Which contact form plugin passes Outlook junk / spam filters?
I'd like to know which contact form plugin has the best header and email creation so that Outlook does not filter it as junk mail. I'm using jigowatts simple php contact form. I am going to test the AJAX WP plugin version but would like to hear from everyone and what they use to get emails accepted by Outlook.
Thanks | Contact Form 7 is working well and no emails are getting filtered as junk in outlook | stackexchange-wordpress | {

How to filter out Categories for specific post types on Wordpress Admin?
How can i programatically change the Category selection menu on wp-admin? is there a hook or filter to edit the Category List?

under the post-types: People and Activities
I want to filter the Sports Category out of the People Post-type. | I went down the rabbit hole with this a few weeks ago. Never quite got it working right.

Create wordpress dashboard metabox which spans all columns
Is it possible to create a wordpress dashboard plugin that will span all the columns that the user has chosen to display? I know how to force the user to only display one column but I would rather leave them that freedom and span the number of columns that they have selected. Be it one, two, three or four. Thanks. | No you can't - a metabox cannot span more than one column, and so the width of the metabox is determined by how many columns there are. | stackexchange-wordpress | {

Including a post title in a twitter link
Im trying to make a Twitter button on each article of my blog. This is the code I use on single.php
<a href=" echo urlencode(get_the_title()); ?>">
Tweet this!
</a>
The problem is that I have a blog post with this title:
> Give format to “bodytext”
and when I tweet it, the quotes appear as
> Give format to “bodytext”
What should I do? | The problem is that `get_the_title()` will pass the title through a filter that texturizes the quotes. So a regular " becomes a curly quote (") and `urlencode()` will break it.
So instead, write your own title function and use that:
function my_get_the_title() {
global $post;
return $post->post_title;
}
This should bypass any unwanted filters and let you work with regular quotes. | stackexchange-wordpress | {

Where is wp() function definition?
In WordPress source code, there is one point I can not understand. In /wp-blog-header.php, there is a call to wp() function. However, I can not find any definition for that function. How this call don't cause error? | Just follow the code :).
Before calling `wp()`, `/wp-blog-header.php` loads `/wp-load.php` (which assuming you have correctly installed WordPress) loads `/wp-config.php`. At the bottom of that file, it calls `/wp-settings.php`.
This file loads a lot of other files, initialising the core parts of WordPress. Amongst them, is the `wp-includes/functions.php` file. It's inside this file that `wp()` is defined.
Once `/wp-settings.php` has finished loading all the files, `wp()` is then called - this 'starts' WordPress (interpreting the incoming url, processing it into a query, choosing a template and finally outputting the content and sending into the user. | stackexchange-wordpress | {

Navigation menu displays permalinks
I am creating a theme from scratch and the navigation menu is disturbing me because it is displaying the permalinks after the menu item name. See this picture
<
Link name (#permalink) is the result of `wp_nav_menu()`
Setting e.g. `$before/$after` \- yields text before/after (#permalink)
The (#permalink) part is not displayed in the source.
Since it's only Pages I tried wp_list_pages(), but that gives me the same result.
Any ideas on how to remove those permalinks? I believe there is some 'default' setting for how links/menu items should be displayed but I don't know where to look.
Thanks! | Since the (#url) isn't displayed in the source, I suspect this is being placed there by CSS with a rule like:
#menu a:after { content: "#"attr(href); }

How to define category ID in an array?
I have the following:
<?php if ( array( 'is_category', 'is_tag' ) ) { ?>
What I want to do is (that doesn't quite work):
<?php if ( array( 'is_category('13')', 'is_tag' ) ) { ?>
So what I'm asking is, how can I include that ID in code that will work? That's how I would do it anywhere outside of an array, so I am unsure exactly how to include it here.
Thanks | As Geert pointed out, your current conditional will always be true. An if() construct needs to be fed an expression. You're feeding it a valid array, so that's _true_. Always. So far this is basic PHP, regardless of whether in a WP environment or not.
As can be read in Chris_O's comment
if ( is_category('some-cat') && is_tag('some-tag') ) {
// do something
}
will do the trick.
`'some-cat'` and `'some-tag'` may be the category/tag slug, id or title. The codex page on conditional tags explains the use of these rather well. | stackexchange-wordpress | {

