I am using PHP to program a page that loops through to see how many items I have set on the backend. It performs a while loop to show the inputted number of items set on the backend. It starts like this:
 <? $cnt = $row->numberofitems + 1;
      $i = 1;
      while($i < $cnt)
      {
      $queryb = "SELECT * FROM table;

So I might have 3 form fields added or whatever number is set. My question is how can I set these up to be required. I am using javascript to check required fields and the code is shown below:

function MM_validateForm(){
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
if (document.contactfrm.fname.value == ''){
errors+='-First name is required.\n';
}
if (document.contactfrm.lname.value == ''){
errors+='-Last name is required.\n';
}
if (document.contactfrm.email.value == ''){
errors+='-Email address is required.\n';
}
if (errors)
alert ('The following errors occured:\n'+errors);
document.MM_returnValue = (errors == '');
}
//-->
