well here is a example:

$var1 += $var2

now this is using the +=

this is what it would look like but do the same thing with out the +=

$var1 = $var1 + $var2

ok.. i understand.. then the code will not work the way i put it..
it will look for 89.gif instead of 8.gif 9.gif

what is the solution?
thanks for your help.

I just ran that little code snippet. It does create a string with 8.gif and 9.gif.

Don't touch that part of the code. Create the images string after the loop, not inside.

TECK	04-17-2002 07:23 AM

so it will look like?

PHP Code:


		
			
if ($getchildforum[parentid]==$forumid) {

  $threadcount+=$getchildforum[threadcount];

}

$threadcountimage='<img src="'.implode('.gif"><img src="',preg_split('//',(string) $threadcount+,-1,PREG_SPLIT_NO_EMPTY)).'.gif">';

let me know if it correct. thanks.

TECK	04-17-2002 07:28 AM

nope.. is better this way:

PHP Code:


		
			
    $forumslist.=",$getchildforum[forumid]";

  }

  $DB_site->free_result($getchildforums);

  $threadcountimage='<img src="'.implode('.gif"><img src="',preg_split('//',(string) $threadcount+,-1,PREG_SPLIT_NO_EMPTY)).'.gif">';

am i correct?

TECK	04-17-2002 07:51 AM

nope. not working.. getting parse errors all over the place. :(
i tried also single quoted.. same result.

TECK	04-17-2002 08:09 AM

ok.. i think i got it:

PHP Code:


		
			
$forumslist.=",$getchildforum[forumid]";

}

$DB_site->free_result($getchildforums);

$threadcountimage='<img src="'.implode('.gif"><img src="',preg_split('//',(string) $threadcount,-1,PREG_SPLIT_NO_EMPTY)).'.gif">';

i forgot about the +, there is no need to have it there.. thanks alot ZZed.
i will let you all know tomorrow if it worked. ;)

Create a function to do that stuff... i.e:

Code:

function num2img ($number, $path = '') {

        return '<img src="' . implode('.gif"><img src="', preg_split('//', (string) $number, -1, PREG_SPLIT_NO_EMPTY)).' . gif">';

}

Stick that in functions.php and then just use it like this:

Code:

$threadcountimage = num2img($threadcount);

thanks alot firefly. :)
excellent idea the function.

btw, i'm trying the "answer through email"... ;)
