php array error in mysql query

[kalster]

when i run the below code i get an error...

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in...

but when i take out the h>0 then there is no errors in the code. in table users, i need all columns in the array. How to get h>0 working?

$query = "SELECT * FROM users WHERE h>0 ORDER BY id";
$result = mysqli_query($link, $query);

$data = array();
while($row1 = mysqli_fetch_array($result))
{
	$data[] = $row1;
} 

print_r($data);

i made a mistake about the error message. the error message is... Warning: array_push() expects parameter 1 to be array, null given in

 also, here is the function that gives the error.

function getAllParents($id,$ibp){ //full path

foreach($ibp as $parentID=>$nodes){ 

    foreach($nodes as $node){

        if($node['id']==$id){

             if($node['parentId']!=0){

                $a=getAllParents($node['parentId'],$ibp);
                array_push($a,$node['parentId']);
                return $a;

              }else{
                    return array();
                  }

             }
    }
}
}

i made a mistake about the error message.

Huh? How can you make a mistake? The two errors have two completely different meanings

 

 

 

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in...

This type of error usually indicates the query has failed. To find out why the query failed you need to use mysql_error

 

 

 

Warning: array_push() expects parameter 1 to be array, null given in

This means the variable you have given it as the first parameter is not an array.

I was trying to fix the error and had another error. i just mixed the error messages.

i fixed the error by giving a value of 1 instead of 0 in another function.
