I am uploading files from the frontend. It works perfectly, yet I am getting the error:

Constant ABSPATH already defined

This is at the top of my file upload script:

require ($_SERVER['DOCUMENT_ROOT'] . "/wp-load.php");




// require two files that are included in the wp-admin but not on the front end.  These give you access to some special functions below.




require ($_SERVER['DOCUMENT_ROOT'] . "/wp-admin/includes/file.php");




require ($_SERVER['DOCUMENT_ROOT'] . "/wp-admin/includes/image.php");

wp-load.php is not being loaded anywhere else manually, only here. The file upload works as expected, the only issue is the Notice that PHP is spitting out.

If I use require_once then I get more errors (though it does still upload as expected?).

Any ideas?

Edit: more information

A search through /wp-content/* shows the term wp-load only once - that is from the above code.

Maybe there is a way to autoload wp-load.php without including the phrase wp-load??

The code requiring wp-load is within a theme template (not a plugin). Specifically, within a page-template that allows a custom post to be added/edited from the frontend.

If I remove the line that requires wp-load.php, then the image upload still works. However, I get the following errors (sensitive info in directory structure has been omitted):

This error is referencing the $file_array array from here:

if ($count_files > 0) {




    foreach ( range( 0, $count_files ) as $i ) {









        // create an array of the $_FILES for each file
