Is it possible to get a specific posts page number URL inside an article? For instance, when in the normal loop, the function get_pagenum_link(3) will retrieve something like http://mysite.com/blog/page/3/
The problem is, when on an article is_single() == true that same function does not return the paged results. I understand I'm currently out of the loop, but is there any way I can work around that ?
global $post;
$url = $post ? get_permalink($post->ID) : '';

Hello guys I'm new to MediaWiki and trying to build my own extension. Using this extension I'm trying to show some content blow page heading but only to a page specific to a category.
For that, I'm using two hooks:
onArticleViewHeader ( To add my HTML content below the page heading)
onOutputPageMakeCategoryLinks (To get all the category of page being loaded)
From the first hook, I'm able to show my content using the following code:
public static function onArticleViewHeader( &$article, &$outputDone, &$pcache ) {
$article->getContext()->getOutput()->addHTML("Printed from a hook");
}
The above code prints the HTML below every page heading but I want to load HTML only to a specific page category. So for that, I'm trying to load the category and I'm just trying to call my first hook only if the category gets caught.
public static function onOutputPageMakeCategoryLinks( &$out, $categories, &$links ) {
foreach($categories as $category){
if($category=="my_page_category"){
MyExtentionClass::onArticleViewHeader();
}
}
}
I know I'm calling the hook in a bad manner which is not correct. But I just wanted to call my 1st hook 'onArticleViewHeader' from inside of my 2nd hook so that I can print my HTML only to a page with a specific category.
Just use $article->getPage()->getCategories() in the header hook.
Haven't really got the exact solution of the question I asked but has got the way out to solve the problem I have been facing.
I just tried getting the current categories in the "onArticleViewHeader" itself by using some of MediaWiki's global variables.
global $wgOut;
$title = Title::newFromText( $wgOut->getPageTitle() );
$categories = $title->getParentCategories();
if(isset($categories['Category:my_cat_name']){
//formed my logic here
}
This might help some other people facing this kind of issue.
I just installed Twitter Typeahead (older vesion 0.9.3).
Right now it links to a search.php page which queries the MySQL database to get the results. It gets the results I need, however, when I select the results, I can't figure out how to pass the ID or other information create a link to another page.
Here is the function in the HTML page that's calling the search.php page:
<script>
$(document).ready(function(){
$('input.typeahead').typeahead({
name: 'typeahead',
remote:'search.php?key=%QUERY',
limit : 10
});
});
</script>
Then search.php is called which queries the database correctly and gets the results I need:
<?php
$key=$_GET['key'];
$array = array();
$con=mysql_connect("hostname","username","password");
$db=mysql_select_db("databasename",$con);
$query=mysql_query("select * from customers where clientDisplayName LIKE '%{$key}%' OR clientPhNumber LIKE '%{$key}%' OR clientAltPhNumber LIKE '%{$key}%'");
while($row=mysql_fetch_assoc($query))
{
//$array[] = "<a href='customer-details.php?cid=".$row['id'] ."'><tr><td>" . $row['clientDisplayName'] . "</tr></td></a>";
$array[] = $row['clientDisplayName'];
}
echo json_encode($array);
?>
You can see the comment there, if I use that instead of the array that's uncommented, It will create a link as I desire, however.. it's buggy that way.
By Buggy I mean:
I HAVE to click on the actual text instead of anywhere in the result row
I cannot simply arrow-down and hit enter to select a response (it must be mouse clicked)
and even if it is clicked with the mouse, I can see the whole
Any ideas on what I can do here?
Do not use twitter typeahead. It is abandoned, no longer maintained, it has 250 issues, some of them very serious regarding basic behavior and severe bugs. I would recommend github.com/bassjobsen/Bootstrap-3-Typeahead instead.
I have a site on Wordpress where I am trying to find the best way to create a dropdown which displays data from a custom taxonomy to eventually integrate it into a different site (also on Wordpress).
Where I have go to is trying to obtain the correct Routes/URL's to fetch this information.
I have a Post type called listings which has a taxonomy called listing_area which has different areas where posts are associated, e.g. Wales, East Anglia.
