Return values after &quot;Submit&quot;

Return values after "Submit"

asolell

Hi,

//////////////
Backgroud of what I want:
//////////////

I have a ContactUs.php that has a <form> with a UserName field. It is sent to a ContactUsHandler.php

If the $UserName=="", then return to ContactUs.php and Put RED Msg indicating empty string, please enter data.

//////////
Where I'm stuck:
/////////

Ok.. The info has made it to the Handler page.
if($UserName=="")
{

      How do I do a redirect to the calling page with a flag?
      (By flag I mean,.. passing a field called "MissingName"
       that has a value of "YES" and when I get back to the 
       calling page ContactUs.php, it will be evaluated,
       and display the "enter name").

}
else
{
normal processing of the data.
}

Thanks,

-Alon

you can use a header

<?
header(Location:ContactUs.php?MissingName=yes)

page code here

?>

thats at the top of contacyushandler.php

<?
if(MissingName==yes){
echo "MESSAGE";
}

contactus page code

sumot like that anyhow

Slight problem with that:

The ContactUs.php is not the only one calling the Handler page.
I have a 'product' page which at the bottom,..a user can enter his info and the same handler will process it.

The product page is Product.php?$Id so now I have 2 question marks.. is that possible?

Thanks,

yea

add a hidden form field with the values of

<input type="hidden" name="id" value="$id">
and on the page it sent to put this

if($username == ""){
header (Location:Product.php?id=$id&&Missingname=yes)
}

alter the code to suit your needs

I tried all sorts of 'combos' just to make it kick! BUT, with no luck.

Lets look at the simpliest form option. No '?' options.

A simple sent to a handler and 'auto' return back with
a 'flag' to either display a msg or not.
When I try to enter that code, I get headers were sent errors.

The sender File extract:

<table width="475">
<tr>
<td dir="rtl" width="304">A

<?php

  if ($MissingName == "YES")
  {
           echo "MISSING NAME";
  }

Handler file:

if($UserName == ""){
header (Location😛roduct.php?$MissingName=yes)
}

?>
<html>
<head>
<title>MyTitleHere</title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1255">
</head>

/* WHERE DO I PUT THIS LINE AT??

echo "<input type=\"hidden\" name=\"MissingName\" value=\"YES\">";
*/

<?php

Consider the following:

Sender file: ContactUs.php
<?php

if ($MissingName == "YES")
{
echo "MISSING NAME";
}
?>

<input type="text" size="35" maxlength="256" name="UserName" value=""></font></td>
<input type="hidden" name="sender_id" value="1">";

Sender file: Product.php
<?php

if ($MissingName == "YES")
{
echo "MISSING NAME";
}
?>

<input type="text" size="35" maxlength="256" name="UserName" value=""></font></td>
<input type="hidden" name="sender_id" value="2">";

Handler file:

if($UserName == "")
{
switch($sender_id)
{
case 1:
header (Location:ContactUs.php?$MissingName=yes);
break;
case 2:
header (Location😛roduct.php?$MissingName=yes);
break;
}
}

?>
<html>
<head>
<title>MyTitleHere</title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1255">
</head>

/* WHERE DO I PUT THIS LINE AT??

//echo "<input type=\"hidden\" name=\"MissingName\" value=\"YES\">";

// NOWHERE HERE!
*/

You could also user the $HTTP_REFERER variable in the handler script
to return back to the script the request came in the first place!
Some like the following:

Sender file: ContactUs.php
<?php

if ($MissingName == "YES")
{
echo "MISSING NAME";
}
?>

Sender file: Product.php
<?php

if ($MissingName == "YES")
{
echo "MISSING NAME";
}
?>

Handler file:

if($UserName == "")
{
header (Location:$HTTP_REFERER?$MissingName=yes);
}

?>
<html>
<head>
<title>MyTitleHere</title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1255">
</head>

metin

Here are some ready to test scripts:

Handler file (filename: handler.php):

<?php
if(isset($UserName) && $UserName== "") 
	{ 
	header ("Location: $HTTP_REFERER?MissingName=YES"); 
	} 
?>

Create as many file as you want with the following code and different names!
The handler file will always return the file that called it!

<?php
if (isset($MissingName) && $MissingName == "YES") 
	{
	echo "MISSING NAME <BR>\n"; 
	}

echo "<A HREF=\"handler.php?UserName=\">Check it?</A>";
?>

Thank you!

It worked!

And that is the most efficient one (with the referrer call)!
(funny,.. I just learned to use the referer code a day ago
and didn't think of it.. 😉

You are the best!

Thanks again.

// HANDLER CODE **

<?php
if(isset($UserName) && $UserName== "")
{
header ("Location: $HTTP_REFERER?MissingName=YES");
}
?>

// SENDER TO HANDLER CODE **
//That piece of code along with the

<?php
if ($MissingName == "YES")
{
echo "MISSING NAME";
}
?>

Just as a note,.. this code needs 'cleanup' procedures.. why???
cause when I user is ignoring the warning, and hits submit again.. this time the url he sends is:

ContactUs.php?MissingEmail=YES?MissingEmail=YES

and everytime you hit submit again.. it adds another.
This I think should be easy, I'll find the start position of the
word Missing and substr ($url,1,($positing-1)) and use
that as the referring URL.

Thanks again for your help.

The code I gave was not intended to be used directly -
it was just a demonstration!
Of course you have to clean up and check things, before using them!
F. ex. check out the "parse_url"-function to extract the different parts of an url:
http://www.php.net/manual/en/function.parse-url.php

Good luck!
