I am trying to add a div to my sidebar and I only want this block to show to administrators. How can I check if a user is an administrator in php? I am trying to add this to myskin.php file and dont know how to do it. I have been using something like this to check if a user is logged in,
<?php if($this->data['loggedin']) { ?>
Is there anything similar to that to check if that user is a sysop?
The code in the answer by *blackops_programmer* checks whether the user can protect pages. Per default, that would be sysops, but the permission can be assigned or removed from any group.
If what you want to do depends on the right to protect pages, then checking the permission is the correct way (except you should use $this->getUser(), not $wgUser).
However, if you really want to check for the sysop group, use this:
if ( in_array( 'sysop', $this->getUser()->getEffectiveGroups() ) {
echo 'Hello People';
}
I think I got it. I added the following to my skin template to add special conditions for sysops and non sysops:
<?php
global $wgUser;
if($wgUser->isAllowed('protect')) {
// if sysop
echo 'Hello People';
}
else {
echo 'Yo';
}
?>
I got the idea from here: Check if user is sysop
If there is a better way to do this, please do let me know. But so far, the above seems to work when I added that code to the basetemplate of my skin.

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'm searched about this question but all i found was about wordpress not for php or html, my website is based on bootstrap and i want to show a div for onl registered users and give them a message like you must login to view or something like that, is there any way to do that? i can't find topics about it.
i've tried this one:
if (is_user_logged_in()) {
// logged in content
} else {
// not logged in content
}
but it seems to work only on wordpress, i can't find the php or htm version.
You cant write logical code in HTML only you have to embed script or logical language with it, its a markup language only. You can achieve it with php as you said but syntax should be like this for if else statement
<?php
if ( $a > $b ) {
echo "a is greater than b" ;
} else {
echo "a is NOT greater than b" ;
}
?>
You should check in your condition if there is logged in user in session or not.
I have a site on Wordpress where I am trying to find the best way to create a dropdown which displays data from a custom taxonomy to eventually integrate it into a different site (also on Wordpress).
Where I have go to is trying to obtain the correct Routes/URL's to fetch this information.
I have a Post type called listings which has a taxonomy called listing_area which has different areas where posts are associated, e.g. Wales, East Anglia.
I have got so far that I have decided to use the Plugin WP-API (whether this is the right thing I don't know, I am aware that Wordpress now had an API in it's new update). I have managed to get this URL working and pulling in the terms of listing_area - http://scd.blaze.wpengine.com/wp-json/taxonomies/listing_area/terms/174
This is the test page I have going which is linking to these URL's in turn -
http://scd.blaze.wpengine.com/test/
I have no idea if I'm doing the right thing here and I have very basic knowledge on it and would hugely appreciate it if someone could point me in the right direction!
Thanks
You're going on the right path, but I suggest to work straight with the fresh Wordpress REST API if you can upgrade your websites to 4.4. Otherwise you can still use your REST plugin as it is pretty much the same. I'll try to explain how to go through what you want to achieve (navigate through terms of a distant Wordpress website and display posts related to this terms).
Get the terms from the other WP
Using the new WP REST API, here is a small function that you can use to get your taxonomy terms:
public function getDistantTerms($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
I am trying to get the html of top.links using the following ways:
$blockHtml = Mage::getModel('cms/block')->getBlockHtml('top.links')
$blockHtml = Mage::app()->getLayout()->getBlock('top.links').toHtml()
$blockHtml = Mage::getSingleton('core/layout')->getBlock('top.links')->toHtml()
None of above is working for me, how I can do this?
Thanks.
UPDATE
I used
$layout = Mage::getSingleton('core/layout');
$block = $layout->createBlock('page/html')->setTemplate('page/html/top.links.phtml')->toHtml();
With the help of this question Add Top Links on condition basis in magento but still no luck. During this try I found that the use of top.links.phtml is deprecated, any idea which template should I use for the links?
I think there is some dependency for top.links.phtml file, that's why it isn't working, when I tried to get footer.phtml it worked perfectly with above method.
Just like the op, I tried many ways without success. The following simple line finally does it:
<?php echo $this->getLayout()->getBlock('top.links')->toHtml(); ?>
Wow! I was able to find a correct answer finally :) Load block outside Magento, and apply current template
So by following the the above question's answer, I did this to get generated top.links
$layout = Mage::app()->getLayout();
$layout->getUpdate()
->addHandle('default')
->load();
$layout->generateXml()
->generateBlocks();
echo $layout->getBlock('top.links')->toHtml();
If you have created CMS block named 'block_identifier' from admin panel. Then following will be code to call them in .phtml
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml();
?>
Please,used the belowCodes.This will be working
echo $this->getLayout()->getcreateBlock('page/template_links')->toHtml();
Tumblr is really impressive in the sense that it allows users to customize their profiles and such. You're allowed to edit the HTML and CSS of your profile.
This is something I want to apply to my own site. However, I'm sure that this will be a big burden on security.
Does anyone have any tips or precautions for a feature like Tumblr's? Also, is it advisable to store the editable HTML and CSS in a database? Thank you :D
P.S.
What about server-side scripting? Lets say I wanted to grant the option of allowing the user to script a button that does something to the database. Any thoughts on how to do this?
This is a very difficult thing to get right, in my experience, if you want users to be able to use absolutely all of HTML/CSS. What you could do, however, is strip all CSS and HTML attributes, and only put "safe" code on a whitelist.
Examples
<p>This is legal code.</p>
<p><a onload="alert('XSS!')">The attribute should be filtered out</a></p>
<p>This is a legal link.
Of course you should still sanitize the href attribute!</p>
<h1>This is bad, because the rest of the page is going to huge,
so make sure there's a closing tag
<style>
.blue {
color: #00f; // keep this (by whitelist)
strange-css-rule: possibly-dangerous; // Filter this out!
}
</style>
Those are just some of the pitfalls you can encounter, though.
I'm not familiar with Tumblr, but I'm pretty sure they're doing something similar to this.
As for the database question, of course you can store HTML and CSS in a database, many systems do this. In your case, you would just need one representation anyway, anything else would just confuse the user ("Why is my CSS rule not applied; it's right there in the code!")
If you are using php then, for database issue you can use mini API system. For example, you want user to allow comment on something and save it in your database, then you can use API like this.
First, api.php file, (URL Location: http://yoursite.com/api.php)
<?php
// ID and Key can be different for all users.
// id = 1234
// key = 'secret_key'
// function = name of the function, user can call
// option = parameter passed to the function
// Now check if id, key, function and option are requested and then
// call function if it exists.
if(isset($_GET['id'], $_GET['key'], $_GET['function'], $_GET['option']) {
$id = $_GET['id'];
$key = $_GET['key'];
if($id == '1234' && $key == 'secret_key') {
// define all functions here
function make_comment($option) {
...code for saving comment to database...
}
if(function_exists($_GET['function'])) {
$_GET['function']($_GET['option']);
}
}
}
?>
Then uesr can call this function from any button using simple call to the API, like
<a href='http://yoursite.com/api.php?id=1234&key=secret_key&function=make_comment&option=i_am_comment'></a>
