I am trying to export a dynamically created table (one that has been filtered from user inputs) into a csv file format.  I have simplified the database and code for ease of use.  I also have generated the export file which will extract all information from the table in the database, but I need the information that is filtered by the user to be extracted.  Files are shown below.

 

How might I modify my export.php file (or other files) to accomplish this?

 

Thanks in Advance

 

 

export.php

<?php

include 'config.php';

$table = 'user';
$file = 'export';

$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field'].", ";
$i++;
}
}
$csv_output .= "\n";

$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
} 

$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
print $csv_output;
exit;
?>

 

config.php

<?php
$con = mysql_connect('localhost', 'root', '');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("test", $con);
?>

 

index.php

<?php
include('config.php');  //Include the database connections in it's own file, for easy integration in multiple pages.

$lastname_result = mysql_query("SELECT lastname FROM user GROUP BY lastname");

$result = mysql_query("SELECT * FROM user");

?>
