First of all, we must never directly insert custom codes into theme files. All your customization will be lost permanently on theme update (This is how WordPress work, all theme files will be overwritten). Also, we should always keep theme up to date to receive security and other updates. * There are many online tutorials which advise to insert custom codes at the end of theme’s functions.php file or some other file. It is a bad idea. * 2. For your specific problem (adding google reCAPTCHA) you may consider using some plugin [https://wordpress.org/plugins/search/reCAPTCHA/](https://wordpress.org/plugins/search/reCAPTCHA/) * 3. However, if you still want to use custom codes, either create a child theme( using plugin [Child Theme Configurator](https://wordpress.org/plugins/child-theme-configurator/)) OR simply use [code snippet](https://wordpress.org/plugins/code-snippets/) plugin( Code snippet plugin is like virtual functions.php file of the theme, which will not be overwritten). * 4. For your specific question above, You can use specific theme hook depends upon what code you are entering. If you want to add some custom JavaScript for reCaptcha verification you can use ‘wp_footer’ hook. * An example would be, * ``` function bayleaf_child_recaptcha_custom() { // Enter your custom code here. } add_action( 'wp_footer', 'bayleaf_child_recaptcha_custom' ); ``` * Please inform what specific code you want to enter, and I will inform the proper hook. * Note: Always backup your site before making PHP changes. * Thanks, * Thread Starter [TokoDaring.Com](https://wordpress.org/support/users/wpjakarta/) * (@wpjakarta) * [6 years ago](https://wordpress.org/support/topic/single-php-2/#post-12812612) * hello * yes, actualy i have code snippet to add every additional function code, but i think i have wrong on enqueue script hook, because if i write the code into my code snippet it causing error. * this is my code, need your advice to fixed this. * // code i inserted into main-loop.php `wp_enqueue_scripts('google-recaptcha',' https://www.google.com/recaptcha/api.js');` * //function.php * ``` // add google reCAPTCHA box before submit komentar function add_google_recaptcha($submit_field) { $submit_field['submit_field'] = '
