Exclude DB Columns
Posted: Thu Jul 05, 2012 3:20 pm
Hi.
I am attempting to add a function that will create a csv for download from a certain table in the db. I have got it partially working but cannot figure out how to exclude certain columns from the rows section of the csv. Here is my code so far,
What I would like to do is also exclude the columns invhead_id and note from the rows output but so far all things I have tried have failed. Can anyone point me in the right direction?
Thanks
I am attempting to add a function that will create a csv for download from a certain table in the db. I have got it partially working but cannot figure out how to exclude certain columns from the rows section of the csv. Here is my code so far,
Code: Select all
$host = 'xxx';
$user = 'xxxx';
$pass = 'xxxx';
$db = 'xxxx';
$table = 'headers';
$file = 'export';
$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");
$link = mysql_connect($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." WHERE Field NOT IN ('invhead_id', 'note');");
$i = 0;
if (mysql_num_rows($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";
}
print $csv_output;
exit;Thanks
