note 38425 added to function.addslashes

When i got bored to write $_POST[foo] to retrieve variables from previous pages, i wrote this. Since i've been thinking of including it in each page, it includes a control to avoid re-encoding of previously encoded variables by renaming them (example: at first encoding, the single quote becomes \' but without that control in the next page it would became \\' and so on). As you can see below, for sure i'm not the greatest coder on earth: any further suggestion or correction is absolutely welcome. function enc($field) { $field = trim($field); $field = str_replace(" ", "_", $field); $field = addslashes($field); return $field; } function enc_hidden($field) { $field = str_replace("'", "\'", $field); return $field; } foreach($_POST as $i => $value) { if(substr($i, 0, 2) != "v_") { if(substr($i, 0, 4) == "hid_") { $i = str_replace("hid_", "", $i); $v_{$i} = enc_hidden($value); } else { $v_{$i} = enc($value); } } } ---- Manual Page -- http://www.php.net/manual/en/function.addslashes.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+38425 Delete -- http://master.php.net/manage/user-notes.php?action=delete+38425&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+38425&report=yes Search -- http://master.php.net/manage/user-notes.php
