提交按钮重定向多个页面

Question

Is there possible to redict multiple page after submit button? For example, user click 'Submit' then it will go to page1.php (same tab) and page2.php (another tab).

<form role="form" method="post" action="">
<button type="submit" name="submit" >Submit</button>
</form>

if(isset($_POST['submit'])){
header("location:page1.php");
header("location:page2.php");
}

Answer 1

The simple answer is no. Only the page that submitted the request can receive a redirect response. The more complicated answer is if the first page opened the second page it can exercise some control over it via javascript. You could also use a websocket based mechanism to cause a page to reload similar to how react dev server works.

Answer 2

You can use a combination of php and javascript.

Add a javascript function to the onsubmit of the form:

var win = window.open(url, '_blank');

then, in your php, use your code to check for $_POST var and use:

header('Location: url');
