How do I set a default value in an input field with CakePHP?
提问by Dave
I thought I could just use "value" like below, but it doesn't seem to work. Thanks in advance for any help.
我以为我可以像下面那样使用“价值”，但它似乎不起作用。在此先感谢您的帮助。
<?php
echo $this->Form->create('Email', array('url'=>'/emails/add', 'value'=>'enter your email address', 'inputDefaults'=>array('label'=>false)));
echo $this->Form->input('Email.email');
echo $this->Form->end('SIGN-UP');
?>
I tried setting in my controller (ty @Jared), but it doesn't seem to work. Thoughts on what I'm doing wrong?
我尝试在我的控制器（ty @Jared）中进行设置，但它似乎不起作用。想想我做错了什么？
<?php
class EmailsController extends AppController {
var $name = 'Emails';
function beforeFilter() {
parent::beforeFilter();
$this->Auth->allowedActions = array('add');
}
function create() {
$this->data['Email']['email'] = 'enter your email address';
}
}

You're setting the value in the wrong place. You want to set the default value of the input element like this:
您在错误的位置设置了值。您想像这样设置输入元素的默认值：
echo $form->input('email',array('default'=>'enter your email address'));
Look at this page in the manual.

Use a controller to set defaults. It prevents any issues that might happen and you get your default value returned, not the intended user input value:
使用控制器设置默认值。它可以防止可能发生的任何问题，并返回默认值，而不是预期的用户输入值：
class ProjectsController extends AppController
{
function create()
{
$this->data['Project']['name'] = 'Default Project Name';
}
}
