Thanks man. There are different things to learn from this video. You have helped a soul. Composer usage in the plugin/ folder architecture and understanding how to use a library. 👏 I love it.
This is an excellent and very informative tutorial. It has provided me with a much better understanding of how to create a plugin. Thank you for your time and effort!
I don't get how having to install Carbon Fields lets you create a package that can be shipped. Doesn't it need to be installed wherever you put the plugin? When I simply installed the plugin in my wordpress, it failed because of the lack of the vendor folder/carbon fields.
Thank you, Mr. Digital. I am new at this. This tutorial is excellent and I am encouraged to learn and implement it. I followed the steps in the video very closely but I could not get past the ajax section (45 min marker) because I kept getting "Uncaught ReferenceError: jQuery is not defined"? Any idea how/where I can properly define jQuery.
@@MassinissaMouhoub-eg9pq , HI, I had to enqueue the jquery library. Also to make the javascript code work i had to wrap this into a setTimeout, like: setTimeout(() => { jQuery(document).ready(function ($) {
}); }). I am not sure if this is the best way but I didn't find any other solution.
for those having error "Uncaught ReferenceError: jQuery is not defined", just add ob_start and ob_get_clean on show_contact_form function. Code will look like this: function show_contact_form() { ob_start(); include MY_PLUGIN_PATH . '/includes/templates/contact-form.php'; return ob_get_clean(); }
Unless I'm mistaken, the purpose of the __construct is to pass initial parameter values back into the class. If that is true, why use the __construct to manage the plugin path for auto-loading classes?
This is great! More similar tutorials like this will be amazing, few ideas: Using ACF Interacting with external API Using react on FP & CSS Library (Tailwind?)
Hi! Your contents are awesome! You teach very clearly, I came from the last plugin dev series you've done, and I would say I learned a lot from that. If you're familiar with javascript frameworks, such as svelte, do you have a setup to use it to develop a Wordpress plugin? It would be a great series! Any frontend framework will doo
This is great... I do have 1 issue: register_rest_route callback is not working; I had a permission_callback error so i added __return_true. Getting a 404 in the return header. Any idea what I am doing wrong? Looking forward to continuing the lesson.
I wonder why u used Carbon Field instead ACF? You have many videos on ACF, since this is the latest video, I was wondering if you find carbon field more useful overall?

Hi. First of all, thank you for this. I am following this tutorial, installed Laragon. Everything was going smoothly but all of the sudden wordpress is not picking up the code from the folder? The front page is all blank and when i look at the source there's nothing. But my code still intact, no changes in the folder D:
Hey, thanks for the tutorial, my plugin is working so far. But I struggle with updating an existing submission. everything I tried always created a new submission instead of updating the old one - or it does not change save anything at all because I can't seem to get the correct post ID for the existing submission. Any idea?
Nevermind, I made it work. The title of a 'submission' is a unique userID. So I grab the existing post by using get_page_by_title that returns an object. This holds the correct post ID ('$postByTitle->ID'). Here's the snippet that works for me: $postByTitle = get_page_by_title( $params['userID'], 'OBJECT', 'submission'); foreach ($params as $label => $value) { update_post_meta ( $postByTitle->ID, $label, $value); }
Hello: I created your sample plugin. When I try to install I get Unpacking the package… Installing the plugin… The package could not be installed. No valid plugins were found. Plugin installation failed. This is the code:

Hey, I'm having some issues with verifying the nonce - it seems that it only verifies when I'm logged off, when I'm logged in it's not getting verified - Any ideas?

Hi Carina, go to your contact-form.php file and edit the "show_contact_form" function, can you change it to this and let me know if it works? function show_contact_form() { ob_start(); include MY_PLUGIN_PATH . '/includes/templates/contact-form.php'; return ob_get_clean(); }
somehow in my case JQuery wasn't working as in the video. So let me share what I did to fix it. (And... quite funny that in 2023 we are still using jQuery lol) symbol $ was generating some conflict so the first thing is add a "$ = jQuery.noConflict()" in the very first line of the form script. Then, you shall set "const form = $("#enquiry_form")" and work with the variable form all the time, it's possible that "$(this)" won't grab the form itself but the document. It happened to me because I was using arrow functions in stead of anonym function as in the video. And last, since the ajax action wasn't sending any data, PHP was thouing an error "_nonce key is not in array", so it may be a good idea to check first if the key is in the $params, and if is not, send a proper error warning, and not let PHP to send a debug error message.
Unfortunately, after watching this video after your five wordpress plugin from scratch series, as a beginner trying to learn developing plugins, this definitely wasn't simple. I got a lot from the security side of protecting the plugins. What happened to Part 6 and the end of the plugin from scratch? That was far easier to follow, probably as is was broken up a little more.
Great video, given you a sub and like ! Please make a another video on converting html website to Wordpress theme. Please let your html website have Author and authors page, tags page with each tag and its own post under, signup and signin page, membership page, comment section, single page, eror 404 page, archive page and more.

This ain't simple and maintainable at all as it requires carbon fields which is a rather complicated solution. Apart from that I wonder how an add-on using Composer can easily be shipped and installed into another WordPress.
@@michaelperlbach3438I agree that CF is not the easiest to use, the docs are hit-and-miss. The whole plugin vs library thing is confusing. Even the video is wrong, only carbon-fields needs to be installed the other is just a useless wrapper for it. I thought you meant that CF needs to be installed as WP plugin using Composer and that makes migrations difficult. But migration are easy as CF comes bundled into the plugin. I have had no issues with Composer.
@@kakosnaki You might have no problems with composer because you presumably have composer on your server and you have access to a shell. For hosting environments that do not provide for that this whole solution is useless.

Composer is just a package manager for PHP, keeps track of all the different php packages, their versions, updates etc

You can think of creating some custom action hooks.
