正在上傳文件，但INSERT不會將位置添加到數據庫中

我一直在研究這一段時間，無法弄清楚我做錯了什麼。正在上傳文件，但INSERT不會將位置添加到數據庫中

該腳本看起來很簡單，並且正在將文件添加到服務器，但不會將該位置插入數據庫。代碼的INSERT部分失敗了，我在哪裏？

您必須執行您的查詢（$ sql）。 – hherger

你的'mysqli'查詢執行函數在哪裏？ –

是你的名字插入數據庫？如果它插入那麼查詢是正確的。嘗試在將圖像插入數據庫之後運行查詢，並使用時間戳更改圖像的名稱，這樣會很好，否則圖像的相同名稱可能會在某個級別引起混淆。 – nerdyDev

插入查詢是錯誤的，您的查詢更改爲以下：

$sql = "INSERT INTO candidate_images (name,image,district_id) VALUES ('$name','$pic','$district_id')"; 

mysqli_query($connection, $sql);

有關詳情，請參考：mysqli_query

我在這裏提供例如，如何插入到數據庫：

<?php 
    // Database connection establishment 
    $con=mysqli_connect("localhost","username","password","db_name"); 

    // Check connection 
    if (mysqli_connect_errno($con)) { 
    echo "MySQL database connection failed: " . mysqli_connect_error(); 
    } 

    $sql = "INSERT INTO candidate_images (name,image,district_id) VALUES ('$name','$pic','$district_id')"; 

    // Insert data into database 
    mysqli_query($con,$sql); 

?>

沒錯，$ pic上的尾部撇號丟失了，通過使用您的建議並添加mysqli_query並添加if（！mysql_query（$ sql））來找到它echo echo（'處理'。 '提交時發生數據庫錯誤。 \\ n如果此錯誤仍然存在，請' 'contact [email protected]。\\ n'。mysql_error（））; 非常感謝！ – iconMatrix

@iconMatrix最受歡迎.. :)高興地幫助。 –

$sql = "INSERT INTO candidate_images (`name`,`image`, `district_id`) VALUES ('$name','$pic','$district_id')";

使用您的mysql_*或mysqli_*或PDO功能在這裏執行查詢數據庫。

其實你的插入查詢是錯誤的。你只需要糾正它。它會正常工作。只需用我的下面的代碼替換你的代碼，別忘了執行保存在$ sql變量中的查詢。這也是必要的。如果我的工作不正常，請使用您自己的班級/模塊執行查詢。
