$to_date
  1. Open a new \'Simple Page\' template.


  2. Add this code near the top of PHP source-code: 
                          global $from_date, $to_date;
                      if (isset($_REQUEST[\'date\']))
                      {
	                    $from_date = $_REQUEST[\'date\'];	
                      }
  3. Add this task to the PHP source-code: 
                          if ($pf_task == \'convert_date\')
                        convert_date();
  4. Add this function to the PHP source-code: 
                          function convert_date()
                      {
                      	// Make all global variables available here
                      	foreach($GLOBALS as $arraykey=>$arrayvalue) 
                      	{
                      		global $$arraykey;
                      	}
                      
                      	if( strtotime($from_date) ){
                      		$to_date = strftime("%Y/%m/%d", strtotime($from_date));
                      	}
                      	else{
                      		$to_date = "Not a valid date format";
                      	}
                      	wrtseg(\'MainSeg\');	
                      }
  5. Add this html to the main segment: 
                        
                        <form name="val_date" action="$pf_scriptname" method="POST">
                          <input type="hidden" name="task" value="convert_date">
                          <table>
                            <tr>
                              <td>Enter date:</td>
                              <td><input type="text" name="date" value="" size="35"></td>
                              <td><input type="submit" value="Submit "></td>
                            </tr>
                          </table>
                        </form> 
                        
                        <div style="color:red; margin-left: 100px; text-style:bold;"><b>$to_date</b></div>
