RE: [PHP] Problem with header in an if SOLVED

[snip] /* check for errors */ $arrCheckItems = array( 'Name', 'Dept', 'Level', ); /* check for blanks */ foreach($_POST AS $key=>$value){ if(in_array(niceName($key), $arrCheckItems)){ $errorsReported[] = notBlank($key, $value); } } Even if the return from notBlank is nothing, $errorReported[] gets set for each item passed in the foreach loop. I have tried using conditional returns in the function, but to no avail. Perhaps my logic is screwed on this. [/snip] I changed to the following code and it solves the problem ... foreach($_POST AS $key=>$value){ if(in_array(niceName($key), $arrCheckItems)){ $nbr = notBlank($key, $value); if(!('' == $nbr)){ $errorsReported[] = $nbr; } } } Before I was directly assigning the value of the return from the notBlank function to $errorsReported. Now something only gets assigned to $errorsReported if there is something to assign.
