Check for a database update using PHP and AJAX - javascript

I have a website where when the user clicks a canvas, he draws on it and it gets pushed into the database. And it draws for every user 10 times in one second.
setInterval(function(){
$.ajax({
url: 'data/canvasSave.php',
success: function(data) {
$('.result').html(data);
console.log(data);
imageCanvas = data;
}
});
let img = new Image();
img.src = imageCanvas;
context.clearRect(0, 0, canvas.width, canvas.height);
ctx.drawImage(img, 0 , 0, canvas.width, canvas.height);
}, 100);
Now I notice that this isn't the best way. But is there a good way to check for Database updates?
I tried a few if statements but none of them really worked.

You can use PHP sockets for tracking MySQL Database changes with WebSockets.
Setup Frontend
File: index.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/uikit#3.7.4/dist/css/uikit.min.css" />
</head>
<body>
<div class="uk-container uk-padding">
<h2>Users</h2>
<p>Tracking users table with WebSockets</p>
<table class="uk-table">
<thead>
<tr>
<th>User ID</th>
<th>User Name</th>
</tr>
</thead>
<tbody>
<?php
$connection = mysqli_connect(
'localhost',
'root',
PASSWORD,
DB_NAME
);
$users = mysqli_query($connection, 'SELECT * FROM users');
while ($user = mysqli_fetch_assoc($users)) {
echo '<tr>';
echo '<td>' . $user['id'] . '</td>';
echo '<td>' . $user['name'] . '</td>';
echo '</tr>';
}
?>
</tbody>
</table>
</div>
</body>
</html>
Next, add the PieSocket-JS WebSocket library in your HTML file with the following code:
Now, we are ready to connect to the WebSocket channel and start receiving instantaneous updates from the server. Add the following code to your index.php file to make a websocket connection.
<script>
var piesocket = new PieSocket({
clusterId: 'CLUSTER_ID',
apiKey: 'API_KEY'
});
// Connect to a WebSocket channel
var channel = piesocket.subscribe("my-channel");
channel.on("open", ()=>{
console.log("PieSocket Channel Connected!");
});
//Handle updates from the server
channel.on('message', function(msg){
var data = JSON.parse(msg.data);
if(data.event == "new_user"){
alert(JSON.stringify(data.data));
}
});
</script>
Setup Backend
Let’s create a file called admin.php which adds an entry to the user’s table, every time it is visited.
<?php
$connection = mysqli_connect(
'localhost',
'root',
PASSWORD,
DB_NAME
);
mysqli_query($connection, "INSERT INTO users .....");
?>
The code snippet given above adds an entry in the users table every time its execute either via CLI or from a webserver.
Use the following PHP function to do that.
<?php
function publishUser($event){
$curl = curl_init();
$post_fields = [
"key" => "PIESOCKET_API_KEY",
"secret" => "PIESOCKET_API_SECRET",
"channelId" => "my-channel",
"message" => $event
];
curl_setopt_array($curl, array(
CURLOPT_URL => "https://PIESOCKET_CLUTER_ID.piesocket.com/api/publish",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => json_encode($post_fields),
CURLOPT_HTTPHEADER => array(
"Content-Type: application/json"
),
));
$response = curl_exec($curl);
print_r($response);
}
$connection = mysqli_connect(
'localhost',
'root',
PASSWORD,
DB_NAME
);
mysqli_query($connection, "INSERT INTO users .....");
$payload = json_encode([
"event" => "new_user",
"data" => [
"id"=> 1,
"name"=>"Test user"]
]);
publishUser($payload);
?>
Track MySQL changes in real-time with Laravel
For example, in your User model under app/model/User.php add the following code block
public static function boot() {
parent::boot();
static::created(function($user) {
publishUser(json_encode($user));
});
}
Track MySQL changes in real-time with Django
import requests
import json
url = "https://CLUSTER_ID.piesocket.com/api/publish"
payload = json.dumps({
"key": "API_KEY",
"secret": "API_SECRET",
"channelId": 1,
"message": { "text": "Hello world!" }
});
headers = {
'Content-Type': 'application/json'
}
response = requests.request("POST", url, headers=headers, data = payload)
print(response.text.encode('utf8'))

