PHP / MYSQL的空白页面

Question

I am working on a snippet of code recycled from another location and the original works fine but the modified one just gives me a blank page. I have tried commenting out sections in hopes of isolating the problem but I keep hitting a road block. I know it is something simple and something I am overlooking but I my brain hurts now and figured I would post it on here while I went outside to scream at passing cars to relieve some frustration.

    <TITLE> Add Item </TITLE>
<?php

include("dbc.php");

if(isset($_POST['submit']))
        {
        $material = $_POST['material'];
        $dimmention = $_POST['dimmention'];
        $size = $_POST['length'];
        $color = $_POST['color'];

        if(!$material)
                {
                echo "Error: Material is a required field. Please fill it.";
                exit();
                }

        $result = mysql_query("INSERT INTO list (mat, date, dim, size, color)
        VALUES ('$material',NOW (),'$dimmention','$size','$color')",$connect);
        echo "<b>Thank you! Item added Successfully!<br>You'll be redirected to Home Page after (4) Seconds";
        echo "<meta http-equiv=Refresh content=4;url=index.php>";

        }
else
        {
        ?>
        <br>
        <h3>::Add Item</h3>
        <form method="post" action="<?php echo $_SERVER[PHP_SELF] ?>">
        Material (Alum, Galv, Steel): <input name="material" size="6" maxlength="6">
        <br>
        Dimentions (1 x 2 Patio, 2 x 2 090): <input name="dimmention" size="50" maxlength="100">
        <br>
        Size (24, 30, 15): <input name="length" size="5" maxlength="5">
        <br>
        Color (bronze, white, MF): <input name="color" size="6" maxlength="6">
        <br>
        <input type="submit" name="submit" value="Add Item">
        </form>
        <?
        }

?>

Thanks to all who can help.

Answer 1

My initial assumption is that you have short open tags turned off in your ini file. Change the bottom of the page from this:

<?

  }

?>

To this:

<?php

  }

?>
