Are there any security issues I need to worry about jquery-ui-autocomplete working with get array enabled - El Forum - 04-05-2011

Hello all

After several weeks of struggling I have finally managed to get the jquery ui autocomplete widget working and reading data from a mysql database however I have had to enable the get array in ci, do I need to be worried about any security problems.

I am using the following

jquery-1.5.1.js

jquery.ui.core.js
jquery.ui.widget.js
jquery.ui.position.js
jquery.ui.autocomplete.js

I am using jquery ui version 1.8.11
CI 2.0.1 with GET array enabled

As with any online software.

NEVER TRUST USER INPUT!

Hi InsiteFX thanks for the response

I should probably escape the input using

Code:
$keyword = $this->input->get('term');

instead of

Code:
$keyword = $_GET['term'];

I already have CSRF protection enabled, although I did read elsewhere on this forum that some members were having problems with that I also noticed that a lot of the posted code examples had $AJAX{ ... in the js for the view what was that all about?

There is a second parameter to $this->input

Code:
$keyword = $this->input->get('term', TRUE);  // TRUE use the XSS filter

They are putting the Ajax code in their views, I always put my jQuery code into stand alone files jQuery code does not belong in the view only to load it.

If you use files like I do place your scripts at the bottom of the html file just before the closing </body> tag. But load the jQuery and jQuery UI in the head tags.

For now I actually have global XSS filtering enabled and may leave it that way as it doesn't seem to slow the site down much at all (my page load times are below 1 sec after caching so far and actual page execution time is below 0.2 seconds)

    $(function() {

        function log( message ) {

            $( "<div/>" ).text( message ).prependTo( "#log" );

            $( "#log" ).attr( "scrollTop", 0 );

        }

        $( "#town" ).autocomplete({

            source: "&lt;?php echo site_url(); ?&gt;admin/vacancy_admin/location_autocomplete",

            minLength: 2,

            select: function( event, ui ) {

                log( ui.item ?

                    "Selected: " + ui.item.value + ui.item.id :

                    "Nothing selected, input was " + this.value );

            }

        });

    });

//--&gt;

Although I could probably move that as well, I'm not sure, I am still very new with javascript I find it a difficult language to pick up

with the jquery and jquery ui files, I load them dynamically into the header for that page only (it keeps page sizes down) I use a common header and footer throughout the site
