I have a basic bunch of CSS/Js files defined in my functions.php file. There I register and enqueue those scripts and stylesheets.
But in specific situations I want to load additional scripts based on the site template which is used.
I tried to register and enqueue those additional scripts in the specific template file, but it didnt work. It does only work when included in the functions.php.
What is the correct way to do this?
You can try like this
add_action( 'wp_enqueue_scripts', 'enqueue_file' );
function enqueue_file() {
if(is_front() || is_archive()){ // you can set here condition
wp_enqueue_style( 'main-css', get_template_directory_uri() .
'/static/css/main.min.css"' );
}
}
add this to your functions.php in child theme:
add_action(
'wp_enqueue_scripts',
'loadActionFrontend'
);
function loadActionFrontend()
{
if( is_page( 'pageid here' ) ) {
wp_register_script(
'scriptName',
'scripturl',
[],
'',
true
);
wp_enqueue_script('scriptName');
}
}
with the query if( is_page( 'pageid here' ) ) you can insert your desired pageid where the script shold loaded.

Trying to learn plugins creation in Wordpress, i want to register/enqueue some scripts.
if i do this the proper way :
function my_script_enqueuer() {
wp_register_script( "my-script", plugins_url("plugin/js/my-script.js"), array('jquery'), 0.2, true );
wp_enqueue_script( 'my-script' );
}
add_action( 'wp_enqueue_scripts', 'my_script_enqueuer' );
It does not work at all.
If i remove the function :
wp_register_script( "my-script", plugins_url("plugin/js/my-script.js"), array('jquery'), 0.2, true );
wp_enqueue_script( 'my-script' );
It works fine.
Why ?
How can i make the proper way working ?
Some infos
Plugin is of course activated in Wordpress
wp_head() and wp_footer() are at their respective places
Function is in an include php file.
You might try the following. Notice I consolidated the enqueue and the register functions. The enqueue function will register the script for you, so you don't need both. That would be an unlikely reason for this not working, but you really only need to use register function if you're doing so globally and enqueuing in different functions.
function my_script_enqueuer() {
wp_enqueue_script( 'my-script', plugins_url('js/my-script.js', __FILE__), array('jquery'), 0.2, true );
}
add_action( 'wp_enqueue_scripts', 'my_script_enqueuer' );
I added custom javascript to a wordpress theme through the wp_enqueue_script()
function.
I placed my file in theme-folder/js/my-javascript.js
But it would not be found by wordpress! I would see the script tag in the html source inserted by wordpress, but clicking on it would take me to a "not found page". I looked around everywhere to see if this was some caching issue. Turned off caching, still nothing.
Finally, I ended up placing my-javascript.js file in the root of theme-folder, instead of 'js' folder. And now my js file was being found and loading.
But now a new problem I don't understand.. I would edit my file and the changes wouldn't reflect! I would have to change the file name of my js file everytime I made a change, renaming the file in my enqueue script function as well...I just wanted to get this task done.
So why does this happen? The site is hosted on dreamhost, and I suspect they used a one-click installer. Does dreamhost do some sort of caching on its own? and that's why?
Am I dumb? or does wordpress somehow know that I hate it?
Edit:
This is how I'm loading the script and how I left it working, but why won't my script refresh when I make changes and why doesn't it work when I place it in theme's 'js' folder?
/* Add floater script */
function add_floater_div_script(){
/* wp_enqueue_script( 'script', get_template_directory_uri() . '/js/script.js', array ( 'jquery' ), 1.1, true); */
if ( is_page(1208) ) {
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js', array('jquery'), '', true);
}
}
add_action( 'wp_enqueue_scripts', 'add_floater_div_script' );
Edit: Changed code from "array ( " to "array(" because someone thought this was a problem. I did a quick check myself and PHP is ok with this space so this does not explain the weird wordpress behaviour I'm trying to solve.
Yeah, caching gets really annoying, Though hard reloading should solve the prob but we can't expect client to do it everytime. And WordPress has added a way to take care of that :)
wp_enqueue_script accepts 4th parameter as version number...
https://developer.wordpress.org/reference/functions/wp_enqueue_script/
So just update version after each update...
For development, Just set it as time()... So that it is reloaded every single time and never cached...
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js', array('jquery'), time(), true);
Your code will look something like this...
/* Add floater script */
function add_floater_div_script(){
/* wp_enqueue_script( 'script', get_template_directory_uri() . '/js/script.js', array ( 'jquery' ), 1.1, true); */
if ( is_page(1208) ) {
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js', array('jquery'), time(), true);
}
}
add_action( 'wp_enqueue_scripts', 'add_floater_div_script' );
BE SURE TO REMOVE time() FROM PRODUCTION VERSION.
Or your file will never be cached by browser... Just set the version of your theme after dev is complete, so that every new version gets JS updated.
