Is it possible to enqueue a raw CSS string directly from within a template file?
I was wondering if it's possible to enqueue raw CSS as a string directly from within a template file?
I'm writing a custom template for a page and need to add some style rules for it. What I want to do is write the styles out as a string var in PHP then use the enqueue_style function to load these styles, rather than me having to add them in to 'style.css' or some other external style-sheet.
I assumed that so long as I enqueue my styles before calling the 'get_header' function, and if I hook in to the 'wp_head' or 'wp_enqueue_styles' actions, that this would work but it doesn't appear to and I'm not sure if 'wp_enqueue_style' can take a raw CSS string.
Anyone got any advice please?
Kind regards,
Chris | Yes and no.
You _can_ load a raw CSS string into the header programatically, but you can't use `wp_enqueue_style()` to enqueue it. That function specifically loads _files_ into the header in `<link>` tags.
But what you can do is something like this:
function print_inline_script() {
?>
<style type="text/css">
/* ... styles go here ... */
</style>
<?php
}
add_action( 'wp_head', 'print_inline_script' ); | stackexchange-wordpress | {

After moving my site from a dev subdomain, to root, all my custom meta data is gone
I just movde my site from a dev subdomain, to the root. I have extensive amounts of data saved in custom meta fields which I created with the WpAlchemy class. All of this data is not appearing in the site (back or front end), although it appears to be in the database.
This happened right after attempting to use the search replace plugin to change any lingering urls. This attempt ended in `Fatal error: Out of memory`. I noticed everything was gone, so I swapped out the db for my backup (after doing a manual search-replace for my subdomain). This produced the same result.
I think I've read somewhere that data serialization (am I getting this right?) can mess up this kind of thing. Is that whats happening to me here?
What steps should I take to get the site up and running ASAP. Currently it is live, and terribly broken :-( | Been there done that. Try this: < Its a search and replace tool that you put in your WordPress root and just run it from mydomain.dev/searchreplacedb2.php

Multilanguage Post Titles not Translating with List Category Posts Plugin
For the most part the plugin List Category Posts works great.
I just have one problem with it: when I try to show the title and excerpt of a post it shows all translations at the same time, rather than just the translation relative to the selected languages.

if ( function_exists( 'qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage' ) )
{
$single->post_title = esc_html(
qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage( $single->post_title )

How to run WP_Query to retrieve attachments to posts only from a particular category?
I have a WP blog with a few pages and posts and several categories. I want to write a loop to retrieve images attached to the posts (not the pages) and only those from a specific category and it's children. The category id is 60.

if get_post_meta is empty do something
I need opposite of this:
<?php if ( get_post_meta($post->ID, 'price_list_category1', true) ) : ?>style="display:none;"<?php endif; ?>
In other words I want `style="display:none;"` only when meta data doesn't exist.
I thought it would be straightforward like `if ( get_post_meta($post->ID, 'price_list_category1', true` but this true/false turns out to be a completely different stuff.
any ideas?
Thank you. | ~~You could use the`empty` function inside your `if` as such :~~
<?php if( empty( get_post_meta( $post->ID, 'price_list_category1', true ) ) ) : ?>style="display:none;"<?php endif; ?>
The above returns an error, you should assign the return value to a variable. See my edit below.
**Warning**
`empty` might not be the best option depending on the values you store in the meta. Values like `false`, `0` etc... will be considered empty.
Check the PHP manual for the full list of values that are considered empty.
**Edit**
You can try assigning the meta to a variable, and using that in the `if` statement.
<?php
$price_list = get_post_meta( $post->ID, 'price_list_category1', true );
?>
And then...

Serving Cookies From A Different Domain or Sub-Domain
The WordPress Codex clearly states that if your website is served from `example.com`, for the sake of performance, you can have the cookies served from `www.example.com` by adding this to your wp-config.php:
define('COOKIE_DOMAIN', 'www.example.com');
**Problem:**
* The cookies are still being served from `example.com` and not `www.example.com`. What's wrong? or does this no longer work?
_**PS:** Edited to be precise._ | Looks like I mis-interpreted what's said in the codex. So, here's the thing...
This is what WordPress does by default: `define('COOKIE_DOMAIN', '.example.com');` — which means, cookies are sent with all the sub-domains, including `example.com` itself, even if your WordPress website itself is hosted on `www.example.com`.
Basically the point is, when your WordPress site is served from `www.example.com`, you can also have the cookies sent only with `www.example.com` and not other sub-domains, by adding this in your wp-config.php:
define('COOKIE_DOMAIN', 'www.example.com');
So, at most, what the aforementioned code does is restrict the cookies to the sub-domain that serves your WP site.
**NOTE:** And just in case it's not clear -- it's pointless to use `define('COOKIE_DOMAIN', 'www.example.com');` when your site itself is served from `example.com` or some other sub-domain, and not 'www.example.com'. | stackexchange-wordpress | {

