A model layer
<? PHP
Class task extends appmodel {
VaR $ name = 'task ';
VaR $ validate = array (
'Title' => array (
'Rule' => valid_not_empty,
'Message' => 'title of a task cannot be empty'
)
);
}
?>

B control layer

<? PHP
Class taskscontroller extends appcontroller {
VaR $ name = 'tasks ';
VaR $ helpers = array ('html', 'form', 'time ');

 

Function Index ($ status = NULL ){
If ($ status = 'done ')
$ Tasks = $ this-> task-> Find ('all', array ('conditions' =>
Array ('task. done' => '1 ')));
Else if ($ status = 'Pending ')
$ Tasks = $ this-> task-> Find ('all', array ('conditions' =>
Array ('task. done' => '0 ')));
Else
$ Tasks = $ this-> task-> Find ('all ');
$ This-> set ('tasks', $ tasks );
$ This-> set ('status', $ status );
}

 

Function add (){
If (! Empty ($ this-> data )){
$ This-> task-> Create ();
If ($ this-> task-> Save ($ this-> data )){
$ This-> session-> setflash ('the task has been saved ');
$ This-> redirect (Array ('action' => 'index'), null, true );
} Else {
$ This-> session-> setflash ('Task not saved. Try again .');
}
}
}

Function edit ($ id = NULL ){
If (! $ Id ){
$ This-> session-> setflash ('invalidtask ');
$ This-> redirect (Array ('action' => 'index'), null, true );
}
If (empty ($ this-> data )){
$ This-> DATA = $ this-> task-> Find (Array ('id' => $ id ));
} Else {
If ($ this-> task-> Save ($ this-> data )){
$ This-> session-> setflash ('the task has been saved ');
$ This-> redirect (Array ('action' => 'index'), null, true );
} Else {
$ This-> session-> setflash ('the task could not be saved.
Please, try again .');
}
}
}

Function Delete ($ id = NULL ){
If (! $ Id ){
$ This-> session-> setflash ('invalid for task ');
$ This-> redirect (Array ('action' => 'index'), null, true );
}
If ($ this-> task-> Del ($ id )){
$ This-> session-> setflash ('Task # '. $ id. 'deleted ');
$ This-> redirect (Array ('action' => 'index'), null, true );
}
}

}
?>
C view layer
Create a sub-directory tasks under the view directory
Index. thtml:
<H2> tasks </H2>
<? PHP if (empty ($ tasks):?>
There are no tasks in this list
<? PHP else:?>
<Table>
<Tr>
<TH> title </Th>
<TH> Status </Th>
<TH> created </Th>
<TH> modified </Th>
<TH> actions </Th>

<? PHP foreach ($ tasks as $ task):?>
<Tr>
<TD>
<? PHP echo $ task ['task'] ['title']?>
</TD>
<TD>
<? PHP
If ($ task ['task'] ['done']) echo "done ";
Else echo "pending ";
?>
</TD>
<TD>
<? PHP echo $ time-> niceshort ($ task ['task'] ['created '])?>
</TD>
<TD>
<? PHP echo $ time-> niceshort ($ task ['task'] ['modified'])?>
</TD>
<TD>
<? PHP echo $ HTML-> Link ('edit', array ('action' => 'edit ',
$ Task ['task'] ['id']);?>

Add. thtml:
<? PHP echo $ form-> Create ('task');?>
<Fieldset>
<Legend> Add new task </legend>
<? PHP
Echo $ form-> input ('title ');
Echo $ form-> input ('done ');
?>
</Fieldset>
<? PHP echo $ form-> end ('add task');?>
<? Echo $ HTML-> Link ('list all tasks ', array ('action' => 'index');?>

Edit.html:
<? PHP echo $ form-> Create ('task');?>
<Fieldset>
<Legend> edit task </legend>
<? PHP
Echo $ form-> hidden ('id ');
Echo $ form-> input ('title ');
Echo $ form-> input ('done ');
?>
</Fieldset>
<? PHP echo $ form-> end ('save');?>
<? PHP echo $ HTML-> Link ('list all tasks ', array ('action' =>'
Index');?> <Br/>
