  2. Hello I just tried it on my website but it came out with an error saying : Method Not Allowed
    The requested method POST is not allowed for the following URL : /file/myform.html

    I put in the file of course the "join.php" Did I forget something else ?

    ReplyDelete
  3. Wrong:
    url: "/file/join.php"

    Write:
    url: "http://domain.com/file/join.php"

  4. There are some excellent jQuery plugins for this.

  5. hi. why dont use Jquery form Plugin?

    ReplyDelete
  6. @Srinivas : me again (2d anonymous!) Thanks for the tip (url: "http://domain.com/file/join.php") but I actually had it done this way too with the complete url..

    What about the SQL query ?

  7. isn't this better.

    Mootools:
    $('myForm').addEvent('submit', function(e) {

    e.stop();
    this.set('send', {onComplete: function(response){}});
    //send the normal form..
    this.send();
    });

  8. @nocturnal, You can do that with jQuery also. Infact, with jQuery 1.3, you can now do live events. So you can watch for a form submit whether the form is on the page yet or not. Only problem is that it isn't supported in early browsers (think IE5.5).

  12. Hello, I did link with the plug-in, and I am having the same result as Ahmed. I can get the success indicator to show on the screen, but the database query is never run. I am sure I am using the right path to my join.php (http://test/intranet/join.php), but I don't understand why it doesn't execute the query.

  14. I've figured out a large part of my trouble, which was my data string (no ampersand in front of one field name, which caused the WHERE clause to return false).

    I can now execute the query IF I have only one form on the page, but it doesn't seem to work with multiple forms. I have my forms named the same as the primary index of the query table, and I am using a hidden field to carry that value to the ".submit" function.

  22. Is it safe to send the password via AJAX to a PHP script? For instance if you check Firebug you can see the password string being send to the server.

  23. Hello Sir.... This was what i was exactly trying to achieve. I had a form inside jqueryUI tabs but i was facing problems while posting the form... Your method is really much simple and i am using it on my form.. Thanks for the great script...

    ReplyDelete
  24. One main problem I am having with this is updating checkboxes. It is no problem submitting when you FIRST check a box. But what if you want to uncheck a box. Every time I un check a box it does not carry a null value over to the database. Any ideas would be appreciated.

    ReplyDelete
  25. Ignore the last message. I have resolved that issue. Now the issue is submitting on one form when I have multiple forms that contain the same inputs. Whenever trying to update one of the lower forms on the page, it always defaults to the values of the first form on the page. Is there any way to give the script a form id or name to get it's values from?

    Thanks Again,
    Derek

  28. Hi,
    I just tried that and everything works fine until I send the data to the php script.
    The $_POST['someVariable'] is always empty.
    I tried sending the data with the serialize method and I alerted out the string to make sure that it wasn't empty which it wasn't and then I wrote out the string like you did in this example and the value is always empty in the php script. I made sure that I don't have spelling mistakes in the names of the variables. What could it be? Thanks.

  31. To clear textfields after submitting:

    $('#name').val('');
    $('#username').val('');
    $('#password').val('');


    add the above lines after

    $.ajax({
    type: "POST",
    url: "join.php",
    data: dataString,
    success: function(){
    $('.success').fadeIn(200).show();
    $('.error').fadeOut(200).hide();

    in Java Script code

  33. Hello I am curious to know what the solution to using multiple forms on one page, each with their own submit and unique IDs.

    I am making an image approval script, it reads all images in a directory and creates forms for each. I am unable to use onSubmit="action()" using ajax/jquery with multiple forms on the page.

    Can you please give me a hand with this? My email is prodigymix at gmail dot com

    Thanks!

  34. Hi.

    I´m trying to make a facebook connect submit form where ppl can update their status from my homepage.

    When I change this:
    url: "join.php",
    to
    url: "https://graph.facebook.com/<%=fbUid%>/feed",

    (something I must do)

    the form stops working. the whole page refreshes when I submit and nothing gets posted and theres no message in the DIV...

    if i try to post to a local file the form and script works as it should.
    ex.
    url: "test.asp",
    or
    url: "http://www.mydomain.com/test.asp",

    is this script not working with external url´s?

    ReplyDelete
  35. Thank you so much for this script!

    I just need to know what code to write in the join.php so I can receive what was filled in the form in my e-mail.

    The simple the better, please.

    Thank you again!

  41. Hi if I were to have two forms with the same class names for each input in each form how would I make it so that only the data from the form I submitted gets sent to the php script and not just the contents of the first form? I know it has something to do with $(this) but I can't figure it out.
    The forms are outputted through php and there's no definite amount of them. I guess it's something similar to the way facebook commenting works on everyones main feed.
    Hopefully someone can help me!

    ReplyDelete
  42. Hi, good tutorial. It works fine for me except that whenever the form error submission (in case of invalid data) is followed by a valid submission, the SQL is processed twice generating duplicate entries in database. Any idea how to control this behaviour?

  61. @Shiva Surya

    I did this, and it works
    [code] ...
    $.ajax({
    type: "POST",
    url: "join.php",
    data: dataString,
    success: function(){
    $('.success').fadeIn(200).show();
    $('.error').fadeOut(200).hide();

    $('[name="inputName"]').val(''); <-- this part cleans the input

    }
    ...[code]

  62. Brilliant! Just what I needed. I'm a long-time PHP coder but new to AJAX and needed a very simplified example to work through the code and understand it. Other tutorials used more code than was necessary so were more difficult to understand but yours was perfect. Cheers :)
