Function and usage of doing_action() in wordpress


Answers ( 1 )


    The doing_action() function in WordPress is a useful tool for developers to check if a specific action hook is currently being processed. Here's a detailed explanation and sample usage:

    Function Definition

    • Function Name: doing_action()
    • Parameters: string|null $hook_name = null
    • Return Type: bool


    • Purpose: The doing_action() function is designed to determine whether a specific WordPress action hook is currently being executed. This is particularly useful in complex scenarios where hooks are nested or triggered within callbacks of other hooks.
    • Comparison with Other Functions:
      • current_action(): Returns the name of the most recent action being executed.
      • did_action(): Provides the number of times an action has been fired during the current request.
    • Behavior: If no parameter is given ($hook_name is null), doing_action() checks if any action is currently running. If a specific action name is provided, it checks if that particular action is in process.


    • $hook_name (string|null, optional): The name of the action hook to check. By default (null), it checks for any action currently being run.

    Return Value

    • Type: bool
    • Description: Returns true if the specified action is currently in the execution stack, and false otherwise.

    Sample Usage

    1. Check Any Action in Process:

      if ( doing_action() ) {
          // Code to execute if any action is currently being processed
    2. Check a Specific Action:

      if ( doing_action( 'init' ) ) {
          // Code to execute if the 'init' action is currently being processed

    Practical Scenarios

    • Debugging: Useful for debugging purposes, especially when trying to figure out the sequence of actions and their current state.
    • Conditional Logic: Implement conditional logic based on whether a specific action is currently being executed.


    • Stack Check: It's important to remember that doing_action() checks the entire stack of actions, not just the most recent one.
    • Nested Hooks: Very handy in scenarios with nested hooks or actions triggered within other action callbacks.


    doing_action() is a powerful function for WordPress developers, allowing for precise control and checks on the action hooks' execution status, thereby facilitating more complex and conditionally controlled functionalities within themes and plugins.
