[RESOLVED] Weird $_GET problem

mattm591

Hi,
I've been writing a script that was working fine for ages and I've been working on it today and made an edit and now it has the strangest problem.

The top of the code looks like this

<?
//add.php

//See if a certain type style is being used
$type=$_GET['typeselect'];

//If there isn't one set it to a default of "paper" to prevent errors later
if ($type==""){
$type="paper";
}

which was working fine and now all of a sudden it always seems to think that $type is blank.

However, if I put echo ("any text") before or after the $type line it works again!

Does anyone have any idea why that is or how to solve that cus I'm stumped!

Thanks,
Matt

edit: Just wanted to add, it doesn't even work if i put echo ""

I also have a second problem i thought i'd post here instead of starting a new topic.

How can I change what is stored in a $_POST variable so that when the form is refreshed new information is sent?

This may not solve your first problem, but typically we check if the incoming variable is set before we use it:

<?php
//add.php

//See if a certain type style is being used
//If there isn't one set it to a default of "paper" to prevent errors later
$type = "paper";
if (isset($_GET['typeselect']) && strlen($_GET['typeselect']) > 0) {
    $type = $_GET['typeselect'];
}

Alternatively, you can use [man]empty/man

Not sure what you mean. Perhaps you mean that you want the information entered to be stored between page loads? You can do this by checking if the incoming variables exist, and then set the form elements to them if necessary.

Thanks for that, my first problems solved 😃

I have found a workaround for my second problem as I don't think what i wanted was possible.
