Loading dynamic external form with jquery

Question

I hope someone could help me.

When i load an external php that generates a set of fields, i have no problems, but then i send the generated form, i can not access the vars.

There is the code i user:

For load the external file:

      $.ajax({

    type: "POST",
    url: "product-insert.php",
    contentType: "application/x-www-form-urlencoded",
    global: true,
    processData:true,
    dataType: 'html',
    data: {num_filas: $("#num_filas").val()},

    success: function(html){
             $("#destino").html(html);
             alert(html);
             str = $("ofertas").serialize();
    },

    error: function(){
    },

    complete: function(){
    }
});


  <form action="ofertas.php" method="post" enctype="multipart/form-data" name="form-ofertas" id="ofertas" >

  <div id="destino"></div>

The file loaded have this code:

echo '<input name="campo" type="hidden" value="valor" />';

and the php file that receive the form have this code:

die("campo: ".$_REQUEST['campo']);

I really will appreciate a lot the help.

Thnx in advance.

Need more complete data. Where are you loading it? Where are you posting it to? If done correctly, it should work. — Kerry Jones, Jun 29 '10 at 21:47
@Kerry "if done correctly, it should work" is my quote of the day ;) @Sauron what do you mean by "cannot access the vars"? When? — Pekka, Jun 29 '10 at 21:52
@Pekka i mean that i can not receive the vars of the dynamic loaded form, when i click submit the form. Thnx to all for your help :) — SauronZ, Jun 29 '10 at 22:00
@SauronZ - Are you sure they're getting loaded? if you alert the html in the `sucess`, what are you seeing? — Nick Craver, Jun 29 '10 at 22:07
@Nick Craver. Here is the result code, so is getting loaded fine. — SauronZ, Jun 29 '10 at 22:15
@SauronZ - Did you add those code tags or is that in the response? — Nick Craver, Jun 29 '10 at 22:18
@Nick Craver - Sorry, i put them to try formatting the code. — SauronZ, Jun 29 '10 at 22:21
@SauronZ - I added an answer below for what seems to be your issue, and for future reference: [How to format code in comments](http://meta.stackexchange.com/questions/24793/how-to-use-formatting-in-comments) :) — Nick Craver, Jun 29 '10 at 22:32
@SauronZ - Your comment says `get` your question says `post`....which method are you actually using? — Nick Craver, Jun 29 '10 at 22:38
@Nick Craver - Sorry for the confusion. Im using post., but i have tried with get and nothing. — SauronZ, Jun 29 '10 at 22:40
Can you confirm using firebug that the form elements are actually being included in the form? — Pekka, Jun 29 '10 at 22:53
Yes, elements are inluded, but i see in firebug that when sending the form, none of the loaded html content is sent with the subit. — SauronZ, Jun 29 '10 at 23:17

Based upon your comment, you're checking for $_POST['campo'] despite the fact that your <form> tag's method is a GET request. You should instead check the value of $_GET['campo'] (or $_REQUEST['campo']).

i've tried, but still not working :( I think problem is that the values of the form dinamically loaded are not sent when click the submit button. Maybe if i send the form using jquery will work? Thnx in advance. – SauronZ Jun 29 '10 at 22:39
Do you have a `` tag? You didn't include it in your question if you do. – Matt Huggins Jun 29 '10 at 23:27

I'm guessing partially off comments here, your form looks like this:

<form action="ofertas.php" method="get" enctype="multipart/form-data" 
 name="form-ofertas" id="ofertas"> 
  <div id="destino"></div> 
</form>

Your method is GET, which won't give you what you're after if you're looking for the values in the POST collection, which $_POST does. Just change the method on your form to method="post" to get this working correctly, otherwise use $_GET on the PHP side, if a GET is what you're actually after.

For a good discussion of GET vs POST, take a look here:
When do you use POST and when do you use GET?

@Nick Craver I have updated the code, but still not working. The mistake of POST and GET was due to so many changes :) – SauronZ Jun 29 '10 at 22:37
@SauronZ - now you have 2 `success` functions defined...need that not to be the case, remove the first and put the `alert()` in the second, what's the result then? – Nick Craver Jun 29 '10 at 22:40
@Nick Craver - Removed in code and in example, but still the same.I really don't know what can be happening :( – SauronZ Jun 29 '10 at 22:48
@SauronZ - I don't know what's run from the info provided...any chance there's a page I can hit? – Nick Craver Jun 29 '10 at 22:52
@Nick Craver- http://ulzama.es/admin/ofertas.phpn=1 - User/pass: Nick - Press the second Radio button and continue. Then you have the form. Simply enter 2 in the last field and click Añadir productos, it will load the external field. Really thnx for your patience – SauronZ Jun 29 '10 at 22:56
@SauronZ - I had to run for dinner, can't login now though, let me know if you can re-enable it. – Nick Craver Jun 30 '10 at 00:27
