variation of FireFly's "Online Users" hack

i want to change this hack to make it use images instead of numbers. an easy way to do would be to make one zillion gif files named 1.gif, 2.gif.... 894.gif. however, a much more elegant solution would be to create all the digits individually, then have them replace the actual values. so if i have 89 members online the 2 digits will be replaced by 8.gif and 9.gif.

i'm not sure what is the exact aproach on this. can you spare few minutes of your time and give me a solution?
please, post a code example in this thread.

i attached a picture, so you see actually what i try to achieve.
thanks for taking the time to help me solve this problem.

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]

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]

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]

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

[TECK]

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.

[Admin]

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

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:

$threadcountimage = num2img($threadcount);

[TECK]

thanks alot firefly.
excellent idea the function.

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