PHP Search not passing query on URL - php

Question

I have a search function on my PHP (CodeIgniter) website. But I want to pass the query terms in the URL so Google Analytics can track that info. I think this is kind of basic but I'm just learning how to code.
This is my HTML:
<form class="navbar-form navbar-right mtop10 mright10 hidden-xs" role="search" method="post" action="<?php echo base_url('cursos/searchCourse'); ?>">
<div class="form-group">
<input class="form-control" type="text" name="search_course" placeholder="Busque um curso" />
<input type="hidden" name="url" value="<?php echo current_url(); ?>" />
</div>
<button class="btn btn-md btn-default" type="submit" value="">
<span class="glyphicon glyphicon-search"></span>
</button>
<?php if($this->session->flashdata('search_error')) : ?>
<?php $errors = $this->session->flashdata('search_error');echo $errors['search_course']; ?>
<?php endif; ?>
</form>
This is the function searchCourse:
public function searchCourse(){
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<p class="alert alert-danger mtop5" role="alert">', '</p>');
$this->form_validation->set_rules('search_course', 'Busca', 'trim|required|min_length[2]|xss_clean');
$this->form_validation->set_message('required', 'Campo de preenchimento obrigatório');
$this->form_validation->set_message('min_length', 'O campo precisa conter pelo menos 2 caracteres');
if ($this->form_validation->run()){
$search = $this->curso_model->getCoursesBySearch($this->input->post('search_course'));
if(!empty($search)){
$this->index($search);
}else{
$this->set_flashdata('search_empty', 'search_empty', $this->input->get('url'));
}
}else{
$errors = array('search_course'=>form_error('search_course'));
$this->set_flashdata('search_error', $errors, $this->input->get('url'));
}
}
And this is my model:
public function getCoursesBySearch($search){
$this->db->select('*');
$this->db->from('curso');
$this->db->group_by('curso_nome');
$this->db->like('curso_nome', $search);
//$this->db->or_like('curso.curso_descricao', $search);
//$this->db->or_like('curso.curso_categoria', $search);
$this->db->or_like('tags.tags_nome', $search);
$this->db->join('curso_tags', 'curso_tags.curso_id = curso.curso_id');
$this->db->join('tags', 'tags.tags_id = curso_tags.tags_id');
//$this->db->where('curso_status', 1);
//$this->db->distinct();
$this->db->distinct();
$query = $this->db->get();
print_r($search);
//exit;
return $query->result();
}
Can anybody give me a clue?
Cheers!

Use jquery to modify the action attribute dynamically. Assign id attritube to each of the form elements including form itself
HTML :
<form id="my_form" method="post" action="dummy.html">
<input id="search_text" type="text" name="search_course" placeholder="Busque um curso" />
<input type="hidden" name="url" value="sdff" />
<button id="my_button" type="submit" value="Submit"> </button>
</form>
Jquery: (Add below your form)
<script>
$('#my_button').click(function(){
var search_text = $("#search_text").val();
// Replace my_search.php with actual landing page
$('#my_form').attr('action', 'my_search.php' + '?search=' + search_text);
});
</script>
Note : Your search text will be decoded in URL (in case of spaces, etc) and you have decode the URL at the landing page.

Change the method from post to get, so the values will be in the URL :
<form class="navbar-form navbar-right mtop10 mright10 hidden-xs" role="search" method="post" action="<?php echo base_url('cursos/searchCourse'); ?>">
replace with :
<form class="navbar-form navbar-right mtop10 mright10 hidden-xs" role="search" method="get" action="<?php echo base_url('cursos/searchCourse'); ?>">
