GPT has really helped me with bash scripts and writing regular expressions, two very cryptic things that it handles extremely well. Love it.

How would I halt output of a template file using return $this->halt(); but with that code not actually appearing in the template file itself? In short, I want to halt output of a template file at some point using the halt method described, but I want to have it be done more flexibly, meaning I want that code to exist within my ready.php for example (or just somewhere not in the template file). What's the best way to do this? I don't want to use exit because it has unintended consequences.

@adrian Based on my approach above, which I'd like to keep, I additionally also want to enable TD development mode if I'm a guest and it matches my specific IP address. Is that possible? The way the allowedTracyUser method is written seems to suggest it is not.

That's correct. I oftentimes have non-developers set as the Superuser role, but I wouldn't want them to see the Tracy Debugger bar. Edit: I should reword my explanation as my usage of Development and Production is confusing within the context of Tracy Debugger.

I wanted to share the way I enable Tracy Debugger for myself (a superuser) and myself only, only when logged in. This is useful if there are other superusers that are not developers and you don't want them to see the Tracy Debugger bar. There's a variety of settings and methods related to this, but I wanted to distill it into a few short steps: create a permission called 'tracy-debugger' (note: Tracy Debugger doesn't create this permission for you during installation) create a role called 'developer' (sounds like the right name to me) assuming you're a superuser, edit your account and assign the 'developer' role; if there are multiple developers on the project, consider assigning them this role as well in Tracy Debugger's settings do the following: Main Setup → Output Mode → DEVELOPMENT Access Permission → Restrict Superusers → checked

I'm putting this here in case anyone finds this useful (or I google this myself in a few years)... Let's say you have the following in config.php: // config.php $config->myArray = [ 'foo' => [ 'k1' => 'v1', 'k2' => 'v2' ], 'bar' => 'some string', 'baz' => ['some', 'other', 'array'] ]; Now you want to want to add an item to the 'foo' array somewhere else in your codebase (template file, a module's init method, etc.). This won't work (overloaded notice will occur): $config->myArray['foo']['k3'] = 'v3'; Correct way to do it: $config->myArray = array_merge( $config->myArray, [ 'foo' => // existing $config->myArray['foo'] + // new [ 'k3' => 'v3' ] ] );

Is this happening on other PW installations on the same machine and separate/similar DDEV environment? Did you check apache error logs for anything suspicious?

There's no way to halt a template rendering from within my custom module's ready method? return $this->halt(); doesn't work 😞

This is an excellent idea and would simplify some of the gymnastics required when working with HTMX or similar libraries. I think this would fit nicely into how ProcessWire works.

How would I get a list of uninstalled/installable modules (or all modules whether installed or uninstalled)?

I have a URL hook like this which acts as an API endpoint: wire()->addHook('/foo/', function(HookEvent $event) { bd($event); }); That endpoint will be hit from somewhere with some post data, outside of ProcessWire. As you can see, I have a bardump to log $event, but I won't be able to see that output because it's coming from some outside request. How do I actually log it and store it (without using ProcessWire's own $log capabilities)?

I'm developing a very advanced ecommerce site with ProcessWire and an order needs to have various related pieces of data. To keep it simple for this example, an order should log payment attempts ('payment' template) and the items that were fulfilled ('fulfillment' template). Let's assume our order is here in the page tree, where 123 represents a page using the 'order' template (which contains the billing address and things like that): /orders/123/ One scenario that I often come across when developing ProcessWire sites with strong data relationships is where to put related pieces of data. In the situation I described, I could do it in one of three ways: Approach 1: as child pages of 'order' template I could make payments and fulfillments as children of the 'order' template. This is a ProcessWire-y way to do it. Approach 2: under one separate master page I could make payments and fulfillments as children of /order-updates/ and establish the relationship using an 'order' page reference field on the 'payment' and 'fulfillment' templates. This is a blend between traditional database design and a ProcessWire-y way to do it. Approach 3: under multiple master pages I could make payments as children of /payments/ and fulfillments as children of /fulfillments/ and establish the relationship using an 'order' page reference field on the 'payment' and 'fulfillment' templates. This is a traditional database design way to do it. What are your thoughts in regards to this specific example? Do any of them have pitfalls that I don't foresee? If I had to switch from one technique to another, that would be easy to do with a simple migration script.

I oftentimes create a checkbox field called 'test' and assign it to certain templates. I check the box if the page is a test page. These pages may exist on the live site and I don't want to hide or unpublish them, but at the same time, I don't want them to appear in the XML Sitemap. (not part of this tutorial, but I also noindex,nofollow those pages using a meta tag in the head so search engines don't index them) In that case, you can remove them from the WireSitemapXML like this in /site/ready.php: $wire->addHookAfter('WireSitemapXML::allowPage', function(HookEvent $event) { $page = $event->arguments('page'); if($page->hasField('test') && $page->test) $event->return = false; });

If accessibility and avoiding lawsuits matters, I'd avoid going that route. I spoke with a developer friend recently whose client got hit with an accessibility lawsuit. They then had a special accessibility firm audit and maintain the website. Sometime afterwards they got hit with 2 more accessibility lawsuits, although they were thrown out. This might be mainly a US phenomenon however... gotta keep those lawyers busy! UIkit pushed a big update today that (finally) addresses a lot of accessibility issues.