Try by wrapping your enqueue action in a function that you'll call on after_setup_theme hook in your functions.php
<?php
add_action( 'after_setup_theme', 'yourtheme_theme_setup' );
if ( ! function_exists( 'yourtheme_theme_setup' ) ) {
function yourtheme_theme_setup() {
add_action( 'wp_enqueue_scripts', 'yourtheme_scripts' );
}
}
if ( ! function_exists( 'yourtheme_scripts' ) ) {
function yourtheme_scripts() {
if ( is_page( 1208 ) ) {
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js', array( 'jquery' ), '', true );
}
}
}
Also be sure you're on page with id of 1208 to see if the script is actually loaded (because of the conditional).
And do a hard refresh (Ctrl+Shift+R).
The most common issue I see is an error in how you're enqueueing the file. Can you post code in your functions.php file that's enqueuing the JS file? Always be sure to reference the codex and other developer materials as well: https://developer.wordpress.org/themes/basics/including-css-javascript/
For future reference, it should look something like this:
wp_enqueue_script( 'script', get_template_directory_uri() . '/js/my-javascript.js');
Edit: After OP posted their code I saw they have a space after array which is causing an error, here is the correct code:
function add_floater_div_script() {
if ( is_page( 1208 ) ) {
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js', array( 'jquery' ), '1.0.0', true );
}
}
add_action( 'wp_enqueue_scripts', 'add_floater_div_script' );
add_action('wp_enqueue_scripts', 'load_scripts', 12);
function load_scripts() {
wp_enqueue_script('filename', get_template_directory_uri() . '/js/filename.js', array(), '1.0.0', true );
}
This is the proper way to import js in wordpress..
An really easy way to prevent caching of loaded resource files like Javascript-files is to add an random value after the filename that is to be included like so:
wp_enqueue_script( 'custom-floater', get_template_directory_uri() . '/custom-floater-8.js' . '?' . rand(), array('jquery'), '', true);
The PHP function
rand()
generates a random number and is appended to the file name after a '?' as query string. This forces reloading of the file every time the webpage is loaded.
Of course dismiss it for the production version.
Sometimes the issue could be simple somewhere a duplicated declaration of the name of the enqueue_script.
wp_enqueue_script( 'custom-script', get_template_directory_uri() . '/custom-floater-
8.js', array('jquery'), '', true);
...
wp_enqueue_script( 'custom-script', get_template_directory_uri() . '/custom-floater-
8.js', array('jquery'), '', true);
Don't use twice the same name 'custom-script' for example. The second will not be loaded.
I am trying to dequeue the following plugin scripts:
function afg_enqueue_cbox_scripts() {
wp_enqueue_script('jquery');
wp_enqueue_script('afg_colorbox_script', BASE_URL . "/colorbox/jquery.colorbox-min.js" , array('jquery'));
wp_enqueue_script('afg_colorbox_js', BASE_URL . "/colorbox/mycolorbox.js" , array('jquery'));
}
I tried adding this in functions.php:
add_filter('wp_print_styles', 'remove_mycred', 100);
function remove_mycred() {
wp_dequeue_script( 'afg_colorbox_script' );
wp_dequeue_script( 'afg_colorbox_js' );
}
But it does not work at all - both scripts are still there.
There are other scripts that I have no problems dequeuing - just not those.
I suspect jquery has something to do with my problems?
thanks!

You have two problems here, you should use wp_enqueue_scripts hook to hook your function to. Secondly, you will need to go and look at the priority which the author used to enqueue these scripts, and then give your action hook a lower (higher number) priority. Your code should look something like this
function remove_mycred() {
wp_deregister_script( 'afg_colorbox_script' );
wp_dequeue_script( 'afg_colorbox_script' );
wp_deregister_script( 'afg_colorbox_js' );
wp_dequeue_script( 'afg_colorbox_js' );
}
add_action( 'wp_enqueue_scripts', remove_mycred, 9999 );
how do I actually add jQuery to html5blank wordpress theme by toddmotto?
I'm quite new to wordpress so I'm not really sure how does this work.
For normal html, I'll just link a script tag of jquery and another script tag with $(document).ready.. . . . . and start the jquery codes.
Would really love if someone who had experience using html5blank theme could shed some light.
Thanks much!
The WordPress recommends add jquery from WordPress itself.So you can add jquery using following way.
Add code to your current theme functions.php file.
function func_add_my_jquery() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'func_add_my_jquery' );
I load all my scripts from functions.php by using wp_enqeue_script. This will avoid duplicate loading.
If you only want to load Query, you can do this by:
function load_my_scripts() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'load_my_scripts' );
This will load the jQuery that follows WP. You can see other default scripts you can load here:
If you want to load other JS scripts, then you must use this:
function theme_name_scripts() {
wp_register_script( 'my-script', get_stylesheet_directory_uri() . '/js/my-script.js', array('jquery') );
wp_enqueue_script( 'my-script' );
}
add_action( 'wp_enqueue_scripts', 'theme_name_scripts' );
The array('jquery') is for dependencies and in this case means that jQuery must be loaded before this script can be loaded.
If you want to register a newer version of jQuery, you first have to deregister the loaded jQuery:
wp_deregister_script( 'jquery' );
