Привет, я здесь новичок, и мой вопрос может показаться раздражающим, но я просто сожалею
В своих достижениях я хочу запретить кнопку отправки нескольких запросов, чтобы транзакция моего клиента не запускалась несколько раз с использованием только php.
Мне удалось поймать кнопку отправки клиента с использованием кода
if(empty($_POST['key']) OR $_POST['key'] != $_SESSION['key'])
Но он возвращает true всегда
elseif(empty($_POST['key']) OR $_POST['key'] != $_SESSION['key'])
{
$form= 'multiples transaction accur either you double click the options or transaction is already in progress please try again ';
exit();
}
//This line also return true when $mey is greater than 1
elseif($mey > 1)
{
exit();
}
Поэтому я добавил exit(); к каждой строкекода, но он выходит из браузера и также возвращается как true, так как баланс моего кошелька клиента также вычитается.Что я делаю неправильно, это мой код ниже?Большое спасибо за ваше время и влияние на мое решение
Это мой код:
<?php
require('init.php');
error_reporting(0);
echo $_GET['type'];
if(!isset($_SESSION['count']))
{
$_SESSION['count'] = 0;
}
$vote = isset($_POST['button']) ? $_POST['button'] : false;
if($vote)
{
$mey = $_SESSION['count']++;
}
if($mey>1)
{
echo noo;
unset($_SESSION['count']);
}
$username = $_SESSION['user_name'];
$result = $conn->prepare('select * from users where username=:username');
$result->bindParam(':username', $username);
$result->execute();
while($row = $result->fetch(PDO::FETCH_BOTH))
{
$uid = $row['id'];
$username = $row['username'];
$ip = $row['ip'];
$ban = $row['validated'];
$balance = $row['balance'];
$pin = $row['pin'];
}
