如何在 prestashop 1.7.7.7 的管理面板上显示自定义通知或错误消息？

嗨，＆nbsp;

我一直在尝试很多选择来管理异常，并在管理面板上显示错误，但似乎没有工作。

我正在使用自定义模块的后进程方法。用户通过表单发送CSV文件并检查数据后（这里一切正常），如果发生异常，我需要显示一条消息，停止并重定向到同一页面。＆nbsp;

我已经尝试过：＆nbsp;

this->get('session')->getFlashBag()->add('error',$msg);
Tools::redirectAdmin('index.php?controller='.$controller.'&token='.$token);

这个：＆nbsp;

header("HTTP/1.0 400 Bad Request");
die(json_encode(array( 'error' => array($this->l(' Error') ))));

（一个人可以使用，但显示了一个带有消息的空白页，而不是管理面板内的消息）＆nbsp;

也是这样：＆nbsp;

$this->context->smarty->assign(array(
    'token' => Tools::getAdminTokenLite('AdminModules'),
    'errors' => $this->errors
));
$this->setTemplate('ExcelProcess.tpl');

和{$ errors | var_dump}在tpl显示null ...

和许多其他选项。＆nbsp;

我找不到关于PS文档的退回式自定义通知的任何内容，只有关于前面的自定义通知。

有任何线索吗？＆nbsp;

＆nbsp;

非常感谢！＆nbsp;

Hi,

I've been trying a lot of options to manage an exception and show an error at admin panel but nothing seems to work.

I'm at the postProcess method of a custom module. After the user sends a csv file through a form and the data is checked (everything works fine here), if an exception occurs I need to show a message, stop and redirect to the same page.

I've tried this:

this->get('session')->getFlashBag()->add('error',$msg);
Tools::redirectAdmin('index.php?controller='.$controller.'&token='.$token);

this:

header("HTTP/1.0 400 Bad Request");
die(json_encode(array( 'error' => array($this->l(' Error') ))));

(that one works but shows a blank page with the message, not the message inside the admin panel)

also this:

$this->context->smarty->assign(array(
    'token' => Tools::getAdminTokenLite('AdminModules'),
    'errors' => $this->errors
));
$this->setTemplate('ExcelProcess.tpl');

and {$errors|var_dump} at the tpl displays null...

... and many other options.

I can't find anything either about backoffice custom notifications at the PS docs, only about front custom notifications.

Any clue?

Thanks a lot!

Miguel

添加 postprocess（）中的错误

$this->errors[] = $this->l('My error');

可以通过设置或

$this->context->controller->errors[] = $this->l('My error');

在表单提交检查中。
您的错误消息将渲染到红色框中。

如果要显示警报而不重新加载页面，则必须对AdminController执行Ajax调用，恢复JSON响应并呈现错误消息，导致呼叫的执行。

参见

Adding an error in postProcess() can be achieved by setting

$this->errors[] = $this->l('My error');

$this->context->controller->errors[] = $this->l('My error');

during your form submission checks.
Form will be rendered with your error messages into a red box.

If you want to show an alert without reloading the page instead, you'll have to perform an AJAX call to your AdminController, get back a JSON response and render your error message as a result of the execution of the call.
