Invalid arguement, help

[1josh13]

Hey again guys,

 

I get the following error "Warning: Invalid argument supplied for foreach() in /home/evewebsp/public_html/v2/api/index.php on line 145"

 

The code is: (from lines 143 to 167)

 

<?php
if(!count($keys) < 1){
foreach($userChars as $key => $value){
		switch($value["info"]["skilllevel"]){
			case 0:
				$value["info"]["skilllevel"] = $value["info"]["skilllevel"];
			break;
			case 1:
				$value["info"]["skilllevel"] = "I";
			break;
			case 2:
				$value["info"]["skilllevel"] = "II";
			break;
			case 3:
				$value["info"]["skilllevel"] = "III";
			break;
			case 4:
				$value["info"]["skilllevel"] = "IV";
			break;
			case 5:
				$value["info"]["skilllevel"] = "V";
			break;
			default:
				$value["info"]["skilllevel"] = "unknown";								
		}

It's because $userChars isn't an array, which makes it an invalid argument for foreach that expects an array.

[1josh13]

so hw would I edit it to make it an array? or just to work?

[Daniel0]

Just check if it's an array and don't run the loop if it isn't.

[1josh13]

So the code to find if its array would be:??

 

<?php
$yes = array('$userChars');

echo is_array($yes) ? 'Array' : 'not an Array';
echo "\n";

$no = 'this is a string';

echo is_array($no) ? 'Array' : 'not an Array';
?>

 

Correct?

 

If so then I get "not an array", where do I go from here?

[Daniel0]

Well, more like:

 

if (is_array($userChars)) {
// foreach loop here
}

[wildteen88]

Where and how is the $userChars variable being set?

[1josh13]

Where and how is the $userChars variable being set?

 

TBH, a friend gave me this code, so I wouldnt know where exactly to look,

 

 

And with the arrays, i dont think i got it working

 

EDIT:

 

I believe that i have found where the $userChars variable is being set:

 

<?php
$userChars = array();

$sql = "SELECT * FROM `api_chardetails` WHERE `characterID` = '".$characterID."'";
$userdata = $dbc->Query($sql);
$userChars[$characterID]["details"] = mysql_fetch_assoc($userdata);

$sql = "SELECT * FROM `api_chars` WHERE `characterID` = '".$characterID."'";
$userDetails = $dbc->Query($sql);
$userChars[$characterID]["info"] = mysql_fetch_assoc($userDetails);

$sql = "SELECT * FROM `api_charsheet` WHERE `characterID` = '".$characterID."'";
$userskills = $dbc->Query($sql);
while($userSkillTemp = mysql_fetch_assoc($userskills)){	
	$index = count($userSkill);	
	$userSkill[$index] = $userSkillTemp;
}	

$userChars[$characterID]["skills"] = $userSkill;

foreach($userChars[$characterID]["skills"] as $key => $value){
	$index = count($skills);
	$skills[$index]["skillgroup"] = $api->GetGroupID($value['typeID'], $dataBase);
	$skills[$index]["skillname"] = $api->GetTypeName($value['typeID'], $dataBase);
	$skills[$index]["skillpoints"] = $value['skillpoints'];
	$skills[$index]["skilllevel"] = $value['level'];
	$skillpoints = $skillpoints + $value['skillpoints'];

}

sort($skills);
foreach($skills as $key => $value){
	if($value["skillgroup"] == 267){
