CakePHP : DbAcl::allow() - Invalid node [CORE\cake\libs\controller\components\acl.php, line 325]

DbAcl::allow() - Invalid node [CORE\cake\libs\controller\components\acl.php, line 325]
If your following the “Simple Acl Controlled Application” , then you might see the above error message.
A simple fix is, in the function 'initDB()' replace
 $this->Acl->allow($group, 'controllers');
 with
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 1), 'controllers');

So the total function would look like the following:

function initDB() {
 $group =& $this->User->Group;
//Allow admins to everything
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 1), 'controllers');
 //allow managers to posts and widgets
 $this->Acl->deny(array( 'model' => 'Group', 'foreign_key' => 2), 'controllers');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 2), 'controllers/Posts');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 2), 'controllers/Widgets');

//allow users to only add and edit on posts and widgets
 $this->Acl->deny(array( 'model' => 'Group', 'foreign_key' => 3), 'controllers');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 3), 'controllers/Posts/add');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 3), 'controllers/Posts/edit');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 3), 'controllers/Widgets/add');
 $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 3), 'controllers/Widgets/edit');
}

Associating CakePHP files ( *.ctp or *.thtml ) with Eclipse

To set up your version of Eclipse to read either file type( *.ctp or *.thtml), follow these steps

• Go to Window > Preferences > General > Content types
• In the content types window navigate the tree to text > PHP content type
• Click add
• Enter *.ctp or *.thtml depending on what version of CakePHP you use. It might be best to add both - just in case.
• Now navigate to Editors > File Associations
• Enter *.ctp or *.thtml depending on what version of CakePHP you use.
• Under "Associated Editors:", select the PHP Editor and click Default.

Fixing Warning (2): Cannot modify header information - headers already sent by (output started at...

How to fix the following error in PHP

Warning (2): Cannot modify header information - headers already sent by (output started at  ... 

This is also referred to as "whitespace problem".
The error message typically looks something like
Warning (2): Cannot modify header information - headers already sent by (output started at /Library/WebServer/Documents/test-cake/app/models/post.php:1) [CORE/cake/libs/controller/controller.php, line 644]

Steps to resolve the issue:
1) Find the header() statement that is causing the problem. The error must be at or before this line.

2) Identify statements that could send output to the user before this header statement. Example 'echo ' statements. You cannot have these 'echo' statements before header() statement.

3) Make sure there is no white space before the php start and end tags.
Also at the beginning of the file a blank line before the <?php start tag may look innocent, when processed by PHP, it will turn into an echo statement printing out a blank line. This is a common culprit.

Running Tomcat manager when you start the server through eclipse

You can't open the tomcat manager by hitting http://localhost:8080 URL when you start the server through eclipse. This is because the eclipse by default creates the tomcat server instance separate from your installation and uses its custom config files for starting and stopping the tomcat. And also it deploys the webapps under workspace temporary folders (Ex: .metadata\.plugins\org.eclipse.wst.server.core\tmp0). The solutions is to change the default behavior and

You can switch off this default behavior by fallowing the below steps so that you can login to tomcat manager/admin by hitting the http://localhost:8080 URL.
1. Add a new server by right clicking in the servers perspective of your eclipse.
2. Double click on the server added in the above step and change both the server and deploy paths like below.
Server Path : {Tomcat home}
Deploy Path : {Tomcat home}/webapps












3. Start the server.

Note: When you do this, your custom config files will be overwritten in your Tomcat installation each time the tomcat server is started within eclipse. And the manipulation you do through manager/admin will be lost next time the Tomcat server is started in Eclipse.

Mac OS X Fixing Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock'

How to fix Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock'

Apparently, Mac OS X doesn't allow for PHP MySQL connection out of the box. You get this:

    Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock'
OR In CakePHP
Warning: Could not connect to Database.

I found the most clear fix here:

    /etc/php.ini(.default) looks for mysql.sock in the wrong place... two options are to make a symbolic link from the right place to the socket...

    sudo mkdir /var/mysql
    sudo ln -s /private/tmp/mysql.sock /var/mysql/mysql.sock

    Or you can update your php.ini (.default) by finding "mysql.default_socket" and setting it to equal /private/tmp/mysql.sock and then restart apache web server

Cool trick in Windows 7

Create a folder on your desktop or anywhere on your system and then rename it like below:

MasterConsole.{ED7BA470-8E54-465E-825C-99712043E01C}

The icon will change to the control panel icon and you will have access to EVERYTHING from this one spot. It is very cool I think. The “masterconsole” portion of the statement can named differently if you choose to do so.

STEP 4:
-- Open a new Terminal window. Execute the following

Get names of month, weekday of the year for any date value in PHP

To get the names of month, weekday, of the year for any date value in PHP, use the function getDate();

Example:

$datePieces = getDate(strtotime($mydate));

echo "Month name: ".$datePieces['month'];  

echo "Weekday name: ".$datePieces['weekday'];

Make sure to use quotes for the key value like $datePieces['month'] instead $datePieces[month], since it would throw : Notice: Use of undefined constant .... 

The associative array $datePieces contains all of the following:

Array
(
    [seconds] => 40
    [minutes] => 58
    [hours]   => 21
    [mday]    => 17
    [wday]    => 2
    [mon]     => 6
    [year]    => 2003
    [yday]    => 167
    [weekday] => Tuesday
    [month]   => June
    [0]       => 1055901520
)
