Question

我在数据库中有两列，id和表名下的列。我的编辑功能：

public function edit($id = null){
    if($this->Category->exists($id)){
        throw new NotFoundException (__('Id was not found '));
    }
    if($this->Auth->user('role')=='admin'){
    if(!$id){
        throw new NotFoundException(__('Id was not set'));
    }

    $data=$this->Category->findById($id);
    if(!$data){
        throw new NotFoundException(__('Id was not found in database'));
    }

   if($this->request->is(array('post','put')) ){

        if($this->Category->save($this->request->data)){
            $this->Session->setFlash('The data has been edited successfully');
            return $this->redirect(array('action' => 'index'));
            //$this->redirect('index');
        }

        else{
            $this->Session->setFlash("The data could not be edited");
            $this->redirect(array('controller'=>'categories','action'=>'index'));
        }
    }
//        else{
//            $options = array('conditions' => array('Category.' . 
 $this->Category->primaryKey => $id));
//          $this->request->data = $this->Category->find('first', $options);
//        }
    $this->request->data=$data;
}
else{
    $this->Session->setFlash(__('You do not have right to do this'));
    $this->redirect('index');
}
   }

我的分类/ edit.ctp

 <?php echo $this->Form->create('Category'); ?>
<fieldset>
    <legend><?php echo __('Edit Category'); ?></legend>
<?php
    echo $this->Form->input('id');      
    echo $this->Form->input('name');        
            echo $this->Form->input('id',array('type'=>'hidden'));
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>

每当我尝试编辑和更新表单时， $ this-＆gt; Session-＆gt; setFlash（“数据无法编辑”）;被执行。

Answer 1

Try: $this->Category->id = $this->request->data['id'];    if($this->Category->save($this->request->data)){
           $this->Session->setFlash('The data has been edited successfully');
           return $this->redirect(array('action' => 'index'));
           //$this->redirect('index');
       }

Answer 2

将$id传递给视图 -

$this->set(compact('id'));

然后将其设置为字段 -

echo $this->Form->input('id',array('type'=>'hidden', 'value' => $id));

如果您有隐藏的ID字段，那么为什么要显示另一个？如果不需要删除，否则正确分配值。希望它能奏效。

Cakephp编辑功能无效（$ this-＆gt; Category-＆gt; save（$ this-＆gt; request-＆gt; data））
