$this->load->helper('myhelper');

in myhelper.php file

Code:
// if blank string returns 1

function is_blank($str){

    $temp=str_replace("\n","",$str);

    $check=0;

    for($i=0;$i<strlen($temp);$i++) 

    {

     if($temp[$i]=="<") $check=1;

     if(!$check) $temp2.=$temp[$i]; 

     if($temp[$i]==">") $check=0;

    }

    if(eregi("[^[:space:]]",$temp2)) return 0;

    return 1;

}

when I try to this my own helper function CI displays error as belows..

Code:
Message: Undefined variable: temp

temp, temp2 is not param which is defined function name parameter..

What is wrong????

try this instead

Code:
function is_blank($str){

    $temp=str_replace("\n","",$str);

    $check=0;

    $temp2='';

    for($i=0;$i<strlen($temp);$i++)

    {

     if($temp[$i]=="<") $check=1;

     if(!$check) $temp2.=$temp[$i];

     if($temp[$i]==">") $check=0;

    }

    if(eregi("[^[:space:]]",$temp2)) return 0;

    return 1;

}
