CakePHP study summary 6

1. Change the debug information in the lower part of the cake during running.
Set row 43rd of APP \ config \ core. php
* Development Mode:
* 1: errors and warnings shown, model caches refreshed, flash messages halted.
* 2: As in 1, but also with full debug messages and SQL output.
* 3: As in 2, but also with full controller dump.
*
* In production mode, flash messages redirect after a time interval.
* In development mode, you need to click the Flash message to continue.
*/
Configure: Write ('debug', 2 );
Change to configure: Write ('debug', 0 );

2. Change http: // localhost: 8082/myphp5/quickwall/home
Http: // localhost: 8082/myphp5/quickwall,
Change app \ config \ route. php
Router: connect ('/', array ('controller' => 'questions', 'Action' => 'home '));

3 For example, writing a user-defined validator
In usermodel
Function checkunique ($ data, $ fieldname ){
$ Valid = false;
If (isset ($ fieldname) & $ this-> hasfield ($ fieldname )){
$ Valid = $ this-> isunique (Array ($ fieldname => $ data ));
}
Return $ valid;
}

'Unique' => array (
'Rule' => array ('checkunique', 'username '),
'Message' => 'user name taken. Use another'
)

4 function beforefilter (){
$ This-> auth-> allow ('signup ');
}
The filter is executed before each action, as in Java. Allow allows actions to be executed without auth authentication.

 

5
Write an app_controller.php file in the app directory. Other classes inherit it.
Function beforefilter (){
$ This-> auth-> loginredirect = array ('controller'
=> 'Questions', 'Action' => 'home ');

$ This-> auth-> logoutredirect = array ('controller'
=> 'Questions', 'Action' => 'home ');

$ This-> auth-> allow ('signup', 'Confirm', 'home', 'show ');
$ This-> auth-> authorize = 'controller ';
$ This-> auth-> userscope = array ('user. Confirmed '=> '1 ');
$ This-> set ('loggein', $ this-> auth-> User ('id '));
}

Function isauthorized (){
Return true;
}

Here, $ this-> auth-> loginredirect, $ this-> auth-> logoutredirect indicates that the login is successful and the exit path is reached.
Userscope indicates that logon is allowed only when a condition is set. Otherwise, logon is not allowed.
$ This-> set ('loggein', $ this-> auth-> User ('id'); Put the user ID after logon to loggedin for ease of use at the view layer.
For example, in the template

<? PHP if ($ loggedin):?>
.....
<? PHP else?>
.....
<? PHP end if;?>

Isauthorized () is required. You can write some functions that have been successfully verified. If not, return true.

Login and logout in user_controll can be written in this way.
Function login (){
}

Function logout (){
$ This-> session-> setflash ('logout ');
$ This-> redirect ($ this-> auth-> logout ());
}

6. Use cookies
<? PHP
Class appcontroller extends controller {
VaR $ components = array ('auth ', 'cooker ');
...
In appcontrol, Set
$ This-> auth-> autoredirect = false;
$ This-> cookie-> name = 'quickwall ';

If (! $ This-> auth-> User ('id ')){
$ Cookie = $ this-> cookie-> Read ('user ');
If ($ cookie ){
$ This-> auth-> login ($ cookie );
}
}

 

$ This-> auth-> autoredirect defaults to true. Here, false indicates that after successful login,
To go to login, it is
Function login (){
If ($ this-> auth-> User ()){
If (! Empty ($ this-> data )){
If (empty ($ this-> data ['user'] ['Remember _ me']) {
$ This-> cookie-> Del ('user ');
} Else {
$ Cookie = array ();
$ Cookie ['username'] = $ this-> data ['user']
['Username'];
$ Cookie ['Password'] = $ this-> data ['user']
['Password'];
$ This-> cookie-> write ('user', $ cookie, true,
'+ 2 weeks ');
}
Unset ($ this-> data ['user'] ['Remember _ me']);
}
$ This-> redirect ($ this-> auth-> redirect ());

 

7. Use Javascript
Add helper, for example, in appcontroller:
VaR $ helpers = array ('html', 'form', 'javascript ');
Add
<? Php e ($ JavaScript-> Link ('prototype-1.6.0.2 ');?>
<? Php e ($ scripts_for_layout);?>
Put prototype. js and so on under the APP/webroot/JS directory
