script error - Warning: Invalid argument supplied for foreach()

[ToiletDuck]

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>&nbsp;&nbsp;<img src=".$award->image." alt=".$award->name." /><br>".$award->name." &nbsp;&nbsp;</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>&nbsp;&nbsp;<img src=".$award->image." alt=".$award->name." /><br>".$award->name." &nbsp;&nbsp;</td>";
	 $i++;
 }
}
 

Try this code

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>&nbsp;&nbsp;<img src=".$award->image." alt=".$award->name." /><br>".$award->name." &nbsp;&nbsp;</td>";
				$i++;
			}
	}

This will show a message that the pilot has no awards yet instead.