images in wordpress themes
I am developin a theme in php using wordpress.I want to display images on the website . so my question is what will be the best practise
1)store the image itself in a table using an "image" or "binary data" data type of the database server.
or
2)store the images as a file in the file system and create a record in a table with the exact path to that image. ..trying to bother the database as little as possible... . | Its never a good idea to store binary data in your database, take a look at this post: < and this post: <
In my opinion, its far faster to use the file system and here's why:
The image URL can be stored in a custom field by wordpress - this is very simple to do. The same representation of that image stored as binary is far larger than the image URL, therefore somewhat slower to fetch. You would also have to specifically write the code to do this.

Make WordPress process admin group comments using $allowedtags
WP uses `$allowedtags` to limit the set of allowable tags for comments.However, comments from administrators are unfiltered.
What's the easiest way to ensure admin comments are also constrained to the tags contained in `$allowedtags`? | `kses_init` is hooked onto the `init` hook with default priority, and (after first removing any of the kses filters) adds filters which strip out tags (`wp_filter_post_kses` for posts and `wp_filter_kses` for comments) if the user does not have the capability 'unfiltered_html'.
Since the capability determines whether or not the user can post 'unfiltered_html' comments _and_ posts - you probably don't want to just remove that capability.
Instead, hook onto `init`, _after_ `kses_init`, say with priority 20, and re-add the filters which strip out tags not in the `$allowedtags` whitelist:
add_action('init','wpse56687_filter_everyones_comments',20);

Faking the "onSave" event
While a specific use-case, I believe this may benefit others.
I am using TurboCSV to mass-import a number of posts into WordPress (which it is doing wonderfully so far). Within that import, I am specifying custom fields to be used in conjunction with Advanced Custom Fields to store/output the data. The post_meta table is being created correctly, but the part that is not working as expected is generating ACF's hidden fields (which work with field relationships). When the import is first done, those database tables are not created until you manually go into each post and re-save them. I was wondering if there is a way to "fake" the onSave event for WordPress for a number of posts. ACF also passes along post information (stored on the post edit screen) to this save function - which makes it a bit trickier - but I'd be interested if anyone has any thoughts. Thanks! | Have you seen wpshell? It's a command line tool for wordpress. Basically, it's a Wordpress environment that lets you run arbitrary php - so you could set up a `WP_Query` that pulls all posts, loop through them, and fire that command on each one.
Sort of what I had in mind, untested. Using `wp_update_post()` as it contains the `save_post` hook, and is the equivalent of hitting 'update' on the post edit screen:
$args = array('posts_per_page' => -1, 'post_type' => 'any')
$query = new Wp_query($args)

Date based CSS/theme
Is it possible to set a CSS stylesheet or a theme for articles that were published before X date?
The reason I ask is that we've just redesigned our website and some pages have images that are wider than the page size now. | I php you can create an anchor class based on the desired date. I haven't tested it, but it should be something like this:
// your relevant html parent element
<div class="<?php echo getOlderPostsClassName( '5/5/2012',the_time() ); ?>">
function getOlderPostsClassName($untilDate, $wordpressPostDate)
{
$start = strtotime($untilDate);
$end = strtotime($wordpressPostDate);
if ($start-$end > 0)
{
return 'My_css_class_for_older_posts';
}
else
{
return '';
}
}

How to save media-form on custom tab

WordPress in Drupal

Can someone (Support of my themeprovider) get access to my server If I send them my admin login?
I have bought a WP theme from a huge provider (themeforest). But it has a lot of bugs. The support asked me to send my WP Admin Login/Password. What risk does this have?
I know the supportstaff will have full access to the WP installation, with the WP admin credentials. this is ok for me.
But what about the server this instances is running on? Are there any changes that they would theoretically get access to the server? This is a no-no. As the sever hosts a lot of confidential stuff.
My Guess: Most likely yes, they could get access? (As far as I can tell they could input some php code in the wp-code-editor that opens up a shell or reads some files in the system?) Or am I wrong?
thanks! | If you give the provider full admin, they can technically do anything to your server that PHP would be able to do (by using the editor part of a given theme to add whatever commands they like). PHP is capable of running command line scripts, just to name one scary permission they would inherit.
Depending on what user (on the server, not in your WordPress install) you have running page scripts, that could be complete control or just control of some web portions of your server. Either way, it would not be insignificant.
I can't think of anything beyond the theme editor that would put your server in danger, but if they are providing the theme, I would think they would need access to that in order to do much so I don't know that there's a good option for you to keep your server safe and give them what they're asking. | stackexchange-wordpress | {

