symfony doctrine query result and execute function - symfony1

Question

I have this doctrine query in symfony. It returns a lot of rows when i run mysql code generated by this dql query in phpBB but when i run it in symfony and access its results with this code:
foreach ($this->courses as $course){
echo "<br>".$course->firstname;}
it returns only one name. Also when i try to get $course->title, this error appears
Unknown record property / related component "title" on "Students"
Query:
$q= Doctrine_Query::create()
->select('s.firstname,
s.middlename,
s.lastname,
p.program,
c.title,
pc.year')
->from('Students s')
->leftJoin('s.Programs p')
->leftJoin('p.Programcourses pc')
->leftJoin('pc.Courses c')
->where("idstudents = ?",2);
$this->courses=$q->execute();

Answer 1

this is how i get it work...
$q= Doctrine_Query::create()
->select('s.firstname,
s.middlename,
s.lastname,
p.program,
c.title,
pc.year')
->from('Students s')
->leftJoin('s.Programs p')
->leftJoin('p.Programcourses pc')
->leftJoin('pc.Courses c')
->where("idstudents = ".$studentid);
//$this->query=$q->getSqlQuery();
$q->setHydrationMode(Doctrine_Core::HYDRATE_SCALAR);
$this->Student=$q->execute(array());
and in template
<?php foreach ($Student as $student): ?>
<tr>
<td><?php echo $i; ?></td>
<td><?php echo $student['c_title'] ?></td>
<td><?php echo $student['pc_year'] ?></td>
<td><?php echo $student['p_program'] ?></td>
</tr>
<?php endforeach; ?>

Answer 2

Your top node is the a Students object, because you use Students in the from()
Your error describe this
Also when i try to get $course->title, this error appears Unknown record property / related component "title" on "Students"
because you have a Students object, not a Courses one (where title belongs)
You are confusing yourself using
$this->courses=$q->execute();
$q= Doctrine_Query::create()
->select('s.firstname,
s.middlename,
s.lastname,
p.program,
c.title,
pc.year')
->from('Students s')
->leftJoin('s.Programs p')
->leftJoin('p.Programcourses pc')
->leftJoin('pc.Courses c')
->where("idstudents = ?", $studentid); // beware to SQL injection, use parameters
$this->Student=$q->fectchOne(); // as you are only retrieve one in your where clause
$this->Student=$q->execute()->getFirst(); // same
<tr>
<td><?php echo $i; /* not sure what this is for */ ?></td>
<td><?php echo $Student->Programs->Programcourses->Courses->title ?></td>
<td><?php echo $Student->Programs->Programcourses->year ?></td>
<td><?php echo $Student->Programs->program ?></td>
</tr>
If you want Courses to be the top, just go for something like:
$q= Doctrine_Query::create()
->select('s.firstname,
s.middlename,
s.lastname,
p.program,
c.title,
pc.year')
->from('Courses c')
->leftJoin('c.Programcourses pc')
->leftJoin('pc.Programs p')
->leftJoin('p.Students s')
->where("s.idstudents = ?", $studentid);

Answer 3

A few things:
Instead of $course->firstname and $course->title, you want $course->getFirstName() and $course->getTitle().
You should use singular names for your tables instead of plural, e.g. Course instead of Courses.
The convention in symfony is to use "id" for the primary key name instead of what you're doing.
Fix those problems - especially the first one - and your overall problem should go away.

Answer 4

Prepare query like this:
public function getAttendanceRecord($employeeId, $date) {
try {
$query = Doctrine_Query::create()
->from("attendanceRecord")
->where("employeeId = ?", $employeeId);
$records = $query->execute();
if (is_null($records[0]->getId())) {
return null;
} else {
return $records;
}
} catch (Exception $ex) {
throw new DaoException($ex->getMessage());
}
}
And try to get/print like this:
$attendanceOfTheDay = AttendanceDao::getAttendanceRecord($parameters['employeeId'], $parameters['date'])->toArray();
echo ' '; print_r($punchInTImeOfTheDay);
exit();
