Hi,
If someone here is willing to help me I would really appreciate
how to limit the addition of columns in the following html code, let say only up to 5 only?
PHP Code:
<form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" id="friends"
<table width="100%" cellpadding="10" cellspacing="0" id="my_friends">
<tr>
<th colspan="2" style="text-align: center;"><?php echo $text_enter_friend; ?></th>
</tr>
<tr>
<td class="left" width="30%"><span class="required">*</span> <?php echo $entry_friend; ?></td>
<td class="left"><input type="text" name="friend" value="<?php echo $friend; ?>" size="30" maxlength="45" />
<?php if ($error_friend) { ?>
<span class="error"><?php echo $error_friend; ?></span>
<?php } ?></td>
</tr>
<?php if ($friends) { ?>
<?php foreach ($friends as $result) { ?>
<tr>
<td style="vertical-align: top;"><?php echo $entry_friend; ?></td>
<td style="vertical-align: top;"><input type="text" name="friends[]" value="<?php echo $result; ?>" size="30" maxlength="45" /></td>
</tr>
<?php } ?>
<?php } ?>
</table>
<table width="100%" cellpadding="10" cellspacing="0">
<tr>
<td></td>
<td class="right"><a onclick="addFriend();" class="button"><span><?php echo $button_add_friend; ?></span></a><a onclick="removeFriend();" class="button"><span><?php echo $button_remove; ?></span></a></td>
</tr>
<tr>
<td colspan="2" class="center">
<p><?php echo $text_message; ?></p>
<p><a onclick="$('#friends').submit();" class="button"><span><?php echo $button_submit; ?></span></a></p>
<p><?php echo $text_addresses; ?></p>
</td>
</tr>
</table>
</div>
</form>
Code:
<script type="text/javascript"><!--
function addFriend() {
var tbl = document.getElementById('my_friends');
var iteration = tbl.tBodies[0].rows.length;
newRow = tbl.tBodies[0].insertRow(-1);
var newCell = newRow.insertCell(0);
newCell.innerHTML = '<?php echo $entry_friend; ?>';
var newCell1 = newRow.insertCell(1);
var el = document.createElement('input');
el.type = 'text';
el.name = 'friends[]';
el.size = 30;
el.maxlength = 45;
newCell1.appendChild(el);
// if (newCell > 2) tbl.addCell(newCell + 1);
}
function removeFriend() {
var tbl = document.getElementById('my_friends');
var lastRow = tbl.rows.length;
if (lastRow > 2) tbl.deleteRow(lastRow - 1);
}
//--></script>
Thanks in advance |
