How do I deregister style sheet from wordpress using functions.php? - wordpress

I found this article here on how to deregister styles in wordpress. techotronic.de/how-to-de-register-style-sheet-wordpress/
Pretty simples I thought but I can't get my head round what he's trying to say. This is the code below...
add_action( 'wp_print_styles', 'custom_deregister_styles', 100 );
function custom_deregister_styles() {
wp_deregister_style( 'colorbox-theme1' );
}
Straight forward enough, for his plugin...
But if I wanted to deregister a style from another plugin I'm using, how do you find out what name to put in the code - wp_deregister_style( ' ???? ' );
I've tried the obvious, the stylesheet name...
add_action( 'wp_print_styles', 'custom_deregister_styles', 100 );
function custom_deregister_styles() {
wp_deregister_style( 'language-selector.css' );
}
and this is another method I found, but can't get my head around what I got to do?
add_action("gform_enqueue_scripts", "deregister_style");
function deregister_style(){
wp_deregister_style("gforms_css");
}
How does this deregister method work, and what do I need to look for in the plugin to get the relative name to get it to work. I'm very confused.
Appreciate any advice thanks!
UPDATE
I have just discovered the style sheet I'm trying to deregister is not loaded via wp_enqueue_style or wp_register_style.
See php file from plugin here https://gist.github.com/1442470
And look on Line 792 for language-selector.css

Find wp_register_style or wp_enqueue_style in the plugin folder. You'll find the name in that function call.
Update: You cannot remove this without editing the plugin, or resolving to ugly hacks like buffering all the output and filtering it at the end. That's the reason wp_enqueue_style or wp_register_style should be used for all stylesheets.

Wordpress, what is the easiest way to block extern stylesheet?

I'm currentry trying to switch from extern fontawesome to local. I implemented the local fontawesome, but I can't find a solution to blocklist the extern stylesheets, which are added by Plugins.
I tried to find the handle of the stylesheet enqueue. Couldn't find the handle and it wouldn't make much sense, since many plugins could be importing fontawesome
You can use the wp_print_styles action hook that is triggered before stylesheets are printed to the page. Try adding this code to your theme's functions.php file:
function remove_plugin_stylesheet() {
wp_deregister_style( 'style-handle' );
wp_dequeue_style( 'style-handle' );
}
add_action( 'wp_print_styles', 'remove_plugin_stylesheet', 100 );
Also, don't forget to replace the 'style-handle' parameter with the actual ID of the stylesheet you want to remove. Feel free to refer to this example in case you can't find it → https://prnt.sc/fXo-J1UiCLwY

Problem with the media library in wordpress

I am building my own wordpress theme and I have such a problem. Media library doesn't work, I can't add any image to the page. I am using the latest version of wordpress.
Files available on github https://github.com/krysba/themes-wordpress
When I turn on the standard wordpress theme, the library works :(
I am asking for help in solving this problem.
If you have not tried, the first thing that i'll tring it's enable debug mode on Wordpress from wp-config.php and check if some alerts or errors can help.
define('WP_DEBUG', true);
I think that you must try to comment all function.php and debugging it row by row.
At the first check i've found a wrong use of the function add_theme_support and in the enqeueing files.
For example the right way to user add_theme_support is on the after_setup_theme action:
function my_setup_theme(){
add_theme_support('post-formats',array('gallery','link','image','quote','status','video','audio'));
}
add_action( 'after_setup_theme', 'my_setup_theme' );
Also the right way to enqueing scripts or styles is that:
function add_theme_scripts() {
wp_enqueue_style( 'style', get_stylesheet_uri() );
}
add_action( 'wp_enqueue_scripts', 'add_theme_scripts' );

How can I override or remove a plugin's CSS from my wordpress page?

