Show 1 post and after a specific date show the next one
I used the following query to have only 1 post published on the homepage from a particular category:
<?php if ( have_posts() ) : ?>
<?php query_posts('posts_per_page=1&orderby=date&order=DESC&cat=6'); ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php wpe_excerpt('wpe_excerptlength_index', 'wpe_excerptmore'); ?>
<?php endwhile; endif; ?>
Each post has two custom fields containing a begin and an end date. What I need is that after the end date the next post (the one with following begin date) will be shown. But I don't know how to do it.
Any hint? | Assuming, as per the above comment, the format of the dates is `YYYY/MM/DD`:
$args = array(
'posts_per_page' => 1,
'cat' => 6,
'meta_key' => 'begin_date', // adjust to actual key
'meta_value' => date( 'Y/m/d' ),

Failed to invoke other hook from the init hook
Related to this question (Use wp init hook to call other hooks?) but not the same.
Sometimes, I found that the hook will failed to run when I place inside the init hook, e.g.
Not Work:
add_action('init','my_init');
function my_init() {
add_filter('locale', ...
}
Work:
add_action('init','my_init');
add_filter('locale', ...
Of course some hooks/filters will just work okay inside the init hook, but **definitely not all of them.**
So it seems to me that **it is a bad practice to chain actions/filters together?** | The `locale` hook happens long before `init`. To see when which hook, variable, constant, function, class or file is available install my plugin T5 WP Load Order.
You get a looong file with a very detailed log. Search for `Hook: locale`, then for `Hook: init`. You will see that you need `plugins_loaded` as parent action if you want to chain hooks.
Is it a good practice? It depends. If you need the second callback only when the first was running successful, then **yes**. If both callbacks should run independently of each other, then **no**.
Chaining should reflect the logic of your program. | stackexchange-wordpress | {

How to use bloginfo( 'template_directory' ) in array
I want to pass `bloginfo( 'template_directory' )` in an array
I tried this but not working. How to write it correctly?

'default_image' => bloginfo( "template_directory" ) .'/img/dflt.png',
'image_scan' => true,
'link_to_post' => false ) );
?>
`get_the_image` is a function from Justin Tadlock plugin | `bloginfo()` is using `echo`, you need a function that returns its value: `get_bloginfo()`.

Does WordPress cache get_user_meta() results?
If I call get_user_meta() to retrieve a value, does WordPress cache the value? If I call get_user_meta() to retrieve the same value, does WordPress have to query the database again or is it stored in PHP memory? | Yes, it does. That function is a wrapper for `get_metadata()`. Inside of that you can find:

Why execute the_post()?
When I'm getting custom post types with WP_Query->query(), it isn't really necessary to execute the the_post() function, because you can iterate over the query result array. Is it considered good behaviour to do this, or is it truly just a convience method? | It is necessary to execute that function if you want to use the template functions such as `the_title()` & `the_permalink()`. You should not use it if you aren't using those kind of functions but for the themes it's generally recommended to use these functions since they automatically ensure that all wordpress filters are being applied. This functions modifies the global variables but still it's safe to use as long as you also reset the postdata after finishing the query.

Using wp_enqueue_script with social media buttons?
I want to embed a social sharing button in the theme. Following is the standard code to embed the twitter button.

However, WordPress recommends to use the `wp_enqueue_script` to include any kind of javascript code. So I am wondering how can I include the above script code properly in a WordPress theme? Thanks. | Put everything between `<script>` & `</script>` in a separate file. Then use `wp_enqueue_script` with the correct path of the file & dependencies to false.

