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.

Answer 2

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);
}
