Question:
Hai.. i already added javascript validation for my form.Its working fine.But mean while i ve to validate the same form using PHP also.
This is the form code:
class airportclass{ function add_airport_frm(){ $errmsg=0; <table> <form action="" method="post" name="airport" > <tr> <td colspan="2" align="center"><?php echo $errmsg; ?></td></tr> <tr> <td><strong>Code :</strong></td> <td><input type="text" name="code" id="code" /></td> </tr> <tr> <td><strong>Name:</strong></td> <td><input type="text" name="name" id="name" /></td> </tr> </form> </table> } This is the PHP script in another file :
if(isset($_POST['postcode']) && $_POST['postcode']!="") { $code=$_POST['code']; $name=$_POST['name']; $postcode=$_POST['postcode']; $auth=$_POST['auth']; if(trim($code)=='') { $errmsg = 'Please enter code'; } } But its not working. Only javascript validation is working.PHP validation is not working.
Can any one suggest me????
Solution:1
As the form action="" is blank, the form is being posted to the same file. You indicated that you have your validation script in another file!
Solution:2
The $errmsg variable you're using is not global. It needs to be global if you intent to use it inside multiple functions.
Solution:3
You are checking against 'postcode', but postcode is nowhere set in your form.
