Сообщение php, ошибка, пожалуйста, предложите изменение

Question

Это мой код моего файла status.php, но при статусе публикации он показывает только одно, например, type_unknown, но я не уверен, почему он не работает должным образом. и type_unknown также является командой в этом кодировании, пройдите эту команду и после этого предложите любое изменение, которое вы хотите.

Answer 1

Если проблема появляется в этой строке:

if($_POST['type'] != "a" || $_POST['type'] != "c"){ 

Тогда это означает, что у вас нет формы ввода с именем type внутри него, или пост данные не могут быть переданы вообще. Итак, проверьте свою форму HTML, если она имеет входной код type

Answer 2

Проблема заключается в логике условного выражения. Если вы измените это значение на:

if($_POST['type'] != "a" && $_POST['type'] != "c") 

тогда условное состояние должно работать должным образом. Обратите внимание, что изменение изменяет значение '||' до '& &'.

Зачем это редактировать? Предположим, что: $ _POST ['type'] == "a". Если это так, то:

$_POST['type'] != "a" // false 
$_POST['type'] != "c" // true 

Таким образом, условные принимает значение: если (ложь || истинно), что в свою очередь имеет значение, если (истина). Единственный раз, когда исходная логика будет работать, - это $ _POST ['type']! = "A" AND $ _POST ['type']! = "C" (чего не может быть, потому что для нее требуется, чтобы одна и та же переменная имела две значения в одно и то же время).
