My question is simple, but I'm not finding an answer. I have a form with 5 fields, however all fields are required instead of I create empty () for each field, how would I check to see if all the fields are empty at one time?

php

You can check field by field with the function empty() and is_null() or compare the value with empty. But all at once can not.

I found this piece of code that can make it easier for you, I have not tested it.

// Cria as variáveis dinamicamente
foreach ( $_POST as $chave => $valor ) {
    // Remove todas as tags HTML
    // Remove os espaços em branco do valor
    $chave = trim( strip_tags( $valor ) );

    // Verifica se tem algum valor em branco
    if ( empty ( $valor ) ) {
        $erro = 'Existem campos em branco.';
    }
}
