CRIAR UM UPLOAD NUMA PAGINA EM PHP

[FAHHAM]

Bom Dia galera!!!


como todos já sabem sou novato e como linux não é windows e não posso apenas clicar no next.
tenho que pensar.

criei um fotolog em php, porém vendo a dificuldade dos usuário em enviar imagens para o diretório do fotolog
então gostaria de duas coisas:

1ª - como fazer um upload em uma pag php;
2ª - como fazer que a pagina aceite pré-visualizações em jpegs.

estou usando o PHP-PHOTO-GALLERY.


muito obrigados a todos pela compreensão e paciência.

[FAHHAM]

muito obrigado!!!

mas o que ocorre não é exatamente o uqe vc me forneceu, eu acho pois sou muito leigo no assunto php.


acesse a página : www.atlanticont.com.br/fotolog. então irá reparar que as miniaturas não aparecem, aparecem com formato de um X.

se isto te ajudar a me ajudar agradeço.

se puder me enviar a solução deste meu grande problema e com certeza pequeno para vcs, agradeço.

este e o arquivo de configuração

** $image = array( "image_1.gif", "image_1.jpg",
** "image_2.gif", "image_2.jpg",
** "image_3.gif", "image_3.jpg");
**
** [3] Automatically read your image directory
** Most work for PHP - easiest for you:
** LEAVE $image undefined (comment it out or delete it)
**
** Gif and jpg files must be named with ".gif" and ".jpg" extenstion (with lower case extenstion names)

um abraço

boa noite!!!

[flamehazard]

algumas imagens estão abrindo... tenta dar uma olhada nas extensões, php/linux são case sensitive...

http://img272.imageshack.us/img272/3867/img010tu.gif

[FAHHAM]

não sei se isso pode estar causando o erro. no diretório de armazenamento as imagens que não aparecem estão como jpegs e na propriedades da imagens na página aparece como gif.


será que o erro pode ser este.


valeu!!!


muito obrigado.

[edmafer]

Cara,

O seu erro é que ele não está encontrando as imagens. Verifique as permissões, pode ser que seja isto, pois algumas imagens estão funcionando.

[FAHHAM]

detalhe enorme que esqueci de falar, novato?!!?!?1?


no diretório as imagens estão com jpegs. e percebi que elas foram alteradas para gif na própria página.



valeu pela idéia de verificar as permissões. estarei vendo isto amanhã.


muito obrigado mesmo.
