迅睿cms多文件上传自定义函数，根据文件类型显示不同的链接

如果文件是链接也可以判断

函数复制到：/config/custom.php

// 检查附件类型
function checkAttachmentType($filename) {
// 获取附件扩展名
$extension = pathinfo($filename, PATHINFO_EXTENSION);
// 判断附件类型
if (in_array(strtolower($extension), array(‘jpg’, ‘jpeg’, ‘png’))) {
return ‘image’;
} elseif (in_array(strtolower($extension), array(‘mp3’))) {
return ‘audio’;
} elseif (in_array(strtolower($extension), array(‘mp4’))) {
return ‘video’;
} elseif (in_array(strtolower($extension), array(‘ppt’, ‘pptx’))) {
return ‘ppt’;
} elseif (in_array(strtolower($extension), array(‘pdf’))) {
return ‘pdf’;
} else {
return ”;
}
}
// 显示附件
function showAttachment($filename) {
$attachmentType = checkAttachmentType($filename);
switch ($attachmentType) {
case ‘image’:
echo ‘<img src=”‘ . $filename . ‘” alt=”Image”>’;
break;
case ‘audio’:
echo ‘<audio src=”‘ . $filename . ‘” controls></audio>’;
break;
case ‘video’:
echo ‘<video src=”‘ . $filename . ‘” controls></video>’;
break;
case ‘ppt’:
echo ‘<iframe src=”https://view.officeapps.live.com/op/view.aspx?src=’ . $filename . ‘” width=”100%” height=”500px” frameborder=”0″></iframe>’;
break;
case ‘pdf’:
echo ‘<embed src=”‘ . $filename . ‘” type=”application/pdf” width=”100%” height=”500px”>’;
break;
default:
echo ‘Invalid attachment type!’;
break;
}
}

模板调用方法

{php $filename = dr_get_file($c.file);}

{php showAttachment($filename);}
