Система лайков / работа с MySQL / PHP

AlexMax13 · November 18, 2020

Решил продолжить тему Нравится +1, но зайти с другой стороны.

Хочу сделать Мне нравится со счетчиком. По аналогии как вк. Планирую использовать существующее поле в БД ISBN https://prnt.sc/vlmjgs

Изначально при создании товара буду вводить в это поле 0, либо сделаю чтобы автоматом проставлялось если поле пустое пустое.

Теперь нужно чтобы при клике на <button class="like">Like</button> добавлялось +1 в БД нужного продукта. Например этого: https://prnt.sc/vlmlzc

Загвоздка в том, чтобы добавить значение +1 именно нужному продукту. Например, находясь в каталоге или на странице товара, брать ид продукта и при клике на кнопку просто добавлять +1 в таблицу oc_product Столбец ISBN нужного ID товара. Прошу помочь.

А в чем проблема?

Основная проблема - система накруток - нужно остановить накруттку, не позволить дважды лайкнуть

Основная проблема - система накруток - нужно остановить накруттку, не позволить дважды лайкнуть

1. Проблема в том что я не знаю какой запрос нужен в БД. Имхо, не силен в этом. Если бы просто в БД поменять конкретное значение, то это не проблема. Но поменять значение нужного ID товара, пока мне не по силам. Поэтому спрашиваю, вдруг кто подскажет.

2. Проблему накруток уже постараюсь сам решить, т.е. ранее уже делал подобное с помощью куков. Но если есть что то получше - готов выслушать)

Пример того что нужно:
1. Есть кнопка со счетчиком на странице товара id54 (естественно что на каждой странице товара ид уникален):

<button id="like<?php echo $module_id; ?>">Like</button>
<span id="like_counter<?php echo $module_id; ?>"><?php echo $isbn; ?></span>

2. Нужно чтобы кликнув по этой кнопке, система отправляла в БД запрос на смену значения столбца ISBN https://prnt.sc/vln3ws Чтобы добавляло +1, желательно без перезагрузки страницы)

Вот и все.

Вот и я сел на этой задаче) Казалось бы обычная функция, но не тут то было(((

ocdev_pro · November 18, 2020

@AlexMax13 Нужно примерно так
1.Обновите таблицу product, для поля isbn измените тип данных на INT с длинной 11

ALTER TABLE `oc_product` CHANGE COLUMN `isbn` `isbn` INT(11) NOT NULL DEFAULT 0 COLLATE 'utf8_general_ci' AFTER `jan`;

2. Создайте метод в своем контроллере (вероятно product) метод setLike($product_id) который примет id товара и пошлет его в модель
3. в модели создайте метод updateLike($product_id) и таким запросом обновляется лайк при обращении к методу

	public function updateLike($product_id) {
		$this->db->query("UPDATE " . DB_PREFIX . "product SET isbn = (isbn + 1) WHERE product_id = '" . (int)$product_id . "'");
	}

4. в верстке создайте кнопку

<button class="btn btn-default" onclick="addLike(_<?php echo $result['product_id']; ?>);">Like <i class="fa fa-heart"></i></button>
<span class="like_count"><?php echo $result['isbn']; ?></span>

5. в своем javascript (вероятно в common.js)
добавьте функцию addLike(product_id) которая будет срабатывать при клике на кнопку

function addLike (id) {
  var product_id = id;
    
  $.ajax({
      url: 'index.php?route=product/product/setLike', //шлем id товара в метод для добавления лайка
      type: 'post',
      data: 'product_id=' + product_id,
      dataType: 'json',
      beforeSend: function () {
        //чет делаете с кнопкой, отключаете возможно
      },
      complete: function () {
        //чет делаете с кнопкой, Включаете возможно
      },
      success: function (json) {
        $('.alert').remove();

        if (json['success']) {
          //Если ваш метод вернул текущее кол-во лайков, здесь нужно обновить кол-во лайков
          $('#like_' + product_id).find('.like_count').html(json['count']);
        }
      },
      error: function (xhr, ajaxOptions, thrownError) {
        alert(thrownError + '\r\n' + xhr.statusText + '\r\n' + xhr.responseText);
      },
    });
}

Ну как-то так...

Конечно нужно проработать логику в контроллере, а еще возможно для борьбы с накруткой делать это все только для зарегистрированных пользователей.. но тогда и отдельная таблица для хранения данных и связей нужна.

Благодарю за ответ) Можно пример такой функции?

chukcha · November 19, 2020

public function setLike() {

$this->load->model('my_model')
$this->model->my_model->setLike($this->request->post['product_id']);
}

Прихований текст

1 годину назад, chukcha сказав:

public function setLike() {

Также поменял в бд тип поля как писал об этом ранее ocdev_pro https://prnt.sc/vm3nhs

Со значением по умолчанию действительно проще)

Результат на данный момент: https://prnt.sc/vm3q4i

Надо смотреть, это уже детали реализации, судьба которых в Ваших руках.

За Вас код можно писать только за деньги)

Если работаете напрямую с базой и сами пишете код своими руками, то почему бы не создать отдельное поле like вместо использования isbn?

Через месяц-другой будет намного понятнее въезжать что там понаписано. Равно как и другому разработчику будет проще понимать код, если вдруг будет кто-что дописывать.
