Open Graph meta data for coppermine

<< < (2/8) > >>

Anturaju93:
I think i need to edit theme.php and add this function function pageheader($section, $meta = '') from sample theme but i don't know how to construct the $meta
I tried $meta = <meta property="og:url" content="link here" /> but is not working, my site is crashing.   

--- Code: ---//meta open graph
    $meta = <<<EOT <meta property="og:url" content="link aici" /> EOT;
--- End code ---
Some ideas ?

Anturaju93:
I added this to theme.php :

--- Code: ---/******************************************************************************
** Section <<<pageheader>>> - START
******************************************************************************/
function pageheader($section, $meta = '')
{
    global $CONFIG, $THEME_DIR;
    global $template_header, $lang_charset, $lang_text_dir;

    // Variabile pentru aflarea pid-ului unic START
    $superCage = Inspekt::makeSuperCage();
    $pid = $superCage->get->getInt('pid');
    // Variabile pentru aflarea pid-ului unic END

    $custom_header = cpg_get_custom_include($CONFIG['custom_header_path']);

    $meta = '<meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=$pid" />';

    $charset = ($CONFIG['charset'] == 'language file') ? $lang_charset : $CONFIG['charset'];

    header('P3P: CP="CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE"');
    header("Content-Type: text/html; charset=$charset");
    user_save_profile();

    $template_vars = array(
        '{LANG_DIR}' => $lang_text_dir,
        '{TITLE}' => theme_page_title($section),
        '{CHARSET}' => $charset,
        '{META}' => $meta,
        '{GAL_NAME}' => $CONFIG['gallery_name'],
        '{GAL_DESCRIPTION}' => $CONFIG['gallery_description'],
        '{SYS_MENU}' => theme_main_menu('sys_menu'),
        '{SUB_MENU}' => theme_main_menu('sub_menu'),
        '{ADMIN_MENU}' => theme_admin_mode_menu(),
        '{CUSTOM_HEADER}' => $custom_header,
        '{JAVASCRIPT}' => theme_javascript_head(),
        '{MESSAGE_BLOCK}' => theme_display_message_block(),
    );

    $template_vars = CPGPluginAPI::filter('theme_pageheader_params', $template_vars);
    echo template_eval($template_header, $template_vars);

    // Show various admin messages
    adminmessages();
}
/******************************************************************************
** Section <<<pageheader>>> - END
******************************************************************************/

You can see that i defined $meta = '<meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=$pid" />'; witch displays <meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=$pid" /> in browser meta data, but i can`t make the URL to by dynamic: imagini.moinesti.biz/displayimage.php?pid=$pid stays the same and does not change into imagini.moinesti.biz/displayimage.php?pid=140 etc. ...

E. William:
Try replacing:

--- Code: ---    $meta = '<meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=$pid" />';
--- End code ---

with:

--- Code: ---    $meta = '<meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=' . $pid . '" />';
--- End code ---

so it doesn't read $pid as part of the url, but as a variable.

Not sure if it'll do the trick, that depends on other parts of the code as well, but it'll get you closer to where you want to be.

Yes, is working now, thanks.   8)
This is only half fixed, i need now to display this custom meta data only on displayimage.php and i need to insert another meta data into $meta , the image file location for facebook to use with the share button to create a timeline story. <meta property="og:image" content="dynamic and direct path to file location" />
Facebook share looks very nice now with this new open graph data :)

E. William:
That code would look something like:


--- Code: ---    $meta = '<meta property="og:url" content="http://imagini.moinesti.biz/displayimage.php?pid=' . $pid . '" />';

    if ($CONFIG['make_intermediate'] && cpg_picture_dimension_exceeds_intermediate_limit($CURRENT_PIC_DATA['pwidth'], $CURRENT_PIC_DATA['pheight'])) {
        $meta .= '<meta property="og:image" content="http://imagini.moinesti.biz/' . "{$CURRENT_PIC_DATA['filepath']}" . 'normal_' . "{$CURRENT_PIC_DATA['filename']}" . '" />';
    } else {
        $meta .= '<meta property="og:image" content="http://imagini.moinesti.biz/' . "{$CURRENT_PIC_DATA['filepath']}" . "{$CURRENT_PIC_DATA['filename']}" . '" />';
    }
--- End code ---

I must say I'm not a coder either, so I can't guarantee this will work. You may have to tweak the code here and there.
