CodeIgniter: Is possible to have current page link by pagination library? - php

Question

I have created pagination item by CodeIgniter pagination library with following code:
echo $this->pagination->create_links()
Everything is working well.
Now i want to load data by ajax and i have done already ajax part. But problem is to make clicked item as a current item and to arrange link for current item as it is no longer current.
Suppose i have a pagination as following:
[1] 2 [3] [4] [5] [6] [>] [Last >]
Now 2 is current item and 4 is clicked item.
I have checked CodeIgniter Pagination library, but it doesn't have any option to enable or disable current page link. Is it possible to have current page link without modifying the library?
Thanks in advance.

Answer 1

I take it all back. The Pagination library will need to be changed.
https://github.com/EllisLab/CodeIgniter/blob/develop/system/libraries/Pagination.php
Line 560
$output .= $this->cur_tag_open.$loop.$this->cur_tag_close
Will need to be replaced with
$append = $this->prefix.$i.$this->suffix;
$output .= $this->num_tag_open.'<a href="'.$this->base_url.$append.'"'.$attributes.$this->_attr_rel('start').'>'.$loop.'</a>'.$this->num_tag_close;
That should do it.

You don't need to modify anything on server side. just use plain old vanila jquery.
Here's how to do it.
Let's say i wrapped the links in a <div id="pagination"></div>
Now, to call ajax, use jQuery(body).on('click','#pagination a', function(e){....}).
Here in this code, jQuery(this) will refer to the link that was clicked.
Next, after successful call, remove the active (or any other class that is given ) from all the links. like jQuery('#pagination a').removeClass('active').
Next, if you still remember, jQuery(this) still refered to the current clicked item. (better save it as var current = jQuery(this) at the start of the clicked even so that the reference does not change. Now, just add the class. jQuery(current).addClass('active')
You are done! No need to do anything fancy anything in server side. Sometimes client side is enough.
P.S. i forgot how CI renders the pagination links. if you give the links, i can write the actual code.

var_dump($this->pagination); everything is inside
then if you check Pagination.php library you have these params available too:
var $cur_tag_open = '';
var $cur_tag_close = '';
so try calling them when initializing pagination
$pagination['cur_tag_open'] = '<span class="current-link">';
$pagination['cur_tag_close'] = '</span>';
$this->pagination->initialize($pagination); //now current link should be wrapped into the <span class="current-link"></span>

Answer 4

I don't believe you need to change anything in the Pagination library. You just need to use the uri_segment() function.
The Pagination library takes an argument as follows:
$config['uri_segment'] = 5;
The default value is 3. [Use a value that will work with your URI structure].
This variable is used along with the uri_segment() function to determine the current page, in the latest version of CodeIgniter 2.1.4 you will find it starting on line 142 in the Pagination.php library.
The appropriate uri_segment for the page identifier could be calculated as follows, if using a URI like this one: http://example.com/controller/function/page/20 then you can get the current page as follows,
$page = $this->uri_segment(4);
Hope that helps.

You really dont need to change anything.
Once you have your automatic page set
$page = 2 // Page should be set automatically
Now try this
$config["cur_page"] = $page;
