does it only happens in your ads_title? or it also goes with some other field? ads_image........etc..

[gizmola]

A notice is not an error -- it is a "notice". 

 

It's very clear what the notice is telling you.

 

You are attempting to make a boolean evaluation using $error['ads_title'] however, this array element doesn't exist.

 

In a situation like this you can use isset() first to shortcircuit evaluation.

 

if (isset($error['ads_title']) && $error['ads_title'] != '') 

 

[Network_ninja]

Yep... exactly.. You cannot encounter that kind of notice when the version of your php is below 5.0

What does your postErrorCheck() function code do and should it return an array element for each form field?

[$php_mysql$]

friends it happening for all fields only when submited the form with value in it, i got the same code working on one of my other script which does not output any error at all, here is my function

 

function postErrorCheck($data){	
	   $errormsg = array();

	   if($data['ads_title'] == '') {
	   $errormsg['ads_title'] = 'Advertisement title is required!';
	   }else if(strlen($data['ads_title']) > 100) {
	   $errormsg['ads_title'] = 'Title cannot be more than 100 characters';
		}	


		return $errormsg;
}

Well the problem exists in the code, whether you happen to stumble upon it in testing or not.  If you try and access an element of an array that doesn't exist you'll get a notice, unless you either insure that it exists, or check using isset() to short circuit the access as I showed you.

[$php_mysql$]

yeah i did used isset and it did solve my error issue but still was wondering the same code works ok in other script but not in this

[gizmola]

Ok, well, as I stated previously it's not an error.  You can control the "level" of error reporting your site provides, and furthermore it should be logged and not displayed on a production site.  Really these notices exist to help you write really clean code, but in many cases, even if you don't write the cleanest level of code, you will not have issues.

 

See error_reporting

 

 

[$php_mysql$]

yes i have already notice that when i use error_reporting(1); or even error_reporting(0); i get no Notice message

[$php_mysql$]

anyways thanks mate, will just satisfy myself with the  error_reporting(0); :-)

[gizmola]

The setting you want:

 

error_reporting(E_ALL & ~E_NOTICE);

 

For a production server, you want your php.ini (depending on the php version) to set this either to be off, or to send to stderr.  You don't want to have to set this in your scripts.
