Facebook messenger bot - receives single and very first message continuously at every 2 minutes.
I have created bot in PHP and set webhook. But I am receiving webhook trigger at every two minutes no matter I have added/received new message or not.
One more thing is that we are receiving only very first messages. There are so many new messages after that message but we are receiving single message only.
Where am I incorrect? I have followed this article :
http://blog.adnansiddiqi.me/develop-your-first-facebook-messenger-bot-in-php/
We got the solution:
$input = json_decode(file_get_contents('php://input'), true);
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
$message = isset($input['entry'][0]['messaging'][0]['message']['text']) ? $input['entry'][0]['messaging'][0]['message']['text'] : '';
if (!empty($input['entry'][0]['messaging'])) {
foreach ($input['entry'][0]['messaging'] as $message) {
$command = "";
// When bot receive message from user
if (!empty($message['message'])) {
$command = $message['message']['text'];
}
// When bot receive button click from user
else if (!empty($message['postback'])) {
$command = $message['postback']['payload'];
}
}
}
$pagetoken = "PAGE TOKEN"; // Facebook TOKEN
if ($command) {
if ($command == "hii") {
$message_to_reply = "test_response";
} else if ($command == "need more info") {
$message_to_reply = "Please fill form at link ";
} else if ($command == "\ud83d\ude00") {
$message_to_reply = "smiley";
}
if ($message_to_reply != "") {
$url = "https://graph.facebook.com/v2.6/me/messages?access_token=$pagetoken";
//Initiate cURL.
$ch = curl_init($url);
//The JSON data.
$jsonData = '{
"recipient":{
"id":"' . $sender . '"
},
"message":{
"text":"' . $message_to_reply . '"
}
}';
$jsonDataEncoded = $jsonData;
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
if (!empty($input['entry'][0]['messaging'][0]['message'])) {
$result = curl_exec($ch);
}
curl_close($ch);
}
}
header('HTTP/1.1 200 OK'); // This line needs to be added
die;
I'm trying to retrieve all members in a Facebook group getting this error:
array(5) {
["message"]=>
string(66) "An unexpected error has occurred. Please retry your request later."
["type"]=>
string(14) "OAuthException"
["is_transient"]=>
bool(true)
["code"]=>
int(2)
["fbtrace_id"]=>
string(11) "AnfsXcdgM"
}
Here is my code:
$this->_facebook = new Facebook\Facebook(array('app_id' => "$app_id",'app_secret' => "$secret",'default_graph_version' => 'v2.10'));
$this->_facebook->setDefaultAccessToken($_SESSION['facebook_access_token']);
$query = "/".$groupID."/members?fields=id,name,link,picture,first_name,last_name";
try{
$response = $this->_facebook->get($query);
while($pagesEdge)
{
$pageDecoded = json_decode($pagesEdge);
foreach($pageDecoded as $key => $member)
{
$id = $member->id;
}
}
}catch (Facebook\Exceptions\FacebookResponseException $e) { echo 'Graph returned an error: ' . $e->getMessage(); }
It works for groups with few hundreads of people (even once for a group with 10.000 members) but randomly I'm occurring to this.
This might be caused by a server side timeout. I get this error every now and then when I request a huge amount of data. Maybe you should try to limit your request by using the limit parameter (default should be 25).
I solved this by doing a cron that takes 100 data at the time and putting into a file text the value of the token for the next call.
