I've created a .php file that users will access via hyperlink within our web portal to download a database to a CSV file and I can get it to download the entire database but I only want to export the columns FirstName LastName Postcode & Email.
What do I add/amend to the code below to do this? I assume it's in the mysql_query line but can't figure out the command todo this.
<?php
// Database Connection
$host="localhost:/tmp/mysql5.sock";
$uname="dbo1234567";
$pass="password";
$database = "db1234567";
$connection=mysql_connect($host,$uname,$pass);
echo mysql_error();
//or die("Database Connection Failed");
$selectdb=mysql_select_db($database) or
die("Database could not be selected");
$result=mysql_select_db($database)
or die("database cannot be selected <br>");
// Fetch Record from Database
$output = "";
$table = "tbl_Coach"; // Enter Your Table Name
$sql = mysql_query("select * from $table");
$columns_total = mysql_num_fields($sql);
// Get The Field Name
for ($i = 0; $i < $columns_total; $i++) {
$heading = mysql_field_name($sql, $i);
$output .= '"'.$heading.'",';
}
$output .="
";
// Get Records from the table
while ($row = mysql_fetch_array($sql)) {
for ($i = 0; $i < $columns_total; $i++) {
$output .='"'.$row["$i"].'",';
}
$output .="
";
}
// Download the file
$filename = "coachdb.csv";
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
echo $output;
exit;
?>
