I would like to customize the URL link generated by next_post_link() and previous_post_link() (Wordpress post Navigation Functions)
Now returns a URL link like this:
http://wwww.misite.com/notice1 (for example)
I would like returns a custom URL link like this:
http://www.misite.com/shop/notice1
My code is :
$content .= next_post_link('<div class="nav-prev">« %link</div>');
$content .= previous_post_link( '<div class="nav-next">%link »</div>');
You try to retrieve the result of function that don't return anything. See the WordPress Codex for more info about these functions.
If you want to store the link, you can use the get_next_posts_link() function instead (see here). You can also find get_previous_posts_link().

I have an article with several pages in my wordpress blog. if for example i have the following link in my blog :
http://example.com/heartbreaking-photos
any idea how can i change the link of the second page from
http://example.com/heartbreaking-photos/2
to http://example.com/heartbreaking-photos/CUSTOM-STRING
CUSTOM-STRING aimed to be a custom title inside the page
To achieve this, you will need to do 2 things:
Disable the default WordPress canonical redirect - this is necessary, because WordPress will always redirect to the /2/ page when it encounters the page parameter in the URL or query args.
Add a custom rewrite rule to direct your custom title to the second page of your page - this is essentially necessary to allow the link format that you want.
In terms of code, this is what you need (this is a working solution, I've just tested it locally):
// Removes the canonical redirection
remove_filter( 'template_redirect', 'redirect_canonical' );
// Add custom rewrite rules
add_action( 'init', 'my_add_custom_rewrite_rules' );
function my_add_custom_rewrite_rules() {
// Slug of the target page
$page_slug = 'heartbreaking-photos';
// Page number to replace
$page_num = 2;
// Title you wish to replace the page number with
$title = 'custom-string';
// Add the custom rewrite rule
add_rewrite_rule(
'^' . $page_slug . '/' . $title . '/?$',
'index.php?pagename=' . $page_slug . '&page=' . $page_num, 'top'
);
}
There are three things you might want to configure or change here:
$page_slug - this is the slug of your page, in your case this is heartbreaking-photos
$page_num - the number of your pagination page, in your case this is 2
$title - the title you wish to use instead of your page number 2.
Feel free to alter the code as you wish, or copy it to cover more additional cases, similar to this one.
EDIT
Important: Once you use the code, go to Settings > Permalinks and click the "Save Changes" button. This will rebuild your rewrite rules, and is necessary for the solution to work.
Hope that helps. Let me know if you have any questions.
You can try this codex. Pass the arg and you will get page id, page title and use those
https://codex.wordpress.org/Function_Reference/get_pages
Or you can call page title by page id
$pagetitle= get_post_field( 'post_title', $page_id );
Ok, so basically you don't want to display the navigation link under the page (use css or modify the post template in the child theme) and add your custom link. If I understand it well:
Remove navigation links (depends on your theme, but basically):
.nav-links { display: none; }
You can add the custom link through function + custom fileds:
create a custom field, for example "my-url" in your post, see codex: https://codex.wordpress.org/Custom_Fields
add to your functions.php (in the child theme or in a custom site plugin):
function my_page_add_to_content( $content ) {
if ( ! empty(get_post_meta( get_the_ID(), 'my-url', true ) ) {
$content .= 'URL TEXT HERE'
}
return $content;
}
add_filter( 'the_content', 'my_page_add_to_content' );
I have set a blog page that is separate from my static home page.
I have modified the “[...]” link that comes after each post’s excerpt on the blog page by using a filter function.
To do this, I used WordPress’s “excerpt_more” hook.
add_filter('excerpt_more', 'new_excerpt_more');
function new_excerpt_more($more) {
global $post;
return '... <br clear="all"/><a class="moretag" href="'. get_permalink($post->ID) . '">Continue Reading</a>';
}
The problem I am having is that, for some reason, this works for every post, except the very first post of the blog page.
Is there something different or special about the very first post of the blog page that would make it not go through this filter hook?
Thank you very much for any help.
Try with this one:
add_filter('excerpt_more', 'new_excerpt_more');
function new_excerpt_more($more) {
return '... <br clear="all"/><a class="moretag" href="'. get_permalink( get_the_ID() ) . '">Continue Reading</a>';
}
Also, if in Wordpress a post has a manual excerpt, the excerpt_more filter wont get executed. So it's always recommended to check that, just in case.
