how to catch an error message

[zozzen]

Hi,

I'm using a CMS and a bunch of plug-in, but an error message sometimes mysteriously displays, possibly due to the crash with other plug-ins.

Although I don't really know what happens, the website still works fine.

To make it simple, I'm wondering if it's possible to "un-display" the error message like this?

Notice: Undefined variable: RecentLink in D:\xampp\htdocs\wiki\extensions\example.php

Any advice is appreciated!

According to your example it isn't a full-fledged error but a notice which is confirmed by you saying the pages still display as intended so you could add this simple snippet of code at the very top of a page above the html...

<? php error_reporting (E_ALL ^ E_NOTICE); ?>

That will not suppress actual error messages which I don't think you would want to do but it will suppress NOTICE messages such as the one you used in your example.

Or if you wanted to suppress purely that warning, put an @ sign before the variable on the particular line that's reporting the warning

$var to @$var

TBH, that doesn't look like a "crash with other plug-ins". It looks like either the developer has not anticipated this situation or has developed the code with E_NOTICE's turned off (which is what SevenCubed's post does).

The code still 'works' because PHP will default the value of $RecentLink if it is not defined.
