表格未更新cakephp代码中的数据库表?

[英]Form not updating database table in cakephp code?

大家好,我遇到此问题时,单击“提交”时表格未更新。 它进入if($ this-> request-> is(“ post”)){....}块中,但未更新。

这是代码。

PagesController.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 &gt; 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>&nbsp;</td>
                        <td> 
                            <?php echo $this->Form->submit('Submit', array('maxlength' => '50', 'size' => '30', 'label' => '', 'div' => false)) ?>
                        </td>
                    </tr>
                    <tr>
                        <td>&nbsp;</td>
                        <td>&nbsp;</td>
                    </tr>
                </table>
                <?php echo $this->Form->end(); ?>
            </td>
        </tr>                      
    </table>

我已经使用过Configure :: write('Routing.prefixes','admin'); 自动将url(例如localhost:// project_name / admin / pages / edit)解析为页面控制器的admin_edit操作。

编辑:当我print_r($ this-> request-> data); 在if块中,名称字段仍包含旧值,而不是我输入的新值。 这是为什么?

这行:

if($this->Page->save($this->data)){

应该:-

if($this->Page->save($this->request->data)){

但是,方法的第一行将覆盖$this->request->data ,其中应包含表单数据!
