本文实例讲述了使用jquery.form.js实现图片上传的方法。分享给大家供大家参考，具体如下：
testupfile2.php
<?php header('Content-type:text/html;charset=utf-8'); include_once 'includes/common.inc.php'; if(!empty($_FILES['upfile'])){ //文件格式 $image=array('image/jpg', 'image/jpeg', 'image/png', 'image/pjpeg', 'image/gif', 'image/bmp', 'image/x-png' ); $updir=$_SERVER['DOCUMENT_ROOT'].$_config['g']['baseUrl'].'/attached/images/'; $upfile=$_FILES['upfile']; $name=$upfile['name']; $ext=substr($upfile['name'],strpos($upfile['name'],'.')); $upname=md5(time().rand(1, 1000)).$ext; $type=$upfile['type']; $size=$upfile['size']; $tmp_name=$upfile['tmp_name']; $error=$upfile['error']; $ok=0; foreach ($image as $key=>$value) { if($type==$value)$ok=1; } if($ok=='1' && $error=='0'){ move_uploaded_file($tmp_name,$updir.$upname); //echo '<br>'.$tmp_name.'<br>'.$upname.'<br>'.$updir.'<br>'.$ext.'上传成功'; //echo '上传成功'; echo $upname; //$im=$updir.$upname; //echo $im; //echo '<img src='.$updir.$upname.' />'; //$views->assign('image',$upname); //$views->display('default/testupfile.html'); } else echo '上传失败2'; } else echo '上传失败1'; ?>
testupfile.html
