PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens

Question

$sql = \'INSERT INTO `\' . $table_name . \'` \'
            . \'(`day`, `campaign_name`, `campaign_id`, `views`, `CPM`, `cost`, `currency`, `cost_EUR`) VALUES \'
                


        

Answer 1

You only need to pass an array to the execute method. So your updated code would look like this:

$sql = 'INSERT INTO `' . $table_name . '` '
            . '(`day`, `campaign_name`, `campaign_id`, `views`, `CPM`, `cost`, `currency`, `cost_EUR`) VALUES '
            . '(:day, :campaign_name, :campaign_id, :views, :CPM, :cost, :currency, :cost_EUR)';
$sth = $this->_dbi->prepare($sql);    
$sth->execute(array(
            ':day'        => $day,
            ':campaign_name'      => $campaignName,
            ':campaign_id'    => $campaignID,
            ':views'          => $views,
            ':CPM'        => $cpm,
            ':cost'     => $cost_EUR,
            ':currency'       => 'EUR',
            ':cost_EUR' => $cost_EUR
));

PDOStatement::execute — Executes a prepared statement

Usage: public bool PDOStatement::execute ([ array $input_parameters ] )

Here is the example from the documentation:

prepare('SELECT name, colour, calories
    FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->execute(array(':calories' => $calories, ':colour' => $colour));