Post Ancestor and Child Post in Custom Post Type
!enter image description here
Hierarchical structure of custom post type "Book" (for example).
When we are on `Post 2-95`, I want to know:
* Does the post has this post ancestor(`Post 1-31`)?
* Does it have child posts(`Post 3-19`, `Post 3-10`)?
Then, if it has:
* an ancestor post: retrieve (object) of this post.
* a child posts: retrieve (objects) of these posts. | Given a post represented by a post object `$p`, you can find out if post 31 is the parent via:
if($p->post_parent == 31){
// it is!
} else {
// it isn't
}
To figure out the children, something like:
$posts = get_posts(array(
'post_parent' => $p->ID,
'post_type' => $p->post_type
));
// if there are children, they will be contained in `$posts`
Finally, to determine how many levels deep down the hierarchy you are, you will need to recurse up the hierarchy `$p->parent_post == 0`, and then count how many times you needed to do that.
e.g.
$level = 1;
while($parent->parent_post != 0){
$level++;
$parent = get_post($parent->parent_post);

Using a menu walker add a custom item at the end of the menu's items
I need to add a search field at the end of a menu in a list item.
I've been looking at walkers but finding it really hard to figure out what is the last item (or even get the total). Also where would i add the code for the custom item.

//print_r($item);
$output .= $this->custom_content( $item );

}
protected function custom_content( $item )
{
// add <li>SEARCH FIELD HERE?</li>

Remove "minor-publishing" div from Publish admin metabox
I want to remove the `#minor-publishing` `div` from the Publish admin metabox. I came across How to HIDE everything in PUBLISH metabox except Move to Trash & PUBLISH button and < but they either remove it by css or custom-code their metabox.
Is there a way to remove the div by hooking on to some action and modifying the html that will be outputted for that metabox?
How to Move the Author Metabox into the "Publish" metabox? modifies the html output by _adding_ code to it. What I need is to _remove_ the entire `#minor-publishing` `div` from the html that will be output for the Publish admin metabox.
Thanks in advance. | In short- no. The html in question is hard-coded in the `post_submit_meta_box` callback function.
You can, of course de-register the publish metabox and re-register your own which mimics `post_submit_meta_box` (but making your alterations) and being sure to keep the names of the inputs exactly the same. This method has been outlined the following posts where a core metabox is required to be edited.:
* custom post type taxonomies UI radiobuttons not checkboxes
* Custom-Taxonomy as categories: Remove "most-used" tab?
It's a lengthy function though - and would break if core ever changed decided to change the names of the inputs (though very unlikely).

Hide root site in Multisite install
I recently setup a WordPress multisite install using subdomains and the WordPress MU domain mapping plugin.
When I initially setup the domain mapping plugin, I set the root ( and < to redirect to blog ID 2 (ie. www.domain.com). However, when I do this the redirect on the root prevents me from accessing the Network admin page.
Is there a way I can change the configuration to enable me to still access the Network admin page whilst redirecting the root site to www? | I was in a similar situation recently. I ended up putting the root site on a random subdomain (eg `ms.domain.com`) With the intention of never using the root site.
With that done, I created a plugin to activate only on the main (root) site.
The plugin hooks into a action that fires only on the front end (`template_redirect`). From there, call `wp_redirect` to send your visitors to where they need to be.
<?php
add_action('template_redirect', 'wpse52298_redirect');
/*
* Redirects all requests to the front end to another site
*
* @uses wp_redirect
*/
function wpse52298_redirect()
{
// change this
$to = '
wp_redirect(esc_url($to));
exit();
}
**Cons:**
* Loads basically all of WP before redirecting
* Not as fast as redirecting in htaccess
**Pros:**
* Easy to maintain
* No htaccess foo required