I've a custom post type "video" and wanted to show videos like youtube, dailymotion in a specified area using WP default oembed script.
So i'm using a custom field"video url", but the problem is that oembed work in the_content not with custom field. so how can i do this. or any other solution
If the custom field only contains the video URL like http://www.youtube.com/watch?v=dQw4w9WgXcQ, then you can get the oEmbed HTML code with wp_oembed_get:
$videourl = 'http://www.youtube.com/watch?v=dQw4w9WgXcQ';
$htmlcode = wp_oembed_get($videourl);
echo $htmlcode;
If your custom field contains more than just the URL, you could use the the_content filter to do the same thing the the_content-function does:
$content = "<h2>this video is great</h2>\n<p>check it out</p>\n"
. "[embed]http://www.youtube.com/watch?v=dQw4w9WgXcQ[/embed]";
$htmlcode = apply_filters('the_content', $content);
echo $htmlcode;
Here is a complete answer to your question. It is also a cleaner and quicker method, using wp_oembed_get, rather than shortcode. Of course, change video_url to the name of your custom field.
This code checks that the video_url field is not empty, then oEmbeds the video.
<?php if (!((get('video_url', TRUE))=='')) {
echo wp_oembed_get( get('video_url', true) );
}?>
I'm stuck. I posted this on WordPress.StackExchange and they suggested I try at WebApps.StackExchange, and they suggested I try here. So, apologies for the multiple posts if you follow all those!
I have a client blog using bit.ly pro to generate custom short urls (ie foo.co). I want to show the regular horizontal version of the Twitter button, with tweet-count, and have the link that goes to the post use their custom bit.ly pro url.
I have installed Joost de Valk's Bit.ly Shortlinks plugin, which successfully converts normal WP shortlinks (wp_get_shortlink()) to the custom Bit.ly pro URL elsewhere in the site, but Twitter seems to trump that and render everything with the default t.co domain instead.
I've looked at the suggestions from this question but using the # as the data-url doesn't work, and the suggested Twitter support pages don't seem to contain any info on how to get Bit.ly to work (though they say they're going to).
Here's the function I created to insert the button in my theme - any ideas on where I'm going wrong? this is used to insert the button both within the Loop and on single-post pages.
function tweet_this() {
global $post;
ob_start();
$tweet = wp_get_shortlink();
echo '<script src="http://platform.twitter.com/widgets.js" type="text/javascript"></script>Tweet';
return ob_get_clean();
}
In case it helps, this function does work, except it doesn't render the tweet-count:
function tweet_this() {
global $post;
ob_start();
$tweet = sprintf( __('%1$s %2$s'), $post->post_title, wp_get_shortlink() );
echo '<a class="tweethis" href="http://twitter.com/intent/tweet?text=' . urlencode( $tweet ) . ' via #clientname">Tweet this</a>';
return ob_get_clean();
}
Let me know if you need more info - and thanks in advance for any help you can throw my way!

function tweet_this() {
global $post;
$tweet = get_permalink(); //replace with your code
$tweetmarkup = '<script src="http://platform.twitter.com/widgets.js" type="text/javascript"></script>Tweet';
echo $tweetmarkup;
}
This works for me, but I don't have the WPShortlinks installed, so I replaced it with the permalink. You should be able to replace the permalink with your wp_get_shortlink and it should work.
I am trying to learn more about Wordpress and creating plugins. I have seen an existing plugin use a technique where you can add a 'reference' to it within your posts and WP will parse it and replace it with the plugins own content. The example i am referring to is the NextGen gallery which uses the following code
[nextgen id=9]
I have tried searching for how this technique works but trying to find something that you don't know the name of is pretty difficult!
Can anyone point me towards some resources about how to use this feature of WP?
The technique is called shortcodes.
add_shortcode('my-content','my_plugin_shortcode');
function my_plugin_shortcode($atts, $content = null) {
$atts = shortcode_atts($my_default_atts,$atts); // $atts is now an associate array
$my_content = 'This is some content.';
return $my_content;
}
Then, if you have a post with the following content:
Hey, here is some content.
[my-content]
You will get the following output when the post is displayed:
Hey, here is some content. This is
some content.
If you passed a shortcode like [my-content id="9" test="test"], then the $atts variable in the above function would be like the following array declaration
$atts = array('id'=>9, 'test'=>'test');
The $content variable only has content when you use matching shortcodes around some text:
[my-content]This is some test
content.[my-content]
