I’ve been developing my own plugins for WordPress and, more reently, ClassicPress. At times it’s been necessary to check if a function exists.
It’s fairly straightforward to do this check:
if (!function_exists('azrcrv_get_breadrumbs')){
// code here
}
I also use a few plugins developed by other people. One of the ones I’ve been reviewing recently is Estimated Read Time by CodePotent.
John uses namespaces in his plugins which means the check also needs to include the namespace. You can check for this using the following syntax (the highlighted section is the namespace defined in the plugin):
if (function_exists('CodePotent\EstimatedReadTime\process_shortcode')){
// code here
}
I’m posting this as a reminder to myself as it took me a few minutes of searching before I found the right answer.
What should we write about next?
