Can someone explain what this code is for?

In SMF 2.0 RC4,

Themes\Default\MessageIndex.template.php

Code Select Expand

// Finish off the form - again.
if (!empty($context['can_quick_mod']) && $options['display_quick_mod'] == 1 && !empty($context['topics']))
echo '
<input type="hidden" name="' . $context['session_var'] . '" value="' . $context['session_id'] . '" />

Why the <input> values are being echoed that too as hidden?
I just want to know what is the significance of this code?

I believe that is for session checking, so it's a security measure in the quick moderating options, not actually completely sure about that - at least not without seeing the complete code around it...

But I think checking is done in if loop and we are just echoing session i.e not checking it (just my opinion).

You have to put the session into the form so when the form is submitted (e.g. when using checkboxes) the session identifier will be able to be checked on receipt of the form.

Hmm, explains to nice extent, thank you .
