Display just child pages of a certain page in search results
StackExchangers!
I have searched the internet left right and center and still cannot find a way to alter the search results that are displayed. Basically I would like no posts and only child pages of this parent page to be displayed in the search results of my WP Site:
<
Otherwise, if none of these pages are displayed it would display null results.
Any help/direction is appreciated, I did try and gather as much information from here, forums and asking webdev friends - But I am completely stuck so I have resorted to asking StackExchange.
Hopefully this isn't too broad and you understand what I have been trying to figure out for days, otherwise if not, please ask for what you need and I can provide. | Try the following approach.
Get the page using `get_page_by_path()`
<
$page = get_page_by_path( 'university-guide' );

The following snippet was taken from Codex page: Creating a search form <
global $query_string;
$query_args = explode("&", $query_string);
$search_query = array();
foreach($query_args as $key => $string) {
$query_split = explode("=", $string);
$search_query[$query_split[0]] = urldecode($query_split[1]);
} // foreach
$search = new WP_Query($search_query);

How and when to include shortcode source files
I am Writing a plugin, with many shortcodes. Now I do not want to include all shortcodes source files to every page. So my questions are:
1. Where should I include the source? Is it back-end or front-end
2. How to add it on that specific page?
thanks HoGo | The pattern I use is:
* break code into modules using classes
* use spl_autoload_register() to load classes (thereby only included when used)
* have a class that is the plugin controller, with a method for each shortcode
* those methods generally do nothing but create instance of shortcode class and pass params
Works for me, simplifies things greatly, especially for large sites where I have dozens of classes. No need to carefully manage what gets included where because the class autoloader handles that. | stackexchange-wordpress | {

get_comments() where parent is not 0
I need a way to get just the comments that aren't top level i.e. where parent is not 0.
I've tried:
$args = array(
'parent' => -0
);
$comments = get_comments($args);

Translating long texts with html formatting
I was wondering what is the best way to translate some longer texts with html formatting. There was a couple of solutions I came across, but did not know what would be the best one.
* Writing a couple of html files with language extension (e.g. maintext_en.html, maintext_de.html, ...) and import this files.
_Pro_ : It's easy for me
_Contra_ : Not so easy for translators
* Writing only one html file with some markers and parse the file.
_Pro_ : A bit easier for translators, they have to edit only one file.
_Contra_ : I need a parser
* Using l10n inside the code
_Pro_ : The easiest way for translators
_Contra_ : Uses a lot of memory when the plugin runs. And the risk of losing some formattings.
What is the best and most efficient way to make long texts within a plugin translateable? | Most translation tools are really hard to use when you try to handle a long text, so the translators have to use a HTML editor anyway. Use separate files, but use the language prefix as directory name:
* en
* main.html
* help-main-options.html
* help-special-options.html
* de
* main.html
* help-main-options.html
* help-special-options.html
That’s easier to handle for translators and for you too.
You could also set up a WordPress site for translations and use a custom post type, so translators can use the regular editor (outdated example), and you handle just the import and export. | stackexchange-wordpress | {

Frontend tag edit/submit form
I would like to have a separate page to submit/edit tags.
Any user can edit or submit tags. But it should be published only after admin approval.
Is there any function available like `wp_insert_tag()`?
## Update:
After Kaiser's answer I've tried like this.
$x = wp_insert_term( 'test', 'post_tag', array('description' => 'This is a test tag') );
var_dump($x);
Its working fine. But it gets published automatically. Is it possible to publish it after admin approval? | In case that
1. I have understood your (very brief) question and
2. you're not actually talking about the `post_tag`-taxonomy
then you have `wp_insert_term()`, which is the underlying API function.
### Edit
As to the comment, there's the need of meta data for a term and administrator approval.
WordPress currently has **no** native way of adding meta data to a taxonomy taxon. There're ideas "around" it. _IMHO_ they clutter your DB-options table in seconds without a reason. There're other ways around this, but this would be too much for a single answer, so I can only recommend to find another way of handling tag maintenance. | stackexchange-wordpress | {

Which file displays the date archive?

