สอบถามเรื่องการทำ Dropdown จากดาต้าเบสหน่อยครับ มันไม่แสดงออกมาครับ

<?php 
foreach($rs as $key =>$value) {
	echo "<option value='".$key."'
	if($_POST['id_dic'] == $key)
		echo "selected='selected'";
	>".$value."</option>"; 
}
?>

 <?php 
	foreach($rs as $key =>$value) {
		$slc=$_POST['id_dic'] == $key? 'selected' : '';
	  	echo "<option value='$key' $slc >$value</option>"; 
	}
?>

<?php 
								$db = JFactory::getDBO();
								$strSQL =  " SELECT * From tb_k2_dic where tb_k2_dic.id ";
								$db->setQuery($strSQL);
								//$rs = $db->loadObjectList();
								//return $rows1;
								$rs = $db->loadAssocList();
								print_r ($rs);
								//exit;
								 ?>
								 <tr>
								 <td class="adminK2LeftCol">
										<label><?php echo JText::_('K2_DIC'); ?></label>
								</td>
								 <td>
								<select name="id_dic">
								   <?php 
									foreach($rs as $item1 =>$id) {
										$slc=$_POST['dic_name_thai'] == $item1? 'selected' : '';
										echo "<option value='$item1' $slc >$id</option>"; 
									}
									?>

								</select>

<?php 
	foreach($rs as $key =>$row) {
		$slc=$_POST['id_dic'] == $row->id ? 'selected' : '';
	  	echo "<option value='$row->id' $slc >$row->id</option>"; 
	}
?>

//กรณี $row เป็น array
<?php 
	foreach($rs as $key =>$row) {
		$slc=$_POST['id_dic'] == $row['id']? 'selected' : '';
	  	echo "<option value='$row[id]' $slc >$row[id]</option>"; 
	}
?>
