Question

With help from others on here, I’ve got a nested loop on the go that pull a list of months from one sql table and then, for each of those months, it goes through an events table and pulls the respective events.

Table structures are along the lines of:

MonthTable

ID  | MonthShort |  MonthLong
1 | 2012Oct | October 2012
2 | 2012Sep | September 2012 

---

EventTable

ID | MonthID | Event | Guests | Adults | Children
1 | 1 | Wedding | 200 | 150 | 50
2 | 1 | Bar Mitzvah | 100 | 50 | 50
3 | 1 | Funeral | 100 | 50 | 50 
4 | 2 | Birthday | 50 | 30 | 20 
5 | 2 | Birthday | 300 | 200 | 100
6 | 2 | Wedding | 200 | 180 | 20

My loop works so that it populates menu A with all available months, then populates menu B with all of the events for that month. You can then click on the event and it displays the relevant information – this is where I’m a bit stuck.

The arrays I’ve got are similar to the following, the guests array is what I’m trying out atm:

$events = array();
$months = array();
$guests = array();

while ($row = mysql_fetch_array($result)) {
  $months[$row["MonthID"]] = $row["MonthLong"];
  $events[$row["MonthID"]][] = $row["Event"];
  $guests[$row["MonthID"]][] = $row["Guests"];
}

I use a foreach to populate menu B with ($events[$x] as $event). The screen for each event will have an entry similar to the following and this is what I’d like to do (obviously I know this won’t work bu it should serve for illustrative purposes):

echo ‘ Number of guests: ‘ . print_r($guests[$x])

With guests and events both on the same counter I though it would allow me to print the array entry in the relevant position.

So what I’d like it if you click on “October 2012” and then select “Funeral“, the screen would say:

Number of guests: 100

There are actually several dozen records per event but no point going into all of them…

Apologies for the rambling and if this makes no sense! I’m new to PHP and am only really stuck on this bit.

SQL query is built on the following:

$sql = "
  SELECT
    a.id, b.id AS monthId, a.event, b.monthshort, b.monthlong
  FROM
    events_table_name AS a
  INNER JOIN
    month_table_name AS b ON b.id = a.monthId
  ORDER BY
    b.id, a.id ASC
  ";

You need make use of the index in the foreach statement. I mean

foreach ($events[$x] as $i => $event) {
    ...
    echo ' Number of guests: ' . print_r($guests[$x][$i]);
}
