Invalid argument

[daveoliveruk]

I have the following piece of code:

 

 

foreach($classRequests as $key => $val) {

 

if(is_array($val)){

foreach ($val as $key2 => $val2) {

if ($key2 == "UserID")

$strIDs2 = add2string($strIDs2, $val2, ',');

if ($key2 == "RequestedUserID")

$strIDs2 = add2string($strIDs2, $val2, ',');

}

} 

else {

if ($key == "UserID")

$strIDs2 = add2string($strIDs2, $val, ',');

if ($key == "RequestedUserID")

$strIDs2 = add2string($strIDs2, $val, ',');

}

 

 

 

}

 

And in the logs I'm getting:

 

[Tue Feb  5 11:57:36 2008] [error] PHP Warning:  Invalid argument

supplied for foreach() in /home/public_html/menu_home.php on

line 589

 

Is tehre anyway to avoid this?

 

Thanks in advance!

What is $classRequests ?

[haku]

If its the result of a mysql query, you need to extract the arrays from it (mysql_fetch_array() or mysql_fetch_assoc()) before you can use it in the foreach loop.

[daveoliveruk]

$classRequests is an array returned from an API

[revraz]

print_r($classRequests);

 

And post what it contains.

And I assume

foreach($classRequests as $key => $val) {

is line 589?

[daveoliveruk]

No its if(is_array($val)).

 

When I check for an array.

[rhodesa]

can't be....it's gotta be

foreach($classRequests as $key => $val) {

or

foreach ($val as $key2 => $val2) {
