PHP插入查詢不起作用，並沒有給出任何錯誤

嘿那裏對不起，如果這個問題可能已被問太多，但沒有一個問題，我在網站上看到的幫助我，並作爲標題指出，我有一個插入查詢會爲我正在創建的網站創建一個帳戶，但是當我按下提交按鈕時它什麼都不會做......只需刷新頁面即可。PHP插入查詢不起作用，並沒有給出任何錯誤

注：包括數據庫。 這部分網站包含在signup.php和signup.php中，包含連接文件。 經過測試，我可以從connect.php獲取，所以我不認爲這是問題所在。 即使這並不能證明爲什麼代碼不會始終運行。

故障排除和測試後，我想通了，通過去除這部分代碼：

 if (
     $username_error_message_status = false 
     and $password_error_message_status = false 
     and $email_error_message_status = false 
     and $bot_check_error_message_status = false 
    ) {

代碼工作尚未插入查詢語句沒有。所以任何形式的幫助將不勝感激，並感謝您的閱讀。

全碼：

分享你的表（'用戶'）模式嗎？ – C2486

編輯..也許添加connect.php以及如果它有幫助？ @Rishi – Jad

不能真正遵循這個邏輯，但你可能應該使用預先準備的語句，而不是直接在插入/選擇查詢中的變量，因爲這會讓你打開SQL注入... –

你如果查詢應該如下刪除：

if (
    $username_error_message_status == false 
    and $password_error_message_status == false 
    and $email_error_message_status == false 
    and $bot_check_error_message_status == false 
) {

您需要使用雙等號（==）不如果要比較值，則在if語句中使用單個（=）。

感謝您的答案..在我的舊代碼我曾經把單（=），但由於某種原因，即使代碼現在運行的數據沒有插入...但我想這是一部分完成。 – Jad
