list items --> textarea help...

ENC

I'm stuck...

I have a simple xhtml (mobile) form that contains a dropdown list of items and a textarea.

In use the user selects an item off the list, clicks an 'insert' button and it get added to the textarea. In my application the dropdown list is used to speed up data entry for Cell phone users - the idea is to use the dropdown list to drops 'commands' in to the textarea- so the user does not have to enter the command(s) AND the data required by the command(s)... I will have a list of about 30 commands, each requires additional data to be entered:

SHOW_MESSAGE hi world

SHOW_MESSAGE is inserted from the dropdown, the hi world part is the data entered by the user...

First Questions:
The xhtml suff is done, but the PHP scrip is giving be trouble:

<select name="itemlist">
<option value="1">SHOW_MESSAGE</option>
<option value="2">SEND_MESSAGE</option>
</select>

<?
if ($POST['submit'])
{
echo '<input type="hidden" name="already_selected[]" value="'.$POST[itemlist].'">';
}

echo <textarea name="mycmds">;

if (is_array($POST['already_selected']))
{
foreach ($POST['already_selected'] as $key => $value)
{
echo $value;
}
}
echo $_POST['mycmds'];

echo '</textarea>';
?>

This does't seem to work - What did I miss?

Second Questions:
Ideally I would like to embed this in the xhtml code - is this possible, or does it always have to be a seperate PHP file?

Thanks for any help!

All this should be copied to one ''pagename.php"
You can name it anything,
Because 'action=PHP_SELF' will load this page again, at Submit..

This is the standard.
We put PHP CODE, with variable testing, at beginning of a form page
and
HTML part with the <FORM ... at the end of page.

<?php
if ($_POST['submit']=='insert') {
   if ($_POST['itemlist']){
      //add new insert
      $select = $_POST['itemlist'];
      $text = $_POST['mycmds'].$select."\n";
   }
   echo 'Was inserted';
}

elseif ($_POST['submit']=='finished') {
   // This is end
   echo "Okay. Finished<br>";
   echo "Result:<br>";
   echo $_POST['mycmds'];
   exit;
}

else{
// This is start
   $text='';
   echo 'Please insert commands';
}
?>

<!-- This is the HTML part -->
<form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<select name="itemlist">
<option value="have a drink of: ">HAVE_DRINK</option> 
<option value="show me: what???">SHOW_ME</option> 
<option value="goto sleep at: ">GOTO_SLEEP</option>
<option value="send me some: ">SEND_ME</option> 
</select> 
<br>
<input type="submit" name="submit" value="insert">
<br><br>
<textarea rows="10" cols="30" name="mycmds"><?php echo $text ?></textarea>
<br>
<input type="submit" name="submit" value="finished">
</form>

This could be a start.
I did not get it all perfect. But I am not an expert, yet.
I have tested it.
Works!

Halojoy -

A bit more help if you could:

What I'm writing is a protal for cel phone users so it would seem I would need to include the appro. XHTML header:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN"
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html>
<head>
<title>AgentSpeak Portal Version 1</title>
</head>
<body>

Also - I have a text field that needs to keep its data after each update (caused by the insertion of data from the dropdown)...

Any thoughts - or am I cooked...

Regards,

Ian C
