PHP PDO Stopped Working

Question

I am running into a weird issue with PDO. Sometimes it just doesn't execute the SQL. But it acts like it does.

$SQL = 'INSERT INTO
beam_stats (beam_id, beam_stat_type, beam_stat_count)
                VALUES
                    (:BID, :BST, :BSC)
                ON DUPLICATE KEY UPDATE
                    beam_stat_count = beam_stat_count + VALUES(beam_stat_count)';
$parameters = Array(':BID' => $beamID, ':BST' => $valueName, ':BSC' => $value);
$this->dbCon->prepare_execute($SQL, $parameters);
    /**
     * Prepares and Executes the provided statement and parameters.
     *
     * @param string $statement
     * @param ARRAY $parameters
     * @return mixed database results
     */
    public function prepare_execute($statement, $parameters) {
        $this->prepare($statement);
        return $this->execute($parameters);
    }

    /**
     * Prepares the provided database statement
     *
     * @author  Jonathan Pitcher
     *
     * @param string $statement
     */
    public function prepare($statement) {
        $this->sth = $this->db->prepare($statement);

        if (!$this->sth) {
            error_log(print_r($this->db->errorInfo(), true));
        }
    }

    /**
     * Executes the prepared statement in sth using the passed parameters.
     *
     * @author Jonathan Pitcher
     *
     * @param ARRAY $parameters
     * @return mixed
     */
    public function execute($parameters) {
        $results = $this->sth->execute($parameters);
        $count = $this->sth->rowCount();
        error_log($this->sth->queryString);
        error_log("Updated $count rows.\n");
        if (!$results) {

            error_log(print_r($this->sth->errorInfo(), true));

            return false;
        }
        return $results;
    }

I log everything. So when it executes the logs print out what happens and how many rows got updated.

[Thu Jun 05 10:15:40 2014] [error] [client ] Updating Beam Stat 494 sold_out 1
[Thu Jun 05 10:15:40 2014] [error] [client ] INSERT INTO\n\t\t\t\t\t\tbeam_stats (beam_id, beam_stat_type, beam_stat_count)\n\t\t\t\t\tVALUES\n\t\t\t\t\t\t(:BID, :BST, :BSC)\n\t\t\t\t\tON     DUPLICATE KEY UPDATE\n\t\t\t\t\t\tbeam_stat_count = beam_stat_count + VALUES(beam_stat_count)
[Thu Jun 05 10:15:40 2014] [error] [client ] Updated 1 rows.\n

But when I check the database the line has not been inserted.

Now if I copy the SQL and the values and run it manually it works.

And if a record is already in there it works it will update the total. But it will not insert the record.

To make it even weirder this sql is a function used all over the site and it works with no issues anywhere else. Just this one scenario.

Answer 1

your parameter array is incorrect. It should be 'BID' , 'BST' , 'BSC' that is, drop the colon : for the parameter array.
