I am trying to write a piece of code whereby a user inputs a number into a form. then, upon submission, the page will be refreshed to now contain the input number of new fields to be filled in.
eg - Please enter a number : 3
submit - page refreshed

Please enter a number : 3

- Please enter a new number : blank
- Please enter a new number : blank
- Please enter a new number : blank

any simple ideas ?

hodgy,

This might not necessarily be JavaScript, but perhaps PHP. On the first page, a form would exist allowing the user to select a number, 3 for example. Hit Submit which is directed either back to itself or another PHP file.

That PHP file would read the parameter from the form then use a FOR loop to create the specified number of inputs required.

yeah, i am starting to think along those lines as well, is it then possible to assign a php variable to the value of each new field created. i mean i would be creating fields in a loop so how can i give each field a different variable name ? is that possible ?

Sure. Here is an example creating text inputs but you can substitute for anything you want. I'm assuming that the number of controls to create (designated by the user from the previous screen) is called "userSelect."

PHP Code:


$num = $_POST[userSelect];

for( $i = 0;($i < $num); $i++ )
{
?>
    <input type="text" name="myinput<?= $i ?>" />

<?php

}

great ! thanks