get attachments for all posts of particular post type

WP_Query pagination using only numbers instead of /page/1 on URL
I don't get whats happening here.
I'm on a child-page template, generating a WP_Query for Custom Post Types on the fly, like this:
$notrel = new WP_Query(array(
'post_type' => $type,
'posts_per_page' => $perpage,
'monthnum' => $mes,
'year' => $ano,
'paged' => $paged
));
Loops and $_GET filters for `post_type`, `monthnum` and `year`are all working perfectly. But pagination is giving me trouble.
A) If i try the URL ` i get `paged = 1`.
B) On the other hand, ` correctly gives `paged = 4` but pagination doesn't work since `next_posts_link` automatically shapes URLs like A.
I guess `/page/4/` is standard, so why is it not working here? Is it maybe the rewrite parameter on register_post_type?
**EDIT:** still not solved, se this -> paginate_links() adds empty href to first page and previous link | I didn't really solve it, but got around with the help of Passing custom args in paginate_links and Custom paging function.
Initially I even thought of writing a patch to `next_posts_link`, but as it turns out, the URL formatting problem lies way below in the function soup, and that is really a downer when all I wanted was to reuse some earlier code that went into this template when it was still static.
My solution for now was to leave it all behind and start fresh with `paginate_links()`. Turns out that paginate_links doesn't care about permalink structure and always appends `?page=4` to the URL which just makes a lot more sense. :)
UPDATE: Followinfg along, I got this problem -> paginate_links() adds empty href to first page and previous link which was properly solved after all. :) | stackexchange-wordpress | {

How to pull a list of posts in a category while exluding posts in subcategories of the category

How can I exclude subcategories from the query?
$cat = get_query_var( 'cat' );
$catHidden=get_cat_ID('hidden');
$args = array('cat' => "$cat,-$catHidden");
$myposts = get_posts($args); | If you use `category__in` and `category__not_in` instead, it will only pull the posts that are in that category, not the subcategories as well. For your code, this would look something like this:

'category__not_in' => $catHidden
);
Note: this will only exclude posts that are directly in the category as well. If you want to exclude posts in that category and the subcategories of it, use `cat` with the negative syntax.

Archive pages have smaller font then the rest of my website

In fact, Woo adds two new buttons to your WYSIWYG editor to insert the shortcodes for you! This wouldn't be a very good standalone plugin if it required theme editing just to function. While you can hook directly into the theme, it's not necessary - nor is it really advisable, since you may want to change themes without rewriting all your custom hooks. | stackexchange-wordpress | {

displaying tags in a widget
I have a widget which displays the latest projects as thumbnails on my website. When I mouse over a thumbnail the project title appears; this is the code for title:
`<h2><?php echo get_the_title(); ?></h2>`
So, I'm thinking to display also the tags from that specific project, to be something like beautiful, nature, landscape
Is this possible, or could you give me some suggestions on how to achieve this ? Thanks! | By what code you've posted, it seems like you've got a secondary loop set up (using a `WP_Query` object). So to display the current' posts tags you can use:
* `the_tags` \- to print a list of the post's tags
* `wp_tag_cloud` \- to print a tag cloud.
* `get_the_tags` \- to return an array of tag objects, which you can then use to display the tags however you'd like. | stackexchange-wordpress | {

Is there a way to separate wordpress titles from their posts?
Basically I am coding my own theme, and I would like to have my titles listed on the left hand side, so that on clicking the title, the corresponding body opens up on the right. How can I list these two interlinked items separate from each other, but still have the title reference the right post. The problem I'm anticipating is that I might have to construct a different loop for the titles section and the body section each. Once I've done this, I don't see how I can link them together so that the jQuery I use would link the title to the corresponding body.
Much thanks in advance | **Here is an idea:**
1. Use `get_posts()` to get posts you want.
2. On the right hand side show titles via `foreach`.
3. use `setup_postdata()` on right hand side loop to get post content.
4. You can use jquery tabs to show and hide post content or just use jquery.
5. Don't do `get_posts()` twice or use ajax because you already got contents when you did `get_posts()` on no. 1
**How do you relate contents:**
So you have content of same posts on two part of the page. How do you relate them to use on jquery. Well, you can use post id off course. Check for same id on the content area if id matches with title show the content.
<h1 id="post_<?php the_ID(); ?>><?php the_title(); ?></h1>
...
...
<div id="post_content_<?php the_ID(); ?>>the_content();</div>

Different fields in My Profile page depending on user role
So I understand that I can user current_user_can to check the role of the current logged in user. But what I would like to do is show these different fields to the site Admin.

