    resolved [RESOLVED] Code PHP with MySQL info?

    Hi! I have the following code, but it is just not working.

    (I'm just showing the code snippets that I think are necessary, let me know if you need more)

    PHP Code:
    $hata "helmet1";

    $getfj mysql_query("select * from usr_function where func = '$hata' limit 1");
    $funcj mysql_fetch_array($getfj);
    imagecopymerge($skin,$hat,0,0,0,0,$hat_x,$hat_y,$funcj[op]);
    $funcj['ext1'];
    $funcj['ext2'];
    $funcj['ext3'];
    $funcj['ext4']; 
    And here's the MySQL info:
    id int(9):
    9

    func varchar(30):
    helmet1

    op varchar(3) :
    100

    ext1 varchar(50):
    $visor = imagecreatefromgif("hs/news/Upload/images/visor2.gif");

    ext2 varchar(50):
    $visor_x = imagesx($visor);

    ext3 varchar(50):
    $visor_y = imagesy($visor);

    ext4 varchar(50):
    imagecopymerge($skin,$visor,0,0,0,0,$visor_x,$visor_y,80);

    Can you define "not working"? Is there an error message, or what? Have you done the usual things like verifying that the call to mysql_query() did not return false, and if it did, seeing what mysql_error() says and echoing out the query string? If it's OK, did you verify that any matches were found in the DB via mysql_num_rows()?

    Also, what's up with the last 4 lines that don't actually do anything?

    I wonder if that is the problem? Maybe he is expecting output and not getting any. Surely it can't be that can it?

    Define 'not working' a bit more specifically.

    Start debugging your code, is it connecting to the db?
    Is it correctly saving results to a variable?

    Oh; I just realised what you're trying to do; you're storing PHP commands as a string variable, and trying to execute the command by putting the variable name...

    ...Yeah...Not the way to do it.

    What you want is this :

    Code:
    $hata = "helmet1";
    
    $getfj = mysql_query("select * from usr_function where func = '$hata' limit 1");
    $funcj = mysql_fetch_array($getfj);
    imagecopymerge($skin,$hat,0,0,0,0,$hat_x,$hat_y,$funcj["op"]);
    $visor = imagecreatefromgif($funcj["path"]);
    $visor_x = imagesx($visor);
    $visor_y = imagesy($visor);
    imagecopymerge($skin,$visor,0,0,0,0,$visor_x,$visor_y,80);
    And in the database, scrap ext1, ext2, ext3 and ext4; and replace them with one field: path (VARCHAR 50).

    Thanks! I modified your code to fit my needs and it works great.

    Sorry to the others - the 'not working' was the last 4 lines in my code.