Somebody who has a clue which it is? | `archive.php` is used to display author, search, category, tag and **date** archives. As clicking on a calendar day will take you to the date archive for that day, then the file you're looking for is `archive.php`.
More specifically, WordPress will check for these files in this order, stopping when it finds one of these files in your active theme's folder:
1. `date.php`
2. `archive.php`
3. `index.php`

How to delete ALL comments from certain category in Wordpress database?
I'm trying to delete all comments from posts in a certain category in a Wordpress database.
The Wordpress database is rather complicated so this must be probably some join of `wp_posts`, `wp_comments` and `wp_term_relationships` as the categories are not stored with neither posts nor comments.
How can I do this? I'm struggling to come up with a query. | The wordpress database seems fairly straight forward and is extremely well documented:
<
It seems to me that all the category information is stored in the table **wp_term_relationships**. So you should select from the comments table, join it with the posts table and then the term_relationships table in order to get the category for each comment.
Something like:
SELECT *
FROM wp_comments
WHERE comment_post_ID
IN (
SELECT c.object_id
FROM wp_terms a, wp_term_taxonomy b, wp_term_relationships c
WHERE a.name = 'my_category_slug'
AND b.term_id = a.term_id
AND b.taxonomy = 'category'

Passing variables trough 2 pages
I am creating a plugin. In this plugin I have shortcodes that provide some logic and content for pages. This way I have created 'Page A' and 'Page B'.

Wordpress Navigation default output

Getting term_id for newly created or edited term
I'm taking my first foray into plugin development and have got confused pretty quickly. I'm attempting to make a simple plugin that stores hex colours against terms, so you can assign a colour to a tag or category and then use that in a theme.
What I cant figure out is how to get the term_id of a newly created or edited term. I've bolted on a form to 'edit_tag_form' with a colour picker and can access these values through $_POST, but if it's a newly created tag I don't see how my code can know the ID of the newly created one. I need to know the term_id to be able to link it with the hex colour and save it to wp_options.
I'm using the action hook 'edited_term'. I guess for edited existing terms I could get the tag_ID from the query string, but I want to be able to assign colours immediately to newly created tags/categories. | Use the action `created_term`. Its first parameter is the `$term_id`.
It is called in `wp_insert_term()` in `wp-includes/taxonomy.php` after a term was successful created:
do_action("created_term", $term_id, $tt_id, $taxonomy);
do_action("created_$taxonomy", $term_id, $tt_id);
The second parameter is the term_taxonomy_id from the `term_taxonomy` table, and the last parameter is the taxonomy.
So register an action with …
add_action( 'created_term', 'wpse_78858_add_color', 10, 3 );
… and your callback should look like this:
function wpse_78858_add_color( $term_id, $tt_id, $taxonomy )
{

insert order number into wp ecommerce order confirmation email
A client site has been barred from using Paypal, so their WP-e-Commerce catalog/cart now has to use manual EFT bank payments to accept money from customers. A customer receives this banking information in their order confirmation email.
When a customer makes an EFT payment through their bank website, they have the opportunity to insert a reference to accompany the payment. This is a string of text.
We'd like to send the order number in the order confirmation email, so the customer can use the order number as the EFT reference, so the client site can match EFT payments and orders.
**How do we insert the order number into the order confirmation email?** | In the wp-e-commerce admin, Settings -> Store -> Admin, you can customise the Customer Purchase Receipt (confirmation email) template to add this, e.g.
`Please quote %purchase_id% as reference when paying by EFT.`
There are a couple of hooks in wp-e-commerce that let you insert other data into the confirmation emails:
* wpsc_transaction_result_cart_item -- this is called for each item in the cart array
* wpsc_transaction_result_message -- this is called to filter the text of the email
* wpsc_transaction_result_message_html -- this is called to filter the on-page confirmation

How is WooCommerce cart.php template supposed to be used?

How do I remove a category from a wordpress loop>
I have a question. I need to have, in my archive.php file, a exclusion of a specific category. given what I have now, how would I make that happen?
Here is the code:
<?php
query_posts(array(
'post_type' => 'post',
'showposts' => 5
) );
?>
<?php while (have_posts()) : the_post(); ?>
<div class="blogcontentlinks">
<a style="text-decoration:none;" href="<?php the_permalink() ?>"><h2><?php the_title(); ?></h2></a>
<p style="">Posted on <?php the_time('m/j/y g:i A') ?><br />Categories: <?php the_category(' ') ?><br />Tags: <?php the_tags(' ') ?></p>
<p><?php the_excerpt(); ?></p>
<p> </p>
</div>
<?php endwhile;?>
Thank you | You can add `category id` or `category slug` into arguments you are passing to `query_posts`:
<?php
// category slug ('products')
query_posts(array(
'post_type' => 'post',
'showposts' => 5,
'category_name' => 'products'
) );
?>
or
<?php
// category id ('3')
query_posts(array(
'post_type' => 'post',
'showposts' => 5,
'cat' => '3'
) );
?>
In the second case you can use comma separated list of category ids like `'cat' => '3,5,7'`. | stackexchange-wordpress | {

Create custom taxonomy and Display in metabox dropdown
I'm looking to create a dropdown in the post edit screen which contains 3 already existing tags. What's the easiest way of doing this?
Basically all I'm looking for is a simple drop down which adds one of the following tags to the post itself; 'beef-stew', 'pea-soup' & 'chili'. I'd also like 'beef-stew' to be the default.
Thank you in advance
EDIT: As I don't want the user to be able to display more than 1 of these 3 categories at any time, and have to option to easily change which one as they please, tags might not be the best solution?