How to get 4 Posts after the 5 most recent ones
Well, I think the question might be a bit confusing. But well, I want to get the recent 4 posts, ignoring the first five recent posts. So in short the sixth, seventh, eighth and ninth - most recent posts. | Simple.
WordPress provides a function called `get_posts()` that lets you get posts in any order. Basically, `get_posts()` will retrieve the 5 most recent posts by default.
To get 4 posts, ignoring the 5 most recent, you'd set the `numberposts` and `offset` parameters - `offset` tells the function how many posts to skip.
$args = array(
'numberposts' => 4,
'offset' => 5,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish'
);
$posts = get_posts( $args );
Now you have an array of posts the 4 latest posts (ignoring the 5 most recent), ordered by date. | stackexchange-wordpress | {

Should I escape wordpress functions like the_title, the_excerpt, the_content
I had look at the code but I couldnt see any escaping on funcions like `the_title` `the_content` `the_excerpt`etc. I might not be reading it right. Do I need to escape these functions in theme development like:
`esc_html ( the_title () )`
Edit: as pointed out in the answers below the above code is wrong regardless - the code should have read `esc_html ( get_the_title () )` | Escaping depends entirely on the context in which you are using the functions. What is safe for displaying inside `<h1>` tags, is not necessarily safe to display for the `value` attribute of an input field, and even that wouldn't necessarily be safe as a `href` attribute value....
In short - perform the sanitisation yourself as you output it. Though in the case of `the_title ()` or `get_the_title ()`, `esc_html` is not necessary, since WordPress applies the following functions:
* `convert_chars`
* `wptexturize`
**Note:** `the_title` prints the title - so `esc_html ( the_title () )` won't work. Similarly, `the_content` prints the content (in any case, you'd expect the content to display HTML). | stackexchange-wordpress | {

Posts Page Featured Image

$page_for_posts = get_option( 'page_for_posts' );

<?php
$page_for_posts = get_option( 'page_for_posts' );

I'm trying to get a feed for pages and a separate feed for posts. The feed for posts works perfect as it is.
I just want a separate one but i have tried all the plugins and searched for about a week straight and still could not find a solution
Is it possible to take feed-rss2.php and duplicate it to change the code to include pages instead of posts and call it by `?feed=my_custom_feed`?
EDIT BELOW:
<
This is the script that I am using get the `<link>` tag from the item RSS. I want the pages to have an RSS feed unless anyone knows a different way of doing it without RSS. But the script above rotates the page every 30 seconds. | Feeds for post types are called with `feed/?post_type=POSTTYPE`. For no obvious reasons this doesn't work for the post type `page` – you get the posts instead.
But there is a filter to fix that: `'pre_get_posts'`. Let's use it:
add_action( 'pre_get_posts', 't5_pages_in_feed' );
/**
* Set post type to 'page' if it was requested.
*
* @param object $query
* @return void
*/
function t5_pages_in_feed( &$query )
{
if ( isset ( $_GET['post_type'] ) && $_GET['post_type'] === 'page' && is_feed() )
{
$query->set( 'post_type', 'page' );
}
}
Now you get the page feed at `/feed/?post_type=page`.
Here is a plugin for that: T5 Page Feed | stackexchange-wordpress | {

My title won't update

using custom fields on content.php file of my theme

You're better off just checking for the boolean, like above. The `get_custom_field_value` function already takes care of making sure you get something back.

How to create a child/addon plugin

$iteration = $iteration >= count($classes) ? 0 : $iteration;

What characters are allowed as a shortcode tag and how should they be sanitized?
I am working on a plugin where the user can define shortcode tags himself. What would you suggest to allow in there? My thought is only allow ascii characters.
So how do I sanitize? `strip_tags` and then regex to allow only `a-z, 0-9` or is there a better solution? Does WordPress have filter for that? Could I maybe use the filter WordPress uses for slugs?
thanks for the answers i will just do this, if there must be one ascii char anyway then i just require three.
foreach ( $shortcodes as $key => $var ) {
$var = preg_replace('/[^a-z0-9_]/', '', $var ); // strip away everything except a-z,0-9 underscore
if ( strlen($var) < 3 )
continue; // if less then 3 chars AFTER the strip don't save | You can use almost every character. Just the character `/` is dangerous. Do not allow it. WordPress is using `preg_quote` to escape the shortcode name, but it doesn't include its own regex delimiter `/` when doing that. So the shortcode will not be properly escaped and you get a PHP warning.
Besides that, there are just two basic rules for a shortcode name:
1. It should be at least two characters long.
2. It should contain at least one US-ASCII character (`a-z0-9`).
So this works:
foreach ( array ( '.-o', ']b', 'äoß', 'o"o', "o'o", 'm' ) as $shortcode )
{
add_shortcode( $shortcode, 't5_crazy_shortcode_handler' );
}
function t5_crazy_shortcode_handler( $attrs = array(), $content = NULL, $shortcode )
{
return "<pre>\$shortcode: $shortcode\n\n\$attrs\n"

