ZF-5189: Zend_Paginator_Adapter_DbSelect - no way to bind data to placeholders

Issue Type: Improvement Created: 2008-12-08T20:11:09.000+0000 Last Updated: 2010-06-07T12:34:41.000+0000 Status: Resolved Fix version(s): Reporter: Phil Brown (philbrown) Assignee: Jurrien Stutterheim (norm2782) Tags: - Zend_Paginator

Given a query with named parameter placeholders, eg

<pre class="highlight">

there's currently no way to pass the array of bind variables to the pagination adapter for use in the getItems() or count() / setRowCount() methods.

Given that this is the recommended method of parameter passing (at least for non-string values), shouldn't it be supported by the adapter?

A Zend_Db_Statement object isn't flexible enough to be used in a similar way as a Zend_Db(_Table)_Select object. The current Zend_Db_Select adapter works by modifying the original query and converting it into a COUNT query to determine the amount of items in the result set. Zend_Db_Statement uses plain strings for the unbound query. At the moment I don't see a way to create decent support for Zend_Db_Statement. Suggestions are welcome, but I'll postpone this issue until a nice way to support this is offered. Please use Zend_Db(_Table)_Select for paginating Db results in the mean while.

I've solved this by extending Zend_Paginator_Adapter_DbSelect with the following alterations.

<pre class="highlight">
protected $_bind = array();

public function __construct(Zend_Db_Select $select, array $bind = array())

public function setBindValues(array $bind)
    $this->_bind = $bind;
    return $this;

in setRowCount()

<pre class="highlight">
$stmt = $rowCount->getAdapter()->query($rowCount, $this->_bind);
$result = $stmt->fetch();

and similarly in getItems()

<pre class="highlight">
$stmt = $this->_select->getAdapter()->query($this->_select, $this->_bind);
return $stmt->fetchAll();

Of course, when using the Zend_Paginator::factory() method, the bind data needs to be added after the paginator is created. Otherwise, the array can be set using the adapter's constructor.

Has been resolved with ZF-2017 and ZF-3220

Phil Brown's suggestion in the comment above is a good one.

It should be accepted into ZF in my opinion.

Here's a patch that works for me.
