在bootstrap-fileinput中通过post发送一个额外的变量

Question

How to send an extra variable to php by post in bootstrap-fileinput.

I have added the css and js in my web,and here is my html:

<input name="uploadfile" id="input-id" type="file" multiple class="file" data-preview-file-type="text">

This is my script:

$('#input-id').fileinput({
    language: 'en',
    uploadUrl: 'upload?path=/',
    maxFileCount: 5,
    // allowedFileExtensions : ['any'],
});

it's the variable
path = '/'

You should use uploadExtraData, as in:

$('#input-id').fileinput({
    language: 'en',
    uploadUrl: 'upload?path=/',
    maxFileCount: 5,
    // allowedFileExtensions : ['any'],
    uploadExtraData: function() {
        return {
            foo: "bar"
        };
    }
});
