I am trying to retrieve the values stored in my database when the user selects the data from the selection list and also i am using 2 radio buttons, when 1st radio button is checked. When 1st radio button is checked , get the data from table1 and if the 2nd radio button selected get the data from table2. How can i do it?

Please somebody help me.

HTML:

<input type="radio" name="table" value="1" />
<input type="radio" name="table" value="2" />

PHP:

$tables = array(
  1 => 'table_1',
  2 => 'table_2'
);
if (!isset($_GET['table'],$tables[$_GET['table']])) {
  exit("Invalid table selected");
}
$tableName = $tables[$_GET['table']];
$query = "SELECT * FROM $tableName";

By using the lookup table $tables, the user input is effectively sanitised because it is never used directly in a query.
