CakePHP learning 2

1 In CakePHP, the control layer automatically searches for the model layer based on its name. For example, by taskcontroller, the model associated with the task
If not associated, you can

<? PHP
Class bookscontroller extends appcontroller {
VaR $ name = 'books ';
VaR $ uses = array ();
Function Index (){
$ This-> set ('page _ heading', 'packt book store ');
$ Book = array (
'Book _ title' => 'object Oriented Programming
With PhP5 ',
'Author' => 'hasin hayder ',
'Isbn '=> '123 ',
'Release _ date' => 'december 2007'
);
$ This-> set ($ book );
$ This-> pagetitle = 'Welcome to the packt book store! ';
}
}
?>

VaR $ uses = array (); indicates that no model is associated. If you want to associate a model, you can
$ Uses = array ('modelname1', 'modelname2 ');

The aboveProgram, The matching template index. thtml is
<H2> <? PHP echo $ page_heading;?> </H2>
<DL>
<LH> <? PHP echo $ booktitle;?> </LH>
<DT> author: </DT> <DD> <? PHP echo $ author;?> </DD>
<DT> ISBN: </DT> <DD> <? PHP echo $ ISBN;?> </DD>
<DT> Release Date: </DT> <DD> <? PHP echo $ releasedate;?> </DD>
</Dl>

You can automatically output the contents of the book array in $ this-> set ($ book); to the page.
'Book _ title' => 'object Oriented Programming

In book_title, the output template on the page is changed to <? PHP echo $ booktitle;?>, There is no underline in the middle.

 

2. Let's look at an example.
<? PHP
Class userscontroller extends appcontroller {
VaR $ name = 'users ';
VaR $ uses = array ();
Function Index (){
If (! Empty ($ this-> data )){
// Data posted
Echo $ this-> data ['name'];
$ This-> autorender = false;
}
}
}
?>

Template:
<? PHP echo $ form-> Create (null, array ('action' => 'index');?>
<Fieldset>
<Legend> enter your name </legend>
<? PHP echo $ form-> input ('name');?>
</Fieldset>
<? PHP echo $ form-> end ('Go');?> .

 

$ This-> data, used to save post data, <? PHP echo $ form-> Create (null, array ('action' => 'index');?> Medium,

Call the formhelper tool method of CakePHP. The first parameter null indicates that it is not bound to any model, and the subsequent array ('action' => 'index');?>

Indicates that you want to use index () in the controll layer ().

Echo $ this-> data ['name'];
$ This-> autorender = false;

, $ This-> data ['name']; output result, $ this-> autorender = false; set the output result in the controll layer and do not bind the output to the view.

 

3 redirect jump
Class userscontroller extends appcontroller {
VaR $ name = 'users ';
VaR $ uses = array ();
Function Index (){
If (! Empty ($ this-> data )){
$ This-> redirect (Array ('controller' => 'users ',
'Action' => 'Welcome ', urlencode ($ this-> data ['name']);
}
}
Function welcome ($ name = NULL ){
If (empty ($ name )){
$ This-> session-> setflash ('Please provide your name! ', True );
$ This-> redirect (Array ('controller' => 'users ',
'Action' => 'index '));
}
$ This-> set ('name', urldecode ($ name ));
}
}

Here, if a parameter is submitted on the page, use redirect to jump to the welcome action in userscontroller and pass the parameter name.

 

 

4. You can write a base class in the app, for example

Class appcontroller extends controller {

....

}

Put it in the app directory

And other inheritance
Class bookscontroller extends appcontroller {

...

}

 

5 CakePHP Components
In the component directory of controll, write the util. php component.
<? PHP
Class utilcomponent extends object
{
Function strip_and_clean ($ id, $ array ){
$ Id = intval ($ id );
If ($ id <0 | $ id> = count ($ array )){
$ Id = 0;
}
Return $ ID;
}
}
?>

To use
Class bookscontroller extends appcontroller {
VaR $ name = 'books ';
VaR $ uses = array ();
VaR $ components = array ('util ');

$ Id = $ this-> util-> strip_and_clean ($ id, $ books );
