我有问题在一个表中保存多个记录。这是我的表格:Cakephp在一个模型中保存多个记录
<?php echo $this->Form->create('Attendance');?>
<table>
<tr>
<th>Student</th>
<th>Attendance</th>
</tr>
<?php foreach ($students as $key => $student): ?>
<tr>
<td>
<?php echo $student['LectureParticipant']['name']; ?>
<?php echo $this->Form->input('Attendance.'.$key.'.student_id', array('type'=>'hidden', 'value'=>$student['LectureParticipant']['student_id'])); ?>
<?php echo $this->Form->input('Attendance.'.$key.'.lecture_id', array('type'=>'hidden', 'value'=>$student['LectureParticipant']['lecture_id'])); ?>
<?php echo $this->Form->input('Attendance.'.$key.'.date', array('type'=>'hidden', 'value'=>date("Y-m-d"))); ?>
</td>
<td>
<?php
echo $this->Form->input('Attendance.'.$key.'.participant', array(
'label' => false,
'div' => false,
'type' => 'select',
'options' => array(
'1' => 'Present',
'0' => 'Absent',
),
));
?>
</td>
</tr>
<?php endforeach; ?>
</table>
<center>
<?php echo $this->Form->submit('Save', array('class'=>'greenBtn', 'div'=>false));?>
<?php echo $this->Html->link("Cancel", array('action' => 'viewTeacherClass'), array('class' => 'button redBtn')); ?>
<?php echo $this->Form->end();?>
</center>
,这是我的控制器:
if ($this->request->is('post')) {
if ($this->Attendance->saveAll($this->request->data)) {
$this->Session->setFlash('Attendance has been saved.');
$this->redirect(array('controller'=>'programmes', 'action' => 'viewTeacherClass'));
} else {
$this->Session->setFlash('Unable to add attendance.');
}
}
这是我的数据结构:
array(
'Attendance' => array(
(int) 0 => array(
'student_id' => '1',
'lecture_id' => '2',
'date' => '2013-08-02',
'participant' => '1'
),
(int) 1 => array(
'student_id' => '2',
'lecture_id' => '2',
'date' => '2013-08-02',
'participant' => '1'
)
)
)
我得到了这样的警告:
Warning (2): array_keys() expects parameter 1 to be array, null given [CORE\Cake\Model\Model.php, line 2045]
Warning (4096): Argument 1 passed to Hash::numeric() must be an array, null given, called in C:\wamp\www\ibae\lib\Cake\Model\Model.php on line 2045 and defined [CORE\Cake\Utility\Hash.php, l
我不确定这里出了什么问题。我猜是因为这个警告,我无法保存所有的数据。
看看2045行['Model.php']中的代码(https://github.com/cakephp/cakephp/blob/a643295e4c48681d26d775d6f50a395e194eaf04/lib/Cake/Model/Model.php#L2045),' $ data'参数直接传递给'array_keys()',所以'$ this-> request-> data'似乎是'null'。 – ndm
我已经调试过($ this-> request-> data)并且它不为空 – Najmi
好吧,如果确实如此,并且您发布的代码实际上是触发错误的代码,那么请检查在你的特定的CakePHP版本中你应该总是提到确切的版本号,在Model Model的saveAll()之前做一些调试(例如'var_dump($ data)') '在控制器中,在'Model :: saveAll()'方法内部检查方法实际接收的方法),如果这不能让你在轨道上解决问题,那么请用你的调试更新你的答案结果。 – ndm
