[英]Form inputs to class properties
I'm trying to learn OO PHP and I'm working on a contents manager project, I want to construct an object starting from an html form. 我正在尝试学习OO PHP,并且正在从事内容管理器项目,我想从html表单开始构造一个对象。
For example, if I have a form with ten textbox (or other types of input), I sent the form in POST mode, then I want to construct my object starting from POST data. 例如,如果我有一个包含十个文本框的表单(或其他类型的输入),则以POST模式发送该表单,那么我想从POST数据开始构建对象。
Do I have to pass them as constructor's parameters, or as an array? 我是否必须将它们作为构造函数的参数或数组传递? How?
怎么样?
Just an example: 只是一个例子:
My little form: Name, Surname, Description (but there might be over ten inputs) 我的小表格:名称,姓氏,描述(但可能有十多个输入)
My $_POST array: ('name'=>'Mario', 'surname'=>'Rossi', 'description'=>'Just a description here.') 我的$ _POST数组:(“名称” =>“马里奥”,“姓氏” =>“罗西”,“描述” =>“仅在此处进行描述。”)
My class: 我的课:
class Person {
private $name;
private $surname;
private $description;
public function __contruct(/*arguments or array here*/) {
}
}
A clean and easy solution is to use the json_decode
and json_encode
functions. 一个干净而简单的解决方案是使用
json_decode
和json_encode
函数。
http://php.net/json_decode http://php.net/json_decode
$object = json_decode(json_encode($_POST['formdata']), FALSE);
json_decode
converts your formdata to an serialized object and the second parameter of json_encode
(false) prevents the data from being converted back to an array
. json_decode
将您的json_decode
转换为序列化的对象,而json_encode
的第二个参数(false)可防止将数据转换回array
。
Don't directly use $_POST
in the function rather send it as parameter to the function 不要在函数中直接使用
$_POST
而是将其作为参数发送给函数
Function call from CLASS object: 从CLASS对象调用函数:
$args = array(
'val1' => $_POST['val1'],
'val2' => $_POST['val2'],
'val3' => $_POST['val3']
);
$obj->funct($args);
Function definition in CLASS: CLASS中的函数定义:
public function funct ($param = array()) {
print_r( $param );
}
If your form has data beyond one Person
, then one Person
is not enough to represent your form! 如果您的表单中的数据超过一个
Person
,那么一个Person
不足以代表您的表单!
Have a class PersonForm
(or whatever name it may be), and pass in the $_POST
array as an argument. 有一个
PersonForm
类(或它的任何名字),并传入$_POST
数组作为参数。
The PersonForm
can then create (either by new
or by using a PersonFactory
class) the Person
objects using some of the data from the array. 然后,
PersonForm
可以使用数组中的某些数据(通过new
或使用PersonFactory
类)创建Person
对象。
