Below is the code to check file type in javascript..
<script type=”text/javascript” language=”javascript”>
function isImage(file) {
var image = /\.(jpg|jpeg|bmp|gif|png|jpe)$/i;
if (image.test(file))
return true;
else
return false;
}
function isAudio(file) {
var audio = /\.(mp3|wav|mid|midi|mp2|ul|ra|m3u|ram|rm)$/i;
if (audio.test(file))
return true;
else
return false;
}
function isArchive(file) {
var archive = /\.(zip|rar)$/i;
if (archive.test(file))
return true;
else
return false;
}
function isVideo(file) {
var video = /\.(mov|mpg|mpeg|avi|asf|wmv|mpe|3gp|swf)$/i;
if (video.test(file))
return true;
else
return false;
}
</script>
If you really want to validate uploaded file… you have to use “Mediainfo” on linux to check/validate file mime type.
MediaInfo provides technical and tag information about a video or audio file.