Though I can certainly delete the files or references to them in the plugin code, this is not futureproof when I made plugin updates. They say that if I create a copy of their frontend.css file in my {theme}/{pluginname}/css folder, it will override theirs, but that doesn't work.
So I'm left with a style that takes priority because it matches on one of their containers and overrides my default page links.
For example:
.somecontainer a {
color:red
}
I need it gone. Preferably in a way that doesn't use !important or me specifying another instance of the same to override the values because then I have to manage the colors and styles in my original CSS AND in the override.
I already found code to print all enqueued styles and there were none so I can't just unqueue it.
The answer was apparently to DEqueue their styles at the same time I enqueued mine. Not sure why... seems like that would create problems, but this worked:
function my_style() {
wp_dequeue_style( 'pmpro_frontend' );
wp_dequeue_style( 'pmpro_print' );
wp_enqueue_style( 'my-style', get_bloginfo('stylesheet_url') );
}
add_action('wp_enqueue_scripts', 'my_style', 11 );
First you'll need to identify the names/handles that the plugin's stylesheets were originally enqueued under. You can do this
quickly by running a search on your web server in the plugin's
directory, e.g. grep wp_enqueue_style /var/www/mysite/wp-content/plugins/nameofplugin/
Then add a dequeue function to the functions.php file,
and invoke it on the wp_enqueue_scripts with a priority higher than the
priority level set on the plugin's original enqueue function.
function remove_plugin_styles() {
wp_dequeue_style( 'name_of_plugin_stylesheet' );
wp_dequeue_style( 'name_of_plugin_stylesheet_2' );
}
add_action( 'wp_enqueue_scripts', 'remove_plugin_styles', 99 );

wp_enqueue_style not loading CSS

I am attempting to load a script using wp_enqueue_style following the advice on the Wordpres Codex, but the script doesn't seem to be included in the source. Is this the correct way to do it?
function load_scripts() {
wp_enqueue_style('bootstrap.css', get_template_directory_uri() . '/css/bootstrap.min.css');
}
add_action('wp_enqueue_scripts', 'load_scripts');
Your action and function looks fine from here. The wp_enqueue_scripts hook should work perfectly for both stylesheets and scripts.
Have you tried echoing something out in the function to see if it's actually being called at all? I.e:
function load_scripts() {
echo "Does this output to the actual page?";
wp_enqueue_style('bootstrap.css', get_template_directory_uri() . '/css/bootstrap.min.css');
}
add_action('wp_enqueue_scripts', 'load_scripts');
If it's not, you might have a problem with your placement of the code, but if you keep everything in functions.php and outside of any other scope this shouldn't be a problem.
Another thing that can cause this behaviour is if you have already registered a stylesheet or script with the same handle ("bootstrap.css" in this case). The first argument in the wp_enqueue_style() function is just a handle for internal dependency management and should be unique, try renaming it to something else and see if that fixes your problem.
Okay, first step is to ensure you are using the correct path of the CSS file.
Add the following line in the functions.php of your theme or other appropriate place.
print( get_template_directory_uri() . '/css/bootstrap.min.css' );
This should print the URL of your desired stylesheet on top of the page. Copy and paste this URL in a new tab, if it opens a stylesheet then you are good to go. Otherwise, there is a mistake in the path.
Second step is to ensure that wp_head() is being called on the page you are displaying. It can be placed in your header template or top of archives/post files etc. This function actually renders the styles and scripts on the page.
Without wp_head(), its basically useless to enque anything as you can add links and scripts manually if you know the exact paths.
Note that in admin mode there is a special hook 'admin_enqueue_scripts'. So, if there is need to load CSS in both modes, it should be done on two hooks.
function load_scripts() {
wp_enqueue_style('bootstrap.css', get_template_directory_uri() . '/css/bootstrap.min.css');
}
add_action('wp_enqueue_scripts', 'load_scripts');
add_action('admin_enqueue_scripts', 'load_scripts');
You are trying to enqueue style on wp_enqueue_scripts hook.
Try wp_print_styles.
add_action('wp_print_styles', 'load_scripts');
Also try to register style, first.
in case you don't want to use wp_head(); in your template, you could also include your styles directly:
<link rel="stylesheet" href="<?php echo get_theme_file_uri( 'style.css' ); ?>">
beware though: wp_head() includes tons of stuff (scripts, styles,...), by wordpress itself as well as most plugins, so only omit it if you know what you're doing.
Register the style first:
function register_plugin_styles() {
wp_register_style('my-plugin', plugins_url('my-plugin/css/plugin.css'));
wp_enqueue_style('my-plugin');
}
http://codex.wordpress.org/Function_Reference/wp_register_style
Do that way. Dont try to enqueue directly. And put code into functions.php of course.
Fist confirm path of the css file is correct or not if is it a correct try with below code :
function load_scripts() {
wp_enqueue_style('load-custom-css-new', get_template_directory_uri() . '/css/bootstrap.min.css');
}
add_action('wp_enqueue_scripts', 'load_scripts');
or Go with this URL.

