|
|
Download from here.. Target audience: Advanced users.
Here, the term magical - means searching an index within POST, GET, SESSION, COOKIE. An usage examle would be:
Code: | {html_options options=$subdomains selected='subdomain_id'|magical} |
Here, it searches for any presence in post, get, session, cookie data for subdomain_id index. This saves a little time in coding, as you do not need to write anything in your php code to know what was your selected subdomain id.
Say, if you set $_SESSION['subdomain_id'] once, it works forever, anywhere you are in. The above example is a droop-down list of subdomains, and by default, selects the alredy chosen subdoain_id.
You might have passed that subdomain id in POST or GET flags and get a priority. For example, loading the page: edit-subdomains.php?subdomain_id=78 would magically use this id: 78, disregarding whaver was in the SESSION earlier. |
