Я пишу плагин фильтраций тегов для wordpress но почему то у меня появляется ошибка
Fatal error: Cannot redeclare exc_post() (previously declared in C:\xampp\htdocs\wor\wp-content\plugins\GOG11\GOG11.php:64) in C:\xampp\htdocs\wor\wp-content\plugins\GOG11\GOG11.php on line 141
На строке
if ($_SESSION['filter2'] == ''){
И самое любопытное то что на точно такой же строке только
if ($_SESSION['filter1'] == ''){
Ошибки нету
И она возникает только когда ['filter2'] == '' при всех остальных значениях все работает нормально
Если вместо пропуска я указываю 1 то ошибка появляется уже на filter4 перескакивая filter3
Вот весь код плагина
session_start();
if ($_POST['filter1']){
$_SESSION['filter1'] = $_POST['filter1'];
}

$_SESSION['filter2'] = $_POST['filter2'];
