Codeigniter Updating Edit Page - php

Question

I have created an edit page which repopulates their information into the correct fields (based on the ID) and they can amend the details...
What I want now is for the Submit button to update this information in the database table?
This is the Edit Section in my Controller:
function edit($id = 0){
$this->load->model('blogmodel');
if( $this->input->post() ){ #if form submitted
$data = array();
$id = $this->input->post('id'); #to be used in the where clause for updation
$data['name'] = $this->input->post('name');
$data['address'] = $this->input->post('address');
$data['sEmail'] = $this->input->post('sEmail');
$this->blogmodel->update_blog($data,$id);
}else{
// Form Validation required
$this->load->library('form_validation');
$this->form_validation->set_rules('name', 'Name', 'required');
$this->form_validation->set_rules('address', 'Address', 'required');
$this->form_validation->set_rules('sEmail', 'Sender Email', 'required|valid_email');
$this->form_validation->set_message('required', '%s is required');
$this->form_validation->set_error_delimiters('<span class="error">', '</span><br />');
$sql = 'SELECT * FROM databse.blogs WHERE id = ?';
echo $sql . ' - '. $id;
$sql_params = array($id);
$query = $this->db->query($sql, $sql_params);
$form = $query->row_array();
//$date['form'] = $form;
$data['inputs'] = array('name' => $form['name'],
'address' => $form['address'],
'semail' => $form['email'],
'nickname' => $form
);
$data['Name']= $form['name'];
$data['Address']= $form['address'];
$data['Email']= $form['email'];
$this->load->view('blog_content',$data);
$data = $this->input->post();
$result = $this->blogmodel->update_blog($data,$id);
$this->load->view('blog_success');
}
}
}
So Far this is my Model:
function send_blog(&$data){
$data['name'] = $this->input->post('name');
$data['address'] = $this->input->post('address');
$data['sEmail'] = $this->input->post('sEmail');
$sql = "UPDATE database.blogs (name, address, email) WHERE id = $id
VALUES (".$this->db->escape($data['name']).",
".$this->db->escape($data['address']).",
'".$data['sEmail']."');";
$this->db->query($sql);
}
function update(&$data,$id){
$data['name'] = $this->input->post('name');
$data['address'] = $this->input->post('address');
$data['sEmail'] = $this->input->post('sEmail');
$this->db->where('id', $this->input->post('id'));
$this->db->update('blog', $data);
}
}

What is the current_url() here? I'm guessing it to be function edit(). In your function edit just do the below changes:
function edit($id = 0){
if( $this->input->post() ){ #if form submitted
$data = array();
$id = $this->input->post('id'); #to be used in the where clause for updation
/*
Retrieve all the post variables in the $data and send to model for updation
*/
$this->your_model->update_function( $data, $id );
redirect('controller/edit/'.$id, 'refresh'); #redirect to the same function to show the form or success page
}else{
/*
Your rest of the function as it is
*/
}
}
Update
Your controller changes:
function edit($id = 0){
if( $this->input->post() ){ #if form submitted
$data = array();
$id = $this->input->post('id'); #to be used in the where clause for updation
$data['name'] = $this->input->post('name');
$data['address'] = $this->input->post('address');
$data['sEmail'] = $this->input->post('sEmail');
$data['nickname'] = $this->input->post('nickname');
$data['blogregion'] = $this->input->post('blogregion');
$data['startdate'] = $this->input->post('startdate');
$data['blogtitle'] = $this->input->post('blogtitle');
$data['timesperweek'] = $this->input->post('timesperweek');
$data['profiletext'] = $this->input->post('profiletext');
$data['abouttext'] = $this->input->post('abouttext');
$data['status'] = 0;
$data['userid'] = $id;
$this->newblogsetupmodel->update_blogforus( $data, $id );
redirect('newblogsetup/edit/'.$id, 'refresh'); #redirect to the same function to show the form or success page
}else{
#rest of the controller here
}
}
Your model changes:
function update_blogforus($data, $id){
echo "<pre>";print_r( $data );die; #to print the data received from controller, see if its coming okay or make correction in the controller for the same
/*$data['name'] = $data['name'];
$data['address'] = $data['address'];
$data['sEmail'] = $data['sEmail'];
$data['nickname'] = $data['nickname'];
$data['blogregion'] = $data['blogregion'];
$data['startdate'] = $data['startdate'];
$data['blogtitle'] = $data['blogtitle'];
$data['timesperweek'] = $data['timesperweek'];
$data['profiletext'] = $data['profiletext'];
$data['abouttext'] = $data['abouttext'];
$data['status'] = 0;
//$data['userid'] = $data['user']->id;
*/
$this->db->where('id', $id);
$this->db->update('newblogsetup', $data);
echo $this->db->last_qeury();die; #to see the query being executed, run it in your phpMyadmin and see if its updating as required.
}
New Changes
Controller:
$data['id'] = $id; #save the data in an element to echo in the hidden field of the form
$this->load->view('newblogsetup_sent', $data); #load the data to the page
In your edit page change this line
<?php echo form_hidden('id');?>
To:
<?php echo form_hidden( 'id', $id );?>
