Yes you are right, it is too much of a mess to even try to understand it.

However, the error is telling you that http://bla.bla./bla.img cannot be
found.

yes, I know that, but whay? Why in one line of code but not in the other line?

here is another, way shorter attempt,
(changed LF to CRLF, hope this will help):

<?php
function pict_size($path ) {
list($w,$h,$t,$ a) = getimagesize($p ath);
$size=" width=" . ceil($w/2) . " height=" . ceil($h/2) . " ";
return $size;
}
function bbcode_format($ newtxt) {
$newtxt = stripslashes($n ewtxt);
$bbkod = array(
'/\[b\](.*?)\[\/b\]/is',
'/\[i\](.*?)\[\/i\]/is',
'/\[url\=(.*?)=url\](.*?)\[\/url\]/is',
'/\[img=(.*?)\ img\]/is',
'/\r\n/is');
$htmlkod = array(
'<b>$1</b>',
'<i>$1</i>',
'<a href="$1">$2</a>',
'</p><img src="$1" /><p>',
'</p><p>');
$newtxt = preg_replace($b bkod, $htmlkod, $newtxt);
preg_match_all( '/src=(.*?) \/>/i', $newtxt, $matches, PREG_SET_ORDER) ;
$i=0; // probably not needed, but makes me sure
foreach ($matches as $val) {
$i++;
$path = trim($val[1]);
$nums = pict_size($path );
$all = $val[1] . "$nums";
$base[$i]=$val[1];
ksort($base);
$new[$i]=$all;
ksort($new);
}
$newtxt = str_replace($ba se, $new, $newtxt);
return $newtxt;
}
if($_POST['tekst']) {
$tekst = $_POST['tekst'];
$tekst = strip_tags($tek st);
$tekst = htmlspecialchar s($tekst, ENT_QUOTES);
if (!get_magic_quo tes_gpc()) {
$tekst = addslashes($tek st);
} else {
$tekst = $tekst;
}
echo"what we can get from mysql query one day:<br>$tekst< br>";
$prikaz = bbcode_format($ tekst);
echo"$prikaz";}
else {
?>
<form action="<?= $PHP_SELF; ?>" method="post">
<textarea name="tekst" id="tekst" rows="5" cols="60">
[img=http://nastamba.net/kalnik.jpg img]
</textarea>
<br>
<input type="submit" />
</form>
<?php
}
echo"line to test getimagesize() alone with :".
"list(\$w,\$h,\ $t,\$a) =
getimagesize('h ttp://nastamba.net/kalnik.jpg');<b r>";
list($w,$h,$t,$ a) = getimagesize(tr im('http://nastamba.net/kalnik.jpg'));
echo"<img src='http://nastamba.net/kalnik.jpg' $a />";?>

Re: getimagesize() working and *not*working... why?

OK, this time it was almoast perfect copy-paste :)

so, the following line (#3) "isnt working"

list($w,$h,$t,$ a) = getimagesize($p ath);

I'm calling it in function starting at line #7

function bbcode_format($ newtxt) {

in line #27

$nums = pict_size($path );

which itself is called after submit button action in line #47

$prikaz = bbcode_format($ tekst);

but(!), the "same" function on line 63 is working with the very same picture!

list($w,$h,$t,$ a) = getimagesize(tr im('http://nastamba.net/kalnik.jpg'));

why is that?

Probably because the filename you're passing is not what you expect.
Try echoing the filename from your bbcode_format() function.

Also, why are you using addslashes()? If you're on a good server,
magic_quotes_gp c() should be off, so you shouldn't need to check it.
But if you do need to check it, all you should have to do is call
stripslashes() if it's on.

yes - that was a problem. just checked minute ago echoing in the function
pict_size() and I'w got $path with quotes from line 19 in bbcode_format
function: '</p><img src="$1" /><p>', stupid and bizare mistake... :)

magic_quotes_gp c() should be off, so you shouldn't need to check it.

akhm, khm... well, I'll check on that - I'm not programer, just photographer
who decided to use php to develop and maintain one (10 years old! :)) photo
comunity.

tnx for support once again :D

You are a programmer, whether an amateur or professional.

But you really need to understand what's going on. Things like SQL
injection, quite easy to do if you don't add the appropriate safeguards,
can be quite damaging to your site, your reputation and even possibly
your customers.
