Question

I have a function below which works perfectly, but now the client came back and asked that the number only be taken to do the search because most of his clients won’t type in the suffix “h” or whatever it may be as per my example below:

38039 or 38039h

However he also said he only has one group of product codes which begin with “T” so they could be typing in “T760” in which case we would need the prefix.

My code below does a search on the exact product currently, can anyone help me work in these examples?

<?php 

//Find Stock Value
function checkstock($prodCode) { 

  $prodCode = strtoupper($prodCode);

  require '../../../../config.php';
  $dbh = new PDO(DB_DSN, DB_USER, DB_PASS);
  $sql = "SELECT * FROM isproducts WHERE prodCode = '".
         $prodCode."' AND AllowSalesOrder = '1'"; 
  $stmt = $dbh->query($sql);
  $obj = $stmt->fetch(PDO::FETCH_OBJ);

  $count = $stmt->rowCount();

  echo ($count == 1 ? 
   ROUND($obj->FreeStockQuantity, 0) : 'Invalid product code '.$prodCode.'');   

}

//Call Stock Function
checkstock($_POST['productcode']);

?>

Change the query to like below ?

SELECT * FROM isproducts 
WHERE 
  (
    prodCode='{$prodCode}'          // for product with prefix or suffix
    OR prodCode LIKE '{$prodCode}%' // without suffix
    OR prodCode='T{$prodCode}'      // without prefix
  )
  AND AllowSalesOrder = ''"; 

Wild-card by single character

 OR prodCode LIKE '{$prodCode}_' // single character wild-card
