Next and Prev article title, instead of only navigation buttons

[GabyZ]

Hi, in all articles there are next and prev article buttons, is there any way to have instead the buttons the title of the next and prev article? This would be more user-friendly i think and more SEO.

thanks in advance

[brian]

Sorry I've not seen anything that does that but it sounds a good idea.

Open a new topic, please. You're Off Topic.

That's not a big deal.

In components/com_content/content.php replace the code from line 1490 to the end of the if statement in the function showItem()  by the following:

Code: Select all

            // array of content items in same category correctly ordered
            $query = "SELECT a.id, a.title"
            . "\n FROM #__content AS a"
            . "\n WHERE a.catid = " . (int) $row->catid
            . "\n AND a.state = " . (int) $row->state
            . ($access->canEdit ? '' : "\n AND a.access <= " . (int) $gid )
            . $xwhere
            . "\n ORDER BY $orderby"
            ;
            $database->setQuery( $query );
            $list = $database->loadObjectList();

            // this check needed if incorrect Itemid is given resulting in an incorrect result
            if ( !is_array($list) ) {
                $list = array();
            }
            // location of current content item in array list
            $prev    = null;
            $current = array_shift( $list );
            $next    = array_shift( $list );
            while ( $current->id != $uid ) {
                $prev    = $current;
                $current = $next;
                $next    = array_shift( $list );
            }
            $row->prev = '';
            $row->next = '';
            if ( !empty( $prev ) ) {
                $row->prev       = $prev->id;
                $row->prev_title = $prev->title;
            }
            if ( !empty( $next ) ) {
                $row->next       = $next->id;
                $row->next_title = $next->title;
            }
        }

        // page title

Next, replace two lines of the method Navigation() in components/com_content/content.html.php, i.e. line 921

Code: Select all

                            <?php echo _ITEM_PREVIOUS, $row->prev_title; ?></a>

and line 938:

Code: Select all

                            <?php echo $row->next_title, _ITEM_NEXT; ?></a>

Last thing to do is to set the constants _ITEM_PREVIOUS and _ITEM_NEXT in your language file in a way that makes sense. I use

Code: Select all

DEFINE('_ITEM_PREVIOUS','< ');
DEFINE('_ITEM_NEXT',' >');

If you don't want to edit the code yourself, I have added both files as an attachment. Just copy the files over the existing ones. Don't forget to make a backup first!

Great! thanks  , i love this forum and support, simply and fast 

[theLoneDeranger]

Yes, no posts for at least 30 days and I do want to reply. A belated compliment to Nibra ... Simple and elegant, well-documented. Nibra RULES!!

Just a tip for others to even further benefit from Nibra's great logical mind. Instead of "just" showing the Prev/next articles' titles, you may even consider adding (ehm..) author, title_alias, publication/lastmod date or META to either the hyperlink text or (what I did) to the hyperlink alt/title attribute.

For instance, to use title_alias, metakey and metadesc just add them to the query in /components/com_content/content.php like this

Code: Select all

// array of content items in same category correctly ordered
            $query = "SELECT a.id, a.title, a.title_alias, a.metakey, a.metadesc"

A bit down also add them here like this

Code: Select all

            if ( !empty( $prev ) ) {
                $row->prev       = $prev->id;
                $row->prev_title = $prev->title;
                $row->prev_title_alias = $prev->title_alias;
                $row->prev_metakey = $prev->metakey;
                $row->prev_metadesc = $prev->metadesc;
            }
            if ( !empty( $next ) ) {
                $row->next       = $next->id;
                $row->next_title = $next->title;
                $row->next_title_alias = $next->title_alias;
                $row->next_metakey = $next->metakey;
                $row->next_metadesc = $next->metadesc;

Then in the file /components/com_content/content.html.php use them any way you want, such as i.e. put the title_alias in the hyperlinks title tag by doing this

Code: Select all

<th class="pagenav_prev">
	<a title="<?php echo $row->prev_title_alias; ?>" href="<?php echo $row->prev; ?>"><?php echo $row->prev_title; ?><span class="prevnext_small"><?php echo _ITEM_PREVIOUS;?></span></a>
</th>

O, never mind the span class there, that just me. Also sorry I left out the line numbers. My line numbers are completely messed up anyway with all the mods. See Nibra's original post.

Naturally you can use other php to just fill the string, i.e. in pseudo code
HYPERLINK_TITLE_ATT = ''

if title_alias not empty
add title_alias tot the HYPERLINK_TITLE_ATT
/if

if metadesc not empty
strip to set number of characters
add to HYPERLINK_TITLE_ATT
else
  $metaexist = false;
/if

then do your thing with pseudo codesomething

or perhaps even pseudocode
if $metaexist = false && user has edit rights
echo HEY DUDE YOU FORGOT THE METADATA FOR THE (prev\next) ARTICLE something

else
echo something
/if

What about the navigation between pages of the same article? I use a mambot (mospaging_scrool) to show pages in an horizontal box wich allows to select pages to load.

It also replaces the prev and next button to navigate between pages ot the same article, do vou think that the anchor text for next and prev links could be change with the next/prev page title?

Here's the code of the mambot.
The part wich interests me is:

  $row->text .= '' . $prev . ' - ' . $next .'';

All the code...

registerFunction( 'onPrepareContent', 'botMosPaging_scroll' );



/**

* Page break mambot

*

* Usage:

* {mospagebreak_scroll}

* {mospagebreak_scroll title=The page title}

* or

* {mospagebreak_scroll heading=The first page}

* or

* {mospagebreak_scroll title=The page title&heading=The first page}

* or

* {mospagebreak_scroll heading=The first page&title=The page title}

*

Hi all - as this post is quite old - I'm using Joomla V 1.5.7 and the content.php file only has around 40 lines, not 1400.

Please can someone highlight how to update the prev and next links to state their associated titles dynamically instead.

Many thanks,
Sean

[seang]

Can someone please help?

[alex_blanc]

Ditto that 'please'.
And, how to change << Prev - Next >> at the bottom of a multi-page article to read << Previous - Next Part of Article>>.
Thanks all.

[hanen]

Hi
You just go to plugins then Content - Page Navigation and change the setting.
i hope i could help you.

[ezra222]

I just applied this mod to a site of mine, works great except there is no space between prev & article title and next & article title.

For example: < PrevArticle Title Article TitleNext >

Any help?

Thanks.

[lividsnails]

I can't believe this topic is so old and no one has had this problem since. My navigation links only say "Prev" and "Next" and I really need them to include the title of the previous and next article, otherwise they are essentially useless for both users and search engines. I see no options for adding the title in the plugin parameters and I'm not sure how to change the code since the suggestions above were made several years ago and I'm now using Joomla 1.5.14. Does anyone have more recent information on how to achieve this?

[brian]

Check the joomla extensions directory as there are solutions available

[lividsnails]

Ok thanks! The one plugin is in Chinese so i couldn't figure that one out but the PageNav one works great (except yeah there's no space between the article title and the "prev"/"next" but as they say good enough for government work! lol)