Woocommerce product categories order
Is it possible to sort product categories?
I have a category with a lot of subcategories. On the category page all the subcategories is listed. Right now I can only change the order by drag and drop in the admin panel.

$i = -1;
foreach ($terms as $term) {
$i++;

How can I add a jQuery OnClick event to the Publish posts button?
I want to add a simple confirmation event to the Publish posts button, so when my client hits "Publish" it will ask him if he's sure, to which he clicks "Yes" or "cancel" and the post then publishes or doesn't.

add_meta_box('submitdiv', __('Publish'), 'post_submit_meta_box', null, 'side', 'core');
But to accomplish this, I suspect I'll need to add the jQuery code elsewhere - preferably in my theme.
For site-specific reasons, I cannot add new plugins to this installation so any changes need to be confined to my theme's `functions.php` file. | You can hook into the post footer actions (based on this answer, not tested):

function wpse_80215_script()

?>
<script>
document.getElementById("publish").onclick = function() {
if ( confirm( "Ready?" ) )
return true;
return false;
}</script>
<?php
}

Where are available Roles Defined in the wp_ database?

The thing is, whatever the layout I create, I'm very dependent of the default "fluid" layout of the admin.

Need help "sanitizing" a custom function that pulls category slug into body class

Register a title automatically with a relationship field
I'm trying to optimize the code of my site . I wanted to know if it was possible to give automatically a title to a new post without having to do it manually. I have a website of video games. Before posting a review, I first need to create the plug of this game with all the information (publisher, developer, pc configuration etc.).. So I have to put twice the same title. I would only select the plug of the game without having to type the title of the game
To get the title, I am able to retrieve the ID of the plug. Do you think I can write a function?
Thank You
Code example for get the title of a game :
<?php foreach(get_field('fiche') as $post_object): ?>
<? echo get_the_title($post_object->ID); ?><br />
<? echo 'Genre' .get_field('genre', $post_object->ID); ?>
<? endforeach; ?> | If you can grab your data early enough you can do this:
function alter_title($t) {
return 'altered-title';
}
add_filter('pre_post_title','alter_title');
add_filter('pre_post_name','alter_title');
That will change the title and the slug before the post is saved. Of course, you need to work out some logic for that function. As is, it changes all post/page/CPT names and slugs on both save and edit. Probably not what you want... :)
That should work. Your game data should be in `$_POST`. If for some reason it doesn't you can run a function on `save_post` but you will need to push another write to the database.
There are a lot of hooks for post insert/edits so you may even find something more appropriate by browsing the source file. | stackexchange-wordpress | {

strange behavior with comment position
I've created a custom `content.php` and removed any comments on the `content.php` page
then i changed the `sharing-service.php` from jetpack and added `comments_popup_link` there:
// Wrapper
$sharing_content .= '<div class="sharedaddy sd-sharing-enabled">';
$sharing_content .= '<div class="robots-nocontent sd-block sd-social sd-social-' . $global['button_style'] . ' sd-sharing">';
if ( $global['sharing_label'] != '' )
$sharing_content .= '<h3 class="sd-title">'. comments_popup_link( __( 'Leave a reply', 'changed2012' ) , __( '1 Reply', 'changed2012' ), __( '% Replies', 'changed2012' ) ) . $global['sharing_label'] . '</h3>';
$sharing_content .= '<div class="sd-content"><ul>';
and it looks like this:

How can i retrieve default post per page value? from settings->reading. And total number of posts?
I want to retrieve the default value of Post per page (the value that is set in settings->reading.
I've looked around and so far I've only found ways to query it. problem is i dont want to change what was set i just want to retrieve it for pagination purposes. i thought of using `$something->post_count.`(i might be wrong but as i understand it returns the amount of posts displayed currently) but this could be wrong in some cases.

Retrieving data from specific multisite blog

Wordpress login form script
I am looking for something very simple but I'm not quite sure how to achieve this. I have been researching for the past 2-3 hours and gathered a lot of useful information. However, my knowledge in both PHP and WordPress isn't enough to do this from scratch.

<a href="#">Login</a>
* When the user **is** logged in, the previous HTML code should be replaced with:
<span>Welcome, *username*</span>
<a href="actual-link-for-logging-out-the-user">Logout</a>
Could anyone please help me out. I'd really appreciate the help :)

Blogroll/Lins Menu not visible in my backend?

remove_menu_page('tools.php'); // Tools
//remove_menu_page('link-manager.php'); // Links
//remove_menu_page('edit-comments.php'); // Comments

Limit one submission from each user using Contact Form 7?
