TCPDF / FPDF-проблема разрыва страницы
Я пытаюсь создать PDF-файл с таблицей данных.. Но когда разрыв страницы выполняется, он переходит на новую страницу каждый раз, когда новая многоячеечная ячейка добавляется на страницу на уровне точки разрыва..!?
Я попытался сделать то же самое с TCPDF, но все та же проблема с разрывом страницы каждый раз, когда новая ячейка я добавил вокруг уровня точки разрыва страницы...
пример:

проблема в том, что в Cell() метод (который вызывается в MultiCell()) FPDF всегда добавляет новую страницу, если текущая позиция Y + высота новой ячейки больше разрешенной высоты страницы.
высота страницы по умолчанию, кажется, 297, с SetAutoPageBreak() вы substract 150 от него. Так когда Y + cell_height более graeter чем 147 вы всегда получаете новую страницу при вызове вашего cnstr_cell().
чтобы предотвратить это, вам нужно позвонить AddPage() самостоятельно. Добавьте этот чек в свой add_product() способ:
$x = $this->width;
$y = $this->pdf->GetY();
if (($y + $this->line_height) >= 147) {
$this->pdf->AddPage();
$y = 0; // should be your top margin
}
кстати. Мне также пришлось создать динамический PDF недавно, я закончил с помощью wkhtmltopdf, это было намного проще в использовании и настройке, чем все библиотеки PHP. Я предлагаю взглянуть на него.
