passing variable in URL - El Forum - 06-22-2009

Hi,

I'm sure this is very stupid question, but I kind of shamefully stuck here.

I need to insert a variable $city into a Anchor tag and I getting all kind of errors.

here is the string

Code:
&lt;?=anchor('index.php?/display_add/details', '<img src="images/find.gif" border="0" alt="">');?&gt;

I need variable $city to be passed as a URI segment after /details...

Thanks

Alex

this depends on how you get the data
if you use

Code:
$this->uri->segment(n);

Then something like this

Code:
&lt;?=anchor('index.php?/display_add/details/'.$city, '<img src="images/find.gif" border="0" alt="">');?&gt;

If like me you prefere to make an array of segments using

Code:
$this->uri->uri_to_assoc(n);

then you would use something like

Code:
&lt;?=anchor('index.php?/display_add/details/city/'.$city, '<img src="images/find.gif" border="0" alt="">');?&gt;

then

Code:
$segments = $this->uri->uri_to_assoc(3);

would produce

Code:
$segments[array]

(

  'city'=>xyz,

)

I prefer this because the segments can then be added in any order of matching pairs and the url still works

Assuming you have the value in the variable $city, then this should pass that value back as segment 5. Don't forget the slash after the function name "details".

Code:
&lt;?=anchor('index.php?/display_add/details/'.$city, '<img src="images/find.gif" border="0" alt="">');?&gt;
