我正在研究一個'updateProfile'web服務,用戶可以更新一個或多個字段,我被難住爲如何形成查詢。我認爲如果isset條件可以有多個,並根據需要在內容上進行匹配。不過,我會碰上哪些是發佈的時間提前,因此不知道是否包括與運算或逗號等。這裏是我的出發點不知道的問題:如何更新一行中的多個字段,而不必知道哪些將被提前更新
$UpdateTradesman_Query= "UPDATE Tradesmen SET ";
if(isset($_REQUEST['FName'])){
$FName=mysql_real_escape_string($_POST['FName']);
$UpdateTradesman_Query.= "FName ='".$FName."'";
}
if(isset($_REQUEST['SName'])){
$SName=mysql_real_escape_string($_POST['SName']);
$UpdateTradesman_Query.= "SName ='".$SName."'";
}
if(isset($_REQUEST['Email'])){
$Email=mysql_real_escape_string($_POST['Email']);
$UpdateTradesman_Query.= "Email ='".$Email."'";
}
if(isset($_REQUEST['HomePhone'])){
$HomePhone=mysql_real_escape_string($_POST['HomePhone']);
$UpdateTradesman_Query.= "HomePhone ='".$HomePhone."'";
}
if(isset($_REQUEST['Mobile'])){
$Mobile=mysql_real_escape_string($_POST['Mobile']);
$UpdateTradesman_Query.= "Mobile ='".$Mobile."'";
}
if(isset($_REQUEST['Trade'])){
$Trade=mysql_real_escape_string($_POST['Trade']);
$UpdateTradesman_Query.= "Trade ='".$Trade."'";
}
if(isset($_REQUEST['Address'])){
$Address=mysql_real_escape_string($_POST['Address']);
$UpdateTradesman_Query.= "Address ='".$Address."'";
}
if(isset($_REQUEST['County'])){
$County=mysql_real_escape_string($_POST['County']);
$UpdateTradesman_Query.= "County ='".$County."'";
}
if(isset($_REQUEST['PostCode'])){
$PostCode=mysql_real_escape_string($_POST['PostCode']);
$UpdateTradesman_Query.= "PostCode ='".$PostCode."'";
}
if(isset($_REQUEST['Photo'])){
$Photo=mysql_real_escape_string($_POST['Photoe']);
$UpdateTradesman_Query.= "Photo ='".$Photo."'";
}
if(isset($_REQUEST['Profile'])){
$Profile=mysql_real_escape_string($_POST['Profile']);
$UpdateTradesman_Query.= "Profile ='".$Profile."'";
}
if(isset($_REQUEST['Qualification'])){
$Qualification=mysql_real_escape_string($_POST['Qualification']);
$UpdateTradesman_Query.= "Qualification ='".$Qualification."'";
}
if(isset($_REQUEST['AvailabilityTimes'])){
$AvailabilityTimes=mysql_real_escape_string($_POST['AvailabilityTimes']);
$UpdateTradesman_Query.= "AvailabilityTimes ='".$AvailabilityTimes."'";
}
$UpdateTradesman_Query.= "WHERE TradesmanID=".$TradesmanID;
echo $UpdateTradesman_Query;
if (mysql_query($UpdateTradesman_Query)){
$status= 'OK';
$message= 'null';
$Update= "OK";
}
else{
$status= 'Not OK';
$message= 'Error: Query Unsuccessful.'. mysql_error();
$Update= "Not OK";
}
我也有考慮到如果用戶選擇更新用戶名或電子郵件,我必須確保:a)電子郵件尚未與另一個帳戶(已在數據庫中)關聯,或b)用戶名尚未被使用。任何幫助讚賞。
由於不正是我需要的。 – user2363025
