Yelp API - Getting JSON Results - php

I'm new to JSON and Yelp's API. I'm trying to search the API with a form. Here's my HTML:
<div>
<form action="sample.php" method="post">
<label>Term</label> <input name="term" id="term" type="text"/>
<label>Location</label> <input name="location" id="location" type="text"/>
<input id="submit" type="submit" name="submitRest" value="SUBMIT">
</form>
<div id="success"></div>
<div id="result">Result</div>
</div>
I'm submitting the form via ajax here:
<script type="text/javascript">
$('form').submit(function(evt){
evt.preventDefault();
var url = $(this).attr("action");
var formData = $(this).serialize();
$.ajax(url, {
data : formData,
type : "POST",
success : function(response){
$('#success').html("<p>It worked!</p><p>" + <?php $getYelpData ?> + "</p>")
}
});
});
</script>
The problem lies in "sample.php". It consists of this Oauth call:
require_once('lib/OAuth.php');
$Term = (isset($_POST['term'])) ? $_POST['term'] : '';
$Location = (isset($_POST['location'])) ? $_POST['location'] : '';
function getYelpData($Term, $Location) {
$URL = "http://api.yelp.com/v2/search?term=" . $Term . "&location=" . $Location;
$CONSUMER_KEY = -;
$CONSUMER_SECRET = -;
$TOKEN = -;
$TOKEN_SECRET = -;
$AuthToken = new OAuthToken($TOKEN, $TOKEN_SECRET);
$Consumer = new OAuthConsumer($CONSUMER_KEY, $CONSUMER_SECRET);
$AuthRequest = OAuthRequest::from_consumer_and_token(
$Consumer,
$AuthToken,
'GET',
$URL
);
$AuthRequest->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $Consumer, $AuthToken);
$Handle = curl_init($AuthRequest->to_url());
curl_setopt($Handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($Handle, CURLOPT_HEADER, 0);
$YelpResponse = curl_exec($Handle); // Yelp response
curl_close($Handle);
return json_decode($YelpResponse,true);
}
How do I grab the JSON data from $YelpResponse? The ajax displays the success message, so I know it's working, but I'm not sure how to get the data I want out of it.

User unable to try login again if he type wrong details

I have a login form with recaptcha 3 script.
When user type his right details he login in successfully. But if he wrong the recaptcha doesn't allow him to try again and print my error: 'recaptcha_error(2)'

how to Getting error when submitting a form by ajax to page msg.php
The name of the variable is the error = $error
collect errors in php script as $errors array, then finaly ouput it as JSON:
print json_encode($errors);
and process it in success event handler
<script>
$( '#my-form' )
.submit( function( e ) {
$.ajax({
url: 'chat_a.php',
type: 'POST',
data: new FormData( this ),
processData: false,
contentType: false,
success: function(msg)
{
json = $.parseJSON(msg);
if (json.error[1] != "") //
$("#div-error-1").html(json.error[1]);
if (json.error[2] != "") //
$("#div-error-2").html(json.error[2]);
// and so on. Or you can use foreach construction. it will make code more universal
}
} );
e.preventDefault();
document.getElementById("my-form").reset();
});
</script>

