WordPress: Loading multiple scripts with enqueue

3 Views

I’m trying to load jQuery and other scripts into the header (or should it be footer), and I have the jQuery working sort of I can get an alert box running.

The thing is, jquery-2.0.3.min.js isn’t loading, and I don’t know if I’m doing the enqueue correctly. jquery-1.10.2 is loaded though. And also, the other script isn’t loading either. For both scripts (2.0.3 and other script), this is at the end: ?ver=3.6.1

Also I was reading that it might be better load both into one function?

So, any help would be appreciated! 

function load_jquery() {
    wp_register_script( 'jquery_script', get_template_directory_uri() . 'js/jquery-2.0.3.min.js', array( 'jquery' ) );
    wp_enqueue_script( 'jquery_script' );
}
add_action( 'init', 'load_jquery' ); // end jQuery

function another() {
    wp_register_script( 'another_script', get_template_directory_uri() . 'js/another.js', array( 'jquery' ) );
    wp_enqueue_script( 'another_script' );

}
add_action( 'init', 'another' );

  1. First thing jquery in there by default in wordpress so you dont have to register it , just enqueue it

    most of the jquery ui libs and core jquery files are already registered with wordpress so you only need to enqueue with right handle look here enqueue script

    wp_enqueue_script is used to enqueue script and wp_enqueue_style is used to enqueue style

    for calling custom js, its better to register script or style first before using

    wp_register_script // to register script

    wp_register_style // To register style

    then enqueue using wp_enqueue_script, wp_enqueue_style

    here is a sample code snippet for whole process from my site 

    function pr_scripts_styles() {

    wp_enqueue_script('jquery'); // just enqueue as its already registered 
    if ( is_singular() && comments_open() && get_option( 'thread_comments' ) )
        wp_enqueue_script( 'comment-reply' );

    /*   REGISTER ALL JS FOR SITE */
    wp_register_script('pr_cycle_all',get_stylesheet_directory_uri().'/js/pr-slider.js');
    wp_register_script('pr_slider',get_stylesheet_directory_uri().'/js/jquery.cycle.all.min.js');
    wp_register_script('pr_validation_engine',get_stylesheet_directory_uri().'/js/jquery.validationEngine-en.js');
    wp_register_script('pr_validation_locale',get_stylesheet_directory_uri().'/js/jquery.validationEngine.js');
    wp_register_script('stylethemes',get_stylesheet_directory_uri().'/js/stylethemes.js');
    wp_register_script('pr-jquery-ui',get_stylesheet_directory_uri().'/js/jquery-ui.js');
    wp_register_script('main-js',get_stylesheet_directory_uri().'/js/main.js');
    wp_register_script('pr-galleriffic',get_stylesheet_directory_uri().'/js/jquery.galleriffic.js');
    wp_register_script('pr-rollover',get_stylesheet_directory_uri().'/js/jquery.opacityrollover.js');
    wp_register_script('pr_colorbox',get_stylesheet_directory_uri().'/js/jquery.colorbox.js');
    wp_register_script('pr_jcarousel_js',get_stylesheet_directory_uri().'/js/jquery.jcarousel.min.js');


    //wp_register_script('google-map-api','https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false');



    /*   REGISTER ALL CSS FOR SITE */
    wp_register_style('pr_woocommerce',get_stylesheet_directory_uri().'/css/_woocommerce.css');

    wp_register_style('pr_sec_teal_grey',get_stylesheet_directory_uri().'/css/secondary-teal-grey.css');

    wp_register_style('pr_jcarousel_css',get_stylesheet_directory_uri().'/css/jcarouselskin.css');



    /*   CALL ALL CSS AND SCRIPTS FOR SITE */
    wp_enqueue_script('pr-jquery-ui');
    wp_enqueue_script('stylethemes');

    wp_enqueue_script('pr_cycle_all');

    wp_enqueue_script('pr_slider','','','',true);
    wp_enqueue_script('pr_validation_engine');
    wp_enqueue_script('pr_validation_locale');
    wp_enqueue_script('google-map-api');
    wp_enqueue_script('main-js');
    wp_enqueue_script('pr-galleriffic');
    wp_enqueue_script('pr-rollover');
    wp_enqueue_script('pr_colorbox');


    wp_enqueue_style( 'pr-style', get_stylesheet_uri(), array(), '2013-07-18' );
    wp_enqueue_style('pr_site_options');
    wp_enqueue_style('pr_woocommerce');
    wp_enqueue_style('pr_mobile');
    wp_enqueue_style('pr_sec_teal_grey');
    wp_enqueue_style('pr_teal_grey');
    wp_enqueue_style('validation_css');
    wp_enqueue_style('galleriffic_css');
    wp_enqueue_style('pr_colorbox_style');
    if(is_single()){
        wp_enqueue_script('pr_jcarousel_js');
        wp_enqueue_style('pr_jcarousel_css');
    }
}
add_action( 'wp_enqueue_scripts', 'pr_scripts_styles' );

    also remember to hook your function with wp_enqueue_scripts so that scripts & style load correctly add_action( 'wp_enqueue_scripts', 'pr_scripts_styles' );

  2. This works for me when using child theme, just be sure to use different names for the scripts:

    function my_scripts_method() {

    wp_enqueue_script(
        'script-name1',
        get_stylesheet_directory_uri() . '/some-script.js',
        array( 'jquery' )
    );
    wp_enqueue_script(
        'script-name2',
        get_stylesheet_directory_uri() . '/another-script.js',
        array( 'jquery' )
    );

}
add_action( 'wp_enqueue_scripts', 'my_scripts_method' );

  3. This is how i add styles and scripts works great for me.
    But i suggest before using it understand it first and then anyone can follow this approach there own way.

       function theme_files() {
        $styles = [
            ['handle' => 'style', 'src' => '../style.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'bootstrap', 'src' => 'bootstrap.min.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'font_awesome', 'src' => 'font-awesome.min.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'animate', 'src' => 'animate.min.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'lightbox', 'src' => 'lightbox.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'main', 'src' => 'main.css', 'deps' => false, 'media'=>"all"],
            ['handle' => 'responsive', 'src' => 'responsive.css', 'deps' => false, 'media'=>"all"]
        ];
        for ($i = 0; $i < sizeof($styles); $i++) {

            wp_enqueue_style($styles[$i]['handle'], get_template_directory_uri() . '/css/' . $styles[$i]['src'], $styles[$i]['deps'], $styles[$i]['media'] );

        }

        $scripts = [
            ['handle' => 'bootstrap', 'src'=>'bootstrap.min.js','dep'=> array( 'jquery' ),'var'=> false,'in_foot'=> true],
            ['handle' => 'lightbox', 'src'=>'lightbox.min.js','dep'=> array( 'jquery' ),'var'=> false,'in_foot'=> true],
            ['handle' => 'wow', 'src'=>'wow.min.js','dep'=> array( 'jquery' ),'var'=> false,'in_foot'=> true],
            ['handle' => 'main', 'src'=>'main.js', 'dep'=>array( 'jquery' ), 'var'=>false, 'in_foot'=>true]
        ];

        for ($i=0; $i < sizeof($scripts); $i++) {

            wp_enqueue_script( $scripts[$i]['handle'], get_template_directory_uri() . '/js/' . $scripts[$i]['src'], $scripts[$i]['dep'], $scripts[$i]['ver'], $scripts[$i]['in_foot'] );    

        }
    }
    add_action( 'wp_enqueue_scripts', 'theme_files' );
