Block Help Please

Code:

<?php
if (eregi("block-Pages.php",$PHP_SELF)) {
Header("Location: index.php");
die();
}

function directory($result)
{
$handle=opendir("./users");
while ($file = readdir($handle)) {
if ($file == "." || $file == ".." || $file== "_notes" || $file== "htmlarea" || $file== "index.php") { } else { print "<a href=users/$file>$file</a> \n"; }
}
closedir($handle);

return $result;
}
$content .= "Select the users home page:";
echo directory($result);
?>

Works, but the result is shown above Block Title, not in actual Block.
Any advice or help gratefully received . TIA

You can't echo in a block. All output of a block must be handled through the $content variable. Try something like $content .= directory($result);

I also notice that you are passing a value ($result) to the function but their is nor $result in the block code outside of the function. Could just be that you don't have all the code. Just an observation Smile

Thanks Raven, I've obviously not coded correctly.Am trying to list folders that reside in a directory on server, and the blocks gives links to those folder. When clicked, the user should be taken to index.html file in each of the folders, depending on which link clicked. Any advice here on how I go about this please? TIA

I haven't tested this, but you might try

Code:

<?php
if (eregi("block-Pages.php",$PHP_SELF)) {
Header("Location: index.php");
die();
}

function directory()
{
global $content;
$handle=opendir("./users");
while ($file = readdir($handle)) {
if ($file == "." || $file == ".." || $file== "_notes" || $file== "htmlarea" || $file== "index.php") { } else { $content .= "<a href=users/$file>$file</a> \n"; }
}
closedir($handle);
}
$content = "Select the users home page: ".$content;
?>

Raven, regret no joy, but thank you very much for trying. Wink

Are you sure the fucntion is working correctly? Try inserting
echo $content;
after the closedir($handle); statement and see if it prints anything above the block. If not, then the function is not working.

My original coding produces the desired result, BUT it prints the link/s ABOVE the Block title, and not in the actual block, so am assuming that function code is working correctly, just that my code is putting it outside the actual block Confused

But, I need you to try what I suggested to help me in debugging it. Thanks.

Understood.

Code:

<?php
if (eregi("block-Pages.php",$PHP_SELF)) {
Header("Location: index.php");
die();
}

function directory($result)
{
$handle=opendir("./users");
while ($file = readdir($handle)) {
if ($file == "." || $file == ".." || $file== "_notes" || $file== "htmlarea" || $file== "index.php") { } else { print "<a href=users/$file>$file</a> \n"; }
}
closedir($handle);
echo $content;
return $result;
}
$content .= "Select the users home page:";
$content .= directory($result);
?>

Produces...
Link
Link
Then: Block Title(PAGES)
Then: Select the users home page:

First, a question. Did you use the global $content statment in my code I told you to try up above?

Code:

<?php
if (eregi("block-Pages.php",$PHP_SELF)) {
Header("Location: index.php");
die();
}

function directory()
{
global $content;
$handle=opendir("./users");
while ($file = readdir($handle)) {
if ($file == "." || $file == ".." || $file== "_notes" || $file== "htmlarea" || $file== "index.php") { } else { $content .= "<a href=users/$file>$file</a> \n"; }
}
closedir($handle);
}
$content = "Select the users home page: ".$content;
?>

If that doesn't work, then this should

Code:

<?php
if (eregi("block-Pages.php",$PHP_SELF)) {
Header("Location: index.php");
die();
}

function directory($result)
{
$content = "";
$handle=opendir("./users");
while ($file = readdir($handle)) {
if ($file == "." || $file == ".." || $file== "_notes" || $file== "htmlarea" || $file== "index.php") { } else { $content .= "<a href=\"users/$file\">$file</a> \n"; }
}
closedir($handle);
return $content;
}
$content .= "Select the users home page: ";
$content .= directory($result);
?>
