ajax redirect to exception/error pages - kristianlake - 06-20-2020
Hi all,
When I use ajax and it returns an error, This is working great and as expected, but how do i let CodeIgniter deal with the returned error?
I looked in the manual and googled, but not sure what it is I am looking for!
error: function(xhr, status, error) {
if(xhr.status == 400) {
//redirect to 400 page!
}
How Do i pass this on so CodeIgniter shows its exception page(in dev)? (or any custom page in prod 400,500 etc)

Looks like you would need to do the error handling yourself.

Thanks Insite, I figured as much.
I guess I will deep dive into the code and see if i can figure it out

You will need to use Javascript to make a redirect.
Code:
error: function(xhr, status, error) {
if(xhr.status == 400) {
//redirect to 400 page!
window.location = "https://example.com/error400";

Spot on again Dave!.
I find that
var url= "http://localhost:8080/errors/html/error_404";
window.location = url;
is working great but
var url= "http://localhost:8080/errors/html/production";
window.location = url;
Does not return back the production "generic error" page.
Makes me wonder if my 404 is actually working or failing and redirecting me to a 404 anyway!
Any tips on this one?
RE: ajax redirect to exception/error pages - dave friend - 06-22-2020
Looking at the URLs you're setting for window.location I pretty sure you are getting redirecting to a 404 anyway.
CodeIgniter expects the URL segments after to represent controller/method/args and errors/html/error_404 does not fit that pattern.
So you will need to create a controller/method to handle the error condition (or conditions) that might be returned.
The methods should either load a view detailing the error or throw an exception - possibly both. From the controller/methods, you can
PHP Code:
echo view('errors/html/error_404');
or
PHP Code:
echo view('errors/html/production);
Or any other view files in errors/html or any custom pages saved anywhere you care to create them.