Updating JSON file with PHP & AJAX

I'm making a game and to use it, you must register. So I'm trying to append a username and password that has been entered into a form to my JSON file which looks like:
{
"LogIns":[
{
"Username":"mikehene",
"password":"123"
},
{
"Username":"mike",
"password":"love"
}
]
}
My PHP reads:
<?php
$username = $_POST['username'];
$password = $_POST['password'];
$str = file_get_contents('logins.json'); // Save contents of file into a variable
$json = json_decode($str, true); // decode the data and set it to recieve data asynchronosly - store in $json
array_push($json, $username, $password);
$jsonData = json_encode($json);
file_put_contents('logins.json', json_encode($json));
?>
AJAX:
function callAJAX(){
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange=function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
console.log(xhttp.responseText);
document.getElementById("PHPid").innerHTML = xhttp.responseText;
}
}
xhttp.open("POST", "reg.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("username=" + usernamePassed + "&password="+ userPassword);
}
HTML:
<fieldset>
<legend>Please register before playing</legend>
<form>
Username: <br>
<input type="text" placeholder="Enter a Username" id="username1" name="username"><br>
Password: <br>
<input type="password" placeholder="Enter a password" id="password" name="password"><br>
<input type="submit" value="Submit" onclick="return checkLogin();">
</form>
</fieldset>
<div id="PHPid"><div>
<script>
var usernamePassed = '';
var userPassword = "";
function checkLogin(){
usernamePassed = document.getElementById("username1").value;
userPassword = document.getElementById("password").value;
console.log(usernamePassed);
console.log(userPassword);
callAJAX();
return false;
}
function callAJAX(){
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange=function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
console.log(xhttp.responseText);
document.getElementById("PHPid").innerHTML = xhttp.responseText;
}
}
xhttp.open("POST", "reg.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("username=" + usernamePassed + "&password="+ userPassword);
</script>
So for example if I inputted username: mike, password:123 into the HTML field it should update my json file but my json file is not changing.
I'm running it on localhost and I have checked the permissions, which are set to read and write for all users.
Any ideas why?
Thanks in advance
The problem here is that you are missing a closing brace } for your callAJAX() function.
Having looked at your developer console, you would have seen the following:
SyntaxError: missing } after function body
Fixed script code:
<script>
var usernamePassed = '';
var userPassword = "";
function checkLogin(){
usernamePassed = document.getElementById("username1").value;
userPassword = document.getElementById("password").value;
console.log(usernamePassed);
console.log(userPassword);
callAJAX();
return false;
}
function callAJAX(){
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange=function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
console.log(xhttp.responseText);
document.getElementById("PHPid").innerHTML = xhttp.responseText;
}
}
xhttp.open("POST", "reg.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("username=" + usernamePassed + "&password="+ userPassword);
}
</script>
- Using a code editor with bracket/brace matching, would have helped ;-)
You are already using one as pointed out in comments.
What I tested this with was:
<fieldset>
<legend>Please register before playing</legend>
<form>
Username: <br>
<input type="text" placeholder="Enter a Username" id="username1" name="username"><br>
Password: <br>
<input type="password" placeholder="Enter a password" id="password" name="password"><br>
<input type="submit" value="Submit" onclick="return checkLogin();">
</form>
</fieldset>
<div id="PHPid"><div>
<script>
var usernamePassed = '';
var userPassword = "";
function checkLogin(){
usernamePassed = document.getElementById("username1").value;
userPassword = document.getElementById("password").value;
console.log(usernamePassed);
console.log(userPassword);
callAJAX();
return false;
}
function callAJAX(){
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange=function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
console.log(xhttp.responseText);
document.getElementById("PHPid").innerHTML = xhttp.responseText;
}
}
xhttp.open("POST", "reg.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("username=" + usernamePassed + "&password="+ userPassword);
}
</script>
and
<?php
$username = $_POST['username'];
$password = $_POST['password'];
$str = file_get_contents('logins.json'); // Save contents of file into a variable
$json = json_decode($str, true); // decode the data and set it to recieve data asynchronosly - store in $json
array_push($json, $username, $password);
$jsonData = json_encode($json);
file_put_contents('logins.json', json_encode($json));
?>

How to validate Google reCAPTCHA v3 on server side?