i need help with product detail , customer name , amount on success page and if possible payment paid or not paid status on it.... cant find any tutorial on it or any detail step by step guide on it
i am close but cant get it to bullseyes please help me with it
yeah on success page all i get is payment status and blank
Looks like here is what happened:
Your Checkout Session defined success_url to success.html
Your success.html fired another request to "/success?session_id=xxx"
Your backend handled this with $app->get('/success', function...
It could be confusing to name both HTML in step 2 and the handling URL in step 3 as "success". You may want to use a different name such as "success" and "get-checkout-session" like Stripe example on Github. After that, debug your server log on step 3 to see whether you got the session id correctly and have retrieved the Customer Id.
There is more information to extract from a CheckoutSession. See Stripe's API Reference on available properties. You probably want to expand its payment_intent to see the amount and payment status.

Stripe: Meta Data from HTML to Checkout-Sessions PHP

I use the samples (https://github.com/stripe-samples/checkout-single-subscription/tree/master/server/php) from Stripe to create a subscription. What I don't really understand, how can I pass metadata from my index.html over script.js to the create-checkout-session.php.
I thought I just add data attributes to the index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Stripe</title>
<meta name="description" content="A demo of Stripe Payment Intents" />
<link rel="icon" href="favicon.ico" type="image/x-icon" />
<script src="https://js.stripe.com/v3/"></script>
<script src="./script.js" defer></script>
</head>
<body>
<div class="sr-root">
<div class="sr-main" style="display: flex;">
<div class="sr-container">
<section class="container">
<button id="basic-plan-btn" data-partner="name" data-package="basic">USD 6.90</button>
</section>
<section class="container">
<button id="pro-plan-btn" data-partner="name" data-package="premium">USD 11.90</button>
</section>
</div>
</div>
</div>
</body>
</html>
then I have to read them somehow out in the script.js. But that I don't really figure out how.
// Create a Checkout Session with the selected plan ID
var createCheckoutSession = function(priceId) {
return fetch("/fileadmin/restaurant/stripe/create-checkout-session.php", {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify({
priceId: priceId,
partner: 'name',
package: 'premium'
})
}).then(function(result) {
return result.json();
});
};
// Handle any errors returned from Checkout
var handleResult = function(result) {
if (result.error) {
var displayError = document.getElementById("error-message");
displayError.textContent = result.error.message;
}
};
/* Get your Stripe publishable key to initialize Stripe.js */
fetch("/fileadmin/restaurant/stripe/config.php")
.then(function(result) {
return result.json();
})
.then(function(json) {
var publishableKey = json.publishableKey;
var basicPriceId = json.basicPrice;
var proPriceId = json.proPrice;
var stripe = Stripe(publishableKey);
// Setup event handler to create a Checkout Session when button is clicked
document
.getElementById("basic-plan-btn")
.addEventListener("click", function(evt) {
createCheckoutSession(basicPriceId).then(function(data) {
// Call Stripe.js method to redirect to the new Checkout page
stripe
.redirectToCheckout({
sessionId: data.sessionId
})
.then(handleResult);
});
});
// Setup event handler to create a Checkout Session when button is clicked
document
.getElementById("pro-plan-btn")
.addEventListener("click", function(evt) {
createCheckoutSession(proPriceId).then(function(data) {
// Call Stripe.js method to redirect to the new Checkout page
stripe
.redirectToCheckout({
sessionId: data.sessionId
})
.then(handleResult);
});
});
});
by that I receive them in the create-checkout-session.php
<?php
require_once 'shared.php';
$domain_url = $config['domain'];
$checkout_session = \Stripe\Checkout\Session::create([
'success_url' => $domain_url . 'success.php?session_id={CHECKOUT_SESSION_ID}',
'cancel_url' => $domain_url . 'canceled.php',
'payment_method_types' => ['card'],
'mode' => 'subscription',
'allow_promotion_codes' => true,
'line_items' => [[
'price' => $body->priceId,
'quantity' => 1,
]],
'subscription_data' => ['trial_period_days' => 60],
'metadata' => [
'partner' => $body->partner,
'package' => $body->package
],
]);
echo json_encode(['sessionId' => $checkout_session['id']]);
Thank You.
What you've done adding to the JSON body of the fetch call looks right to me. If you're trying to set the 'name' and 'premium' values dynamically from some input, then take a look at this previous answer for some approaches for getting input values.

