I have used some code I found before to upload 1 image at a time and this works perfect. I would like to use the same style of code but for multiple images.
The Model:
function cover_upload($afbeelding) {
// path where the picture needs to be uploaded
echo $album_path = APPPATH . 'images/covers';
// configuration for the upload
$ext = end(explode(".", $_FILES['userfile']['name']));
$config = array(
'file_name' => $afbeelding . '.' . $ext,
'upload_path' => $album_path,
'allowed_types' => 'gif|jpg|jpeg|png',
'max_size' => '5120'
);
// load upload library with the configuration
$this->load->library('upload', $config);
// upload picture with the upload library
if (!$this->upload->do_upload()) {
echo $this->upload->display_errors();
die();
}
// get data array of the uploaded picture
$image_data = $this->upload->data();
// configuration for the picture thumbnail resize
echo $image_data['full_path'];
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => realpath($album_path . '/thumb'),
'maintain_ration' => TRUE,
'width' => 300,
'height' => 300
);
// load image manupulation library with the configuration
$this->load->library('image_lib', $config);
// resize picture
$this->image_lib->resize();
$this->image_lib->clear();
// submit file name of the uploaded picture to save it in the database
$bestandsnaam = $image_data['file_name'];
return $bestandsnaam;
}
the view (just the part about the image):
<div class="form-group">
<label class="col-sm-2 control-label" for="CoverFoto">picture</label>
<div class="col-sm-5">
<div class="fileinput fileinput-new" data-provides="fileinput">
<div class="fileinput-preview thumbnail" data-trigger="fileinput" style="width: 200px; height: 150px;"></div>
<div>
<span class="btn btn-default btn-file"><span class="fileinput-new">select_an_image</span><span class="fileinput-exists">change</span><input type="file" name="userfile"></span>
<a href="#" class="btn btn-default fileinput-exists" data-dismiss="fileinput"><?php echo $this->lang->line("remove"); ?></a>
</div>
</div>
</div>
</div>
And the controller:
if (!empty($_FILES['userfile']['name'])) {
$gamma->CoverFoto = $this->gamma_model->cover_upload(url_title($gamma->Naam, '_', true));
}
Is there a way to use this code so i can upload multiple images?
Have a look upon this code may this help in understanding you how to handle multiple images
#####################
# Uploading multiple#
# Images #
#####################
$files = $_FILES;
$count = count($_FILES['uploadfile']['name']);
for($i=0; $i<$count; $i++)
{
$_FILES['uploadfile']['name']= $files['uploadfile']['name'][$i];
$_FILES['uploadfile']['type']= $files['uploadfile']['type'][$i];
$_FILES['uploadfile']['tmp_name']= $files['uploadfile']['tmp_name'][$i];
$_FILES['uploadfile']['error']= $files['uploadfile']['error'][$i];
$_FILES['uploadfile']['size']= $files['uploadfile']['size'][$i];
$this->upload->initialize($this->set_upload_options());//function defination below
$this->upload->do_upload('uploadfile');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name'];
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
what's happening in code??
well $_FILE---->it is an associative array of items uploaded to the current script via the POST method.for further look this LINK
it's an automatic variable avaliable within all scopes of script
function set_upload_options()
{
// upload an image options
$config = array();
$config['upload_path'] = LARGEPATH; //give the path to upload the image in folder
$config['remove_spaces']=TRUE;
$config['encrypt_name'] = TRUE; // for encrypting the name
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '78000';
$config['overwrite'] = FALSE;
return $config;
}
and in your html markup don't don't forget:
Input element must have multiple="multiple" or just multiple
3.$this->load->library('upload'); //to load library
4.The callback, $this->upload->do_upload() will upload the file selected in the given field name to the destination folder.
5.And the callback $this->upload->data() returns an array of data related to the uploaded file like the file name, path, size etc.
