Displaying a Custom Error Message??

[The-Ensemble]

In the admincp file for the hack I'm doing, if the foreach functions return empty it returns

Warning: Invalid argument supplied for foreach() in /admincp/X.php on line 67

How could I change that to display a html wrapped message customized by me? Such as 'This Section Currently Has No Information' ?

Thanks. :up:

Check if the array you're looping has any data beforehand.

Nope, empty. I normally would of thought it'd be something like

PHP Code:


if(empty($var))
{
error message
} 


But I've no idea how to apply that to a foreach and Its not a variable.

Look in the vBulletin AdminCP files and see how they display their errors, then just duplicate this in your conditional. (They use fetch_error() and another function print_cp_message(), I think) Look them up in the API manual: vBulletin 3.6 Code Documentation.

You may have to create a phrase the "Error Messages" Phrasegroup.

If it's not a variable, then it can't be applied with the foreach language construct. That's what's giving you the error. If the supplied var is empty, foreach just skips it.
