function_exists() isn’t going to help you here. That needs to be in the parent theme for you to be able to do anything. The only way you’re going to be able to change this from your chid theme is to use remove_filter() to remove it from the parent theme, and then copy it into your … Read more
Since you are using a Child Theme, the functions.php file in there is loaded before the parent theme’s functions. So, if you define some_function() in the Child Theme, any declaration of that function in the parent theme will fail. If the parent theme is using a function_exists() to check if some_function() is defined, it should … Read more
The short answer to your question is yes; however, the methods to do this are a little bit hacky and generally I would recommend against all of them unless absolutely necessary. Since pluggable functions actually replace the stock function by way of function_exists() whichever plugin that “plugs” the function first will win. What you want … Read more
You can only declare a function once. My reccomendation is that you put the functions in the plugin, then use filters to override in the theme, e.g. In the plugins: function my_awesome_function() { return apply_filters( ‘my_awesome_function’, “plugin” ); } In your theme: add_filter( ‘my_awesome_function’, function( $value ) { return “theme”; } ); Now every call … Read more
Why exactly are you trying to redeclare that function? You can either edit the original function, or, better yet, use remove_action to remove add_action( ‘widgets_init’, ‘twentyeleven_widgets_init’ ); and then reattach your own function add_action(‘widgets_init’, ‘your_widgets_init_function’ );

The result of function_exists do not only depend on the file in which the function is declared and the file in which the call … Read more
You typed “mobiles” when you said you wanted to check for post type “mobile”. So simply remove the s ;). <? if( post_type_exists( ‘mobiles’ ) ) { echo ‘The Products post type exists’;} ?> Should be: <? if( post_type_exists( ‘mobile’ ) ) { echo ‘The Mobile post type exists’;} ?> If it’s still not working, … Read more
Php string not working in WordPress Functions.php (trying to fetch 1st category for each blog that post appears in the sidebar)
I don’t know if one is faster or slower than the other, but I would suggest that using apply_filters() is the better approach, because it is cleaner, and more intuitive (in the sense of doing things the “WordPress way”). EDIT If you’re doing comparison tests, shouldn’t you compare the time required to execute the following: … Read more
If you take a look at registrations in source there is no alias to load all of jQuery UI in bulk available and WP core itself uses pieces as dependencies individually. You could create and use such alias yourself (registered script handle with no URL and all of needed scripts as dependencies), but it might … Read more
