I have a function in PHP to add a thumbnail image as a course cover on my website, regardless of the image having the right requirements, is returned the message:

Thumbnail image exceeds the maximum size of 1MB allowed.

I wonder what’s wrong with the code below:

function usuarios_cursos_miniatura_atualiza()
{
    if ($this->site_model->checa_logado_usuario()) {
        $data = str_replace('"', "'", $_POST);
        $info['list8'] = $this->site_model->checa_logado_usuario();
        $data['usuarios_id_fk'] = $info['list8']['usuarios_id'];
        $data['cedoc_doc_id_fk'] = $this->site_model->dono_curso($data['usuarios_id_fk'], $data['cedoc_doc_id_fk']);
        if ($data['cedoc_doc_id_fk']) {
            if ($_FILES['imagem']['name'] <> NULL) {
                $file_name = $_FILES['imagem']['name'];
                $file_extension = explode(".", $file_name);
                $file_extension = $file_extension[count($file_extension) - 1];
                $file_extension = strtolower($file_extension);
                if (($file_extension == 'jpg') || ($file_extension == 'jpeg') || ($file_extension == 'png') || ($file_extension == 'gif')) {
                    // FAZ UPLOAD DA IMAGEM
                    $config['upload_path'] = './uploads/_images/cedoc_doc_' . $data['cedoc_doc_id_fk'];

You should separate this code into smaller and more specific functions. It improves readability and makes it easier to understand what’s going on. Those ifs nested are complicated to understand.

I didn’t develop it.

Yes, it’s in the picture.

I think your problem is here: $config['max_size'] = '1000';. Switch to x or take it out of this line to make it unlimited. I don’t know much about php. But I think that’s it.

This happens because the maximum allowed value for the file size in the key max_size of array $config is smaller than the image size:

$config['max_size'] = '1000';

You must define this property with a value in Kilobytes according to the documentation, then the right thing would be:

$config['max_size'] = '1024'; // 1 MB

Updating: The problem was occurring because the directory did not exist before specifying the directory in the upload, check if it exists:

if (($file_extension == 'jpg') || ($file_extension == 'jpeg') || 
   ($file_extension == 'png')  || ($file_extension == 'gif')) {
    ....
    $diretorio = './uploads/_images/cedoc_doc_' . $data['cedoc_doc_id_fk']; 
    if (!file_exists($diretorio)) {     
        mkdir($diretorio, 0777, true); 
    }
    $config['upload_path'] = $diretorio;
    ....
    ..
