在 ZF2 中向 mysql table 添加数据

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>

问题是totalMarks和subjectMarkDesc添加正确，而subjectName取了主题[的id[0] =29=]，对于输入的任何名称。

Answer 1

答案很简单，我们可以看到subjectName作为输入被插入而subjectId被隐藏，所以没有直接关系即, 阐明哪个 subjectName 分配给 subjectId.

所以放一个 select HTML 标签就可以解决问题，例如

<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.
