CakePHP Issue with Search and Pagination - search

Question

I have a problem with my CakePhp Site.
My index is showing fine with pagination, but when I search the page, pagination is gone and the search results aren't showing (instead the index is showing without paging).
Any idea where my code is wrong?
class ItemsController extends AppController {
var $name = 'Items';
// load any helpers used in the views
var $helpers = array('Paginator', 'Html', 'Form', 'Javascript', 'Misc', 'Time', 'Tagcloud');
var $components = array('RequestHandler');
/**
* index()
* main index page for items
* url: /items/index
*/
function index() {
// get all options for form
$tags = $this->Item->Tag->find('list', array(
'fields'=>'id, name',
'order'=>'Tag.name',
'conditions'=> array(
'Tag.status'=>'1'
)
));
// add name to option
$tags = array(''=>'Tags') + $tags;
//pr($tags);
// if form submitted
if (!empty($this->data)) {
// if reset button pressed redirect to index page
if(isset($this->data['reset'])) {
$this->redirect(array('action'=>'index'));
}
// init
$url = '';
// remove search key if not set
if($this->data['search'] == '') {
unset($this->data['search']);
}
// loop through filters
foreach($this->data as $key=>$filter) {
// ignore submit button
if($key != 'filter') {
// init
$selected = '';
switch($key) {
case 'tag':
$selected = $tags[$filter];
break;
case 'search':
$selected = $filter;
break;
}
// if filter value is not empty
if(!empty($filter)) {
$selected = $this->slug($selected);
$url .= "/$key/$selected";
}
}
}
// redirect
$this->redirect('/items/index/'.$url);
} else {
// set form options
$this->data['tag'] = '';
$this->data['search'] = '';
}
// if any parameters have been passed
if(!empty($this->params['pass'])) {
// only select active items
$conditions = array('Item.status'=>1);
// get params
$params = $this->params['pass'];
// loop
foreach($params as $key=>$param) {
// get the filter value
if(isset($params[$key+1])) {
$value = $params[$key+1];
}
// switch on param
switch($param)
{
case 'tag':
// get tag
$tag = $this->Item->Tag->find('first', array(
'recursive' => 0,
'conditions' => array(
'Tag.slug'=>$value
)
));
// save value for form
$this->data['tag'] = $tag['Tag']['id'];
break;
case 'search':
// setup like clause
$conditions['Item.name LIKE'] = "%{$value}%";
// save search string for form
$this->data['search'] = str_replace('_', ' ', $value);
break;
}
}
//pr($conditions);
// get all items with param conditions
$items = $this->Item->find('all', array(
'order' => 'Item.name',
'conditions' => $conditions
));
// if tag filter has been set
if(isset($tag)) {
// loop through items
foreach($items as $key=>$item) {
// init
$found = FALSE;
// loop through tags
foreach($item['Tag'] as $k=>$g) {
// if the tag id matches the filter tag no need to continue
if($g['id'] == $tag['Tag']['id']) {
$found = TRUE;
break;
}
}
// if the tag was not found in items
if(!$found) {
// remove from list
unset($items[$key]);
}
}
}
} else {
// get all items from database where status = 1, order by name
$items = $this->Item->find('all', array(
'order' => 'Item.name',
'conditions' => array(
'Item.status'=>1
)
));
}
$this->paginate = array(
'limit' => 10
);
$data = $this->paginate('Item');
// set page title
$this->pageTitle = 'Index Page';
// set layout file
$this->layout = 'index';
// save the items in a variable for the view
$this->set(compact('data', 'tags', 'items'));
}

You'll want to pass your search conditions to the paginate functionality. You do this through the controller's paginate property.
function index() {
...
switch($param) {
...
case 'search':
$this->paginate['conditions']['Item.name LIKE'] = "%{$value}%";
More information on setting up pagination can be found here.
