我刚开始学习Jplugin开发，所以在这里我做了一个小投票脚本。这里一切正常，但我希望 conf.php 文件以 joomla 框架样式制作。正如您在此处看到的，1 和 2 个文件完美地结合在一起。我想使用第三个示例而不是第二个示例，其中我使用简单的 php 代码。我尝试做的最后一个示例是使用 joomla 框架，但它不起作用。我不知道该代码有什么问题。任何人看到都可以告诉我在哪里犯了错误，或者可能远离正确吗？
<?php
defined( '_JEXEC' ) or die;
?>
<?php
class plgSystemRatingx extends JPlugin
{
public function onContentBeforeDisplay()
{
?>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$(".like").click(function()
{
var id=$(this).attr("id");
var name=$(this).attr("name");
var dataString = 'id='+ id + '&name='+ name;
$("#votebox").slideDown("slow");
$("#flash").fadeIn("slow");
$.ajax
({
type: "POST",
url: "conf.php",
data: dataString,
cache: false,
success: function(html)
{
$("#flash").fadeOut("slow");
$("#content").html(html);
}
});
});
$(".close").click(function()
{
$("#votebox").slideUp("slow");
});
});
</script>
<body>
<div style="margin:50px">
<a href="#" class="like" id="1" name="up">Like</a> -- <a href="#" class="like" id="1" name="down">Dislike</a>
<div id="votebox">
<span id='close'><a href="#" class="close" title="Close This">X</a></span>

return true;
}
}
这段代码完美运行
<?php
$mysql_hostname = "localhost";
$mysql_user = "px";
$mysql_password = "px";
$mysql_database = "jum";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password)
or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");
if($_POST['id'])
{
$id=mysql_real_escape_string($_POST['id']);
$name=mysql_real_escape_string($_POST['name']);
mysql_query("update messages set $name=$name+1 where id='$id'");
$result=mysql_query("select up,down from messages where id='$id'");
$row=mysql_fetch_array($result);
$up_value=$row['up'];
$down_value=$row['down'];
$total=$up_value+$down_value;
$up_per=($up_value*100)/$total;
$down_per=($down_value*100)/$total;
?>
<div style="margin-bottom:10px">
<b>Ratings for this blog</b> ( <?php echo $total; ?> total)
</div>
<table width="700px">
<tr>
<td width="30px"></td>
<td width="60px"><?php echo $up_value; ?></td>
<td width="600px"><div id="greebar" style="width:<?php echo $up_per; ?>%"></div></td>
</tr>
<tr>
<td width="30px"></td>
<td width="60px"><?php echo $down_value; ?></td>
<td width="600px"><div id="redbar" style="width:<?php echo $down_per; ?>%"></div></td>
</tr>
</table>
<?php
}
?>
这以joomla风格制作的根本不起作用
<?php
defined( '_JEXEC' ) or die;
?>
<?php
if(JRequest::getVar('id'))
{
$id = JRequest::getInt('id');
$name = JRequest::getInt('name');
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query2 = $db->getQuery(true);
$queryup = $db->getQuery(true);
$querydown = $db->getQuery(true);
$query->update('messages');
$query->set("message = 1");
$query->where("id = $id");
$query2->select('up,down');
$query2->from('messages');
$query2->where("id = $id");
$queryup->select('up');
$queryup->from('messages');
$queryup->where("id = $id");
$querydown->select('down');
$querydown->from('messages');
$querydown->where("id = $id");
$db->setQuery( $query );
$db->query();
$db->setQuery( $query2 );
$db->query();
$db->setQuery( $queryup );
$data0 = $db->query();
$db->setQuery( $querydown );
$data1 = $db->query();
$up_value= $db->insertid($data0);;
$down_value = $db->insertid($data1);
$total=$up_value+$down_value;
$up_per=($up_value*100)/$total;
$down_per=($down_value*100)/$total;
?>
<table width="700px">
<tr>
<td width="30px"></td>
<td width="60px"><?php echo $up_value; ?></td>
