It requires a file called "list.txt" to exist. <? if (isset ($item)) { $fp = fopen("list.txt", "a"); fputs ($fp, "<tr><td>$item</td></tr>\r\n"); header ("Location: $PHP_SELF"); exit(); } ?> <table border="1" cellspacing="2"> <? readfile("list.txt"); ?> </table> <br><br> <form method="post" action="<? echo ($PHP_SELF); ?>"> <p>Add Item: <input type="text" name="item"></p> <p><input type="submit" name="Add" value="Add"></p> </form>
