Hello,

I have a php file like the following:
<?php foreach($res as $album) { ?>
<div class="albums">
<div class="left albumimage">
<a href="album/<?php echo $album["id"] ;?>">
<img alt="<?php echo $album["title"]; ?>" title="<?php echo
$album["title"]; ?>" src="<?php echo "../".$photosdir.$album["photo"]; ?>">
</a>
</div>
<?php } ?>

I call this file from a function :
function ListAlbums($res) {
include('views/albums_view.php');
}

Before this I have opened a sql query and $res has the resultset. So my
pages renders correctlly for each of the rows on $res.

But now I want for this file not to be printed directly (as include
does) but rather store the output to a string. As I read at
http://us3.php.net/include/ I did:

function ListAlbums($res) {
ob_start();
include('views/albums_view.php');
$disp=ob_get_contents();
ob_end_clean();
return $disp;
}

But $res now seems to be empty. Why doesn't this approach work? If I
print_r($res) into my function it returns of course data.

thanks

The reason it is not working is because you are not passing the $res
variable to the function.

function ListAlbums($result_set) {
ob_start();
include('views/albums_view.php');
$disp=ob_get_contents();
ob_end_clean();
return $disp;
}

You will now need to call that function:

ListAlbums($res);


That aside, why pass it if you don't seem to be using it in the
function anyway?

Nvm on that last question wasn't paying attention to the include.

I'm not sure why it shouldn't work. However, there is a better way to
do this.

First of all, the code in your included file should itself be a
function. Then, rather than outputting the html right there, put it
into a string, and return the string, i.e.

<?php
function myfunc($res, $photosdir) {
$str = '';
foreach($res as $album) {
$str .= <<<EOT
<div class="albums">
<div class="left albumimage">
<a href="album/{$album["id"]}">
<img alt="{$album["title"]}" title="{$album["title"]}"
src="../{$photosdir}{$album["photo"]}">
</a>
</div>
EOT;
}
return $str;
}


Now in the calling routine you have the option of echoing the string or
not, i.e.

echo $myfunc($res, $photosdir);
or

$str = $myfunc($res, $photosdir);

You can now include the file at the top of your page and call it from
where ever you need it.
