如果用戶已經喜歡的東西顯示一條消息

Question

在我的Web應用程序中，我有2個按鈕：一個是「喜歡」，另一個是「不喜歡」。

用戶不能喜歡他們自己的配置文件。

我正在尋找一些代碼，以便如果數據庫檢查顯示已有一行用戶想要喜歡或不喜歡該配置文件，則會出現一條消息：「您已經喜歡此用戶」或「你已經不喜歡這個用戶」

<? if ($_POST['like']){ 
    if(strtolower($view) == strtolower($fetchAccount['UserName'])){ 
    echo "You cannot Like yourself!<br /><br/>"; 
    } else { 
    mysql_query("INSERT INTO `ProfileLikes` (`id`, `Profile`, `Rated`, 
     `LikedDisliked`, `Date`) VALUES ('', '{$fetchUser['UserName']}', 
     '{$fetchAccount['UserName']}', 'Liked', '$time')"); 
    echo "You Liked {$fetchUser['UserName']}!<br /><br />"; 
    } 
} 

if ($_POST['Dislike']){ 
    if(strtolower($view) == strtolower($fetchAccount['UserName'])){ 
    echo "You cannot DisLike yourself!<br /><br />"; 
    } else { 
    mysql_query("INSERT INTO `ProfileLikes` (`id`, `Profile`, `Rated`, 
     `LikedDisliked`, `Date`) VALUES ('', '{$fetchUser['UserName']}', 
     '{$fetchAccount['UserName']}', 'Disliked', '$time')"); 
    echo "You DisLiked {$fetchUser['UserName']}!<br /><br />"; 
    } 
} 
?> 

任何人都可以幫忙嗎？提前致謝。 :)

在這裏你走。

<?php 

//-------Like section--------- 
if ($_POST['like']){ 

    if(strtolower($view) == strtolower($fetchAccount['UserName'])){ 

    echo "You cannot Like yourself!<br /><br/>"; 

    } else { 

    //Check whether user 'liked' the other user already. 
    $selectQuery = "select * from `ProfileLikes` where `Profile` = '" . 
      $fetchUser['UserName'] ."' AND `Rated` = '" . 
      $fetchAccount['UserName'] . "' AND `LikedDisliked` = 'Liked' "; 
    $resultSetCheck = mysql_query($selectQuery); 
    $rowLikedExistsArray = mysql_fetch_assoc($resultSetCheck); 

    if (!empty($rowLikedExistsArray)) { 

     //He 'liked' it already! 
     echo "You have already liked this user! <br /><br/>"; 

    } else {   

     //insert new 'like' 
     mysql_query("INSERT INTO `ProfileLikes` (`id`, `Profile`, `Rated`, 
      `LikedDisliked`, `Date`) VALUES ('', '{$fetchUser['UserName']}', 
      '{$fetchAccount['UserName']}', 'Liked', '$time')"); 
     echo "You Liked {$fetchUser['UserName']}!<br /><br />"; 

    } 
    } 
} 

//-------Dislike section--------- 
if ($_POST['Dislike']){ 

    if(strtolower($view) == strtolower($fetchAccount['UserName'])){ 

    echo "You cannot DisLike yourself!<br /><br />"; 

    } else { 

    //Check whether user 'disliked' the other user already. 
    $selectQuery = "select * from `ProfileLikes` where `Profile` = '" . 
      $fetchUser['UserName'] ."' AND `Rated` = '" . 
      $fetchAccount['UserName'] . "' AND `LikedDisliked` = 'Disliked' "; 
    $resultSetCheck = mysql_query($selectQuery); 
    $rowDislikedExistsArray = mysql_fetch_assoc($resultSetCheck); 

    if (!empty($rowDislikedExistsArray)) { 

     //He 'disliked' it already! 
     echo "You have already disliked this user! <br /><br/>"; 

    } else { 
     //insert new dislike 
     mysql_query("INSERT INTO `ProfileLikes` (`id`, `Profile`, `Rated`, 
      `LikedDisliked`, `Date`) VALUES ('', '{$fetchUser['UserName']}', 
      '{$fetchAccount['UserName']}', 'Disliked', '$time')"); 
     echo "You DisLiked {$fetchUser['UserName']}!<br /><br />"; 
    } 

    } 
} 

?> 

注：我可以看到一些優化。但不想破壞你的代碼流。
