What's wrong with this PHP CURL script (integrating Foursquare API)? - php

Question

I am trying to integrate Foursquare API to my website, here is the code:
$curl = curl_init('https://api.foursquare.com/v2/photos/add?v=20181008&oauth_token='.$token.'&photo='.$args['img'].'&venueId='.$title);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
// Decode the response
$data = json_decode($data);
// Verify if the post was published
if ( #$data->meta->code == 200) {
return true;
} else {
return false;
}
But when I run this script on my website and try to post image, it is showing
An error occurred while processing your request

Answer 1

Remove the lines
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
and try a simple
curl_setopt($curl, CURLOPT_POST, false);
You are sending the Request with GET Arguments

Answer 2

This could have multiple reasons.
I can't tell from the error message where exactly it triggers but when the curl fails, you should first investigate if there were any issues with the curl request itself.
Use curl_error for this: http://php.net/manual/de/function.curl-error.php
And are you using the API-Call the correct way?
In the docs POST https://api.foursquare.com/v2/photos/add
theres no $photo param at all.
Also when using POST you should add the parameters via
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
and not as GET-Parameters via URL.
