[FX.php List] A little help with strings and arrays

[Steve Bennett]

Well it has been a fairly productive day building and testing  
checkboxes and the "\r\n" is working well but now I get the following  
two error lines when the user does not check any of the values which  
I assume returns an empty array which can not be imploded.

Notice: Undefined index: category in /Users/webuser/Sites/ 
ManagerSiteTest/managersitetest/add_result.php on line 4
Warning: implode() [function.implode]: Bad arguments. in /Users/ 
webuser/Sites/ManagerSiteTest/managersitetest/add_result.php on line 4


So my ready today has been about isset which I am thinking I can to  
use to check if the array should be imploded.

The current code which works without error as long as their are no  
empty arrays:
$add_result_fields = array('name'=>$_POST['name'],'category'=>implode  
("\r\n",$_POST['category']),'amount'=>$_POST['amount'],);

I have been trying change:

'category'=>implode ("\r\n",$_POST['category'])

To use isset to check if there is data in the $_POST['category']  
variable and implode it.

'category'=> if(isset($_POST['category'])){implode ("\r\n",$_POST 
['category'])}

but I get the following error:

Parse error: syntax error, unexpected T_IF

Thanks,

Steve
