Insert into DB with codeigniter 3 - php

Question

im trying to add new post into my db. I have Model, Controller and View created. Actualy im using rest api for this, but now I want to do it with pure php powerd.
But After form validation is nothing. So when I try to post, nothuing happens.
Here is my code.
Model:
// Create
function create($data) {
// Insert data into DB
$this->db->insert('blog', $data);
return $this->db->insert_id();
}
Controller:
public function add() {
if ($this->ion_auth->is_admin()) {
// Validation rules
$this->form_validation->set_rules('title', 'Titel', 'required');
$this->form_validation->set_rules('teaser', 'Teaser', 'required');
$this->form_validation->set_rules('full', 'Volltext', 'required');
if (($this->form_validation->run() == FALSE)) {
$this->load->view('templates/backend/header', $this->data);
$this->load->view('pages/backend/blog/add', $this->data);
$this->load->view('templates/backend/footer');
} else {
if($this->input->post()) {
$data = array(
'title' => $this->input->post('title'),
'teaser' => $this->input->post('teaser'),
'full' => $this->input->post('full')
);
$this->blog_model->create($data);
redirect(base_url().'blog/');
}
}
} else {
redirect('login');
}
}
And at least my view:
<div class="uk-margin-top">
<?php $attributes = array("class" => "uk-panel uk-panel-box uk-form uk-margin-lage-bottom", "id" => "add-form", "method" => "post");
echo form_open("/backend/blog/add", $attributes); ?>
<div class="uk-form-row">
<label class="uk-form-label" for="title">Title</label>
<input id="title" class="uk-width-1-1 uk-form-large title redactor-box" name="title" placeholder="Beitragstitel" type="text"
value="<?php echo set_value('title'); ?>"/>
<span class="uk-text-danger"><?php echo form_error('title'); ?></span>
</div>
<div class="uk-form-row">
<label class="uk-form-label" for="teaser">Teaser</label>
<textarea id="teaser" class="uk-width-1-1 uk-form-large teaser redactor-box" name="teaser" data-uk-htmleditor></textarea>
<span class="uk-text-danger"><?php echo form_error('teaser'); ?></span>
</div>
<div class="uk-form-row">
<label class="uk-form-label" for="body">Body</label>
<textarea id="full" name="full" rows="4" placeholder="Ihre Nachricht"
value="<?php echo set_value('full'); ?>"></textarea>
<span class="uk-text-danger"><?php echo form_error('full'); ?></span>
</div>
<div class="uk-form-row">
<a class="uk-button uk-button-success" data-action="add-post">Submit</a>
</div>
<?php echo form_close(); ?>
</div>
So my problem is, when I click on my submit button - nothing. Maybe you can show me where my problem is.
Thank you!

For your controller, I think you are missing the form helper and validation library. I have included other comments in the code, but try this:
public function add() {
// you need to load these in:
$this->load->helper('form');
$this->load->library('form_validation');
// I am assuming ion_auth is working, however, I would try this code without
// this conditional statement
if ($this->ion_auth->is_admin()) {
// Validation rules
// Make sure the second parameter is right. I think Titel should be Title.
$this->form_validation->set_rules('title', 'Titel', 'required');
$this->form_validation->set_rules('teaser', 'Teaser', 'required');
$this->form_validation->set_rules('full', 'Volltext', 'required');
// added a triple === instead of == for stricter type checking
if (($this->form_validation->run() === FALSE)) {
// I am assuming $this->data is a property of your controller class
$this->load->view('templates/backend/header', $this->data);
$this->load->view('pages/backend/blog/add', $this->data);
$this->load->view('templates/backend/footer');
} else {
// Check if the form was submitted via $_POST method
if($this->input->post()) {
// I removed your $data array and created it in the model.
// I added a condition here to check if the data was successfully inserted
if ($this->blog_model->create()) {
redirect(base_url().'blog/');
} else {
// output an error message or redirect
}
}
}
} else {
redirect('login');
}
}
For your model, I think you were not passing any data to your model. Try the following for your model:
public function create()
{
// you need to pass an array of data or an object
// the array key corresponds to your db table column
// the array value corresponds to your views input field names
$data = array(
'name' => $this->input->post('title'),
'teaser' => $this->input->post('teaser'),
'full' => $this->input->post('full')
);
// returns true or false
return $this->db->insert('blog', $data);
}