Separate Media Library for each user
I'm creating a theme for a client and one of their requests is to allow users to upload images for their own use, but there may be an option to share the images.
Here are some of the caveats:
* Each user has the ability to upload their own images to their own Media Library.
* These images must be capable of being 'tagged' exactly similar to how we 'tag' 'posts' now.
* The Admin can manage these images also.
Firstly is this possible and is it possible to create a 'tag' taxonomy for images?
Thanks for your help. | ## Built in features
The Media Library has major updates with the upcoming version. You can see the changes in the slides by Daryl Koopersmith here. You can read the announcement and discussion on "Make".
> Your request for "tags/categories" is already built into 3.5.
### Note
The difference between themes and plugins is pretty easy: Display vs. Functionality. So I'd suggest to not build such functionality into a theme, but keep it separated as plugin. Your benefit from doing this: You/Your client wouldn't loose this functionality on update or theme change. It simply makes your life a lot easier. Imagine, that you got another client requesting this. Then you'd simply upload your already existing plugin instead of ripping this out of your theme and moving it into the next theme. | stackexchange-wordpress | {

WP e-commerce: getting products by SKU
I'm working on a site that uses the WP e-commerce plugin (Gold version) and I need to display a list of products that match a list of SKUs. Users fill in a form, and a list of product SKUs is generated depending on their answers. I need to create a page that fetches these products and displays them, preferably in the default grid view/list view style.
Any ideas how to do this? Looking through the documentation, I was expecting a "get_products()" function that could take the SKU as an argument, but there doesn't seem to be anything like that. How could I go about doing this?
Thanks a lot,
Will | WP E-commerce uses WordPress post objects to store products, so you don't need any special functions or callbacks. `query_posts` will support everything you need, you can learn about the details of how everything is set up by reading about their database schema.

Wordpress apply_filters() Arguments Missing
I'm customizing a Woocommerce Wordpress site.

function get_price() {
return apply_filters('woocommerce_get_price', $this->price, $this);
}
In my functions.php I want to add a filter as follows:
add_filter('woocommerce_get_price', 'custom_price');
function custom_price($price, $product) {
...
}
When I call this I get the following PHP warning:
Warning: Missing argument 2 for custom_price()
Why is the second argument missing? Is `$this` not sent to the filter call? | It's missing the second argument because you didn't tell WordPress you wanted it with your `add_filter` call. By default, actions and filters only get one argument. Try this:

Allow all attributes in $allowedposttags tags

'src' => array(),
'height' => array(),
'width' => array()
);
How can I allow all attributes in this example, not just src, height, and width? | I'm pretty sure you have to explicitly name all allowed attributes - just use:

Redirect from the dashboard to edit.php if wp_is_mobile() is true

function redirect_if_mobile() {
$screen = get_current_screen();

$url = admin_url( 'edit.php' );
wp_redirect( $url );
}
}
}
add_action( 'admin_menu', 'redirect_if_mobile');
The problem is that `get_current_screen()` isn't defined in either `admin_init` or `admin_menu` (if you hook onto `admin_head` instead it's too late and headers have already been sent).
Ideas? | The action you're looking for is auth_redirect, which is before the headers but still recognizes $pagenow to tell which page you're on:

function the_mobile_boot() {
global $pagenow;
if ( $pagenow == 'index.php' && wp_is_mobile() ) {

Offset Loop by 1 , Limit next loop to 1 (Most Recent) Post
I have a loop that I would like to Offset by 1 so the most recent post is not displayed, and another loop where I only want 1 item which would be the most recent post.
These are the loops I tried: for both:
Offset Loop: `<?php query_posts('offset=1'); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>`
and Most Recent Post Loop: `<?php query_posts('posts_per_page=1'); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>`
The page doesnt load for me when I tried this, any ideas? | Neither of those are complete loops. That is, in both you have the start of an `if` but not the end of it, and the start of a `while` loop, but no the end of it. Also, you shouldn't be using `query_posts` either, as it over writes the main query and is rarely the right function for pulling posts. `get_posts` would be better.
I would do this, using one as an example:
<?php $r = get_posts('offset=1');
if ( !empty($r) ) :
foreach ( $r as $post ) :
setup_postdata($post);
// stuff
endforeach;
endif; ?>
That should solve your problem with the page not loading.
What you are doing can be done with a single loop though, since get_posts without the offset will pull everything. You just need to take the first element as the recent post and loop through the rest. | stackexchange-wordpress | {

