I’m developing a WordPress plugin and I’m running into an issue. I need to get info about the current user, but when I try to use wp_get_current_user(), I get an error saying the function is undefined.
After some digging, I found out that this might be because the file that has this function (/wp-includes/pluggable) doesn’t load until after plugins are loaded. This timing issue is causing the problem.
Does anyone know a workaround for this? How can I safely access user details in my plugin without running into this error? I’ve tried a few things, but nothing seems to work. Any help or suggestions would be really appreciated!
Here’s a simplified version of what I’m trying to do:
function my_plugin_function() {
$current_user = wp_get_current_user();
$user_name = $current_user->display_name;
// Do something with $user_name
}
add_action('init', 'my_plugin_function');
But this throws the undefined function error. What’s the best way to handle this?
I’ve encountered this issue in my WordPress development work as well. While the ‘plugins_loaded’ hook suggested earlier is a viable solution, another approach I’ve found effective is using the ‘wp_loaded’ action hook. This hook fires after WordPress, all plugins, and the theme are fully loaded, ensuring that all functions, including wp_get_current_user(), are available.
Here’s how you can modify your code:
function my_plugin_function() {
$current_user = wp_get_current_user();
$user_name = $current_user->display_name;
// Do something with $user_name
}
add_action('wp_loaded', 'my_plugin_function');
This method has consistently worked for me across various WordPress versions and plugin configurations. It’s a reliable way to ensure you have access to all WordPress functions without encountering timing issues.
I’ve dealt with this issue in my own plugins before. One trick that’s worked well for me is using the ‘init’ hook, but wrapping the function call in a check to see if the function exists. This way, you’re not relying on a specific load order. Here’s what I mean:
function my_plugin_function() {
if (function_exists('wp_get_current_user')) {
$current_user = wp_get_current_user();
$user_name = $current_user->display_name;
// Do something with $user_name
} else {
// Handle the case where the function isn't available yet
// Maybe log an error or set a flag to try again later
}
}
add_action('init', 'my_plugin_function');
This approach has been pretty solid for me. It gives you flexibility and helps avoid those pesky undefined function errors. Just remember to handle the case where the function isn’t available yet - you might want to set a flag and try again on a later hook if it’s critical to your plugin’s functionality.
hey there, i ran into this same issue before. try hooking into the ‘plugins_loaded’ action instead of ‘init’. that way you’re sure all the necessary WordPress functions are available. something like this:
