Jquery Insert Form Data using Ajax serialize() method


In this post we can learn how to insert form data to mysql table by using JQuery Ajax serialize() method with php programming code without page refresh. It generates a text string from whole form data in standard form of URL encoded notation. It can be acts on a jQuery object which has selected different form controls like input tag, textarea tag and select tag. After using this serialize() method whole form data will be converted into an associative array and user can use form data in php script by using post method. After using this method we do not required to define form data one by one. We cannot use this method with input type file. This method works on most of the browser. Here I have describe simple, if you are looking for learn in details, you can go with video which you can find on this post.
