can someone tell me how to make this work? becuase if i put it in side the while it works, but it only loops the same file.

Code: Select all

<?
$path = "/Gallery/thumbs/";
$handle = opendir($path);
$row = 3;
$col = 3;

while(false !==($file = readdir($handle))){
if($file !="." && $file !=".."){
 continue;
}
closedir($handle)
}
     for($r=1;$r <= $row; $r++){
	 echo "<tr>";
 for($c=1; $c <= $col; $c++){
 echo "<td><img src=$path/$file[]></td>";
 }
 echo "</tr>";
}

?>

You don't need the for loops. What you do need is conditionals (if's) to know when and where to write out the table row ends.

Have a look at the first two threads referenced in Useful Posts.

thats the best i could come up with using the if , and it wont come out because i dont know ...i saw the other thread that i could do because is uusing the data base but i'm doing it while opening a directory..

Code: Select all

<table border="1">
<?
$path = "/Gallery/thumbs/";
$handle = opendir($path);
$row = 3;
$col = 3;

while(false !==($file = readdir($handle))){
if($file !="." && $file !=".."){
     if($r=1;$r <= $row; $r++){
	 echo "<tr>";
 if($c=1; $c <= $col; $c++){
 echo "<td><img src=$path/$file></td>";
 }
 echo "</tr>";
}
}
}

?>
</table>

Is "Gallery " the sub-folder of the current script directory ?

it is a sub foder the scrip is bene places on a the same level as the gallery folder so i need the /gallery to go inside of it.. but i don't see why is not displaying .. just shows [x] and if i make the pictures a <a href> it just takes me to the directory .

You are always outputting $filename... In a loop where only $c changes...

By reading (and understanding): http://be2.php.net/manual/en/control-structures.for.php

Probably you want to checkout the other control structures too.
