Searchresult sidebar change
So, where is the searchresult page sidebar located?
For example, in the searchresult page, there is "A" sidebar.
However, I want to change it to "B" sidebar.
I looked at `search.php` but could not understand where the sidebar was coming from. | Your search.php may contain the following code
<?php get_sidebar(); ?>
If a name ($name) is specified as an argument then a specialized sidebar sidebar-{name}.php will be included. If sidebar-{name}.php does not exist, then it will fallback to loading sidebar.php.
If the theme contains no sidebar.php file then the sidebar from the default theme will be included | stackexchange-wordpress | {

Return the most recently created custom taxonomy
I'm using a plugin (IssueM) which gives the "articles" post-type a custom taxonomy called "Issues".
I need to find and store in a variable the most recently created one of this taxonomy. So, for example, within `Issues` I have `issue-one` through to `issue-five` \- I need to return `issue-five` as it was created most recently.
How can I access this custom taxonomy by date? | Use get_terms to select that custom taxonomy, ordering by id DESC and returning only one record:
$latest_term = get_terms( 'issuem_issues', array( 'orderby' => 'id', 'order' => 'DESC', 'number' => 1, 'hide_empty' => false );
This presumes that your WP DB is set up normally, so the highest ID number on the custom taxonomy terms will be the most recently added term.
Also, make sure the _slug_ for the custom taxonomy is Issues, not issues. The slug query is case-sensitive. | stackexchange-wordpress | {

Updating From Mobile App - Exposing Site to Hacking
I have made a simple Mobile App to update a wordpress site.
It starts with a login (to the app) and then with forms, sends data via POST method to a PHP file that then uses `wp_insert_post`, `wp_insert_attachment`, `add_post_meta`, etc to create the new post.
My concern is that this PHP page is not secure. If anybody got hold of the filename, they could insert anything to my site. My PHP file uses `include ("wp-load.php");` and then does its work, but I feel there is something I am missing as far as user verification that I can't figure out how to do via searching online. Any pointers to where I can learn about this would be appreciated.
I have tried to deconstruct the Wordpress Mobile App, but it is a little too complex for me. | The safest way to manage content from outside of the WordPress dashboard, and make use of the WordPress roles and capabilities model, is via XML-RPC.
The basic methods built in to WordPress XML-RPC allow you to add, edit and delete posts and media, and restrict the ability to do so based on WordPress user permissions. The problem is that it's a little complicated to use if you're new to programming, and the built-in XML-RPC methods are limited in terms of functionality.
For example, creating a new post with four images, and making one of those images the featured image, and adding different taxonomy terms to the post (categories, tags, etc.) based on some arbitrary criteria can require either making several XML-RPC calls in a certain order, or the need to create a custom XML-RPC method.
Here's a fairly basic primer on WordPress XML-RPC using the Incutio XML-RPC library, which is what WordPress core uses to handle XML-RPC requests: < | stackexchange-wordpress | {

Website visible only to Registered users (non wp-admin)
I have created a page with a custom login using `wp_login_form()` function but how can I redirect all visitors to that page in similar way described in that topic?
My code looks like:
function redirect_to_login_if_guest() {
global $post;
if ( ! is_admin() && ! is_user_logged_in() && $post->ID !== 4667 ) {
wp_redirect( get_permalink(4667) );
exit;
}
}
add_action( 'wp_loaded', 'redirect_to_login_if_guest' );
but somehow is going into infinite loop instead of a login page. It looks like `wp_loaded` can't be used in my case.
Similar code moved to the `header.php'
global $post;
if ( ! is_admin() && ! is_user_logged_in() && $post->ID != 4667 ) {
wp_redirect( get_permalink(4667) );
exit;
}
works flawless so still it points on triggering action on `wp_loaded`. Any thoughts? | In short, the `$post` global isn't setup at the `wp_loaded` state. See:
* When and Where is `global $post` Set and Available?

