如何将jQuery ajax成功数据转换为PHP变量

Question

I'm sending data to a php page for processing through jQuery and ajax and as result I will get

success: function(data){
mydata = data;
}

my data is an url that looks like mydata = https://myurl.com . Now I want to set mydata to a php variable and use it again inside another function in the main page, means: to set $url = mydata; . How can I do that?

Thanks,

You can do that using Post via a from, GET via a query string or you can use cookie like in this solution

how to assign javascript variable value to php variable

Answer 2

You can send the mydata variable to PHP by calling an XMLHttpRequest() via AJAX .

var ajax = new XMLHttpRequest(); // Create new request
ajax.open("POST", "mainpage.php"); // Open the file where you want to send it with POST
ajax.send("mydata="+mydata); // Send mydata variable to PHP

Then in PHP you can check for the variable mydata

if(isset($_POST['mydata'])){
    // do something
}

Answer 3

PHP scripts execute when you open a file and before everything else. Ajax calls exectue when the Javascript is completely loaded. (After php).

So you cant do it. could you give me more detail about what do you want to do?