I'd like to add the class `menu_element` to `li id="menu-item-30"` and every child li of the parent ul after. Is this possible?
Thanks in advance! | Check out the section titled Adding Conditional Classes to Menu Items on the `wp_nav_menu` Codex page. This should give you a pretty good overview for adding classes to menu items using the `nav_menu_css_class` filter.
For what you asked to do, which is add `menu_element` to the class attribute for both the menu item with ID 30, and the menu items listed after it, you could do something like this in your theme's `functions.php` file:
function menu_element_class($classes, $item){
if($item->ID == 30 || $item->menu_item_parent == 30) {
$classes[] = "menu_element";
}
return $classes;
}
add_filter('nav_menu_css_class' , 'menu_element_class' , 10 , 2);
This just checks to see if the menu item has an ID of 30, or has a menu_item_parent of 30, and adds "menu_element" to the classes array. Of course, you can change the `if` statement to check for whatever conditions you'd like before adding the class. | stackexchange-wordpress | {

Wordpress - Admin Manage Posts - Multiple Filters by Parent Category
Lets say I have the following Categories in Wordpress:
Product Category - Cat A - Cat B - Cat C
Service Type - Service A - Service B - Service C
On the Manage Posts page on the Admin side, I want to have 2 drop down filters for both Product Category, and Service Type, so I can filter by both on the backend.
How can I do this? | I'd say it's quite a huge task to split the default taxonomy in two dropdowns. Maybe some wizard stumbles upon your question and enlighten us...
The biggest problem I see is the split itself, because you can modify the query `&cat=1` to `&cat=1,25` so as to list two categories (by their id's).
What I suggest is creating a custom taxonomy for dealing with either Products or Services. And leave the other in the default categories.
And then apply the solution I linked in the comments to the question.
This way is easy to have two dropdowns and do the custom filtering you're looking for.
Just tested and it works.

Child theme grabbing wrong location fo parent theme files
I purchased a Wordpress theme this week, and to keep my changes separate from the original theme, I created a child theme for it. Right now it's just a barebones child theme, the style.css file and screenshot. The parent theme has several CSS and jQuery scripts that it includes. The problem however is that the child theme looks for these files in the child theme directory, rather than the parent.
For example if I am using the parent theme the location would be:
ParentTheme/js/jquery.easing.js
However in the child theme, it looks for the files here:
ChildTheme/js/jquery.easing.js
Rather than the parent theme like I would assume.
I tried copying the CSS and JS folders, but that didn't work either.
Am I doing something wrong? How would I use a child theme for a parent theme that has several CSS and JS files that are needed?
You can take a look for yourself here if you would like: < | As this is a commercial Theme, you really need to contact the developer for support.
That said: the Theme appears to be mis-using **`get_stylesheet_directory_uri()`**, when it _should_ be using **`get_template_directory_uri()`**. | stackexchange-wordpress | {

Ajax call to transients
If I make an ajax call to a Wordpress transient, is the transient value taken from memory on the server or is a call to the database made?
I'm not using any caching plugins.
My application is fetching a tag list. The frontend will display matching tags as the user types. I'm assuming that all transients are loaded when the page loads. And therefore that the transient is fetched from memory when the ajax call is made. Yes? | Without object caching plugins transients are stored using options API and, if set to expire, they have auto-load disabled. Meaning:
1. First request to transient needs to fetch it from database.
2. Subsequent requests will get data from memory.
However note that "memory" here is memory space of **single specific page load**. It's not shared and not persistent.
Ajax request performs new network request to site, loads new instance of WP core and does the stuff. It's quite heave operation, which is hard to optimize and it's performance impact overall makes transient API overhead irrelevantly small. | stackexchange-wordpress | {

