我正在使用foreach循環來檢查並插入新標籤。爲什麼這個if else條件無法正常工作?
但是兩個條件(if和alse)同時應用,而不管mysql發現的id是否等於foreach發佈的ID。 PLZ幫助
$new_tags = $_POST['new_tags']; //forget the mysl security for the time being
foreach ($new_tags as $fnew_tags)
{
$sqlq = mysqli_query($db3->connection, "select * from o4_tags limit 1");
while($rowq = mysqli_fetch_array($sqlq)) {
$id = $rowq['id'];
if($id == $fnew_tags) { //if ID of the tag is matched then do not insert the new tags but only add the user refrence to that ID
mysqli_query($db3->connection, "insert into user_interests(uid,tag_name,exp_tags) values('$session->userid','$fnew_tags','1')");
}
else
{ //if ID of the tag is not matched then insert the new tags as well as add the user refrence to that ID
$r = mysqli_query($db3->connection, "insert into o4_tags(tag_name,ug_tags,exp_tags) values('$fnew_tags','1','1')");
$mid_ne = mysqli_insert_id($db3->connection);
mysqli_query($db3->connection, "insert into user_interests(uid,tag_name,exp_tags) values('$session->userid','$mid_ne','1')");
}
}
}
我不認爲if/else的兩個部分都實際執行。嘗試僅在控制檯而不是查詢中打印某些內容,這很可能是if/else內部代碼中的錯誤。 – sashkello 2013-04-10 03:21:05
