User chooses amount of text boxes

[superdan_35]

Hi all.

I am trying to make a form where the user enters the number of entries they wish to make into a textbox and that amount of new textboxes would automatically appear below. Any suggestions?

Thanks,
Dan

depending on your functionality, javascript or PHP with querystring values

Don't suppose you could give some starting point?

Thanks,

You are going to need to use JavaScript definitely unless you mean someone inputs a number of textboxs then submits it in a form in which case you could use something similar to:

$count = $_POST['count'];
while($count > 0)
{
echo "<textarea></textarea>";
$count = $count - 1;
}

as pudge points out the two options are:

1) ask them how many they want in a form, submit it and then either use $POST or $GET to get that number

if you use $_GET, the number goes in the url: index.php?cnt=5

in which case you'd do this to put put the boxes

<?php

if(exists($_GET['cnt']) and ctype_digit($_GET['cnt']))
{
     for ($i=0;$i<$_GET['cnt'];$i++)
     {
     echo '<input type="textbox" name="text'.$i.'"/>';
     }

}
?>

substitute $GET with $POST depending on which you set in the form asking how many boxes (note: in this example the variable 'cnt' assumes thats the name of the textbox in the form used to designate the # of boxes you want)

2) if you want to do it a bit fancier you can use javascript to dynamically grow the boxes in page in which case you'd have to visit the JS section

Sorry for the confusion. I am trying to do it dynamically through javascript.
