Hi,
When I code in PHP, everything works fine until I use an IF statement. WHen I use one of them, the whole page comes out blank on my computer, and there is nothing wrong with the coding.
Show errors is on and everything, it happens when I use an IF statement.
Please help

Well something is obviously wrong with the code unless your if statement tells it to be blank. I'm not trying to insult you, but there must be. And it makes it hard for anyone to help when there is no code to look at. |

Ive coded for over 2 years in PHP and I can tell you nothing is wrong. Even this simple code does not work.
| Code: |
<?php
$num = 3
if($num == 3){
echo('Hi');
}else{
echo('Bye');
}
?> |
Even that doesnt work, all coding works until I use IF and ELSE or even just IF. |

If you add the ; to the line
$num = 3
it works. |

Why don't you try to use debuging in the php part. Just go to your php.ini file and change
display_errors = Off
to On
so that you can see where the errors are. Since your sample code had an error, maybe there might be an error will just pop up. Without having the real code to look at, it is impossible for anyone else to see what could be wrong.
By the way, if you correct your sample code and run it does it work?
There is also a log file in the php folder where the errors are stored. You might want to look in there to see if there isn't a function that isn't turned on that needs to be turned on. |

What you need is to gather more information about the problem. PHP will never tell you what's wrong if you haven't asked it. To do that you can edit php.ini (as mentioned earlier by dale) or this:
| Code: |
<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
// rest of your code here...
?>
|
You might also be interested in http://php.net/ini_set and http://php.net/error_reporting
I strongly recommend when you write code, to have error_reporting set to E_ALL (so you will be informed about all errors ie undefined variables etc...) and display_errors = On. Do that only on your local server and not on a live webserver because if an attacker can see these information, he/she might be able to hack your application. Be careful with these things.
Hope that helps. |
