Question

I have a simple MySQL 5 database that consists of

• id – Int – Primary Key
• userID – int
• projectId – int
• note – varchar (120)

And a simple Flex 4.5 app that I need to search the userID table for all rows belonging to a certain userID and return it to the Flex app. I’m using the default ZendAMF for my remoting. Currently my class looks like:

public function getAllBookmarksByUser($userId) {

        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE userId=?");     
        $this->throwExceptionOnError();

        mysqli_stmt_bind_param($stmt, 'i', $itemID);        
        $this->throwExceptionOnError();

        mysqli_stmt_execute($stmt);
        $this->throwExceptionOnError();

        $rows = array();

        mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);

        while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);
        }

        mysqli_stmt_free_result($stmt);
        mysqli_close($this->connection);

        return $rows;
    }

But, it’s not working. Not returning any objects when I test it in Flash Builder 4.5 even though I know the entries are in the db.

What am I doing wrong?

Edit
P.S. – This is an Adobe Air mobile app…

Edit

I’m adding a PHP class within the same file that is working perfectly as well. Here is the full file:

<?php

/**
 * Get 
 */
class BookmarksService {

    var $username = "*SQLUserName";
    var $password = "*SQLUserPassword*";
    var $server = "*MySQLServerURL*";
    var $port = "3306";
    var $databasename = "mscoast";
    var $tablename = "bookmarks";

    var $connection;

    /**
     * Connect
     */
    public function __construct() {
        $this->connection = mysqli_connect(
                                $this->server,  
                                $this->username,  
                                $this->password, 
                                $this->databasename,
                                $this->port
                            );

        $this->throwExceptionOnError($this->connection);
    }

    /**
     *Get All
     */
    public function getAllBookmarks() {

        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename");        
        $this->throwExceptionOnError();

        mysqli_stmt_execute($stmt);
        $this->throwExceptionOnError();

        $rows = array();

        mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);

        while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);
        }

        mysqli_stmt_free_result($stmt);
        mysqli_close($this->connection);

        return $rows;
    }


    /**
     * Get All By User ID
     */

public function getAllBookmarksByUser($userId) {

        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE userId=?");      
        $this->throwExceptionOnError();

        mysqli_stmt_bind_param($stmt, 'i', $itemID);      
        $this->throwExceptionOnError();

        mysqli_stmt_execute($stmt);
        $this->throwExceptionOnError();

        $rows = array();

        mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);

        while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->id, $row->userId, $row->projectID, $row->note);
        }

        mysqli_stmt_free_result($stmt);
        mysqli_close($this->connection);

        return $rows;
    }


    /**
     * Utility function to throw an exception if an error occurs 
     * while running a mysql command.
     */
    private function throwExceptionOnError($link = null) {
        if($link == null) {
            $link = $this->connection;
        }
        if(mysqli_error($link)) {
            $msg = mysqli_errno($link) . ": " . mysqli_error($link);
            throw new Exception('MySQL Error - '. $msg);
        }       
    }
}

?>

The first function works perfectly. Returns all of the rows. The second, gives no rows…

Also, here are my requests and responses from Flash Builder 4.5 (may or may not be of some use):

Answer 1

Sorry if this has been solved, but is this because you are providing ($userID) to the function but binding a different variable? ($itemID)

getAllBookmarksByUser($userId)

mysqli_stmt_bind_param($stmt, ‘i’, $itemID)
