Network Mac Address validation

[somaskarthic]

Hi

Can anyone send javascript code to validate the
network mac address(eg. 02:41:6d:22:12: f1)
It accepts value from 00:00:00:00:00: 00 to
ff:ff:ff:ff:ff: ff.

On keypress event of textbox , i need to allow characters
0 to 9 , a to f , and : (colon).

On Clicking save button , script function should check the
format for valid mac address.

Text box length should be 17.

Pls post your replies.
Thanks in advance

Here you go buddy...

 function isValidMacAddress(macAdd) 
 {
  var RegExPattern = /^[0-9a-fA-F:]+$/;
  
  if (!(macAdd.match(RegExPattern)) || macAdd.length != 17) 
  {
   alert("Invalid Media Access Control Address");
  }
  else
  {
   alert(macAdd + " is a valid Media Access Control Address");
  }
 }

sorry, that's JS, i don't know if you wanted that. but easily convertable to PHP.

See: preg_match

3 standard (IEEE 802) formats:

* 0a:1b:3c:4d:5e: 6f
* 0a-1b-3c-4d-5e-6f
* 0a1b.3c4d.5e6f

<script type="text/javascript">

	teststr="0a:1b:3c:4d:5e:6f";
	
	regex=/^([0-9a-f]{2}([:-]|$)){6}$|([0-9a-f]{4}([.]|$)){3}$/i;
	
	if (regex.test(teststr)){
		document.write("Valid mac address");
	}
	else{
		document.write("Not a valid mac address");
	}

</script>
