How to get the root directory of CakePHP?

Question

I've got a view with a formular (which isn't created with the form helper). For example, I have CakePHP installed in a folder called 'myfolder1'.

So my formular starts with that line:

<form id="ctrlAddForm" method="post" action="/myfolder1/ctrl/add" accept-charset="utf-8">

But if I rename the root folder, I have to edit all formulars (2 yet). Is there any constant or function which represents the root directory / name?

I've read about the constant ROOT. Should I use that variable?

Solution

1. You can define a constant ROOT_NAME in app\webroot\index.php with basename(ROOT).

2. You can use the HTML Helper function url(). For example in the action attribute of the form tag:

   $this->Html->url(array('controller' => 'ctrl', 'action' => 'add'));

Answer 1

Well, you could try this normal ol' PHP function: basename

basename(APP);

Since that doesn't work I actually opened up my own Cake install. Try this:

basename(dirname(APP));

Answer 2

I had to get the URL of the CakePHP document root to use in Javascript, and I was able to set it up using the solution above:

<script language="Javascript">
$(document).ready(function() {
         docRoot = '<?php echo $this->Html->url('/'); ?>';
}
</script>

and that piece of code - $this->Html->url('/') - works perfectly in getting the root directory/URL for CakePHP.

Answer 3

This page has a list of the constants that can be used, http://book.cakephp.org/view/1141/Core-Definition-Constants

Answer 4

YOu can check the routes /var/www/yourprojectname/cake/conf/paths.php

you can get all constant variable are being used through the CAKEPHP.

I hope that helps.
