Question

i know how to post data using javascript but im trying to work out how i can retrieve the last inserted row in a mysql table.

So i can use it in my success result.

Below is what i have so far but all it does is create the entry , i really want to direct the user to a page where they can now edit their new entry without having them click a button to go there first.

The code below has not got the part i really need, i just put it up so you can see my structure of what i am doing.

$("#CREATEDOCUMENT").click(function() {

var txt = $.ajax({
url: 'create_doc_entry.php',
async: true, 
type:'POST',
data:({
usr_id:$('input#usr_id').val(),
}) 

}).success;

$('.pleasewait').fadeIn('slow');    

setTimeout(function(){window.location="index.php?v=editdoc&id="+id;}, 2000);

}); 

As you can see from the above in the window.location url i have +id

I would really love that +id to be my last inserted id which i grab from the create_doc_entry.php file if you know what i mean.

Thanks in advance

First you will need to modify create_doc_entry.php so that it prints the last inserted ID after the INSERT.

Then you probably should add the success setting in your ajax request, like this:

var txt = $.ajax({
    url: 'create_doc_entry.php',
    async: true, 
    type:'POST',
    data:({
        usr_id:$('input#usr_id').val(),
    }),
    success: function( data ) { alert(data); }
});

So you can parse or do whatever you want with data in the success function.
