Hello all,

Iīve got some problems with the syntax (on itself the smarty language is very easy). Please take a little bit care for my knowladge with the following used programming-languages. Iīm in a learning process with websolutions.

Iīve got this special problem:
It deals with a function wich refer from "update.php" to a file called "change.php" to do some action (set doit = 1 and refresh page "update.php").

Why post this problem in the smarty forum ?:
I just solved this in a rudimentary way without smarty but Iīm working with an extension wich not allow to make this function useful for this content and it works with smarty. A "<form>" in the refered "tpl"-file in this extension does already exist and this would impliment a "<form>" in a "<form>" that the following "solution" doesnīt work. Itīs a joomla extension. Hope Iīm right here, really need help.

The only way I can see is "<a href="change.php" onclick="if (confirm('doit?')) //dosomthing; return false;">"
Reason:
The file "change.php" has to change an sql-fieldvalue called 'doit' from 0(Standard on insert: null) to 1 with update by automatically select an existing subject by clicking a button/link.

1st steps of solution (Please donīt ask why first update and than delete - I think you will understand it shortly):
I tried it by using sql and php by a raw test(without using smarty). So far so good - the raw test was working (by using "<form>").
But I need a solution with using smarty(or not, itīs not nessessary) and without using form(or include a new input into the existing form - donīt know how).


Here is the code of the raw test if anybody would like to know (ordered by a logically way):

update.php
Code:

<?php
 session_start();
 $token = $_SESSION['token'];
 session_register('token');
 unset( $_SESSION['token'] );
?>
<!--<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">-->

<html>
 <head>
  <?php
   // Create a $string
   $_SESSION['token'] = $string;

     require_once('config.php'); // Connection
     $select_hid = "select * from persons where id = '100' and doit='1'";
     // I need a variable select 'id' by a specified automatically detected $id (it means not '100' but $id[one of them from 1 to end - Further validations already exist]).
     // id is a auto_increment primary key - How to realize "select * from persons where id = '$id'"?
     $meg_hid = mysql_query($select_hid) or die(mysql_error());
     $line_meg_hid = mysql_fetch_assoc($meg_hid);
     $this_line_meg_a = mysql_num_rows($meg_hid);
     mysql_free_result($meg_hid);
     $werdtfgj='0'; if ($select_hid==true) $werdtfgj='1'; // Iīm not sure why creating this line but I think it wonīt work if itīs not theire
     mysql_close($con);
     if ($this_line_meg_a=='1'){
       echo "<title>Updated</title>";
     }else{
       echo "<title>Update this</title>";
     }
  ?>
  <meta name="author" content="Dennis H.">

 </head>
 <body text="#000000" bgcolor="#FFFFFF" link="#FF0000" alink="#FF0000" vlink="#FF0000">

  <form id="doit" name="doit" method="post" action="change.php?str=<?php echo $string;?>">
   <?php
   if ($this_line_meg_a=='1'){
    echo "It works!!!";
   }else{
    include('action.php');
   }
  ?>
  <br />
  <?php echo $_POST['doit']; ?>
  <input type="hidden" name="token" id="token" value="<?php $string; ?>" />
  </form>

 </body>
</html>


action.php
Code:

// Itīs easier to include
   <a href="<?php echo $line_meg_a['megLink'];?>" onclick="if(confirm('Do it?')) javascript:document.doit.submit(); return false;"; />
    <input type="image" src="pic.png" alt="<?php echo $line_meg_a['megAlt'];?>" />
   </a>


change.php
Code:

<?php
  session_start();
?>
<html>
 <head>
  <?php

  function Page() {
   $page = 'http';
   if ($_SERVER["HTTPS"] == "on") {$page .= "s";
   }
   $pageURLstr .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
      $page .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
     } else {
      $page .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
   return $page;
  }
  require_once('config.php'); // Connection
  $tag = substr(Page(),-16, 16) ;
   if ($_SESSION['token']==$tag){
     $inv_a = "update persons set doit = '1' where id ='100'";
     $del = "delete persons where id ='100' and doit = '1'";

     $doit_a = mysql_query($inv_a);
     $doit_c = mysql_query($del); // It doesnīt delete the row, please tell me why???

     $select_a = "SELECT * FROM persons where id = '100' AND doit='0'";
     $meg_a = mysql_query($select_a) or die(mysql_error());

     $line_meg_a = mysql_fetch_assoc($meg_a);
     $this_line_meg_a = mysql_num_rows($meg_a);

     mysql_free_result($meg_a);
     mysql_close($con);

     echo '<table width="100%" height="100%"><tr valign="middle" align="center"><td valign="middle" align="center">';
     echo '<img width="17px" height="17px" src="pic.gif">';
     echo "The process will accepted.<br />- Please wait a moment -";
     echo '</td></tr></table>';
   }else{
     echo '<table width="100%" height="100%"><tr valign="middle" align="center"><td valign="middle" align="center">';
     echo '<img width="17px" height="17px" src="pic.gif">';
     echo '<br />';
     echo "Please do not enter another URL as automatically generated - Has not worked, try again!";
     echo '</td></tr></table>';
   }
  ?>
 <meta http-equiv="refresh" content="2 URL=update.php" >
 </head>
 <body bgcolor="gray">

 </body>
</html>


Again, the content works with a 'tpl'-smarty-content and I donīt know how to integrate this working test function on this way.
Also I dont know how to select a coulumn by a primary key - Does anyone could explain or give an example code? -Shame on me, I know.-
These are my questions and solution up to this point. Please give me some feedback. Maybe another idea to disolve it.

In the next step I explain the very specified problem. This was just a test (a warm up:) ), I hope itīs not to much...

Best regards,
DH
