Calling a class from within a class

[jimmyt1988]

Hi all,

 

I have two classes. Registration and Connection.

 

Inside a registration.php I include my header.php, which then includes my connection.php...

 

So all the classes should be declared when the page is loaded.

 

This is my code:

 

registration.php:

<?php include ('assets/header.php'); ?> 
        
    <?php
        class registration{                    
            public $fields = array("username", "email", "password");
            public $data = array();
            public $table = "users";
            public $dateTime = "";
            public $datePos = 0;
            public $dateEntryName = "date";
            
            function timeStamp(){
                return($this->dateTime = date("Y-m-d H:i:s"));
            }
            
            function insertRow($data, $table){      
                    
                    foreach($this->fields as $key => $value){
                        mysql_query("INSERT INTO graphs ($this->fields)
                        VALUES ('$data[$key]')");
                    }
                    
                    mysql_close($connection->connect);
            }
            
            function validateFields(){
            
                $connection = new connection(); 
                $connection->connect();
                        
                foreach($this->fields as $key => $value){
                    array_push($this->data, $_POST[$this->fields[$key]]);
                }
                $this->dateTime = $this->timeStamp();
                array_unshift($this->data, $this->dateTime);                
                array_unshift($this->fields, $this->dateEntryName);   
                
                foreach($this->data as $value){
                    echo "$value";
                }
                
                $this->insertRow($this->data, $this->table);
            }
        }
        
        $registration = new registration();
        $registration->validateFields();
    ?>

<?php include ('assets/footer.php'); ?>

 

At this point I cannot find my connection class defined on another included/included page.

 

                $connection = new connection(); 
                $connection->connect;

 

config.php (included within header.php)

<?
    class connection{ 
        public $dbname = '**';   
        public $dbHost = '**';
        public $dbUser = '**';
        public $dbPass = '**';
        public $connect;
        
        function connect(){
            $this->connect = mysql_connect($this->dbHost, $this->dbUser, $this->dbPass) or die ('Error connecting to mysql');
            mysql_select_db($this->dbname, $this->connect);
        }
    }
?>

 

Any ideas how to call it properly?

[Anti-Moronic]

From what I can tell you are calling it properly. It's hard to tell what the problem is without first seeing the other files involved and also what, if any, errors you are receiving.

[trq]

class $connection{ 

 

Should give you an error.

 

class connection {

 

is valid.

[jimmyt1988]

Oh god its late, sorry.. Funny enough, it hasn't solved the problem ... can u see any more pathetic errors?

 

anti mormic, ive updated my original post to help.

Your need to use full php opening tags <?php in all your code.

 

Edit: Also, the instance of your connection class is only available inside the validateFields() function, unless you assign that to an object of your registration class.

Updated:

 

registration-post.php:

<?php include ('assets/header.php'); ?> 
        
    <?php
        class registration{                    
            public $fields = array("username", "email", "password");
            public $data = array();
            public $table = "users";
            public $dateTime = "";
            public $datePos = 0;
            public $dateEntryName = "date";
            private $handle;
            
            function timeStamp(){
                return($this->dateTime = date("Y-m-d H:i:s"));
            }
            
            function insertRow($data, $table){      
                    
                    foreach($this->fields as $key => $value){
                        mysql_query("INSERT INTO graphs ($this->fields)
                        VALUES ('$data[$key]')");
                    }
                    
                    mysql_close($connection->connectData);
            }
            
            function validateFields(){
            
                //Line 29
                $this->handle = new connection(); 
                $connection->connect();
                        
                foreach($this->fields as $key => $value){
                    array_push($this->data, $_POST[$this->fields[$key]]);
                }
                $this->dateTime = $this->timeStamp();
                array_unshift($this->data, $this->dateTime);                
                array_unshift($this->fields, $this->dateEntryName);   
                
                foreach($this->data as $value){
                    echo "$value";
                }
                
                $this->insertRow($this->data, $this->table);
            }
        }
        
        $registration = new registration();
        $registration->validateFields();
    ?>

<?php include ('assets/footer.php'); ?>

 

 

config.php:

<?php
    class connection{ 
        public $dbname = '**';   
        public $dbHost = '**';
        public $dbUser = '**';
        public $dbPass = '**';
        public $connectData;
        
        function connect(){
            $this->connectData = mysql_connect($this->dbHost, $this->dbUser, $this->dbPass) or die ('Error connecting to mysql');
            mysql_select_db($this->dbname, $this->connectData);
        }
    }
?>

 

ERROR: Fatal error: Class 'connection' not found in \www\registration-post.php on line 29

I see. registration-post.php must include/require the file containing the class definition (config.php). we still haven't seen header.php yet...

[jimmyt1988]

Omg, thankyou for asking that question. bad pathing. *hits head against table* thanks. ill sort the pathing out then come back and tell if its all ok.

[jimmyt1988]

www/registration-post.php

www/config.php

www/assets/header.php

 

The problem is in header.php.

 

I am including the config.php with the pathing like this:

 

<?php include('../config.php'); ?>

 

But that isnt finding the config file.. even though its going back a directory (out of assets) and into the root (www) ? can you not do that with include function?

[BlueSkyIS]

i prefer full paths to includes:

 

<?php include($_SERVER['DOCUMENT_ROOT'].'/config.php'); ?>

[jimmyt1988]

AND THEN IT WORKS. lol.. Goodness, i wish i knew what i did wrong. maybe my apache config was intefering with somerthing. the complete root now functions perfectly. THANKSSSSSS
