How to add CSS style sheet dynamically in wordpress
It seems like copy/paste gone wrong – both your variables point to same URL link and so file_exists() fails because it expects local path. Change $myStyleFile to local path and it should work.

Session is not starting
No, there’s no disadvantage to starting a session directly in your theme’s functions.php. However, it’s strange that starting your session on init is not working for you. Could it perhaps be that output is being generated (perhaps a space or a line break) before init? Could you turn WP_DEBUG on and see if any notices … Read more
WP_Cron doesn’t do the job: Multisite stats
It is set_site_transient, not set_site_site_transient. You should be aware that a single user will still wait that half a minute for this to complete. wp_cron does not run on clock time. It runs when a user visits the site. If you have the ability to create a system cron job then hook your callback to … Read more
How do you completely remove the default header and footer using functions.php?
The reason you’re not finding a quick fix is that there isn’t a consistent way to hide header and footer content across all templates, across all themes. Also, even builders like Elementor require the ability to enqueue their own CSS and JS. If you completely remove the header and footer, you will almost always also … Read more
Using email_exists() wp function in an ajax request
This happens because the PHP file you are using has no connection to WordPress, the function is never loaded. Use the built-in AJAX-API instead, and it will work fine.
Customising widget titles/headings in WP 5.8

How do I change parameters without changing the core
If you scroll further down the comment-template.php file, you’ll notice that the next available filter you can use is comment_form_defaults. With this filter you can change the default comment form configuration. add_filter( ‘comment_form_defaults’, ‘filter_comment_form_defaults’ ); function filter_comment_form_defaults( $defaults ) { $defaults[‘comment_field’] = sprintf( ‘<p class=”comment-form-comment”>%s %s</p>’, sprintf( ‘<label for=”comment”>%s</label>’, _x( ‘Please leave a comment…’, ‘Comment … Read more
Dequeue Scripts and Style for Mobile not working?
You should run the conditional tags (e.g. is_front_page()) from inside the callback/function (e.g. remove_default_stylesheet()) — see Where to Use Conditional Tags and the warning here. And there’s no hook named wp_enqueue_style; just use the wp_enqueue_scripts to enqueue/register/dequeue/deregister a stylesheet file. So I’m not sure the exact conditionals you need, but the following would dequeue/deregister the … Read more
Remove image from post_content on save_post
content_save_pre would be a much better hook for stripping the images, and as for setting post thumbnail as post Meta you can use save_post since the first hook gets fired before post Id is set and you need that for update_post_meta.
How do I properly register bootstrap JavaScript into WordPress functions.php?
As mentioned on the wp_register_script() codex page the handle: Should be unique as it is used as a handle for later use with wp_enqueue_script(). You are using the same handle for all your scripts, which won’t work. Besides that, if those scripts are depending on bootstrap, you have to at least register bootstrap before and … Read more
