To use multiple images in CodeIgniter, you can follow these steps:
- First, you need to set up a controller method to handle the uploaded images. In your controller file, create a method to handle the file upload. You can use the $this->upload->do_upload() method to upload the images.

public function upload_images() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$image_data = array();
$files = $_FILES;
foreach ($files['userfile']['name'] as $key => $image) {
$_FILES['userfile']['name'] = $files['userfile']['name'][$key];
$_FILES['userfile']['type'] = $files['userfile']['type'][$key];
$_FILES['userfile']['tmp_name'] = $files['userfile']['tmp_name'][$key];
$_FILES['userfile']['error'] = $files['userfile']['error'][$key];
$_FILES['userfile']['size'] = $files['userfile']['size'][$key];
if ($this->upload->do_upload('userfile')) {
$data = $this->upload->data();
$image_data[] = $data['file_name'];
} else {
// Handle the upload error
}
}
// Save the image data to the database or do any other operation
// Redirect or show success message
}

- Next, create a form in your view file to allow users to upload multiple images. Make sure to use the multiple attribute in the input tag to allow users to select multiple files at once.

<form method="post" action="<?= base_url('your_controller/upload_images') ?>" enctype="multipart/form-data">
<input type="file" name="userfile[]" multiple>
<button type="submit">Upload Images</button>
</form>
|
- Configure the file upload settings in the config.php file and set the upload path, allowed file types, and maximum file size.
- Make sure to create a folder named 'uploads' in the root directory of your CodeIgniter project where the uploaded images will be stored.
- Finally, handle the uploaded images in your controller method and save the image data to the database or perform any other necessary operations.
By following these steps, you can effectively use multiple images in CodeIgniter.
