cakephp render-false动作仍然回显html模板 [英] cakephp render-false action still echoes html template
问题描述
对于我的控制器中不需要视图的操作，我将禁用布局和模板，如下所示：
$ this-> autoRender = false;
这一切都很好。然而，在同一个动作中，我回应一个通过或失败来表示我的看法的结果。问题是一堆文本也回声：（我的失败或通过在最后）

这是回应8 o 9次。
如何摆脱这样的只有我的通过或失败回声？
您能帮助吗？
我尝试过
$ this-> layout = false;和
$ this-> render（false）;非常感谢你。
em> 更新：**
只是注意到它也回荡了一堆javascrip代码，无处可见（删除< for pasting here）eg：pre class =cake -errora href =javascript：void（0）; onclick =document.getElementById（'cakeErr5035af14add0c-trace'）。style.display =（document.getElemen ..

解决方案我将在这里粘贴一个来自cakeapi的片段，位于 http://api.cakephp.org/class/controller 关于autoRender如何工作：
autoRender boolean
设置为true以自动呈现视图之后
因此：
$ this-> autoRender =假的
通常会关闭呈现视图，但只是在动作逻辑完成后。所以这就是为什么你从你的行动逻辑得到回报。您可以选择是否从代码中删除回声，以防止显示它们或尝试此模式。
如果出现错误：
$ this-> Session-> setFlash（'Error'）;
$ this-> redirect（array（'action'=>'your_error_page'））;
这将移动到ur错误页面，错误字符串作为Flash文本， ：
$ this-> Session-> setFlash（'Its fine dude！'）;
$ this-> redirect（array（'action'=>'your_ok_page'））;
For an action in my controller that needs no view, I'm disabling the layout and template like this:
$this->autoRender = false;
And it's all good. However, in that same action I'm echoing a 'pass' or 'fail' to signal my view of the result. The problem is a bunch of text is also echoed: (my 'fail' or 'pass' at the very end)

This is echoed 8 o 9 times.
How can I get rid of that so only my 'pass' or 'fail' are echoed?
Can you help?
I've tried
$this->layout = false; and
$this->render(false);
Thank you so much.
Update:**
Just noted it also echoes a bunch of javascrip code out of nowhere, (Removed < for pasting here) e.g.: pre class="cake-error" a href="javascript:void(0);" onclick="document.getElementById('cakeErr5035af14add0c-trace').style.display = (document.getElemen..

$this->autoRender = false;

'recursive' => 0,

解决方案 First of all I will paste here a fragment from cakeapi under http://api.cakephp.org/class/controller about how autoRender works:
autoRender boolean
Set to true to automatically render the view after action logic.
So this:
$this->autoRender = false ;
will generally turns off rendering the view but just after action logic is done. So thats why you get the echos from your action logic. You can whether remove your echo's from your code to prevent showing them or try this schema,
if something is wrong:
$this->Session->setFlash('Error');
$this->redirect(array('action' => 'your_error_page'));
which will move you to ur error page with Error string as a Flash text, or when its all fine:
$this->Session->setFlash('Its fine dude!');
$this->redirect(array('action' => 'your_ok_page'));