Blog post not showing title

* Blog posts index hierarchy: `home.php`

How and where is wordpress adding mySQL content to database?
I am currently following this steps to change server and domain for my website. I have been exporting and importing mySQL from one data base to the other. I am about to delete the mySQL content of the database to replace it. I am scared that it will mess up my website.
How does Wordpress create mySQL content on the DataBase and how can I make it re-write the content. In other words: why do i need to export and import the data base from the previous website and not just allow the wordpress files on the FTP to generate the new mySQL content?
many thanks | The files on your server are the WordPress app, themes, and plugins. All page, post, widget, user, and plugin data only exists in the database.
When you create a page or post, add a user, leave a comment, etc., WordPress is writing that data to the database and nowhere else. When a visitor loads your website, the data is loaded from the database and inserted into your template for each page view.
Without the data in the database, the content for your site is irretrievably lost. This is why regular database backups are important, and care should be taken in moving the data. | stackexchange-wordpress | {

How to display text of a page in home or custom page?

-Navigation-
_-About Us - -Some part of About us page content_ -
-Latest News- -The loop for latest news-
How can I do the 'about us' part? Thanks | You would use `get_pages` function or create custom query using `WP_Query` class. The codex pages have detailed descriptions of parameters for both functions.
If this is a theme that you want to release for broader public you would probably want to create a theme options page where user sets the page that he wants to display.

How to switch between the Primary Menus programmatically?

So how can i switch between these Primary Menus at the runtime (Programmatically from the Frontend .. WITH A BUTTON CLICK or something) ? | you can do it on the clientside, if you output both menus and change the visibility on the click of the button via javascript.
if you want to do this on the serverside, you could make another template or a `if` to output the menu you want to show to the user.

Import Images from one self-hosted WordPress install to another
I am redeveloping a client's site and, for a number of reasons, in the process changing hosts. I'm developing it on the new host and to get the site orgainised I have attempted to import all the pages from the old site using the WordPress export/import plugins.

old site: < | Although Chip's method may work for some it did not for me. I did get it working however this way:

2. Download the wp-content/uploads folder via ftp from your old site and upload it to your new site, replacing what's there.
3. Go into phpmyadmin on the old site and use an SQL query to select all posts that have post type = "attachment" in the wp_posts table. Export the results of this query and save on your PC.
4. Export the wp_terms table from your old site.
5. Import both the mySQL exports from your old site into your new site via phpmyadmin.
6. Use the "search and replace" plugin to replace all occurrences of your old domain in your database with your new domain.

Contact Form 7 not sending emails- no confirmation, no error
Live site.
I've noticed that Contact Form 7 recently stopped working, despite my not having touched any of the settings. What's odd is that I receive neither a confirmation nor an error message; I click "send" and nothing happens. This problem persists across FF, Safari, and Chrome.
I read in other, older threads that it could be something to do with SMTP settings, but as the threads were 2 years old, most of the work-around plugins they suggested are no longer an option.

Blog page won't show Blog template
I set my "Blog" page to a Blog template I created in Pages (in the dashboard). Also, in Settings > Reading, I set my Home page (home template) as my Front page and my Blog page as my Posts page. However, when I navigate to my Blog page, it shows the home template. Yet, the body class of the Blog page is `blog logged-in`. I am confused. How can I make my Blog page show my Blog template?
I pasted my Blog template here for reference: < | Based on your comment:
> 1) **blog.php** What is the file name of your blog custom page template? 2) **home.php** What is the file name of your front page custom page template?
The answer is simple:
The `home.php` file name is a **reserved** file name in the WordPress template hierarchy, and is used by the template hierarchy to render the **blog posts index**.
So, WordPress is doing exactly what you've told it to do. :)
Simple solution:
1. Rename `home.php` (your **Front Page** template) as **`front-page.php`**
2. Rename `blog.php` (your **blog posts index** template) as **`home.php`**
**Note** : you'll have no need to select either template explicitly, since WordPress will use both automatically. (You need only configure **`Settings -> Reading`** properly, which you've already done.) So, you can also:
* Remove the **`Template:`** PHP header tag from both files. | stackexchange-wordpress | {

