PHP - Warning: Usort() Expects Parameter 2 To Be A Valid Callback
Probably missing something really stupid here. My usort function:
private function compareLastName($x, $y) { if($x['Name'] == $y['Name']) { return 0; } elseif ($x['Name'] < $y['Name']) { return -1; } else { return 1; } } is being called in this function, same file: public function loadAll() { //various SQL stuff $arrayNoNulls = $stmt->fetchAll(); //various SQL stuff $arrayNulls = $stmt->fetchAll(); $arrayAll = array_merge($arrayNoNulls, $arrayNulls); usort($arrayAll, "compareLastName"); print_r($arrayAll); } The page outputs the unsorted array, preceded by the warning. What am I missing? Similar TutorialsI am getting
set_exception_handler() expects the argument (static BugReporter::exception_handler) to be a valid callback in ....
The line is set_exception_handler(array('static BugReporter', 'exception_handler')); BugReporter is a class - eg
class BugReporter {
}
exception_handler is a function withing the class
I have no idea what is wrong. I haven't come across set_exception_handler() before
Can anyone see what is wrong - Thanks

Before any of this script, I link to the database and all that, so it's not an issue of connection. My issue is I keep getting the following message: Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in "inventory_list.php" on line 38 Column count doesn't match value count at row 1 There used to be three or four other error messages, but I've been able to work out my mistakes and fix them. Here is my code, starting at Line 27: Code: [Select] <?php // Parse the form data and add inventory item to the system if (isset($_POST['product_name'])) { $product_name = mysql_real_escape_string($_POST['product_name']); $price = mysql_real_escape_string($_POST['price']); $category = mysql_real_escape_string($_POST['category']); $subcategory = mysql_real_escape_string($_POST['subcategory']); $details = mysql_real_escape_string($_POST['details']); // See if that product name is an identicle match to another in the system $sql = mysql_query("SELECT product_id FROM products WHERE product_name='$product_name' LIMIT 1"); $productMatch = mysql_num_rows($sql); // count the output amount if ($productMatch > 0){ echo 'Sorry, you tried to place a duplicate "Product Name" into the system, <a href="inventory_list.php">click here</a>'; exit(); } // Add this product into the database now $sql = mysql_query("INSERT INTO product (product_name, price, category, subcategory, date_added) VALUES('$product_name','$price','$details','$category','$subcategory',now())") or die (mysql_error()); $pid = mysql_insert_id(); // Place image in the folder $newname = "$pid.jpg"; move_uploaded_file($_FILES['fileField']['tmp_name'], "../inventory_images/$newname"); } ?> The line causing this issue is thus: Code: [Select] $productMatch = mysql_num_rows($sql); // count the output amount Does anyone know how to fix this for me?
