sql - outputting values from database into html table PHP

Question

I have the code below which grabs data from a table based on what week the user has chosen, there are only 2 possible weeks to choose from.

It puts the title of the recipe into the relevant table based on the if statement but seems to be producing weird output.

When ever i try to view a week which only has part data filled in it bunches of the data onto the wrong cells; look in this image: 'Salad' located on the top row should be in 'Sunday'

This only happens when the table is incomplete.

 if(!empty($_POST['selectweek'])) {
                        $selectweek = mysql_real_escape_string($_POST['selectweek']);

                        function ouptutMeal($selectweek, $mealtime, $mealname) {
                            $sqlmeasurement2 = mysql_query("SELECT title, dayid
                                                            FROM recipe
                                                            JOIN menu ON recipe.recipeid = menu.recipeid
                                                            WHERE menu.weekid = '$selectweek'
                                                            AND menu.mealtimeid = '$mealtime'
                                                            ORDER BY dayid");

                            echo "<br/>
                                <table>

Answer 1

Do an if statement to see if a value exists if not then

   <td>& nbsp;</td>

so it fills your table correctly.
