Upload Multiple Codeigniter

I have a form for multiple image uploads using codeigniter:

<input type="file" name="files[]" id="filer_input2" multiple>

And PHP:

#configuracoes base
$config['upload_path'] = $diretorio;
$config['allowed_types'] = 'gif|jpg|jpeg|png|pdf';
$config['remove_spaces'] = TRUE;
$config['encrypt_name'] = TRUE;
$config['max_size'] = '8192'; // 8Mbs


#inicia a biblioteca
$this->load->library('upload', $config);
$this->upload->initialize($config);


foreach($_FILES['files']['name'] as $valor){
    echo $valor."<br>"; 
}

But when trying to upload, it does not accept if there are several, it has to be one by one. As I upload multiple in codeigniter?

php codeigniter

  • Natively the class file Just one file, business is to use $_FILES in your case you missed the Dice and use a.

  • I don’t understand, the normal class only uploads.. but what suggests me to upload?

  • There’s this one lib that uploads multiple files based on the CI class, I have never used.

  • I posted a solution, I use it in my systems.

  • Okay, but how do I include her in the library?

  • Create a new file called files within the Libraries directory, paste the code, and use it as described.

Friend, I have a class for this purpose. Create a library in your project and add the class code.

class Files {

    private $Files        =   null;

    private $SaveTo       =   null;

    private $Length       =   null;        

    private $Response     =   array();

    private $Extensions   =   array();

    public function __construct( $files = '' ){

        $this->Files   =   $files;

    }


    public function setFile( $file ) {

        $this->Files   =   $file;

    }


    public function initialize( $dirToSave, $length, $fileExtension = array() ) {

        $this->SaveTo      =  $dirToSave;

        $this->Length      =  $length;

        $this->Extensions  =  $fileExtension;

    }

    public function processMultFiles() {

        if( is_dir( $this->SaveTo ) ) {

            $countFiles   =   count( $this->Files['name'] );

            if( $countFiles > 0 ) {

                for ($i = 0; $i < $countFiles; $i++ ) { 

                    if( isset( $this->Files['name'][$i] ) && trim( $this->Files['name'][$i] ) != '' ) {

                        $extensao  =  strtolower( end( explode( '.', $this->Files['name'][$i] ) ) );

                        $length    =  $this->Files['size'][$i];

                        $name      =  $this->Files['name'][$i];

                        if( array_search($extensao, $this->Extensions ) === false ) {

                            $this->Response['status']   =   $name . ' - Arquivo não permitido';

For use:

    //Limite do tamanho máximo que a imagem deve ter

    //Extensões permitidas para os arquivos
    $fileExtension  =   array( 'jpg', 'jpeg', 'png' );

    //Inicializa os parametros necessários para upload da imagem
    $this->files->initialize( $dirToSave, $length, $fileExtension );

    //Verifica se alguma imagem foi selecionada
    $image         =   isset( $_FILES[ 'image' ] ) ? $_FILES[ 'image' ] : null;
    if( !is_null( $image ) ) {

        //Seta o arquivo para upload
        $this->files->setFile( $image );

        //Processa o arquivo e recebe o retorno
        $upload  =   $this->files->processMultFiles();

        //Verifica retornbou algum código, se sim, ocorreu algum erro no upload
        isset( $upload['code'] ) ? 'mensagem de erro' : null;

        //Retorna o diretorio onde os arquivos foram salvos
        print_r( $upload );

    Reminder: Give write permission in the directory where images will be saved.

  • Message: Undefined Property: CI::$Files this error appears, as much as I have included the confrere file you said.

  • You are wrong, in this line : $this->Files->initialize( $dirToSave, $length, $fileExtension ), change to $this->files->initialize( $dirToSave, $length, $fileExtension ).

  • Returned the data in print_r, but did not send the image to the server... I checked the folder, it is correct!

  • It worked out, brother, thanks anyway!

  • What directory you passed in the parameter and what is your directory structure, where your codeigniter project is ?

  • Remember that the upload is based on your root directory, i.e., var/www/codeigniter. If you place Assets/image, the Assets, needs to be inside the codeigniter directory.

  • It was nothing, buddy. Enjoy.

The standard CI upload class does not allow sending multiple files, an alternative is this library and another is to use the $_FILES even.

$total = count($_FILES['files']['name']);

for($i=0; $i<$total;$i++){
   if(!move_uploaded_file($_FILES['files']['tmp_name'][$i], 'arquivos/novo_nome.jpg')){
      echo 'arquivo não importado';
   }
}

Remember to make a deal if you cannot upload.
