php with OOPS practical example?
i have been programming in php for a while and i do know all the concepts of OOPS as well.... i lack clarity on how i can bring these two together. below is an example of my code.
This is really old code so i donot use tables any more but rather use CSS div (without absolute positioning to render to all resolutions) so i dont have any issues with the CSS.
Code:
<?php include_once ('includes/session.php') ?>
<?php
include_once ('includes/mysql.php');
include ('includes/edit_reportids.php');
$obj=new db();
$obj->connect();
$disp="";
//module to retrieve all the sub categories for a given category to add new inventory
if((!isset($_GET['id'])))
{
$disp.= "Select Category<select name=\"inventory\" onChange=\"DisplayContent(this.value);\" >
<option value=\"0\" >Select Category</option>
<option value=\"sample_request\" >Sample Request</option>
<option value=\"sample_received\">Sample Received</option>
<option value=\"sample_correction\" >Sample Correction</option>
<option value=\"final_details\">Final Details</option>
<option value=\"orders\" >Orders</option>
<option value=\"confirmation_samples\">Confirmation Samples</option>
</select>";
}
else
{
$disp.="<table cellpadding=5px cellspacing=0 border=1><tr><td colspan=4><table cellpadding=5><tr><td>";
}
?>
<?php
include_once ('head.php');
if((isset($_GET['id'])))
{
$id_val=$_GET['id'];
//CODE TO DISPLAY ALL THE STYLENAME-COLOR MATCHES ON TOP OF THE EDIT FRAME
for($i=0;$i<$sidsize;$i++)
{
$disp.=" | <a href=\"edit_report.php?id=$id_val&&sid=$sidlist[$i]\">".$stylelist[$i]."-".$colorlist[$i]."</a> | ";
if(($i+1)%10 == 0)
$disp.="</td></tr><tr><td>";
}
$disp.="</table>";
//MAIN EDIT FRAME SWITCH USED TO DETERMINE WHICH TABLE TO MANIPULATE OR ADD
if(isset($_GET['sid']) && isset($_GET['id']))
{
switch($id_val)
{
//CASE SAMPLE REQUEST
case "sample_request" :
$tbname=$_GET['id'];
$sid=$_GET['sid'];

Well when i complex projects it gets really all messed up and goes all over the place. i know i could render each functionality in a class and have functions in it but i still dont understand how would i spit out the htmls. Would it be returned from the function in a variable? basically if i could get some pointers to links or books which actually take a real project (small scale) and show how its done in OOP it would clear my doubts. all the existing books explain on all the features and properties of OOPS (theory) which i know.
thanks.
