Adding data to mysql table in ZF2 - php

Question

This is the code for add action, This action adds subjectName(from subjects Table), totalMarks and Description (from SubjectMarks Table)
public function addAction() {
$postArray = $this->params()->fromPost();
$entityManager = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
This if condition is set true if data is entered and addbutton is clicked
if (isset($postArray['submit']) && $postArray['subjectName']) {
$subjectMarks = new SubjectMarks();
$subjectMarks->setSubject(
$entityManager->find('Application\Entity\Subjects', $postArray['subjectName'])
);
$subjectMarks->setClasses(
$entityManager->find('Application\Entity\Classes', $postArray['classId'])
);
$subjectMarks->setSubject(
$entityManager->find('Application\Entity\Subjects', $postArray['subjectId'])
);
$subjectMarks->setTotalMarks($postArray['totalMarks']);
$subjectMarks->setDescription($postArray['subjectMarksDesc']);
$entityManager->persist($subjectMarks);
$entityManager->flush();
return $this->redirect()->toUrl($this->getRequest()->getBaseUrl().'/subjectmarks/totalmarks/index');
}
First else is executed that runs the query and sends data to 'add' view in form of 'data'
else
{
$entityManager = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
$qb = $entityManager->createQueryBuilder();
$qb->select(array(
'subjectMarks.subjectMarkId as subjectMarkId',
'subjectMarks.totalMarks as totalMarks',
'subjectMarks.description as subjectMarksDesc',
'subject.subjectId as subjectId',
'subject.name as subjectName',
'class.classId as classId',
))
->from('Application\Entity\SubjectMarks', 'subjectMarks')
->leftJoin('subjectMarks.subject', 'subject')
->leftJoin('subjectMarks.classes', 'class');
$data = $qb->getQuery()->getScalarResult();
return new ViewModel(array(
'data' => $data,
)
);
}
}
This is the code for add.phtml 'FORM' which is called when 'else' part executes and query selects the data required, and send the written data back, where it is received by if() condition.
<form name="myForm" action="<?php echo $this->url('subjectmarks/totalmarks', array('action'=>'add'));?>" method="POST">
<input type="hidden" name="classId" value="<?php echo $this->data[0]['classId'];?>">
<input type="hidden" name="subjectId" value="<?php echo $this->data[0]['subjectId'];?>">
<input type="text" name="subjectName" >
<input type="text" name="totalMarks" >
<input required="required" type="text" name="subjectMarksDesc" >
<button type="reset" class="btn btn-primary" > <a style="color: white" href="<?php echo $this->basePath('subjectmarks/totalmarks/index');?>">Cancel</a></button>
<button type="submit" name="submit" class="btn btn-success">Submit</button>
The Problem is that totalMarks and subjectMarkDesc are added correctly, while the subjectName is taken id[0] of subject table, for any name that is entered.

Answer 1

The answer is simple, as we can see that subjectName is inserted as input and subjectId is hidden, so there is no direct relation i.e, that clarify which subjectName is assigned to the subjectId.
So putting a select HTML tag will solve the problem, e.g
<select name="addSubjectMarks">
<?php foreach ($this->data as $item):?>
Here we can see subjectId and subjectName are related, unlike the question
<option value="<?php echo $item['subjectId'];?> "> <?php echo $item['subjectName'];?> </option>
<?php endforeach; ?>
</select>
Similarly there in the controller, inside the if (isset($postArray['submit']) && $postArray['subjectName']) condition, we will only replace this code
$subjectMarks->setSubject(
$entityManager->find('Application\Entity\Subjects', $postArray['addSubjectMarks'])
);
with this code
$subjectMarks->setSubject(
$entityManager->find('Application\Entity\Subjects', $postArray['subjectName'])
);
$subjectMarks->setSubject(
$entityManager->find('Application\Entity\Subjects', $postArray['subjectId'])
);
and it will perfectly. The select tag will output only those subjectNames which are already present in the subject Table.
