Zend Framework Components by leek

Collection of various helpers and extensions to the Zend Framework project.

Leek_Multidb

Maybe I'm just using it wrong (quite possible) but what's the point of the Zend_Application_Resource_Multidb if I can't realistically use multiple adapters? Leek_Multidb aims to automate the process of writing to a master and reading from slaves using what is already built into the Zend Framework so that the integration is as seamless as possible.

Step #1

Setup the Multidb Resource as you always would, except add the <read> or <write> parameters as shown below:

...
<resources>
    ...
    <multidb>
        <master>
            <adapter>mysqli</adapter>
            <host>master-host</host>
            <port>3306</port>
            <username>root</username>
            <password></password>
            <dbname>database</dbname>
            <profiler>true</profiler>
            <charset>utf8</charset>
            <read>false</read>
        </master>
        <slave1>
            <adapter>mysqli</adapter>
            <host>slave1-host</host>
            <port>3306</port>
            <username>root</username>
            <password></password>
            <dbname>database</dbname>
            <profiler>true</profiler>
            <charset>utf8</charset>
            <write>false</write>
        </slave1>
    </multidb>
    ...
</resources>
...

Step #2

The last step is just as simple - anywhere that you extend Zend_Db_Table_Abstract, just extend Leek_Multidb_Table_Abstract instead. Also, for Zend_Db_Table_Row_Abstract, extend Leek_Multidb_Table_Row_Abstract instead. Leek_Multidb will automatically swap between writers and readers depending on what type of operation you're doing.

Leek_Config / Leek_Application_Resource_Config

Load as many config files as you'd like (of any type) in your Application config file. Example (application.xml):

...
<resources>
    ...
    <config>
        <navigation>
            <path>../application/configs/navigation.xml</path>
            <useEnvironment>true</useEnvironment>
            <cacheKey>navigation</cacheKey>
            <cacheManagerKey>config</cacheManagerKey>
        </navigation>
    </config>
    ...
</resources>
...

Options

• path: Path to config file
• useEnvironment: Used if you want the config to have inheritence based on ENV
• cacheKey: Key used to load from our Zend_Cache object (default: 'config')
• cacheManagerKey: Key used to load from our CacheManager Resource (default: 'config')

Once you have this setup, you can do this anywhere to get your Zend_Config array:

$config = Leek_Config::getBootstrapConfig('navigation')

Leek_Captcha_ImageGrid

A Zend Framework implementation of Image Recognition CAPTCHA (similar to ASIRRA, PIX, etc.). See this image for a reference of what this CAPTCHA adapter could look like.

Example Controller Usage

$captcha = new Leek_Captcha_ImageGrid(array('salt' => 'CHANGE_ME'));

if ($this->_request->isPost()) {
    $formData = $this->_request->getPost();          
    if ($captcha->isValid($formData)) {
        // ...
    }
} else {
    $captcha->generate();
}

$this->view->captcha = $captcha;

Example ViewScript Usage

$this->captcha->render($this);

Leek_Error

This is a fork of FFFUU-Exception error handler by kurtschwarz. I loved the design but wanted something that could easily drop in to any of my Zend Framework projects (and wasn't NSFW) - so here it is. See this image for a reference of what this error handler looks like.
