Inserting two fields into a database - php

Question

I am struggling to add data and a category_id in to my database using the MVC architecture.
here is my controller method, which is probably all wrong.
public function create(){
$data['categories'] = $this->get_m->createJoke();
$data = array(
'joke' => $this->input->post('joke'),
'category_id' => $this->input->post('category')
);
$this->get_m->createJoke($data);
$this->load->view('create', $data);
}
Here is my model method:
function createJoke($data){
// Retrieving categories from the database
$categories = $this->db->query('SELECT * FROM category');
$this->db->insert('jokes', $data);
return $categories->result();
}
and finally, this is the form which i want to be able to select a category for a joke:
<?php
echo form_open('home/create');
?>
<p>
<label for="joke">Joke</label>
<input type="text" name="joke" id="joke" />
</p>
<select class="category" name="category">
<option value=0>Select something…</option>
<?php foreach ($categories as $category) { ?>
<option value="<?php echo $category['category_id']; ?>"<?php echo $category_id == $category['category_id'] ? ' selected="selected"' : ''; ?>><?php echo $category['name']; ?></option>
<?php } ?>
</select>
<p>
<input type="button" value="Submit"/>
</p>
<?php echo form_close(); ?>
Before i just had the joke label up (although it did add data in the database), it only added a "0" for some reason.
I have been watching some CRUD tutorials which focus on inserting data, and this is the best i can come up with really!

Answer 1

You didn't check whether form is submitted or not in your controller.
public function create(){
$data['categories'] = $this->get_m->createJoke();
if($this->input->post("joke")!="" and $this->input->post("category")!="") // check post have some value
{
$data = array(
'joke' => $this->input->post('joke'),
'category_id' => $this->input->post('category')
);
$this->get_m->createJoke($data);
}
$this->load->view('create', $data);
}

$data = array(
'joke' => $this->input->post('joke'),
'category_id' => $this->input->post('category')
);
$this->get_m->createJoke($data);
$this->load->view('create', $data);
}
public function selectdata(){
$data['categories'] = $this->get_m->get_joke_categoryid();
}
//model
function createJoke($data){
$this->db->insert('joker', $data);
$this->session->set_flashdata("message", "Contract record successfully created.");
function get_joke_categoryid(){
$query = $this->db->get('joker');
return $query->result();
}
