嘿，我面臨的問題是數據沒有得到存儲在我在mysql數據庫中創建的表中。我創建了4桌旅行，Droute，Wroute，Troute 以前，當我只有兩張桌子旅行和路線我的數據正在表中正確填充，但現在，因爲我希望我的數據按每種旅行模式隔離，所以，現在我我正面臨着這個問題。這是我的代碼。 在此先感謝。我的地圖數據沒有得到存儲在MySQL數據庫使用php

嘿有人請幫助我解決這個問題，我的唯一數據是在旅行桌和Droute表上填充，但Troute和Wroute沒有得到填充。旅行（trip_id，src，dest，路線號碼，旅行模式）以及Droute，Troute和Wroute表格結構對於所有人（route_id，trip_id，distance，duration）都是一樣的 –
