Hi
Pls refer bellow mentioned code… this code will prompt 2 hyperlinks when we click that it will export the result to CSV file…
My problem is i can set the conditions in where clause for 2 links individually… but i need to select the different table columns… example for these 2 csv export links, i can set the condition in
[php]‘where’=>“WHERE id=1”,[/php]
But i got only 1 definition :
[php]$sql_query = "select * from $table ".$where;[/php]
can anyone advise me how can i have different select query for these 2 links individually? so i can select any column from tbl1 or tbl2
for example i need something like this :
[php]
$sql_query1 = "select id,name from $table ".$where;
$sql_query2 = "select firstname,lastname from $table ".$where;
$sql_query3= "select location from $table ".$where;
[/php]
This is the full code :
[php]<?php

$sql_query = "select * from $table ".$where;
// Gets the data from the database
$result = mysql_query($sql_query);
$fields_cnt = mysql_num_fields($result);
$schema_insert = '';
for ($i = 0; $i < $fields_cnt; $i++)
{
$l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed,
stripslashes(mysql_field_name($result, $i))) . $csv_enclosed;
$schema_insert .= $l;
$schema_insert .= $csv_separator;
} // end for
$out = trim(substr($schema_insert, 0, -1));
$out .= $csv_terminated;
