What is a .vc6 filetype? I bet you have a security setting in the
browser that doesn't allow opening that filetype on click... but you are
able to force the issue with direct input... but then again, I could
just be all wet behind the ears.

You seemed to miss the point Stephen was suggesting, to use your
template syntax:

   <input name="items[{number}]" size=60 class="formdata" value="{item}">

Then in your php code:

  $item = $_POST['items'];
  foreach($items as $i => $value) {
    echo "$i: $value<br>";
  }

I believe the difference between using =& and = is that the former passes
the value by reference, though I've never been clear about the benefits of
using one over the other when it comes to PEAR:DB (the PEAR:DB documentation
uses =& extensively, so presumably it is the better method).

"not able to do that" - what happens? What error messages do you get? Or
does nothing happen?

What is the scope of $image? Have you recognized it as a global within the
function, and declared it external to the function?

Have you deconstructed randomImage and built it up incrementally within
function.php?

Could it be that if you try and include it in functions.php there is output
somewhere sent to the browser before the header() and session_start()
functions are called?

Finally, what's wrong with calling it as you do at present? Flash
programmers are forced into that model for every class they create. It must
be an independent .as file, with the same name as the function, and contain
code only for properties and methods of that function.

Hi MARG,

It will be better if you can provide the code here and what error you are
getting.

BTW header function is the key here.

Hi,

I have this form:
http://www.tuxdoit.com/newsletter.php

If you care to check it, you'll see that
http://www.tuxdoit.com/formsResult.php

never returns the function value:

formsResult.php:
-------------------------------------
<?php
  include('functions.php');
  ini_set("display_errors","On");

  $email = $_REQUEST['email'];

  $emailResult = isEmailOk($email);

  print($emailResult);

  if ($emailResult == 1)
   print('Email Ok');
  else
   print('Email is not Ok');

?>
--------------------------------

functions.php:
--------------------------------
<?php

function isEmailOk($email) {
print($email);
 if (!eregi
("^([-!#\$%&'*+./0-9=?A-Z^_`a-z{|}~^?])+([-!#\$%&'*+/0-9=?A-Z^_`a-z{|}~^?]+\\.)+[a-zA-Z]{2,6}\$",
$email))
  return 1;

 } // is EmailOk

?>
-------------------------------

Why is that happening ?

Any help would be apreciated.

I would wager because there's a ! operator preceding the ereg() call.
Also you have very dirty code, your isEmailOk() function doesn't return
a value in the case that the if expression fails, it assumes PHP will
return something useful (PHP returns null, but relying on that is asking
for trouble, and I doubt you knew so in the first place).

Cheers,
Rob.

Hi folks,
  
 I'm a ColdFusion developer, but I'm branching out into PHP because alot of my smaller clients don't want to pay for CF.
  
  Anyway, a bit of background:
  
  I've got a page that does a search on one of my tables. I'm using Justin Vincent's ezSQL (http://php.justinvincent.com) to fetch the result set into an object that can be referenced nicely. Here's what his example code looks like:
  
          // Select multiple records from the database and print them out..
          $users = $db->get_results("SELECT name, email FROM users");
          foreach ( $users as $user ){
                       // Access data using object syntax
                      echo $user->name;
                      echo $user->email;
          }
  
  So far so good. So I've got an iframe on the page which (I hope) will eventually display the results of the search. The user will then click on the search result for which they want to view the details, and the information from that row will be populated inside the main page (the one that houses the iframe).
  
  Hope that makes sense.
  
  Okay, so my trouble is that I don't know how to enable the page inside the iframe to have access to the result object created by Justin Vincent's nifty little class. In CF I can just say:
  
     session.oResults = queryname
  
  CF automatically returns any query as an object with the name of the query as the object name (i.e. queryname.MyIdField, or queryname.EmployeeNumber, etc.) Using a line like the one above (assigning the query object to a session variable) all of my subsequent requests would have access to that result set simply by using the object.
  
  I'm *sure* there's a way to do this in PHP. I'm just falling short of finding the answer. I've tried:
  
      $_SESSION["SearchResult"] = $db->get_results($query);
  
  But it doesn't seem to work. I may have some other problem using the object. I just re-read my error and it says:
  
  Fatal error: Call to a member function get_results() on a non-object in inventorymanager.php on line 93
  
  hmm... I sure would appreciate a little guidence here. Even if my problem is with the way I'm using the object, is the idea of assigning that object to the session scope the right way to do this or is there a better approach. To that end, I suppose I'm looking for an idea of the best practice.

Not sure if I can give a good answer, but try doing a var_dump on
$_SESSION["Search Result"] and see what you get. I suspect that it is
null. If that's the case then track down where it is getting assigned.
It should look something like $_SESSION["SearchResult"] = $users.

I've been working with php's socket library and I've run accross the
stream_socket_ library.
I'm wondering whether I should be using that library instead?

Is there anything that makes the stream_socket library superior to the
traditional socket library for writing
TCP/IP socket clients and servers?

Also, Is there any way to add the functionality of the
stream_socket_enable_crypto()
to a program written using traditional socket library (any available
classes or extensions that would help
add that functionality?).

thanks alot!
