How to enable/disable debug messages for a certain action
An often asked question in the CakePHP IRC channel is: “How can I enable [or disable] the debug messages for a certain action?” The answer to this question is simple (works in both CakePHP 1.1 and 1.2):
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.
Nice snippet, i have never before used Configure class. So now i see the point of it …
no more editing core.php all the time; :)
Thanks.
Jesus, please don’t edit core all the time, write a simple
if($_GET['debug']) or a session base debug activator with
a cookie-extension for firefox. best way to activate debugging on live servers by the way.
nice snippet anyway :)
@Dejan, kojote: Thanks for your comments!
@kojote: You should not debug on live servers ;-)
Tell me if I m wrong, but you have to write
Configure::write(’debug’, ‘2′);
at the end of your action to see the sql queries
if you end up with
Configure::write(’debug’, ‘0′);
no query is displayed
@wluigi: Yes, that’s correct. The same values as used in app/config/core.php for the DEBUG constant.
does not quite work for me
I am trying to suppress debug output on some of the actions while leaving application-wide debug level at 2.
so i included the following line inside actions i so not want want to output debug info:
Configure::write(’debug’, ‘0′);
however i still get execution time and sql info appended at the end of the page.
I can see that the code does have some effect - “print_r” calls do not work which is behavior consistent with debug level 0
am i missing something?
i am running 1.1.12.4205
@zheka: Hm, I am not sure if it works with 1.1.12.x. I would try it with the latest stable release.
thanks
