variation of FireFly's "Online Users" hack

1 Attachment(s)

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.

I think it has something to do with png file types. I dont know much about it except that you can have scripts in php place a value over an image.

*shrug* its a start.

flash can also be updated dynamically .. so that might be another option for you ...

TECK	04-11-2002 06:18 AM

unfortunatelly, the font is extremly small. in flash, it will be invisible. the only way i see it is by using the little digits i made. it should be a way to call and replace them individually, using if arguments. i honestly dont know how to do it. help is apreciated. thanks.

Here's one way to do that. $number holds the number you want to turn into images:

PHP Code:


		
			
$number = 123;

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

(the preg_split() call is taken from PHP's manual)
For that number you'll get this output:

Code:

<img src="1.gif"><img src="2.gif"><img src="3.gif">

i'm the happiest guy in the world.. you saved me a ton of work firefly!!!!! thank you so much!!!
i will try it tonight....

TECK	04-11-2002 04:42 PM

so i can use this function with basically every numbers listed in VB, like for example posts/threads right?

Admin

Yup.

TECK	04-11-2002 09:10 PM

thanks for the the help, firefly.

TECK	04-17-2002 05:41 AM

ok, now firefly(or any experienced hacker)... i have another prob... when i try to replace the number of threads in forumhome, i get stuck. here's what i did:
i opened functions.php and located the $threadcount. then i got amased with the + in there:

Code:

$threadcount[high]+[/high]=$getchildforum[threadcount];

if it wouldnt be that +, i would do this:

PHP Code:


		
			
$threadcount=$getchildforum[threadcount];

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

can i do this?

PHP Code:


		
			
$threadcount+=$getchildforum[threadcount];

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

can you explain to me please what the + do?
thanks alot.

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

TECK	04-17-2002 05:52 AM

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.

Zzed	04-17-2002 07:54 AM

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

Admin

04-17-2002 07:59 AM

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

TECK	04-17-2002 08:23 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 08:28 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 08:51 AM

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

TECK	04-17-2002 09:09 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);

TECK	04-17-2002 04:59 PM

thanks alot firefly. :)
excellent idea the function.

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

Cool Hack idea nakkid...

I suppose if you like having all those number pictures, its ok...Doesnt it take longer to load the images than just text?

TECK	04-17-2002 08:28 PM
