PHP网址根目录和绝对路径

Question

I have been stuck on this for a day or two and can't see what the issue is. I have a file called webconfig.php with this code.

<?php
define('ABSOLUTE_PATH', '/home/es23/htdocs/CIT313/SP2016/a1');
define('URL_ROOT', 'http://corsair.cs.iupui.edu:20151/CIT313/SP2016/a1');
?>

In a form I want it to go to this page

<form action="<?php echo 'URL_ROOT' . '/add_products_to_inventory.php' ?>"method="post">

But when I press the button to proceed to that page I get a Not Found and it says--> The requested URL /CIT313/SP2016/a1/URL_ROOT/add_products_to_inventory.php was not found on this server.

I know the file is on the server but I'm pretty sure the URL_ROOT that is showing in between the a1 and add_products_to_inventory.php is incorrect. Can anyone steer me towards what would be causing this issue? Thanks in advance.

Yep, when you don't start with a protocol the link assume it's relative to the current path. Your link is not starting with a protocol because you used 'URL_ROOT' and when surrounding it in quotes like this it becomes a string, not a constant.

<form action="<?php echo 'URL_ROOT' . '/add_products_to_inventory.php' ?>"method="post">

should be

<form action="<?php echo URL_ROOT . '/add_products_to_inventory.php' ?>"method="post">
