我在上传文件时遇到问题。我看到文件名被发布到数据库,但文件没有被发布到图像文件夹。好像什么都没有发生。这是我的以下代码,请告诉我需要更改的内容:
<?php
//the $art variable gets posted to a database eventually
$art = mysql_real_escape_string(stripslashes($_FILES["art"]["name"]));
$art_ext = pathinfo($art, PATHINFO_EXTENSION);
$art = md5($art).".".$art_ext;
if($art!=""){
move_uploaded_file($art, "images/".$art );
}
?>
<script type="text/javascript">
$(function(){
image_upload = {
UpdatePreview: function(obj){
// if IE < 10 doesn't support FileReader
if(!window.FileReader){
// don't know how to proceed to assign src to image tag
} else {
var reader = new FileReader();
var target = null;
reader.onload = function(e) {
target = e.target || e.srcElement;
$("#imageupload").attr("src", target.result);
};
reader.readAsDataURL(obj.files[0]);
}
}
};
});
</script>
<form action="new.php" method="post" enctype="multipart/form-data">
<input type='file' name='art' id="file" onchange='image_upload.UpdatePreview(this)' value="Upload" accept="image/gif,image/jpeg,image/png"/>
</p>
<p>upload a image! (.gif, .jpg, .png formats allowed. 5MB max)</p>
<img id="imageupload" src="1x1.png" alt="test" />
<input type="submit" class="smallbtn4" style="cursor:pointer;" value="post"/>
</form>