How do I properly pass an PHP array to Leatlef Heatmap?

I am new to PHP and MySQL, so this task really keeps me struggling:
I have an MySQL database which contains a lot of geo coordinates which shall be extracted by php, transformed to JSON format to pass them to JavaScript and then be displayed in Leaflet's heatmap.
I already wrote the JS code, and the AJAX seems to be functioning. But Heatmap does not seem to be accepting my array containing the coordinates. I can't see where I made an mistake; I think my PHP array is not formatted in the right way.
Heatmap needs to get its data in this format:
var testData = {
max: 8,
data: [{lat: 24.6408, lng:46.7728, count: 1},{lat: 50.75, lng:-1.55, count: 1}, ...]
};
This is my code by now:
var geoData;
function loadData() {
alert("loading Data");
getJSON();
}
function getJSON() {
$.ajax({
url: "assets/php/readGeoData.php",
type: "GET",
datatype: "json",
success: function(data) {
alert("ajax transfer successful ");
geoData = data;
//For debugging:
alert(getGeoData());
}
})
}
function getGeoData() {
return geoData;
}

PHP:
<?php
$db = new PDO('mysql:host=127.0.0.1;dbname=movementprofile;', 'root', *****);
$query ='SELECT longitude, latitude FROM movementprofile WHERE longitude IS NOT NULL AND latitude IS NOT NULL';
foreach ($db->query($query) as $row) {
print_r($row);
$longitude = $row['longitude'];
$latitude = $row['latitude'];
$singleDataset = array('lon' => $longitude,'lat' => $latitude, 'count'=> 1);
array_push($datasets,$singleDataset, JSON_FORCE_OBJECT);
echo json_encode($datasets);
}
This is the array I get right now (in the JS alert box):
Array
(
[longitude] => 13.39611111
[0] => 13.39611111
[latitude] => 52.52944444
[1] => 52.52944444
)
nullArray
(
[longitude] => 13.37472222
[0] => 13.37472222
[latitude] => 52.53027778
[1] => 52.53027778
)
nullArray
(
[longitude] => 13.38361111
[0] => 13.38361111
[latitude] => 52.53
[1] => 52.53
)
//... and so on, there are more than 30.000 entries
So, how do I get this array to look like the one Heatmap needs?
EDIT:
So I edited my PHP to this:
foreach ($db->query($query) as $row) {
print_r($row);
$longitude = $row['longitude'];
$latitude = $row['latitude'];
$singleDataset = array('lon' => $longitude,'lat' => $latitude, 'count'=> 1);
array_push($datasets,json_encode($singleDataset));
But still got this array:
Array
(
[longitude] => 13.39611111
[0] => 13.39611111
[latitude] => 52.52944444
[1] => 52.52944444
)
//and so on
# thinsoldier
Did you mean that?
First thing I see in your code is that you do print_r($row); - remove or comment that.
Also maybe take a look at my php connector how to create geojson (example connects with postgres but you can simply rewrite that to mysql and adjust to your database structure):
<?php
$dbconn = pg_connect("host=localhost port=5432 dbname=pguser user=pguser password=pass");
$result = pg_query($dbconn, "SELECT * FROM test");
$geojson = array(
'type' => 'FeatureCollection',
'features' => array()
);
while($row = pg_fetch_assoc($result)) {
$feature = array(
'id' => $row['id'],
'type' => 'Feature',
'geometry' => array(
'type' => 'Point',
'coordinates' => array($row['latitude'], $row['longitude'])
),
# Pass other attribute columns here
'properties' => array(
'test' => 'test',
'column1' => $row['column1'],
'column2' => $row['column2']
)
);
# Add feature arrays to feature collection array
array_push($geojson['features'], $feature);
}
header('Content-type: application/json');
echo json_encode($geojson, JSON_NUMERIC_CHECK);
?>
EDIT
Because you want to get specific structure of json, not geoJson with features, above code may be simplified to:
....
$json = array(
'max' => '8',
'data' => array()
);
while($row = pg_fetch_assoc($result)) {
$data = array(
'lat' => $row['latitude'],
'lng' => $row['longitude'],
'count' => '1',
);
# Add feature arrays to feature collection array
array_push($json['data'], $data);
}
header('Content-type: application/json');
echo json_encode($json, JSON_NUMERIC_CHECK);
....