Add Wordpress MU Network Admin via Database
I am working on getting a copy of a WordPress MU network up and running on my local machine for development purposes (using WordPress 3.2.1 at the moment). I need access to the network administration options.
In the usermeta table, I changed my `user-level` to `10` and `capabilities` to `a:1:{s:13:"administrator";b:1;}`
In the sitemeta table, I added myself to the serialized array of users in the `site_admins` option.
While this did get me access to the generic wp-admin page, I still do not have access to any of the network admin options (such as automatic upgrade for WP, plugins, or themes, etc). | So, it turns out that those three changes were all that were needed. It also turns out that if any of the serialized arrays are modified incorrectly (which is easy to do when modifying them by hand), the system will just assume you are not a network administrator.
Correcting the serialized array for the `site_admins` option fixed the problem. | stackexchange-wordpress | {

How do I serve fully cached full HTML on cloudfront
I am using cloud front but want it to serve not just images and CSS but full static HTML pages that are cached locally. I am using wp super cache ... I assume it is caching the full HTML for posts and pages.
But I am thinking it would be better to have as much of the site in Cloudfront.
I am currently using origin pull, but again it looks like HTML pages as just cached locally.
My site doesn't change much it is mostly interviews updated every couple of weeks. | Yes, you can serve HTML through CloudFront as long as you don't mind every user getting the same content until the cache expires. It completely depends how your caches are being stored.
I can't imagine a CDN that would not support this. They might not advertise it since many web sites are dynamic and can't be cached, but if your site is basically static, then any CDN should work.

How can I remove the image attachment ALT field?
I've been using the technique described in this post to remove the caption and description fields in the uploads modal window, thus eliminating unused clutter for users.

how to display custom fields of post on a web page

**$single** _(boolean) (optional)_ If set to true then the function will return a single result, as a string. If false, or not set, then the function returns an array of the custom fields. This may not be intuitive in the context of serialized arrays. If you fetch a serialized array with this method you want $single to be true to actually get an unserialized array back. If you pass in false, or leave it out, you will have an array of one, and the value at index 0 will be the serialized string. Default: **false** | stackexchange-wordpress | {

Create a live demo gallery for themes
I want to create a live demo site like < that show themes so when I click on the theme screenshot it takes me to the live theme preview.
I tried two plugins themebrowser and wordpress-theme-showcase they are showing the themes in a list and I can click the theme to view, but when I'm trying to go to any page inside the preview theme it takes me to the original theme that already installed, so also I want to be able to browse the demo theme pages and posts like if it is activated.
Thanks
Edit: From the source code of wordpress-theme-showcase plugin the Theme Preview URI: php?preview_theme=WordPress%20Default and that's ok for he home page of the new theme, but if I want to go to some page it redirects me to the home page of the installed theme. So I tried to add &p=1 (post url) to the end of the Theme Preview URI above and it works. The question now is how I can append this url to all the links in the preview page | # Solution
I used the wordpress-theme-showcaseplugin to show a list of themes in the home page, and to can easily browse the theme that is currently preview I changed the way wordpress handle the permalinks. In the wp-includes/link-template.php file in get_permalink function added this code
if(isset($_GET['preview_theme'])){
$permalink = home_url('?preview_theme='.$_GET['preview_theme'] .'&p=' . $post->ID);
}else{
$permalink = home_url('?p=' . $post->ID);
}
and in _get_page_link function added this code
if(isset($_GET['preview_theme'])){
$link = home_url("?preview_theme=".$_GET['preview_theme'] ."&page_id=$id");
}else{
$link = home_url("?page_id=$id");

Insert into post button missing on custom post type
I have just purchased a theme called **HQ Photography** from themeforest which has a custom post type called `gallery`.
I can add images from my hard drive no problem - but if I click the media tab and select an image the 'Insert into post button' is missing

function force_send_to_post($vars) {
$vars['send'] = true; // 'send' as in "Send to Editor"
return($vars);

This brings the button back but the button then does nothing.

