先引入jQuery與ajaxFileUpload外掛。注意先後順序,這個不用說了,所有的插件都是這樣。
<script src="__ADMIN__/js/jquery.min.js?v=2.1.4"></script> <script src="__ADMIN__/js/ajaxfileupload.js"></script>
<div class="form-group"> <label class="col-sm-2 control-label">缩略图</label> <div class="col-sm-8"> <div id="file-pretty"> <div> <input type="file" id="file_thumb" name="thumb" class="form-control" value=""> <div class="input-append input-group"> <span class="input-group-btn"> <button id="btn_thumb" class="btn btn-white" type="button">选择图片</button> </span> <input id="info_thumb" name="thumb" class="input-large form-control" type="text" value="{$info.img}"> </div> </div> </div> </div> <div class="col-sm-2"><img id="show_thumb" src="/uploads/image/{$info.thumb}" alt=""></div> </div>
<script type="text/javascript"> $(function(){ $("#btn_thumb").click(function(){ $("#file_thumb").click(); }); //异步上传 $("body").delegate('#file_thumb', 'change', function(){ var filepath = $("input[name='thumb']").val(); var arr = filepath.split('.'); var ext = arr[arr.length-1]; //alert(filepath);exit(); if('gif|jpg|png|bmp'.indexOf(ext)>=0){ $.ajaxFileUpload({ url: '/admin/slide/upload_image', secureurl: false, fileElementId: 'file_thumb', //file标签ID dataType: 'json', //返回数据类型 data:{name:'thumb'}, success:function (data,status){ $("#info_thumb").val(data); $("#show_thumb").attr('src','/uploads/images/'+data); $("#info_thumb").focus(); }, complete:function (XMLHttpRequest){ }, error:function (data,status,e){ layer.alert('上传失败!'); }, }); } else { //清空file $("#file_thumb").val(""); layer.alert('请上传合适的图片类型!'); } }); }); </script>
//单文件(包含单文件)异步上传 public function upload_image(){ //图片上传 $file = request()->file(input('name')); $info = $file->move(ROOT_PATH . 'public/uploads/images'); if($info) { return json_encode($info->getSaveName()); } }
<div id="slideshow"> <ul class="rslides" id="slider"> {volist name="data" id="vo"} <li><a href="{$vo.url}" rel="external nofollow" rel="bookmark" target="_blank"> <img src="__UPLOADS__/images/{$vo.img}" max-width="" max-height="" alt="{$vo.title}"></a> <p class="slider-caption">{$vo.title}</p> </li> {/volist} </ul> </div>