Multisite 404 errors and non-www redirecting to home page
My primary website on a multisite network was created with the `www` prefix (like `www.example.com`).
If I try to access pages without the `www` prefix (like `example.com/page-name/` instead of `www.example.com/page-name/`, I am redirected to the homepage (`www.example.com`). I would like to change this so I am redirected simply redirected to the same page URL, only with the `www` prefix.
Additionally, the 404 error page doesn't work on the primary site. No matter which non-existant URL I try (such as `www.example.com/thisdoesnotexist`), I am always redirected to the primary site home page (`www.example.com`), rather then seeing the theme's 404 page.
Here is a link to my site where you can test the issue. | There is currently a bug in the functionality that handles the `NOBLOGREDIRECT` constant, which causes 404 errors on the main site to be redirected to the value of the constant. Apparently this is the expected behaviour for sub-directory networks (`example.com/subsite`), but should not take place on subdomain networks (`subsite.example.com`).
There is a WordPress Trac ticket (#21573) concerning this bug, but there is no indication on when it might be resolved. Until then, you can resolve this error yourself by removing the `maybe_redirect_404` function:
remove_action( 'template_redirect', 'maybe_redirect_404' );

How to filter posts in admin by before date or by post status 'future'?

Content alignment in Twenty Fourteen Theme

How to implement theme shortcodes in text outside of pages?
I am working on a project where the admin can enter text that will be presented in a custom template. Once the text is written it is saved to the dB then pulled out and presented when needed.
The problem is that the theme we are using uses shortcodes for some of the design elements. So when the shortcodes are used in this text, and the text is 'echoed' back, the shortcodes are ignored.
Is there someway to pre-process the text so WP will insert the shortcodes?
These shortcodes are not mine, they are from the theme, so the text needs to recognize and activate these shortcodes. | You can run the text through `do_shortcode`:
echo do_shortcode( $your_text_with_shortcodes );
or you can apply `the_content` filters to the text, which does the same thing as above along with some additional formatting goodies, like auto paragraphs and texturize:

Disabling outbound connectivity on web servers
Is it a good idea to harden your web server by disabling outbound connectivity on them?
I am using RHEL 7 for a WordPress Multisite installation.
After disabling outbound connectivity, the dashboard has become extremely slow, and the plugins page does not list the latest available ones.
Could I still live with this? What are the biggest disadvantages? | WordPress uses an HTTP class to make outbound requests. These requests are mainly for plugin, themes and core updates; pull news/rss content; and make third party API requests.
There may be many different reasons for disabling outbound requests, security is the primary one. A WP instance with disabled outbound requests is more secure. Many institutions have intranets or secure networks that do not allow external requests. If the outbound requests are not disabled within WP, then WP admin console will not function properly due to timeouts.
The main disadvantage of blocking outboud requests is blocking third party APIs or any external requests. There are many plugins that will not function if you do so.
If you want to disable WP from making any outbound requests add these settings in wp-config.php: ` define('WP_HTTP_BLOCK_EXTERNAL', true); // block external requests define('DISABLE_WP_CRON', 'true'); // block WP cron ` | stackexchange-wordpress | {

Change CSS when user is logged in
So I have the following code:

<?php if ( is_user_logged_in() ) { ?>
<div class="otherseller"> <a class="allotherseller" href="#">Else</a> </div>

Then, for the "sellertitle," I have the following CSS:
<--logged in-->
.sellertitle {
float: left;
width: 49%;
}

However when the user is logged out, I want the "sellertitle" CSS to be "float:none"
<--logged out-->
.sellertitle {
float: none;
width: 49%;
}
What would be the best way to achieve this? | Here is another CSS-only approach, without any inline-PHP and needless CSS-spam in the head. If your theme is correctly using body_class() and a user is logged in, Wordpress adds a class "logged-in" to the body-element, so we can use this in our stylesheet:
<--logged out-->
.sellertitle {
float: none;
width: 49%;
}
.otherseller {
display: none;
}
<--logged in-->
.logged-in .sellertitle {
float: left;