How can i maintain permalink structure and avoid a 404 error when loading external content?
I created a page called Catalog and also a template called page-catalog.php. The url looks like this now: sitename.com/catalog
So far so good, however i use some custom php stuff to list products from another database. So when i click on a brand in this page, i want to use an url like this: sitename.com/catalog/brands/brandname
But obviously because the data is not coming from Wordpress, it gives me 404. Is it possible to use the same page-catalog.php file if the url has more parts?
I could use an url like this: sitename.com/catalog/?brand=brandname But this solution is not so sep friendly. | You could use a WordPress rewrite (as opposed to mod-rewrite) to solve the issue.
function createRewriteRules( $rules ){
$newrules = null;
$newrules = array();
$newrules["catalog/?$"] = "index.php?page=xx";
$rules = $newrules + $rules;
return $rules;
}
add_action('rewrite_rules_array', 'createRewriteRules');
You'll need to flush the rules:

Issue with RSS Feed in Firefox and Safari
The feed for a site ( shows fine in Google Chrome, but in Firefox and Safari it gives errors.
I've tried clearing the cache, but that doesn't solve the issue.
Any idea what could be causing the problem? | This isn't a WordPress issue.
An RSS feed is an XML document created by your server for end users to consume updates or changes through an RSS reader. **_A web browser is not an RSS reader._**
Every browser will handle an RSS feed differently - and they'll do even stranger things if they don't recognize it as XML.
Often, Chrome will see the feed and render it as a regular XML document - Chrome includes special parsers that clean up and format the display of an XML document to make it easier to read.
Firefox and Safari both see the feed and recognize that it's an RSS feed. Each of these browsers actually has a mini feed reader built in, so they'll try to parse the feed _as a feed_ and will display it very differently than Chrome.
If you see errors, it's likely a problem with the markup or encoding that prevents the browser from recognizing the file right away. If you want to _really_ test your feed, use an actual reader (i.e. Google Reader). | stackexchange-wordpress | {

Plugin to set all Posts in a certain Category to a certain Post Format
I want to setup my WordPress so that whenever I create a post with the category "Tweet", my wordpress installation automatically changes the post format from post to aside. This will help me because I want to use my wordpress for posting longer than 140 tweets to my twitter feed. The posting to twitter has been setup and it works.
The problem is that the Wordpress iOS app doesn't allow me to change the post format to Aside, so the only thing I can do is set the category of the post to "Tweet" and as soon as my wordpress receives it, it changes the post to aside.
I found the plugin "Set Aside" but it lets me change the post formats for all posts of a certain category that have already been posted, not the ones that I will post in the future.

I need to edit a list of quotes. Every quote consists of a (short) text, author's name, author's title.
What is the best way to create an editor of such data in WordPress?

If not with post types, then how?
Note, that I need two lists of quotes (in two languages). | I would build a custom post type. Use the editor to hold the quote in the site's default language and create a new box to hold the translated version. A second meta box can hold the author's name and title.

What is the problem ? | Probably because your sizes both have the same width, and you have it set to "proportional crop", which won't necessarily crop to your _exact_ dimensions. (See the Codex)

Output HTML only on individual post view

Custom Post Type URL Rewriting?
I setup a custom post type for my portfolio projects. The main URL for this is located at `/projects/`
Now I've also setup my blog posts permalink to `/articles/*/` for the permalink structure. This means when I go to view a portfolio project the URL changes to `/articles/projects/project-name/`
I know there must be a way to rewrite permalinks **only** for my projects custom post type. But I'm unfamiliar with the syntax in declaring the URL slug - would appreciate any help I can get! | When you register the custom post type, you have to specify that the rewrite rule shouldn't be prepended with the existing URL structure.
In short, this means that this line in your `register_post_type` call:
'rewrite' => array('slug' => 'projects'),
should turn into this:
'rewrite' => array('slug' => 'projects','with_front' => false),
For more info, check out the `rewrite` argument from the codex entry on `register_post_type`
_edit: just make sure that, after updating the code, you flush the rewrite rules by visiting Settings > Permalinks. Otherwise you'll still see the old links._ | stackexchange-wordpress | {
