This comment is automatically added by Cake if the debug value in app/config/core.php is greater than 0.

As long as you only work with HTML in your views, this is no problem. But if you have to use a different format like JSON, you won’t love this comment and you have to get rid of it ;-)

There are two ways to accomplish this.

The first approach is to set the debug value to 0, for example in a single action, with:

Configure::write('debug', 0);

The other approach is to remove the code snippet which adds the comment with the page execution time. For this purpose open app/webroot/index.php, and at the end of the file remove the following code:

if (Configure::read() > 0) {
    echo "<!-- " . round(getMicrotime() - $TIME_START, 4) . "s -->";
}

Happy baking!

This header is shown because you don’t have defined your own layout yet, and so the default layout is used which comes with CakePHP (located in /cake/libs/view/layouts/default.ctp /cake/libs/view/templates/layouts/default.ctp (respectively .thtml with CakePHP 1.1)). Now the first idea is to edit this file. That would work. But it violates the golden rule of CakePHP: Don’t edit files in the cake folder! So, instead you have to copy the file to /app/views/layouts. Then you can edit the layout in any way you want.

Happy baking :)

Update 2009-05-29: Fixed path to layout because it has changed since this article has been written. Thanks to Göran K. for the hint!

One point is that CakePHP is a volunteer project, so it is almost impossible to predict what amount of work can be done during a certain time period, and hence it becomes difficult to say when it will be done. There are times with high activity (i.e. a lot of commits), but there are also times with almost no activity, see the time line of trac to see that “pattern”.

Setting a release date also leads to expectations. People expect that you deliver on that date. If you cannot deliver, people start complaining. And if that happens too often, the project gets the image of being unreliable.

So we have to wait until it’s done :)

function action() {
    Configure::write('debug', '2');

    // do something
}

Please notice that the key must be in lowercase, ‘DEBUG’ won’t have the desired effect.

PS: I shut down the j.42dh.com password manager service as nobody used it ;-) A slightly modified version of the application can be downloaded from http://apps.42dh.com/jumpjump.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at
/home/dho/projects/test/trunk/app/controllers/users_controller.php:7) in /home/dho/projects/cake_1.2.x.x/cake/libs/session.php
on line 131

It is a bit nasty. The warning points us to line 7 (the last line). Hm, but line 7 looks correct, doesn’t it?

<?php
    class UsersController extends AppController {
        var $uses = null;

        function edit() {}
    }
?> 

Well, if you mark line 7 with your mouse, you see that there is a space after the “>” character. And this space is the cause of the warning. If you remove the space, the warning disappears.

class ModelWithoutTable extends AppModel
{
    var $useTable = false;
}

// app/controllers/users_controller.php
class UsersController extends AppController
{
    function beforeFilter()
    {
        if ($this->action != 'login')
        {
            // execute beforeFilter logic
        }
    }

    function login()
    {
        // do login
    }

    function edit($id)
    {
        // do edit
    }

    function delete($id)
    {
        // do delete
    }
}

// tested with CakePHP r1892
class MyController extends AppController
{
    // var $uses = null; works too
    var $uses = array();

    function index()
    {
    }
}

If you omit the “var $uses = array();” you will get a “missing model” error.