I've just set up the new google recaptcha with checkbox, it's working fine on front end, however I don't know how to handle it on server side using PHP. I've tried to use the old code below but the form is sent even if the captcha is not valid.
require_once('recaptchalib.php');
$privatekey = "my key";
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
$errCapt='<p style="color:#D6012C ">The CAPTCHA Code wasnot entered correctly.</p>';}
Private key safety
While the answers here are definately working, they are using a GET request, which exposes your private key (even though https is used). On Google Developers the specified method is POST.
For a little bit more detail: https://stackoverflow.com/a/323286/1680919
Verification via POST
function isValid()
{
try {
$url = 'https://www.google.com/recaptcha/api/siteverify';
$data = ['secret' => '[YOUR SECRET KEY]',
'response' => $_POST['g-recaptcha-response'],
'remoteip' => $_SERVER['REMOTE_ADDR']];
$options = [
'http' => [
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
]
];
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return json_decode($result)->success;
}
catch (Exception $e) {
return null;
}
}
Array Syntax: I use the "new" array syntax ( [ and ] instead of array(..) ). If your php version does not support this yet, you will have to edit those 3 array definitions accordingly (see comment).
Return Values: This function returns true if the user is valid, false if not, and null if an error occured. You can use it for example simply by writing if (isValid()) { ... }
this is solution

I'm not a fan of any of these solutions. I use this instead:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
'secret' => $privatekey,
'response' => $_POST['g-recaptcha-response'],
'remoteip' => $_SERVER['REMOTE_ADDR']
]);
$resp = json_decode(curl_exec($ch));
curl_close($ch);
if ($resp->success) {
// Success
} else {
// failure
}
I'd argue that this is superior because you ensure it is being POSTed to the server and it's not making an awkward 'file_get_contents' call. This is compatible with recaptcha 2.0 described here: https://developers.google.com/recaptcha/docs/verify
I find this cleaner. I see most solutions are file_get_contents, when I feel curl would suffice.
Easy and best solution is the following.
index.html
<form action="submit.php" method="POST">
<input type="text" name="name" value="" />
<input type="text" name="email" value="" />
<textarea type="text" name="message"></textarea>
<div class="g-recaptcha" data-sitekey="Insert Your Site Key"></div>
<input type="submit" name="submit" value="SUBMIT">
</form>
submit.php
<?php
if(isset($_POST['submit']) && !empty($_POST['submit'])){
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
//your site secret key
$secret = 'InsertSiteSecretKey';
//get verify response data
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
$responseData = json_decode($verifyResponse);
if($responseData->success){
//contact form submission code goes here
$succMsg = 'Your contact request have submitted successfully.';
}else{
$errMsg = 'Robot verification failed, please try again.';
}
}else{
$errMsg = 'Please click on the reCAPTCHA box.';
}
}
?>
I have found this reference and full tutorial from here - Using new Google reCAPTCHA with PHP
I liked Levit's answer and ended up using it. But I just wanted to point out, just in case, that there is an official Google PHP library for new reCAPTCHA: https://github.com/google/recaptcha
The latest version (right now 1.1.2) supports Composer and contains an example that you can run to see if you have configured everything correctly.
Below you can see part of the example that comes with this official library (with my minor modifications for clarity):
// Make the call to verify the response and also pass the user's IP address
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);
if ($resp->isSuccess()) {
// If the response is a success, that's it!
?>
<h2>Success!</h2>
<p>That's it. Everything is working. Go integrate this into your real project.</p>
<p>Try again</p>
<?php
} else {
// If it's not successful, then one or more error codes will be returned.
?>
<h2>Something went wrong</h2>
<p>The following error was returned: <?php
foreach ($resp->getErrorCodes() as $code) {
echo '<tt>' , $code , '</tt> ';
}
?></p>
<p>Check the error code reference at <tt>https://developers.google.com/recaptcha/docs/verify#error-code-reference</tt>.
<p><strong>Note:</strong> Error code <tt>missing-input-response</tt> may mean the user just didn't complete the reCAPTCHA.</p>
<p>Try again</p>
<?php
}
Hope it helps someone.
To verify at server side using PHP. Two most important thing you need to consider.
1. $_POST['g-recaptcha-response']
2.$secretKey = '6LeycSQTAAAAAMM3AeG62pBslQZwBTwCbzeKt06V';
$verifydata = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secretKey.'&response='.$_POST['g-recaptcha-response']);
$response= json_decode($verifydata);
If you get $verifydata true, You done.
For more check out this
Google reCaptcha Using PHP | Only 2 Step Integration
In the example above. For me, this if($response.success==false) thing does not work. Here is correct PHP code:
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "--your_key--";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if (isset($data->success) AND $data->success==true) {
// everything is ok!
} else {
// spam
}
it is similar with mattgen88, but I just fixed CURLOPT_HEADER, and redefine array for it work in domain.com host server. this one doesn't work on my xampp localhost. Those small error but took long to figure out. this code was tested on domain.com hosting.
$privatekey = 'your google captcha private key';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_HEADER, 'Content-Type: application/json');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'secret' => $privatekey,
'response' => $_POST['g-recaptcha-response'],
'remoteip' => $_SERVER['REMOTE_ADDR']
)
);
$resp = json_decode(curl_exec($ch));
curl_close($ch);
if ($resp->success) {
// Success
echo 'captcha';
} else {
// failure
echo 'no captcha';
}
Here you have simple example. Just remember to provide secretKey and siteKey from google api.
<?php
$siteKey = 'Provide element from google';
$secretKey = 'Provide element from google';
if($_POST['submit']){
$username = $_POST['username'];
$responseKey = $_POST['g-recaptcha-response'];
$userIP = $_SERVER['REMOTE_ADDR'];
$url = "https://www.google.com/recaptcha/api/siteverify?secret=$secretKey&response=$responseKey&remoteip=$userIP";
$response = file_get_contents($url);
$response = json_decode($response);
if($response->success){
echo "Verification is correct. Your name is $username";
} else {
echo "Verification failed";
}
} ?>

