Hi,

I have been trying to generate an excel report from MySQL database. The query is working fine but the excel contains a lot of junk data along with the valid result. I have provided the source code file along with this post. Please let me know what am i doing wrong.

Regards,
Kush

Code: Select all

 
<?php
    defined('_JEXEC') or die('Restricted Access');
    $file = getcwd();//Get the current working directory
?>
<html>
    <head>
        <script type="text/javascript" src="<?=$file;?>\components\com_content\lightbox\lightbox.js"></script>
        <link rel="stylesheet" href="<?=$file;?>\components\com_content\lightbox\lightbox1.css" />
    </head>
</html>
<?php
    //Some other code
    Call to function exportlist()
    }
    function exportlist(){
        $file = getcwd();
        $eventId = JRequest::getVar('eveid');
        require_once("$file\configuration.php");
        $config = new JConfig();
 
        $host = $config->host;
        $user = $config->user;
        $pass = $config->password;
        $db = $config->db;
        $file = 'export';
 
        $conn = mysql_connect($host,$user ,$pass) or die ("Could not connect to host:".mysql_error());
        $db_selected = mysql_select_db($db,$conn) or die ("Could not connect to database:".mysql_error());
 
        $result = mysql_query("select firstname,lastname from jos_comprofiler where user_id IN(Select userid from jos_jev_register where eventid = $eventId)", $conn) or die ("Could not execute query:".mysql_error());

        $xlsRow = 1;
 
        // Put data records from mysql by while loop.
        while($row=mysql_fetch_array($result)){
        xlsWriteLabel($xlsRow,0,"$xlsrow");
        xlsWriteLabel($xlsRow,1,"$row[firstname]"."$row[lastname]");
 
        $xlsRow++;
        }
        xlsEOF();
        exit();
    }
    function xlsBOF() {
        echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
        return;
    }
    function xlsEOF() {
        echo pack("ss", 0x0A, 0x00);
        return;
    }
    function xlsWriteNumber($Row, $Col, $Value) {
        echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
        echo pack("d", $Value);
        return;
    }
    function xlsWriteLabel($Row, $Col, $Value ) {
        $L = strlen($Value);
        echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
        echo $Value;
        return;
    }
