我有个问题。我想在页面中显示每个“主题”（标题），而不仅仅是像现在这样的第一个。当我添加一条新消息时，索引只显示第一条消息，只有当我单击“打开”按钮时，我才能看到所有消息。

有什么建议吗？

非常感谢。

这是解码代码：

<?php
require_once("config.php");
if (isset($_SESSION['username']) === FALSE){
    header('location:login.php');
    exit();
}
$where = "";
$searchCriteria = "";
if (isset($_GET['search']) && $_GET['search'] != '') {
    $searchCriteria = mysql_real_escape_string($_GET['search']);
    $where = " WHERE subject LIKE '%" . $searchCriteria . "%'";
    $where .= " OR message like '%" . $searchCriteria . "%'";
}
$sql = "SELECT * FROM notes " . $where . " LIMIT 30";
$result = mysql_query($sql);
?>

我认为你应该使用mysql_num_rows它并且你不需要你创建很多open，只需添加一次就像你一样close buttons，因为你必须添加喜欢while looprecords thenif conditionif(mysql-num_rows($result))

完整代码

<?php
    require_once("config.php");
    if (isset($_SESSION['username']) or $_SESSION['username']=== FALSE){
        header('location:login.php');
        exit();
    }
    $where = "";
    $searchCriteria = "";
    if (isset($_GET['search']) && $_GET['search'] != '') {
        $searchCriteria = mysql_real_escape_string($_GET['search']);
        $where = " WHERE subject LIKE '%" . $searchCriteria . "%'";
        $where .= " OR message like '%" . $searchCriteria . "%'";
    }
    $sql = "SELECT * FROM notes " . $where . " LIMIT 30";
    $result = mysql_query($sql);
?>

    });
    $("#closer").click(function(){
        $("#playbox").slideUp(600); 
    });
});
</script>

如果你想toggle分开，那么你必须像这样编码，

HTML

让有两个类似Create的记录HTML使用while loop

<div class="contentSubject">
    <input type="button" class="btnOpener" value="Open" />
    <div class="playbox">
        <!--your table goes here-->
    </div>
</div>

<div class="contentSubject">
    <input type="button" class="btnOpener" value="Open" />
    <div class="playbox">
        //your table goes here
    </div>
</div>

脚本

<script>
    $(document).ready(function(){
        $(".playbox").hide();
        $(".btnOpener").click(function(){
            $(this).closest('.contentSubject')
                   .find(".playbox").slideDown(600); 
        });
        // same code for close
    });
</script>

请尝试该代码

$("#opener").live("click",function(){
    $("#playbox").slideDown(600); 
});
