css

然后在,plus中新建立一个digg_ajax_list.PHP文件,内容为

11 }  
12 $maintable = 'archives';  
13 if($action == 'good')  
14 {  
15     $dsql->ExecuteNoneQuery("Update `$maintable` set scores = scores + {$cfg_caicai_add},goodpost=goodpost+1,lastpost=".time()." where id='$id'");  
16 }  
17 else if($action=='bad')  
18 {  
19     $dsql->ExecuteNoneQuery("Update `$maintable` set scores = scores - {$cfg_caicai_sub},badpost=badpost+1,lastpost=".time()." where id='$id'");  
20 }  
21 $digg = '';  
22 $row = $dsql->GetOne("Select goodpost,badpost,scores From `$maintable` where id='$id' ");  
23 if(!is_array($row))  
24 {  
25     exit();  
26 }  
27 if($row['goodpost']+$row['badpost'] == 0)  
28 {  
29     $row['goodper'] = $row['badper'] = 0;  
30 }  
31 else

33     $row['goodper'] = number_format($row['goodpost']/($row['goodpost']+$row['badpost']),3)*100;  
34     $row['badper'] = 100-$row['goodper'];  
35 }  
36   
37 if(empty($formurl)) $formurl = '';  
38 if($formurl=='caicai')  
39 { 
40     if($action == 'good') $digg = $row['goodpost'];  
41     if($action == 'bad') $digg  = $row['badpost'];

48 }  
49 AjaxHead();