Adding a class to shortcode API

Since two pages are using one identical shortocode, I am thinking of adding a class to the first page so that I can customize the first page shortcode only.
So here is my question.
1. Do you think that adding a class to the shortcode in the first page would allow me to customize it?
2. If so, what is the proper way of adding a class to the above code?
3. If not, what would be an option to add customization to a shortcode for only specific page?
Thank | If it really is just for one page you could use a conditional on `the_ID();` from within your shortcode class (it is a custom shortcode right?)
$class = the_ID() == 213 ? "some-other-class" : "";
$myhtml = sprintf("<div class='some-class %1$s'>%2$s</div>",
$class,
$content);

Which is the recommended method to transfer a wordpress site to wordpress Multisite?
I want to create a wordpress site on my local server and then trasfer it into another server that runs a wordpress multisite installation.
Which way is safer to follow:
a) install a wordpress single installation in my local server and after development export it and import it to the wordpress MU which already has a blank site and the theme and plugins installed
b) install a wordpress MU installation in my local server and after development export the specific site and import it to wordpress MU which already has a blank site and the theme and plugins installed
Is any of the above recommended or both are the same?
P.S: the requirements say that WP version has to be 3.6.1 | Using the WordPress XML export doesn't work in every case. Especially if you have to deal with plugins.
I had the best results if I first installed the theme and all plugins in the network, created a new site, activated theme and plugins (in case they create data base tables) and then import the WordPress XML.
For NextGenGallery it didn't work, though. I had to copy all images and the data base tables manually. The path for each image needs to be mended with search and replace, since in the network installation you'll use blogs.dir/<number>/ for uploads. | stackexchange-wordpress | {

I have a multisite setup where I would like site Administrators to be able to add New Users with the Skip Notification Email option.
By default, Wordpress only allows Super Administrators this privilege in a multisite setup. I have used the code below to fix this problem except it logs the Administrator out after each New User is added. I have tried removing the redirect line but the administrators are still being logged out.
function your_disable_activation( $user, $user_email, $key, $meta = '' ) {
// Activate the user
$user_id = wpmu_activate_signup( $key );
wp_set_auth_cookie( $user_id, true, is_ssl() );
wp_redirect( /*redirect to */ site_url() );
exit;
}
add_filter( 'wpmu_signup_user_notification', 'your_disable_activation', 10, 4 );
How can I run this code (or similar code) without the Administrator being logged out each time?
Thanks! | Update: I've got it working now! It still shows a text box that says the User email must be confirmed, but it DOES create the user regardless of that information. Here is the code I have used:
function your_disable_activation( $user, $user_email, $key, $meta = '' ) {
// Activate the user
$user_id = wpmu_activate_signup( $key );
wp_redirect( /*redirect to */ site_url() );
return false;

Add a wp editor to custom plugin and save data
I'm creating a custom plugin. One of the fields in the plugin let's the user add data.
If I add a `textarea` the user has no control over the text. So I would like to add a editor.
I know WordPress offers the `wp_editor();` function.
After some Google-ing I found that it is very easy to implement the editor.:
$content = '';
$editor_id = 'mycustomeditor';
wp_editor( $content, $editor_id );
This shows a nice editor. The problem is that the content isn't getting saved.
The editor is a part of a form so I thought I add the save function to the form save function like this:
`if( isset( $_POST[ 'mycustomeditor' ] ) ) {update_post_meta( $post_id, 'mycustomeditor', array_map('sanitize_text_field', $_POST[ 'mycustomeditor' ]) );} ` However WordPress thinks different about this. It does create the `meta_key` in the database but no value.
I hope anyone can see what I'm doing wrong! | Solved it!
Hope somebody else can use it or it answers their problem. If there is a better way please share and tell why.
$editor_id = 'custom_editor_box';
$uploaded_csv = get_post_meta( $post->ID, 'custom_editor_box', true);
wp_editor( $uploaded_csv, $editor_id );
To save the data:
function save_wp_editor_fields(){
global $post;
update_post_meta($post->ID, 'custom_editor_box', $_POST['custom_editor_box']);
}
add_action( 'save_post', 'save_wp_editor_fields' );

