Menu
Good morning, I have a form on a test AMP page (is AMP validate) and the form works: I receive the email with result (I use a php to handle it). I don't know (I did some try but I think I still missing an example) the syntax for let the AMP page responce correctly (now I get "Subscription failed!" but I do get the email) or redirect after submission. Here my example:
AMP page with form (I receive form result after submission but I don't know how to redirect or get "Subscription successful!" message)
Non AMP page with form (I receive form result and it redirect correctly)
action-xhr file destination code: Code of the php here in txt format (the file that handle the form result)
Any example will be great for me also only about redirect. Thank you

You can redirect user after successful submission, however it can only be done if you are submitting values to a secure URL (like https://www.example.com).

This post helped me create an AMP redirect response for C# thank you:
public virtual ActionResult AmpRedirect(string redirectUrl, string __amp_source_origin)
{
if (redirectUrl != string.Empty)
{
HttpContext.Response.AddHeader("AMP-Redirect-To", redirectUrl);
HttpContext.Response.AddHeader("AMP-Access-Control-Allow-Source-Origin", __amp_source_origin);
HttpContext.Response.AddHeader("Access-Control-Expose-Headers", "AMP-Redirect-To, AMP-Access-Control-Allow-Source-Origin");
}
HttpContext.Response.AddHeader("Content-type", "text/json");
return Json(new {Content = ""});
}
