Form posting with '_GET' parameters
A while ago, I was working on a searchengine for my site. When a search is performed, the url should show all the parameters so it is possible for user to add the search to their favorites. This code snippet shows how I accomplished this.
More details of this problem are described here:
[url]http://groups.google.com/group/cake-php/browse_thread/thread/d1c13c9338b8fe26[/url]
The trick is to submit a form using 'POST', and than redirect to an URL with named parameters (cake's alternative to regular _GET variables) as suggested by Stephen Orr. I havn't fully tested it so if you find any bugs, your free to make a comment about it.
Here's my code:
Here's my code:
Controller Class:
<?php
class MySearchController extends AppController{
function search(){
if (empty($this->data)){
if (!empty($this->params["named"])){
//unserialize passed params
$this->data = $this->unSerializeData($this->params["named"]);
//do search logic
$this->doSearchLogic();
} else {
//do nothing, show search form
}
} else {
//serialize and redirect
$searchParams = $this->serializeData($this->data);
$this->redirect(array("action"=>"index", $searchParams));
}
}
/**
* Converts named params to array
*
* @param array $namedParams
* @return array
*/
function unSerializeData($namedParams){
$result = array();
if (is_array($namedParams)){
foreach($namedParams as $fieldName=>$value){
$field = explode(".", $fieldName);
if (count($field) == 2){
$result[$field[0]][$field[1]] = $value;
} elseif(count($field) == 1) {
$result[$field[0]] = $value;
}
}
}
return $result;
}
/**
* Converts the this->data array to named parameters
*
* @param array $data
* @return string
*/
function serializeData($data){
$result = array();
if (is_array($data)){
foreach ($data as $model=>$values) {
if (is_array($values)){
foreach($values as $name=>$val){
$result[] = sprintf("%s.%s:%s", $model, $name, $val);
}
} else {
$result[] = sprintf("%s:%s", $model, $values);
}
}
}
$result = implode("/", $result);
return $result;
}
}
?>
also integrated with ajax pagination, also tried another query string solutions but this is the one that fits bether
Component Class:
<?php
<?php
class SerializeComponent extends Object
{
/**
* Converts named params to array
*
* @param array $namedParams
* @return array
*/
function unSerializeData($namedParams){
$result = array();
if (is_array($namedParams)){
foreach($namedParams as $fieldName=>$value){
$field = explode(".", $fieldName);
if (count($field) == 2){
$result[$field[0]][$field[1]] = $value;
} elseif(count($field) == 1) {
$result[$field[0]] = $value;
}
}
}
return $result;
}

function serializeData($data){
$result = array();

if (is_array($values)){
foreach($values as $name=>$val){
$result[] = sprintf("%s.%s:%s", $model, $name, $val);
}
} else {
$result[] = sprintf("%s:%s", $model, $values);
}
}
}
$result = implode("/", $result);
return $result;
}
}
?>
?>
Controller Class:
<?php
<?php
class UsersController extends AppController {
var $name = 'Users';
var $helpers = array('Html', 'Form','Ajax');
var $components = array('RequestHandler','Serialize');
var $paginate = array(
'limit' => 1,
'order' => array(
'User.nome' => 'asc',
'User.sobrenome' => 'asc',
)
);
var $namedArgs = TRUE;
function search(){
$where = array();
if (empty($this->data)){
if (!empty($this->params["named"])){
//unserialize passed params
$this->data = $this->Serialize->unSerializeData($this->params["named"]);
} else {
//do nothing, show search form
}
}
$where = $this->User->generateWhere($this->data);
$this->User->recursive = 0;
$searchParams = $this->Serialize->serializeData($this->data);
$this->set('searchParams', $searchParams);
$this->set('users', $this->paginate('User',$where));
}
?>
View Template:
...
$paginator->options(array('url' => $searchParams));
...
