Problema em alterar nome ficheiro no upload

Drumente · Março 20, 2012

Olá a todos!

Eu coloquei 1 plugin no meu wordpress chamado Upload+ que altera o nome do ficheiro e salva consoante a opção que escolher nas opções do plugin.

Estou a tentar fazer 1 nova opção em que o nome do ficheiro será alterado para o que se escrever, quando se cria 1 novo tópico, no titulo.

Ao fazer o upload do ficheiro, quando mostrar o ficheiro, o seu nome aparecerá diferente.

O meu problema é que não consigo obter o ID do tópico.

Já tentei usar:

[/color]

[color="#2e3436"]<?php[/color]

[color="#2e3436"]global $post;

$post = get_post($post);

$title = $post->post_title;

Mas se fizer assim, sabendo o numero do post:

<?php

$post = 151;

$post = get_post($post);

$title = $post->post_title;

?>

Já consigo obter o que foi escrito no titulo e mudar o nome do ficheiro para ex: titulo.jpg

Será que tenho que mandar como parametro de uma função ou o que será que estou a fazer mal?

Aqui vai o código para poderem ver.

Obrigado!
