In mediawiki, is it possible to change the label of a 'Category' at the bottom of an article.
For example for the following article:
=Paris=
blablablablablabla
[[Category:place_id]]
I'd like to see something more verbose like (the example below doesn't work):
=Paris=
blablablablablabla
[[Category:place_id|France]]
Note: I don't want to use a 'redirect' and I want to keep my strange ids because they are linked to an external database.
I do not think mediawiki is supporting this feature.
However, how about using:
[[Category:France]]
in your page, and set it into the category named with your id? France would just be a subcategory of "place_id", and you could use more terms all linked to the parent category. For this, you just need to edit the category page for "France", inserting:
[[Category:place_id]]
An alternative would be to put your page in both categories, but in this case, the id would still be displayed:
[[Category:place_id]]
[[Category:France]]
You could do this with an OutputPageMakeCategoryLinks hook. Alas, the interface for that hook seems to be a bit inconvenient — as far as I can tell, it's pretty much only good for replacing the standard category link generation code entirely. Still, you could do that is you want:
function myOutputPageMakeCategoryLinks( &$out, $categories, &$links ) {
foreach ( $categories as $category => $type ) {
$title = Title::makeTitleSafe( NS_CATEGORY, $category );
$text = $title->getText();
if ( $text == 'Place id' ) {
// set $text to something else
}
$links[$type][] = Linker::link( $title, htmlspecialchars( $text ) );
}
return false; // skip default link generation
}
$wgHooks['OutputPageMakeCategoryLinks'][] = 'myOutputPageMakeCategoryLinks';
(The code above is based on the default category link generation code in OutputPage.php, somewhat simplified; I assume you're not using language variant conversion on your wiki, so I removed the parts that deal with that. Note that this code is untested! Use at your own risk.)

There's this addition to the SQL WHERE clause on wp-includes/class-wp-query.php:1306:
<?php
// wp-includes/class-wp-query.php:~1306
foreach ( $q['search_terms'] as $term ) {
//...
$like = $n . $wpdb->esc_like( $term ) . $n;
$search .= $wpdb->prepare( "{$searchand}(({$wpdb->posts}.post_title $like_op %s) $andor_op ({$wpdb->posts}.post_excerpt $like_op %s) $andor_op ({$wpdb->posts}.post_content $like_op %s))", $like, $like, $like );
// ...
Therefore, I'd hook into the pre_get_posts, and supply the words of the query as explicit "search_terms", since they get added into that clause, with the LIKE modifier just as you said were looking for!
So, we might do something like this:
<?php
// functions.php
function fuzzify_query(\WP_Query $q) {
if (true === $q->is_search()
&& true === property_exists($q, 'query')
&& true === key_exists('s', $q->query)
) {
$original_query = $q->query['s'];
$words = explode(' ', $original_query);
$fuzzy_words = array_map(
function($word) {
return '%'.$word.'%';
},
$words
);
$q->query_vars['search_terms'] = $fuzzy_words;
return $q;
}
return $q;
}
add_action('pre_get_posts', 'fuzzify_query', 100); // Or whatever priority your fuzziness requires!
I'm new to web-design and in process of creating a sports website based on the WordPress platform.
One of the sports that the site will be covering is cricket. My site is almost done, but I'm stuck at few very important CSS/Html tables for data. I would really appreciate if someone here could guide/help me on how to create tables like the ones in the links bellow or whether there is anyway someone can copy html/css from an existing site and style it.
I just need a copy of the tables, sorting options are not needed
Similar scorecard as light as possible would be great
Are these things possible with CSS/html in Wordpress or is there any better option for such tables?
Here are two solutions you could use:
Solution #1: TabPress Plugin
Through a graphical panel, you can fully customize your table. You can set your own CSS, you can have colspan, rowspan or all together. Check out the demo. If you don't want to spend too much time in coding, give it a try.
Solution #2: WP_List_Table
It's available since WordPress 3.1. WP 3.1 uses it to build the tables you can see in the admin panel. The table who displays the posts for instance uses this class. However, you can disable some features such as sorting, bulk operations etc.
Here is a sample code taken from one of my blogs. I wanted to display a table of statistics with no sorting option. Call ff_show_stats() to display the table from your PHP code.
if( ! class_exists( 'WP_List_Table' ) ) {
require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
}
class FFStatsTable extends WP_List_Table {
function __construct(){
}
function get_columns(){
$columns = array(
'id' => 'ID',
'creation' => 'Creation',
'country' => 'Country'
// Add as much column as you want
// 'column_name_in_query' => 'Displayed column name'
);
return $columns;
}
function column_default( $item, $column_name ) {
switch( $column_name ) {
case 'id':
case 'creation':
case 'country':
return $item[ $column_name ];
default:
return print_r( $item, true ) ; //Show the whole array for debugging purposes
}
}
function prepare_items() {
global $wpdb;
$columns = $this->get_columns();
$hidden = array();
$sortable = array();//Empty array for disabling sorting
$this->_column_headers = array($columns, $hidden, $sortable);
$this->items = $wpdb->get_results(
"SELECT id,creation,country FROM wp_my_table WHERE my_condtion=TRUE",
ARRAY_A
);
}
}
function ff_show_stats() {
$myListTable = new FFStatsTable();
echo '<div class="wrap"><h2>Stats</h2>';
$myListTable->prepare_items();
$myListTable->display();
echo '</div>';
}

I have a project where users submit many links to external sites and I need to parse the HTML of these submitted links and extract basic information from the page in the same way that Digg and Facebook do when a link is submitted.
