codeigniter form with image upload - php

Question

I have a field of my form (which is uploading personal picture). So the user selects image from pc and submit the form.
Controller:
function do_upload()
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100000';
$config['max_width'] = '10240';
$config['max_height'] = '7680';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
print_r($this->upload->data());
$datafoto = $this->upload->data();
$nm_file = time().$datafoto['orig_name'];
$this->load->model('mkegiatan');
$this->mkegiatan->update_foto($nm_file);
copy('images/'.$datafoto['orig_name'], 'images/'.$nm_file);
}
}
And contoller edit event like this:
function edit_kegiatan()
{
$id_kegiatan = $this->uri->segment(4);
//set validation properties
$this->form_validation->set_rules('tanggal_kegiatan', 'Tanggal', 'required');
$this->form_validation->set_rules('nama_kegiatan', 'Judul Berita', 'required');
$this->form_validation->set_rules('content', 'Content', 'required');
//run validation
// jika dia ingin update data atau form validation error
if ($this->form_validation->run() == FALSE) {
$data = $this->mkegiatan->get_by_id($id_kegiatan);
$this->load->model('mkegiatan');
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100000';
$config['max_width'] = '10240';
$config['max_height'] = '7680';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) //you forgot this
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
//print_r($this->upload->data());
$datafoto=$this->upload->data();
$nm_file = time().$datafoto['orig_name'];
$data = array(
'tanggal_kegiatan' => $this->input->post('tanggal_kegiatan'),
'nama_kegiatan' => $this->input->post('nama_kegiatan'),
'content' => $this->input->post('content'),
'image' => $nm_file
);
$this->mkegiatan->update_kegiatan($id_kegiatan,$data);
$this->session->set_flashdata('message', generateSuccessMessage('Data berhasil diupdate'));
redirect(site_url('admin/kegiatan'));
}
}
$this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
//var_dump($data);
//$tmp_data = array('id_kegiatan' => $id_kegiatan);
$this->data['contents'] = $this->load->view('admin/kegiatan/edit_kegiatan', $this->data, true);
$this->load->view('template/wrapper/admin/wrapper_ukm',$this->data);
}
View:
<?php echo form_open(current_url(),'name=form'); ?>
<div class="fours fields">
<div class="field">
<div class="ui vertical segment">
<div class="date field">
<label>Tanggal</label>
<div class="ui small icon input left">
<input type="text" id="datepicker" placeholder="xxxx-xx-xx" name="tanggal_kegiatan" value="<?php echo $tanggal_kegiatan;?>"><?php echo form_error('tanggal_kegiatan', '<div class="ui red pointing label">', '</div>'); ?>
<i class="calendar icon"></i>
</div>
</div>
</div>
</div>
</div>
<div class="two fields">
<div class="field">
<label>Nama Acara</label>
<div class="ui small left icon input">
<input type="text" placeholder="Nama Kegiatan" name="nama_kegiatan" value="<?php echo $nama_kegiatan;?>"><?php echo form_error('nama_kegiatan', '<div class="ui red pointing label">', '</div>'); ?>
<i class="text file outline icon"></i>
</div>
</div>
</div>
<div class="field">
<label>Isi Kegiatan</label>
<textarea placeholder="Text" name="content">
<?php echo $content;?>
</textarea><?php echo form_error('content', '<div class="ui red pointing label">', '</div>'); ?>
</div>
<input type="file" name="userfile" size="20">
<input class="ui small blue submit button" type="submit" value="Save">
</form>
Do I need to create two separate forms to accomplish this (one for the image upload and one for the text input)? Or is it possible to write a function in the controller that can validate and process both the upload and text input simultaneously?

Answer 1

try this
function tambah_kegiatan()
{
//set validation properties
$this->form_validation->set_rules('nama_kegiatan', 'Judul Berita', 'required');
if ($this->form_validation->run() == true)
{
$this->load->model('mkegiatan');
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100000';
$config['max_width'] = '10240';
$config['max_height'] = '7680';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) //you forgot this
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
print_r($this->upload->data());
$datafoto=$this->upload->data();
$nm_file = time().$datafoto['orig_name'];
$data = array(
'nama_kegiatan' => $this->input->post('nama_kegiatan'),
'image' => $nm_file
);
$this->mkegiatan->insert_kegiatan($data);
$this->session->set_flashdata('message', generateSuccessMessage('Data berhasil ditambah'));
redirect(site_url('admin/kegiatan'));
}
}
$this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
$this->data['contents'] = $this->load->view('admin/kegiatan/tambah_kegiatan', '', true);
$this->load->view('template/wrapper/admin/wrapper_ukm',$this->data);
}
and your image folder having all permissions
function edit_kegiatan($id_kegiatan='')
{
//set validation properties
$this->form_validation->set_rules('tanggal_kegiatan', 'Tanggal', 'required');
$this->form_validation->set_rules('nama_kegiatan', 'Judul Berita', 'required');
$this->form_validation->set_rules('content', 'Content', 'required');
//run validation
// jika dia ingin update data atau form validation error
if ($this->form_validation->run() == FALSE) {
$data = $this->mkegiatan->get_by_id($id_kegiatan);
$this->load->model('mkegiatan');
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100000';
$config['max_width'] = '10240';
$config['max_height'] = '7680';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile')) //you forgot this
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
//print_r($this->upload->data());
$datafoto=$this->upload->data();
$nm_file = time().$datafoto['orig_name'];
$data = array(
'tanggal_kegiatan' => $this->input->post('tanggal_kegiatan'),
'nama_kegiatan' => $this->input->post('nama_kegiatan'),
'content' => $this->input->post('content'),
'image' => $nm_file
);
$this->mkegiatan->update_kegiatan($id_kegiatan,$data);
$this->session->set_flashdata('message', generateSuccessMessage('Data berhasil diupdate'));
redirect(site_url('admin/kegiatan'));
}
}
$this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
//var_dump($data);
//$tmp_data = array('id_kegiatan' => $id_kegiatan);
$this->data['contents'] = $this->load->view('admin/kegiatan/edit_kegiatan', $this->data, true);
$this->load->view('template/wrapper/admin/wrapper_ukm',$this->data);
}
