Title: jQuery script in plugin doesnt work – "$ is not a function" Last modified: August 21, 2016 --- # jQuery script in plugin doesnt work – "$ is not a function" * [Reuven Karasik](https://wordpress.org/support/users/kinging/) * (@kinging) * [12 years, 11 months ago](https://wordpress.org/support/topic/jquery-script-in-plugin-doesnt-work-is-not-a-function-1/) * hi, I developed plugin with a lightbox script(using colorbox). there are two parts of code, one on the header to import the jQuery directory, the .js file and the .css file, and also a simple jQuery script. * the other part sould be somewhere in the tag, so i put it on the footer. here is the codes i have used: * ``` function head_code(){ echo ""; wp_enqueue_script( 'lbscript', 'http://reuven.karasik.org/plugins/files/lightbox/jquery.colorbox.js' ); wp_enqueue_script( 'lbjquerysciprt', 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js' ); $code = ""; echo $code; }; add_action('wp_head', 'head_code'); ``` * and for the other part: * ``` function foot_code() { echo ""; } add_action('wp_footer', 'foot_code'); ``` * if the way i put those codes is wrong, please tell me and give me example of right using. * anyway, the jQuery scripts arnt working, not when i write $(…) and not when i write jQuery(…). the error says that there is no function “$”, witch means that the compiler thinks that i didnt import the jQuery directory, witch i did. beside that, there are other j|Query script from my theme, that work perfectly, and when i put the same code in a html file without wordpress it works. do you have any idea why the import of the jquery directory isnt working?
