自己做的主页,希望主页每个栏目板块都可以显示带有缩略图的代码
有10万篇文章,有两百篇下载图片到本地服务器,怎样写随机调用多张缩略图的代码?
例如下列代码,有缩略图和没有图片的全部随机显示,怎么改动让它只显示含有缩略图的文章?
<?php $arrlist = thread_tid_find(1, 5000);
if ($arrlist) {
$threads = count($arrlist);
$total = $threads > 6 ? 6 : $threads;
$tidarr = $threads > 6 ? array_rand($arrlist, $total) : array_keys($arrlist);
$arrlist = well_thread_find_asc($tidarr, $total);
}
?>
<?php if($arrlist){ ?>
<?php foreach($arrlist as $_thread) { ?>
