I wanted one of my web applications to have a different appearance on mobile phones and devices. I didn’t really want to set up an entirely different domain or use a sub domain particularly for mobile devices (like http://mobile.facebook.com).

CakePHP – Search for records between two dates inclusively

Often we search for records in a database table for fetching records that were created or modified on a particular date or between two dates. We match against a date field and add multiple conditions to find records with a date field value ranging between two dates.

Swap Values Without Temp or A Third Variable in PHP

When we need to swap the values of two variables, we use a third variable temporarily to hold the data between swapping.  Something like this:

<?php
$tmp = $a;
$a = $b;
$b = $tmp;
?>

Here is another way without using a temp or a third variable.

<?php
list($b, $a) = array($a, $b);
?>

And if you want to make it a function:

<?php
function swapValues(&$a, [...]

CakePHP – Accessing a model in AppController or in any Controllers

Sometimes, or very rarely we might need to access a model in AppController (Application Controller). This could be for fetching values from a table and make it available for all the controllers in the application (AppController is inherited by all the other controllers). Also, often we need to access models that are not associated with [...]

Joining multiple tables in CakePHP using bindModel method

One of the most powerful features of CakePHP is the ability to link relational mapping provided by the model. In CakePHP, the links between models are handled through associations. The associations are defined in the models as hasOne, hasMany, belongsTo etc. It is possible to define deep relationships involving many tables and retrieve data. But CakePHP doesn’t always form a single query to associate many tables and retrieve records. Often it joins a couple of tables first and look in the other tables matching the IDs of the first query result. So a multiple join association is achieved through more than one queries. This method often troubles you when you want to do a search in fields across multiple tables.