How to call a plugin function from index.php
I have created a function in my plugin `myplugin` with the name `foo`, how to call it from the frontend?
e.g. index.php? | The same way you would any other:
foo();
Active plugins are loaded before the theme files
You may want to check that your plugin is activated and the function is available so things dont go pear-shaped if you forget to activate it, like:
if(function_exists('foo')){
foo();
} else {
echo "oh dear you haven't activated/installed 'myplugin', go do that before the 'foo' feature is available";
}
Also keep in mind `foo` is a very generic function name, perhaps the "omgfoo" plugin also has a `foo` function. So prefix/namespace your function to something unique

Is it bad to store many files in a single folder?
I upload thousands of images and it stored in a single folder. Is it bad if too many images are in a single folder? would that slow down the loading of the image even though you're viewing an attachment image which has a path defined? | No the depth of your directory structure has almost no impact to load time.
Maybe if your structure is very depth and the URLs for the images are very long you can hit the maximum length or your markup blows up. But a flat hierarchy should not be a problem as long as you keep the file names short enough.
Then again, if your store everything in one directory, there may be name collisions. But WordPress checks for that during the upload with `wp_unique_filename()`, so you should not worry about that too. | stackexchange-wordpress | {

After installing/activating AWPCP (Another Wordpress Classified Plugin), when I type wp-admin/ I get a blank page but with /wp-login.php the login appears.

WP query by custom post type slug/name
I am running a simple wp query to retrieve just one post.
But the post is a custom post-type post, not a normal post
$ajaxBike = $_GET['varbike'];
$bikeProfile = new WP_Query(array(
'name' => $ajaxBike,
'meta_query' => array(
array(
'key' => 'app_visibility',
'value' => 1,
'compare' => '='
)
)
));
or...
$ajaxBike = $_GET['varbike'];
$bikeProfile = new WP_Query('name='.$ajaxBike);
But I think the **name** parameter only works for posts. But I'm struggling to find anything to work with a custom post type slug.
Can you anyone help work out how to query a custom post type using the slug?
Thanks in advance! | 'post_type' => 'custom post type slug'
By default 'post_type' is set as 'post', you will need to specify your custom post type in any query you make.

wordpress get gallery images title
I am retrieving some images post with:
$img = wp_get_attachment_image_src( $attachment_id, 'full' );
How can I retrieve the image title?
Thanks. | In WordPress attachments are stored as posts so you can use most of the post specific WordPress calls and functions to read/write data associated with the attachment. This applies to post meta data for an attachment as well.
So in this case, since you have the post ID ( same as $attachment_id ) you can simply use the `get_the_title()` function:
$sImageTitle = get_the_title( $attachment_id );
This returns a string of the post's title for the given post ID.

How to display some settings for super admin user only using Settings API
I'm developing a plugin with an options page using the Settings API.
I'd like to have one options array stored for my plugin, but on the settings page, I'd only like some of the settings to be visible to admin users, but the full list of settings to be available to the super admin.
Is this possible? | Test the current user’s role with `current_user_can( 'administrator' )`:

