Please help,

This code is giving me the warning stated in the above given Subject line. And combo box is also not populating.

Code: [Select]
function populatecombo()
{
$dropdown = "";
$sqlcmb = "select wardno from wards";

mysql_query($sqlcmb) or die(mysql_error('Unable to query the table'));

while($row = mysql_fetch_assoc($sqlcmb)) {
$dropdown .= "\r\n<option value='{$row['wardno']}>'{$row['wardno']}</option>";
}
echo $dropdown;
}

This has been really annoying me for 2 hours now . I know its something silly

Any help is deeply appreciated

thanks

Ive been having trouble. Im getting this error:
Code: [Select]
$select = mysql_query($query1);
echo $select;
$rows1 = mysqli_fetch_array($dbc, $select);
I dont understand whats wrong.

Hey, this is my first post here, so bear with me: I'm new to PHP, and am trying to make an online store, right now I'm just making an admin inventory management, and so I'm using PHP to link to the database. 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? Thanks
