CakePHP How to Persist Search Querystring to Subsequent Paginator Pages - php

Question

I had a search page that filtered correctly, but when it paginated you would lose the data since I was POSTing it. So I switched it to a GET, but I can't figure out how to add the http_build_query( $params ) that I passed back to the paginator.
I've tried setting query params in the paginator url in options, but with no luck and the API doesn't mention adding the query params.
How do I set the search results query params so the different pages know what they were being filtered on? So a search on name=steve and company=SomeCompany is maintained through page 2, 3, 4, with 10 results each, and doesn't reset to show all non-filtered 100 results.
Simple Example Pagination in Controller
$this->paginate = [
'limit' => 5,
'order' => [ 'CollectionAgencyAgent.id' => 'desc' ]
];
return $this->paginate( $this->CollectionAgencyAgent, $conditions );
VIEW with Pagination
<ul class="pagination <?php echo $class ?>">
<?php
$this->Paginator->options( [
'url' => [
'controller' => ''
]
] );
?>
<?php echo $this->Paginator->prev( __( '« Previous' ), [
'escape' => false,
'tag' => 'li',
'class' => 'arrow',
'disabledTag' => 'a'
] ); ?>
<?php echo $this->Paginator->numbers( [
'separator' => '',
'tag' => 'li',
'currentTag' => 'a'
] ); ?>
<?php echo $this->Paginator->next( __( 'Next »' ), [
'escape' => false,
'tag' => 'li',
'class' => 'arrow',
'disabledTag' => 'a'
] ); ?>
</ul>

Answer 1

The paginator class automatically merges the current request parameters:
public function beforeRender($viewFile) {
$this->options['url'] = array_merge($this->request->params['pass'], $this->request->params['named']);
if (!empty($this->request->query)) {
$this->options['url']['?'] = $this->request->query;
}
parent::beforeRender($viewFile);
}
So the short answer is to do nothing, and that'll just work.
The reason it doesn't work with the code in the question is that this call:
$this->Paginator->options( [
'url' => [
'controller' => ''
]
] );
Which will wipe out the Paginator's run time url options. So, to prevent the problem in the question - just delete that call (and then, probably fix the routing problem which prompted you to add it =)).