}
global $post;
if($post->ID == 11746){ // Load slider on home page
add_action('wp_enqueue_scripts', 'load_slider');
} | method two won't work because no page is loaded yet and $post isn't set when your if check runs.
with method one again $post is not yet set at that point, but this method will work if you use WordPress conditionals:

WP Multisite development with Mamp Pro and wildcard subdomains, not really working for me
I´m trying to set up a local development environment for me to work on a Wordpress multisite that I´m building.

I just started working locally with Wordpress. Trying to update theme/plugins I get asked for my FTP credentials and I get really confused...what the heck is my FTP credentials when working locally? | **Set file permissions**
On Mac OS X (Leopard), the Apache HTTP Server runs under the user account, _www which belongs to the group _www. To allow WordPress to configure wp-config.php during installation, update files during upgrades, and update the .htaccess file for pretty permalinks, give the server write permission on the files.
One way to do this is to change the owner of the wordpress directory and its contents to _www. Keep the group as staff, a group to which your user account belongs and give write permissions to the group.
$ cd /<wherever>/Sites/<thesite>
$ sudo chown -R _www wordpress
$ sudo chmod -R g+w wordpress

How does printf( __( ) ); work?

<?php
printf(
__('Designed by %s', 'Anyword'),
'<a href="

Can someone exactly explain this line for me? | It's used for translate text.
The second argument is a kind of namespace (called domain here) to retrieve the translation (for example from a dedicated file or something else).
So `Anyword` here, should be the guy behind the template, or the company or what ever that can be a domain/namespace.
**edit:**

* * *
Add this to the Plugin code to make sure the language file(s) are loaded:
load_plugin_textdomain('your-unique-name', false, basename( dirname( __FILE__ ) ) . '/languages' );
To fetch a string simply use `__('String name','your-unique-name');` to return the translation or `_e('String name','your-unique-name');` to echo the translation. Translations will then go into your plugin's /languages folder.

Using wp-super-cache and amazon cloudfront - can I serve a file directly (no cdn)?
I'm using the wp super cache plugin with cdn support turned on (aws cloudfront). I'm also using wp tables reloaded. The latter plugin includes a text file via ajax, and that file is being served by the cdn. The plugin doesn't do any sort of jsonp maneuvers, so the file hits access-control-allow-origin issues.
Before I go and mess with the plugin to pull the file correctly, does anyone know how I can restrict the cdn from storing this file, and just serve it up directly? | The CDN tab of wp-supercache allows you to exclude files and folders.
[edited to add]
The field `exclude if substring` allows entry of a comma separated set of strings (eg `.php, wp-include, specialpluginjsfilename`). Any file names that match against this set of values is excluded from the CDN.
So, using the example above the following would be excluded from the CDN

* Any files or any file from any directory that has the string `wp-include` in it
* Any file or any file from any directory that has the string `specialpluginjsfilename` in it. | stackexchange-wordpress | {

Ability to edit image via WYSIWYG
In the wordpress post WYSIWYG, you can easily add images from the media library. But, once the image is inserted into the post, it is not intuitive to edit the image's source to a different image in your media library. You have to remove the image completely, and then add another one in it's place.
So what I am asking is twofold:
1. Can the tinyMCE editor plugins (in this case wpeditimage) be overridden via functions.php or a plugin? Or can I totally override it with my own?
2. Do you agree with me that this is a usability issue in WP, or am I just smoking something?

