ajaxfileUpload ajax 上传图片使用

前台html:

<div class="b-mg15 img-text" room_id="<?= $items['id'] ?>">
<a class="modal-get">
<img <?php if ($items['room_image']) {
$url = Url::to('@web' . '/' . $items['room_image']);
echo 'src' . '=' . $url;
} ?> id="room_image">
</a>
<div class="pull-txt upload_image"
room_id="<?= $items['id'] ?>" <?php if ($items['room_image']) echo "style=\"display: none\"" ?>>
<div class="b-mg15 t-mg60">
<span class="glyphicon glyphicon-user f50">
</span>
</div>
<a class="">
点击上传会议室图片
</a>
</div>

js代码：

$(".img-text").click(function () {
$("#fileToUpload").click();
$("#fileToUpload").attr('room_id', $(this).attr('room_id'));
});
//选择文件之后执行上传
$('#fileToUpload').on('change', function () {
$.ajaxFileUpload({
url: "<?=Url::toRoute('ajax-upload')?>",
secureuri: false,
fileElementId: 'fileToUpload',//file标签的id
dataType: 'json',//返回数据的类型
data: {_csrf: "<?=Yii::$app->request->getCsrfToken()?>", room_id: $(this).attr('room_id')},//一同上传的数据
success: function (data) {
//把图片替换
$("#room_image").attr('src', data.result);
window.location.reload();
},
error: function (data, status, e) {
alert(e);
}
});
});

后台 php 代码：

/**
* ajax 上传图片
* @return string
*/
public function actionAjaxUpload()
{
return json_encode(MeetRoomService::AjaxUploadImage());
}

/**
* ajax 上传图片
* @return string
*/
public static function AjaxUploadImage()
{
$returnData = [];
$company_id = Yii::$app->company->getId();
$room_id = Yii::$app->request->post('room_id','');
$room = MeetRooms::find()->where(['id'=>$room_id])->one();
$typeArr = array("jpg", "png", "gif");//允许上传文件格式
$path = 'meetRoomImg/' . $company_id.'/';
$dirPath = 'meetRoomImg';
if(!file_exists($dirPath))
{
mkdir($dirPath, 0777);
chmod($dirPath, 0777);
}
if (!file_exists($path)) {

mkdir($path, 0777);
chmod($path, 0777);
}
if (isset($_POST)) {
$name = $_FILES['upfile']['name'];
$size = $_FILES['upfile']['size'];
$name_tmp = $_FILES['upfile']['tmp_name'];
if (empty($name)) {
$returnData['error'] = '您还未选择图片';
$returnData['code'] = 400;
return $returnData;
}
$type = strtolower(substr(strrchr($name, '.'), 1)); //获取文件类型
if (!in_array($type, $typeArr)) {
$returnData['error'] = '请上传jpg,png或gif类型的图片！';
$returnData['code'] = 400;
return $returnData;
}
if ($size > (5000 * 1024)) {
$returnData['error'] = '图片大小已超过5000KB';
$returnData['code'] = 400;
return $returnData;
}
$yCode = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J');
$orderSn = $yCode[intval(date('Y')) - 2011] . strtoupper(dechex(date('m'))) . date('d') . substr(time(), -5) . substr(microtime(), 2, 5) . sprintf('%02d', rand(0, 99));
$pic_url = $path . '/' . date('Y-m-d') . $orderSn . '.' .$type;
$pic_name = date('Y-m-d') . $orderSn . '.' .$type;
if (move_uploaded_file($name_tmp, $pic_url)) { //临时文件转移到目标文件夹
$room->room_image = $pic_url;
$room->save(false);
$returnData['error'] = '0';
$returnData['result'] = $pic_url;
$returnData['code'] = 200;
} else {
$returnData['error'] = '上传有误，清检查服务器配置！';
$returnData['code'] = 400;
}
return $returnData;
}
}

注意问题：

上传成功之后没有执行回调函数。

打开ajaxfileupload.js拉到底下找到

[javascript] view plain copy
if ( type == "json" ) {
eval( "data = " + data );
}

改成：
[javascript] view plain copy
if ( type == "json" ) {
data = data.replace("<pre>","").replace("</pre>","");
//data = eval("("+data.replace("<pre>","").replace("</pre>","")+")");
