Soma with his quick editing skills) will surely help.
