How to create URL link in search result using Codeigniter? - php

Question

I have already created an search function in Codeigniter and its working properly. The search function shows exactly what I want but I want the result to be link to another page. I am new to Codeigniter. Can somebody please help me?
Here is my Model
public function search($searchterm)
{
$sql = "SELECT title as title, author as author
FROM `edubooks`
WHERE title LIKE '$searchterm' OR author LIKE '$searchterm'";
$q = $this->db->query($sql);
if($q->num_rows() > 0)
{
foreach($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
else
{
return 0;
}
}
/******************Handler for search******************/
public function searchterm_handler($searchterm)
{
if($searchterm)
{
$this->session->set_userdata('searchterm', $searchterm);
return $searchterm;
}
elseif($this->session->userdata('searchterm'))
{
$searchterm = $this->session->userdata('searchterm');
return $searchterm;
}
else
{
$searchterm ="";
return $searchterm;
}
}
Controller
public function search()
{
$searchterm = $this->search_model->searchterm_handler($this->input->get_post('searchterm', TRUE));
$data['results'] = $this->search_model->search($searchterm);
$data['searchterm'] = $searchterm;
$this->load->view('search',$data);
}
and my view
<h2>Library Search System</h2>
<div id="formborder">
<form action ="search" method="post" id="searchform" name="searchform">
<b> Name of book : </b><input type="text" name="searchterm" id="searchterm" value="<?=$searchterm?>" />
<input type="submit" value="search" id="submit" />
</form>
</div>
<div id="tablebody">
<table id="table" width="100%" = border>
<?php if($results == false):?>
<tr>
<td>No records found.</td>
</tr>
<?php else:?>
<tr>
<th>Title</th>
<th>Author</th>
</tr>
<?php foreach($results as $r):?>
<tr>
<td align="center"><?php echo ($r->title); ?></td>
<td align="center"><?php echo ($r->author); ?></td>
</tr>
<?php endforeach;?>
<?php endif;?>
</table>
</div>
<p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>
I just want the result to go another page.

Answer 1

if you want a link per each result to redirect you to another pge, you have to place that new page's URL in the href of your anchor tag, just like any
HTML link. I realize you have a table, what I would do is create another column with a "learn more" link.
So in your case, change this:
<?php foreach($results as $r):?>
<tr>
<td align="center"><?php echo ($r->title); ?></td>
<td align="center"><?php echo ($r->author); ?></td>
</tr>
<?php endforeach;?>
To this:
<?php foreach($results as $r):?>
<tr>
<td align="center"><?= $r->title; ?></td>
<td align="center"><= $r->author; ?></td>
<td align="center">Learn More</td>
</tr>
<?php endforeach;?>
the anchor now looks like this:
<?= base_url()?>controller_name/controller_method/$r->id
which you would want to change to the method name of your choice, perhaps something like this:
<?= base_url()?>books/about/$r->id
^ ^ ^
| | |
| | parameter
| method
controller
it will redirect to that specific controller method passing the id of your book as a parameter. your job now is to build that method so that you can retrieve that specific book by id and parse it to a view.
