Answer 1

字段名称应该用单引号引起来。

 'files[]':
    {
         required: true,
    }

和

 'files[]':
    {
        required: 'Please Upload Image or Video.'
    }

您的代码应类似于

$("#GallaryForm").validate({
    rules: {
        event_id: {
            required: true, // <-- this comma is not required
        },
        'files[]': {
            required: true, // <-- this comma is not required
        },   // <-- this comma is not required
    },
    messages: {
        event_id: {
            required: 'Please Select Event .', // <-- this comma is not required
        },
        'files[]': {
            required: 'Please Upload Image or Video.', // <-- this comma is not required
        }, // <-- this comma is not required
    }, // <-- this comma is not required
});

您应该在单引号中加上元素的名称，以在jquery验证中应用规则和消息

$("#GallaryForm").validate({
    rules: {
        event_id: {
            required: true,
        },
        'files[]': {
            required: true,
        },
    },
    messages: {
        event_id: {
            required: 'Please Select Event .',
        },
        'files[]': {
            required: 'Please Upload Image or Video.',
        },
    },
});
