Class troubles, I am sooooo desperate!

dlumley

Hi,

Perhaps you can help before I take a hammer to my pc! I am trying to modify a template class to accept a path input for includes files I almost have it working, here is the problem...

If I declare the path explicitly in the class like this:

var inc_path = "/templates/";

It works, but if I declare the inc_path variable as:

var inc_path;

Then set it externally like this...

mytemplateobj->inc_path = "/templates/";

It does not work! I have set up a few temporary functions to make sure that the variable is being "seen" within the class and it is!!! But the function that I am trying to parse the variable to refuses [Note that word refuses!!!] to "see" the variable

I am going nuts and have spent over 3 hours trying to sort out the problem. I can't understand why it works if I explicitly declare the variable but not if I externally declare it! Inconceivable!!!

I am not going to include all the code... just the bits that will give an idea....

class blah
{
var $inc_path;

/This function works when I set the variable externally and does indeed echo the variable..../

function dwanetest()
{
echo "<hr>THis is my TEst -- - " . $this->inc_path . "$blah <hr>";
}

// Using a function to set the path does not work either...
function set_path($the_path)
{
$this->inc_path = $the_path;
}

/This function does not work unless I set the variable within the class file above
as follows:
var $inc_file = "/templates/" ;
*/

function r_getfile($file) {

echo "<hr>debug test....." . $this->inc_path . "<hr>";
//die;
$text=$this->getfile($file);
while (preg_match($this->file_delim,$text,$res)) {
echo $this->inc_path;
$text2=$this->getfile($this->inc_path . $res[1]);
$text=preg_replace("'".preg_quote($res[0])."'",$text2,$text);
}

return $text;

}

Not even the echo of the variable works...here is my code calling the class...

$templateObj = New XTemplate ($maintemplatedir . "/main.htm");
$templateObj->inc_path = "/Templates/";

I have even tried to set the path with a function but get the same result..
//$templateObj->set_path();

$templateObj->dwanetest();

Your help may save the life of a computer.

Thanks.

$text2=$this->getfile($this->inc_path . $res[1]); 
//mabye if you change it to 
$text2=$this->getfile("$this->inc_path" . $res[1]); 
//it will work (note quotes)

I think you need a constructor in your class to initialize the property and make it local:

class foo
{

   // define property
   var $inc_path;

   // Constructor Method
   function foo()
   {
      // initialize property
      $this->inc_path = "";
   }

   // other class methods here

}

Then you can set the property with either a set property method (the right way) or directly.

The constructor did it... the class already had one, I modified it and viola it now works!!

If anyone is looking for a template system to work with dynamic inlclude paths then I have it. I am usin Xtemplate by the way and will post the patch [or hack] up on source forge. Or just contact me and I will send it to you.

Thanks for your responses!
