$fb->fileToUpload($imageName) not working properly - php

Question

I am trying to upload the photo to user's profile through my code. Below is the code I am using:
echo $imageName;
$data = [
'message' => 'Visit http://www.mywebsite.com',
'source' => $fb->fileToUpload($imageName),
];
echo 'hi1';
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->post('/me/photos', $data, $accessToken);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
echo 'hi';
In above code echo $imageName is printing the required image name (variable contains desired value say images/abc.jpg) but when use the following it is not working:
$fb->fileToUpload($imageName)
If I remove variable name and give direct value like so it is working fine:
$fb->fileToUpload("images/abc.jpg") .
Can you please help me with whats wrong with my code.

Answer 1

Provide full path of image(http://example.com/image/1.jpg)
Try below one.
This is tested in version 5
require_once __DIR__ . '/src/Facebook/autoload.php';
$app_ID = 'xxxxxxxxx';
$APP_SECRET = 'xxxxxxxxxx';
$access_token = 'xxxxxxxxxx';
$fb = new Facebook\Facebook([
'app_id' => $app_ID,
'app_secret' => $APP_SECRET,
'default_graph_version' => 'v2.5',
]);
$data = [
'message' => 'My photo upload example.',
'source' => $fb->fileToUpload('http://example.com/images/1.jpg'),
];
try {
$response = $fb->post('/me/photos', $data, $access_token);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
echo 'Photo ID: ' . $graphNode['id'];

just try with concatenation like $fb->fileToUpload('"'.$imageName.'"');
