You have defined a function, as long as the function isn't executed, it won't
do anything.
The function has a major disadvantage, it don't return a value or use a global
value, so even if it's executed, the $result you have in the
<input type="text" name="outcome" <?php echo "VALUE=\"$result\"" ?>>
isn't the same as the $result in your result_get().
for the second, the $result (return value from mysql_query()) isn't the actual
output from the sql query, it's a resource used to access the data you want.
$date=mysql_fetch_array($result);
?>
<input type="text" name="price">
<input type="submit" value="hit me">
<input type="text" name="outcome" <?php echo "VALUE=\"$date['result']\"" ?>>
</form>
mysql_fetch_array() does return an array of the columns for _one row_ data
from the query you have made. If you want to get out more than one row you
need to use the function more than once.