I have got so far that I have decided to use the Plugin WP-API (whether this is the right thing I don't know, I am aware that Wordpress now had an API in it's new update). I have managed to get this URL working and pulling in the terms of listing_area - http://scd.blaze.wpengine.com/wp-json/taxonomies/listing_area/terms/174
This is the test page I have going which is linking to these URL's in turn -
http://scd.blaze.wpengine.com/test/
I have no idea if I'm doing the right thing here and I have very basic knowledge on it and would hugely appreciate it if someone could point me in the right direction!
Thanks
You're going on the right path, but I suggest to work straight with the fresh Wordpress REST API if you can upgrade your websites to 4.4. Otherwise you can still use your REST plugin as it is pretty much the same. I'll try to explain how to go through what you want to achieve (navigate through terms of a distant Wordpress website and display posts related to this terms).
Get the terms from the other WP
Using the new WP REST API, here is a small function that you can use to get your taxonomy terms:
public function getDistantTerms($taxonomy) {
$response = wp_remote_get('http://www.yourwebsite.com/wp-json/wp/v2/terms/' . $taxonomy);
if(is_wp_error($response)) {
return array();
}
return json_decode(wp_remote_retrieve_body($response));
}
Here I make use of wp_remote_get function to get the JSON return from the REST function terms by passing it as parameter the taxonomy slug (ex:listing_area) - here is a demo of what it returns. Add this function to your functions.php then use it in your template to build up your select:
<select name="term_select">
<option value="">Please choose a term</option>
<?php foreach(getDistantTerms('listing_area') as $term): ?>
<option value="<?php echo $term->slug; ?>"><?php echo $term->name; ?></option>
<?php endforeach; ?>
</select>
It seems that's pretty much what you actually got.
Link your select to a custom template
So the next step is to redirect to a page that list the posts of the term you choose. First we handle the redirection in JS:
$('select[name="term_select"]').change(function() {
if($(this).val() != "") {
window.location = "/show-post-term/" + $(this).val();
}
});
We add a little rewrite rule to redirect this url (change it to whatever you want) to a template we'll name distant-posts.php (all of this take place in your theme functions.php):
1. Add the rewrite rule
add_action('init', 'distantposts_rewrite_rules');
function distantposts_rewrite_rules() {
add_rewrite_rule('show-post-term/([^/]+)/?$', 'index.php?term_slug=$matches[1]&distant_post=true', 'top');
}
2. Add two query vars
add_filter('query_vars', 'distantposts_query_vars' );
function distantposts_query_vars($vars) {
$vars[] = 'term_slug';
$vars[] = 'distant_post';
return $vars;
}
3. Redirect to the template if query vars are set
add_filter('template_include', 'yourpluginname_blah_template_include', 1, 1);
function yourpluginname_blah_template_include($template) {
global $wp_query;
$distant_post = $wp_query->query_vars['distant_post'];
$term_slug = $wp_query->query_vars['term_slug'];
if($distant_post && $term_slug) {
$tpl = locate_template(array('distant-posts.php'));
if(!empty($tpl)) {
return $tpl;
}
}
return $template;
}
So in short what we're doing here: we add a rule that handle the /show-post-term/term-slug URL by redirecting it to index with two query vars: one that tell we're in a "distant posts" mode and one that carry the term slug. Then we declare those query vars to Wordpress, and use them to change the template that Worpdress should display if they're set.
List the distants posts from the taxonomy term
Back to the REST API. We use the GET REST function posts by passing it as GET parameters the taxonomy name as key, and the term slug as value. Here is a demo of what kind of return you get.
An important note before going further: after you updated to WP 4.4, you need to change your taxonomy declaration in order to make this work. You need to add to your declaration the parameter show_in_rest set to true, and set query_var to true.
So we add this little function to functions.php to retrieve the posts from the template:
public function getDistantPosts($taxonomy, $term) {
$response = wp_remote_get('http://www.yourwebsite.com/wp-json/wp/v2/posts?' . $taxonomy . '=' . $term);
if(is_wp_error($response)) {
return array();
}
return json_decode(wp_remote_retrieve_body($response));
}
And then in your template, you call it this way:
global $wp_query;
$posts = getDistantPosts('listing_area', $wp_query->query_vars['term_slug']);
Then use the $posts array to display your posts (it contain regular post objects).
