<input type="file" class="default" id="imageupload1" name="imageupload[]">
</form>
Whenever I am uploading file it displaying warning is_uploaded_file() expects parameter 1 to be string, array given. How can I resolve it?

Answer 1

try this
//place this code in your function for multiple image upload
$data = array();
if(!empty($_FILES['imageupload']['name']))
{
$filesCount = count($_FILES['imageupload']['name']);
for($i = 0; $i < $filesCount; $i++){
$_FILES['imageupload']['name'] = $_FILES['imageupload']['name'][$i];
$_FILES['imageupload']['type'] = $_FILES['imageupload']['type'][$i];
$_FILES['imageupload']['tmp_name'] = $_FILES['imageupload']['tmp_name'][$i];
$_FILES['imageupload']['error'] = $_FILES['imageupload']['error'][$i];
$_FILES['imageupload']['size'] = $_FILES['imageupload']['size'][$i];
$uploadPath = 'uploads/';
$config['upload_path'] = $uploadPath;
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if($this->upload->do_upload('imageupload')){
$fileData = $this->upload->data();
$uploadData[$i]['file_name'] = $fileData['file_name'];
$uploadData[$i]['created'] = date("Y-m-d H:i:s");
$uploadData[$i]['modified'] = date("Y-m-d H:i:s");
}
}
if(!empty($uploadData)){
//Insert file into the database using your model
}
}

Probably your input name should be without brackets:
<input type="file" class="default" id="imageupload1" name="imageupload">
