cakephp render-false 操作仍然回显 html 模板

对于 Controller 中不需要 View 的操作，我将禁用布局和模板，如下所示:

$this->autoRender = false;

一切都很好。然而，在同一操作中，我会回显“通过”或“失败”来表明我对结果的看法。问题是一堆文本也被回显:(我的“失败”或“通过”在最后)

 <!--

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
        </body>
</html>
<!--

and open the template in the editor.
-->
<!DOCTYPE html>
<html>
    <head> ....

这被重复了 8 到 9 次。

我怎样才能摆脱这个问题，以便只回显我的“通过”或“失败”？你能帮忙吗？

我已经尝试过

$this->layout = false; and
$this->render(false);

非常感谢。

更新:**刚刚注意到它还无缘无故地回响了一堆 javascrip 代码(删除了 < 以粘贴到此处)例如: pre class="cake-error"a href="javascript:void(0);"onclick="document.getElementById('cakeErr5035af14add0c-trace').style.display = (document.getElemen..

    if ($fileHandle) {

        // file was just no good
        echo 'fail';
        exit;
    }
    if (count($prodata) > 0) {
        $this->Qca->saveMany($prodata);
        echo count($prodata);
    }
}

最佳答案

首先，我将在 http://api.cakephp.org/class/controller 下粘贴来自 cakeapi 的片段。关于 autoRender 的工作原理:

自动渲染 bool 值
设置为 true 可以在操作逻辑之后自动渲染 View 。

所以这个:

 $this->autoRender = false ;

通常会在操作逻辑完成后关闭渲染 View 。这就是为什么你会从你的行动逻辑中得到回应。您可以从代码中删除回显以防止显示它们，也可以尝试此架构，

如果出现问题:

$this->Session->setFlash('Error');
$this->redirect(array('action' => 'your_error_page'));

这会将您移至错误页面，其中错误字符串为 Flash 文本，或者当一切正常时:

$this->Session->setFlash('Its fine dude!');
$this->redirect(array('action' => 'your_ok_page'));

关于cakephp render-false 操作仍然回显 html 模板，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12062097/