Going further
A few things that you may want to do now that you have the context established:
Add cache to the REST return
In order to avoid to overload your main website server, you should really consider caching your REST calls results. I will not detail this here as there is some work to do on it, but a good start could be this script.
Add pagination to your distant posts template
If you have a lot of posts associated to your terms, you might want to add a pagination. You can change a bit the distant posts REST function to add the page parameter for this - see the documentation.
Add a "single page" for your distant posts
You might want to have individual pages for your distant posts on your main website, as the text might be too long for the list mode. You can start on the distant-posts.php code and add a post_id query var, then use the REST posts function to get your post like this : /wp-json/wp/v2/posts/<post_id>
To understand the basics of the WP REST API I strongly suggest you to visit the wp-api.org website. There is a pretty good article on the REST API on wpmudev.org that you can read too. If you need to learn about the REST basics, I suggest you to read the Wikipedia post about it.
Hope you'll manage to get through this, have fun!
I found this this url got me the results I needed -
http://scd.blaze.wpengine.com/wp-json/posts?type=listings&filter[listing_area]=channel
my post type being listings and the slug of my term channel
Please help to correct a filter problem.
Its a facebook fan page like website for users to add and like fanpages for each other.
want to do:
no duplicate Facebook fan page gets added to site database.
filter (http or https) and facebook fan-page link (with or without / ) as same.
example
http://www.facebook.com/Shareitto
https://www.facebook.com/Sharetto
http://www.facebook.com/Sharetto/
They all could be added to the site (this is problem, I want to filter)
Below is the complete code with filter
if(isset($_POST['add'])){
if(!preg_match("/\bfacebook.com\b/i", $_POST['url']))
{$msg = "<div class=\"msg_error\">ERROR: You need to add facebook page!
</div>";}
else if($_POST['title'] == ""){$msg = "<div class=\"msg_error\">
ERROR: Title can't be empty!</div>";}
else{
mysql_query("INSERT INTO 'facebook' (user, facebook, title, cpc)
VALUES('{$data->id}', '{$protectie['url']}', '{$protectie['title']}',
'{$protectie['cpc']}' ) ");
$msg = "<div class=\"msg_success\">Page added with success!</div>";
}}
?>
If need more, please reply!
The way I'd approach this is to only store the part of the URL after http://facebook.com/, so in the case you mentioned only "Sharetto" is stored. This makes lookups a lot easier, as performing REGEX in MySQL is an unnecessary use of resources in this case. When pulling out the data from the database you would then prepend the fanpage name with the Facebook URL.
I would pick out the important part of the URL using a regular expression like this:
$url = "http://www.facebook.com/Sharetto/";
$matches = array();
if (preg_match('~^https?://(?:www\.)?facebook.com/(.+)/?$~',$url,$matches)) {
$fanpageName = $matches[1]; // In this case: "Sharetto"
// Do lookup in DB for $fanpageName, not $url
}
Basically, throw away the Facebook URL completely, and just pick out the important part.
I have a problem with pagination on results. I need to order the results by title and by alphabetic order (A->Z) , its possible? I tried some different approaches but none work as needed, the best i have so far is list the results by title and ASC but if i go to "next page" i get always the same results.
Any idea?
Thanks.
It looks like you are on the right track but you are getting the same results on each page because Wordpress is losing track of what page it is on internally. This is done with the $paged global.
If you are modifying the sorting with query_posts, make sure you are also passing in the global $paged var ('&paged='.$paged ). Also, make sure that global exists on the page as well before calling it in query_posts, otherwise it will always be 0 and return the same results on each page. If you are using WP_Query instead of query_posts, this is a good run down. http://weblogtoolscollection.com/archives/2008/04/19/paging-and-custom-wordpress-loops/
This is what I'm using, add it on index.php
<?php
$posts = query_posts($query_string . '&orderby=title&order=asc');
?>
In your case, you might also need to put is_home() condition
<?php
if(is_home()){
global $query_string;
query_posts($query_string . '&orderby=title&order=asc');
}
?>
Hope it helps :)
