Discuz7.2 首页四格图片不刷新的解决方案

彻底解决这个问题有点麻烦

要修改3个地方

1.---------------------------------------------------------

修改检索图片的sql语句

pic.php

找到

    $fids = $searchfid ? 'AND '."t.fid IN ($searchfid)" : '';
    $data = array();
修改下面的sql语句为

$query = $db->query("SELECT attach.aid, attach.attachment, t.tid, t.fid, t.subject FROM {$tablepre}attachments attach LEFT JOIN {$tablepre}threads t ON t.tid=attach.tid WHERE attach.readperm='0' AND displayorder>='0' AND( filetype='image/pjpeg' or filetype='image/jpeg') $fids GROUP BY attach.tid ORDER BY $orderby DESC LIMIT $searchnums");

2.---------------------------------------------------------

批量上传，图片filetype总是application/octet-stream的BUG，及修改办法
/include/post.func.php

找到 list($width) = (array)$imagesize;

在它前面面添加

$imagesize['mime'] && $attach['type'] = $imagesize['mime'];

仅限图片。

3.---------------------------------------------------------

建立一个php文件,写入如下代码

这个文件的作用是

将filetype为"application/octet-stream "的jpg或者png图片数据修改成"image/jpeg "

<?php
$connect = mysql_connect("localhost","root","aaaa");
mysql_select_db("lsf100705",$connect);

$results = mysql_query("select aid,attachment from cdb_attachments");

while($row = mysql_fetch_array($results,MYSQL_NUM)){
    $ext = explode(".",$row[1]);
    if(($ext[1]=="jpg")or($ext[1]=="png")){
       
        $update = mysql_query("update cdb_attachments set filetype='image/jpeg' where aid=$row[0] ");
        //$updateResult = mysql_fetch_array($update,MYSQL_NUM);
        printf("%s:%s<br/>",$row[0] ,mysql_affected_rows());
    }   
}

mysql_free_result($results);

?>

这样就修改好了
