thinkphp结合layui上传图片

简单示例：

<script type="text/javascript">

layui.use(['form', 'layedit','element', 'laydate','upload'], function(){

    var form = layui.form;

    var layer = layui.layer;

    var layedit = layui.layedit;

    var laydate = layui.laysdate;

    // 上传

    var upload = layui.upload;

    var uploadInst1 = upload.render({

    elem: '#uploadImgBut1', //绑定元素

    url: "{:U('Admin/Upload/layuiupload')}",//上传接口

    done: function(res){

        if(res['state'] ==1){

            layer.msg(res['message']);

            $("#uploadImg1").attr('src',res['path']).show();

            $("input#uploadImgSrc1").val(res['path']);

        };

    }

    });

});

</script>

后台代码：

public function layuiupload(){

        $upload = new \Think\Upload();// 实例化上传类

        $imgSize = intval(CP('IMGSIZE'));

        $imgType = CP('IMGTYPE');

        $imgSize = !empty($imgSize) ? $imgSize : 3145728;

        $imgType = !empty($imgType) ? explode(',',$imgType) : array('jpg','gif','png','jpeg');

        $upload->maxSize   =     $imgSize;// 设置附件上传大小

        $upload->exts      =     $imgType;// 设置附件上传类型

        $upload->rootPath  =     "./uploads/Picture/"; // 设置附件上传根目录

        $upload->savePath  =     ''; // 设置附件上传（子）目录

        $data = array();

        $data['state'] = 1;

        $data['message'] = '上传成功';

        $data['path'] = '';

        // 上传文件

        $info = $upload->upload();

        if(!$info){

            $data['state'] = 0;

            $data['message'] ='上传失败';

        };

        $path = "uploads/Picture/".$info['file']['savepath'].$info['file']['savename'];

        $data['path'] = $path;

        echo json_encode($data);die;

    }

上传图片，压缩和裁剪

public function layuiupload(){

    $upload = new \Think\Upload();// 实例化上传类

    $image = new \Think\Image();

    $imgSize = intval(CP('IMGSIZE'));

    $imgType = CP('IMGTYPE');

    $imgSize = !empty($imgSize) ? $imgSize : 3145728;

    $imgType = !empty($imgType) ? explode(',',$imgType) : array('mp4','jpg','gif','png','jpeg');

    $upload->thumb     =     true;

    $upload->maxSize   =     $imgSize;// 设置附件上传大小

    $upload->exts      =     $imgType;// 设置附件上传类型

    $upload->rootPath  =     "./Uploads/Picture/"; // 设置附件上传根目录

    $upload->savePath  =     ''; // 设置附件上传（子）目录

    $data = array();

    $data['state'] = 1;

    $data['message'] = '上传成功';

    $data['path'] = '';

    // 上传文件

    $info = $upload->upload();

    if(!$info){

        $data['state'] = 0;

        $data['message'] ='上传失败';

    };

    $path = "/Uploads/Picture/".$info['file']['savepath'].$info['file']['savename'];

    $image->open(".".$path);

    $image->thumb(230, 160,\Think\Image::IMAGE_THUMB_FIXED)->save(".".$path);

    $data['path'] = $path;

    echo json_encode($data);die;

}
