Practical Essentials of curd application in thinkphp _php techniques

This is the main leisure to write about the specific application of curd, of course, the main side of the curd, I do is the user's additions and deletions, not with the three automatic

First of all

Copy Code code as follows:

Class Indexaction extends Action {
Public Function index () {
Header ("content-type:text/html; Charset=utf-8″);
$user =m (' user ');
$list = $user->select ();
$this->assign (' user ', $list);
$this->display ();
}

Show all users, homepage do registration

Copy Code code as follows:

Form action= "__url__/add" method= "POST" >
User name <input type= "text" name= "username" >
Password <input type= "text" name= "password" >
<input type= "Submit" value= "submitted" >
</form>
<volist name= "user" id= "VO" >
User name: <input name= "username" value= "<{$vo .username}>" >
Password: <input name= "password" value= "<{$vo .password}>" >
Registered Ip:<input name= "CIP" value= "<{$vo .cip}>" >
Registration time: <input name= "CTime" value= "<{$vo .ctime}>" >
<a href= "__url__/del/id/<{$vo .id}>" > Delete </a>
<a href= "__url__/edit/id/<{$vo .id}>" > Update </a>
<br>
</volist>

And then there is our deletion method is very simple thinking is like this we get ID delete this ID is ok

Copy Code code as follows:

if ($user->where (' $_get[' id ') ')->delete ())

{
$this->success (' delete success ');
}

That's it, okay?

Ways to add Users

Copy Code code as follows:

$user =m (' user ');
if ($user->create ()) {
$user->cip=get_client_ip ();
$user->ctime=time ();
$user->password=md5 (' password ');
if ($user->add ($data)) {
$this->success (' User registration Success ', '/admin.php/index/edit ');
}else{
$this->error ($user->geterror ());
}
}else{
$this->error (GetError ());
}

The update user is like this, we choose the user output information according to the ID

Copy Code code as follows:

$user =m (' user ');
$id = (int) $_get[' id '];
$user =m (' user ');
$list = $user->where ("id= $id")->find ();
$this->assign (' list ', $list);
$this->display ();

And then updating the user is simpler just one save

Copy Code code as follows:

$user =m (' user ');
if ($user->create ()) {
$user->ctime=time ();
if ($user->save ()) {
$this->success (' update successful ');
}
}else{
$this->error (' failure ');
}

This is the end of these parts will be able to complete the user's additions and deletions in fact, the simple function is our own added to the example

We go to the forum have landed how many times how to complete the fact that a setinc can be resolved landing once +1 such output landing

The number of times is OK

Here we go today.
