Php 我的链接没有正确重定向

在我的数据库中运行搜索后，结果以链接的形式显示，以便将我重定向到特定页面…例如，当我搜索一个类别业务时，它会显示该类别，但当我单击它时，它会将我重定向到另一个类别的内容..当我检查我的url时，我注意到类似的内容

http://mysite/forum%20part%20two/view_category.php?cid=1

而不是

http://mysite/forum%20part%20two/view_category.php?cid=2

这是我的搜索代码

 if(isset($_POST['search'])){ //form submitted, clicked Submit Search 
    $query = strip_tags(mysql_real_escape_string($_POST['query'])); //try to prevent sql injections
    if(!$query){ //not enterered a query 
        echo 'You must enter a search query!'; 
    }else{ 
        //EDIT THIS ---------------------------------- 
        $table = 'categories'; //the table you want to search 
        $row = 'category_title'; //the row in which you want to search 
        //EDIT THIS ---------------------------------- 
        $sql = mysql_query("SELECT * FROM `".$table."` WHERE `".$row."` LIKE '%".$query."%'"); //search query 
        if($sql){ //no errors 
            if(mysql_num_rows($sql) == 0){ //No results found. 
                echo 'No results were found for <strong>'.$query.'</strong>'; 
            }else{ //one or more results have been found 
                echo 'We have found <strong>'.mysql_num_rows($sql).'</strong> for <strong>'.$query.'</strong>.<br><br> 
                <table> 
                    <tbody> 
                        <tr> 

                            <td><strong>category_title</strong></td> 
                        </tr>'; 
                while($r = mysql_fetch_array($sql)){ //get data of every user where their category_title is like the $query string 

                    $category_title = $r["category_title"]; 
                    //lets put the part they searched in bold. 
                    $category_title = str_ireplace($query, '<strong>'.$query.'</strong>', $category_title); 
                    //lets put the part they searched in bold. 
                    echo '<td>'.$category_title."<a href='view_category.php?cid=".$id."' class='cat_links'>".$category_title." - <font size='-1'>".$description."</font></a></td> 
                </tr>'"; 
                } 
                echo '</tbody></table>'; 
            } 
        }else{ 
            echo 'Sorry, an MySQL error occurred:<br><br>'.mysql_error(); //an error occurred, so echo it 
        } 
    } 
}

我的view_category.php代码如下

<?php

很抱歉粘贴了很多代码

            echo '<td>'.$category_title."<a href='view_category.php?cid=".$id."' class='cat_links'>".$category_title." - <font size='-1'>".$description."</font></a></td> 
        </tr>'";

也许我会

 $id = $r["id"];

@diEcho抱歉，我只是不知道我在哪里犯了一个错误如果你在URL中出现%20的问题，然后尝试在不同的浏览器中运行是的，那么你必须检查你的数据库中的字段名以获取你的id。我们无法从你的其他文件中分辨出来，它看起来像字段名是id。因此我更新了我的建议。试试看

 $id = $r["id"];
