YES this works thank nemeth:
<?php
function previewString($showcatvar) {
$minitxt = $showcatvar;
$len = strlen($minitxt);
if ($len > 235)
{
$len = 235;
}
else
{
$len = $len;
}
$newstring = substr($minitxt,0,$len);
$previewtext = $newstring;
return $previewtext;
}
?>
and to display it:
<?php echo previewString($row_show_cat['text']); ?>
cheers
