CodeIgniter pagination onclick - php

Question

Good day,
Quick question,
I am using CI's pagination to my project,
it works perfectly, but i wanted to add some
filters on it.
i.e. I need to catch its click event.
although I can catch already its click event using this
$("ul.pagination > li a[href]").click(function(e){
loadingStart();
});
my problem is it still redirect to the next page,
what I need is something like this.
if(myVar == 0) {
//do not redirect
} else {
//redirect.
}

Answer 1

Use e.preventDefault(); and then execute your custom function

Answer 2

If you want filter for pagination that use $_GET ... no redirect in js (You can not undo, etc.).
I show you how I do:
Controller:
/**
Example list
**/
public function index()
{
$page = ($this->input->get('page') AND $this->input->get('page')>1)?(intval($this->input->get('page'))-1)*9:1; #9 item for page
#where if isset($_GET)
$where = array();
if($this->input->get('city')) {
$where['users.city'] = $this->input->get('city');
}
if($this->input->get('street')) {
$where['users.street'] = $this->input->get('street');
}
#load model
$this->load->model('users_m');
$view_data['users'] = $this->users_m->GetAll($where,$page,array('users.register_date'=>'DESC'))->result();
//pagination library
$this->load->library('pagination');
$config['base_url'] = site_url('/users');
$config['total_rows'] = $this->users_m->GetAll($where,0)->num_rows();
$config['per_page'] = 9;
$config['full_tag_open'] = "<ul class='pagination'>";
$config['full_tag_close'] ="</ul>";
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = "<li class='disabled'><li class='active'><a href='#'>";
$config['cur_tag_close'] = "<span class='sr-only'></span></a></li>";
$config['next_tag_open'] = "<li>";
$config['next_tagl_close'] = "</li>";
$config['prev_tag_open'] = "<li>";
$config['prev_tagl_close'] = "</li>";
$config['first_tag_open'] = "<li>";
$config['first_tagl_close'] = "</li>";
$config['last_tag_open'] = "<li>";
$config['page_query_string'] = TRUE;
$config['query_string_segment'] = 'page';
$config['reuse_query_string'] = TRUE;
$config['use_page_numbers'] = true;
$config['last_tagl_close'] = "</li>";
$this->pagination->initialize($config);
//variable to template
$view_data['pagination'] = $this->pagination;
$this->load->view('/users/index',$view_data);
}
Model: users_m
/**
* Get all users example
**/
public function GetAll($where=array(),$page=1,$order_by=array(),$limit=9)
{
$this->db->select('users.*');
#order by
if(count($order_by)>0)
{
foreach($order_by as $key=>$value)
{
$this->db->order_by($key,$value);
}
}
$this->db->where($where);
#show all (for pagination calculate)
if($page==0) return $this->db->get_where('users',$where);
#show single page
return $this->db->get_where('users',$where,$limit,(($page==1)?$page-1:$page));
}
And view:
<div id="search_bar">
<?php echo form_open(site_url('/users'),array('class'=>'form-inline','method'=>'get'));?>
<div class="form-group col-lg-2 col-md-4 col-sm-4">
<select name="type" class="form-control">
<option value="" disabled="disabled" selected="selected" >City</option>
<option value="1" <?php if(set_value('city')==1) echo 'selected';?>>London</option>
<option value="2" <?php if(set_value('city')==2) echo 'selected';?>>Warsaw</option>
</select>
</div>
<button type="submit" class="btn btn-primary" style="margin-top:-10px;">Search</button>
<?php echo form_close();?>
</div>
<hr/>
<div id="grid-user" class="row">
<table>
<tbody>
<?php foreach($users as $user):?>
<tr>
<td><?php echo $user->id;?></td>
<td><?php echo $user->firstname;?></td>
<td><?php echo $user->lastname;?></td>
<td><?php echo date("d.m.Y",strtotime($user->register_date));?></td>
</tr>
<?php endforeach;?>
</tbody>
</table>
</div>
<div class="row">
<div class="col-lg-12">
<div style="float:right;"><?php echo $pagination->create_links();?></div>
</div>
</div>
I sorry for my english.
This is example (not checked, written from memory).
Try it :)
