mysql_result（）期望参数1是resource，boolean给定 [英] mysql_result() expects parameter 1 to be resource, boolean given

问题描述

下面的代码给我的错误：

The code below gives me the error:

mysql_result() expects parameter 1 to be resource, boolean given

我已经双重检查了我的数据库，并且所有表/字段名称都正确。

I have double checked my database and all table/field names are correct.

还有其他原因会导致这个错误吗？

Are there any other reasons why I would get this error?

if(isset($_GET['action']))
    {
        $action = $_GET['action'];
            if($action == "edit")
            {
                $pid = $_GET['id'];
                $query = "SELECT * FROM tbl_pages WHERE page_id = '$pid'";
                $content = mysql_query($query);
                $page_title = mysql_result($content, 0, 'page_title');
                $page_content = mysql_result($content, 0, 'page_content');
                echo "<form action=\"save.php\" method=\"post\">                                                                
                        Page Title: <input type=\"text\" name=\"pagetitle\" value=$page_title><br />                                    
                        <textarea id=\"editor1\" type=\"text\" name=\"pagecontent\">$page_content</textarea>
                        <script type=\"text/javascript\">CKEDITOR.replace( 'editor1' );</script>
                        <input type=\"submit\">
                      </form>";
            } else {
                echo "<a href=\"editpage.php?action=edit&id=3\"><li>Setting up program/Adjusting preference</li></a>

            }
    } else {
        echo "<a href=\"editpage.php?action=edit&id=3\"><li>Setting up program/Adjusting preference</li></a>
                        <a href=\"editpage.php?action=edit&id=4\"><li>Choosing plugins</li></a>
                        <a href=\"editpage.php?action=edit&id=5\"><li>Basic Features/Functions</li></a>
                        <a href=\"editpage.php?action=edit&id=6\"><li>Creating a Drum Beat/Envelopes</li></a>
                        <a href=\"editpage.php?action=edit&id=7\"><li>Creating a Bass Wobble</li></a>

                        <a href=\"editpage.php?action=edit&id=9\"><li>Advanced Tools/Features</li></a>";    
    }

编辑：我双重检查连接和查询，出错了。我在页面的开头使用了非常类似的查询，除了使用mysqli_query，什么是mysqli的等效mysql_result？

I double checked the connection and query, still stuggling to find where ive gone wrong. I have used a very similar query at the start of the page except using mysqli_query, what is the equivalent mysql_result for mysqli? Does this make a difference?

感谢

推荐答案

do mysql_connect（）或者你忘记了吗？

Where do you do mysql_connect() or did you forget to do that?

如果这不是问题， p>

If that is not the problem, change

 $content = mysql_query($query);

加入

 $content = mysql_query($query) or die(mysql_error());

并告诉我们您的错误是什么。

and tell us what your error is.