Not able to send messages via GCM

I am using a PHP script to push messages onto android devices via GCM. I have an html form that takes in a text input as the message and then pushes this message to the android device.
Now when i tried it with two separate fields 1. Excerpt 2. Message
My android device receives a null message.
I need to know where am I going wrong.
This is my HTML Form
<form id="<?php echo $row["id"] ?>" name="" method="post" onsubmit="return sendPushNotification('<?php echo $row["id"] ?>')">
<label>User:</label> <span><?php echo $row["id"] ?></span>
<div class="clear"></div>
<div class="send_container">
<textarea rows="3" name="excerpt" cols="10" class="txt_excerpt" placeholder="Type excerpt here"></textarea>
<textarea rows="3" name="message" cols="25" class="txt_message" placeholder="Type message here"></textarea>
<input type="hidden" name="regId" value="<?php echo $row["gcm_regid"] ?>"/>
<input type="submit" class="send_btn" value="Send" onclick=""/>
</div>
</form>
This is the ajax Script
<script type="text/javascript">
$(document).ready(function(){
});
function sendPushNotification(id){
var data = $('form#'+id).serialize();
$('form#'+id).unbind('submit');
$.ajax({
url: "send_message.php",
type: 'GET',
data: data,
beforeSend: function() {
},
success: function(data, textStatus, xhr) {
$('.txt_message').val("");
$('.txt_excerpt').val("");
},
error: function(xhr, textStatus, errorThrown) {
}
});
return false;
}
</script>
This is the Send_message.php code
if (isset($_GET["regId"]) && isset($_GET["message"]) && isset($_GET["excerpt"])) {
$regId = $_GET["regId"];
$message = $_GET["message"];
$excerpt = $_GET["excerpt"];
include_once './GCM.php';
$gcm = new GCM();
$registatoin_ids = array($regId);
$message = array("news" => $message, "exc" => $excerpt);
$result = $gcm->send_notification($registatoin_ids, $message);
echo $result;
This is the GCM.php Code
public function send_notification($registatoin_ids, $message, $excerpt) {
// include config
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
This is the android GCMIntentService Code
#Override
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
String message = intent.getExtras().getString("news");
String excerpt = intent.getExtras().getString("exc");
Log.i("Received ->", excerpt+" "+message);
if(message!=null)
{
displayMessage(context, message);
// notifies user
generateNotification(context, message);
}
}
All I see on my device is a blank notification whenever I push a message from the server.
