Uri Class problem

[eluser]Ngulo[/eluser]
hi all i have a controller (downloads.php) with this function (templates) after the main index():

Code:

function templates()
        {
          
             $tab_from_uri=$this->uri->segment(3);
                switch($tab_form_uri)
                {
                    case "1":
                        $tab = "tab1";
                    break;
                    case "2":
                        $tab = "tab2";
                    break;
                    case "3":
                        $tab ="tab3";
                    break;
                }
               $data['asd']=$this->db->order_by("data_templx","asc")->get(''.$tab);
               $this->load->view('downloads_view',$data);
            
        }

my links are

Code:

anchor('downloads/templates','List')
so they took me rightly to /index.php/downloads/templates/3 ...as i want

but,when i click the link ,loading the view,i take this error:

Code:

Message: Undefined variable: tab_form_uri

i can't find any error,i've prooved also changing uri->segment(3) to uri->segment(4)......this is not the problem i guess

any suggestions?

It probably also tells you where PHP has detected this undefined variable? Because that one isn't used in your code segment, you use $tab_from_uri, and not $tab_form_uri...

oh my god!!!!!!!!!!!!! sorry!!!!!!! ahahahah what i stupid i am!!!

really sorry ,sometimes i would like to kill myself eheheh

sorry for another question

when i take

$data['data_from_uri']=$this->uri->segment();

and insert this into a db, is this prep from the helper or i need to escape it after:
$data['data_from_uri']=mysql_real_escape_string($this->uri->segment()); (for example)

??

really thanks man

[eluser]WanWizard[/eluser]
Depends on how you insert it. If you use Active Record everything will be escaped for you, unless you disable it.
The manual (have you read it? ) is very clear about this.

[eluser]Ngulo[/eluser]
yes man,i understand ,and i always use active records to running queries, but i don't mind what you mean with disable escape on active record class? how do you disable escapes in this?
i can't find any suggest on active records guide on this argument ... i guess i'm blind

and what about uri-segment()? is this automaticly escaped or not?



really thanks again

[eluser]WanWizard[/eluser]
As per the manual:

If you are using a database that CodeIgniter escapes queries for, you can prevent escaping content by passing an optional third argument, and setting it to FALSE.

uri->segment() is a retrieval function, there is nothing to escape.

[eluser]Ngulo[/eluser]
pardon me Wan i'm new on PHP imn general and on CI's to

so if i don't specify any third parameter in active class the data are escaped automaticly?right?

thanks again
