Add get parameter to URL, using form_open function? - php

Question

I tried to implement standard PHP logic for add, edit articles to blog, so i have add method:
public function add()
{
$this->load->model('admin/Blog_Model');
if (!empty($this->input->post())) {
$user = $this->Blog_Model->addPost($this->input->post());
}
$this->getForm();
}
edit method:
public function edit($id = '')
{
$this->load->model('admin/Blog_Model');
if (!empty($this->input->post())) {
var_dump($id); exit;
$user = $this->Blog_Model->editPost($this->input->post(), $id);
}
$this->getForm($id);
}
and getForm method:
public function getForm($id = '')
{
if (!empty($id)) {
$post = $this->Blog_Model->getPost($id);
$data['action'] = 'admin/blog/edit';
} else {
$data['action'] = 'admin/blog/add';
}
$data['formTitle'] = array(
'name' => 'title',
'id' => 'content-title',
'value' => isset($post['title']) ? $post['title'] : '',
'placeholder' => 'Заглавие',
'class' => 'form-control'
);
$data['formContent'] = array(
'name' => 'content',
'id' => 'content-blog',
'value' => isset($post['content']) ? $post['content'] : '',
'placeholder' => 'Съдържание',
);
$data['formButton'] = array(
'type' => 'submit',
'content'=> 'Изпрати',
'class'=> 'btn btn-primary btn-block btn-flat'
);
$data['head'] = $this->load->view('admin/head', NULL, TRUE);
$data['left_column'] = $this->load->view('admin/left_column', NULL, TRUE);
$this->load->view('admin/header', $data);
$this->load->view('admin/blog_form', $data);
$this->load->view('admin/footer');
}
and blog_form view with form:
<div class="box-body pad">
<?php echo form_open($action); ?>
<div class="box-body">
<div class="form-group">
<label for="content-title">Заглавие:</label>
<?php echo form_input($formTitle); ?>
</div>
<div class="form-group">
<label for="content_blog">Съдържание:</label>
<?php echo form_textarea($formContent); ?>
</div>
<div class="col-xs-12 col-md-3 pull-right">
<?php echo form_button($formButton); ?>
</div>
</div>
<?php echo form_close(); ?>
</div>
So .. everything works perfect, but i have problem with this part:
if (!empty($id)) {
$post = $this->Blog_Model->getPost($id);
$data['action'] = 'admin/blog/edit';
} else {
$data['action'] = 'admin/blog/add';
}
if it's edit i want to send id like GET parameter. I think the problem is there than i does not use standard GET parameters instead of site_url function, when i show all articles here:
<?php foreach ($posts as $post) { ?>
<tr>
<td><?php echo $post['id']; ?></td>
<td><?php echo $post['title']; ?></td>
<td><?php echo $post['content']; ?></td>
<td><div class="btn-group">
Редактирай
Изтрий
</div></td>
</tr>
<?php } ?>

Try to change
if (!empty($id)) {
$post = $this->Blog_Model->getPost($id);
$data['action'] = 'admin/blog/edit';
} else {
$data['action'] = 'admin/blog/add';
}
to
if (!empty($id)) {
$post = $this->Blog_Model->getPost($id);
$data['action'] = 'admin/blog/edit/'.$id; // pass $id to edit controller
} else {
$data['action'] = 'admin/blog/add';
}
