form error checking type="file"

stu10001

I wonder if any body can help me, i am checking to see if the required fields in a HTML form are filed in. I have managed to check the (input type="text") fields, but when i try to check an (input type="file") field as been input it just ignores it. Here is my error checking:

// set up error list array
$errorList = array();
$count = 0;

// validate text input fields

if (!$product) { $errorList[$count] = "Please input Product name"; $count++; }
         if (!$form_data) { $errorList[$count] = "Please input a Picture"; $count++; }

// check for errors
// if none found...
if (sizeof($errorList) == 0)
{
   MYSQL_CONNECT("$host","$user","$pass");
mysql_select_db("$db");

blah, blah blah......

}
else
{
// errors found
// print as list
echo "The following errors were encountered:";
echo "<ul>";
for ($x=0; $x<sizeof($errorList); $x++)
{
	echo "<li>$errorList[$x]";
}
echo "</ul><a href=javascript:history.back(-1)> go back</a>";
}

I just cant figure out how to check the variable $form_data as its from an <input type="file" name="form_data">

Thanks in advance

try this
if ($form_data=="none") { $errorList[$count] = "Please input a Picture";
$count++;
}

if this doesnt work, leave the $form_data value blank, submit the file, and to see what its value is when its blank, do this

echo "form data is ".$form_data;

then use the value to check in the if($form_data=="use that value here") condition
