now i use dreamweaver cs5 and it says no syntax errors, when i type the exact link into page it come up with two errors

 

firstly

 

Notice: Undefined variable: product_list in C:\wamp\www\myNewweb\storeadmin\inventory_edit.php on line 125

 

but i defined it quite clearly.

 

so on the inventory_edit page i deleted the line

 

 

<?php echo $product_list; ?>

 

 

and it worked! have i done this right, because i do not want it to hit me later in this database.

As with another persons post, i have a hard time reading through this to know exactly what everythings doing, however it seems as though in inventory_edit.php you have not defined $product_list anywhere.

 

in inventory_list.php you have, but inventory_edit is seperate and cannot access that variable's contents, thus making undefined. (unless im missing an include() somewhere in inventory_edit where you've brought this info over from inventory_list??)

 

 

I suggest making this whole block of code, it's own public function that you can use to retrieve your list:

 

<?php
function getProductList() {
//This block grabs the whole list for viewing
$product_list = "";
$sql = mysql_query("SELECT * FROM products");
$productCount = mysql_num_rows($sql);//count the the output ammount
if ($productCount > 0){
while($row = mysql_fetch_array($sql)){
$id = $row["id"];
$price = $row["price"];
$product_name = $row["product_name"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_Added"])); // Notice here how we changed it from _added to _Added
$product_list .= "$id - $product_name -  £$price -  $date_added    <a href='inventory_edit.phppid=$id'>edit</a>••<a href='inventory_list.php?deleteid=$id'>  delete</a><br/>";
}

}else{
$product_list = "You have no products listed in your store Yet";

}

return $product_list;
}
?>

 

 

then in inventory_edit call the function:

 

<h2>Inventory List</h2>
<?php echo getProductList(); ?>
</div>

 

and call the function the same way in inventory_list as well to clean things up.

 

 

Summed up, it appears inventory list has the variable declared, but inventory_edit does not. Hope this helps.
