avatar system
anyone know how to make an avatar system for jp's script? like have it appear when you log in and on your user info and where it shows when your online? maybe a gallery/album feature to go along with it?

Re: avatar system
have you checked out ImageMagick or the GD libraries? Im pretty sure they are both capable of doing this. if you are not too comfortable with PHP's libraries i saw this short script from sitepoint here. Its definitely not the most powerful of images resizing scripts, but it can get the job done.

Re: avatar system
the thing with the sitepoint script is that it just tells the html what width and height it should display an image. this means if youve got a 1600 x 1280 image your browser will load the whole image, and then resize. This can mean slow load times...
Of course you shouldnt run into this problem cause you check to make sure the image is less than 15KB, but i figured id just let you know anyway.
Anyway, on to your question. You may want to consider putting the function in session.php because that page is included in all other pages (like userinfo.php). now for resizing the image, locate the snippet bustya gave us and edit it like this:
this will resize a users avatar as well as your no_avatar.gif file. Im assuming you read the sitepoint script and know how it works so dont forget to change your target to find the results youre looking for.
let me know how this works for you.

if(strcmp($database->username,$req_user_info['avatar']) == 0){
$mysock = getimagesize("include/userimg/no_avatar.gif");
echo '<img src="include/userimg/no_avatar.gif" ' . imageResize($mysock[0], $mysock[1], 150) . '/>';
}
else{
$mysock = getimagesize("include/userimg/" . $req_user_info['avatar']);
echo '<img src="include/userimg/'.$req_user_info['avatar'].'" ' . imageResize($mysock[0], $mysock[1], 150) . '/>';
}
this will resize a users avatar as well as your no_avatar.gif file. Im assuming you read the sitepoint script and know how it works so dont forget to change your target to find the results youre looking for.

Re: avatar system
i replaced the code with the one you gave me and i get this when i go to userinfo.php
Fatal error: Call to undefined function imageresize() in /home/vol11/xtreemhost.com/xth_4280991/htdocs/userinfo.php on line 49
i know i have to do more with it just dont know what, and i'm not sure what to change the target to either .

Re: avatar system
Well first off target is entirely up to you. Experiment with some values till you get what you want. The error you are getting is cause your script can't find the function you are calling. Did you put it in session.php? Can you post where you put it? If you put it somewhere else you have to make sure you include it in userunfo.php.

Re: avatar system
alright, but the actual function from sitepoint, did you add that into your code anywhere? thats why you get that error, because your script cant find the function.

Re: avatar system
you add this to session.php right? if i do, do i have to change anything in this code?
- Code:
function imageResize($width, $height, $target) {
//takes the larger size of the width and height and applies the
formula accordingly...this is so this script will work
dynamically with any size image
if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}
//gets the new value and applies the percentage, then rounds the value
$width = round($width * $percentage);
$height = round($height * $percentage);
//returns the new sizes in html image tag format...this is so you
can plug this function inside an image tag and just get the
return "width=\"$width\" height=\"$height\"";
}

Re: avatar system
you can really add the function to where ever you want. I just chose session because every page in your site would most likely be including session.php. that means which ever pages are including session.php can also use your image resizing function.
where ever you choose to add the function, you shouldnt need to change anything inside of it.

Re: avatar system
reason why i asked if i should change anything because no matter what way i add it i get this: Parse error: syntax error, unexpected T_STRING in /home/vol11/xtreemhost.com/xth_4280991/htdocs/include/session.php on line 494
i added it where it says "//img resize"

Re: avatar system
thats very odd. My first instinct is that because there arent any strings in this function this has something to do with the comments inside of the function. try putting the comments in a different type of comment syntax like this:
- Code:
/* img resize */
function imageResize($width, $height, $target) {
/* takes the larger size of the width and height and applies the
formula accordingly...this is so this script will work
dynamically with any size image */
if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}
/* gets the new value and applies the percentage, then rounds the value */
$width = round($width * $percentage);
$height = round($height * $percentage);
/* returns the new sizes in html image tag format...this is so you
can plug this function inside an image tag and just get the */
return "width=\"$width\" height=\"$height\"";
}

Re: avatar system
i think it was the comments because the page changed after i added that but now i get this again Fatal error: Call to undefined function imageresize() in /home/vol11/xtreemhost.com/xth_4280991/htdocs/userinfo.php on line 49.

