[SOLVED] Trying to achieve this in OO

[depojones]

Hi genius,

 

I am processing a form on the same page using the procedural approach like this:

<?php
if(isset($_POST['submit']))
{
  if(trim($_POST['firstname']==""))
   {
     echo 'firstname is missing';
    }
   else{
     echo 'firstname is fine';
   }
   
}
?>

 

How do I apply such logic using OOP approach.

 

Thanks in advance

This is not a case for OOP. However you could create a validation object. You would have to assign the input and the test you wish to run.

 

i.e.

 

class validate {
  private $data;  
  public $errors;

  public function __construct($data) {
    $this->data = $data;
    $this->errors = array();
    $this->processData();
  }

  private function processData() {
     // loop through data and run each test
  }

  private function testNumeric() {

  }

  private function testEmpty() {

  }
}

$data = array(array($_POST['firstname'],'empty'),
                   array($_POST['age'],'numeric'));
$validation = new validate($data);
if(count($validation->errors)) {
  // display errors
}

Bit too small of an example to make a class out?

<?php
class Mon()
{
   /**
   * @param String $str
   * @return String
   */
    function missingOrNot( $str )
    {
        if( trim( $str ) == '' )
        {
             return $str.' is missing';
        }
        else
        {
             return $str.' is fine';
        }
    }
}

if(isset($_POST['submit']))
{
    $monInstance = new Mon();
    echo $Mon->missingOrNot( $_POST['firstname'] );
}
?>

@ All

 

The example was just an understanding of what am trying to do. I have a form of over 30 input and I will be testing all for errors.

 

Lastly, can I include my class file at the top of the form and if Yes, how is the whole process like.

 

Am new to PHP, please bear with me

I dont know if I need to provide more clue. I can perform this task comfortably using the procedural approach. I still don't get the OO method.

Then you should read in the manual for examples and explanations of how to code in OOP: PHP OOP
