Question

我的会话变量只有在第二次加载页面后才会更改为正确的值。由于第一次加载页面时正确设置了其他会话变量（matchid），因此显示此行为很奇怪。如果（审核编号），则设置不正确的变量，它设置在代码段的底部。

守则

我为长代码段道歉，但我不知道错误在哪里：

if ($stmt = $dbc->prepare("SELECT matchid, user1, user2, user1_accept, 
user2_accept FROM matches WHERE user1_accept = ? or user2_accept = ?   
LIMIT 
1")) {
$stmt->bind_param('ii', $id, $id);  // Bind id to parameter.
$stmt->execute();    // Execute the prepared query.
$stmt->store_result();

 // get variables from result.
$stmt->bind_result($matchid, $user1, $user2, $user1_accept,
 $user2_accept);
$stmt->fetch();
$num_rows = mysqli_stmt_num_rows($stmt);
if ($num_rows == 0){header('Location: /nomatches.php');}    
$_SESSION['matchid'] = $matchid;
}
print_r($_SESSION);

if ($user1 != $id){
echo 'user 1 !=';     
$reviewnumber = 'user2_accept';   
echo $reviewnumber;     
if ($stmt = $dbc->prepare("SELECT aboutme, friend, picture FROM  
userprofile
WHERE id = ? LIMIT 1")) {
$stmt->bind_param('i', $user1);  // Bind id to parameter.
$stmt->execute();    // Execute the prepared query.
$stmt->store_result();

 // get variables from result.
$stmt->bind_result($aboutme, $friend, $picture);
$stmt->fetch(); 
$picture = implode('/', array_map('rawurlencode', explode('/',     
$picture)));
}


if ($stmt = $dbc->prepare("SELECT full_name FROM users WHERE id = ? 
LIMIT 1")) {
$stmt->bind_param('i', $user1);  // Bind id to parameter.
$stmt->execute();    // Execute the prepared query.
$stmt->store_result();

 // get variables from result.
$stmt->bind_result($full_name);
$stmt->fetch(); 
}

}

if ($user2 != $id){
echo 'user 2 !=';
$reviewnumber = 'user1_accept';   
echo $reviewnumber;     
if ($stmt = $dbc->prepare("SELECT aboutme, friend, picture FROM
userprofile WHERE id = ? LIMIT 1")) {
$stmt->bind_param('i', $user2);  // Bind id to parameter.
$stmt->execute();    // Execute the prepared query.
$stmt->store_result();

 // get variables from result.
$stmt->bind_result($aboutme, $friend, $picture);
$stmt->fetch(); 
$picture = implode('/', array_map('rawurlencode', explode('/',
 $picture)));
}


if ($stmt = $dbc->prepare("SELECT full_name FROM users WHERE id = ? 
LIMIT  1")) {
$stmt->bind_param('i', $user2);  // Bind id to parameter.
$stmt->execute();    // Execute the prepared query.
$stmt->store_result();

 // get variables from result.
$stmt->bind_result($full_name);
$stmt->fetch(); 
}


 }

$_SESSION["reviewnumber"] = $reviewnumber;

变量：reviewnumber，在第一页加载时正确回显，这就是为什么我不明白为什么没有正确设置会话变量的原因。

Answer 1

会话值在更改会话值之前打印 - 因此新会话值仅在下一页加载时显示。如果其他人有类似问题，这绝对是一件重要的事情。

会话变量仅在页面刷新后设置
