PHP adding characters to jQuery.AJAX posted string

[eluser]Unknown[/eluser]
Couldn't find any answer to this online, or via the search function, so I decided posting it:

I've got a form, like any other, being posted to an AJAX controller within CodeIgniter. The following code is part of a larger form which is being posted.

Code:

<tr>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef1_active" value="1"&gt;&lt;/label></td>
        <td>&lt;input type="text" name="ef1_label" value=""&gt;&lt;/td>
        <td><select name="ef1_clang" class="input-small">'.$optionlist.'</select></td>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef1_required" value="1"&gt;&lt;/label></td>
    </tr>
    <tr>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef2_active" value="1"&gt;&lt;/label></td>
        <td>&lt;input type="text" name="ef2_label" value=""&gt;&lt;/td>
        <td><select name="ef2_clang" class="input-small">'.$optionlist.'</select></td>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef2_required" value="1"&gt;&lt;/label></td>
    </tr>
    <tr>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef3_active" value="1"&gt;&lt;/label></td>
        <td>&lt;input type="text" name="ef3_label" value=""&gt;&lt;/td>
        <td><select name="ef3_clang" class="input-small">'.$optionlist.'</select></td>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef3_required" value="1"&gt;&lt;/label></td>
    </tr>
    <tr>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef4_active" value="1"&gt;&lt;/label></td>
        <td>&lt;input type="text" name="ef4_label" value=""&gt;&lt;/td>
        <td><select name="ef4_clang" class="input-small">'.$optionlist.'</select></td>
        <td><label class="checkbox">&lt;input type="checkbox" name="ef4_required" value="1"&gt;&lt;/label></td>
    </tr>

The form is being serialized, and pushed to the ajax to be saved with this code:

Code:

var data = {
        content : content,
        property : property,
        data_type : dataType,
        form_id : $('#form_id').val()
    };

    
     $.ajax({
        type: 'POST',
        url: url,
        data: data,
        dataType: 'json',
        success: function (result)
        {

            if(result.html == 'deleted')
            {
               [removed].reload();
            }
            else
            {
                $('#newForm').html('');
            }
            
        }
    });

The serialized result of the 'content' variable when console.logged:

firstname=1&firstname_required=1&prefix=1&lastname=1&lastname_required=1&homePhone=1&homePhone_required=1&emailAddress=1&emailAddress_required=1&ef1;_label=&ef1_clang=Code&ef2;_label=&ef2_clang=Code&ef3;_label=&ef3_clang=Code&ef4;_label=&ef4_clang=Code

But then when I echo it out in PHP it looks like this:

firstname=1&firstname_required=1&prefix=1&lastname=1&lastname_required=1&homePhone=1&homePhone_required=1&emailAddress=1&emailAddress_required=1&ef1;_label=&ef1_clang=Code&ef2;_label=&ef2_clang=Code&ef3;_label=&ef3_clang=Code&ef4;_label=&ef4_clang=Code

Notice the `;` added on all the `_label` variables...
Tried renaming the variables, placing it on top of the form etc... Nothing works; PHP keeps adding the `;` on those text fields.

Even stripped the controller down to this:

Code:

public function save_form_content()
    {      
     print_r($_POST['content']); exit;
    }

Anyone got any idea?

Thanks in advance!

It was the $config['global_xss_filtering'], still strange that it only adds characters at certain fields though...
