Mininal use of $uses variable to load models
CakePHP loads all models specified in var $uses array when a controller action is called. By loading a model cakephp creates the schema/structure of the table and also caches it for further use in the application.
Let say you specify four models in the var $uses. Now every time you call a controller action, all four models will be loaded irrespective of any of four being used by controller action or not. For example, Continue reading
Cakephp framework provides a strong model validation mechanism. Here is the quick overview of multiple validation rules applied to a single field.
Let say we are using “User.password” and “User.password2” fields to accept/confirm password while registering to a site. We have “password2” field which is supposed to contain non-empty characters as well as the same password entered in the “password” field. Continue reading
I tried to enable “show hidden files and folder” option in my window xp but after clicking “apply” and “ok” when i returned back to the folder to view hidden files it did not show the hidden files. I tried once again and then again but it did not work. The changes would just disappear upon opening the dialog again. Continue reading
I was struck in a very strange problem today. I was using captcha component to create and set a captcha session and image for view section. Next is the snippet of create function which i used to load component. I will be pasting JcaptchaComponent source code at the end for anyone who may want to take a look into the matter more precisely (however i feel the componet itself should be quite innocent) Continue reading

While working with a CJ run reports script i needed to convert “month name” into “month number” so i could store it in the database in date format. After doing some cleaning stuff i was ending with the month name, a three character string as “Jan”,”Mar”,”Apr” etc. Here is the quick work around i applied to get the month number automatically from the month name.
$month_name = "Jan"; //which i get from file name (Range_from_1_Jan_2009_to_3_Mar_2009.txt)
$month_number = "";
for($i=1;$i<=12;$i++){
if(strtolower(date("M", mktime(0, 0, 0, $i, 1, 0))) == strtolower($month_name)){
$month_number = $i;
break;
}
}
Now as php snippet code line 5 date(“M”, mktime(0, 0, 0, 1, 1, 0))) returns a three letter represantion of month name i get month “1” if i pass $month_name=”Jan” and so on. If i had full month name like “January” i could make it work by replacing “M” with “F” where “F” format parameter is a full represantion of year name.
