我是cakephp的新手，我需要验证表格。
这是代码： 控制器：
<?php
class TasksController extends AppController {
var $name = 'Tasks';
var $helpers = array('Html','Form','Session');
public function index(){
}
function add_task()
{
if(!empty($this->data)) {
//print_r($this->data);
$this->Task->set($this->data);
if ($this->Task->validates()) {
// it validated logic
//echo "ttt";
} else {
// didn't validate logic
echo $errors = $this->Task->validationErrors;
}
}
}
}
?>
型号：
<?php
class Task extends AppModel
{
public var $name = 'Task';
var $useDbConfig = 'travanco_erp';
public var $useTable = 'tbl_tasks'; // This model uses a database table 'exmp'
public var $validate = array(
'task_title_mm' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'The title field is required'
),
'task_description_mm' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'The description field is required'
),
'task_from_mm' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'The from date field is required'
),
'task_to_mm' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'The to date field is required'
)
);
}
?>
这是观点：
<div class="employeeForm" style="width:64%; padding:10px 30%;">
<?php echo $this->Form->create('test', array('class'=>'form'));?>
<fieldset style="width:36em; padding:0px 0px;">
<div style="width:475px; font-family:Arial, Helvetica, sans-serif; font-size:16px; color:#333333; font-weight:bold; margin-left:20px; margin-top:10px;">Add Task</div>
<br/>
<?php
/*echo $this->Form->input('task_ids_mm', array( 'div'=>'frm_filed_new',
'error' => array( 'wrap' => 'div',
'class' => 'formerror'
),
'label' => 'Task ID',
));*/
echo $this->Form->input('task_title_mm', array( 'div'=>'frm_filed_new',
'error' => array( 'wrap' => 'div',
'class' => 'formerror'
),
'label' => 'Title',
));
echo $this->Form->input('task_description_mm', array( 'type' => 'textarea',
'cols'=>60,
'rows' => 5,
'div'=>'frm_filed_new',
'error' => array( 'wrap' => 'div',
'class' => 'formerror'
),
'label' => 'Description',
));
echo $this->Form->input('task_from_mm', array( 'div'=>'frm_filed_new','id'=>'task_from_mm','value'=>'',
'error' => array( 'wrap' => 'div',
'class' => 'formerror'
),
'label' => 'From',
));
echo $this->Form->input('task_to_mm', array( 'div'=>'frm_filed_new','id'=>'task_to_mm','value'=>'',
'error' => array( 'wrap' => 'div',
'class' => 'formerror'
),
'label' => 'To',
));
?>
<br/>
<?php echo $this->Form->button('Submit', array('type'=>'submit','escape'=>true)); ?>
</fieldset>
<?php echo $this->Form->end(); ?>
</div>
验证无效。
我的代码中有什么错误？ 我该如何解决这个问题？
编辑：
这是databse.php文件配置错误的错误。现在它已经更正了。print_r($errors)显示错误。但是没有显示在视图页面中，我的意思是在文本框附近。
这是错误数组：
Array ( [task_title_mm] => Array ( [0] => The title field is required ) [task_description_mm] => Array ( [0] => The description field is required ) [task_from_mm] => Array ( [0] => The from date field is required ) [task_to_mm] => Array ( [0] => The to date field is required ) )
如何将它放在文本框附近？

CakePHP旨在自动验证模型并显示验证错误。自动验证在模型保存上运行。在你的情况下：
$this->Task->save($this->request->data);
将触发验证。无需运行：$ this-＆gt;任务 - ＆gt; validates（） - 如果这样做，您还必须自己负责显示验证错误。所以我认为你应该尝试：
<?php
class TasksController extends AppController {
var $name = 'Tasks';
var $helpers = array('Html','Form','Session');
function add_task()
{
if ($this->request->is('post')) {
// If the form data can be validated and saved...
if ($this->Task->save($this->request->data)) {
//saved and validated
}
}
}
}
?>

我在你的代码中注意到你在模型中写的一件事
public var $validate=array();
而不是尝试
public $validate= array() or var $validate=array();
验证应该在单词之后起作用。 谢谢:)）

试试这个：
if ($this->Task->validates()) {
// it validated logic
//echo "ttt";
} else {
$this->validateErrors($this->Task);
$this->render();
}
