This article describes the three major automations in ThinkPHP in more detail, which are very important applications, and is shared with you for your reference. The details are as follows:
1. Automatic verification
The format is as follows:
array('Verification Field','Verification Rules','Error prompt','Verification Conditions','Additional Rules','Verification Time')
Parameter description:
Verification field: The form field name needs to be verified
Verification rules: Must be used in conjunction with additional rules
Error prompt: If an error occurs, what kind of error prompt will be thrown to inform the user
Verification conditions: 0, 1, 2
Additional rules: 1. Regex uses regular verification 2. Function uses function verification 3. Callback callback 4. Confirm verify whether the two fields in the form are the same 5. Verify whether they are equal to a certain value 6. Is in within a certain range 7. Verify whether they are unique
TP encapsulation: the require field must be verified; eamil verify the mailbox; url verify the url address; currency; number number;
Verification time: refers to the verification time of the database operation time. Verify Model::MODEL_INSERT when adding new data; Verify Model::MODEL_UPDATE when editing; Verify Model::MODEL_BOTH in all cases;
The page aoli/Home/Tpl/default/User/ is as follows:
<form action="__URL__/regadd" method="post"> username:<input type="text" name="username" /><br /> password：<input type="password" name="password" /><br /> 重复password：<input type="password" name="repassword" /><br /> Registration time：<input type="text" name="createtime" /><br /> registerIP：<input type="text" name="createip" /><br /> <input type="submit" value="register" /> </form>
The page aoli/Home/Lib/Model/ is as follows:
<?php
class UserModel extends Model{//The corresponding table user in the database protected $_validate=array(
array('username','require','Username required'),
array('username','checklen','Username length is too long or too short',0,'callback'),
array('password','require','Password required'),
array('repassword','require','Repeat password required'),
array('password','repassword','The password is inconsistent twice',0,'confirm'),
array('createtime','number','You are not entering a number'),
array('createip','email','The email format is incorrect'),
);
function checklen($data){
if(strlen($data)>15 || strlen($data)<5){
return false;
}else{
return true;
}
}
}
?>
The aoli/Home/Lib/Action/ page is as follows:
<?php
class UserAction extends Action {
function reg(){
$this->display();
}
function regadd(){
$user=D('user');
if($user->create()){
if($user->add()){
$this->success('Registered successfully');
}else{
$this->error('Register failed');
}
}else{
$this->error($user->getError());
}
}
}
?>
2. Automatic completion (autofilling)
Automatic completion is also a member method in ThinkPHP.When creating, it will be automatically executed
The rules are as follows:
array('Fill field','Fill in content','Filling Conditions','Additional Rules');
A simple example is as follows:
protected $_auto = array (
//array( 'status','1'), // When adding, set the status field to 1 array('password','md5',1,'function') , // Make the md5 function handle the password field when it is added array('createtime','time',3,'function' ), // Write the current time stamp to the create_time field when updated);
2. Automatic mapping (field mapping)
Automatic mapping:Map the fields of the database into an alias, and you can use the alias in the form。
A simple example is as follows:
protected $_map = array( 'name' => 'username', 'pass' => 'password', );
The techniques described in this article are of some help to everyone to learn and use ThinkPHP.
