anchor with image

[eluser]pierpads[/eluser]
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.

Code:

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

Like that?

You could get your controller to look for the post var, if it's not found, look for a uri segment with an int and use THAT as the var you want.

Hello, thanks for reply... I already tried that solution out, but this generates something like
"...visualizzaPagina4" ( 4 is just as example ). I need to pass the variable itself, so that I can retrieve it from the controller ( something like $var=$this->input->post('id_page') ).

Thank you again.

sorry I didn't read the whole post. I'll try it looking for the segment, thank you very much.

How about a hidden form input field?

Code:

if ($this->input->post('id_page') == '') {
    $id_page = $this->uri->segment(3);
} else {
    $id_page = $this->input->post('id_page');
}

Something like this should work...

But clicking a link doesn't submit the form...

[EDIT] in the time it took to write this, you have several other replies, so this may be irrelevant...

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.
...

Thank you very much , it works perfectly!! I am integrating nivo slider to a web site and I couldn't get solution.
I am sorry for the code tag, it was my first topic here to get help.
I'll sure use it the next time.
