Hi all,
I wonder if anyone can give me some idea; I have a form with a drop down menu [BT,Virgin, None, Other] - When user select either [BT, Virgin,None] the textarea field will be disable. But when user select option [Other] the textarea will be available.
How can I do this?
..
..
<tr align="left" valign="top" <?php if ($_POST['action'] == "register") { if ($errornum[16] == "1") { echo 'class="error"'; } } ?>>
<td>Who is your previous Internet Service Provider?</td>
<td align="left">
<select name="oldprovider">
<option value="<?php echo $prev_supplier;?>" <?php if ($_POST['action'] == "register") { if ($_POST['oldprovider'] == "") { echo "selected"; } } ?>>
Select Provider.....
</option><?php $prev_supplier="BT";?>
<option value="<?php echo $prev_supplier;?>" <?php if ($_POST['action'] == "register"){ if ($_POST['oldprovider'] ==
"$prev_supplier") { echo "selected"; } } ?>>
<?php echo $prev_supplier;?>
</option><?php $prev_supplier="Virgin";?>
<option value="<?php echo $prev_supplier;?>" <?php if ($_POST['action'] == "register") { if ($_POST['oldprovider'] ==
"$prev_supplier") { echo "selected"; } } ?>><?php echo $prev_supplier;?>
</option><?php $prev_supplier="None";?>
<option value="<?php echo $prev_supplier;?>" <?php if ($_POST['action'] == "register") { if ($_POST['oldprovider'] ==
"$prev_supplier") { echo "selected"; } } ?>><?php echo $prev_supplier;?>
</option><?php $prev_supplier="Other";?>
<option value="<?php echo $prev_supplier;?>" <?php if ($_POST['action'] == "register") { if ($_POST['oldprovider'] ==
"$prev_supplier") { echo "selected"; } } ?>><?php echo $prev_supplier;?>
</option>
</select>
<br /><br />
<textarea name="oldprovider_text" cols="30" rows="2">
<?php if ($_POST['action'] == "register") { echo $_POST['oldprovider_text']; } ?>
</textarea></td>
</tr>
Thanks in advance.
