blz?!
seguinte.. peguei um script php que lista os arquivos e pastas de um determinado local no servidor e cria um link para download ou navegação... Adaptei o script ao site que estou desenvolvendo, acrescentei várias modificações, criei o layout e pá.. agora que vou lançar o sistema ao publico, descubro que o script está com um problema que não consigo, por nada, resolver...
é o seguinte:
no script original, se as pastas ou arquivos tivessem espaços e/ou acentuações, o link quebrava, pois o código gerava um link com o nome real do arquivo ou pasta:
$files_links_array[$key] = '<a href="'.$dir_to_browse_original.$folder."/".$val.'">'.$val."</a>
para solucionar este problema, eu alterei o código para que ele codificasse os nomes para o formato rawurlencode:
$files_links_array[$key] = '<a href="'.$dir_to_browse_original.rawurlencode($folder)."/".rawurlencode($val).'">'.$val."</a>
beleza!! isto resolveu todos os problemas de acesso as pastas ou download dos arquivos que tivessem acentos e etc... mas, em contrapartida, agora, todos os links darquivos dentro de "sub-sub-pastas" são gerados errados, pois, no lugar da " / " no endereço do link, é colocado o código referente a barra " %2F "
isto só acontece na segunda subpasta... veja o exemplo dos links gerados para um mesmo arquivo em diferentes pastas:
Pasta raiz: http://gabrielbueno....eno/arquivo.doc
Subpasta 1: http://gabrielbueno....201/arquivo.doc
Subpasta 1-2: http://gabrielbueno......no/subpasta 1%2Fsubpasta2/arquivo.doc
Como eu posso solucionar este problema sem que eu tenha que tirar o rawurencode?!
o codigo completo segue:
