在本篇文章裏小編給大家整理的是關於php結合layui前端實現多圖上傳的實例內容，有需要的朋友們可以參考下。
php結合layui前端實現多圖上傳
前端html代碼
<div class="layui-upload">
<button type="button" class="layui-btn layui-btn-normal" id="testList">請選擇圖片</button>
<span class="num_pic"></span>
<div class="layui-upload-list">
<table class="layui-table">
<thead>
<tr>
<th>文件名</th>
<th id="pic">圖片預覽</th>
<th>大小</th>
<th>狀態</th>
<th id="cao">操作</th>
</tr>
</thead>
<tbody id="demoList"></tbody>
</table>
</div>
<button type="button" class="layui-btn" id="testListAction">開始上傳</button>
<span class="num_pic"></span>
</div>
js 代碼
<script type="text/javascript">
layui.use('upload', function() {
var $ = layui.jquery,
upload = layui.upload;
//多文件列表示例
var demoListView = $('#demoList'),
uploadListIns = upload.render({
elem: '#testList',
url: "{url('pic/index/upload')}",
accept: 'images',
acceptMime: 'image/*',
size: 8192,
multiple: true,
number: 400,
auto: false,
exts: 'jpg|png|jpeg',
bindAction: '#testListAction',
choose: function(obj) {
var files = this.files = obj.pushFile(); //將每次選擇的文件追加到文件隊列
//讀取本地文件
obj.preview(function(index, file, result) {
var tr = $(['<tr id="upload-' + index + '">', '<td>' + file.name + '</td>', '<td><img src="' + result + '" alt="' + file.name + '" style="width: 100px;height: 40px;"></td>', '<td>' + (file.size / 1014).toFixed(1) + 'kb</td>', '<td>等待上傳</td>', '<td>', '<button class="layui-btn layui-btn-xs demo-reload layui-hide">重傳</button>', '<button class="layui-btn layui-btn-xs layui-btn-danger demo-delete">刪除</button>', '</td>', '</tr>'].join(''));
//單個重傳
tr.find('.demo-reload').on('click', function() {
obj.upload(index, file);
$("#upload-" + index).find("td").eq(2).html((file.size / 1014).toFixed(1) + 'kb');
});
//刪除
tr.find('.demo-delete').on('click', function() {
delete files[index]; //刪除對應的文件
tr.remove();
uploadListIns.config.elem.next()[0].value = ''; //清空 input file 值，以免刪除後出現同名文件不可選
});
demoListView.append(tr);
$(".num_pic").text("總共【" + demoListView.find("tr").length + "】張圖片");
});
},
done: function(res, index, upload) {
if(res.code == 0) { //上傳成功
$("#cao").text("地址");
var tr = demoListView.find('tr#upload-' + index),
tds = tr.children();
tds.eq(3).html('<span style="color: #5FB878;">上傳成功</span>');
tds.eq(4).html('<input type="text" name="imgs[]" value="' + res.file + '" class="layui-input" />'); //清空操作
return delete this.files[index]; //刪除文件隊列已經上傳成功的文件
}
this.error(index, upload);
},
allDone: function(obj) { //當文件全部被提交後，才觸發
layer.msg("上傳文件數量：【" + obj.total + "】張，上傳成功：【" + obj.successful + "】張，失敗：【" + obj.aborted + "】", {
time: 3000
});
console.log(obj.total); //得到總文件數
console.log(obj.successful); //請求成功的文件數
console.log(obj.aborted); //請求失敗的文件數
},
error: function(index, upload) {
var tr = demoListView.find('tr#upload-' + index),
tds = tr.children();
tds.eq(2).html('<span style="color: #FF5722;">上傳失敗</span>');
tds.eq(4).find('.demo-reload').removeClass('layui-hide'); //顯示重傳
}
});
});
</script>
後端代碼
public function uploadAction(){
$file=$_FILES['file'];
$root_url = 'uploadfiles/pic/image/';
if (!is_uploaded_file($file['tmp_name'])){
$data = array('code'=>1,'msg'=>"錯誤");
exit(json_encode($data,0));
}
/* $root_url.=date('Ymd').'/';*/
$ext = pathinfo($file['name']);
$num=makenum($this->memberinfo['id']);
$root_url.=$num.'/';
if (!is_dir($root_url)) {
mkdir($root_url,0777, true);
}
$pa=file_list::get_file_list($root_url);
$na=count($pa) + 1;
if ($na<10){
$name=$num.'-000'.$na;
}elseif($na<100){
$name=$num.'-00'.$na;
}elseif($na<1000){
$name=$num.'-0'.$na;
}else{
$name=$num.'-'.$na;
}
$n=$root_url.$name.".".$ext['extension'];
$result=move_uploaded_file($file['tmp_name'],$n);
if ($result){
exit(json_encode(array("code"=>0,"msg"=>"ok","file"=>$n,"size"=>$file['size']),0));
}else{
exit(json_encode(array("code"=>1,"msg"=>"false","file"=>$n,"size"=>$file['size']),0));
}
}
