When the form is submitted, $_POST will have the value of the textbox. Then check if $_POST is in the array using in_array function. http://nl2.php.net/in_array
Then redirect if its in the array.

Member Avatar for farahphp

like write the code for validation in the page which its redirecting to or on the same page where onsubmit it calls a JS function and checks for validation?

Member Avatar for nav33n

Yeah.. something like that.. Simple example.

$id = $_POST['id']; //say the user has entered 10 in the form.
$checkarray = array("10","20","30");
if(in_array($id,$checkarray)){
// redirect.. $id found in the array
} else {
//redirect to error page $id not found in the array
}

I don't know.. Be specific about your question. What do you mean by no luck ? What is the problem ? My suggestion is, split your script into small parts and debug.