Display posts from catagories
I am using an option framework. This saves catagory ids.To get ids I have done
$cat = $atts['post_catagory'];
var_dump($cat);
The var dump result is
`array (size=2) 0 => string '1' (length=1) 1 => string '15' (length=2)`

$args = array( 'orderby'=> ASC,'cat'=>$cat);
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post );
the_title( '<h2 class="entry-title"><a href="' . get_permalink() . '"
title="'.the_title_attribute( 'echo=0' ) . '" rel="bookmark">', '</a></h2>' );
endforeach;
But I got error. Also can do the same query using wp_query? Thanks | `cat` needs to be an `int` or `string`, and you are passing an `array`. Either use `category__in` instead, which accepts an array, or convert `$cat` to a string of values with `implode(',', $cat)` | stackexchange-wordpress | {

Child Theme Fatal Error

Button linking to an unique link
Here is the PHP that I have which i am trying to change:
global $current_user, $post, $product;
?>
<?php if ( $post->post_author == get_current_user_id() ) { ?>
<div class="wpproductedit">
<p class="wpproducteditbutton"><a href="

Here, the button only takes the user (author of the product) to product page which then they have to find the product they want to edit.
So any product edit page will have the following URL:

In summary, I am trying to edit the "Edit" link so that it will be like the following and picks up the product name automatically.
| If I understand your question correctly, I think what you are looking for is `edit_post_link();`
To use it just insert `<?php edit_post_link(); ?>` into your theme. This will output a edit link leading to the current page/posts editor.
**Update after rewrite of question:**
You can replace your link with the following to include the posts slug in the url.
`<a href=" echo $post->post_name; ?>/edit">`

Avoiding "Usage of a direct database call is discouraged"
WordPress-Coding-Standards reports that _"Usage of a direct database call is discouraged."_
It's complaining about my usage of `$wpdb->insert()` in a plugin. Is this not recommended? What is the correct way to insert data into a plugin's database table?
Or can I just ignore this error? In which case, is there some system to mark it as reviewed and not to be flagged again? | Using `$wpdb->insert` and or related methods to modify data within any of the default WordPress tables, be it **posts, postmeta, user, usermeta** etc is discouraged because there are functions which already exist for the purpose of modififying data within those tables.
For example,
* `wp_insert_post`
* `wp_update_post`
* `wp_delete_post`
## Database Queries
> Avoid touching the database directly. If there is a defined function that can get the data you need, use it. Database abstraction (using functions instead of queries) helps keep your code forward-compatible and, in cases where results are cached in memory, it can be many times faster.

However **it is acceptable** to use the `wpdb` class on custom tables for which no function wrappers exist for the purpose in which you need.

How to get attachment id as soon as it is uploaded through media uploader in jquery?
Using jquery, I am trying to get image attachment id of all images requested to upload through media uploader on post edit page or upload.php. Here is what I tried but this works after all images are uploaded:

wp.Uploader.queue.on('reset', function() {
console.log('images uploaded!');

How can achieve the same? Thanks | You are close, you just need to hook into the `add` event instead of the `reset` event. (In case you did not know, these are standard events provided by Backbone collections. So familiarizing yourself with that will be helpful when developing things around stuff where WordPress employs Backbone.js.)
So basically you'd modify your code like this:

How to activate or install the Gallery Widget?

Create various image sizes ad hoc

Best Regards, and thanks in advance | You could, but I wouldn't recommend doing it on the fly as it would take up unnecessary page resources each time the user loads the page. A better way to do it would put in the add_image_size hook you mentioned into the functions file, then install a plugin to regenerate thumbnails. < I've used this one in the past and worked very well.

