Question

Is it possible to create multiple html text inputs on my

<form method="POST" id="2"> 

using:

<input type="text" value="">

with an initial value of none and fill it with a value after clicking submit from a previous

<form method="POST" id="1">

Can anyone help me with this?

Thanks in advance! By the way, I’m using PHP.

@zerey: I coded up this commented contrived example of what I think you might have been hoping to achieve using PHP only and I’ve combined it all into one form —

<?php
if (strtoupper($_SERVER['REQUEST_METHOD']) == "POST")
{
    $foo = intval($_POST['foo']);
    $bar = $_POST['bar'];

    if (count($bar) > 0)
    {
        // the additional inputs that were created now contains data
        // and furter validation can take place here
    }
}

if (!isset($foo))
{
    $foo = 0; // default the # of inputs field to 0
}
?>
<form action="<?php echo $_SERVER['SCRIPT_NAME']; ?>" method="post">
    <div>
        <label for="foo"># inputs:</label>
        <input type="text" name="foo" size="3" maxlength="1" value="<?php echo $foo; ?>">

        <input type="submit" value="Submit">
    </div>
    <?php
    // a check to limit the amount of additional inputs that can be
    // created
    if ($foo < 10 && $foo > 0)
    {
    ?>
    <div>
        <?php
        // loop to output the # of inputs the user previously entered
        for ($i = 0; $i < $foo; $i++)
        {
        ?>
        <br>
        <label for="bar[<?php echo $i; ?>]"><?php echo $i + 1; ?></label>
        <input type="text" name="bar[<?php echo $i; ?>]" id="bar[<?php echo $i; ?>]" value="<?php echo $bar[$i]; ?>">
        <?php
        }
        ?>
    </div>
    <?php
    }
    ?>
</form>
