这篇文章主要介绍了使用jquery.form.js实现图片上传的方法,涉及jquery使用表单插件jquery.form.js进行图片上传的提交、类型验证、执行结果回调显示等技巧,非常简单实用,需要的朋友可以参考下
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';
?>

});
});
});
</script>

<body>
文件上传
<form enctype="multipart/form-data" id="form1" method="post" action="">
文件:
<input type="file" name="upfile" id="upfile"><input type="button" id="upimage" value="图片上传1">
<input type="text" name="im1" id="im1" value="" />
</form>
<form enctype="multipart/form-data" id="form2" method="post" action="">
文件:
<input type="file" name="upfile" id="upfile2"><input type="button" id="upimage2" value="图片上传2">
<input type="text" name="im2" id="im2" value="" />
</form>
<div id="ln">tu</div><br>
<div id="ln2">tu2</div>
</body>
</html>
