php - Carga de múltiples imágenes con CodeIgniter

file-upload

Question

Soy un usuario nuevo para usar el encendedor de código en mi proyecto, me enfrento a un problema al cargar varios archivos, pero el último solo se inserta en todas las imágenes del campo de tres imágenes.

mi controlador es:

function products()
    {
     date_default_timezone_set("Asia/Kolkata");
     $config[''upload_path''] = ''./resources/images/products/'';
     $config[''allowed_types'']        = ''gif|jpg|png'';
     $config[''max_size'']             = 1000;
     $config[''max_width'']            = 1024;
     $config[''max_height'']           = 768;
     $this->load->library(''upload'', $config);
     $this->upload->do_upload(''userfile'');
        $data = array(''prod_image'' => $this->upload->data(), 
             ''prod_image1'' => $this->upload->data(),
              ''prod_image2'' => $this->upload->data());
    $product_image=$data[''prod_image''][''file_name'']; 
    $product_image1=$data[''prod_image1''][''file_name''];
    $product_image2=$data[''prod_image2''][''file_name''];

        $data = array(
                ''name'' => $this->input->post(''pd_name''),
                ''prod_image'' => $product_image,
                ''prod_image1'' => $product_image1,
                ''prod_image2'' => $product_image2,
                ''created_time'' => date(''Y-m-d H:i:s''));

        // insert form data into database
        $result_set= $this->tbl_products_model->insertUser($data);

    }       

mi punto de vista es:

<input class="form-control" name="pd_name"type="text"/>
<input type="file"  class="file_upload2" name="userfile"/> //1
<input type="file" class="file_upload2" name="userfile"/> //2
<input type="file" class="file_upload2" name="userfile"/>//3

Por favor, ayuda cómo insertar 3 imágenes.

mi base de datos como

===========================================
id|name|prod_image|prod_image1|prod_image2|
===========================================
 1|ard|           |           |          |
============================================

Answer 1

El problema es con la siguiente línea de código:

<input type="file"  class="file_upload2" name="userfile"/> //1
<input type="file" class="file_upload2" name="userfile"/> //2
<input type="file" class="file_upload2" name="userfile"/>//3

Estos tres tienen el mismo nombre.

Para resolver esto hay dos formas:

Dar nombre diff a los 3 archivos de tipo de entrada

Haga que un único archivo de tipo de entrada con su selección de archivos múltiples sea verdadero y su nombre debe ser una matriz como:

<input type="file" name="filefield[]" multiple="multiple">

Realice los siguientes cambios e intente nuevamente.

HTML:

<input type="file" name="userfile[]" multiple="multiple">

PHP:

<?php
public function products()
{       
    $this->load->library(''upload'');
    $dataInfo = array();
    $files = $_FILES;
    $cpt = count($_FILES[''userfile''][''name'']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES[''userfile''][''name'']= $files[''userfile''][''name''][$i];
        $_FILES[''userfile''][''type'']= $files[''userfile''][''type''][$i];
        $_FILES[''userfile''][''tmp_name'']= $files[''userfile''][''tmp_name''][$i];
        $_FILES[''userfile''][''error'']= $files[''userfile''][''error''][$i];
        $_FILES[''userfile''][''size'']= $files[''userfile''][''size''][$i];    

        $this->upload->initialize($this->set_upload_options());
        $this->upload->do_upload();
        $dataInfo[] = $this->upload->data();
    }

    $data = array(
        ''name'' => $this->input->post(''pd_name''),
        ''prod_image'' => $dataInfo[0][''file_name''],
        ''prod_image1'' => $dataInfo[1][''file_name''],
        ''prod_image2'' => $dataInfo[2][''file_name''],
        ''created_time'' => date(''Y-m-d H:i:s'')
     );
     $result_set = $this->tbl_products_model->insertUser($data);
}

private function set_upload_options()
{   
    //upload an image options
    $config = array();
    $config[''upload_path''] = ''./resources/images/products/'';
    $config[''allowed_types''] = ''gif|jpg|png'';
    $config[''max_size'']      = ''0'';
    $config[''overwrite'']     = FALSE;

    return $config;
}
?>

Answer 3

Varios archivos cargan archivos ilimitados

Los nombres de columna de la tabla de base de datos ( profile_images ) son image_name (255, varcher) , Added_datetime (marca de tiempo actual)

Ver

<?php echo validation_errors();?>
<?php echo form_open_multipart(''pages/multiple_files'');?>
<p><input type="file" multiple="multiple" name="image_name[]" class="form-control" /></p>

<input type="submit" class="btn btn-success btn-block"/> 
</form>

Controlador

public function multiple_files(){
  $this->load->library(''upload'');
  $image = array();
  $ImageCount = count($_FILES[''image_name''][''name'']);
        for($i = 0; $i < $ImageCount; $i++){
            $_FILES[''file''][''name'']       = $_FILES[''image_name''][''name''][$i];
            $_FILES[''file''][''type'']       = $_FILES[''image_name''][''type''][$i];
            $_FILES[''file''][''tmp_name'']   = $_FILES[''image_name''][''tmp_name''][$i];
            $_FILES[''file''][''error'']      = $_FILES[''image_name''][''error''][$i];
            $_FILES[''file''][''size'']       = $_FILES[''image_name''][''size''][$i];

            // File upload configuration
            $uploadPath = ''./assets/images/profiles/'';
            $config[''upload_path''] = $uploadPath;
            $config[''allowed_types''] = ''jpg|jpeg|png|gif'';

            // Load and initialize upload library
            $this->load->library(''upload'', $config);
            $this->upload->initialize($config);

            // Upload file to server
            if($this->upload->do_upload(''file'')){
                // Uploaded file data
                $imageData = $this->upload->data();
                 $uploadImgData[$i][''image_name''] = $imageData[''file_name''];

            }
        }
         if(!empty($uploadImgData)){
            // Insert files data into the database
            $this->pages_model->multiple_images($uploadImgData);              
        }
  }

Modelo

  public function multiple_images($image = array()){

     return $this->db->insert_batch(''profile_images'',$image);
             }