Re: avatar system
alright so we're getting closer.
functions are case sensitive. in the code we call the function imageResize and the error you pasted says imageresize so see if that is our problem.

Re: avatar system
in the error the 'r' is lowercase but when i check where the error is its uppercase. should all the "r's" in "imageresize" be lower case or uppercase?

Re: avatar system
when you call a function you have to call it by EXACTLY what it is named. Our function is named imageResize so when we call it it has to be exact.
In other words you can change the name of the function and give it a small r or you put a capital R where you call the function, it doesnt matter just as long as the function name and call are exactly the same.

Re: avatar system
hmm, thats odd. try changing the name of the function to something a little more simple like "resize" (all lowercase without the quotes). Once you've changed the name of the function in session.php dont forget to change your function call to exactly what you renamed the function, and dont forget to check the case to make sure it matches.

Re: avatar system
alright so ive been at it just over an hour now and i cant re-create the error you've described with the code you've given me. but i do see you are including some kind of functions script inside of session.php. maybe try removing the sitepoint function from session.php and putting it inside your function script.
let me know what that does.

Re: avatar system
HUGE thanks that did the trick. i finally got it working. i actually tried that before but i forgot to try it again after i fixed the comments in it. now how do you make the image appear on another page? i tried using the code you put in your userinfo.php
but it only calls the no_avatar.gif.
- Code:
/* Avatar (assumes you have a default for folks who don't upload an avatar, here it is called "no_avatar.gif")*/
if(strcmp($database->username,$req_user_info['avatar']) == 0){
$mysock = getimagesize("include/userimg/no_avatar.gif");
echo '<img src="include/userimg/no_avatar.gif" ' . resize($mysock[0], $mysock[1], 150) . '/>';
}
else{
$mysock = getimagesize("include/userimg/" . $req_user_info['avatar']);
echo '<img src="include/userimg/'.$req_user_info['avatar'].'" ' . resize($mysock[0], $mysock[1], 150) . '/>';
}
but it only calls the no_avatar.gif.

Re: avatar system
well on any other page you probably arent running a query to make $req_user_info a valid array so i would mimic the way userinfo.php does it. first you would have to pass the username to the URL so we can call it in a function later. then, on whatever page you want to display the image, somewhere near the top, try putting:
that will create the $req_user_info array and then you can just put the same code as used in userinfo.php to display an avatar:
Now if you were thinking more like a member list page (like the one in this forum) where all usernames are displayed with their avatars beside them that may be a little trickier. Just off the top of my head i can see you needing to count the number of usernames in your database and using that as the limit in a for loop which more or less has the same code we just used before to display your image...
- Code:
/* Requested Username error checking */
$req_user = trim($_GET['user']);
if(!$req_user || strlen($req_user) == 0 ||
!eregi("^([0-9a-z])+$", $req_user) ||
!$database->usernameTaken($req_user)){
die("Username not registered");
}
/* Display requested user information */
$req_user_info = $database->getUserInfo($req_user);
that will create the $req_user_info array and then you can just put the same code as used in userinfo.php to display an avatar:
- Code:
/* Avatar (assumes you have a default for folks who don't upload an avatar, here it is called "no_avatar.gif")*/
if(strcmp($database->username,$req_user_info['avatar']) == 0){
$mysock = getimagesize("include/userimg/no_avatar.gif");
echo '<img src="include/userimg/no_avatar.gif" ' . resize($mysock[0], $mysock[1], 150) . '/>';
}
else{
$mysock = getimagesize("include/userimg/" . $req_user_info['avatar']);
echo '<img src="include/userimg/'.$req_user_info['avatar'].'" ' . resize($mysock[0], $mysock[1], 150) . '/>';
}