So how could I disable this copying and renaming? | The renaming to test1.jpg is not due to any cropping / resizing functions WordPress. This is because you already had a file named test.jpg uploaded, and WordPress does not replace files if one exists in the folder that has the same name.

Displaying Widgets
During theme development, I understand how to create basic widgets within the `functions.php` file.
However, when it comes to displaying the widget within a theme, is there a preferred way to display them - primary, what are the benefits of using the `the_widget()` function versus the `dynamic_sidebar()` function? | `the_widget()` is used to display a specific widget outside of a sidebar. To be honest, this function serves no valuable purpose as you need to hard code the widget `$instance` parameters, this means that you will need to manually change the code every time you need to change something. So much for dynamica. It would just be easier to simply code a custom function and then calling it in your template where needed. It will be faster and much easier to use
Stick with widgets inside sidebars as they are dynamic and can be changed without touching theme or plugin code. I would rather code twenty sidebars and add them in strategic places than using one hardcoded instance of `the_widget()` | stackexchange-wordpress | {

I know AAM or any alike plugin serve as an interface and there are ways to look through the files/codes to make this happen. I found in wp-includes/capabilities.php is where this gets managed but I am assuming not for each specif site as I can't find anything about other sites in there. Does each site have its own capabilities.php somewhere? | I believe you'd need to modify user roles on each site individually (if I'm understanding your question correctly).
There's a great plugin I use frequently called WPFront User Role Editor that allows you to check/uncheck user capabilities like you mentioned. The free version should be fine for what you're trying to do. I personally use the paid version just because I like to have the extra options when I need them, but 90% of the time the free one works fine.

Should I use Multi Site to achieve different designs for different sections?
I'm about to start a website where I'll need to have a different "feel" in design, and in information displayed, for each section.
So, for instance, when you go to the "chocolate" section the design has to be brownish overall (pages, posts and archives), and the sidebar should show chocolate-related material. When you go to the "candy" section, it should be a "pink" design with a sidebar displaying info about candy, and so forth...
How can I achieve this? Do I need a Multi-Site installation? Is there a downside to using a Multi-Site install for this purpose? | Multisite isn't really the best option here.
If you need different layouts and styles for, say, the header on different pages, you can use the is_page function to call a different header file depending on which page the user is on.
So to load up a different header on your home page as opposed to any other page, in your index.php (or other page template) add: `if ( is_page('home') ) { echo get_header(home) }`
In this case you'd need a file called "header-home.php" that contains all the necessary code for that custom header, with any classes/id's for items specific to that page so you can style them appropriately.
If you want a quick and easy (but not technically correct) way of doing it, you can just wrap some inline styles in an is_page function, so that those styles are only applied if a user is on that page. But if it were me I'd just load up custom template files to avoid inline styling.
Here's the function reference for is_page() | stackexchange-wordpress | {

a: hover issue with image issues
I am not sure what is wrong but the navigation a:hover has a image that when you hover over it shows. I am looking to see why there is a small space between the end of the image and slideshow. I am wanting to to butt right up to it where there is no gap.
See test board here
< | This isn't a WordPress issue, although it _IS_ an easy CSS fix.
The small space between the end of image and the slideshow is axtually 2 pixels wide and caused by the `#left-area` div.
You can just up the width by 2 pixels on #left-area. Like this:
#left-area {
width: 639px;
}
It is currently 637px.