I add this string on the query and when the fields inside $url are empty I quit my execution
<?php
public function updateGroupMembers($groupID)
{
$tempNext = file_get_contents($this->dirM); //check if the next string token is in the file
if (!empty($tempNext))
{
$queryUntil = $tempNext;
}
// Sets the default fallback access token so we don't have to pass it to each request
$this->_facebook->setDefaultAccessToken($_SESSION['facebook_access_token']);
// Create table name
$tableName = $groupID . "_Members";
// Query the Graph API to get all current member's ID and name
try
{
$query = "/".$groupID."/members?fields=id,name,link,picture,first_name,last_name".$queryUntil; //add the next string to my query
$response = $this->_facebook->get($query);
$pagesEdge = $response->getGraphEdge();
// Index for the elements fetched from the API below
$i = 0;
// Get current time
$pageDecoded = json_decode($pagesEdge);
foreach($pageDecoded as $key => $member)
{
/* ...get data and process them... */
}
$temp = $pagesEdge->getMetaData();
$next = parse_url($temp['paging']['next']);
parse_str($next['query'], $url);
$access_token = '&access_token='.$url['access_token'];
$fields = '&fields='.$url['fields'];
$limit = '&limit=100';
$after = '&after='.$url['after'];
$res['until'] = $access_token.$fields.$limit.$after;
file_put_contents($this->dirM, $res['until'], LOCK_EX);
if ( empty($url['access_token']) || empty($url['fields']) || empty($url['limit']) || empty($url['after']) )
{
file_put_contents($this->dirM, '', LOCK_EX); //clean my txt file that contains my next string
die('FINE');
}
} catch (Facebook\Exceptions\FacebookResponseException $e) {
echo 'm2Graph returned an error: ' . $e->getMessage();
exit;
} catch (Facebook\Exceptions\FacebookSDKException $e) {
echo 'm2Facebook SDK returned an error: ' . $e->getMessage();

thank you
so I've been trying to set up Paypal IPN, and been trying tonnes of different solutions to get my IPN to validate. For some reason, it works fine when I'm using Sanbox paypal, but as soon as I try to use the live version, nothing happens. No error logs, no IPN logs, nothing. I'm just lost.
I was wondering if any new eyes would spot the problem. Here's my paypal.php class:
<?php
session_start();
$base = "/var/www/html/";
include("db.php");
require_once('paypal.class.php'); // include the class file
$p = new paypal_class; // initiate an instance of the class
//$p->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; // testing paypal url
$p->paypal_url = 'https://www.paypal.com/cgi-bin/webscr'; // paypal url
// setup a variable for this script (ie: 'http://www.micahcarrick.com/paypal.php')
$this_script = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
// if there is not action variable, set the default action of 'process'
if (empty($_GET['action'])) $_GET['action'] = 'process';
if (empty($_GET['amm'])) $_GET['amm'] = '1';
$EMAIL = 'emailaddresshere';
switch ($_GET['action']) {
case 'process': // Process and order...
if (empty($_GET['prod'])){
header("Location: confirm-product.php"); //Was donate.php (but no file for that, so might be confirm-product)
exit;
}
if (empty($_GET['username'])){
if($_GET['action'] = 'process'){
header("Location: confirm-product.php"); // was donate.php as well
exit;
}
}
//if(!isset($_SESSION["username"])) {
// header("Location: login.php");
// exit;
//}
//include("include.php");
//die("donation is temporarily disabled!");
// There should be no output at this point. To process the POST data,
// the submit_paypal_post() function will output all the HTML tags which
// contains a FORM which is submited instantaneously using the BODY onload
// attribute. In other words, don't echo or printf anything when you're
// going to be calling the submit_paypal_post() function.
// This is where you would have your form validation and all that jazz.
// You would take your POST vars and load them into the class like below,
// only using the POST values instead of constant string expressions.
// For example, after ensureing all the POST variables from your custom
// order form are valid, you might have:
//
// $p->add_field('first_name', $_POST['first_name']);
// $p->add_field('last_name', $_POST['last_name']);

I'm using this below code so that i get hte request id when my friends accepts my invite but how do i get my uid.
Say I'm A.A sends invite to b.When b ,accepts ,i can get request id but how do i get A UID
//get the request ids from the query parameter
$request_ids = explode(',', $_REQUEST['request_ids']);
//build the full_request_id from request_id and user_id
function build_full_request_id($request_id, $user_id) {
return $request_id . '_' . $user_id;
}
//for each request_id, build the full_request_id and delete request
foreach ($request_ids as $request_id)
{
echo ("reqeust_id=".$request_id."<br>");
$full_request_id = build_full_request_id($request_id, $user_id);
echo ("full_request_id=".$full_request_id."<br>");
try {
$delete_success = $facebook->api("/$full_request_id",'DELETE');
if ($delete_success) {
echo "Successfully deleted " . $full_request_id;}
else {
echo "Delete failed".$full_request_id;}
}
catch (FacebookApiException $e) {
echo "error";}
}
When you make a GET call to /{request_id} you get back the sender and recipient uids
Try $user_id = $facebook->getUser();
edit: looking back at your code, I see you already use $user_id, so isn't that the ID you need?
