Easy way to check if jQuery is already enqueued
Had a plugin wreaking some havoc today because it was overloading jquery.js with a minified, older version. Plugin authors: There’s a really simple way to check if jQuery or a jQuery library is already registered and enqueued. This covers really obscure edge cases where a plugin may have de-registered WordPress’s default scripts.
The offending code:
wp_register_script('myjquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js', true, '1.6.4', false);
wp_enqueue_script('myjquery');
The fix:
// If jQuery isn't already enqueued, register and enqueue it
if ( ! jQuery ) {
wp_register_script('myjquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js', true, '1.7.2', false);
wp_enqueue_script('myjquery');
}
