Question

I am working on a program in which information from a form is reprinted using an echo command. I had hoped for the user to be able to create a list by typing into the form, clicking submit, printing this to the screen, repeat. However, every time I click submit, the previously printed text is removed and printed over. How can I force it to print to the next line and not delete the previous lines. I am using:

echo $_POST['Field'];

To avoid using the server’s memory for saving the previous lines, you could use a hidden field.

Try something like this:

<form method="post" action="">
<input type="text" name="txtCurrentLine" />
<input type="hidden" name="hdnPreviousLines" value="<?php echo htmlentities($_POST['hdnPreviousLines'] . '<br />' . $_POST['txtCurrentLine']); ?>" />
<input type="submit" name="btnSubmit" value="Submit" />

You have entered: <br /><?php echo htmlentities($_POST['hdnPreviousLines'] . '<br />' . $_POST['txtCurrentLine']); ?>
