Follow This steps :-
Go to Admin => Configuration => Image styles
Then add Custom styles depending on what w=you want ( scale / resize …. ) The save.
And in you module function

$image_thumb = image_style_url('customstyle1', $item -> field_image['und']['0']['uri']);
$image_big_thumb = image_style_url('customstyle2', $item -> field_image['und']['0']['uri']);

Hello,

I have recently moved all my development environment to Mac OS x Lion ( MC 723 )

and i was looking for a lot of alternatives to my windows development stack and IDE ( PHP Designer )

I have tried Zend Server CE but i had a problem getting APC works because different arch x64 !

I have tried MAMP Pro but it sucks as well, i didn’t find it interesting

Finally i have tried using port ! and i really liked it ! and i found it really cool and worth trying ! with good support of almost all and last versions of extensions !

now i have my LAMP Stack UP with phpmyadmin as well !

then when i was looking for a good IDE, I have tried Zend Studio and i find it cool but its bit laggy with huge delay in building functions indexes from files !

I have tried Komodo IDE, it was better than Zend Studio but i didn’t find comfortable in some code completion and highlighting etc ..

Actually i was looking for Replacement for PHP Designer which i consider the most cool IDE in windows !

I have check other in IDE’s but forget all of THEM ! I found PHP Storm ! which beats all the IDE’s i have used till now !

Its Fast, Too much powerful, with very wide range of almost all feature you can ever NEED !!!

I like it and i’m using it in my development stack now !

For UML Diagrams and MySQL Schema tools i found mysql workbench works out of the box ! and i didn’t need for replacements

- The most thing that annoyed me is that I can’t create new files in MAC ! which is really stupid ! i’m using NewDoc now with customized package files to not show it in the Dockbar when launched

- Another things is the Finder !!! no Cut/Multi-Tabs/Show hidden files !!!!! it really miss alot of things !! I’m using Total Finder which i find all what i need in it.

- For SVN I’m using cornerstone which is really powerful and i like it.

I had some pain finding best things that fit my need ! Hope you find this things helpful when you start development in MAC !

Using drupal notification messages for some purposes ( form validations in custom modules )
it was really helpful to use the built in drupal notifications instead of manually writing ones !
Using menu hook in drupal to build customs menus.

function mymoudule_login()
{
    if ($_POST) {
        if (validate_login($_POST['username'], $_POST['password'])) {
            drupal_set_message('You have successfully logged in');
            drupal_goto('mymodule/success');
        } else {
            drupal_set_message('Wrong username or password');
        }
    }
    $messages = drupal_get_messages(); // notification message array()
    $html = $msg['status'][0]; // get the first message that we set
    $html .= '<form method="post">
<input name="username" type="text"><label>Username</label>
<input name ="password" type="password"><label>Password</label>
';
}
 
function validate_login($user, $pass)
{
    //put validation database here or whatever
}

Managing Session Data in Drupal

I was so confused how to to manage the session data in Drupal when i was building some modules !

I looked at the manual and some other articles around and here is what i found

- Drupal session started in bootstrap so you don’t need to start session in you module !

- You can access session data normally via superglobal session array $_SESSION

- To save data in the Session array

ymodule_function_setname($name)
{
    $_SESSION['name'] = $name;
    drupal_save_session();
}
mymodule_function_getname()
{
    return $_SESSION['name'];
}

- There is some other Useful function for session management in Drupal

drupal_save_session	Determines whether to save session data of the current request.
drupal_session_commit	Commits the current session, if necessary.
drupal_session_destroy_uid	Ends a specific users session(s).
drupal_session_initialize	Initializes the session handler, starting a session if needed.
drupal_session_regenerate	Called when an anonymous user becomes authenticated or vice-versa.
drupal_session_start	Forcefully starts a session, preserving already set session data.
drupal_session_started	Returns whether a session has been started.
