Question

I have a big form

This form is processed by a PHP file called by a serialize jQuery function

foreach($_GET['claimant'] as $k=>$v) {
$insClaim = "INSERT INTO `cR_Claimants` (`memberID`, `ParentSubmission`, `Name`, `DOB`, `Company`, `Email`, `MainPhone`, `OtherPhone`, `MobilePhone`, `OwnershipPercentage`, `Address`, `ZIPcode`, `Country`) VALUES ('".$memberID."', '".$refNumb."', '".mysql_real_escape_string($v['name'])."', '".$v['DOB']."', '".mysql_real_escape_string($v['company'])."', '".$v['email']."', '".$v['mainPhone']."', '".$v['alternatePhone']."', '".$v['mobilePhone']."', '".mysql_real_escape_string($v['percentage'])."', '".mysql_real_escape_string($v['address'])."', '".$v['ZIP']."', '".$v['country']."')";
$resultinsClaim=mysql_query($insClaim) or die("Error insert Claimants: ".mysql_error());
}

The problem is that $_GET['claimant'] in certain cases can be empty. I mean that the relative field has not been entered at all.

When this happens obviously the Insert should not run when that specific $_GET['claimant'] is empty.

I tried the two following solutions, but they do not work, the Insert runs anyway, putting in my DB empty strings.

Please help.

foreach($_GET['claimant'] as $k=>$v) {
if($_GET['claimant'] != "") {
$insClaim = "INSERT INTO `cR_Claimants` (`memberID`, `ParentSubmission`, `Name`, `DOB`, `Company`, `Email`, `MainPhone`, `OtherPhone`, `MobilePhone`, `OwnershipPercentage`, `Address`, `ZIPcode`, `Country`) VALUES ('".$memberID."', '".$refNumb."', '".mysql_real_escape_string($v['name'])."', '".$v['DOB']."', '".mysql_real_escape_string($v['company'])."', '".$v['email']."', '".$v['mainPhone']."', '".$v['alternatePhone']."', '".$v['mobilePhone']."', '".mysql_real_escape_string($v['percentage'])."', '".mysql_real_escape_string($v['address'])."', '".$v['ZIP']."', '".$v['country']."')";
$resultinsClaim=mysql_query($insClaim) or die("Error insert Claimants: ".mysql_error());
}
}

AND

foreach($_GET['claimant'] as $k=>$v) {
if(!empty($_GET['claimant'])) {
$insClaim = "INSERT INTO `cR_Claimants` (`memberID`, `ParentSubmission`, `Name`, `DOB`, `Company`, `Email`, `MainPhone`, `OtherPhone`, `MobilePhone`, `OwnershipPercentage`, `Address`, `ZIPcode`, `Country`) VALUES ('".$memberID."', '".$refNumb."', '".mysql_real_escape_string($v['name'])."', '".$v['DOB']."', '".mysql_real_escape_string($v['company'])."', '".$v['email']."', '".$v['mainPhone']."', '".$v['alternatePhone']."', '".$v['mobilePhone']."', '".mysql_real_escape_string($v['percentage'])."', '".mysql_real_escape_string($v['address'])."', '".$v['ZIP']."', '".$v['country']."')";
$resultinsClaim=mysql_query($insClaim) or die("Error insert Claimants: ".mysql_error());
}
}

If $_GET[‘claimant’] is an array, you should ask for its length:

if (count($_GET['claimant']) > 0) { ... }