Thanks. To get the width and height of an image, I'm doing this: // within repeater loop that has a file field called 'project_file' $imageSizer = new ImageSizer($project_file->filename); $width = $imageSizer->getWidth(); $height = $imageSizer->getHeight();

I have a field that uses the Files fieldtype. Images and videos are being uploaded to it. Because it is not an Image fieldtype, I can't get an image width or height. I believe there is a way with the Pageimages class, but I'm a bit rusty on how to do this. There was a post on here that discussed how to do it but I can't find it. Any help would be appreciated.

I originally developed and launched Real SF Properties in 2015 and did a complete design and programming refresh in 2022: https://realsfproperties.com/ The site was designed by BuzzCandy.Design: http://buzzcandy.design/ This was my first time using Tailwind CSS and it was a great fit for this project. I wish it existed back in 2015 because while UIkit has been my go-to CSS framework for several years now, there are some site designs (and designers) that I work with that simply need a higher level of precision to slice correctly and be maintainable. Sure, I could have used vanilla CSS and done it the classic way (separation of concerns), but Tailwind CSS and doing everything with utility classes (locality of behavior) does come with major benefits, even if the markup is not so easy on the eyes. This site does not use a matrix page builder or anything fancy. The sections are hardcoded but with the ability to add data using the various page data structures that feed in accordingly. It has also has an accessibility score that is extremely high. It's a quick loading site even though ProCache or CDN is not yet enabled. Other frontend libraries include Flickity and Headroom.js. More details on my personal website: https://jonathanlahijani.com/projects/real-sf-properties/

Tracy's interface in the frontend seems to fall apart when using HTMX boosted links: https://htmx.org/docs/#boosting Has anyone had experience with this and know how to fix it?

I wanted to share this tip which I'm going to implement on Transferware Collectors Club Database. That site has a form which is a set of filters. It takes many queries to build that form and all of its options and as a result, it takes over 5 seconds to load the page. ProCache is out of the question because using a full page cache on a site like that doesn't make sense, but caching various areas with WireCache $cache does. The form is developed in a way where it will automatically populate/select the various form fields based on what it reads from the URL. So going to /?color=123 will automatically check the appropriate radio button for that color. Therefore, when using $cache to cache the form (or parts of the form), we need to cache the form in a clean, unpopulated state. The problem then becomes how do we use the cached form but also populate the fields accordingly based on the URL variables? Markup regions can do this. Assuming we had a set of radio options coming from our WireCache'd form like this: ... <input type="radio" name="color" id="color-123" value="123"> Red <input type="radio" name="color" id="color-124" value="124"> Blue ... We could devise some code that also outputs this on our page: <region pw-replace="color-123" checked></region> Markup regions will then "check" that radio. Perhaps this isn't mind blowing, but I've never thought of using Markup Regions in this way.

I should clarify that php 7.4.3 was fpm and php 8.1 was non-fpm. Not sure if php-fpm played a role.

OK I figured it out but don't know the exact reason. Upgrading from php 7.4.3 to php 8.1 resolved the issue. I noticed in 7.4.3, the http headers of the request are in lowercase, but in php 8.1, they are in the more proper case. Also, the headers are listed a little bit differently in 7.4 vs 8.1. That's probably where the issue is.

I'm getting the same 500 errors as well in my particular case. To clarify my situation: occurs on live site (Ubuntu 20.04, Apache 2.4.41, php 7.4.3), but not dev site (Ubuntu 22.04, Apache 2.4.52, php 8.1.2); i mirrored live to dev database as well enable live preview = on (not sse) While it 500 errors, the field technically does get autosaved (I can refresh the page without hitting the save button and the updated value is still there). I wonder if the Apache or PHP version matters. Will have to check. @adrian Did you ever find a solution to this?

Is it possible to set $config->sessionExpireSeconds for different users? What would be the best way to go about this?

If I remember correctly, there was a way to move the Users page to be somewhere else in the page tree. It involved changing some special settings. I can't seem to find it on the ProcessWire website. Does anyone remember the guide / blog post / whatever documentation was created for it?

While I'm not using it in real world project yet, the Combo field works well for a "link" field. For example, you could link something to a page (page field), a external website (url field) or a modal (page field), or a page + url parameters. Also, what about absolute vs relative URLs? Here's an export of that field you can import and play around with: https://pastebin.com/N8UuiFKQ Somewhat related is this module:
