In opencart, I have a variable sales_representative in a foreach loop. It gets defined and put into an array, then gets out-put in a .tpl file. Everything works as it should. But I get a notice up top saying undefined index: sales_representative... If it was undefined I wouldn't be getting a result displayed... Any thoughts?
Make sure before you give it any value, initialize it first outside the loop by giving it a value of either 0 or ""

I'm trying to add two $_POST variables, like so:
$points = $_POST['old_points'] + $_POST['new_points'];
(Line 48)
Which works fine, except it produces the following error:
Notice: A non well formed numeric value encountered in F:\xampp\htdocs\test\index.php on line 48
I can't figure out what the problem is here.
may be you need convert the content of $post as a correct number
$points = floatval($_POST['old_points']) + floatval($_POST['new_points']);

I am running an php website in xaamp server and while running i am getting this error, what does it means? and how do i solve this?
Undefined variable: _SESSION in C:\xampp\htdocs\web\Movie\admin.php on line 56
It most likely means you need to add session_start(); to the very top of your php page.
It means you are referencing the _SESSION variable without declaring it anywhere. Go to line 56 in your admin.php file to locate the reference. Once you find the reference you can then decide where to place the session_start() function call in your code to initialize _SESSION
For more info on session variables and _SESSION visit the PHP documentation page here.

My page returns this error:
Fatal error: Call to undefined function session_set()>in /home/a7714221/public_html/index.php on line 5
My code is long on the page that returns the error but the only thing that could cause it of course is the session_set()
Anybody know the fatal error that I've inadvertently made? :)
EDIt: I'm trying to pass variables across several pages. Specifically, take $_POST data, subtract it from another variable then ask the user to enter another value and subtract it from (previous post data - afore mentioned variable) and so on until it reaches 0.
There is no function session_set(), hence the fatal error. You tried to call a function that does not exist.
To set a session variable, you access it via the $_SESSION array.
So to set a $_SESSION variable, just like any other array
$_SESSION['foo'] = 'bar';
# Access a session var
echo $_SESSION['foo'] # Prints 'bar'

Helo there...
I inserted an Update Record form in Dreamweaver to update the category data on MySQL.
The line of coding below is what is giving me the problem.
<?php echo htmlentities($row_categoryedit['strdiscription'], ENT_COMPAT, 'uft-8'); ?>
If it is included the page gives me an internal server error.
If it is excluded the page works, but it dose not update the record.
Also when I preview it live it shows that there is errors on these 2 lines...
if (isset()) {
$varCategory_categoryedit = ;
Am I missing something or doing something wrong?
you must have a variable in isset() function.
example:
if(!isset($varCategory_categoryedit)){
$varCategory_categoryedit = "1";
}
