To upload files using AJAX in CodeIgniter, you can follow these steps:
Step 1: Create a form in your view file with an input field of type file for file upload and a button for submitting the form.
1 2 3 4 |
<form id="uploadForm" method="post" enctype="multipart/form-data">
<input type="file" name="file" id="file">
<button type="button" id="uploadButton">Upload File</button>
</form>
|
Step 2: Write an AJAX script to handle the file upload and update the form data.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
<script type="text/javascript">
$(document).ready(function(){
$('#uploadButton').click(function(){
var form_data = new FormData();
var file_data = $('#file').prop('files')[0];
form_data.append('file', file_data);
$.ajax({
url: '<?php echo base_url("uploadFile"); ?>',
type: 'post',
data: form_data,
contentType: false,
processData: false,
success: function(response){
alert(response);
}
});
});
});
</script>

Step 3: Create a controller method in CodeIgniter to handle the file upload.
1 2 3 4 5 6 7 8 9 10 11 12 |
public function uploadFile(){
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
if($this->upload->do_upload('file')){
echo 'File uploaded successfully';
}else{
echo 'File upload failed';
}
}
|
Step 4: Set up the routes in CodeIgniter to route the AJAX request to the controller method.

$route['uploadFile'] = 'YourController/uploadFile'; |
Now, when you select a file and click the "Upload File" button in the form, the file will be uploaded using AJAX in CodeIgniter.
