Problemas Com Plugin Wordpress

johnlennonfs · Maio 29, 2010

Olá, primeiramente pesso desculpas caso tenha postado no local errado, uma vez que se trata de uma mistura de php com javascript creio eu...

oque acontece é que apos o upload da imagem da o seguinte erro:

PHP Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in E:\home\buffetghir\Web\wp-content\plugins\wp-photo-album\wppa.php on line 609

Quanto as premiçoes estao corretas uma vez que os thumbnails sao criados corretamente e as fotos ampliadas também.

Codigo do wppa.php

A mensagem diz que o Filename (nome do arquivo) não pode estar vazio. O erro é esse, a variável que contem o nome do arquivo enviado está vazia, e por isso dá esse erro.

johnlennonfs · Maio 29, 2010

...a questao é que o arquivo tem nome sim =/, o erro nao esta no php entao? pq caso seja F**** pra mim pq i hate javascript =/

André D. Molin · Maio 30, 2010

O arquivo tem nome sim, mas o problema é que esse nome não está chegando na função getimagesize().

ozorio silva · Maio 30, 2010

A função getimagesize() irá determinar o tamanho de qualquer arquivo de imagem GIF, JPG, PNG, SWF, SWC, PSD, TIFF, BMP, IFF, JP2, JPX, JB2, JPC, XBM, ou WBMP e retornar as dimensões juntamente com o tipo de arquivo e a altura/largura para usar dentro de uma tag HTML IMG.

Nota: Suporte para JPC, JP2, JPX, JB2, XBM, e WBMP tornou-se disponível no PHP 4.3.2. Supporte para SWC a partir do PHP 4.3.0.

Retorna uma matriz com 4 elementos. O índice 0 contém a largura da imagem em pixels. O índice 1 contém a altura. O índice 2 é uma indicação do tipo de imagem: 1 = GIF, 2 = JPG, 3 = PNG, 4 = SWF, 5 = PSD, 6 = BMP, 7 = TIFF(intel byte order), 8 = TIFF(motorola byte order), 9 = JPC, 10 = JP2, 11 = JPX, 12 = JB2, 13 = SWC, 14 = IFF, 15 = WBMP, 16 = XBM. Estes valores correspondem as constantes IMAGETYPE que foram adicionadas no PHP 4.3. O índice 3 é uma string com o height="yyy" width="xxx" correto que pode ser usado diretamente numa tag IMG.

Se for impossível acessar a imagem filename, ou não for uma imagem válida, getimagesize() irá retornar FALSE e gerar um warning.

teu erro

bom se a variavel estiver vazia sempre vai dar este erro

verifica se ela exixte com isset e tenta impimi ela quando tu enviar para ver se ela aparece ok

Nada =/ nao imprimiu, continuou no mesmo erro, apenas mudou a linha é claro =/

OK entao, a variavel é nula?

Ta, em termos de gambiarra eu soh teria que fazer esse erro maldito sumir, mas...em termos de que não é pra mim eu deveria arrumar...oq me dizem?
