I am running my machine with nginx & php 5.6, First make sure that you have already installed Xdebug. We can check this with php version command
$ php -v
If you see ‘Xdebug v’ that means XDebug installed. If you do not see then install XDebug using PECL
$ pecl install xdebug
If the extension is added to your php.ini file automatically, remove the following line:
zend_extension_ts="xdebug.so"
And replace it with:
zend_extension="/usr/local/php/lib/php/extensions/no-debug-zts-20131226/xdebug.so"
Restart your nginx and confirm XDebug is installed by checking php version OR you can also check with phpinfo in the browser.
Note =: to find php.ini or xdeboug.so use $ locate or check phpinfo for php.ini location.
Open PhpStorm -> File -> Default Settings -> In the search box search with ‘debug’
Change ‘Debug port’ to 9001, apply and ok.
Open File -> Default Settings -> Search for ‘IDE Key’
Set IDE key as ‘PHPSTORM’, Apply & OK
Now we need to add following XDebug values in php.ini, restart nginx & php-fpm
xdebug.remote_port=9001 xdebug.remote_enable=1 xdebug.idekey=PHPSTORM
Enable google chrome extension Xdebug helper
Once you have enabled extension then you need to add Debugger bookmarklets for chrome. Go to https://www.jetbrains.com/phpstorm/marklets/ page & Generate XDebugger bookmarks
Note : IDE key should be PHPSTORM, as we set in PhpStorm settings.
Now Drag & drop - Start debugger & Stop debugger to chrome bookmarks Bar. You should see the screen like below
Now it’s time to debug our drupal 7 site with phpstorm & chrome
Open PhpStorm with drupal 7 project & click ‘Start listen for PHP Debug connections’ (These option are at Top Right corner)
Now open google chrome browser & click on ‘Start debugger’ in the bookmark toolbar.
Now add breakpoint in index.php file in PhpStorm.
Then again visit chrome and load any page of these project (localhost/drupal7). For the first time phpstorm will ask for confirmation dialogue box to accept connection from google chrome. Once you accept it, you will see debug information like below.
Now you can debug by putting multiple breakpoints on your code.

I have been working on Drupal 7 for almost two years now. During these two years I have worked on many hooks but hook_menu_alter() hook is the one of the mostly used one. Today i going to explain my experience with this hook.
I have discussed this one of earlier post in detail. There we have used hook_custom_theme() hook to change theme on particular page. Instead of this we can also use hook_menu_alter() as another way to achieve same feature.
/*
* Implements hook_menu_alter().
*/
function custom_module_menu_alter(&$items){
// Change 'node/add/page' page to admin theme (Assume by default node/add page uses default theme)
$items ['node/add/page']['theme callback'] = variable_get('admin_theme');
}
Menu provides page titles. If we are in ‘node/add/page’ then we see page title as ‘Create Basic page’ but what if we need custom title like ‘Add page’. We can achive this using below custom module.
/*
* Implements hook_menu_alter().
*/
function custom_module_menu_alter(&$items){
// Change 'node/add/page' title to 'Add page'
$items ['node/add/page']['title'] = 'Add Page';
}
For many pages/menus we restrict access to different users or on conditions. Let’s say we want restrict ‘user/register’ page in particular times.. I mean no registration will be done in 12AM - 06AM.
/*
* Implements hook_menu_alter().
*/
function custom_module_menu_alter(&$items){
// Restrict 'user/register' page in 12AM-05AM
$items ['user/register']['access callback'] = '_MY_MODULE_time_access';
}
/*
* Access callback function to restrict user registration in particular timings
*/
function custom_module_time_access(){
// Get current time hour like 0,1,2,3....23
$current_time_hour = date('G');
// if current time is between 0 & 5 then return false
if($current_time_hour >= 0 && $current_time_hour <= 5 ){
return false;
}
return TRUE;
}
We can also use hook_menu_alter() hook if we want to create a duplicate page, a page with same functionality but with different url. Let’s say we want a url ‘add/page’ which acts same as of ‘node/add/page’.
/*
* Implements hook_menu_alter().
