Drupal: Form Validation Messages Order

27 July 2017, in

Hello all Drupalists,

Have you ever had a problem with form validation messages order, ... I think we all had this issue.

For some reason validation messages are not ordered the right way (with the same order as the form fields).

For this reason, I wrote the below code to be used to reorder form validation messages.

Note that the below code also has a function to be used if you are using conditional fields module to manage field dependencies.

Javascript: have variable variables

26 November 2013, in

In PHP to have "Variable" variables.

For example

$x = "variable";

$$x = "hello, world!";

echo $variable;" //"hello, world!"

So as a workaround you can do as the following:

var obj = {} = 42;

var bar = 'foo';

PHP - Ubuntu: supported locales

26 November 2013, in

1. First of all list supported locales:

cat /usr/share/i18n/SUPPORTED

2. Copy the locales for your region. I will copy the following lines:

sv_SE.UTF-8 UTF-8

sv_SE ISO-8859-1

3. Edit the list of 'supported locales' and paste your locales that you've copied. (See step above)

gedit /var/lib/locales/supported.d/local

PHP: Problem getting date in different locale

26 November 2013, in

Have you ever faced a problem trying to get date in another locale ?

The way you can do it right is as follows:

You will use set setlocale(), strftime()

suppose you want to get the date in Italian

setlocale(LC_ALL, 'it_IT'); // Set locale to Italian

echo strftime("%e %B %Y"); //today's date

echo strftime("%e %B %Y",strtotime($date)); //another date

CakePHP: change default model for a controller

30 November 2012, in

By default a CakePHP controller uses a model with singularized name, for example a controller with name Students will use by default a model named Student,

But if you want or have to change the default model for a controller you can set it using

$modelClass member attribute

for example for a controller named ClassesController and you can't name the model class with name "Class" because it is a keyword in PHP, and you decided to change the model name to Classroom

Class ClassesController extends AppController {

$modelClass = 'Classroom';

PHP: check string has HTML tags

25 November 2012, in

you may think as the best way to check a string has HTML tags is to check the string after stripping tags:

if( strlen($string) != strlen(strip_tags($string)) ){

echo 'Contains HTML tags';


But, the best way is to use regular expressions:

if (preg_match("/([\<])([^\>]{1,})*([\>])/i", $string )) {
echo 'Contains HTML tags';
