单击接受后显示警报消息和重定向 [英] Display alert message and redirect after click on accept

问题描述

好吧，我有一个页面，其中包含报告的链接。每当有人点击一个报表，他们可以下载excel文件。然而，有时没有字段来报告;在这种情况下，我想显示一个警报消息，他们单击接受后，他们被重定向到主面板。当他们点击报告时，他们去一个控制器，使用开关获取数据。如果没有数据，模型返回 FALSE ;所以在控制器的最后，我检查：

Well, I have a page with links to reports. Whenever somebody clicks on one report, they can download the excel file. However, sometimes there are no fields to make a report; in that case, I want to display an alert message and after they click on "accept", they get redirected to the main panel. When they click on the report, they go to a controller that uses a switch to get the data. If there's no data, the model returns FALSE; so at the end of the controller, I check:

if ($result_array != FALSE)
    to_excel($result_array->result_array(), $xls,$campos);
else {
    echo "<script>alert('There are no fields to generate a report');</script>";
    redirect('admin/ahm/panel');
}

如果我摆脱了 redirect ahm / panel'）; 然后警报工作，但它将用户移动到应该生成excel文件的页面。但是，如果我使用重定向，控制器会将用户移动到主面板，而不显示警报。

If I get rid of redirect('admin/ahm/panel'); then the alert works, but it moves the user to the page that was supposed to generate the excel file. But if I use the redirect, the controller moves the user to the main panel without showing the alert.

任何帮助都很感激。

提前感谢。

推荐答案

echo "<script>
alert('There are no fields to generate a report');
window.location.href='admin/ahm/panel';
</script>";

并除去下面的 redirect

你混淆了两个不同的世界。

You were mixing up two different worlds.
