[quote author="pierpads" date="1326913594"]Hello to everyone!
I've got a problem with an anchor containing an image:

echo anchor('controllerPrivato/visualizzaPagina',img($banner_image));

where $banner_image contains the src and the id of the image.
The problem is: I need that when someone clicks on the image, it redirects on a specific page with a certain id_page (I have a separated variable for that id_page).

How can I append the page_id to this anchor? (controllerPrivato/visualizzaPagina) waits for a $_POST variable, is that possible to pass it such a variable by the anchor??

thank you very much for help.

First, please use the [ code][/ code] tags when posting code, it is easier to read.

You will find information about the img() helper here: http://ellislab.com/codeigniter/user-gui...r.html#img

You may add the id_page parameter to the url string in the anchor() helper:

Code:

...
echo anchor( 'controllerPrivato/visualizzaPagina'.'/'.$id_page, img( $banner_image ) );
...

You may then read the $_POST data, perhaps using the uri class library to read the segments:
http://ellislab.com/codeigniter/user-gui...s/uri.html
For instance:

Code:

...
$id_page = $this->uri->segment(3, 0); // returns zero (FALSE) if segment is not found or not passed.
...
