首先抱歉我的英语不好;
我正在使用缩略图搜索带有图像的良好文件上传..
我找到了Krajee bootstrap-fileinput http://plugins.krajee.com/file-input
我认为,这是非常完整的。我已成功上传照片
这是我的代码:
$("#images").fileinput({
uploadUrl: strURL, // you must set a valid URL here else you will get an error
uploadAsync: true,
previewFileType: "image",
allowedFileExtensions: ["jpg", "gif", "png"],
allowedFileTypes: ["image"],
showUpload:true,
maxFileSize: 5000,
minFileCount: 1,
maxFileCount: 8,
elErrorContainer: "#errorBlock",
overwriteInitial: false,
initialPreview: [
"<img src='http://lorempixel.com/200/150/people/1'>",
"<img src='http://lorempixel.com/200/150/people/2'>",
],
initialPreviewShowDelete: true,
initialPreviewConfig: [
{caption: "People-1.jpg", width: "42px", url: "/site/file-delete", key: 1},
{caption: "People-2.jpg", width: "42px", url: "/site/file-delete", key: 2},
],
});
但现在,在上传照片后,我希望用户进行修改 (删除以前上传的照片,添加新的等等。)
所以,我必须使用initialPreview和initialPreviewConfig选项......
但我不知道如何在服务器端放置照片?
我需要使用服务器代码生成用于初始化文件输入的初始javascript
我试过了:
控制器(MVC)
$preview = array("<img src='<?php echo DIR;?>images/2015/Mars/100_3641.jpg' class='file-preview-image' >",
"<img src='<?php echo DIR;?>images/2015/Mars/100_3785.jpg' class='file-preview-image' >");
查看:
$("#images").fileinput({
uploadUrl: strURL, // you must set a valid URL here else you will get an error
uploadAsync: true,
......................
initialPreview: '<?php echo $preview; ?>' , // images from server ????
initialPreviewShowDelete: true,
....................................
});
但这不正确!!
我该怎么做?
非常感谢

制作Json数组
$json_preview = json_encode($preview);
$("#images").fileinput({
uploadUrl: strURL, // you must set a valid URL here else you will get an error
uploadAsync: true,
......................
initialPreview: <?php echo $json_preview; ?> , // images from server ????
initialPreviewShowDelete: true,
....................................
});
