我通过创建对象从表单类中获取值。它工作正常。但我想使用静态方法做到这一点。我尝试过但没有成功。
public function display()
{
$newform=new Form();
echo "<pre>";
var_dump($newform->getAll());
var_dump($newform->get('name'));
}
<?php
class Form
{
private $value = array();
function __construct() {
// here you can use some validation or escapes
foreach($_POST as $key=>$value)
$this->value[$key] = $value;
}
public function getAll() {
return $this->value;
}
public function get($value) {
$this->value = $_POST[$value];
return $this->value;
}
}
也许你应该尝试阅读有关静态关键字的PHP文档？
例：
class Form {
private static $value = array();
public static function factory() {
// here you can use some validation or escapes
foreach($_POST as $key => $value) {
static::$value[$key] = $value;
}
}
public static function getAll() {
return static::$value;
}
public static function get($key) {
return static::$value[$key];
}
}
用：
public function display() {
Form::factory();
echo "<pre>";
var_dump(Form::getAll());
var_dump(Form::get('name'));
echo "</pre>";
}
您不会在类外部将函数声明为公共/私有/受保护
你想静态调用这个方法，你可以尝试一下
<?php
function display()
{
$newform=new Form($_POST);
echo "<pre>";
var_dump(Form::getAll());
var_dump(Form::get('name'));
}
class Form
{
private static $value = array();
function __construct(){
// here you can use some validation or escapes
function __constract($array){
foreach($array as $key=>$value)
self::$value[$key] = $value;
}
}
public static function getAll(){
return self::$value;
}
public static function get($value){
self::$value = self::$value[$value];
return self::$value;
}
}
下面是getAll方法的示例。对于get方法，同样的想法：
public function display()
{
var_dump(Form::getAll());
}
class Form
{
private static $value = array();
public static function initPost()
{
foreach($_POST as $key=>$value)
self::$value[$key] = $value;
}
public static function getAll()
{
return self::$value;
}
}
