本文实例讲述了Thinkphp框架 Layui实现图片/文件上传功能。分享给大家供大家参考,具体如下:
在项目中用到了,再网上找了现成的代码都是借口异常或者非法上传,所以在一番摸索搞定之后拿来和大家分享。
html:
代码语言:javascript复制<form class="layui-form layui-form-pane" action="" style="margin-top:20px;" enctype="multipart/form-data"
<center
<div class="layui-upload-drag" id="uploadBanner"
<img class="layui-upload-img" id="upload-photo"
<i class="layui-icon" id="upload-icon" </i
<p 点击上传,或将文件拖拽到此处</p
<p 建议尺寸1920*512</p
</div
<input type="hidden" id="res" name="banner_photo" value="" lay-verify="required" /
<div class="layui-form-item" style="margin-top:10px;"
<button class="layui-btn" lay-submit="" lay-filter="sub" 提交</button
</div
<div id="demoText" </div
</center
</form
JS:
代码语言:javascript复制layui.use('upload', function(){
var $ = layui.jquery
,upload = layui.upload;
//普通图片上传
var uploadInst = upload.render({
elem: '#uploadBanner'
,url: "{:U('Api/doUploadPic')}"
,before: function(obj){
//预读本地文件示例,不支持ie8
obj.preview(function(index, file, result){
$('#upload-photo').attr('src', result); //图片链接(base64)
$('#upload-photo').attr('style', 'height:10rem;');
$('#upload-icon').attr('style','display:none;');
});
}
,done: function(res, index, upload){
//如果上传失败
if(res.code 0){
return layer.msg('上传失败');
}
//上传成功
console.log("成功啦!" obj2string(res) " " index " " upload);
}
,error: function(){
//演示失败状态,并实现重传
var demoText = $('#demoText');
demoText.html('<span style="color: #FF5722;" 上传失败</span <a class="layui-btn layui-btn-xs demo-reload" 重试</a ');
demoText.find('.demo-reload').on('click', function(){
uploadInst.upload();
});
}
});
});
PHP接口:
代码语言:javascript复制public function doUploadPic()//上传模块
{
$upload = new ThinkUpload();
$upload- maxSize = 3145728;
$upload- exts = array('jpg', 'gif', 'png', 'jpeg');
$upload- rootPath = './Public/'; // 设置附件上传根目录
$upload- savePath = 'upload/'; // 设置附件上传子目录
$info = $upload- upload();
if(!$info){
$this- error($upload- getError());
}else{
foreach($info as $file){
$data = '/Public'.$file['savepath'] . $file['savename'];
$file_a=$data;
echo '{"code":0,"msg":"成功上传","data":{"src":"'.$file_a.'"}}';
}
}
}
图片就上传到/Public/upload文件夹下了:
