Problem with RSS2: multiple rss in the same page
 
Hello, I'm using this code:

http://www.vbulletin.com/forum/showt...g-an-RSS2-feed

If I try to use it twice, I get this error:

Quote:
Fatal error: Cannot redeclare character_data() (previously declared in C:\Programmi\EasyPHP 3.0\www\**\**\**\a.php:25) in C:\Programmi\EasyPHP 3.0\www\**\**\**\b.php on line 53
Can you please help me? :)

No one can help me?

Each block like

Code:
function something()
{
...
...
}
defines a function and so only needs to (and only can) appear in the same code once. So, if you're using that code twice in the same php file, just leave out the function definition blocks the second time.

Thank you, now it works! I have just one problem. In the second list, I get also the results of the first website. How can I solve this?

You need to include

$rss2_output = '';

before you use the code the second time.

Aaah I've been looking for this, I'm also on the same lines as Triky was with duplicating the results, not sure how to solve it even though you said that I need to include the output before re-using the code again.

What I have so far is this:
PHP Code:
<?php
$rss2_art_file = 'http://localhost:41648/forums/external.php?type=RSS2&forumids=8';
$rss2_games_file = 'http://localhost:41648/forums/external.php?type=RSS2&forumids=5';

$is_item = false;
$tag = '';
$title = '';
$description = '';
$link = '';
$date = '';
$author = '';

function character_data($parser, $data) {
    global $is_item, $tag, $title, $description, $link, $date, $author;
    
    if ($is_item) {
        switch ($tag) {
            case "TITLE":
                $title .= $data;
                break;
            case "DESCRIPTION":
                $description .= $data;
                break;
            case "LINK":
                $link .= $data;
                break;
            case "PUBDATE":
                $date .= $data;
                break;
            case "AUTHOR":
                $author .= $data;
                break;
        }
    }
}

function begin_element($parser, $name) {
    global $is_item, $tag;
    
    if ($is_item) {
        $tag = $name;
    } else if ($name == "ITEM") {
        $is_item = true;
    }
}

function end_element($parser, $name) {
    global $is_item, $title, $description, $link, $date, $author, $rss2_art, $rss2_games;
    
    if ($name == "ITEM") {
        $rss2_art .= "<b><a href='" . trim($link) . "'>" . htmlspecialchars(trim($title)) . "</a></b> - " . htmlspecialchars(trim($date)) . "<br>";
        $rss2_games .= "<b><a href='" . trim($link) . "'>" . htmlspecialchars(trim($title)) . "</a></b> - " . htmlspecialchars(trim($date)) . "<br>";
        $title = "";
        $description = "";
        $link = "";
        $date = "";
        $author = "";
        $is_item = false;
    }
}

$parser = xml_parser_create();

xml_set_element_handler($parser, "begin_element", "end_element");
xml_set_character_data_handler($parser, "character_data");
$fp_art = fopen($rss2_art_file,"r");
$fp_games = fopen($rss2_games_file,"r");

while ($data = fread($fp_art, 4096)) {
    xml_parse($parser, $data, feof($fp_art));
}
while ($data = fread($fp_games, 4096)) {
    xml_parse($parser, $data, feof($fp_games));
}

fclose($fp_art);
fclose($fp_games);
xml_parser_free($parser);
?>
That is in a separate file required once into the page and have it echoed out, but like Triky had, I have a duplicate.

Try this:

PHP Code:
<?php
$rss2_art_file = 'http://localhost:41648/forums/external.php?type=RSS2&forumids=8';
$rss2_games_file = 'http://localhost:41648/forums/external.php?type=RSS2&forumids=5';

$is_item = false;
$tag = '';
$title = '';
$description = '';
$link = '';
$date = '';
$author = '';

function character_data($parser, $data) {
    global $is_item, $tag, $title, $description, $link, $date, $author;
    
    if ($is_item) {
        switch ($tag) {
            case "TITLE":
                $title .= $data;
                break;
            case "DESCRIPTION":
                $description .= $data;
                break;
            case "LINK":
                $link .= $data;
                break;
            case "PUBDATE":
                $date .= $data;
                break;
            case "AUTHOR":
                $author .= $data;
                break;
        }
    }
}

function begin_element($parser, $name) {
    global $is_item, $tag;
    
    if ($is_item) {
        $tag = $name;
    } else if ($name == "ITEM") {
        $is_item = true;
    }
}

function end_element($parser, $name) {
    global $is_item, $title, $description, $link, $date, $author, $rss2_output;
    
    if ($name == "ITEM") {
        $rss2_output .= "<b><a href='" . trim($link) . "'>" . htmlspecialchars(trim($title)) . "</a></b> - " . htmlspecialchars(trim($date)) . "<br>";
        $title = "";
        $description = "";
        $link = "";
        $date = "";
        $author = "";
        $is_item = false;
    }
}

$parser = xml_parser_create();

xml_set_element_handler($parser, "begin_element", "end_element");
xml_set_character_data_handler($parser, "character_data");
$fp_art = fopen($rss2_art_file,"r");
$fp_games = fopen($rss2_games_file,"r");

$rss2_output = '';
while ($data = fread($fp_art, 4096)) {
    xml_parse($parser, $data, feof($fp_art));
}
$rss2_art = $rss2_output;
$rss2_output = '';
while ($data = fread($fp_games, 4096)) {
    xml_parse($parser, $data, feof($fp_games));
}
$rss2_games = $rss2_output;

fclose($fp_art);
fclose($fp_games);
xml_parser_free($parser);
?>

It would be better to put the code in a function where you pass the file name and return the string, but this should work.
