Function and usage of media_upload_flash_bypass() in wordpress


Answers ( 1 )


    The media_upload_flash_bypass() function in WordPress is quite straightforward in its purpose. It's designed to display a message related to the multi-file uploader, particularly in scenarios where the Flash-based uploader is not being used or is bypassed. This function becomes relevant because WordPress historically used a Flash-based media uploader, which has been largely replaced due to the obsolescence of Flash.

    Function Overview

    • Function Name: media_upload_flash_bypass()
    • Purpose: To display a message or notification in the WordPress admin area, particularly in the media upload section, indicating that the traditional Flash-based uploader is not in use.
    • Use Case: Primarily used when the Flash-based media uploader is either disabled or unsupported, prompting the user to use an alternative multi-file uploader method.

    Sample Usage

    The usage of media_upload_flash_bypass() is typically handled within the WordPress core, specifically in the media upload sections of the admin area. Here's a hypothetical example to illustrate how it might be used in a plugin or theme:

    function custom_media_uploader() {
        // Check if Flash-based uploader is disabled or unsupported
        if ( condition_to_bypass_flash_uploader ) {
            // Use media_upload_flash_bypass() to display the relevant message
        } else {
            // Code to implement the Flash-based uploader (if still relevant)
            // ...
    // Hook this function to an appropriate action in WordPress
    add_action( 'some_relevant_action_hook', 'custom_media_uploader' );

    In this sample code:

    • The function custom_media_uploader() is defined to handle the media upload process.
    • It checks a condition (condition_to_bypass_flash_uploader) to determine if the Flash-based uploader should be bypassed.
    • If the condition is true, media_upload_flash_bypass() is called to display a message indicating that an alternative uploader should be used.
    • If Flash is still relevant, the else block would contain code for implementing the Flash-based uploader.

    Important Notes

    • Context: This function is relevant in the context of WordPress's admin interface and is typically not used on the front-end of a site.
    • Flash Obsolescence: With the obsolescence of Flash, the relevance of this function has diminished, and modern WordPress versions might handle media uploads differently.
    • WordPress Updates: Always ensure compatibility with the latest WordPress version, as functions and their usage can change over time.

    Keep in mind that WordPress continuously evolves, and the usage of such functions might change or become deprecated in future versions. Always refer to the latest WordPress documentation for the most accurate and up-to-date information.
