Learn PHP today, see many people on the Internet recommended cakephp, download to try it. Here are the notes I recorded, the entry level. If my understanding and description of the wrong place, please help me to point out, thank you!
1. Download and install cakephp
2. Create database phptest, data table users
3, connect the database, app/config/database.php
Public$default=array (' datasource ' = ' database/mysql ',//database type
' Persistent ' =>false, ' host ' = ' localhost ',//hostname
' Login ' = ' root ',//user name
' Password ' = ' root ',//password
' Database ' = ' phptest ',//DB name ' prefix ' = ' + '/' encoding ' + ' UTF8 ',);
4, create model,app/model/user.php. Note that PHP has strict naming conventions, and the data tables are in the plural form, such as Users,model, with the singular form of the table name as user, CakePHP automatically associates the Users data table, user model, Userscontroller controller, and users/***. The CTP view.
<?php
Class User extends appmodel{
var $name = ' User ';//specifying the name of the model in the $name is a recognized best practice.
var $useTable = ' users ';//This sentence is not, the default is to connect the Users data table
}
?>
5. Create the Controller controller,app/controller/userscontroller.php
<?php
Class Userscontroller extends appcontroller{
var $name = ' Users ';
Function Show () {
$this->set (' Users ', $this->user->find (' all ')); Pass the value of users to the view through the Set function
}
}
?>
6. Create a View VIEW,APP/VIEW/USERS/SHOW.CTP
<! DOCTYPE html>
<meta charset= "Utf-8"/>
<title></title>
<body>
<table>
<tr>
<th>id</th><th>username</th><th>password</th>
</tr>
<?php foreach ($Users as $User):?>
<tr>
<td><?php echo $User [' User '] [' id '];?></td>
<td><?php echo $this->html->link ($User [' User '] [' username '], '/users/view/'. $User [' user '] [' id ']); ></td>
<td><?php echo $User [' User '] [' password '];?></td>
</tr>
<?php Endforeach;? >
</table>
</body>
Displays the users list with the table element, the foreach ($Users as $User) loop the Users object, $User [' model name '] [' property '] to get the properties of the object. $this->html->link (display content, URL) Link, cake1.3 version before the use of $html->link, the new version uses $this->html->link.
7. Run test, browser url:http://localhost:16418/users/show, Access Controller/userscontroller Show method, jump to VIEW/SHOW.CTP view
8, Perfect function, click the username link of the list to jump to the new view display user information. Query by ID.
A, add the view method in Userscontroller.php, the method name is the same as the URL in link.
Function view ($id =null) {
$this->user->id= $id;
$this->set (' User ', $this->user->read ());
}
B. Create VIEW.CTP in view
<body>
<?php echo "ID:". $User [' User '] [' ID ']. <br> ";?>
<?php echo "Username:". $User [' User '] [' Username ']. " <br> ";?>
<?php echo "Password:". $User [' User '] [' Password ']. " <br> ";?>
</body>
After clicking the link, the results are displayed as
9. New
Userscontroller.php Adding the Add method
function Add () {
if (!empty ($this->data)) {
if ($this->user->save ($this->data)) {
$this->redirect (Array (' action ' = ' show '));
}else{
$this->redirect (Array (' action ' = ' show '));
}
}
}
New View ADD.CTP
<form action= "/users/add" method= "POST" >
<label>username:</label><input name= "username" size= "/>"
<label>password: </label><input type= "password" name= "password" size= "+"/>
<input type= "Submit" value= "Submission"/>
</form>
Model user.php Adding validation rules
Set up validation rules for new user
var $validate =array (
"Username" =>array ("rule" = "notempty"),
"Password" =>array ("rule" = "notempty")
);
Add unsuccessful if the form content does not conform to the validation rule
does not conform to the "username" =>array ("rule" = "notempty") This validation rule, so failed.
10. Delete
userscontroller.php Adding a Delete method
function Delete ($id =null) {
$this->user->delete ($id);
$this->session->setflash ("Success");
$this->redirect (Array ("action" = "show"));
}
Modify View SHOW.CTP
<td><?php Echo $this->html->link ("delete", Array (' action ' = ' delete ', $User [' User '] [' ID ']), NULL, ' Are you sure you want to delete it? ')?></td>
Link ("Delete", Array (' Action ': ' delete ', parameter), NULL, prompt statement)
