Jquerydagi kod

$(document).on("click", "#insert-product-form",function(){
    var data = new FormData();
    var form = $('#product-create-form').serializeArray();
    $.each(form, function (key, input) {
      data.append(input.name, input.value);
    });
    var file_data = $("#product-imagefile").prop("files")[0];   
    data.append("imageFile", file_data);
    console.log(data)
    $.ajax({
        url: '/product/create', 
        dataType: 'JSON',  
        type: 'post',
        data: data,
        contentType: false,
        processData: false,
        success: function(response){
            if (response.status == 'error') {
                $('#exampleModal .modal-title').html('Tovar qo\'shish').css({fontSize: 23})
                $('#exampleModal .modal-body').html(response.content)
            } else if (response.status == 'success') {
                $.pjax.reload('#id-pjax')
                $(".close").trigger("click");
            }
        }
     });
});

Ajax orqali file yuklanayotganda file malumotlari kelmay qoladi xattoki $_FILES o'zgaruvchisida ham shuning uchun manashu usulda malumotlarni saqlab olsa bo'ladi

yii2 paginatsiya xatoliklari $disabledListItemSubTagOptions = ['class'=>'page-link']; $linkContainerOptions = ['class' => 'page-item']; $linkOptions = ['class' => 'page-link']; bo`sh massivlarni shular bilan to`ldirish kerak

pagination xatoligini bunday tuzatish xato o'rniga gridviewni o'zida berib ketgan yaxshi birinchi usulda butun proyektga tasir qilib ketadi. Mana bunday
