i got this code:

print "<a HREF=\".$row['sciezka'].\"><img SRC=\".$row['thumb'].\"><br>.$row['nazwa'].(.$row['ile'].)</A>"

and i get this error :

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in c:\foxserv\www\tapety\kategoria.php on line 10

what's wrong ?

i am not too good in php, but for myscript with uses array, i assign the array to a variable

$sciezka = $row['sciezka'];
$thumb = $row['thumb'] ;

i am not to sure will work or not.

[Domel]

or.. you can try this:

print "<a HREF=\".${row['sciezka']}.\"><img SRC=\".$row['thumb'].\"><br>.${row['nazwa']}.(.{$row['ile']}.)</A>"

Instead of all of that going in and out of quotes, just take the single quotes out. I am well aware of the possible complications from not using single quotes (with constants and such), but those do not apply when you are inside double quotes.

print "<a HREF=\"$row[sciezka]\"><img SRC=\"$row[thumb]\"><br>$row[nazwa]($row[ile])</A>"; 

I don't recommend this:

$nazwa = $row['nazwa'];

That's a newbie workaround and is not a good idea because first you are wasting time re-assigning a temporary variable, you are wasting space, and useless temp variables like that only set you up for more debugging and maintenance hassles down the road.

Are you pulling that from a DB? And is that inside a loop?
If so, you may want to think about using extract().

while ($row=mysql_fetch_array($result, MYSQL_ASSOC)) {
    extract($row);
    print "<a HREF=\"$sciezka\"><img SRC=\"$thumb\"><br>$nazwa($ile)</A>";
}

Max,

Still no reason to use extract(), that's just more unecessary temp variables...

[Mark Hensler]

not if you do something like this:

while (@extract(@mysql_fetch_array($result, MYSQL_ASSOC))) {

I sometimes throw project settings into a DB. Here is what the table looks like:

+----+-----------+-------------+--------+
| ID | var       | val         | define |
+----+-----------+-------------+--------+
|  1 | image_dir | /images     | false  |
|  2 | site_name | Sporkopolis | false  |
|  3 | BG_COLOR  | #FFFFFF     | true   |
+----+-----------+-------------+--------+

data types:
ID = int
var = varchar(255)
val = varchar(255)
define = enum('true','false')

And here is the code that makes my vars and constants:

$query = "SELECT * FROM table_name";
$result = mysql_query($query);
if (!$result) {
    Query_Error(__FILE__, __LINE__, $query);
    
    // set some default values:
    $image_dir = '/images';
    $site_name = 'Sporkopolis';
    define("BG_COLOR", "#FFFFFF");
    
}

while ($result && @extract(@mysql_fetch_array($result, MYSQL_ASSOC))) {
    
    if ($define=='true') {
        define($var, $val);
    }
    else {
        ${$var} = $val;
    }
    
}
