- Pessoal é o seguinte, sou novo na linguagem PHP e me deparei com um problema, tenho uma área de registro com os seguintes campos: Título e Comentário, onde o titulo é um campo Imput e o Comentário é um campo Textarea, para gravar os dados na sql e exibir os resultados tranquilo mas quando vou para a página de editar os dados, o texto do campo Textarea não aparece.
- Por favor, alguém sabe como resolver isso, pois quero prosseguir em meu aprendizado, Obrigado.

O elemento <textarea> não possui o atributo value. O valor é inserido entre <textarea> e </textarea>. Sinto muito em lhe dizer, mas o doctype XHTML Strict em teu código não passa de enfeite.