Bar graph rows in the database and order by status, using jscharts and php

I need help debugging this prob, I'm using javascript and php
here are my files
data.php -> display the data from database
bargraph.html -> bar graph display
chart.min.js, jquery-3.2.1.min.js, and my defined js file app.js - js files
The problem is that I wanted bar graph display of database's reservation status. (Pending, Accepted, Cancelled) but the bar graph only shows the highest number of the reference_id in the database
The database table have these data inside:
column: reference_id, reservation_status
1. reference_id = "1", reservation_status = "Accepted"
2. reference_id = "2", reservation_status = "Pending"
3. reference_id = "3", reservation_status = "Accepted"
but the output shows the Accepted reference_id = "3" as the highest number and doesn't show the pending
I wanted my output to show that there are two rows in the database that is "Accepted" and one row that is "Pending"
So the score for the Accepted should be = 2
and Pending is = 3
here are my files.
data.php
<?php
//setting header to json
header('Content-Type: application/json');
//database
define('DB_HOST', '127.0.0.1');

}
//query to get data from the table

//execute query
$result = $mysqli->query($query);
//loop through the returned data
$data = array();
foreach ($result as $row) {
$data[] = $row;
}
//free memory associated with result

UTF8 characters not displaying properly with datatables and yadcf

I have a mysql database that is in UTF8, I've properly output the letters before but cannot make my php do so with datatables using the ajax process. I have tried various methods to get the UTF8 to show, including, changing headers, using mysql functions, and changing the json encode function, but I cannot make it work. Please help me show UTF8 properly instead of ?s.
I have: temps.php
My server side processing script:
<?php
header("Content-Type: text/json; charset=utf-8");
require( 'ssp.class.php' );
$table = 'articles';
$primaryKey = 'id';
$columns = array(
array( 'db' => 'title', 'dt' => 0 ),
array( 'db' => 'description', 'dt' => 1 ));
$sql_details = array(
'user' => 'root', 'pass' => 'pass', 'db' => 'test', 'host' => 'localhost'
);
$db = SSP::db($sql_details);
.....
if($clause !== ""){
$whereAll[] = $clause;
$_GET['columns'][$i]['search']['value'] = "";
}}
echo json_encode(
SSP::complex( $_GET, $db, $table, $primaryKey, $columns, null,
(!empty($whereAll) ? implode(" AND ", $whereAll) : "")
));
I have: temp.html: My Javascript function (based on datatables and yadcf)
$(document).ready(function(){
$("#example").dataTable({
"responsive": true,
"processing": true,
"serverSide": true,
"ajax": "scripts/temps.php",
"columns": [
// ID
null,
// Distributor
null
// Director
]
}).yadcf([
// ID
{
column_number: 0 ,
filter_type: "text",
filter_reset_button_text: false
},
// Abstract
{
column_number: 1,
filter_type: "text",
filter_delay: 500,
filter_reset_button_text: false
},
]);
});
And I have temp.html where the data is outputted: (redacted because a lot of the code is irrelevant to the question)
<!DOCTYPE html>
<div>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

<thead>
<tr>
<th><div>One</div></th>
<th><div>Two</div></th>
</tr>
</thead>
</table>
Sorry for such a long question; but what else can I change to make UTF8 properly show on the html page? I've tried all the combinations of variables and functions I can think of; but can't make it work. Perhaps there is a js function that could be applied somewhere? Thank you for the help.
Edit: SQL structure for reference:

`id` int(11) NOT NULL,

You need to force utf8 in the PDO connection :
$db = SSP::db($sql_details);
$db->exec("set names utf8");
alternatively, try pass it as a param :
$sql_details = array(
'user' => 'root',
'pass' => 'ryan',
'db' => 'edata',
'host' => 'localhost',
'charset' => 'utf8'
);
But this does not work with all PHP versions.
PS: Why do you set the table fields to be of type utf8, but the table character set to be latin1?
If you have added all the columns as "UTF-8" and still the problem persists then try this
Add these lines on the server side file
mysql_query("SET character_set_client=utf8",$gaSql['link']);
mysql_query("SET character_set_connection=utf8",$gaSql['link']);
mysql_query("SET character_set_results=utf8",$gaSql['link']);
