Setting Up Zend Framework 2 Autoloader

May 13th, 2014

If you’re like me, you like to dig into the belly of things and twist them to your own uses. Tonight, I’ve been monkeying around with ZF2 autoloaders, and working out how they function.

I store my ZF install in a dir (Zend/) in my include path, so I don’t have to maintain copies for each site on my server.

Some useful notes on this:

The stock ZF2 download does not include a pre-generated classmap file. To generate this, go into the default unpacked archive folder, into bin/ and run this command:

php classmap_generator.php -l "/usr/share/php/Zend/"

[code language=”php”]
// How to get an absolute path to the generated classmap file (return: /usr/share/php/Zend/autoload_classmap.php)
$classmapPath = stream_resolve_include_path(‘Zend/autoload_classmap.php’);

// How to get the autoload up and running
require_once ‘Zend/Loader/ClassMapAutoloader.php’;
$autoloader = new Zend\Loader\ClassMapAutoloader();
$autoloader->registerAutoloadMap($classmapPath);
$autoloader->register();
[/code]

That’s all for tonight folks!

Find MySQL Foreign Keys

January 9th, 2014

Sometimes you need a quick way to find out what foreign key is blocking your action.

[code]SELECT
CONCAT(table_name, ‘.’, column_name) AS ‘foreign key’,
CONCAT(referenced_table_name, ‘.’, referenced_column_name) AS ‘references’
FROM information_schema.key_column_usage
WHERE referenced_table_name IS NOT NULL;[/code]

How to create a HTML tag, using an object of properties.

Javascript HTML Fun

December 18th, 2013

Here are some useful Javascript snips for working with form data.

How to get the name of the HTML tag for an element:
[code]this.nodeName.toLowerCase()[/code]

This code will see if we have a map set of inputs (somename[]):
[code]// See if we have a map here
var mapFound = 0;
if (thisName.indexOf(‘[]’) != -1) {
mapFound = 1;
thisName = thisName.replace(/[\[\]’]+/g, ”);
}[/code]

How to take a map of inputs and turn them into a Javascript map type var, and toss the empty ones:
[code]var map = $(thisName).map(function(){
if (this.value != ”) {
return this.value;
} else {
return null;
}
}).get();[/code]