*/
function custom_module_menu_alter(&$items){
// Copy ‘node/add/page’ page to ‘add/page’
$items ['add/page'] = $items ['node/add/page'];
}
In drupal 7 whenever admin selects to cancel user/s account, it provides multiple cancellation options like
In this post I am going to explain how to create a create custom method like ‘Disable the account and make its content belong to the admin user.’
There are two user API hooks available to achieve this - hook_user_cancel_methods_alter() & hook_user_cancel(). Before we start implementing lets discuss about these hooks.
This hook is used to modify account cancellation methods and can be used to add, customize, or remove account cancellation methods. After we invoke this hook all defined methods are converted as radio button form elements by user_cancel_methods() We can define following 3 properties -
In our case we are defining new method called ‘my_module_assign_to_admin’
These hook will be called on user account cancellations. Depending on the account cancellation method, the module should either do nothing, unpublish content, or anonymize content. In this case also following 3 properties can be defined -
In our case we are defining functionality for our method ‘my_module_assign_to_admin’
Let’s create module called my_module, using following code
/*
* Implements hook_user_cancel_methods_alter().
*/
function my_module_user_cancel_methods_alter(&$methods) {
// Add a custom method.
$methods['my_module_assign_to_admin'] = array(
'title' => t('Disable the account and make its content belong to the admin user.'),
'description' => t('All contents will be assigned to admin user.'),
// access should be used for administrative methods only.
'access' => user_access('Administer permissions'),
);
}
/*
* Implements hook_user_cancel().
*/
function my_module_user_cancel($edit, $account, $method) {
switch ($method) {
case 'my_module_assign_to_admin':
// Assign nodes to admin user.
module_load_include('inc', 'node', 'node.admin');
$nodes = db_select('node', 'n')
->fields('n', array('nid'))
->condition('uid', $account->uid)
->execute()
->fetchCol();
node_mass_update($nodes, array('uid' => 1));
break;
}
}
Just enable this module on your module list page, you should see additional option for user cancellation -

One of the great feature in drupal is tokens system. Tokens are reusable text that can be placed into documents via simple placeholders, like %site-name or [user]. In Drupal there are many default tokens are made available thru’ token module e.g. nodes, users, taxonomy as well as other site related tokens. For example to display site name we have [site:name] token, to display node author we have [node:author]. All these tokens are properties of entities. And if we add new field in node then these field will be available as token. For example [node:body] is the token where it will display body field.
But quite a few times we come across situation when default tokens available in Drupal is not enough for project. Today we are going to discuss about how to create custom tokens using our custom module. In our example we will create a token Trimmed body field. This will display 20 characters of body field in a node wherever we will use this token.
To achieve these we will be using hook_token_info() and hook_tokens() hooks Create a new module MY_MODULE and implement these two hooks. But before start implementing this let’s discuss about hook_token_info() and hook_tokens() hooks.
These hook provides information about available placeholder tokens and token types. Tokens are placeholders that can be put into text by using the syntax [type:token], where type is the machine-readable name of a token type, and token is the machine-readable name of a token within this group.
Return value properties:
These function will return associative array of available tokens and token types.
types
tokens
These hook provides replacement values for placeholder tokens. This hook is invoked when someone calls token_replace(). That function first scans the text for [type:token] patterns, and splits the needed tokens into groups by type.
Return value properties :
$type: The machine-readable name of the type (group) of token being replaced, such as 'node', 'user', or another type defined by a hook_token_info() implementation.
$tokens: An array of tokens to be replaced. The keys are the machine-readable token names, and the values are the raw [type:token] strings that appeared in the original text.
$data: (optional) An associative array of data objects to be used when generating replacement values, as supplied in the $data parameter to token_replace().
$options: (optional) An associative array of options for token replacement; see token_replace() for possible values.
Create MY_MODULE module & create file MY_MODULE.tokens.inc and implement following code.
/**
* Implements hook_token_info().
*/
function custom_title_token_info() {
// Define token value, body_trim is the token will be used as [node:body_trim]
$node_trim['body_trim'] = array(
'name' => t("Trimmed body field"),
'description' => t("Trim body field to 20 characters "),
);
// Return associative array of tokens & token types
return array(
'tokens' => array(
'node' => $node_trim,
),
);
}
/**
* Implements hook_tokens().