Use existing image sizes for WooCommerce

Accessing a protected property of a post
> **Fatal error** : Cannot access protected property Some_Plugin::$_some_property
What is the best/least-destructive way of accessing a protected property attached to a post.
The property is being affixed to the post by a plugin but I need to access it's stored information to display.
The options I can think of are:
1. Altering the plug-in code. I'm not so familiar with Object Oriented PHP so I hesitate to do this to avoid damaging the functionality.
2. Somehow invoke the plug-in so I'm in the correct context to retrieve the information (possibly with function in functions.php)
3. Write a function which hooks to the publishing of this post type and duplicates the information to a new, non-protected property of the post.
Does anyone have any suggestions or code samples illustrating the best way to go about this. If you need more information just comment and I'll update the question.
Thanks! | The foolproof method here to grab a dynamic member variable is to use reflection!
Lets say we have this class:
class MyClass {
private $myProperty = true;
}
We can use reflection to acquire the class, and the property:
$class = new ReflectionClass("MyClass");
$property = $class->getProperty("myProperty");
We can then set that property to accessible:
$property->setAccessible(true);
Now we can access the private member variable using the new `$property` object:
$obj = new MyClass();
echo $property->getValue($obj); // Works
Note, that the member variable is still private if we access it directly:
echo $obj->myProperty; // Error
However your code implies a static member variable, e.g.:
class Some_Plugin
private static $_some_property;
}

Wordpress plugin addon
Hey I want to ask a question that maybe sounds stupid but I am new in wp plugin development.
I made a wp plugin that have to do with google maps. I have the basic version thats is free for anyone and i would like to offer especially for the members of my site the opportunity to download some additional features like change the color of the map etc.

I mean me as a developer how can i do this?
Something like a software that when you have an update you don't need to download the whole program but you download the update and load automatic in the existing program.
Thank you :) | You have several options:
## Additional Plugins
Similar to how Gravity forms works, you have the base plugin which is your standard plugin, then you build additional premium plugins that integrate into it using hooks to add additional functionality
## Enabling functionality
Your standard plugin bundles everything inside it, but disables sections of functionality until they're turned on. Turning them on may be via an API key for example
The payment aspects of each solution are going to be very specific to you and how your business model is going to work, so I won't/can't go in to that. Personally I would recommend the plugins route | stackexchange-wordpress | {

I need a standalone script in web root but still have access to the database

However, I need to be able to do wordpress DB calls to get to the data. I have read you can load wp-load.php in the script - will that be enough?
Maybe there is some other (better) way of doing this but wordpress sends headers so I can't output a clean xml file without the wordpress clutter (header footer etc). | You _could_ do that, including `wp-load.php` would bootstrap WordPress and allow you to query the database. I prefer to keep things encapsulated in plugins though, much more portable. You just need to hook early enough to send your own headers, and you can short-circuit the rest of the load process. For example-
function wpd_my_export_script() {
if( isset( $_GET['do_my_export_stuff'] ) ) {
header('Content-Type: application/xml; charset=utf-8');
// do your database stuff
exit;
}
}

Does WordPress refer to any files outside of the main install folder (and database)?
Meaning, if I install WordPress in the /wp folder... would any files in the main root of the domain folder "/" be accessed, or any other folder outside of the /wp folder for that matter? Meaning, are all of the WordPress files continuously self-contained to just the install folder (/wp in my case) and it's subfolders?
(Thus, if this is true, to remove WordPress, can we just delete the install folder...and vice-versa, if we install into a particular folder, we know no other files/folder would be affected?)
Thank you! | The short answer is **no** , WordPress does not refer to any files outside of the main install folder. When WordPress loads (via /wp-load.php), it sets the constant `ABSPATH` to the current directory path and points all further includes relative to that.
However, since you are asking, there are some notable special cases:
* If you install WP in its own directory, you have to copy the `index.php` and `.htaccess` file outside the WP directory to the parent directory.
* WordPress checks if `wp-config.php` exists in its parent directory so you could also have that one outside of the main directory.
* The wp-content, plugins, uploads and theme directory can be moved to pretty much anywhere.

