Validation not working, not finding plugin library code

    My server side validation xxx.php cannot find “wpmsrc_check” after I embedded the validation php code.
    This always fails: function_exists( ‘wpmsrc_check’ )

    I created a custom form and my form statement is coded like this:
    action=”/wp-content/custom-php/xxx.php”

    I don’t understand why my xxx.php cannot find wpmsrc_check?
    It appears my xxx.php cannot access any plugin libraries, but how can I make it do so?

    Thanks for any help.

    Hi Alex,

    xxx.php cannot find wpmsrc_check because loading xxx.php directly bypasses WordPress.

    This is one reason you may see

    /** If this file is called directly, abort. */
if ( ! defined( 'ABSPATH' ) ) {
	die;
}

    in a core, plugin or theme file.

    To prove it, add that snippet to the top of xxx.php and see what happens.

    The technique required to handle this is called Post-Redirect-Get (PRG).

    1. Your form posts to the action file which processes the $_POST.
    2. The action file redirects to a target page, probably your form again.
    3. If necessary, the target page fetches the result of the $_POST (a new record, setting, etc.) and display feedback to the user (success, failure).

    I recently ran across this on the admin side. This StackOverflow answer helped me; you will need to determine the front-end equivalent.

    In case you’re using /custom-php as a directory for miscellaneous scripts, consider building a simple plugin instead of dropping files in /wp-content directly.

    Let me know if I can help with any of this.

    Chris

    Edit: After re-reading that SO thread, it seems the WordPress handler it refers to also works on the front-end. I have not tried that yet.
