If you have a standard ZF2 application and accept application/json requests in addition to application/html, then you have probably noticed that when an error happens, HTML is created, even though the client has requested JSON. One way to fix this is to create a listener on MVC's render event to detect that an error has occurred and substitute a JsonModel in place of the ViewModel. The easiest way to do this in your ApplicationModule. Firstly,… continue reading.

The currencyFormat view helper is very easy to use: echo $this->currencyFormat($value, 'GBP', 'en_GB'); When I was reading the documentation for the currencyFormat view helper, I discovered that you could configure the currency code and locale once rather than in every call: // Within your view script $this->plugin("currencyformat")->setCurrencyCode("GBP")->setLocale("en_GB"); This is obviously useful, but even more useful would be if we could set it once by default and then override if we need to in a specific… continue reading.

If you're using Zend Framework 2's Zend\Db and want to write raw SQL that returns a HydratingResultSet, then you can do this: use Zend\Db\Adapter\AdapterAwareInterface; use Zend\Db\Adapter\Adapter; use Zend\Stdlib\Hydrator\ArraySerializable; use Zend\Db\ResultSet\HydratingResultSet; use Zend\Db\Adapter\DriverResultInterface; use MyEntity\MyEntity; // some sort of entity object class MyMapper implements AdapterAwareInterface { protected $dbAdapter; public function fetchRowsWithValue($fieldValue) { $sql = "SELECT * FROM my_table_name WHERE my_field_name = ? "; $params = array( $fieldValue, ); return $this->fetch($sql, $params); } protected function fetch($sql, $params… continue reading.

If you use ZendDbSql to generate your SQL, then it's useful to find out what the generated SQL looks like. Consider code like this: public function fetchAllWithTitleSince($title, $since) { $sql = new Sql($this->dbAdapter); $select = $sql->select(); $select->from($this->tableName); $select->columns(array('id', 'title', 'url', 'date_updated')); $select->where->like('title', "%$title%"); $select->where->greaterThanOrEqualTo('date_created', date('Y-m-d', strtotime($since))); $statement = $this->dbAdapter->createStatement(); $select->prepareStatement($this->dbAdapter, $statement); return $statement->execute(); } To find out what the generated SQL will look like, you can use the $select's getSqlString() method: $select->getSqlString(); For me, this… continue reading.

This is a short note to myself. Zend\Db\Sql objects allow you to do this: $id = 2; $select->where(array('id' => $id)); which generates the (My)SQL: WHERE `id` = '2' If you want the SQL generated to use the IN operator, then just pass in an array: $idList = array(1, 3, 4); $select->where(array('id' => $idList)); which generates: WHERE `id` IN ('1', '3', '4') This obviously also works for ZendDbSql's update() as well as select().

Zend Framework 2's ModuleManager has the ability to cache the merged configuration information for your application. This is very useful as it allows you to separate out your configuration within the config/autoload directory into logical files without worrying about the performance implications of lots of files. Enabling caching is simply a case of setting these configuration keys in config/application.config.php within the module_listener_options section: 'module_listener_options' => array( 'config_cache_enabled' => true, 'module_map_cache_enabled' => true, 'cache_dir' => 'data/cache/',… continue reading.
