How to call results in Wordpress page

[Jim123]

Really stupid, but I canīt figure it out.

I have two files. One is the form

<div id="container">
<div id="content" role="main">
 
<form action="/vitamine/wp-content/themes/twentyten/insert.php" method="post">
Value1: <input type="text" name="value1"><br>
<input type="Submit">
</form> 

</div><!-- #content -->
</div><!-- #container -->


<?php get_footer(); ?>

and the other one is insert.php to get the results

<?php
$username="root";
$password="";
$database="test";

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT Shrt_Desc, Vit_D_mcg, Water, Energ_Kcal, Protein, Lipid_Tot, Carbohydrt FROM abbrev WHERE Shrt_Desc LIKE '%".mysql_real_escape_string($_POST['value1'])."%' ORDER BY Vit_D_mcg DESC ";
$result=mysql_query($query) or die("could not execute query: " . mysql_error()); 
while ($row=mysql_fetch_array($result)) { 
 $results .= '<tr> 
 <td>' . $row['Shrt_Desc'] . '</td> 
 <td>' . $row['Vit_D_mcg'] . '</td> 
 <td>' . $row['Water'] . '</td> 
 <td>' . $row['Energ_Kcal'] . '</td> 
 <td>' . $row['Protein'] . '</td> 
 <td>' . $row['Lipid_Tot'] . '</td> 
 <td>' . $row['Carbohydrt'] . '</td> 
 </tr>'; 
} 
mysql_close(); 
// 
if ($results) { 
 echo "<table border=\"1\" align=\"center\" cellpadding=\"2\" cellspacing=\"2\"> 
 <tr><td>NAME</td><td>Vit D mcg</td><td>Water</td><td>Energy</td><td>Protein</td><td>Fat</td><td>Carbohydrate</td></tr> 
 $results 
 </table> 
 "; 
} 
else { echo "<p>No results were found with that search.</p>"; } 
?> 

I want the results showing up in the Wordpress Twentyten theme, but whatever I do, I canīt get further than having the results on a blank page.

I tried

<?php
$username="root";
$password="";
$database="vitaminen";

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT Shrt_Desc, Vit_D_mcg, Water, Energ_Kcal, Protein, Lipid_Tot, Carbohydrt FROM abbrev WHERE Shrt_Desc LIKE '%".mysql_real_escape_string($_POST['value1'])."%' ORDER BY Vit_D_mcg DESC ";
$result=mysql_query($query) or die("could not execute query: " . mysql_error()); 
while ($row=mysql_fetch_array($result)) { 
 $results .= '<tr> 
 <td>' . $row['Shrt_Desc'] . '</td> 
 <td>' . $row['Vit_D_mcg'] . '</td> 
 <td>' . $row['Water'] . '</td> 
 <td>' . $row['Energ_Kcal'] . '</td> 
 <td>' . $row['Protein'] . '</td> 
 <td>' . $row['Lipid_Tot'] . '</td> 
 <td>' . $row['Carbohydrt'] . '</td> 
 </tr>'; 
} 
mysql_close(); 
// 
if ($results) {

get_header(); ?>

<div id="container">
<div id="content" role="main">

<?php
 echo "<table border=\"1\" align=\"center\" cellpadding=\"2\" cellspacing=\"2\"> 
 <tr><td>NAME</td><td>Vit D mcg</td><td>Water</td><td>Energy</td><td>Protein</td><td>Fat</td><td>Carbohydrate</td></tr> 
 $results 
 </table> 
 "; 
} 
else { echo "<p>No results were found with that search.</p>"; } 
?> 

</div><!-- #content -->
</div><!-- #container -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

but that gives me this errorą
Fatal error: Call to undefined function get_header() in C:\xampp\htdocs\test\wp-content\themes\twentyten\insert.php

Iīm a bit stuck at the moment. Anyone with suggestions?
Thanks