How to Get All Taxonomies AND All Terms For Each Taxonomy With Post Count Zero
Is there an easy way of obtaining every registered taxonomy and for each registered taxonomy, get all the terms for that taxonomy, and for each term, get the post count, without actually fetching all of the post data?
I would assume it is most definitely possible. I would also assume it requires some massively long database query using `$wpdb`. | You can do this with just `get_terms` \- this allows you to fetch all (or some) of the terms from one (or more) taxonomies.

add a menu item to navigation menu to link to external url
I followed this tutorial to add a menu item to navigation menu to link to external site:
<
I copied the snippet of code to my theme's header.php I created a page with the name having the text that I want to appear in the navigation I added a custom field to the page called redirect and placed the link url into the value field.
And then tested and the link never appears in the menu. | Are you trying to navigate to an external page or redirect? (Also, bear in mind that was posted almost 3 years ago...in websites and technology in general, that's an eternity!)
You could always just add a custom link to the WordPress menu under Appearance->Menus. Just make sure you add support in the functions.php file.
<
And here for adding theme support: <
This is how you would add functional support:
//setup the dynamic navigation
if (function_exists(register_nav_menus)){
register_nav_menus(
array(
"main_nav" => "Main Navigation Menu"
)
);
}
Then go to the admin panel->Appearance->Menus, and add your external link there.
Then in your template, you would call it like so:
<?php wp_nav_menu(array('menu' => 'Main Nav Menu')); ?>

How to create category page
Anybody could help me to make a category page only. Thank you. | You'll want to stick something like this in your theme's `category.php` file:
<?php
// fetch the categories with the parent being the current cat
$sub_cats = get_terms('category', array(
'parent' => get_queried_object_id()
));
if(!is_wp_error($sub_cats) && $sub_cats)
{
foreach($sub_cats as $cat)
{
// Create your grid here, this is just an example
printf(
'<a href="%s">%s</a>',
get_term_link($cat, $cat->taxonomy),
$cat->name
);
}

WP 3.4 - what action/hook is called when theme customisation is saved?
i'm looking for the action/hook called when saving theme customs colors in the new admin interface?
i need to call a custom function to save a set of php generated images.
if anyone have clues... :)
thanks | The settings are saved via ajax, with the action `customize_save`. In the `wp-includes/class-wp-customize-manager.php` class, the callback for this ajax method is the `save` method (see source)
This triggers the `customize_save` action, prior to updating each of the settings.
Each setting is actually an instance of the class `WP_Customize_Setting` and saving the setting triggers the action
customize_save_{$setting_id}
if you wanted to trigger the action when a particular setting is saved (unfortunately there's no filter).
The `save` method calls the `update` method, which behaves different depending on whether the settings is a 'theme_mod' or 'option'. Regardless they are both saved using `update_option` (and so passed through the appropriate filters). The former is done so via `set_theme_mod()`. | stackexchange-wordpress | {

Retrive post by tags PHP code

How can i retrive the movies play by bruce willis in <
For example, i have : < This movie have Bruce Willis Tag....( this is a regolar post in wp)
In Bruce Willis page i want to retrive the movie.... that have Bruce Willis Tag
In conclusion i want to display the movies that actor play in

echo get_post_format();
endwhile; else:
echo 'No movie found';
endif;
wp_reset_query();
?> | I think there are multiple issues here:
1) Because you're using `query_posts()` the post object's query_vars are inherited by your new `query_posts()`. I suspect then, that `'post_type' => 'persoane'` is implicitly part of that query posts call. If you switch to using WP_Query instead of query posts, I suspect that will fix the issue.
2) Have you double checked that `get_query_var('term')` is returning what you expect? I think that only works on taxonomy archive pages. Instead, you'll want do use `get_the_tags()`. | stackexchange-wordpress | {

How do we check if the user is logging in or registering?
I am changing the text on the login page using this filter:
function filter_register_text() {
return "<p class='message register'>Registering for this site will give you access to the admin panel to add new products with images and useful files for others to download and choose open product licenses.</p>";
}
add_filter('login_message', 'filter_register_text');
I just want to show the text if the user **signs up** on the website, not for users who just want to **log in**.
Thanks. | I think your best bet is to check if the `action` parameter is set & equal to `register`:

How do I make specific plugin functionality apply to different sites in a network?
I have a site specific plugin that I've written for the main site in my multisite network. Now I realize that the shortcodes that are in the plugin are also useful on the sub-sites, however the sub-sites don't need all the code for custom post types and taxonomies.
How do I make just the shortcodes work for sub-sites? Is there a conditional I can use? Here's how my plugin is currently set up:
// Plugin Directory
define( 'CLICK_DIR', dirname( __FILE__ ) );
// General
include_once( CLICK_DIR . '/lib/functions/general.php' );
// Post Types
include_once( CLICK_DIR . '/lib/functions/post-types.php' );
// Taxonomies
include_once( CLICK_DIR . '/lib/functions/taxonomies.php' );
// Shortcodes
include_once( CLICK_DIR . '/lib/functions/shortcodes.php' ); | if ( is_main_site() ) {
include_once CLICK_DIR . '/lib/functions/general.php';
include_once CLICK_DIR . '/lib/functions/post-types.php';
include_once CLICK_DIR . '/lib/functions/taxonomies.php';
}

