如何在PHP的文本框中显示会话变量的值

Question

in my project I need to take the value of selected link from one page to another page and it should be display in the textbox.

for this i have used session variable code is as below :

in caledar.php

This is not the entire script ... there is one class which generates the calendar code. below is the function.

function getDateLink($day, $month, $year)
        {
            // Only link the first day of every month
            $link = "";
            if ($day)
            {
                $selectedDate = $day.$month.$year;
                var_dump($selectedDate);die;
                //session_register("$selectedDate");
                //session_start();

                if (isset($_GET["selectedDate"]))
                $_SESSION['date'] = $selectedDate;

                //("location:login_sucessful.php");

                $link = "Leave_app.php";
            }
            return $link;
    }

in application.php

<input type="text" id="Editbox1" name="strt_date" value="<?PHP
if(isset($_SESSION['date'])){echo $selectedDate;}?>">

It is not working. also not receiving any error message.

您没有在回显实际的$ _SESSION变量，需要这样做：

<input type="text" id="Editbox1" name="strt_date" value="<?PHP if(isset($_SESSION['date'])){echo $_SESSION['date'];}?>">