I wonder if its possible to use a template file for a specific url without having to create a page for that template.
This is my simplified problem:
I have created a page in WP with some link content that points to a specific url with some trailing form data: _(mysite.com/retail/?a=test &b=1234)_.
I want that url (retail) to automatically use my template file template-retail.php that I have in the child theme directory, without having to create a page named ”retail” & select the template page from there. There is only external content in the template-retail.php file, nothing from Wordpress itself.
Is this possible? | You can just look at url, load the file and exit.
That can be done when WordPress loaded its environment, e.g. on `'init'`.
add_action('init', function() {
$url_path = trim(parse_url(add_query_arg(array()), PHP_URL_PATH), '/');
if ( $url_path === 'retail' ) {
// load the file if exists
$load = locate_template('template-retail.php', true);
if ($load) {
exit(); // just exit if template was found and loaded
}
}
});
Note that doing so a _real_ page with slug "retail" can never be used.
This is pretty easy, but also hardcoded, so if you need this for a single page it's fine. If you need to control more urls, have a look to the solution proposed in this answer. | stackexchange-wordpress | {

Remove_action from plugin with a Class
I've searched around but haven't been able to find a solution to this. I'm trying to hook in and remove an action that was initiated by a plugin (specifically the Groups plugin). The function itself is contained within a class in the plugin. It basically breaks down like this
class Groups_Registered {
...
public static function init() {
add_action( 'user_register', array( __CLASS__, 'user_register' ) );
}
...
}
Groups_Registered::init();
I've tried to just remove the action, referring back to the class, but it doesn't seem to be working. I've added this to my functions.php file, but it is not removing the action. A
remove_action( 'user_register', array( Groups_Registered::init(), 'user_register' ) );
Anyone know how to solve? I've seen some solutions out there but none of them seem to work. | Just match the callback in your remove call - `array( CLASSNAME, METHOD )`:

Selecting NULL value from the database
I have a database with columns that are allowed to be NULL.
Whenever I run a query against this database using `$wpdb->get_results` the columns that are NULL are always returned with an actual value; the number zero.
In my database NULL and zero actually have totally different meanings and I would like to be able to get the correct values from the database without Wordpress translating the returned value.
How can I select from the database so that NULL values are maintained? | There is no specific issue with retrieving null values from the database. They will come back as the PHP NULL value.
WordPress uses either the function `mysqli_fetch_object` or `mysql_fetch_object` to retrieve results from the database.
< <
According to those respective pages:
> Note: This function sets NULL fields to the PHP NULL value.
Are you using `is_null()` to check for the value? Or are you comparing the result to the NULL constant using the identity check (`===`)? | stackexchange-wordpress | {

How to preview your website without the top WordPress admin bar, but remain signed in?
Is there a way to preview your website without the top WordPress admin bar, but remain signed in?
Basically, want to continue making changes in the panel and review the site, but without the top admin bar...but don't want to sign in every time.

Check If post id exist in custom post type , outside of loop
How can I search in database if id exist in a post type?. I want to search `$id=123` in post type 'movies' like this, is this the correct way to do it?
$content = get_posts('post_type=movies&id=$id');
if ($content)
echo "post id exist";
else
echo "post id doesn't exist"; | You can use:
echo 'movie' === get_post_type( 123 ) ? 'Yes' : 'No';
But if you need to check it many times in your theme, you might consider defining your own helper function:
if( ! function_exists( 'is_movie' ) )
{
function is_movie( $mixed = null )
{
return 'movie' === get_post_type( $mixed );
}
}
It might return true when `$mixed` is empty, `\WP_Post` object or a post ID.
So if you want to know if there exists a _movie_ with ID `123`:
echo is_movie( 123 ) ? 'Yes' : 'No';
or just `is_move()` within the loop, to check the current post ID.
If you only need to check if the ID `123` exists, then just use `get_post()`.
For example:
echo is_null( get_post( 123 ) ) ? 'No' : 'Yes'; | stackexchange-wordpress | {

Can XMLRPC set show_on_front/page_on_front?

All of my wordpress sites showing †Ù¥
This morning I was going to keep working on my Wordpress page, then when I put in the domain name it only showed this: †Ù¥

Most popular post for last 7 days
I need to change the most popular post widgets with date restrictions.

