My intention is to retrieve data from a database and have created the following functions but receive an undefined function, grades, error message. The code is as follows:\[code\] <form action="processor.php" method="post"> <h4>Question # 1</h4> <p>What grade are you in?</p> <label class="checkbox"><input type="checkbox" name="grade" value="http://stackoverflow.com/questions/15846872/1"> Freshmen</label> <label class="checkbox"><input type="checkbox" name="grade" value="http://stackoverflow.com/questions/15846872/2"> Sophomore</label> <label class="checkbox"><input type="checkbox" name="grade" value="http://stackoverflow.com/questions/15846872/3"> Junior</label> <label class="checkbox"><input type="checkbox" name="grade" value="http://stackoverflow.com/questions/15846872/4"> Senior</label> <h4>Question # 2</h4> <p>What is your current GPA?</p> <select name="gpa"> <option value="http://stackoverflow.com/questions/15846872/4">3.5 or above</option> <option value="http://stackoverflow.com/questions/15846872/3">3.0-3.4</option> <option value="http://stackoverflow.com/questions/15846872/2">2.5-2.9</option> <option value="http://stackoverflow.com/questions/15846872/1">2.0-2.4</option> <option value="http://stackoverflow.com/questions/15846872/0">Lower</option> </select> <h4>Question # 3</h4> <p>Where do you excel the most academically?</p> <select name="school" multiple="multiple"> <option value ="http://stackoverflow.com/questions/15846872/1">Mathematics</option> <option value ="http://stackoverflow.com/questions/15846872/2">Literature</option> <option value ="http://stackoverflow.com/questions/15846872/3">History</option> <option value ="http://stackoverflow.com/questions/15846872/4">Humanities</option> <option value ="http://stackoverflow.com/questions/15846872/5">Science</option> </select>\[/code\]Then the PHP file that processes the form submission:\[code\]<?phprequire_once('processor.php');class Processor { #codefunction get_response($id) {$dsn = "mysql:host=localhost;dbname=user";$username = "root"; // database username$password = "stewie12"; // database passwordtry { $enter = new PDO($dsn, $username, $password); $sql = "SELECT response FROM recommendations WHERE id = ?
