php - Errors getting values from 2 MySQL tables -


i having table relationship. have table adds new procurement items, has 2 columns - line_manager_remark , c_level_remark shows approval status line manager , c level executive.

enter image description here

the values these columns gotten table

enter image description here

now, having issues getting status (definitions) of items. not work.

this have done

select     a.*,     b.*     request_items a,     request_status b     a.line_manager_remark = b.id     ,     a.c_level_remark = b.id     ,     a.request_id = '$id'     ,     state = 'active' 

select     request_items.*,     request_status_line_manager.definition line_manager_status,     request_status_c_level.definition c_level_status,     request_items     inner join request_status request_status_line_manager         on request_items.line_manager_remark = request_status_line_manager.id     inner join request_status request_status_c_level         on request_items.c_level_remark = request_status_c_level.id     request_items.state = 'active'     ,     request_items.request_id = '$id'

i note - if '$id' evidence of php / perl string interpolation stop immediately , use parameterised queries, otherwise query vulnerable sql injection (and assume request_items.request_id int instead of text column too...)

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
