Ajax post to php on same page not working
提问by Khanh TO
I am trying to pass a var from jQuery to PHP.
我试图将一个 var 从 jQuery 传递到 PHP。
After researching I found the most common suggestion was to do this with Postwith Ajax and store the post var using PHP.
经过研究，我发现最常见的建议是Post使用 Ajax执行此操作并使用 PHP 存储 post var。
My PHP skills are pretty good but I can't say the same about my JavaScript skills.
我的 PHP 技能非常好，但我不能说我的 JavaScript 技能相同。
This is what I am doing but does not seem to work at all:
这就是我正在做的，但似乎根本不起作用：
// jquery libray included etc etc
<script>
$.ajax({
type: "POST",
url: "http://currentpage.com",
data: "var=value",
dataType: string
});
</script>
</head>
<body>
<?php
if($_REQUEST["var"] == "value") {
echo "var passed and stored";
}
?>