I had the same problem. Although I have implemented this many times before, I lost many hours to find out what went wrong with this.
Because I made my own themes, I had declared this file unit as “fuctions.php” (I lost the -n- letter).
So, besides all the things described above you should also consider, take a good look at the file name and confirm that is “functions.php” (not fuctions, not function etc).
This might be also the reason for you.
I had the same issue. I fixed it by hard refreshing the page with Ctrl + F5 to clear cache and the css loaded normally.
If you are protecting the directory with .htpasswd, the https call generated by get_stylesheet... will fail, and you might lose some time chasing that one.

wordpress can't dequeue script/style that has query

Not sure if I worded it correctly but basically I wanted to load plugin CSS/JS on pages only that uses the actual plugins.. I have gotten a lot of it done by search thru the plugin files for any handles used in wp_enqueue_script within the plugins and simply wp_dequeue_script them in functions.php
However, there are some enqueues for style that include a .php and not a css file, for example.. in the plugin it enqueues a file
wp_enqueue_style("myrp-stuff", MYRP_PLUGIN_URL . "/myrp-hotlink-css.php");
so I've tried:
wp_dequeue_style('myrp-stuff');
wp_deregister_style('myrp-stuff');
It doesn't work
However, when the page/post is rendered it shows as
<link rel='stylesheet' id='myrp-stuff-css' href='http://www.modernlogic.co/wp/wp-content/plugins/MyRP/myrp-hotlink-css.php?ver=3.4.2' type='text/css' media='all' />
It addes -css to the id and it refuses to dequeue/deregister and be moved.
I have also tried the following with no luck
wp_dequeue_style('myrp-stuff-css');
wp_deregister_style('myrp-stuff-css');
Any suggestions?
Scripts and styles can be enqueued in any order and at anytime before wp_print_* actions are triggered. Which can make it difficult to remove them from the queue before output.
To make dequeue work consistently hook into into wp_print_styles or wp_print_scripts with a high priority, as this will remove the scripts and styles just before output.
For instance in your plugin loader code or template's functions.php file you could have a function and action hook like this:
function remove_assets() {
wp_dequeue_style('myrp-stuff');
wp_deregister_style('myrp-stuff');
}
add_action( 'wp_print_styles', 'remove_assets', PHP_INT_MAX );
Setting a high priority (third argument to add_action) when hooking into the action will help ensure that the callback remove_assets gets called last, just before scripts/styles are printed.
Note, while this technique is legitimate for removing scripts/styles it should't be used for adding assets. See this Wordpress Core blog post for more info.
Just to be sure, have you placed your code inside a function called by an action like this?:
add_action('wp_enqueue_scripts', 'dequeue_function');
function dequeue_function() {
wp_dequeue_style( array('myrp-stuff', 'myrp-stuff-css') );
wp_deregister_style( array('myrp-stuff', 'myrp-stuff-css') );
}
