PHP вставить фильтр и распечатать его на изображениях

Question

У меня есть эта раздражающая проблема, когда я пытаюсь добавить фильтр к изображению, которое я разместил.Фильтры изображений загружаются с помощью CSS-файла: CSSgram.css.В поле выбора указан правильный фильтр (опция html), и он получает его и правильно сохраняет в базе данных.Однако я не могу распечатать правильный фильтр на изображении, потому что есть ошибки в классе HTML, где следует добавить переменную php.

Фрагменты кода ниже:

Answer 1

Есть несколько способов справиться с этим. Я просто покажу ту, которую мне проще всего написать.

Для начала присвойте $filter значение по умолчанию (пустое), если оно не было выбрано.

$filter = (!empty($_POST['filter']) ? $_POST['filter'] : ''); //filter select

Затем, когда вы делаете вызов, чтобы получить и отобразить твиты, передайте выбранное значение фильтра (если оно есть).

<?php $getFromT->tweets($user_id, 10, $filter); ?>

Обновление tweets.php для принятия фильтра в качестве параметра функции tweets() (я также даю ему значение по умолчанию в определении функции на случай, если вы вызываете его из других мест).

public function tweets($user_id, $num, $filter = ''){

Наконец, используйте это переданное значение в качестве значения класса

<img src="'.$tweet->tweetImage.'" class="'.$filter.'" data-tweet="'.$tweet->tweetID.'"/>

Альтернативой может быть создание новой функции в вашем классе Tweet, которая называется что-то вроде setFilter($filter). Затем вы вызываете эту функцию в main.php, передавая выбранный фильтр, и обращаетесь к ней в вашем Tweet классе как $this->filter.
