I can get this to work in the header but how can I get it in the footer. I use thesis framework on my wordpress.
function load_scripts() {
wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'http://code.jquery.com/jquery-1.7.2.min.js');
wp_enqueue_script( 'jquery');
wp_register_script( 'bootstrap', '/wp-content/themes/thesis/custom/js/bootstrap.min.js', true);
wp_enqueue_script( 'bootstrap');
}
add_action('wp_enqueue_scripts', 'load_scripts');
I put true and it doesn't seem to work. I've been using this as a reference.
wp_enqueue_script( $handle,$src ,$deps ,$ver ,$in_footer );
It looks like you're passing true in the wrong place - WordPress will interpret that as the value for $deps. While $deps is optional, you need to provide it if you want to specify a subsequent parameter. The codex entry for wp_register_script tells you the default values - just pass those.
So your wp_register_script call should be:
wp_register_script( 'bootstrap', '/wp-content/themes/thesis/custom/js/bootstrap.min.js', array(), false, true);
Probably worth using get_bloginfo to get your template directory, rather than hardcoding it too.

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 want to use Bootstrap framework for my Wordpress.. how to edit in the functions.php ? i find somewhere tell the code like this
function enqueue_my_scripts() {
wp_enqueue_script( 'jquery', '//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js', array('jquery'), '1.9.1', true); // we need the jquery library for bootsrap js to function
wp_enqueue_script( 'bootstrap-js', '//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js', array('jquery'), true); // all the bootstrap javascript goodness
}
add_action('wp_enqueue_scripts', 'enqueue_my_scripts');
and what is that mean of first paragraph function enqueue_my_scripts() and add_action('wp_enqueue_scripts', 'enqueue_my_scripts'); in the last paragraph ?
Those are called "hooks" and you can read about them here: http://codex.wordpress.org/Plugin_API
Otherwise your code is essentially correct, with one mistake. You have jQuery as a dependency to jQuery, which means it is never loaded and subsequently bootstrap is never loaded:
wp_enqueue_script(
'jquery',
'//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js',
array( 'jquery' ), // <-- Problem
'1.9.1',
true
);
Solution:
wp_enqueue_script(
'jquery',
'//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js',
array(), // <-- There we go
'1.9.1',
true
);
But, there's one more thing. WordPress already has jQuery ready for you to enqueue (i.e. wp_enqueue_script( 'jquery' ); will load the local copy of jQuery). It isn't necessary but I think it is best practice to enqueue a CDN version of a script with a suffix, i.e.:
wp_enqueue_script(
'jquery-cdn',
'//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js',
array(),
'1.9.1',
true
);
// And then update your dependency on your bootstrap script
// to use the CDN jQuery:
wp_enqueue_script(
'bootstrap-js',
'//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js',
array( 'jquery-cdn' ),
true
);
It is correct to enqueue external scripts with that function?
It works but doesn't it slow down opening the site?
wp_register_script( 'google-maps', 'http://maps.googleapis.com/maps/api/js?sensor=true', null, null, true );
wp_register_script( 'jsapi', 'https://www.google.com/jsapi', null, null, true );
wp_register_script( 'bootstrap', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js', null, null, true );
wp_register_script( 'unveil', get_template_directory_uri() . '/new-js/jquery.unveil.min.js', null, null, true );
No, it doesn't slow the site (at least not enough to make it a reason for not using it). This is the correct way to enqueue any type of script in WordPress. All this function does is add the proper <link> tags (with dependencies) to your HTML <head>.
However, for some reason, you haven't included dependencies in your code. For example, Bootstrap requires jQuery, so you should include it in your function:
wp_enqueue_script( 'bootstrap', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js', array('jquery'), '3.3.5', true );
As shown above, you should also consider using wp_enqueue_script() instead of wp_register_script(), since it will save you a step.
I am working on my first plugin and it is coming along alright. However, I am not able to load my scripts (CSS and JS) from my plugin. This is my code:
function my_scripts() {
wp_enqueue_style('my-style', plugins_url( 'my-plugin/my-style.css') );
wp_enqueue_script( 'my-js', plugins_url( 'my-plugin/my-js.js' ), array('jquery'), '', true );
} add_action( 'wp_enqueue_scripts', 'my_scripts' );
I must be missing something... such a simple code to not be working :(
Your code looks pretty much correct, but check out Plugins URL Page and see this particular part:
If you are using the plugins_url() function in a file that is nested inside a subdirectory of your plugin directory, you should use PHP's dirname() function
Basically, you need to load like this:
plugins_url( 'my-plugin/my-js.js' , __FILE__ ),
Well, I got it. My mistake was that I was using the wrong hook! Duh! In the admin side, you use the hook admin_enqueue_scripts and in the front side you use wp_enqueue_scripts to hook your function to enqueue your scripts to WordPress.
Here is a simple example to import from your plugin. If you want to enqueue scripts from your theme, you should use get_template_directory_uri() function to get the proper path.
From your custom plugin to the admin side:
function load_my_scripts() {
wp_enqueue_style('my-style', plugins_url( 'my-style.css', __FILE__ ));
wp_enqueue_script( 'my-js', plugins_url( 'my-js.js', __FILE__ ), array('jquery'), '', true );
} add_action( 'admin_enqueue_scripts', 'guide_express_scripts' );
From your custom plugin to the front side:
function load_my_scripts() {
wp_enqueue_style('my-style', plugins_url( 'my-style.css', __FILE__ ));
wp_enqueue_script( 'my-js', plugins_url( 'my-js.js', __FILE__ ), array('jquery'), '', true );
} add_action( 'wp_enqueue_scripts', 'guide_express_scripts' );
