大家好,我遇到了这个问题,当我单击提交时,表单没有更新。它进入 if($this->request->is("post")){....} 块,但它没有更新。
这是代码。
页面控制器.php
public function admin_edit($id=NULL){
$this->request->data = $this->Page->find("first",array("conditions"=>array("Page.id"=>$id)));
if($this->request->is('post')){
$this->request->data["Page"]["id"] = $id;
if($this->Page->save($this->data)){
echo "Done";
}
}
}
admin_edit.php
URL -> http://localhost/cakephp_practice/admin/pages/edit/4
<table width="100%" border="0" cellspacing="0" cellpadding="0" class="DataTable">
<tr>
<th>Administrator > Edit Page</th>
</tr>
<tr>
<td>
<?php
echo $this->Form->create('Page', array("action" => "edit", "method" => "Post",'enctype' => 'multipart/form-data', 'id' => 'editPage'));
?>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td colspan="2"> <span class="require">* Please note that all fields that have an asterisk (*) are required. </span></td>
</tr>
<tr>
<td>Name: <font color="red">*</font></td>
<td align="left"><?php echo $this->Form->text('Page.name', array('maxlength' => '254', 'size' => '20', 'label' => '', 'div' => false, 'class' => "form-inbox required")) ?>
</td>
</tr>
</table>
<table>
<tr>
<td> </td>
<td>
<?php echo $this->Form->submit('Submit', array('maxlength' => '50', 'size' => '30', 'label' => '', 'div' => false)) ?>
</td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>
<?php echo $this->Form->end(); ?>
</td>
</tr>
</table>
我用过 Configure::write('Routing.prefixes', 'admin'); 自动将 localhost://project_name/admin/pages/edit 等 url 解析为 pages 控制器的 admin_edit 操作。
编辑:当我 print_r($this->request->data); 在 if 块中,名称字段仍然包含旧值而不是我输入的新值。这是为什么?
这一行:-
if($this->Page->save($this->data)){
应该:-
if($this->Page->save($this->request->data)){
但是,您的方法的第一行是覆盖$this->request->data
它应该包含您的表单数据!
