passing var page to page

cindy

I am a new user in PHP programming. I am having problems passing variable(s) from one page to another using html fill-in Forms. Could someone help me on this

###----- below is my input part of the program

<?include("odbcconnection.phtml"); ?>

<?
global $PINA;
if ($RedirectAction=="Open")
{
$QueryID = "Select * from usertable Where userid = '$userid' and password = '$userpassword'";
if (!($Result = odbc_do($odbc_db, $QueryID)))
die ("Error in SQL");

     // use this for odbc connection, other database use the block below	

	 $cols = odbc_num_fields($Result);		  
     while (odbc_fetch_row($Result)) 
	 {
	   for ($a =1; $a <= $cols; $a++)
	   {
	 //    $checking = 1;
	     $data = odbc_result($Result, $a);
	   }
	 }
	 if ($data == "")
	 {
	   $Cancel = 1;
	 }
	 $PINA = $userid;

}
?>

<?
if (($RedirectWhere<>"")&&($Cancel==""))
{
echo "<META HTTP-EQUIV='Refresh' CONTENT='0;URL=".$RedirectWhere."'>";
exit;
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<head>
<title>Untitled</title>
</head>

<body bottommargin=0 topmargin=0>
<form method="POST" action="open.phtml">
<input type="hidden" name="RedirectWhere" value="<?echo $RedirectWhere?>">
<input type="hidden" name="RedirectAction" value="<?echo $RedirectAction?>">

<TABLE WIDTH="600" BORDER="0" ALIGN="center">
<TR>
<td align="center"> Login Form
</td>
</tr>
<tr>
<td align="center"><input TYPE="text" NAME="userid" SIZE="8"> <BR>
<input TYPE="password" NAME="userpassword" SIZE="8">
<?
if ($Cancel==1)
echo "<BR><tr><td ALIGN='center'><font color='red' face='verdana' size='2'> Please try again </font></td></tr>";

?>

</td>
</tr>
<tr>
<td align="center"><input type="submit" name="Open" value="Open" Onclick="Redirect('second.phtml', 'Open')">   <input type="submit" name="Back" value="Back" OnClick="Redirect('open.phtml', 'Back')"></td>
</tr>
</table>

</form>
</body>

<?include("odbcloseconn.phtml")?>

end here

second page is the response from the above pprogram (FORM)

Start here ####

<?
include("odbcconnection.phtml");
if (!$PINA)
{
echo "<META HTTP-EQUIV='Refresh' CONTENT='0;URL=open.phtml'>";
exit;
}

$query = "Select * from usertable Where userid = '$userid' and password = '$userpassword'";
print $PINA;

end

Thank you very much

an easy way is to pass variables in a query string (if its a form use GET)

you might have to 'urlencode($var)' if it has spaces or other nonletter characters.

this method is good for testing because you can see what the variables actually are in the status window of the browser......

I can pass them, but how do I retrieve them on the following page ?? I already tried
$HTTP_GET_VARS, but it doesn't work well.

Any ideas appreciated ...

How do you know you have passed them if you cant retrieve them? - You have to make use of them on the next page by calling the variable - print, echo or assign it another value and print that...

here is some working code for two pages that you should keep as a reference

"11.php":

<?php
print "<form action=12.php method=GET>
<input type=text name=word>
<input type=submit>";

print "<p>different example:";
$var="what ever you passed to it";
print "<p>With a hrefs:
<a href=\"12.php?something=$var\">Pass the variable in a link by appending a query string</a>";

"12.php":

<?php
print "$word<p>$something";
?>
