CakePHP 2.0 $this->Form->input()

Question

这是我的add.tcp...

<?php

echo $this->Form->create('Group');
echo $this->Form->input('group_id', array('label' => 'ID'));
echo $this->Form->input('group_desc', array('label' => 'Group Description'));
echo $this->Form->end('Save');

?>

表名:组表字段:group_id、group_descPK: group_id

这是我的 Controller ...

class GroupsController extends AppController {
  public $helper = array('Html', 'Form', 'Session');
  public $components = array('Session');

  public function add() {
    if ($this->request->is('post')) {
      if ($this->Group->save($this->request->data)) {
        $this->session.setFlash('');
        $this->redirect(array('action' => 'index'));
      }
    }
  }  
}

当我在浏览器上显示此 View 时，字段 group_id 没有任何内容，但有 group_desc，HTML 源看起来像这样...

<form action="/cakephp/index.php/groups/add" id="GroupAddForm" method="post" accept-charset="utf-8" name="GroupAddForm">
    <div style="display:none;">
        <input type="hidden" name="_method" value="POST">
    </div><input type="hidden" name="data[Group][group_id]" id="GroupGroupId">
    <div class="input text">
        <label for="GroupGroupDesc">Group Description</label><input name="data[Group][group_desc]" maxlength="15" type="text" id="GroupGroupDesc">
    </div>
    <div class="submit">
        <input type="submit" value="บันทึก">
    </div>
</form>

为什么要隐藏？

Answer 1

CakePHP 会自动确定您不希望用户手动输入 ID，因此会为您隐藏它。

如果您想强制显示 ID 字段，请将 type 设置为 text:

echo $this->Form->input('group_id', array('type' => 'text', 'label' => 'ID'));
