Lara Marques Posted April 21, 2020 at 02:38 PM Report Share #617909 Posted April 21, 2020 at 02:38 PM Boa tarde eu estou a fazer uma confirmação de email e palavra-passe com ligação a base de dados. O que eu queria fazer era quando o email ou a palavra passe não são encontrados que diga essa mesma frase por abaixo dos botões de login e cancelar e o que ele está a fazer é dar essa frase noutra página. Acham que me podiam ajudar?
