How to reload page after post

- 1 answer

I'm currently creating a form on a page in OctoberCMS that executes a PHP code block.

HTML/Twig:

{{ form_open({ request: 'onHandleForm' }) }}
    Please enter a string: <input type="text" name="value"/>
    <input type="submit" name='submitform' value="Submit me!"/>
{{ form_close() }}
<p>Last submitted value: {{ lastValue }}</p>

PHP:

function onHandleForm()
{
    $this['lastValue'] = post('value');
}

As you can see this is very simple, PHP creates a twig tag with a value equal to the user input which is then output in the HTML.

However, every time I try to reload the page after posting something I get the error:

The page that you're looking for used information that you entered. Returning to that page might cause any action you took to be repeated. Do you want to continue?`

I've tried every method I can find but I can't get that error to stop coming up. I know it has something to do with the server trying to repost the same data when you reload the page but I can't for the life of me figure out how to fix it, I've tried every single method of reloading the page using PHP that I can find and none of them seem to work.

Please don't close this as a duplicate, if any of the existing posts helped me I wouldn't be making a new one.

Update: I'm not sure but it seems like reloading the page is not getting rid of the error: I just added onsubmit="window.location.reload()" to my form and now when I submit it reloads the page but the error persists.

You can refresh the page from the ajax handler inside controller if you return this:

return redirect()->refresh();
