I am having issues with wp_remote_get
in my Wordpress plugin.
What I want to do is call a method inside my main public class with ajax. But the thing is that the call fails when the wp_remote_get
function is used in it. It is supposed to do an API call and return the data to the jQuery. When I comment out the wp_remote_get
the call works fine and response is given back. Any ideas how can I make this work?
Method that processes the call:
public function countryLookupApiCall() {
if (isset($_POST['action']) && isset($_POST['country'])) {
$country = $_POST['country'];
$apiKey = $this->getApiKey();
$url = $this->url . $country . '/callCharges?apiKey=' . $apiKey . '&response=JSON';
$response = wp_remote_get($url);
echo $response;
die();
}
}
jQuery:
jQuery(document).ready(function() {
jQuery("#countryLookupForm").submit(function(e){
var country = jQuery("#selectCountry").val();
var action = 'countryLookupResponse';
jQuery.ajax ({
type: 'POST',
url: countryLookup.ajaxurl,
dataType: 'json',
data: {action: action, country: country},
success: function(data) {
//do something with this data later on
var result = jQuery.parseJSON(data);
}
});
});
});
Wordpress actions are all registered well because the call works when I don't use the wp_remote_get
EDIT:
The solution was more than simple, I just needed to add e.preventDefault();
You need to add errors checking into your code. This can help you to figure out what is causing the problem.
public function countryLookupApiCall() {
if (isset($_POST['action']) && isset($_POST['country'])) {
$country = $_POST['country'];
$apiKey = $this->getApiKey();
$url = $this->url . $country . '/callCharges?apiKey=' . $apiKey . '&response=JSON';
$response = wp_remote_get($url);
if (is_wp_error($response)) {
$error_code = $response->get_error_code();
$error_message = $response->get_error_message();
$error_data = $response->get_error_data($error_code);
// Process the error here....
}
echo $response;
die();
}
}
Also you are using echo on wp_remote_get result. As defined in documentation wp_remote_get returs WP_Error or array instance. So you should use something like this:
echo $response['body'];
