2. [code] warehouse receiving of the security card

3. [code] BCC card image generation

4. [code] security card verification

Public function test1 ($ uid) {$ this-> load-> model ('admin/m_users'); $ user = $ this-> m_users-> sel ($ uid ); // post submitted to verify if ($ this-> is_post () {$ codes = $ this-> m_mibao-> get_codes_by_uid ($ uid ); $ codes = unserialize ($ codes); $ is_true = true; foreach ($ _ SESSION ['mibao'] ['Keys '] as $ key) {if ($ codes [$ key]! =_ _ POST ['values'] [$ key]) {$ is_true = false ;}} if ($ is_true) {die ('true ');} else {die ('error') ;}} else {// rendering view $ info = $ this-> m_mibao-> get_by_uid ($ uid); $ data = array (); $ data ['Keys '] = $ this-> m_mibao-> get_rand_keys ($ info ['letter']); $ _ SESSION ['mibao'] ['Keys '] = $ data ['Keys']; $ data ['uid'] = $ uid; $ this-> load-> view ('test1', $ data );}
