나는 거의 2 일 동안 머리를 부러 뜨 렸고 해결책을 찾지 못했습니다.레일 3. 인보이스의 광고 항목 및 광고 항목 이름에서 표를 작성하는 방법은 어떻게 다릅니 까?
송장 번호, 총액, 지불 금액 및 잔액이있는 송장 목록이있는 테이블이 있습니다. 잘 작동합니다. 이제 모든 광고 항목을 표에 추가해야합니다.
invoices 테이블에는 of_lax, air_rate_customer, pss라는 열이 있으므로 쉽게 사용할 수 있으므로 값이 있는지 확인해야합니다.
까다로운 부분가 fcl_variable_cost_1_amount 속성에 대해, 난 (fcl_variable_cost_1_amount, fcl_variable_cost_2_amount 등) 사람들의 팔을 얻었다.
fcl_variable_cost_1_amount에는 해당하는 fcl_variable_cost_1_charge_id가 있으며 요금 테이블에 연결됩니다.
하나의 인보이스에서 fcl_variable_cost_1_id는 34이며 금액은 $ 100입니다 (ID 34는 "ISF"에 해당).
다른 송장에서 fcl_variable_cost_1_id는 12 일 수 있으며 $ 50 (ID 12는 "시험 수수료"에 해당)입니다.
변수 이름 광고 항목을 어떻게해야 열에 표시 할 수 있습니까?
이것은 내 코드입니다. 스크린 샷도 있습니다. 경우 사람의 미래 참고로
