In reply to earlier comment, "switch"- I found this to be one of the best ways to interpret 'actions'. Simply create a new instance of Handler_action before including any content source files. This is a highly stripped version of the class. The real one I created handles (and secures) input for $_GET and $_POST, creates a 'permission' array that only allows certain actions to be called by non-admins, and creates handy little diagnostic messages that can be displayed upon redirecting. On that note, the beauty in this class really shines in the simple redirect. You wont be left with ugly URLs like, "http://www.domain.com/path/to/script.php?action=blah&var1=123". Rather, you will be left with something like "http://www.domain.com/path/to/script.php"- helps protect some of the site by not showing any vulnerabilities in URLs. Also, this class keeps all actions organized neatly by directly passing $_GET vars to the actions through function parameters. <?php class Handler_action { function __construct( ){ //Add code here to secure attacks through $_GET or use $_POST $action = $_GET["action"]; //$actions_index conventions: //'action_name' => array( 'arg1', 'arg2', 'etc', ['/redirect/to/path' | NULL ] ) $actions_index = array( 'create' => array( $_GET['newVar1'], $_GET['newVar2'], '/home.php' ), 'edit' => array( $_GET['id'], $_GET['otherVar'], '/home.php' ), 'delete' => array( $_GET['id'], '/other_script.php' ) ); if( $action && array_key_exists( $action, $actions_index ) ){ $redirect_path = array_pop( $actions_index[$action] ); call_user_func_array( array( &$this, $action ), $actions_index[$action] ); if( $redirect_path ) header( "Location: http://www.domain.com{$redirect_path}" ); } } //being defining actions now function create( $new_var1, $new_var2 ){ //code... } function edit( $id, $other_var ){ //code... } function delete( $id ){ //code... } } ?> ---- Server IP: 216.194.113.175 Probable Submitter: 24.94.237.207 ---- Manual Page -- http://www.php.net/manual/en/control-structures.switch.php Edit -- https://master.php.net/note/edit/71457 Del: integrated -- https://master.php.net/note/delete/71457/integrated Del: useless -- https://master.php.net/note/delete/71457/useless Del: bad code -- https://master.php.net/note/delete/71457/bad+code Del: spam -- https://master.php.net/note/delete/71457/spam Del: non-english -- https://master.php.net/note/delete/71457/non-english Del: in docs -- https://master.php.net/note/delete/71457/in+docs Del: other reasons-- https://master.php.net/note/delete/71457 Reject -- https://master.php.net/note/reject/71457 Search -- https://master.php.net/manage/user-notes.php
