Function and usage of list_core_update() in wordpress


Answers ( 1 )


    The list_core_update() function in WordPress is a part of the WordPress core and is used to list available updates for the WordPress core software. Here's a detailed explanation of its functionality and usage:

    Function: list_core_update()


    • Lists Available Core Updates: This function is used to display available updates for the WordPress core. It's typically used in the WordPress admin dashboard to inform administrators of new versions or maintenance releases.


    • $update (object, required): This is the only parameter for the function. It is an object representing the update that is available. This object typically contains details about the update, such as the version number, the package URL, and other relevant information.


    In a typical WordPress installation, this function is not directly invoked by theme or plugin developers. It's primarily used by the WordPress system itself, especially in the admin area to show updates. However, if there is a need to programmatically display or manage WordPress core updates within a custom plugin or theme, this function can be utilized.

    Sample Usage

    // Assume $update is an object containing update information
    $update = (object) [
        'current' => '5.9', // Current WordPress version
        'version' => '6.0', // New version available
        'locale' => 'en_US',
        // ... other properties
    // List the core update using the function

    In this example, $update is an object that you might have obtained from WordPress core functions or API, indicating that an update from version 5.9 to 6.0 is available. The list_core_update() function then uses this object to display the update information.


    • It's important to note that handling core updates is a sensitive operation and should generally be left to the WordPress system itself or handled by experienced developers.
    • The usage of this function outside of the WordPress admin context is rare and should be done with a thorough understanding of the WordPress update mechanics.
    • Always ensure that your WordPress site is backed up before performing any updates, whether manually or through custom code.