Wordpress $wpdb no result

Replace function in a child theme
Is there a way to replace a function by another function in a child theme? In other words, in a theme there is a function named "theme_function" and this function is called by several files inside the theme.
I would like to find, if exist, an action that replace all occurrences of "theme_function" with another function "child_function" inside the child theme. Please note that "theme_function" that I want to replace do not have the following block:
if ( !function_exists('theme_function') ) :
because if it that case is easy to replace the theme_function with another function having the same name in functions.php | If the parent-Theme function in question isn't either pluggable (i.e. wrapped in a `if( ! function_exists( $function ) )` conditional) or filterable (i.e. returns its output wrapped in a `apply_filters( $filtername, $output )`), then there's no easy way to override the function.
You'll have to do one of the following:
1. Replace all template files that contain instances of the function call, and replace those calls with your own child-Theme function, in all such templates
2. Modify the parent Theme, to delete (or make pluggable) the function in question | stackexchange-wordpress | {

WordPress Admin Interface not styled properly
The laptop I was working on recently crashed. But, I managed to get everything on it backed up, including my recent WordPress project off of my local server (I use MAMP).

Is there a better way to pull in custom content without querying posts?
I have a custom page template that pulls in media files via advanced custom fields, as well as query posts. Now, the client wants there to be three sections by default... each one populating with the appropriate images based on another advanced custom field for an image category (which I created).
Normally, I would just query_posts three times. Undoubtedly, this is a hack. Normally, it doesn't cause speed issues, however this site has roughly 50k images, and I'm afraid it will cause the load times to significantly decrease.
Is there a better way to do this way to do this? Maybe pull in all images and then sort them based on the category? | It's not a hack, this is what databases are designed for- querying large quantities of data. If you're concerned about load, you should employ caching on data that doesn't change frequently.
That said, you should not be using `query_posts` to create additional queries. Really, you shouldn't be using query_posts at all. Create additional queries via `WP_Query`. | stackexchange-wordpress | {

Using global $post v/s $GLOBALS['post']
It's probably more of a PHP question, but I would like to know if there are any differences in using
global $post;
echo $post->ID;
when compared to
echo $GLOBALS['post']->ID;
to access the ID of a post in WordPress.
This answer on SO suggests that the first method is quicker to process, while the second method is quicker to write.
I also noticed that the first method is often mentioned in the Codex while the second method is mentioned on `the_content` filter page.
Is this only a matter of preference? Or does it come to performance and security too?
Thanks | There is no difference when you are using just `echo`. What works different is `unset()`:
function test_unset_1()
{
global $post;
unset( $post );
}
function test_unset_2()
{
unset( $GLOBALS['post'] );
}
test_unset_1();
echo $GLOBALS['post']->ID; // will work
test_unset_2();
echo $GLOBALS['post']->ID; // will fail
The reason is that `unset()` destroys just the local reference in the first case and the real global object in the second.
For readability use always `$GLOBALS['post']`. It is easier to see where the variable is coming from. | stackexchange-wordpress | {

Using get_terms for custom taxonomy in functions.php
I`m trying to retrieve the names of taxonomy items and include them into a theme admin panel.
function retrieve_my_terms() {
global $terms;
$terms = get_terms('taxonomy');
foreach ($terms as $term) {
$option = $term->name;
return $option;
}
}
The function is added after the functions which created the custom post type and taxonomy.
From what I've found out, it seems that the `init` action occurs after the theme's functions.php file has been included, so if I'm looking for terms directly in the functions file, I`m doing so before they've actually been registered.
In other words, init action doesn't fire until after the theme functions file is included, therefore any term retrieval must occur after init.
My problem is that I don`t know how to retrieve the terms after the init.
Any answer will be much appreciated!
Thank you! Madalin | You can add the action on the init itself, just increase the priority of the `add_action` call. The higher the priority the later the function is called.
`add_action('init', 'retrieve_my_terms', 9999);`
But my suggestion is that you should do these kind of things as late as possible, preferably just before the first time they are used. There's an action `'wp_loaded'` which gets called after full wordpress has been loaded & ready to start working on the output. That action might work for you. | stackexchange-wordpress | {
