CakePHP 2.0 $ this-> Form-> input（） [英] CakePHP 2.0 $this->Form->input()

问题描述

这是我的add.tcp
...

This is my 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：groups
表字段：group_id，group_desc
PK：group_id

Table name: groups Table fields: group_id, group_desc PK: group_id

这是我的控制器
...

This is my 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'));
      }
    }
  }  
}

我在浏览器上显示这个视图，没有字段group_id，但是有group_desc，HTML源代码看起来像这样
...

When I display this view on the browser, there was nothing for the field group_id but there was for the group_desc, the HTML source for the look like this ...

<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>

为什么被隐藏？

推荐答案

CakePHP自动确定您不希望用户手动输入ID，因此会为您隐藏ID。

CakePHP automagically determines that you do not want a user to manually enter an ID, as such hides it for you.

要强制显示ID字段，请将类型设置为文本：

If you would like to force ID field to be shown, set the type to text:

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