Songs module – modifications in the HTML• <form action='index.php?action=EDIT&id=[song_id]' method='POST'>

<form action='[page_code]?action=EDIT&id=[song_id]' method='POST'>

• Instead of http://localhost/dir/ index.php?action=EDIT&id=42 , the form will submit to http://localhost/dir/songs?action=EDIT&id=42

• We should change the same references in the PHP file too

V 1.0

Songs module – modifications in the PHP• $page should always contain the page code• Move import(), designer_replace(),

create_select_from_array(), addlink() to general.php• (Add isloggedin(), draw_menu() to general.php)

• Check for CMSMOD comments in the html and php files– Changed every addlink(“index.php?action=xxx”) code

to addlink(“{$page}?action=xxx”)– Changed every header(“location: index.php”) code to

header(“location: {$page}”)– $module_html="html/song_form.html";
