[Problems getting started with OO PHP]

Hello All,

 

I been fighting with this code all day yesterday and for the life of me it is not working...

 

Anyone provide any help please with caffeine ontop.

[[SOLVED] Determining cc type based on first digit - code not working]

try something like this...

 

 

<?php

 

//test number

$cc_num = "123312312";

 

$number = "$cc_num";

$last_four = substr($number, -4);

$first_one = substr($number, 1);

if($first_one=3){$cc_type = "American Express";}

elseif($first_one==4){$cc_type = "Visa";}

elseif($first_one==5){$cc_type = "MasterCard";}

elseif($first_one==6){$cc_type = "Discover";}

else {$cc_type = "Unknown";}

 

//bla data

$authxyz = "234";

$amount = "123.44";

 

Print "

[change to new page]

here a old script i wrote about year ago.

 

<script language="JavaScript">

function SESSION_TIMEOUT()

{

var t=setTimeout("KICK()",32400000);

}

 

function KICK()

{

window.location = "index.php";

}

 

</script>

 

 

 

32400000 is milliseconds i think..

 

 

i also used my own custom session control and a time stamp the sessions inside my database. if they where not stamped within the time period the session would be removed from the db and then they javascript would fire locally to make sure they know they been kicked.

 

I stamped the session each time they browsed to another page and used this script of more of a inactivity kick script to kick the users off if they left there pc running all day and forgot about it and went home.

[variable isn't getting passed along.]

I don't think you should output to the browser with any type of print statement directly from the object.

 

I think you should returned the result to your application then have your application output to browser

[Whats O.O.P?]

Object oriented coding is is different form of thinking.

 

think of it like linking many functions together and each function can do its own thing but knows what all they other functions do..

 

now multiply this by 100 and you now have object oriented programming.. you can duplicate your entire project and override one function etc. 

 

instead of calling the same function, you can duplicate it and call it as its own object with its own properties etc.

 

[Problems getting started with OO PHP]

Hello All

 

I am new to the forum, i just joined.. looking forward to a good place to meet other pro php developers.

 

My OO knowldge is very limited, I been doing mostly php procedural coding.  I am starting my next project here at work and I trying to do this one with a CLASS Objects to see how it all works out.

 

 

I am getting some errors, and Its prob because I dont know OO and PHP.

 

I read a bunch of documents on it, however there are still little questions I cant seem to find exact answers for.

 

Below is the code I wrote so far to connect to the database.

 

<?php

//The DB_OBJECT simple creates the connection to the database

//this object must be called first.

 

class DB_OBJECT {

// pirvate user object data

var $db_username;        // username for the db

var $db_password;        // password for the db

var $db_server_name;      // the db server_name

var $db_db_name;          // the db database name

 

var $db_returned_status;  //true if connection successfull, if false returns error.

var $db_primary_object;  // used to store database connection object

 

    function connect($db_username,$db_password,$db_server_name,$db_db_name)

    {

 

        if (!this->$db_primary_object)

        {

        //create connection object.

        this->$db_primary_object = mysql_connect($db_server_name,$username,$password);

 

                                if (!this->$db_primary_object)

                                {

                                this->$db_returned_status==mysql_error();

                                }

                                else

                                {

                                this->$db_returned_status=true;

                                mysql_select_db($db_db_name,$db_primary_object);

                                }

        }

 

    return $this->$db_returned_status;

    }

 

}

 

?>

 

 

But I keep getting a error, and I think it has something to do with the this->$db_primary_object part of the code.

 

maybe some hidden rules with php and OO i am not getting ?

 

Parse error: parse error, unexpected T_OBJECT_OPERATOR in \htdocs\sales\include\db.php on line 21

 

 

here is the basic code i am using to test the object.

 

<?php

include ($_SERVER['DOCUMENT_ROOT'].'/sales/include/db.php');  // DB Connection object

 

// connect to database using custom db object

$database_obj=new DB_OBJECT("username","password","localhost","call_center");

 

?>
