Hi all,
I’m trying to pull pilots awards in but having some trouble. If a pilot has an award this code works perfectly. However, if a pilot has NOT received an award yet I get an error. Does anyone know how to create an “if” statement that addresses an empty array?
error received: Warning : Invalid argument supplied for foreach()
\<strong\>Awards\</strong\> \<li class="list-group-item"\>\<?php echo "\<table\>"; echo "\<tr\>" ; $i = 0; foreach ($allawards as $award) { if ($i % 5 === 0) { echo '\</tr\>\<tr\>'; } echo "\<td\> \<img src=".$award-\>image." alt=".$award-\>name." /\>\<br\>".$award-\>name." \</td\>"; $i++; } echo "\</tr\>" ; echo "\</table\> "; ?\> \</ul\>
Has that pilot been awarded an award yet?
if (isset($allawards)) { foreach ($allawards as $award) { if ($i % 5 === 0) { echo '\</tr\>\<tr\>'; } echo "\<td\> \<img src=".$award-\>image." alt=".$award-\>name." /\>\<br\>".$award-\>name." \</td\>"; $i++; } }
Try this code
Vangelis,
Outstanding! That works great!

Alternatively, you can do the following:
if(!$allawards) { echo '\<td align="center"\> No Rewards Yet! \</td\>'; } else { foreach ($allawards as $award) { if ($i % 5 === 0) { cho '\</tr\>\<tr\>'; } echo "\<td\> \<img src=".$award-\>image." alt=".$award-\>name." /\>\<br\>".$award-\>name." \</td\>"; $i++; } }
This will show a message that the pilot has no awards yet instead.
