Question

I have an array that I created by this query:

$run=0;
$result = $conn->query("SELECT distinct isbn13 from inventory 
                        WHERE quantity>0 and isbn13 like '978%' limit $run, 20");

while($image = $result->fetch_assoc())
{
    $isbn[$x] = $image['isbn13'];  
    $x++;
} //end while

and I need to pass it into this function:

$parsed_xml = ProductId_xml($isbn);

I know there is information in the $isbn because I used print_r($isbn); and saw the array. However, when I do the same in the function (var_dump($searchterm); die;), I get NULL.
Here is part of the function:

count=0;

function ProductId_xml($searchTerm) {
    var_dump($searchTerm); die;

    $params = array(
        'AWSAccessKeyId' => AWS_ACCESS_KEY_ID,
        'Action' => "GetMatchingProductForId",
        'SellerId' => MERCHANT_ID,
        'SignatureMethod' => "HmacSHA256",
        'SignatureVersion' => "2",
        'Timestamp'=> gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time()),
        'Version'=> "2011-10-01",
        'MarketplaceId' => MARKETPLACE_ID,
        'IdType' => "ISBN",
    );

    $id=array(explode(',',$searchTerm));

    foreach ($id as $newId)
    {
        $count .= $count +1;    
        $params += array('IdList.Id.'.$count => $newId);
    } //end of foreach  

How do I get the information into my function?

Answer 1

The incoming variable $searchTerm should be an associative array. You don’t need to explode it. You should just be able to access the information by saying $searchTerm['key'] or by using a foreach loop.

foreach ($searchTerm as $key=>$val) { 
    $params['IdList.Id.'.$key] = $val;
} //end of foreach
