Question

 public function getEmployeeId() {
        if (!isset($_SESSION["email"]) || !isset($_SESSION["passwrd"])) {
            header("Location:index.php");
            // Cannot Access this page without Login.
        }
        if (empty($_POST)){
            $_SESSION['ids'] = "";
            $query = mysqli_query($this->connection, "SELECT MAX(EmployeeId) AS EmployeeId FROM employees") or die("Query execution failed: " . mysqli_error());
            while ($row = $query->fetch_assoc()) {
                // Push the id to the array.
                $_SESSION['ids'] = $row["EmployeeId"];
            }
        }
    }

上面的代码段带来了数据库中最新注册的员工ID。 ------------------------＆GT; --------------------

public function updateSalary(){
        if (!isset($_SESSION["email"]) || !isset($_SESSION["passwrd"])) {
            header("Location:index.php");
            // This code Snippet ensures that in order to access this page Employee needs to be Login.
        }
        $EmployeeID = (isset($_GET['EmployeeId']) ? $_GET['EmployeeId'] : '');
        $query = mysqli_query($this->connection, "SELECT * FROM salary WHERE EmployeeId= '" . $EmployeeID . "'") or die("Query execution failed: " . mysqli_error());
        while ($row = $query->fetch_assoc()){
            // Push the id to the array
            $_SESSION['eids'] = $row["EmployeeId"];
            $_SESSION['salry'] = $row["Salary"];
            if ($_SESSION['ids']) {
            $_SESSION['ids'] = "";
            }
        }

上面的代码片段是我更新每条记录的更新功能。我在上面的html表单中包含了上述功能。

问题是：由于我的插入和更新表单相同，因此if语句中的会话值在文本框中回显，否则即使会话未设置，部分也不起作用如果是部分，我该怎么办？请参阅以下代码

这是值属性：

 <td>
                   <input type="number" name="EmployeeId" placeholder="EmployeeId" value="<?php if (isset($_SESSION["ids"])){echo $id_salaries;}else{echo $emp_id;} ?>" id="EmployeeId" autocomplete="off" class="form-control" readonly>
                </td>

Answer 1

这不是会话未设置NavigationEventArgs.Parameter这是您为会话分配空字符串值。会话未设置应为$_SESSION['ids'] = "";

if else在html的value属性中构造问题
