A little help with $_POST

[DissObey]

I'm working on a little something and have hit a brick wall. The script requires users to input a number, which gets $_POST back to the page, the part im waving trouble with is to print a set code for the amount sent by the $_POST

E.g

You submit the value 5 in the input field the result you would get back would be

$result

$result

$result

$result

$result

I know its possible to do it with if statements .... if $_POST['num] == 1

but surely there is a more efficient way.

I actually started coding something to explain but what you put is very vague, and I'm not entirely sure what you are asking exactly.

The users submits a number to the script, say the number 5.

Then the script will print 5 dropdowns.

If the user submits the number 100 it should print 100 dropdowns

Re: A little help with $_POST

To see what was posted:

<?php
print_r($_POST);
?>

 

Say you post the field "num":

<?php
// Validate post
for ($i = 0; $i < $_POST['num']; $i++) {
echo 'bla
';
}
?>
