Form Fields Error

[therealairness]

Hi,

My form goes to another php page for validation when you click on submit. If there is a mistake, it goes back to the previous form. The problem is that every entries on the form disappears. Is there a way to save those mistakes?

Thanks.

Sure. The idea is to take the data from the refering page, validate it, if an error, pass the data back to the originating form.

// page1.php
<form action="action.php" method="post">

<?php

if ( isset($_GET['myData']) )
    echo "<input type=\"text\" name=\"myData\" value=\"$_GET[myData]\">";
else 
    echo "<input type=\"text\" name=\"myData\">";

?>

<input type="submit" name="formSubmitted">
</form>

// action.php
<?php
if ( isset($_POST['formSubmitted']) )
{
    if ($_POST['myData']  == "yes")
    {
        header("location: page1.php?myData=$_POST[myData]");
        exit();
    }
    else
        header("location: page1.php");
}
?>

If the user enters "yes" into the textbox, and then submits the form, it will still have the word "yes" in it. The key is to pass around the form data using $_POST/$_GET arrays, or using sessions. I'd recommend sessions becasue it gives you an easy way to maintain state within your applicaton.

How about if your form has lots of fields like an excel spreadsheets? You can update many rows and fields at once.

You would need to pass the data from each field back to the referring page.
