RE: [PHP] checking status of a HTML checkbox

My apologies for deficient terminology. I define a "regular post" as the original <form action=somewebpage.php method=post> with globals on and the somewebpage.php using the variable sent without using $_POST. But I bet you already knew that :) You asked for the code... My first page has ... ... echo "<form name=Search action=\"".$site."dest.html\" method=post>"; echo "<input type=text size=11 maxlength=11 name=search>"; ?> <br> <INPUT type=text size=3 name=SSN1 maxlength=3 onKeyUp=if(this.value.length==3)th is.form.SSN2.focus();> - <INPUT type=text size=2 name=SSN2 maxlength=2 onKeyUp=i f(this.value.length==2)this.form.SSN3.focus();> - <INPUT type=text size=4 name=S SN3 maxlength=4> </td> ... my second page has... ... if(isset($SSN1) ) { header( "Location: ".$site."newplace.html?SSN1=".$SSN1."&SSN2=".$S SN2."&SSN3=".$SSN3.""); } ... End result being that if they used the text input they would continue with the second page, skipping the new header. I could put a value in the text and leave SSN alone and get sent to the new header. If I put a value in SSN1 I would go to the new header. If I put the echo "hello"; before the header line and leave use the search text box leaving SSN1 blank I would not get the new header. If I used the SSN1 I would get hello and then an error message that the header had already been sent which is what I expected. However, upon removing the hello line again, it went right back to sending the new header whether SSN1 was used or not. Changing the if to reflect if($SSN1 > 0) it works as intended except that some SSN's have leading 0's for their first 3 digits so I am about to use empty(). The > 0 was a quick fix since they needed to use it immediately. PS you'll have to contend with "..." as these scripts 242 and 409 lines long respectively. I can assure you that the form is properly closed on the sending page though. Larry S. Brown Dimension Networks, Inc.

Well, the key is passed even when there's even though the field might be empty. > I have used isset with just receiving post data and got > strange results.
