Check if at least one checkbox is checked in PHP

Question

I already found a question called "Check if at least 1 checkbox is ticked in PHP", but that did not meet my needs because I am an organized person and that didn't seem like an organized way of doing it. I have this checkbox code:

    _________
   Which records would you like to see?

   Enter as little or as many criteria as you want and then press Submit.
   
     
       
         Last Name
         
       
       
         First Name
         
       
       
         Company
          
";
           print "            
";
           while ($row = mysql_fetch_array($result)) {
             print "            
";
           }
           print "          
";
         ?>
       
       
         Account type
          
";
           print "            
";
           while ($row = mysql_fetch_array($result)) {
             print "            
";
           }
           print "          
";
         ?>
       
       
         Product Name
          
";
           print "            
";
           while ($row = mysql_fetch_array($result)) {
             print "            
";
           }
           print "          
";
         ?>
       
       
         Share Type
          
";
           print "            
";
           while ($row = mysql_fetch_array($result)) {
             print "            
";
           }
           print "          
";
         ?>
       
       
         Closed?
          
";
           print "            
";
           while ($row = mysql_fetch_array($result)) {
             print "            
";
           }
           print "          
";
         ?>
       
       
         Value Greater Than $
         
       
       

    What columns would you like to show? (Note if none are checked none of the below will be shown.)
           
             
               Company
              
              
               Account #
              
              
               Contract Date
              
              
               Closed?
              
              
                Date Closed
             
              
                DOB
              
              
                Product Name
              
              
                Commission %
              
              
                Commission Payout (%)
              
              
                Commission Payout ($)
              
              
                Trail Comm?
              
              
                Guarantee %
              
              
                Account Type

The form submits to a page called validation.php and this is the code for that page (I hardly have anything yet):

I would like to delete the HTML special characters, instead of changing them, I would also want the First Name and Last Name to only have one capital letter by just telling the user, and if they don't I want the SQL to be able to validate with the First Name or Last Name being all capital or something crazy like that. I also want the First Name and Last Name to have all there space(s), if there are any. I want there to be at least one checkbox checked. I also want there to be a positive number that is a number in the number textbox.

I'm not sure what you are trying to do, but here is my guess code:

  if(isset($_GET['showcolumnxx']) || isset($_GET['showcolumnxx']) || isset($_GET['showcolumnxx'] || etc.))  {
  $newUrl = "http://something.site.end/otherpageshere/[screenAfterValidation].php";
  header('Location: ' . $newUrl);
    } else {
       print "You must at least check one checkbox.
";

    }
