The following code is in the same php script. But I get Uncaught ReferenceError: jQuery is not defined in chrome debugger.

validate.js is in plugins/validate/validate.js

I know this is the problem , as I tried validate.js when not using wordpress, by including it externally, & it worked fine. I am using the code below, on a page.

What is the solutions please?

add_action( 'init', 'load_jquery' );
function load_jquery() {
    wp_enqueue_style( 'jquery');

function add_my_css_and_my_js_files() {
    wp_register_script( 'validate', plugins_url( '/validate.js', __FILE__ ) );
add_action( 'wp_enqueue_scripts', "add_my_css_and_my_js_files" );

Just use deps parameter to include jQuery, change your code to:

    function add_my_css_and_my_js_files() {
        wp_register_script( 'validate', plugins_url( '/validate.js', __FILE__ ), array( 'jquery' ) );
    add_action( 'wp_enqueue_scripts', "add_my_css_and_my_js_files" );
  • Thanks. Now I get a `Uncaught ReferenceError: jQuery is not defined ' debug error – mattnewbie Feb 7 '14 at 17:08

    Remove the jquery loading portion of your code and then run wp_enqueue_script('validate'); right after the wp_register_script line in @1fixdotio's answer. – Andrew Bartel Feb 7 '14 at 17:16
