using variable from array outside of foreach loop - php

Question

Im trying to display variables from an array. I am using a foreach loop, however I need to display $order['campaign_name'] before the loop so that it only shows up once. How can I do this? If I change it to $orders['campaign_name'] I get an undefined index error.
<div class="table-responsive">
<table class="table" id="component-table">
<?php if ($orders) { ?>
<?php foreach ($orders as $order) { ?>
<thead>
<tr>
<td colspan=100%><h3><?php echo $order['campaign_name']; ?></h3></td>
</tr>
</thead>
<tbody>
<tr class="campaign-list" id="campaign-list">
<td><?php echo $order['component_name']; ?></td>
<td><?php echo $order['component_owner']; ?></td>
<td><?php echo $order['component_date']; ?></td>
<td><?php echo $order['campaign_code']; ?></td>
</tr>
<?php } ?>
<?php } else { ?>
<tr>
<td class="text-center" colspan="8"><?php echo $text_no_results; ?></td>
</tr>
<?php } ?>
</tbody>
</table>
</div>

Answer 1

You are trying to get those value which is not exist before loop. You are directly calling VALUE.
Easily just put index value behind tha array
echo $orders[0]['campaign_name']
It will print your value.

Answer 2

You would need need to know which index of the array you want to show, but if you want to show the first index of the array you can use $orders[0]['component_name'].
<div class="table-responsive">
<table class="table" id="component-table">
<?php if ($orders) { ?>
<thead>
<tr>
<td colspan=100%><h3><?php echo $orders[0]['campaign_name']; ?></h3></td>
</tr>
</thead>
<tbody>
<?php foreach ($orders as $order) { ?>
<tr class="campaign-list" id="campaign-list">
<td><?php echo $order['component_name']; ?></td>
<td><?php echo $order['component_owner']; ?></td>
<td><?php echo $order['component_date']; ?></td>
<td><?php echo $order['campaign_code']; ?></td>
</tr>
<?php } ?>
</tbody>
<?php } else { ?>
<tbody>
<tr>
<td class="text-center" colspan="8"><?php echo $text_no_results; ?></td>
</tr>
</tbody>
<?php } ?>
</table>
</div>

Answer 3

Your campaign name continues to echo out because you have it inside of your foreach loop; if you want it to display only once, make sure to place it above your foreach loop.
Here's a less cluttered example to learn from:
<table>
...
<?php
if ($orders):
echo $order['campaign_name'];
foreach($orders as $order):
echo '...'; // other components
endforeach;
else:
echo $text_no_results;
endif;
?>
...
