Date regex

[Kemik]

Hello all,

 

I'm trying to create a regex which only allows dates in the following format:

 

dd-mm-yyyy

 

So I can insert it in to my database (DATETIME).

 

		if(!eregi("(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d", $str)) {
		$this->validation->set_message('datetime', 'The %s field must be in this format: dd-mm-yyyy');
		return FALSE;
	} else {
		return TRUE;
	}

 

If I try it, I get the error The datetime field must be in this format: dd-mm-yyyy.

 

Can anyone see where I'm going wrong? Thanks.

EREG does not understand \d, this is a PREG feature. Also, there's no need to use case-insensitive matching with digits and punctuation.

<?php

$pattern = "/((0[1-9])|(1[0-9])|(2[0-9])|(3[0-1]))\-((0[1-9])|(1[0-2]))\-[1-9][0-9][0-9][0-9]/";

$value = "19-09-2007";

if(preg_match($pattern,$value)){
echo "Valid";
}else{	
echo "Invalid";
}
?>
