javascript - 如何在不使用 $_SESSION ["name"] = "<script>document.write(name)</script>"的情况下将 js 变量存储到 php 中；？

Question

我尝试使用 $_SESSION["name"] = "document.write(name)";如果我回应它，​​它就会起作用。但是，如果我将此 SESSION 变量显示到文本框中或使用它来执行 SQL，它会显示 document.write(name)。我怎样才能正确地将它存储到一个 php 变量中？我搜索了一下，很多人说你不能转换它。但肯定有一些地方我可以使用 Javascript 变量(名称)在文本框中显示它或在 SQL 中使用它。

带有变量名的javascript代码。

<script>
    var name;
    $(document).ready(function()
    {
        $('#info tr #name').click(function()
        {
            name = $(this).text();
            alert(name);
            window.location = 'CV.php';
        });
    });
</script>

对于 SQL 我的代码是这样的，

<?php $_SESSION["name"] = "<script>document.write(name)</script>"; 
    echo $_SESSION["name"];
    $connect = mysqli_connect("localhost", "root", "","test1");
    $sql = "SELECT Name, Number, Expertise, Status, Remarks FROM particulars WHERE Name ='". $_SESSION["name"]."'";

    $result = mysqli_query($connect, $sql);

    while($row= mysqli_fetch_array($result))
    {
        $name = $row['Name'];
        $number =$row['Number'];
        $Expertise =$row['Expertise'];
        $status =$row['Status'];
        $remarks =$row['Remarks'];
    }
?>

下面是我的代码，试图将我存储在 session 中的变量显示到文本框中。

<input type='text' value='" .htmlspecialchars($_SESSION['name']) . "'/>

<script>
    var name;
    $(document).ready(function()
    {
    $('#info tr #name').click(function()
    {

        name = $(this).text();
        alert(name);
        window.location = 'CV.php?name=' + name; // send in link

    });
    });
    </script>

CV.PHP 内部

if(isset($_GET['name']))
{
    $name = $_GET['name']; // Get it from URL
    $_SESSION["name"] = $name; 
}
else
{
    $name = $_SESSION['name']; // Get it from session
}
$connect = mysqli_connect("localhost", "root", "","test1");
$sql = "SELECT Name, Number, Expertise, Status, Remarks FROM particulars WHERE Name ='". $_SESSION["name"]."'";

$result = mysqli_query($connect, $sql);

while($row= mysqli_fetch_array($result))
{
   $name = $row['Name'];
   $number =$row['Number'];
   $Expertise =$row['Expertise'];
   $status =$row['Status'];
   $remarks =$row['Remarks'];
} ?>

在输入框中显示:

    <input type='text' value='" .$name . "'/> // echo value as string
    <input type='text' value='" .$_SESSION['name']. "'/> // if it's a page that is not CV.php
