arrays - 将数组保存到数据库cakephp

Question

我有一个表单在同一个表中有多个条目，我遇到的问题是它只将最后一个条目发送到数据库而不会发送其余条目。我使用了调试，它只打印出表单中的最后一个字段。

field 的每次迭代都意味着将 fields_invoices 表输入 invoice_id, field_id, entered_value

这是我的表格

<?php echo $this->Form->create('FieldsInvoice'); ?>
    <?php foreach ($fields as $field): ?>
    <?php echo $this->Form->hidden('FieldsInvoice.id'); ?>
    <?php echo $this->Form->hidden('FieldsInvoice.field_id', array('default' =>$field['Field']['id'])); ?>
    <?php echo $this->Form->input('FieldsInvoice.invoice_id', array('default' =>$invoice_id, 'type'=>'hidden')); ?>
    <?php echo $this->Form->Input('FieldsInvoice.entered_value',  array('label'=>$field['Field']['name'], 'default' =>$field['Field']['default_value'])); ?>
    <?php endforeach ;?>
    <?php echo $this->Form->End('Submit');?>

这里是相关的 Controller

    public function create($id)
    {   
    $this->set('title_for_layout', 'Create Invoice');
    $this->set('stylesheet_used', 'homestyle');
    $this->set('image_used', 'eBOXLogoHome.png');   
    $this->layout='home_layout';


     if (!is_numeric($id)) throw new BadMethodCallException('I need an ID');
     $this->Invoice->id = $id;
     if (!$this->Invoice->exists()) throw new NotFoundException('Invalid ID');

    $this->set('invoice_id',$id);

    $names = $this->Invoice->find('list',array(
    'fields'=>array('template_id'),
    'conditions'=>array('id'=>$id)));

    $fields = $this->Field->find('all', array(
      'conditions'=>array(
     'template_id'=>$names)));

    $this->set(compact('fields'));
    $this->set(compact('invoice_id'));

    $this->set('name',$names);
    $this->Invoice->create();
    if(empty($this->data)){
        $this->data= $this->Field->read($id);
    } 
    else{
        if($this->request->is('post'))
        {
            //die(debug($this->data));

            $this->Invoice->create();
            if($this->FieldsInvoice->save($this->request->data, array('deep'=>true)));
            {
            $this->Session->setFlash('The field has been updated');
            $this->redirect(array('controller'=>'invoices', 'action'=>'index'));

            }
            //else{
            $this->Session->setFlash('Could not be saved');
            //}
        }
    }
}

Answer 1

要发布多个字段，请使用:

foreach ($fields as $idx => $field):
    echo $this->Form->hidden('FieldsInvoice.'.$idx.'.id');   
    echo $this->Form->hidden('FieldsInvoice.'.$idx.'.field_id', ...);
    ...

然后使用$this->FieldsInvoice->saveMany()(而不是->save())保存多条记录。
