  • Content headers
  • Formatted Printing

Below, I'll show you an example which combines the two elements above with a database query:

Notes:

  • Notice the format in printf.  We're using %s to represent a string, and \t as an escape character to represent a TAB
  • We're assuming that you've already setup a database connection with mysql_connect.

 

<?php

header("Content-Disposition: attachment; filename=\"quotes.tsv\"");
header("Content-Type: text/tab-delimited-values");
 
 $sql = "SELECT
               client,
               address,
               city,
               state,
               postal,
               phone,
               email
            FROM quote";
       
$res = mysql_query($sql, $connection)

echo "Client\tAddress\tCity\tState\tZip\tPhone\tE-Mail\n";

while ($row = mysql_fetch_array($res)) {


    printf("%s\t%s\t%s\t%s\t%s\t%s\t%s\n",
            $row['client'],
            $row['address'],
            $row['city'],
            $row['state'],
            $row['postal'],
            $row['phone'],
            $row['email'],
            );
   
}

?>

If you want additional control, combine CFDocument with CFHeader as follows:

<cfcontent type="application/pdf">
<cfheader name="Content-Disposition" value="attachment;filename=export.pdf">

<cfdocument format="PDF">
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <title>Hello World</title>
</head>
<body>
    Hello World
</body>
</html>
</cfdocument>

This presents a problem when storing a zip file on the file system, especially when the need arises to overwrite that zip file. The solution we've come up with is to first use CFFile to create an empty file, and make it writeable.

<cffile action="write" file="#mypath#/#myfile#.zip" output=" " mode="777">

<cfzip file="#mypath#/#myfile#.zip" action="zip" overwrite="true">
