Upload and share

[Ex1t]

I have image upload script, now i want that when I upload new image to my site to share automatically on facebook page, can i make some simple script for that operation?

Can someone give me simple code for that?

Facebook has their sdk, app, and tokens to share on their site.

https://developers.facebook.com/docs/reference/php/5.0.0

 

Then there is the sharing.

Yeah i checked that, but i dont know how to implement that in my code..

No one is going to give you the code - coding is what most of us get paid to do. Start with the APIs and documentation that QuickOldCar link to above, Google, and try some things. When you get stuck, come on here and tell us what you've tried, show us the code you've written, and we'll help where we can.

Okay, so i dont know to work with API but im trying

So this is my simple code

<form action="" method="post">
<input type="file" name="fileToUpload">
<button>Upload</button>
</form>


<?php

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
    $fb = new Facebook\Facebook([
 'app_id' => 'myappid',
 'app_secret' => 'myappsecret',
 'default_graph_version' => 'v2.4',
 ]);

$data = [
 'message' => 'My awesome photo upload example.',
 'source' => $fb->fileToUpload($target_dir),
];

try {
 // Returns a `Facebook\FacebookResponse` object
 $response = $fb->post('/me/photos', $data, 'myaccesstoken');
} 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'];
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

?>

I got this error message
 

Notice: Undefined index: fileToUpload in C:\wamp\www\fb.php on line 10

What is wrong in code for upload?

Btw. are code for facebook API good?

I fixed last error, but I got this error now

 Fatal error: Class 'Facebook\Facebook' not found in C:\wamp\www\fb_upload.php on line 223

1 - you are using $_POST in your code but since your form doesn't have a method set the $_POST array won't have your inputs

2 - You also reference an input name of 'submit' but I don't see that in your form

3 - I don't see where you included the class so that could certainly explain your new error now as well as the above two items.

4 - add php error checking to help you debug what will probably be many future errors. See my signature.

I have included now all required files from https://github.com/facebook/facebook-php-sdk-v4

 

But i still get some errors, i have fix it 1 by 1 but still and still getting new errors for including and others..

Did you fix the problems I pointed out? When you do how about isolating the new problem area(s) and posting those snippets of code for us to address? I, for one, will not be going to your external post no matter where it is hosted, so I won't be any help until you do the necessary work to get close to your problem and ask a pertinent question.
