Retrieving items from a database table and adding them to an existing session array - My Forums

Retrieving items from a database table and adding them to an existing session array

Twobears — Apr 25, 2013, 12:03 AM

I have a shopping cart in Evo 1.0.8.
In the code block below, between lines 32 to 44, I am trying to retrieve the 4 items from a row in a table in the database and add them to the session array created at lines 22 to 28. Without the added code (32 to 44) the file works fine, however with the code added nothing is returned and the cart is empty.
Any help to show me where my error is would be appreciated.

// [[orderDetailsInToSESSION]]

if ( empty($_GET['customer']) ) return "no customer account specified";
else {
    // sanitize and validate the input type to make sure it's what you are expecting;
    $customer = $modx->db->escape($_GET['customer']);
    $orderId = $modx->db->escape($_GET['orderId']);
    // get the details from the orderId
    $db_query = $modx->db->select("productId, quantity", $modx->getFullTableName('customer_order_details'), "orderId='" . $orderId . "'");
    if ($modx->db->getRecordCount($db_query) > 0) {
        while ($row = $modx->db->getRow($db_query)) {
            // get the current prices and names of the products previously ordered
            $document_tvs = $modx->getTemplateVars(array("pagetitle", "price", "specialPrice"), "name", $row['productId']);

         // to put the returned array into a simpler/easier to use array use the following
               if (is_array($document_tvs)) {  
               foreach( $document_tvs as $document_TV) {
                $docTVArray[$document_TV['name']] = $document_TV['value'];
               }
              }

          // put these details into the session
         $_SESSION['shoppingCartContents'][] = Array (
              'productId' => $row['productId'],
             'productTitle' => $docTVArray['pagetitle'],
              'price' => ( !empty( $docTVArray['specialPrice']) ) ?  $docTVArray['specialPrice'] :  $docTVArray['price'],
              'quantity' => $row['quantity']
          );
        }
	}
		
	// if the productId is 219 get the 4 items in the row and add to session array
		if ($_SESSION['shoppingCartContents']['productId'] == 219) {
		$db_query = $modx->db->SELECT("hummusOne, hummusTwo, mayo, jam", $modx->getFullTableName('customer_order_giftpack_details'), "orderId='" . $orderId . "'");
		if ($modx->db->getRecordCount($db_query) > 0) {
                  while ($row = $modx->db->getRow($db_query)) {
		    $_SESSION['shoppingCartContents']['hummusOne'] => $row['hummusOne'],
		    $_SESSION['shoppingCartContents']['hummusTwo'] => $row['hummusTwo'],
		    $_SESSION['shoppingCartContents']['mayo'] => $row['mayo'],
		    $_SESSION['shoppingCartContents']['jam'] => $row['jam']
             );
	   }
        }

Glad it helped

If that is the entire snippet here is a slightly condensed version I put together (untested) that might work if you're interested:

// [[orderDetailsInToSESSION]]

if ( empty( $_GET['customer'] ) ){

    return "no customer account specified";

}else{

    // sanitize and validate the input type to make sure it's what you are expecting;
    $customer = $modx->db->escape( $_GET['customer'] );

    $orderId = $modx->db->escape( $_GET['orderId'] );

    // get the details from the orderId
    $order_details = $modx->db->getRow( $modx->db->select( 'productId, quantity', $modx->getFullTableName( 'customer_order_details' ), 'orderId="' . $orderId .'"' ) );

    if( $order_details ){
    
        // get the current prices and names of the products previously ordered
        $doc_tvs = $modx->getTemplateVars( array( 'pagetitle', 'price', 'specialPrice' ), 'name', $order_details['productId'] );

        // put these details into the session
        $_SESSION['shoppingCartContents'][] = Array (
                'productId'     => $order_details['productId'],
                'productTitle'  => $doc_tvs['pagetitle'],
                'price'         => ( !empty( $doc_tvs['specialPrice'] ) ) ?  $doc_tvs['specialPrice'] :  $doc_tvs['price'],
                'quantity'      => $order_details['quantity']
                );

        // if the productId is 219 get the 4 items in the row and add to session array
        if( $order_details['productId'] == 219 ){

            $items = $modx->db->getRow( $modx->db->select( 'hummusOne, hummusTwo, mayo, jam', $modx->getFullTableName( 'customer_order_giftpack_details' ), 'orderId="' . $orderId .'"' ) );

            if( $items ){

                $_SESSION['shoppingCartContents'][0]['hummusOne'] = $items['hummusOne'];
                $_SESSION['shoppingCartContents'][0]['hummusTwo'] = $items['hummusTwo'];
                $_SESSION['shoppingCartContents'][0]['mayo']      = $items['mayo'];
                $_SESSION['shoppingCartContents'][0]['jam']       = $items['jam'];

            }
        }
    }
}

I find I much prefer using hummus in tuna salad or egg salad than mayo, but it doesn't work at all for coleslaw!

Hi Breezer
Thanks for your help with this. Used your suggestion with a slight modification. Success, many thanks.

// if the productId is 219 get the 4 items in the row and add to session array
if ( $_SESSION['shoppingCartContents'][0]['productId'] == 219 ) {
 
    $items = $modx->db->getRow( $modx->db->select( 'hummusOne, hummusTwo, mayo, jam', $modx->getFullTableName( 'customer_order_giftpack_details' ), 'orderId="' . $orderId .'"' ) );
 
    if( $items ){
     
        $_SESSION['shoppingCartContents'][0]['hummusOne'] = $items['hummusOne'];
        $_SESSION['shoppingCartContents'][0]['hummusTwo'] = $items['hummusTwo'];
        $_SESSION['shoppingCartContents'][0]['mayo']      = $items['mayo'];
        $_SESSION['shoppingCartContents'][0]['jam']       = $items['jam'];
     
    }
 
  } // end of product219 if

Give this a try:

    // if the productId is 219 get the 4 items in the row and add to session array
    if ( $_SESSION['shoppingCartContents']['productId'] == 219 ) {

        $items = $modx->db->getRow( $modx->db->select( 'hummusOne, hummusTwo, mayo, jam', $modx->getFullTableName( 'customer_order_giftpack_details' ), 'orderId="' . $orderId .'"' ) );

        if( $items ){
        
            $_SESSION['shoppingCartContents']['hummusOne'] = $items['hummusOne'];
            $_SESSION['shoppingCartContents']['hummusTwo'] = $items['hummusTwo'];
            $_SESSION['shoppingCartContents']['mayo']      = $items['mayo'];
            $_SESSION['shoppingCartContents']['jam']       = $items['jam'];
        
        }

    } // end of product219 if
