Show Thread Enhancements - Title Tag Fetcher (Auto Replace URL with Titletag)

Hi there.

Since I needed a new URL Autotext Generator, I always loved the prework of Jafo232 and his Replace URL's With Page Title.
I just did some modifications on this Mod and for some forseeing mistypings, I also leaned out the checking of the "www" if given.

For those who don't know that mod it's quite simple:
If you post an URL in the Forums, this Mod just loads the <title>XXXXXX</title> out of the linked website.

The title won't be read if the following conditions occur:

• The linked page simply has no <title>-Tag
• The page is down or the <title>-Tag is not being found within the first 60 seconds
• The <title>-Tag is not being found within the first 1000 lines of code.

Installation:
Just import the XML via the ACP and thats all.

Uninstall:
Just kill it out of your ACP.

Fixed Typo which got us a parse error

I have tried that yes - disabling AutoTagger but leaving this mod, which is the one I care about more, running, but still posts invisible and this PhP error:

With autotagger off, but external title fetcher ON (under php 7):

[12-May-2017 20:08:35 America/Los_Angeles] PHP Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback instead in /home/*****/public_html/*****.com/forums/includes/functions_newpost.php(196) : eval()'d code on line 68

You could try editing the plugin from your AdminCP.

This seems to be what it doesn't like (at the very end of the plugin code - PLUGIN not PRODUCT):

	$messagetext = preg_replace(
		'#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siUe',
		"convert_url_to_bbcode_callback_auto_title('\\3', '\\1')",
		$messagetext
	);

No idea if this will work or not but you could try replacing that line with

	$messagetext = preg_replace_callback(
		'#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siUe',
		"convert_url_to_bbcode_callback_auto_title('\\3', '\\1')",
		$messagetext
	);

WARNING: If this breaks your forum and you can't get to your AdminCP, disable hooks so you can edit it back.

Do appreciate the help! but it did not solve anything.

When I switched out that code and tested it with PhP 5.6 running, the mod stopped fetching external titles, and the regular URL posted with no conversion to title.

Same result with PhP 7 running, whether I had the other mod (auto tagger), on or off - posts were no longer invisible, but the regular URL posted with no conversion to title.

i.e. the replaced code did eliminate the weird, invisible post behavior, but it also stopped the external title fetcher from fetching external titles, whether in PhP 5.6 or 7.

Try that, works for me

replace

	$messagetext = preg_replace(
		'#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siUe',
		"convert_url_to_bbcode_callback_auto_title('\\3', '\\1')",
		$messagetext
	);

to

	$messagetext = preg_replace_callback(
		'#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siU',
                function($m) { return convert_url_to_bbcode_callback_auto_title($m[3], $m[1]); },		
		$messagetext
	);

Very good! thank you. Now the Title Tag Fetcher (Auto Replace URL with Titletag) mod works at my forum running 4.2.5 with PhP 7 enabled, without making posts invisible.


I wonder if you could take a look at this:
https://vborg.vbsupport.ru/showthrea...07#post2586407
for the other mod, Automatic Tagger From Message Content and Title - the issue seems to be similar in that the threads/posts are happening, but error codes interrupt the process.

This solves the blank pages problem on vB 4.7.5 with PHP 7.1

However, on two SSL (https://) forums, it no longer fetches the page title, whether the URL being fetched is https:// or http://

This is the entire updated plugin:

PHP Code:

if (!function_exists(convert_url_to_bbcode_callback_auto_title)) {
function convert_url_to_bbcode_callback_auto_title($messagetext, $prepend)
{
    $messagetext = str_replace('\"', '"', $messagetext);
    $prepend = str_replace('\"', '"', $prepend);

    static $urlSearchArray, $urlReplaceArray, $emailSearchArray, $emailReplaceArray;
    if (empty($urlSearchArray))
    {
        $taglist = '\[b|\[i|\[u|\[left|\[center|\[right|\[indent|\[quote|\[highlight|\[\*' .
            '|\[/b|\[/i|\[/u|\[/left|\[/center|\[/right|\[/indent|\[/quote|\[/highlight';
        $urlSearchArray = array(
            "#(^|(?<=[^_a-z0-9-=\]\"'/@]|(?<=" . $taglist . ")\]))((https?|ftp|gopher|news|telnet)://|www\.)((\[(?!/)|[^\s[^$`\"'|{}<>])+)(?!\[/url|\[/img)(?=[,.!)]*(\)\s|\)$|[\s[]|$))#siU"
        );

        $urlReplaceArray = array(
            "[url]\\2\\4[/url]"
        );

        $emailSearchArray = array(
            "/([ \n\r\t])([_a-z0-9-]+(\.[_a-z0-9-]+)*@[^\s]+(\.[a-z0-9-]+)*(\.[a-z]{2,4}))/si",
            "/^([_a-z0-9-]+(\.[_a-z0-9-]+)*@[^\s]+(\.[a-z0-9-]+)*(\.[a-z]{2,4}))/si"
        );

        $emailReplaceArray = array(
            "\\1[email]\\2[/email]",
            "[email]\\0[/email]"
        );
    }

    $text = preg_replace_callback($urlSearchArray, "auto_title", $messagetext);

    if (strpos($text, "@"))
    {
        $text = preg_replace($emailSearchArray, $emailReplaceArray, $text);
    }

    return $prepend . $text;
}

function auto_title ($text) {

$options = array( 'http' => array(
        'user_agent'    => 'VBulletin Titletag Fetcher',
        'max_redirects' => 10,
        'timeout'       => 60,
    ) );
$context = stream_context_create( $options );

if ($text[2] == 'www.' or $text[2] == 'Www.' or $text[2] == 'wWw.' or $text[2] == 'wwW.' or $text[2] == 'WwW.' or $text[2] == 'WWw.' or $text[2] == 'wWW.' or $text[2] == 'WWW.') { $text[4] = $text[2] . $text[4]; $text[2] = 'http://'; }

$paged    = @fopen( $text[2] . $text[4], "r" ); #echo $page . "DONE"; 
if ($paged) {
    while (!feof($paged) and ($x < 1000)) { $page .= fread($paged, 8192); $x++; }
    fclose($paged);
}

preg_match("/<title>[\n\r\s]*(.*)[\n\r\s]*<\/title>/", $page, $title);

if ($title[1] == '') { $title[1] = $text[2] . $text[4]; }
return "[url="" . $text[2] . $text[4] . ""]" . preg_replace("/\&.+\;/", '', $title[1]) . "[/url]";
}

}

    $messagetext = preg_replace_callback(
        '#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siU',
                function($m) { return convert_url_to_bbcode_callback_auto_title($m[3], $m[1]); },        
        $messagetext
    ); 


RESOLVED:

See https://vborg.vbsupport.ru/showthread.php?t=323627

You need to have this setting enabled:

allow_url_fopen = On

To simplify updating for PHP 7.x, use attached product. The text files are for information only: Just delete the 1.5c version and import the new xml product (no files to upload).

Please post there for support and I'll do what I can to help.

Thanks djbaxter. So, I did what rhodium suggested in post #114 but what you updated and attached there is different?

How is it different?

[mdawg]

I'm just asking if it is different. I simply did what Rhodium suggested it seems to work, but my forum is http not https.
