[PHP5] OOP Problems

Drezard · December 28, 2007

Okay, I'm working with 4 main files in this problem. Very small amounts of code. Now, so far profiles.class.php is running a function (create) which requires a function (post) from another file forms.class.php which contains the class forms. Now, Im getting this error:

Fatal error: Call to a member function posted() on a non-object in C:\xampp\htdocs\client\extensions\profiles.class.php on line 11

profiles.class.php:

<?php

require_once('extensions/forms.class.php');

$forms = new forms;

class profiles {

function create() {

	$result = $forms->post();

	if ($result == false) {

		echo "Complete the fields marked with <span class='main-first'>*</span><span class='content'>";
		echo "<table width='50%' border='0'>";
		echo "<form method='post'>";
		echo "<tr>";
		echo "<td width='25%> Name: </td> <td> <input type='text' name='name'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Email: </td> <td> <input type='text' name='email'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Address: </td> <td> <input type='text' name='address'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Postcode: </td> <td> <input type='text' name='postcode'> </td>";

		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%'> <input type='submit' name='submit'> </td> <td> </td>"; 
		echo "</tr>";
		echo "</form>";
		echo "</table>";

	}

}

}

?>

forms.class.php:

<?php

class forms {

function post() {

	if (isset($_POST['submit'])) {

		return true;

	}

	else {

		return false;

	}

}

function check($value) {

	if (trim($value) == '') {

		return false;

	}

	else {

		return true;

	}

}

}

The object $forms does not exist within the class profiles. You need to define it within the class itself, no good defining it outside because it is out of scope. eg;

<?php

  class forms{}

  class profile {
    private $forms;
    function __construct() {
      $this->forms = new forms; // now the forms object can be accessed within the profile class using $this->forms.
    }
  }

?>

Same error, Different line. New code for profiles.class.php:

<?php

require_once('extensions/forms.class.php');

class profiles {

private $forms;

function __construct() {
      
	$this->forms = new forms; 
    
}

function create() {

	$result = $forms->post();

	if ($result == false) {

		echo "Complete the fields marked with <span class='main-first'>*</span><span class='content'>";
		echo "<table width='50%' border='0'>";
		echo "<form method='post'>";
		echo "<tr>";
		echo "<td width='25%> Name: </td> <td> <input type='text' name='name'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Email: </td> <td> <input type='text' name='email'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Address: </td> <td> <input type='text' name='address'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Postcode: </td> <td> <input type='text' name='postcode'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Suburb: </td> <td> <input type='text' name='suburb'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Phone Number: </td> <td> <input type='text' name='phone'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%> Mobile: </td> <td> <input type='text' name='mobile'> </td>"; 
		echo "</tr>";
		echo "<tr>";
		echo "<td width='25%'> <input type='submit' name='submit'> </td> <td> </td>"; 
		echo "</tr>";
		echo "</form>";
		echo "</table>";

	}

}

}

?>

use

$this->forms

, not

$forms

within the create method.

You obviously haven't got your basics covered. Try a OOP tutorial.
