Question

嘿大家我遇到这个问题，当我点击提交时表单没有更新。如果（$ this-＆gt; request-＆gt;是（＆＃34; post＆＃34;））{....}阻止但是它没有更新。

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>

我使用过Configure :: write（＆＃39; Routing.prefixes＆＃39;，＆＃39; admin＆＃39;）;自动解析url，如localhost：// project_name / admin / pages / edit to admin_edit pages controller of action。

编辑：当我print_r（$ this-＆gt; request-＆gt; data）时;在if块中，name字段仍然包含旧值而不是我输入的新值。那是为什么？

这一行： -

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

应该是： -

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

但是，您的方法的第一行是覆盖$this->request->data，其中应包含您的表单数据！

表格没有更新cakephp代码中的数据库表？
