下面我有一行代码,它说明了用户当前在总会话数中的哪个会话。
<h1>CREATING QUESTIONS AND ANSWERS: SESSION (AAA) <?php echo $sessionMinus ?> OF <?php echo $_SESSION['initial_count'] ?></h1>
因此,例如,该行可以读取:
CREATING QUESTIONS AND ANSWERS: SESSION (AAA) 3 OF 3
现在我遇到的问题是,假设我想要 3 个会话,它应该是这样的:
第一次用户打开页面:CREATING QUESTIONS AND ANSWERS: SESSION (AAA) 1 OF 3
但相反,它是这样读的:CREATING QUESTIONS AND ANSWERS: SESSION (AAA) 3 OF 3
如果假设我想要 7 个会话,则相同,对于第一个会话,它应该是:CREATING QUESTIONS AND ANSWERS: SESSION (AAA) 1 OF 7
但它的读取方式是这样的:CREATING QUESTIONS AND ANSWERS: SESSION (AAA) 7 OF 7.
所以我的问题是,我怎样才能让第一个会话等于 1...
以下是当前代码:
if(isset($_POST['sessionNum'])){
//Declare my counter for the first time
$_SESSION['initial_count'] = $_POST['sessionNum'];
$_SESSION['sessionNum'] = $_POST['sessionNum'];
}
if (!isset($_SESSION['sessionCount'])) {
$_SESSION['sessionCount'] = 1;
}
else if ($_SESSION['sessionCount'] < $_SESSION['sessionNum']) {
++$_SESSION['sessionCount'];
}
$sessionMinus = $_SESSION['sessionCount'];
更新:
以下是之前的尝试,但它一直说 2 OF 4 或 2 OF 5 或 2 OF 2 等,但没有奏效:
if(isset($_POST['sessionNum'])){
//Declare my counter for the first time
$_SESSION['initial_count'] = $_POST['sessionNum'];
$_SESSION['sessionNum'] = $_POST['sessionNum'];
$_SESSION['sessionCount'] = 0;
}
else if ($_SESSION['sessionCount'] < $_SESSION['sessionNum']) {
$_SESSION['sessionCount']++;
}
$sessionMinus = $_SESSION['sessionCount'];
