Based on your code, I think the problem may have been that you were checking a variable that was undefined. You were checking $db_email, which in your function was an undefined value, so you’d be looking for an empty result. You need to check the value passed to email_exists() (which would be the email being … Read more
You can use get_page_by_title http://codex.wordpress.org/Function_Reference/get_page_by_title to check if another page/post is using the same title. If so, get the content of that post and insert it using wp_insert_comment, and delete the original post with wp_delete_post. Finally, glue all these together inside the save_posts action hook.
WordPress has a whole set of useful functions to handle. It’s called wp_send_json(). You have success and error functions too. ob_start(), ob_get_clean() would be useful in case you want to include some views (~ MVC) in your shortcode, e.g in your shortcode handler. I don’t see here why you would use them to pass data … Read more
You should not declare functions in your templates. The templates are for outputting content. The function_exists() will check if the function is declared before the function_exists() call, not after it, and templates are loaded after functions.php file, since you can control them by using the template_redirect filter. Declare your function in your theme’s functions.php file, … Read more

The divisors loop assumes that the next row is 1000 times larger than the current one so I think you’ll have to change the logic here, e.g. keep iterating until the divisor is too big and use the previous one e.g. if (!isset($divisors)) { $divisors = array( pow(10, 0) => ”, pow(10, 3) => ‘K’, … Read more
Instead of redefining wp_star_rating() for the front end, you should be able to just use the built-in function. From the Codex page for wp_star_rating(): In order to use this function on the front end, your template must include the wp-admin/includes/template.php file and enqueue the appropriate dashicons CSS font information. (emphasis mine) A code sample is … Read more
Use if( file_exists(plugin_dir_path(__FILE__) . ‘myfile.ext’) ) {} instead of if( file_exists( plugins_url( “myfile.ext”, __FILE__ ) ) ) {} See plugin_dir_path in the Codex.
You can remove_action and add_action with your own action. (https://codex.wordpress.org/Function_Reference/remove_action) In your child theme functions.php you can add this code for example : add_action(‘init’, ‘remove_talon_footer’); // Remove your parent theme actions function remove_talon_footer() { remove_action(‘talon_footer’, ‘talon_footer_sidebar’, 7); // Use same priority remove_action(‘talon_footer’, ‘talon_footer_credits’, 8); remove_action(‘talon_footer’, ‘talon_footer_menu’, 9); } /** * Footer sidebar */ function my_talon_footer_menu() … Read more
You should wrap your function in parent theme like this, not in child theme function.php if (!function_exists(‘TaskerDev_get_first_post_image_fnc’) ){ function TaskerDev_get_first_post_image_fnc($pid, $w = 100, $h = 100) { //Parent theme code here } }
