我想用foreach語句將xml文件加載到我的MYSQL數據庫中。它由於某種原因成功地在XML文件中循環,但似乎只有通過循環的第一次實際發送到數據庫。MYSQL PHP Foreach語句只提交第一個插入語句

<?xml version="1.0" encoding="utf-8" ?>

    <!-- Table Alarcos --> 
    <Alarcos> 
     <Alarcos_ID>12</Alarcos_ID> 
     <Device_ID>16cf10d0-5154-444e-96ad-46e913ac9761</Device_ID>

這是我用來處理XML

<?php 
    $xml = simplexml_load_file("test.xml") or die("Error: Cannot create object"); 

    $createAlarcos = $conn->prepare("INSERT INTO Alarcos_Data (alarcos_id, device_id, sender, receiver, message, alarcos_timestamp) VALUES (?,?,?,?,?,?)"); 

    $createAlarcos->bind_param("isssss",$alarcos_id, $device_id, $sender, $receiver, $message, $alarcos_timestamp); 

    foreach($xml->children() as $Alarcos) { 

     $alarcos_id = $Alarcos->Alarcos_ID; 
     $device_id = $Alarcos->Device_ID; 
     $sender = $Alarcos->Sender; 
     $receiver = $Alarcos->Receiver; 
     $message = $Alarcos->Message; 
     $alarcos_timestamp = $Alarcos->Timestamp; 

     $createAlarcos->execute(); 

    } 

    $createAlarcos->close(); 
    ?>

這看起來不錯;我假設'$ conn'是mysqli而不是PDO?任何錯誤?你有沒有添加調試,以確保你實際上處理XML中的多個孩子? – miken32

$ conn是mysqli。我相信它正在處理不止一個孩子。當我在foreach中回顯出alarcos_id時,它給出了它的兩個實例。 – kirie

我發現在某些情況下綁定到不存在的變量可能會造成麻煩。我通常在綁定它們之前將變量聲明爲空。 – miken32

你必須在這兩個XML元素相同ID的PHP代碼。可能alarcos_id是數據庫表中的主鍵,因此它不會被覆蓋。這是檢查錯誤結果的好理由;​​可能返回false。

... 
if (!$createAlarcos->execute()) { 
    foreach ($createAlarcos->error_list as $err) { 
     echo "Error $err[errno]: $err[error]<br/>\n"; 
    } 
}

執行查詢的輸出幫助我發現我的db表的主鍵不是auto_incrememted。所以它一直試圖提交我的插入與ID爲'0'。非常感謝。 – kirie
