Question

I need some help figuring out this for loop logic. I know exactly what I want to do, but I sadly can’t seem to get to it.

This is my code at the moment.

<? foreach($ticket_details as $ticket): ?>
  <tr class="tableBG" style="background-color: #fc6">
    <td align="center"><?= $ticket['name']; ?></td>
    <td align="center"><?= $ticket['price']; ?></td>
    <td align="center"><?= $ticket['priceWithinAllocation']; ?></td>
    <? for($i = 0; $i < $event_details['number_of_days']; $i++): ?>
      <? 
      foreach($ticket['days'] as $key => $value)
      {
        if($value == date('Y-m-d', strtotime($event_details['startDate'] . "+ $i day")))
        {
          echo "<td>&#10003;</td>";
        }
        else
        {
          echo "<td>--</td>";
        } 
      }
      ?>
    <? endfor; ?>
    <td align='center'>
      <input type='button' class='remove' id='remove[ticket][<?= $ticket['ticketID'] ?>]'  value='REMOVE' />
    </td>
  </tr>
<? endforeach; ?>

This doesn’t really work.

My tickets array looks like this:

    [5] => Array
    (
        [ticketID] => 5
        [eventID] => 1
        [name] => Thu
        [price] => 500
        [priceWithinAllocation] => 250
        [day] => 2011-08-25
        [days] => Array
            (
                [0] => 2011-08-25
            )

    )

[6] => Array
    (
        [ticketID] => 6
        [eventID] => 1
        [name] => Wed+Thu
        [price] => 900
        [priceWithinAllocation] => 110
        [day] => 2011-08-24
        [days] => Array
            (
                [0] => 2011-08-24
                [1] => 2011-08-25
            )

    )

When $ticket['days'] contains more than one value, it prints out too many empty (–) <td>. I’m not sure how to do the loop without having it print more than I need. Here’s a screenshot of what happens with this code:

I tried some stuff with if(count($ticket['days'])) { } but that didn’t work out. So now I’m stuck.

I realise this is a fairly vague question because I didn’t provide too much code here; if needed, I can provide more, but there’s a lot of stuff going on so I kept it to a minimum.

Thanks in advance.

You print a cell for each date in $ticket[‘days’]. That’s why you get too much cells.

Try this :

<? foreach($ticket_details as $ticket): ?>
  <tr class="tableBG" style="background-color: #fc6">
    <td align="center"><?= $ticket['name']; ?></td>
    <td align="center"><?= $ticket['price']; ?></td>
    <td align="center"><?= $ticket['priceWithinAllocation']; ?></td>
    <? for($i = 0; $i < $event_details['number_of_days']; $i++): ?>
      <? 
      $foundDate = false;
      foreach($ticket['days'] as $key => $value)
      {
        if($value == date('Y-m-d', strtotime($event_details['startDate'] . "+ $i day")))
        {
          $foundDate = true;
        }
      }
      if($foundDate)
      {
        echo "<td>&#10003;</td>";
      }
      else
      {
        echo "<td>--</td>";
      } 
      ?>
    <? endfor; ?>
    <td align='center'>
      <input type='button' class='remove' id='remove[ticket][<?= $ticket['ticketID'] ?>]'  value='REMOVE' />
    </td>
  </tr>
<? endforeach; ?>
