    I have a basicc form that takes users info and when they submit it it show on a new web page in the proper order. I need to know how do I skip a blank field. This form takes a users First, Middle, and Last name but many times they leave the middle name blank so I would want to skip this field from showing up when the form is posted. Here is what I have for the basic php script ..Would like to know how to skip a field if it is left blank on the form.

    echo $_POST["First"], print "."; ?><?php echo $_POST["Middle"], print "."; ?><?php echo $_POST["Last"], print "."; ?><?php echo $_POST["Persona1"], print ".";<br />

    Using your output formatting...

    <?php

echo $_POST['First'];
echo '.';
if((isset($_POST['Middle'])) && (strlen(trim($_POST['Middle']))))
{
    echo $_POST['Middle'];
    echo '.';
}
echo $_POST['Last'];
echo '.';

?>
