First post image in the portal?

[Divvy]

Hello friends,

Maybe someone can help me...
I want to show in my portal, only the first image in my post, but I don't know how to make that possible.

I installed this plugin to cut off characters:
http://mods.mybb.com/view/portal-announcement-cut-off

But doesn't work like I want, because a URL can have different numbers of characters...
Unless someone could change the code to appear only the first image inside the [ img ] [ /img] tags.
Is that possible?

PHP Code:

<?php

if(!defined("IN_MYBB"))
{
    die("Direct initialization of this file is not allowed.<br /><br />Please make sure IN_MYBB is defined.");
}
$plugins->add_hook("portal_announcement", "portalannc");



function portalannc_info()
{
    return array(
        "name"            => "Portal Announcement Cut Off.",
        "description"    => "It sets a minimum of characters for portal announcements.",
        "website"        => "http://www.mybb.com/",
        "version"        => "1.0",
        "author"        => "bubulang",
        "authorsite"    => "http://community.mybb.com/user-29135.html",
        "compatibility"  => "16*",
        'guid'        => 'a18f4b6eed189c9ffd4e4708708c15dc'
    );
}

function portalannc_activate()
{
    global $db;
    
    $query = $db->simple_select("settinggroups", "gid", "name='portal'");
    $gid = $db->fetch_field($query, "gid");
    
    $setting = array(
        'name' => 'patcutoff',
        'title' => 'Portal Announcement Cut Off',
        'description' => 'Set a minimum of characters for portal announcements?',
        'optionscode' => 'yesno',
        'value' => 'yes',
        'disporder' => '20',
        'gid' => intval($gid)
    );
    $db->insert_query('settings',$setting);
    
    
    $characters = array(
        'name' => 'characters',
        'title' => 'Characters',
        'description' => 'Number of characters before the announcement is cut off',
        'optionscode' => 'text',
        'value' => '',
        'disporder' => '21',
        'gid' => intval($gid)
    );
    $db->insert_query('settings',$characters);
    
    $cutoffmessage = array(
        'name' => 'cutoffmessage',
        'title' => 'Announcement Cut Off Message',
        'description' => 'Message to be displayed when announcemet is cut off',
        'optionscode' => 'text',
        'value' => '..... More',
        'disporder' => '22',
        'gid' => intval($gid)
    );
    $db->insert_query('settings',$cutoffmessage);
    

rebuild_settings();
}

function portalannc_deactivate()
{
    global $db;

$db->query("DELETE FROM ".TABLE_PREFIX."settings WHERE name='patcutoff'");
$db->query("DELETE FROM ".TABLE_PREFIX."settings WHERE name='characters'");
$db->query("DELETE FROM ".TABLE_PREFIX."settings WHERE name='cutoffmessage'");
    
rebuild_settings();
}
    
function portalannc()    
{
global $mybb, $announcement;

if($mybb->settings['patcutoff'] == 1 AND $mybb->settings['characters'] < my_strlen($announcement['message'])){
$announcement['message'] = my_substr($announcement['message'], 0, $mybb->settings['characters']);
$announcement['message'] .= "[url=".$mybb->settings['bburl']."/".$announcement['threadlink']."]".$mybb->settings['cutoffmessage']."[/url]";
}
}

?>

Can someone help me?
Thank you!

replace the function portalannc() with this

PHP Code:

function portalannc()    
{
    global $mybb, $announcement;

    if($mybb->settings['patcutoff'] == 1 AND $mybb->settings['characters'] < my_strlen($announcement['message']))
    {
        $pos = stripos($announcement['message'], "[/img]");
        if($pos !== false)
        {
            $mybb->settings['characters']) = $pos + 6;
        }
    
        $announcement['message'] = my_substr($announcement['message'], 0, $mybb->settings['characters']);
        $announcement['message'] .= "[url=".$mybb->settings['bburl']."/".$announcement['threadlink']."]".$mybb->settings['cutoffmessage']."[/url]";
    }
}

WOW perfect !!! Thank you my friend

I only removed ")" from:

PHP Code:

$mybb->settings['characters']) = $pos + 6; 


Because was causing an error...
Thank you once again
Rep on you
