I have been trying to use wp_enqueue_script() to load a JS script into one of my pages but it keeps throwing a "Failed to load resource" 404 error in the console (running Chrome). My code is as follows:

myplugin.php:

function myplugin_load_script() {
    wp_enqueue_script( 'myplugin-testjs', (plugin_dir_path( __FILE__ ) . "scripts/myplugin-test.js"), array('jquery'), null, true );

    add_action('wp_enqueue_scripts', 'myplugin_load_script');

}

myplugin-test.js:

alert("Hello!");

I have checked the HTML tag and the development tools and both of them display the correct URL (eg. wp-content/plugins/myplugin/scripts/myplugin-test.js).

I have also checked that the file does exist there and the name is correct, PHP throws no errors either. Thanks for any help!

Reset to default 2

Your syntax is wrong. The action must be defined outside of the callback.

Also, you are using plugin_dir_path() function, which gets the path to plugin directoy in the filesystem of the server, not the url. You should use plugin_dir_url() instead.

add_action( 'wp_enqueue_scripts', 'myplugin_load_script' );
function myplugin_load_script() {
    wp_enqueue_script( 'myplugin-testjs', plugin_dir_url( __FILE__ ) . "scripts/myplugin-test.js", array('jquery'), null, true );

}
