    $all = $this->input->get('all');

    if($all)
    {
        $keywords = $this->input->get('search');
        $data['search'] = $keywords;
        $this->session->set_flashdata('search', $keywords);
        $query = "SELECT *  FROM `investOffers`, `news`";
        $counts = "SELECT count(*) as count FROM  `investOffers`, `news`";
        $first = false;
        if($keywords)
        {
            $data['keywords'] = $keywords;
            $this->session->set_flashdata('keywords', $keywords);
            $keywords = explode(" ", $keywords);
            foreach($keywords as $k)
            {
                if(!$first)
                {
                    $query .= " WHERE investOffers.desc LIKE '% ".$k." %' OR investOffers.title LIKE '% ".$k." %'";
                    $query .= " OR news.desc LIKE '% ".$k." %' OR news.title LIKE '% ".$k." %'";
                    $counts .= " WHERE investOffers.desc LIKE '% ".$k." %' OR investOffers.title LIKE '% ".$k." %'";
                    $counts .= " OR news.desc LIKE '% ".$k." %' OR news.title LIKE '% ".$k." %'";
                    $first = true;

                }
                else
                {
                    $query .= " OR investOffers.desc LIKE '% ".$k." %' OR investOffers.title LIKE '% ".$k." %'";
                    $query .= " OR news.desc LIKE '% ".$k." %' OR news.title LIKE '% ".$k." %'";
                    $counts .= " OR investOffers.desc LIKE '% ".$k." %' OR investOffers.title LIKE '% ".$k." %'";

            }


        }
            $page = $this->uri->segment(2);
            if($page)
            {
                $query .= " ORDER BY investOffers.date DESC LIMIT ".$page.", 10";
                $counts .= " ORDER BY investOffers.date DESC LIMIT 10";
            }
            else
            {
                $query .= " ORDER BY investOffers.date DESC LIMIT 10";
                $counts .= " ORDER BY investOffers.date DESC LIMIT 10";
            }
        $data['query'] = $this->db->query($query);
        $counts = $this->db->query($counts);
        foreach($counts->result() as $q)
        {

        $count = $q->count;
        break;

        }
        $config['base_url'] = base_url().'/search';
        $config['prev_link'] = false;
        $config['next_link'] = false;
        $config['last_link'] = false;
        $config['first_link'] = false;
        $config['suffix'] = '?'.http_build_query($_GET, '', "&");
        $config['cur_tag_open'] = '<strong><img src="'.IMAGE.'pagerArrow.png" class="pagerArrow" />';
        $config['cur_tag_close'] = '</strong>';
        $from = intval($this->uri->segment(2));
        $config['per_page'] =  10;   
        $config['num_links'] = 5;    
        $config['uri_segment'] = 2;  
        $config['total_rows'] = $count; 
        $this->pagination->initialize($config);
        $data['pager'] = $this->pagination->create_links();
        $data['content'] = $this->load->view(SITE.'search', $data, true);
        $this->load->view(SITE.'layout', $data);
        return true;

    }

so this is a search query, first we check if a search is “all”, it means search by all the site, so then i make a array of keywords separated by whitespaces, entered in the form, so then i put it in a flash session for preg_match in the view, this is for preg_match highlighting text in the view of generated results, so then i make a concatenation of the query be adding more LIKE , so the problem is when i input 1 keyword, it gives me different results and its okey, but when i enter 2 or many keywords, it gives me the same results, i mean a list of result that are exact the same, i can’t understand why is that, in the view its all okay, the problem is in this place of code, i have tried to set th DISTINCT keyword in the query, but it does not helped…

ps: this is codeigniter, MVC, this is a controller, i don’t use models, because i don’t want to open many files 🙂

Answer 1

Check if your

$keywords = explode(" ", $keywords);

is returning a length greater then 1. Since you are getting $keywords from a GET, it is possible that you need to urldecode your variable before passing it in the explode function.

$keywords = urldecode($keywords);
