Answer 1

This is too long for a comment as I tried explaining it in there, but felt it would be better if it were represented in an answer.

Nota: I also changed $_FILES['uploadedfile'] to $_FILES['photo'] since that would generate an error.

Move everything starting from $target = "images/"; down to echo "<center>Photo ". basename... then placed under if (isset($_POST['submit'])){ then modify that conditional statement to read as if (isset($_POST['submit']) && !empty($_FILES['photo'])){ and you should be good to go.

Here's a rewrite:

<?php

 // creates the new record form
 // since this form is used multiple times in this file, I have made it a function that is easily reusable
 function renderForm($sname, $fname, $error)
 {
 ?>
<?php 
 // if there are any errors, display them
 if ($error != '')
 {
 echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>';
 }
 ?>
