Great tutorial,
To all those that have the problem with the slashes showing up in front of the quotes, here is what will fix it:
Replace the textarea section with this bit of code:
<?php break;
case 'textarea': ?>
<?php $input = get_settings( $value['id'] ); $output = stripslashes ($input); ?>
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?php echo $value['name']; ?></strong></td>
<td width="80%"><textarea name="<?php echo $value['id']; ?>" cols="60" rows="15"><?php if ( get_settings( $value['id'] ) != "") { echo $output; } else { echo $value['std']; } ?></textarea></td>
</tr>
<tr><td><small><?php echo $value['desc']; ?></small></td></tr>
<tr><td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td></tr><tr><td colspan="2"></td></tr>
^^That will get rid of the slashes on the options page, and to get rid of the slashes in the display when you call the variable use:
echo stripslashes($variablename);
instead of just calling the variable.
Someone mentioned magic quotes, but that is not a good option because it has been deprecated from the PHP standard
