I want to delete a BD record that contains an image. When you do this, also delete that image from the folder where it is. How to proceed to make such action?

The helper of files from Codeigniter allows you to delete files in a given path:
$this->load->helper("file");
delete_files($caminho);
If you want to delete only one file, you will be better served using the function unlink() of PHP:
$caminhoParaFicheiro = '/caminho/para/ficheiro/bubu.jpg';
if (unlink($caminhoParaFicheiro)) {
echo 'Bubu morreu';
}
else {
echo 'Não foi possível matar o BuBu';
}
How can you call the unlink function of PHP:

You understand its logic. But the image deletion is done through a record list, where I will have the button to perform such action. How could I proceed?

To delete only one file:
<?php
$file = '/dir/src/arquivo.png';
if(unlink($file)){
echo 'Excluido com sucesso';
}else{
echo 'Erro ao excluir';
}
?>
To delete multiple files:
<?php
$dir = '/dir/src/'; //Irá excluir todos do diretório src
$open = opendir($dir);
while($read = readdir($open)){
if($read != '.' && $read != '..'){
$e = @unlink($dir.$read);
if($e){
echo 'Arquivo {$read} excluido com sucesso <br>';
}else{
echo 'Erro ao excluir o arquivo {$read} <br>';
}
}
}
?>

Your question talks about one thing, but your code mirrors another. Specifically, what do you want to do is delete a file when you delete a comic book entry or delete the "recipes" directory? With your code you have now entered in the question, you are deleting the folder and not a file within it. Regarding the error you get, it is a lack of permissions in the folder to delete it, probably the user who created it is not trying to delete it.

Sorry for my mistakes. I edited the question, I think I could clarify more, otherwise, sorry again!
