什麼似乎是錯誤？

Answer 1

爲了使其工作，我所要做的就是添加引號並從函數中刪除引號。

$sql = "INSERT INTO customer_registration("; 
$sql .= "CUSTOMER_FNAME, CUSTOMER_LNAME, CUSTOMER_DOB, APARTMENT, "; 
$sql .= "STREET, CITY, PROVINCE, POSTAL_CODE, EMAIL, PHONE, SIGN_IN_DATE "; 
$sql .= ") VALUES ("; 
$sql .= " '{$fname}', '{$lname}', '{$dob}', '{$apt}', '{$street}', '{$city}', '{$province}', '{$postalCode}', '{$_email}', '{$phone}', NOW()"; 
$sql .= ")"; 

Answer 2

1）在你們第一次約會使用strtotime()。然後date('Y-m-d')將其轉換回來。

2）在您的值中使用單引號'。像'{$lname}'

3）從現在刪除單引號'（）

<? 
$dob = strtotime($dob); 
$dob = date('%m/%d/%Y',$dob); 

$sql = "INSERT INTO customer_registration("; 
$sql .= "CUSTOMER_FNAME, CUSTOMER_LNAME, CUSTOMER_DOB, APARTMENT, "; 
$sql .= "STREET, CITY, PROVINCE, POSTAL_CODE, EMAIL, PHONE, SIGN_IN_DATE "; 
$sql .= ") VALUES ("; 
$sql .= " '{$fname}', '{$lname}', '{$dob}', '{$apt}', '{$city}', '{$province}', '{$postalCode}', '{$_email}', '{$phone}', NOW()"; 
$sql .= ")"; 
$result= mysqli_query($connection, $sql); 

?>
