[RESOLVED] Variables not included when form posts to SELF

kirax2

Here is a script I have been working on:

<html><body>
<font face="arial">
<title>Univelt Data</title>
<?php

if (isset($_POST['submit']))
{
	if ($submit=="Test")
	{ include "IncludeVariables.php";
	include "IncludeHiddenForm.php";
	include "IncludeHTML.php"; 
}	
	elseif ($submit=="Insert into Database")
	{ include "IncludeVariables.php";
	include "IncludeHiddenForm.php";
	include "IncludeInsert.php"; }
	else
	{ echo "Submit button value not properly defined."; }
}
else
{ include "IncludeForm.php"; }

?>
<form method="post" action="<?php echo $_SERVER[’SCRIPT_NAME’] ?>">

<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Test">
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Insert into Database">

<p>

The following files are in actuality more complicated; I have cut them down.

IncludeVariables.php:

$title = $_POST['title'];

IncludeHiddenForm.php:

<input type="hidden" name="title" value="<?php echo $title;?>">

IncludeHTML.php:

<?php echo $title; ?>

IncludeInsert.php:

   $host = 'localhost';
   $user = 'username';
   $pw = 'pass';
   $db = 'database';
   $connect = mysql_connect($host, $user, $pw)
              or die ("Could not connect.");
   mysql_select_db($db);
   $table1 = 'table;

$prod_statement = "INSERT INTO $table1 (title) VALUES('$title')"; echo "Item add";

if(mysql_query($prod_statement, $connect)){
  print " successful.<br/>";
   }
   else { print " failed.<br/>"; }

IncludeForm.php:

What is this book's title?<br> 
<input type="text" size="100" name="title" maxlength = "255">

The basic idea is that the form is displayed, information entered, the user pushes "Test" which will validate the form and display the data as it will be formatted for the website. If all goes well, the user can then submit the data to the database.

The issue is that when I have the form submit to itself, the values of the variables do not get included. It works if I submit the values from outside, for example, if I have a "dataform.html" which submits the values to this script, they come through perfectly initially. I've looked all over and tried several variations of self reference, including $SERVER[’PHP_SELF’], $SERVER[’SCRIPT_NAME’], and even simply using the actual name of the script. I also included the hidden form to try to retain the values; but no dice. When I press "Test", I get a blank page, and when I look at the source, I can see that the values are non-existent in the hidden form (i.e. <input type="hidden" name="title" value="">). I've looked all over for a solution to this, but I can't figure out what I'm doing wrong. I'd be grateful for any help you can give me.

None of the input has been sanitized of validated yet; I'm just trying to make it work first.

Thanks,

In the very first code snippet, where is $submit ever defined?

Thank you for your reply.

That's a good point, I added the line:

$submit = $_POST['submit'];

before the if(isset) at the top of the main script, but it has, unfortunately, not fixed the problem. The variables are still not being posted.

I'm also getting a "Warning: strpos(): Empty delimiter. in /global.php(349) : eval()'d code on line 9" from your forum when I post. This is line 9:

	if ($submit=="Test")

. Can someone tell me what's wrong with it? Thanks so much!

That error must be an error on the forums, not with your code... I'll have to look into that...

As for your code, where is $title ever defined (in the SQL portion)? Also note that you have a syntax error in that script (look at the syntax highlighting when you posted it).

Oh for heaven's sake!

Well, I figured out the problem. Here's my corrected form:

<html>
<font face="arial">
<title>Univelt Data</title>
<body>
<form method="post" action="<?php echo $_SERVER['SCRIPT_NAME' ?>">
<?php
$submit = $_POST['submit'];

if (isset($_POST['submit']))
{
	if ($submit=="Test")
	{ include "IncludeVariables.php";
	include "IncludeHiddenForm.php";
	include "IncludeHTML.php"; }

elseif ($submit=="Insert into Database")
{ include "IncludeVariables.php";
include "IncludeHiddenForm.php";
include "IncludeInsert.php"; }
else
{ echo "Submit button value not properly defined."; }
}
else
{ include "IncludeForm.php"; }

?>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Test">
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Insert into Database">
</form>
</html>

<p>

I think I've corrected the syntax, but please let me know if I missed something. The problem was the lack of a

</FORM>

tag at the end. sighs I also changed the placement of the "<form method="post" action="<?php echo $_SERVER['SCRIPT_NAME' ?>">" to the beginning of the form so that the "IncludeForm" was actually included inside the form tags.

Thank you for your help. Maybe this will help someone else having a similar problem!

P.S. The $title variable was defined in the IncludeVariables.php include script. As of right now, everything appears to be working the way it's supposed to.
