I'm trying to register a custom route to validate a groupon voucher code for a landing page. I registered the route in functions.php like so:
// Adding Custom Voucher Route
add_action('rest_api_init','register_voucher_endpoint');
function register_voucher_endpoint() {
register_rest_route(
'voucher',
'verify/(?<voucher_code>)',
array(
'methods'=> 'POST',
'callback'=>'verify_voucher'
));
}
function verify_voucher($request) {
return $request['voucher_code'];
}
I set the link on the form action like this
<form action="/voucher/verify" method="POST">
<h5 class="title">Please enter your 8-character Groupon Voucher Code to redeem your
purchase</h5>
<p>Note: You will have a voucher code for each product you buy on Groupon. For example,
if you bought 2 CBD sprays on Groupon, you'll have to enter 2 voucher codes, one
for each spray.</p>
<input required="" class="branded-input margin-bottom" type="text"
minlength="8" maxlength="8" title="voucher-code" name="voucher-code" placeholder="Enter your 8 Character Groupon code">
<input type="submit" value="Redeem My CBD!" class="btn btn-color-primary btn-style-bordered btn-size-large">
When I click the submit button or go to the registered route manually, it redirects to the home page and the network tab shows that the 'verify' route returned a 301. The site is using redirection but none of the options include the custom route I registered.
Two main questions:
- Why is this redirect happening?
- How do I capture the code entered into the input field in the callback function?
Thanks in advance for your answer.

Reset to default 0Just a guess: Your regular expression 'verify/(?<voucher_code>)' is not correct. Have a look here. They are using e.g. (?P[a-zA-Z0-9-]+) there's a P inside.
Another reason could be that you are missing a / before the verify. Try this:
function register_voucher_endpoint() {
register_rest_route(
'voucher',
'/verify/(?P<voucher_code>[a-zA-Z0-9-]+)',
array(
'methods'=> 'POST',
'callback'=>'verify_voucher'
));
}
[a-zA-Z0-9-] defines the regular expression group for this endpoint.
To answer question nr. 2: check the global $_POST array. There you should have an voucher-code entry which you can access with $_POST['voucher-code'].
I'm not 100% sure my answer is correct.
