用Ajax执行php文件

When I click on "Register Now" Button, I want to execute 'input.php' in which I have code to insert my data to the database and show a success message. I don't want to leave current page.

<input type="button" id="confirm" value="Register Now" class="button">

<script type="text/javascript">
$(document).ready(function() {
  $("#confirm").click(function() {
    <?php
    include 'input.php';
    ?>
    alert ("data Added successfully.");
  });
});
</script>

My code is giving me "data Added successfully" message but PHP file hasn't executed and no data is added to the database. All necessary data is in session variables.

To execute a Php script from javascript, you have to use Ajax.

the following code :

$("#confirm").click(function() {
    <?php
    include 'input.php';
    ?>
    alert ("data Added successfully.");
  });

will not work

Try this:

<input type="button" id="confirm" value="Register Now" class="button">    
<script type="text/javascript">
$(document).ready(function() {
  $("#confirm").click(function() {
    $.get('input.php').
    success(function(){
       alert ("data Added successfully.");
    });
  });
});
</script>

Suggest you try something like the below. You shouldn't be trying to execute PHP inside of a jQuery script. Do an AJAX call and pass the data through and process it in the PHP rather than relying on the session variables. For example:

<script type="text/javascript">
    $(document).ready(function () {
        $("#confirm").click(function () {
            $.ajax({
                    type: "POST",
                    url: "index.php",
                    data: {
                        firstname: "Bob",
                        lastname: "Jones"
                    }
                })
                .done(function (msg) {
                    alert("Data Saved: " + msg);
                });
        });
    });
</script>

Where firstname, lastname would be your normal session data.

You can learn more about the jQuery.ajax() function in the jQuery API Documentation.

You need to use AJAX. Ajax is the concept of calling php files from javascript from inside the page. You then get the php page output in a variable and you can choose wether you will display it or not. An example of this technology is the show more posts of Facebook. This can be easily done with jQuery.

$.post( PHP_FILE, { field1: 'value', field2: 'value'}).done(function( data ) 
{alert("this function will be run when the request is over and the variable data 
will have the output : " + data);});

I'm not quite sure what you've tried to do there. Anyway here's a snippet of js that should do for you (I'm pretty sure in the new jQuery release there's a better way to do this though):

$.ajax({ 
    url: "input.php",
    success: 
        function(data)
        {
            // here, for example, you load the data received from input.php into
            // an html element with id #content and show an alert message
            $("#content").html(data);
            alert("Success")
        }
});

you can do this by ajax post method..

 $.ready(function(){
 $("#confirm").click(function() {
 $.ajax({
 type: "POST",
 url: "give url to the input.php file ",
 data:,
 success:function(data)
 {
  alert('data');// data is the return value from input.php
  }
  });
  });

});
