我使用精细的上传拖放功能上传多张图片。 所以我要求将关于上传图像的信息保存到数据库中：
将单个记录管理到数据库中，以便在上传后保存三种不同大小的单个图像的信息。例如：假设我找到了三个不同的图像 - image_thumbs.jpg，image_large.jpg，image_original.jpg < / strong>将存储在数据库中
1 | image_thumbs.jpg | image_large.jpg | image_original.jpg
所以我已经在服务器端设置逻辑以获得图像 qqparentuuid 如果它是子图像/ blob，如果它是父母那么得到 qquuid ，基于UUID（qqparentuuid / qquuid）我从上传的图片得到的，检查数据库是否存在UUID（qqparentuuid / qquuid）然后用当前图像名称更新记录，否则将新记录插入到具有受尊重的UUID（qqparentuuid / qquuid）的数据库中。
此逻辑工作正常但在少数情况下此逻辑失败，因为上传的文件在服务器上并行上传，有时会在数据库中创建三个或两个不同的行。根据我的观点，当文件在服务器上并行而不是按顺序并且所有逻辑都被触发时，就会发生这种情况。
我无法弄清楚，这是上传者的问题还是我的最终问题。我在下面分享了我的服务器端逻辑：

Fineuploader逻辑：
$('#fine-uploader').fineUploader({
// debug: true,
autoUpload: true,
scaling: {
sizes: [{
name: "small",
maxSize: 150
}, {
name: "medium",
maxSize: 500
}]
},
request: {
endpoint: "Components/fineUploaderProxy.cfm?cfc=ImageDemo&functionName=UploadImages"
},
validation: {
allowedExtensions: ['jpeg', 'jpg', 'png', 'gif'],
},
text: {
uploadButton: 'Choose File'
}
})
.on('progress', function(event, id, name, uploadedBytes, totalBytes) {
//alert('Name-'+name+"uploadedBytes-" +uploadedBytes+"totalBytes-"+totalBytes);
})
.on('error', function(event, id, name, reason, responseJSON) {
alert('There was an error with the upload.' + reason);
})
.on('complete', function(event, id, name, responseJSON) {
if (responseJSON.success) {
if (responseJSON.HASERRORS == true) {
$('.qq-upload-success').hide();
alert(responseJSON.DATA.RETURNOUTPUT);
} else {
$('.qq-upload-success').hide();
if (responseJSON.IMAGESIZE == 'small') {
ProductObjList.push(responseJSON.PRODUCTID);
$('#outputImage').append('<li><a onclick="setArtDetailsURL(' + responseJSON.PRODUCTID + ');" class="thumbClass" id=' + responseJSON.PRODUCTID + '><img height="130" src="images/' + responseJSON.RETURNID + '" alt="" /></a></li>');
}
}
}
})
.on('allComplete', function(event, succeeded, failed) {
/* set final list of product after complete image upload*/
$('#productlist').val(ProductObjList.toString());
})
所以请建议。
