Variable Mysteriously Stops Echoing

Expand Post »

Hi,

I'm working on a page that GETs a value that is passed in the URL. This variable echos correctly up until I try echoing it inside an if statment where it needs to be.

The variable is called $siteid. Inside my if statement I have a query that runs WHERE id='$siteid'

Inside this if statement it won't echo out. It is the weirdest thing. I tried to hardcode the siteid as 95, to test it, and the query updated my database as it should. However, leaving it as the variable it will not work. Any help solving this mystery that I've been banging my head over for hours would be greatly appreciated!

My variable echos correctly up until the line that says:
// $siteid will Echo up until here. After this point it stops working.

The query I am having issues with is after the line that says:
// Problem lies in this query.

My SQL Table:
id int(11) No
userid int(11) No
url varchar(2083) No
credits int(11) No 0
dailyviews int(11) No 0
todayviews int(11) No 0
totalviews int(11) No
active tinytext No
title varchar(50) No
confirmed tinytext No

And my code:

$loginstatus = "logout";
 
$username = $_SESSION['username'];

Re: Variable Mysteriously Stops Echoing

It sounds like you are INITIALLY arriving at the page via editsites.php?siteid=95 , in which case line 11 works as expected. BUT your FORM does not "save" that siteid, so when you submit/POST the form, it is going to editsites.php, NOT to editsites.php?siteid=95.

So add the site id to your FORM's action:

PHP Syntax (Toggle Plain Text)

<form action="editsites.php?siteid=<?php echo intval($_GET['siteid']);?>" method="post"...>
