[topflight]

I am reccevie the following error:

Warning: Invalid argument supplied for foreach() in /home/mysite/public_html/mypage.php on line 22

 

 

<?php
require_once("VatsimPHPgenerator.php");
$VatsimPHP=new VatsimPHP;
?> 

<?php
$clientlist=$VatsimPHP->pilots();
?> 

<?php
$clientlist=$VatsimPHP->airline(array("ASA", "QXE"));
?>


<table width="100%" bgcolor="#DDDDDD">
<tr><td colspan=4 align=center bgcolor=#EEEEEE>No People Online</td>
</tr>



<table width="100%" cellpadding="0" align="left" bgcolor="#dddddd" >
<? foreach($clientlist as $client)
    { 
    echo"<tr>";
        echo"<td colspan=4 bgcolor=#EEEEEEalign=center>".$client[2]."</td>";
        echo"<td colspan=4 bgcolor=#EEEEEEalign=center>".$client[0]."</td>";     
        echo"</tr>";
      
    }
        ?>                                                                               
    </table>

 

This is line 22:

<?php foreach($clientlist as $client) ?>

 

Thanks in advanced.

Can we see the airline() function?  It should return an array.

I am confused what do you mean. This is a 3rd Party Script

Hmm that's weird.  Be careful, it may just be for a specific case you just tested with or something.  But you're welcome, lol.

Well I am basically getting information from a source online and I notice when I put a different airline prefix in, it worked because there are like a lot airline connected to that network. But I do want to know how can I count that information for instance if it =0 then say nobody is online, so I wont receive that error.

If what you mean is when the '$clientlist' is 0 then don't display the table, then you could do:

 

</pre>
<table width="100%" cellpadding="0" align="left" bgcolor="#dddddd">

if(count($clientlist) == 0)
{
   foreach($clientlist as $client)
   {
      echo "";
      echo "" . $client[2] . "";
      echo "" . $client[0] . "";     
      echo "";
     
    }
   else
   {
      echo "";
      echo "Sorry, no clients.";
      echo "";
   }
}
?>                                                                               

</

 

NOTE - Never use short tags, always use '<?php', to increase portability.

Well if equal zero it is still going to run that, I want it to have it setup so that if it does equal zero it will say the no clients online else if it doesn't it will run the script how can I do that?

if(count($clientlist) != 0)
