[semperfi]

Hi can anybody help I need to export and download tables from a database into a excel sheet. I have this code and it works what I need is to export specific fields and not just the whole table can anyone help modifying the code to export certain fields within the table please? Here is the code...

<?php
$host = 'localhost';
$user = 'user';
$pass = 'password';
$db = 'qdbname';
$table = 'tablename';
$file = 'export';

$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");

$result = mysql_query("SHOW COLUMNS FROM ".$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;
?>

Try this, using a fields array.

 

<?php
$host = 'localhost';
$user = 'user';
$pass = 'password';
$db = 'qdbname';
$table = 'tablename';
$file = 'export';
$fields = array('field1', 'field2', 'field3', 'field4');

$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");

$csv_output .= implode('; ', $fields);
$csv_output .= "; \n";

$values = mysql_query("SELECT ".implode(',', $fields)." FROM ".$table);
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<count($fields);$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;
?>
