Use this code:
<?php if (empty($_POST) { ?>
<form action="" method="post">
 <input type="checkbox" id="checkbox_row_6" value="apples"
name="selected_fld[]" />
 <input type="checkbox" id="checkbox_row_7" value="oranges"
name="selected_fld[]" />
 <input type="checkbox" id="checkbox_row_8" value="bananas"
name="selected_fld[]" />
 <button type="submit">Submit<button>
</form>
<?php
 } else echo '<pre>', print_r($_POST, true), '</pre>';
?>

This will print out the postdata, along with the "secrets" to how this works.
