我有一些选择字段和一个会话 ID,我需要将它们即时传递给一个 php 文件,该文件会将它们保存到一个数据库中。
假设我有这个代码:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<?php
// first I declare the session value
$_SESSION["sess_id"] = uniqid($prefix = "", $more_entropy = TRUE);
$sess_id = $_SESSION["sess_id"];
// some rows forward, I have my select fields like this one
echo "<select id='num_1' name='num_1' onchange='set_num_1()'>";
?>
<script>
var num_1_val = "";
var session_id = '<?php echo $sess_id();?>';
function set_num_1() {
num_1_val = document.getElementById('num_1').value;
/* here I need to put the ajax code to send session_id and num_1_val to save_to_db.php */
/* I suppose it's some code like follows: */
$.ajax({
type: "POST",
url: "save_to_db.php",
data: xxxxxxxx, /* ------------- here is where I fail
success: function(){
/* something to do back in case I need */;
}
});
}
如何正确地将 session_id 和 num_1_val 传递给 save_to_db.php?
是否有更安全的模式可以将 $_SESSION["sess_id"] 传递给 save_to_db.php 而不像现在这样使其可见?因为使用var session_id = '<?php echo $sess_id();?>';我使 $sess_id 值在页面脚本中可见。
你能帮帮我吗?谢谢小伙伴。
