Discuz! 帖子内容页图片居中的方法

1、打开 template/default/forum/discuzcode.htm 模板文件，查找：

1. <img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '{$_G[setting][showexif]}')" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes&#172;humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode{else}{$attach[url]}$attachthumb{/if}" inpost="1"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} />

复制代码

修改为：

1. <div style="text-align:center;"><img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '{$_G[setting][showexif]}')" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes&#172;humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode{else}{$attach[url]}$attachthumb{/if}" inpost="1"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} /></div>

复制代码

再查找：

1. <img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes&#172;humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes{else}{$attach[url]}$attach[attachment]{/if}" $widthcode id="aimg_$attach[aid]" inpost="1"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} />

复制代码

修改为：

1.                                                 <div style="text-align:center;"><img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes&#172;humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes{else}{$attach[url]}$attach[attachment]{/if}" $widthcode id="aimg_$attach[aid]" inpost="1"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} /></div>

复制代码

2、打开 source\function\function_discuzcode.php 文件，查找：

1. else {
   
2. $img = '<img id="aimg_'.$rimg_id.'" class="zoom"'.($width > 0 ? ' width="'.$width.'"' : '').($height > 0 ? ' height="'.$height.'"' : '').' '.$attrsrc.'="{url}" '.($extra ? $extra.' ' : '').'border="0" alt="" />';
   
3.                 }

复制代码

修改为：

1. else {
   
2. $img = '<div style="text-align:center;"><img id="aimg_'.$rimg_id.'" class="zoom"'.($width > 0 ? ' width="'.$width.'"' : '').($height > 0 ? ' height="'.$height.'"' : '').' '.$attrsrc.'="{url}" '.($extra ? $extra.' ' : '').'border="0" alt="" /></div>';
   
3.                 }

复制代码

然后到后台更新缓存。
