I am experiencing problems trying to do a multitextarea on a form.
I've a PHP view that has various forms, all processed different but in the same file. They all works, I've tested and they works. In forms there are a + icon that let the user add more instances of a <textarea />. This + icon loads via AJAX a new textarea with the same name of the previous textarea (for example, name="example[]"). If I post this, it only gets the first item that is the one that wasn't previously loaded by jQuery. The problem is that the ones loaded dynamically are totally ignored and I don't know why.
My extract of my PHP view:
    <?php echo form_open("projects/view/".$projectid); ?> <!-- This generates a valid <form /> tag -->
        <table>
            <tr>
                <th><?php echo lang("label_conx");?></th>
                <td class="textarea-edit">
                    <textarea class="context" name="CONX[]"><?php echo set_value("CONX[]");?></textarea>
                </td>
                <td class="add"><a id="add-conx" href="#"><?php echo img("img/icons/plus.png");?></a></td>
            </tr>
...
My jQuery code that works fine because the content is displayed and I see in firebug that is the same as the html loaded textarea:
$("a#add-conx").click(function(){
    $("#ajax-loader").fadeIn('normal');
    $("textarea.context:last").after('<textarea class="context" name="CONX[]"></textarea>');
    $("#ajax-loader").fadeOut("normal");
    return false;
});
And when I send the form, I've a in my PHP controller print_r($_POST); and I only get:
Array
(
    [CONX] => Array
        (
            [0] => safdsddasfafsd
        )
    ...
If I put on the PHP view various textareas, this array increases as same of the number of textareas I've created on the HTML view file. I don't understand why this is not working.
When the page is load:

After adding some content dynamically:

This two images shows 4 instances of textarea with the name context[] (that has been changed to CONX[], but fails equal) that are in the view. The second image shows the loaded ones with jQuery and PHP only detected the first 4 that were on the HTML.
Anyone has some idea how I can solve this?
Thank you in advance!