I want to retrieve:
main title or heading (could be in title, h1, h2, p etc...)
intro or description text (could be in div, p etc...)
main image
My main problem is that there seem to be too many options to explore here and im getting a little confused to sat the least. Many solutions I have looked so far seem to be inadequate or huge overkill.
You would pick a server side language to do this.
For example, with PHP, you could use get_meta_tags() for the meta tags...
$meta = get_meta_tags('http://google.com');
And you could use DOMDocument to get the title element (some may argue if needing the title element, you may as well use DOMDocument to get the meta tags as well).
$dom = new DOMDocument;
$dom->loadHTML('http://google.com');
$title = $dom
->getElementsByTagName('head')
->item(0)
->getElementsByTagName('title')
->item(0)
->nodeValue;
As for getting main image, that would require some sort of extraction of what may be considered the main image. You could get all img elements and look for the largest one on the page.
$dom = new DOMDocument;
$dom->loadHTML('http://google.com');
$imgs = $dom
->getElementsByTagName('body')
->item(0)
->getElementsByTagName('img');
$imageSizes = array();
foreach($imgs as $img) {
if ( ! $img->hasAttribute('src')) {
continue;
}
$src = $img->getAttribute('src');
// May need to prepend relative path
// Assuming Apache, http and port 80
$relativePath = rtrim($_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'], '/') . '/';
if (substr($src, 0, strlen($relativePath) !== $relativePath) {
$src = $relativePath . $src;
}
$imageInfo = getimageinfo($src);
if ( ! $imageInfo) {
continue;
}
list($width, $height) = $imageInfo;
$imageSizes[$width * $height] = $img;
}
$mainImage = end($imageSizes);
I need to amend (via CONCAT, presumably) something to every wordpress post if it belongs to a certain category (say, category ID 7), but I'm struggling to get it to work.
To test, I'm first trying to select all the relevant posts. So far, I have the following:
SELECT post_title
FROM cruise_wp_posts
LEFT JOIN cruise_wp_term_relationships
ON cruise_wp_term_relationships.object_id = cruise_wp_posts.ID
WHERE term_taxonomy_id = 87;
However, it only lists posts that are only in category 87 - I need all posts that are in category 87 (and possibly other categories too)
I'm a MySQL newbie, and this is really breaking my brain.
Any pointers would be passionately welcomed.
The best way to do it is to filter it in as needed. This way the addition is made everywhere the_content is used and not just in the templates you modify.
<?php
function my_content_concat($the_content) {
if (in_category(7)) {
$the_content .= '<br /><br />foo!';
}
return $the_content;
}
add_filter('the_content', 'my_content_concat', 9);
?>
in_category can take the id, name or slug of your target category.
I put the filter at 9 so that it runs before WordPress texturizes the content. If you don't need that run it at 11.
Why not just use get_the_category( $id ) and ammend the text when you output the post?
$cat = get_the_category( $postID );
if ($cat == 7) {
//Add text here
}
I have a website where members can input text using a limited subset of HTML. When a page is displayed that contains a user's text, if they have any unclosed tags, the formatting "bleeds" across into the next area. For example, if the user entered:
Hi, my name is <b>John
Then, the rest of the page will be bold.
Ideally, there'd be someting I could do that would be this simple:
<div contained>Hi, my name is <b>John</div>
And no tags could bleed out of that div. Assuming there isn't anything this simple, how would I accomplish a similar effect? Or, is there something this easy?
Importantly, I do not want to validate the user's input and return an error if they have unclosed tags, since I want to provide the "easiest" user interface possible for my users.
Thanks!
i have solution for php
<?php
// close opened html tags
function closetags ( $html )
{
#put all opened tags into an array
preg_match_all ( "#<([a-z]+)( .*)?(?!/)>#iU", $html, $result );
$openedtags = $result[1];
#put all closed tags into an array
preg_match_all ( "#</([a-z]+)>#iU", $html, $result );
$closedtags = $result[1];
$len_opened = count ( $openedtags );
# all tags are closed
if( count ( $closedtags ) == $len_opened )
{
return $html;
}
$openedtags = array_reverse ( $openedtags );
# close tags
for( $i = 0; $i < $len_opened; $i++ )
{
if ( !in_array ( $openedtags[$i], $closedtags ) )
{
$html .= "</" . $openedtags[$i] . ">";
}
else
{
unset ( $closedtags[array_search ( $openedtags[$i], $closedtags)] );
}
}
return $html;
}
// close opened html tags
?>
you can use this function like
<?php echo closetags("your content <p>test test"); ?>
You can put the HTML snippet through Tidy, which will do its best to fix it. Many languages include it in some fashion or another, here for example PHP.
This can't be done.
Don't let users invalidate your HTML.
If you don't want to let users fix their errors, then try to clean it up automatically for them.
You can parse the data entered by the user. Thats what an XML does. You may need to parse or replace the standard html or xml symbols like '<', '>', '/', '&', etc... with '<', '>', etc...
In this way you can achieve whatever you want.
There is a way to do this using HTML and javascript. I wouldn't recommend this method for public-facing websites; you should clean your data before it reaches the browser. But it might be useful in other situations.
The idea is to put the potentially invalid content into a noscript tag, like this:
<noscript class="contained">
<div>Hi, my name is <b>John</div>
</noscript>
... and then add javascript that will load it into the DOM. Using jQuery (but probably not necessary):
$("noscript.contained").each(function () {
$(this).replaceWith(this.innerText);
});
Note that users without javascript will still experience the "bleeding" that you are trying to avoid.
