Sorry if it got too strange the question, I have a system that when the user upload has no image it puts in the following img directory:
/xxxx/estatico/comuns/sem_imagem/
My idea was to generate an index.php in this directory that generated the image, is this method correct, or would it use server resources in vain? I have an average of 2000 hits per day.
Here is a very general example of what you want to do
Well you can create a function
Suppose you are receiving your upload data via $ _POST
function QualImagemUsar(){
if(isset($_POST['variaveldaImage']){
$caminhoDaImagem = "pasta/imagensUsuarios/iamgemQueUsarioEnviouEVcSalvou.jpg";
}else{
$caminhoDaImagem = "pasta/imagensUsuarios/imagemGenerica.jpg";
}
return $caminhoDaImagem ;
}
In your html
<img src="<?php echo QualImagemUsar(); ?>">
I think it's what you want a function that verifies if the image was sent
or if you want to check if the image exists in the directory use
if(file_exists("diretori/arquivo.jpg")
