我試圖通過從我的數據庫獲取緯度和經度來顯示點,而查詢是(SELECT * FROM trackEmployee
)它正在檢索 數據並在地圖上顯示它(Y)將變量從php標記傳遞給同一頁中的其他標記
但是,當我試圖通過獲取POST數據來設定條件WHERE groupEmail ='$mail' AND date= '$date'
它不工作
如果我直接值傳遞給的條件下,它的工作原理(Y)
問題這裏是從上面的php標籤獲取數據到下一個包含查詢的php標籤。

你知道你在「$郵件」和「$日期」空白?在查詢中使用它們之前,先嚐試檢查$ mail和$ date的值,以此來提高安全性;-) – Stefan
'mysql'調用已被正式棄用,請切換到'mysqli'或'pdo' –
您有空白您的查詢參數。刪除'$ mail'的前導和尾部空格以及尾部空格替換'$ date' –
