value not getting passed thru eval()

[spookie]

Hi,

I am using this code,

eval($_SESSION["product"]->GetTemplate($_GET["ID"]));

but the value is not getting passed to the called function.
The value of $_GET["ID"] is set.

Thanks in advance

for an eval statement to work, you must pass an argument that resolves into a string with complete php syntax. so your code might look more like this:

eval("$_SESSION['product']->GetTemplate($_GET['ID']);");

i dont know if this will work, but do take note of the added semicolon at the end of the line of code, as well as the added quote marks so that it is a string.

if that does not work, you can try something like this:

$s_product = $_SESSION['product'];
$get_template = "GetTemplate(" . $_GET['ID'] . ")";

eval($s_product . "->" . $get_template . ";");

this method uses explicit string concatenation, and builds the actual string content outside of the function call.

if you read the eval() section of the php manual at

http://www.php.net/manual/en/

then i think you would find your answer.

I tried both the ways but both are giving me parse errors.

Thes second one gives me:
parse error, unexpected T_OBJECT_OPERATOR in filename...

What is it that you are trying to do? Does the

GetTemplate

function return a string to be

eval

'ed?

GetTemplate calls another function .
The functions are as follows,

function GetTemplate($id)
  {
	  $this->Template = new template ; 	  
	  return $this->Template->GetFrameSet1($id);	   
  }

  function GetFrameSet1($id)
  {
	
    if(!isset($this->FrameSet))
    {
	  $db = new DB;
	 
	
	 $sql = "select frameset from eb_template where template_id = $id";   	 
	     
      $db->query($sql);
      $db->next_record();
      $this->FrameSet = $db->f("frameset");
    }    
    return $this->FrameSet;
  }

Any ideas ?

You are using too many functions that I don't know what they return for me to figure out what

GetTemplate

returns. If you print the return, does it print PHP statements?
