I have been trying to include Gridster into my WordPress Backend but it simply doesn’t work. The frontend works fine, but I can’t figure out why, because the files are actually in the following directories.
First way I tried it:
function add_my_scripts() {
wp_enqueue_script('jquery');
wp_enqueue_script( "gridster-script", plugins_url( '/js/jquery.gridster.min.js', __FILE__ ), array('jquery') );
wp_enqueue_script( "gridster-script-extra", plugins_url( '/js/jquery.gridster.with-extras.min.js', __FILE__ ), array('gridster-script'), true );
wp_enqueue_script( "gridster-script-custom", plugins_url( '/js/gridster.js', __FILE__ ), array('jquery'), '1.0', true );
}
Second one:
function add_my_scripts() {
wp_enqueue_script('jquery');
wp_enqueue_script('gridster-script', plugin_dir_url(__FILE__) . '/js/jquery.gridster.min.js', array('jquery') );
wp_enqueue_script('gridster-script-extra', plugin_dir_url(__FILE__) . '/js/jquery.gridster.with-extras.min.js', array('gridster-script') );
wp_enqueue_script('gridster-script-custom', plugin_dir_url(__FILE__) . '/js/gridster.js', array('jquery') );
}
Third and last one:
function add_my_scripts() {
wp_enqueue_script('jquery');
wp_enqueue_script( 'gridster-script', get_template_directory_uri() . '/js/jquery.gridster.min.js', array('jquery'), '1.0.0', true );
wp_enqueue_script( 'gridster-script-extra', get_template_directory_uri() . '/js/jquery.gridster.with-extras.min.js', array('gridster-script'), '1.0.0', true );
wp_enqueue_script( 'gridster-script-custom', get_template_directory_uri() . '/js/gridster.js', array('jquery'), '1.0.0', true );
}
You can’t randomly use plugin url functions, and need to choose the correct one for your use case. Assuming
__FILE__
is correctly referring to the main plugin file, you’ll need to hook that function into theadmin_enqueue_scripts
action hook:
