On click INSERT INTO mySQL without updating the current page

Question

I am working with PHP and mySQL. On page1.php there will be an image that when the user clicks on it there will be a query that inserts into mysql some data. How can I do this without reloading the page or transferring the user someone else and change the image?

What I did so far is to do this but with reloading the page.

Thanks for your ideas/examples.

Answer 1

It is as simples as executing the post method of jQuery library.

Here is an example that calls a PHP script when clicking any image.

$(document).ready(function() {
    $("img").click(function() {
        $.post("executequery.php");
    });
});

In the "executequery.php" you would need to build the SQL and execute it.

Here is the documentation of the method. http://api.jquery.com/jQuery.post/

使用jquery，将ajax调用添加到php脚本中，该脚本应该能够运行插入脚本并返回成功消息。
