form element values

[gr3gg0r]

How do you keep a form element's value between submissions? Thanks!

Well is this e.g. when a form hasnt been filled out correctly results are redisplayed?

If so there isnt a function so to say for it however, you can do something like this

if (!isset($_POST['submit']))
{
    // show normal empty form
}
else
{
    //check form if invalid reshow form
    if (forminvalid) //just an example forminvalid isnt even valid itself
    {
        //reshow form except using $_POST['formname'] in the values
    }
    else
    {
        //ok form filled in correctly do what is required
    }
}

Otherwise, if the form data is submitted, and you want to use that info for other forms, or you want to do a server-side check on the data:

You can echo the actual variable as a value in form elements:
<input type="text" value="<?php echo $SubmittedVar;?>" name="SomeName">

Of you can indlude them as hidden var's in the next form:
<input type=hidden name= value=>

Or you can after submission include them into session variables (eg write a small function which will check whether a POST array exists, and, if the variables match against a predefined set of allowable names & types, automatically include them in hte session array.
