I have a system where you have registered items and the logged in user tries to hit the results of those matches. Each game has a id of register that is named (game) in the database.

My question is: how do I get the user to only bet once on this game? Example: the user bets on match 1 there soon after he can not bet on it again. Each bet has a bet button . I wanted to make this button prevent from being clicked if the user has already bet or appear a script where he says that the user has already bet on this game. Here is the bet code:

bet.php:

<?php
session_start();
include_once("../conn/conexao.php");
if(!empty($_SESSION['email'])){

}else{
   echo"<script language='javascript' type='text/javascript'>alert('Aréa Restrita.');
   window.location.href='/bolao/index.php';</script>";
}

$nome=$_SESSION['nome'];
$email=$_SESSION['email'];
$saldo="SELECT * FROM tb_usuario WHERE email= '$email'";
$exe= mysqli_query($conexao, $saldo);
$linha = mysqli_fetch_array($exe);

$btnApostar = filter_input(INPUT_POST, 'btnApostar', FILTER_SANITIZE_STRING);
if($btnApostar){
   include_once ("../conn/conexao.php");
   $dados = filter_input_array(INPUT_POST, FILTER_DEFAULT);

   $aposta = "INSERT INTO tb_aposta(apostacasa, apostafora, valor, data, usuario, jogo)VALUES(
   '".$dados['apostacasa']."',
   '".$dados['apostafora']."',
   '".$dados['valor']."',
   '".$dados['data']."',
   '".$_SESSION['email']."',
   '".$dados['jogo']."'
   )";
   $r_aposta = mysqli_query($conexao, $aposta) or die (mysqli_error($conexao));
   $verificacao = "SELECT * FROM  tb_jogos WHERE jogo=".$dados['jogo'];
   $exe= mysqli_fetch_array(mysqli_query($conexao, $verificacao));
   $email=$_SESSION['email'];
   $saldo=$linha['saldo'];
   $valor=$_POST['valor'];
   // var_dump($exe);
   if (($valor) > ($saldo)){
      echo
      "<script>
      alert('Voce nao possui saldo para realizar a aposta.')
      window.location = 'apostar.php';
      </script>";
   }else{

      if(($dados['apostacasa'] == $exe['placarcasa']) && ($dados['apostafora'] == $exe['placarfora'])){

         $up = mysqli_query($conexao,"UPDATE tb_usuario SET saldo=saldo+'$valor' WHERE email = '$email' ")or die (mysqli_error($conexao));

         echo "<script> alert('Voce acertou, parabéns')
         window.location.href='apostar.php';
         </script>";

         ;

      }else{ //se estiver errado irá diminuir o valor apostado

         $up = mysqli_query($conexao,"UPDATE tb_usuario SET saldo=saldo-'$valor' WHERE email = '$email' ")or die (mysqli_error($conexao));

         echo "<script> alert('Voce errou, tente novamente')
         window.location.href='apostar.php';
         </script>";
      }

   }

}
?>

I recommend, you create a table called for example: bets_made, with id | user_id | free online games | bet | status

Each click of the bet made by the user, you save in this table, and check if the same user already bet in this game, from that logic, you perform more conditions and checks to make the betting system safer, such as date, ip and etc ... It is at your discretion. In my case I would do it that way, since javascript is not being used.

You just check the betting database on the betting id for example

First consult the database with the user id:

$query = "select * from apostas where id_usuario='$id_usuario'";
$result= $db->query($query); // aqui suas variáveis de conexão
$list= $result->row; // aqui para selecionar um célula

Then create a condition for this, for example:

<?php if($list['id_usuario'] != ''){ 
echo '<button type="submit">Apostar</button>';
}else{
echo 'Ops você ja apostou' OU '<button type="submit" disabled>Apostar</button>';
}

So using the disabled the button becomes inactive, and within the condition it will check if there is a value inside the betting table with the user id.

Fill LineChart (Line Chart) wpf with data from a sql server query How do I get the methods to receive the x and y parameters?

You need to search the bank for the games that the user has already bet and deal with when building the tables.

My suggestion is to change the query line below:

$buscar="SELECT * FROM tb_jogos ORDER BY jogo DESC";

To:

$buscar="SELECT *, a.jogo as id_jogo FROM tb_jogos a LEFT JOIN tb_aposta b ON (a.jogo = b.jogo) GROUP BY id_jogo ORDER BY id_jogo DESC";

In while , add the lines at the beginning:

$desativa_btn = "type='submit'";
if($linha['usuario'] == $_SESSION['email']){
   $desativa_btn = "disabled='disabled' type='button'";
}

and in the button row, add $desativa_btn :

<td><input ".$desativa_btn." class='btn btn-success submit-botao' value='Apostar' name='btnApostar'></td>

The while will look like this:

while($linha = mysql_fetch_array($exe)){
   $desativa_btn = "type='submit'";
   if($linha['usuario'] == $_SESSION['email']){
      $desativa_btn = "disabled='disabled' type='button'";
   }

   echo "<form class='form-group' action='' method='post'>
   <input class='form-control' type='hidden' name='data' id='id_01' readonly>
   <tbody>
   <tr bgcolor='#222222'>
   <td><font color='white'><input type='int' class='form-control' name='jogo' maxlength='1' value=".$linha['id_jogo']." style='text-align: center;' readonly='readonly'></font></td>
   <td><font color='white'></font></td>
   <td><input type='int' class='form-control' name='apostacasa' maxlength='1' value='' style='text-align: center;'></td>
   <td><font color='white'></font></td>
   <td><input type='int' class='form-control' name='apostafora' maxlength='1' value='' style='text-align: center;'></td>
   <td><input type='int' class='form-control' name='valor' maxlength='5' value='' style='text-align: center;'></td>
   <td><input ".$desativa_btn." class='btn btn-success submit-botao' value='Apostar' name='btnApostar'></td>
   </tr>
   </tbody>
   </form>";
}

With these changes, the Bet button should be disabled for bets registered with the bank with% of user%.
