I'm building a class to save data to the Database, but I'm without ideas on how to deal with this...
I have my project folders like this:
+Lib
+Models
+Uddt
-person.php
-uris.php
Main_class.php
Example_usage.php
The folder "Models" have the uris.php file that have methods to add and retrive information from the database tables.
The folder "Models\Uddt" have the User Defined Data Types that I have defined, for example, the person.php looks like this:
class Person {
static $id_category = '2';
public $uri;
public $name;
public $age;
public $sex;
public $address;
public $country;
public function _Name() {
// Connect the property name to the db name
$db_name = 'name_in_db';
// Some more code
}
public function _Age() {
// Connect the property name to the db name
$db_name = 'age_in_db';
// Some more code
}
public function save() {
// do things to save the data to the database
}
}
The database tables looks like this:
Table(uris_details)
uri (PK FK)
id_category (PK FK)
id_data_type (PK FK)
n_text
Table(uris)
uri (PK)
id_uri_state (FK)
To insert the data to the database I want to use an object, just like this:
// Instantiate the object
$p = new Person;
// Add the values to the object
$p->uri = 'http://www.fdsddd.com/gfd1';
$p->name = 'John';
$p->age = '27';
$p->sex = 'Male';
$p->address = '10 Street';
$p->country = 'USA';
// Save the data to the database
$p->save();
The INSERTs will look like this:
INSERT INTO uris (uri, id_uri_state) VALUES ('http://www.fdsddd.com/gfd1', 'active');
INSERT INTO uris_details (uri, id_category, id_data_type, n_text) VALUES ('http://www.fdsddd.com/gfd1', '2', 'name_in_db', 'John');
INSERT INTO uris_details (uri, id_category, id_data_type, n_text) VALUES ('http://www.fdsddd.com/gfd1', '2', 'age_in_db', '27');
INSERT INTO uris_details (uri, id_category, id_data_type, n_text) VALUES ('http://www.fdsddd.com/gfd1', '2', 'sex_in_db', 'Male');
INSERT INTO uris_details (uri, id_category, id_data_type, n_text) VALUES ('http://www.fdsddd.com/gfd1', '2', 'address_in_db', '10 Street');
INSERT INTO uris_details (uri, id_category, id_data_type, n_text) VALUES ('http://www.fdsddd.com/gfd1', '2', 'country_in_db', 'USA');
My question:
How can I structure the "save()" method in the "Person" Class to save the data to the Database, any ideas? I must to do a transaction? I'm using PostgreSQL, shoul be better to create a PlPgSQL function to deal with the transaction?
Give me some clues.
Best Regards,
