Boa Tarde

Estou desenvolvendo um projeto e me deparei com uma situação onde necessito salvar imagens em um diretório e o nome da imagem no banco de dados, porem quando realizo o uploads das imagens se elas estiverem com o mesmo nome uma substitui a outra. Como resolvo o problema? existem exemplos para resolver esse problema?

Grato

Você deve renomear a imagem antes de movê-la da pasta tmp para a pasta destino final.

<?php
if (isset($param['file'])) {
$source_file = 'tmp/'.$param['file'];
$dt = date('YmdH:m:s');
$file_name = $dt.'_'.param['file']); // acrescenta aaaammddhhmmss_<nome_arquivo>
$target_file = 'files/docs/' . $file_name;
if (file_exists($source_file))
{
// move to the target directory
rename($source_file, $target_file);
}
}
?>

Obrigado pela ajuda Marcelo; Mas eu ja tentei realizar um procedimento parecido mas sem resultado. Estou postando meu código se puderes me ajudar.

Você recebe o parâmetro em 2 lugares.
1) Linha 209 - você pode modificar o nome antes de atribuir à lista; ou
2) Linha 428 - quando você salva o arquivo que veio da lista.

Lembre-se de ajustar antes do "store".