Obtain a list of available translations
In answering this question: Change language by clicking a button. It was necessary to obtain a list of languages for which translations were available (i.e. their po/mo files were present in `wp-content/languages`).
## So how can you obtain that list?
Clearly by 'available' we can only mean that their `po/mo` files are present - and it's not a concern if every plug-in also provides a translation for that language (interesting to see how you might do this though).
The list was originally intended for us in a drop-down, whereby a user could select from a list of (available) languages. So the human readable form of the language _as well_ would be a bonus. But I think this is probably not possible.
View the question linked to above for demonstration of the current method used. | You can get a list of available languages with `get_available_languages( $dir )`. It returns an array with all `.mo` files where the names does not start with `'continents-cities'`, `'ms-'` or `admin-`.
To get a readable name for the file use `format_code_lang( $code )`.
If you scan a directory for language files and get an array like `array( 'de_DE', 'tr_TR' )` this function will build ~~translated~~ names for the languages: `German` and `Turkish`. | stackexchange-wordpress | {

Permalinks not working on new site
I'm setting up a new site on 3.4.1 and the Permalinks will not work.
I have deactivated all plugins and switched to TwentyEleven and they still fail.
I can see through outputting $wp_rewrite that the rules are being flushed when I chnage the structure, and .htaccess is being updated, but no matter what I do, I just get a 404 error.
I also notice that it doesn't matter what structure I use (excluding default), all links are in the format of the /%postname%/ structure.
Any suggestions of what else I can try? Thanks. | As I was always getting a server generated error, a friend of mine pointed out that this meant the `.htaccess` file was not even being read.
He advised checking the `.conf` file for the site, and sure enough, there was a typo in the `<Directory /var/www/...>` entry, meaning that the directory was not being read correctly when a user visited the site. | stackexchange-wordpress | {

Load Javascript from Plugin in One Page Only?
I use the ALO EasyMail Newsletter.
But the plugin is loading lots of Javascript in the head.
I have a mobile site and the scripts are loading in all the pages. I think this affects the mobile performance and want to load it only on the newsletter pages.
How can i do that and load it only in the `/nieuwsbrief` page?
The php starts with:
<script type="text/javascript">
//<![CDATA[
<?php if ( is_user_logged_in() ) { // if logged in ?> | Drop this in your `functions.php` or a custom plugin.
function wpse_57621_alo_tidy()
{
if ( $page_id = get_option( 'alo_em_subsc_page' ) ) {
if ( ! is_page( $page_id ) )
remove_action( 'wp_head', 'alo_em_ajax_js' );
}
}
add_action( 'wp', 'wpse_57621_alo_tidy' );
It's attached to the `wp` hook, which runs just after the request has been handled & queried.
We're saying "if the ALO newsletter page setting exists, but we're not currently on said page, unattach the script output hook". | stackexchange-wordpress | {

Wordpress blog code format
I am new to wordpress and I just created a new blog(free version). Now It seems that code fromat doesn't work. All lines are aligned to the left. Please look at the image below.
!image
Thanks. | You need to wrap your code in either `code` or `pre` tags. `code` is for when inline code in a sentence e.g. `include("hello.php")` whereas `pre` is for preformatted blocks of text e.g.:
function hello_world(){
echo 'hello world';
}
For code highlighting etc, you'll need to look for plugins.
The easiest way of using these tags is using the preformatted style:

Simply Exclude - Category feed exclusion is excluding from category feed instead of just the main feed
I am using Simply Exclude to make sure that certain categories do not show up on the home page and in the sites main feed, < However, excluding the category from the main feed also excludes posts from the category's feed, < How do I get it so that the main feed has these categories excluded but the category's feed remains populated? | It took me a while but I figured it out, I just placed this in mu functions.php file:
function remove_se_filters($query) {
if($query->is_feed && $query->is_category){
global $wp_filter;
foreach($wp_filter['pre_get_posts'][999] as $key=>$filter){
if(strpos($key, 'se_filters') !== false){
unset($wp_filter['pre_get_posts'][999][$key]);
}
}
}
return $query;
}
add_filter('pre_get_posts','remove_se_filters');
I found that I couldn't use the remove filter function because I did not have access to the original class variable that was used to set the filter in the first place so going into the filer's global variable and unsetting the array manually was the next best option. | stackexchange-wordpress | {

Templates have disappeared from drop down lists