*/
function custom_title_tokens($type, $tokens, array $data = array(), array $options = array()) {
$replacements = array();
// Check if token type is node
if($type == 'node'){
foreach ($tokens as $name => $original) {
switch ($name) {
// Check token is body_trim
case 'body_trim':
$body = $data['node']->body[LANGUAGE_NONE][0]['value'];
// Trim 20 characters and return
$replacements[$original] = substr($body,0,20) . ' ...';
break;
}
}
}
return $replacements;
}
Note : We have not defined any custom token type as we needed node related token.

function hook_token_info
function hook_tokens
In drupal 7 we have options to set default theme & admin theme. There are limitations, Admin theme will be available for roles which has access permission for admin theme. But in case if we have conditions to set specific theme for specific page based on user roles or specifying theme for particular node types, drupal core will not provide options to do these. We do have module available for this purpose - ThemeKey. But we can achieve by using drupal hooks also.
In this post I am going to explain how we can change particular theme for different pages based on various conditions. Let’s take following scenarios.
Note : By default manager role is not set admin theme.
Drupal 7 provides hook_custom_theme() hook to do these functionality. Let’s create module called dynamic_theme. Check implementation of hook_custom_theme() for above scenarios.
/**
* Implements hook_custom_theme().
*/
function dynamic_theme_custom_theme() {
// Load current user
global $user;
// Check current page is 'node/%nid%/nid'
if(current_path() == 'node/%node/edit'){
// Check current user role is 'manager'
$roles = $user->roles;
if(in_array('manager',$roles)){
// return admin theme for these page
return variable_get('admin_theme');
}
}
}
/**
* Implements hook_custom_theme().
*/
function dynamic_theme_custom_theme() {
// Load current user
global $user;
// Check current page is 'node/%nid%/nid'
if(current_path() == 'node/add/article'){
// Check current user role is 'manager'
$roles = $user->roles;
if(in_array('manager',$roles)){
// return default theme for these page
return variable_get('theme_default');
}
}
}
In case if we have multiple themes then return theme name in these function.
Note : The theme you want to activate must be enabled.

As a drupal developer we use drush on daily basis. For example clearing the cache, downloading or enabling modules/themes, updating modules. All these commands comes with core but drupal also provides hooks to integrate with our custom modules.
Today we are discussing about how we can write drush commands through our custom module. We are taking example - “Count of nodes by type”.
$ drush node-countor $ drush nc
Example of using & output:
$ drush node-count article article’s node count : 100
To achieve these we have to hook_drush_command(). Let’s create module called custom_dc, And check these code.
/**
* Implementation of hook_drush_command().
*/
function custom_title_drush_command() {
$items = array();
$items['node-count'] = array(
'callback' => 'custom_title_node_count', // Callback function
'description' => 'Drush command to get node count of particular node type.',
'aliases' => array('nc'), // alias of command
'examples' => array( // List these example when user types : drush help nc
'Get all nodes count' => 'drush nc',
'Get articles node count' => 'drush nc article',
'Get articles, pages node count' => 'drush nc article page',
),
);
return $items;
}
/*
* Callback function for hook_drush_command().
*/
function custom_title_node_count() {
// Get arguments passed in command, Ex: drush nc page blog
$args = func_get_args();
if ($args) {
// Loop for types
foreach($args as $type){
// Query to get count of particular type
$result = db_select('node', 'n')
->fields('n', array('nid'))
->condition('type', $type, '=')
->execute();
$num_of_results = $result->rowCount();
drush_print($type. "'s node count : " . $num_of_results);
}
}
// If no type passed then return total count
else {
drush_print('No node types mentioned');
$result = db_select('node', 'n')
->fields('n', array('nid'))
->execute();
$num_of_results = $result->rowCount();
drush_print('Count of all nodes : '. $num_of_results);
}
}
This hook defined command “node-count”.
Some points about hook_drush_command() implementation.
$ drush help nc Drush command to get node count of particular node type. Examples: Get all nodes count drush nc Get articles node count drush nc article Get articles, pages node count drush nc article page Aliases: nc
How to use newly created drush commands - Get all nodes count
drush nc
Get article nodes count
drush nc article
Get page nodes count
drush nc page
Get page, blog nodes count