Retrieve contents/page names of various pages for use in a plugin
I'm trying to design a plugin that retrieves the contents of user selected pages and copy the contents into a giant single page. (As long single page websites are trendy right now)
These are the following functions I need to either find or build:
* Get list of page names in database.
* Get contents of the page with page name as the argument.
The pages I am talking about are the user edited pages in the `pages` section of the WordPress.
I'm hoping functions such as these are already apart of WordPress.
I did search WordPress Dev however I couldn't find anything appropriate.
EDIT: I found `get_page()` however the function is now deprecated with the recommendation to use `get_post()`. However does this still work for pages? I thought that a page and post were logically separate entities, for example a different page and post could both share the same ID. Or am I wrong about that? | You can use
* `get_pages()`; or
* `get_posts()`; or
* `WP_Query`
to get a list of pages. They differ somewhat in details, so read up on that. But generally all of them should suffice, for you to achieve your goal. Just choose the best fitting one for your purpose.
For getting pages by name or better `title` you can use:
* `get_page_by_title()`
Or use:
* `get_post()`
if you decide to use the `ID` or the post object.

403 forbidden on one page only

Woocommerce: deleted single-product.php, everything still works. How is it possible?
I'm trying to customize `single-product.php` to achieve the often requested **different categories = different single product templates** , but it seems this file it's not affecting anything at all.
It's like only `content-single-product.php` is doing what it should _(eg. if i customize it, the changes are reflected in the single product pages_ ) and the other files are useless in rendering the single products (!).
I even completely delete all php files in `plugins/woocommerce/templates` folder, and if i leave there **only** `content-single-product.php`, everything still works and every single product is correctly shown!
What am i missing about woocommerce's logic?! | This was happening because of a `woocommerce.php` file in theme's root folder, that was overriding a lot of stuff, including `single-product.php`, via `woocommerce_content()` function.

Disable pagination on frontpage

Track tags in Google Analytics?
I'd like to track tags for our posts in GA. Is there a way to submit them and have them associated the same way they apply in Wordpress, so that you can see how a particular tag is doing?
For example, we would be able to see how all posts tagged "movies" and "Vin Diesel" are doing. This seems like it should be a common enough issue, but I didn't see a great solution in my searching.
Right now our best idea is to submit all the tags in one long string. Then to analyze we have to do a data extract and some manipulation. Is there a better way? | Take a look at custom variables for Google Analytics. In that case you would need to parse all used tags as one string (maybe separated by | for example), because it's better to use one variable name and each variable can take one value per pageview.
Another option would be using events, using a category (named tags for example), which you could repeat for all tags used on a page. I think that is the best solution, since you can fire the same event category multiple times in one pageview. And this way you can search and compare the values within GA easily. | stackexchange-wordpress | {

Migrate posts and photos from a blog to another
i have an old blog that was made by a guy.
Now i'm trying to learn wordpress so i made my own blog, with different theme and template.
I asked my friend to send me a copy of the database of the old blog, so i'll be able to have all my old posts on my new blog.
How can i do that?
I uploaded the database but when i do that it asks me the Admin account of the old blog... but i don't have them and my friend is abroad and he can't help me as of now.
Where do i do wrong? did he do something wrong when he saved the db? Should i change lines in the db file so i will remove the old password? | I'm assuming you have an sql file that you're uploading?
If so, open that file in a text editor such as Notepad. Search for 'user_login', and somewhere nearby that you should see something similar to `'INSERT INTO wp_users (ID,user_login'` etc. On the next line after this, you should see something like `(1, 'admin', 'password'` where 'admin' is the admin username, and 'password' is the hashed password.
You can't login directly with that hashed password. But what you can do here is change the e-mail address listed on that line to one that you can access, then save the file.
Upload it into your Wordpress install again, and this time follow the forgot password link. Enter that e-mail address you put in, and you should be able to reset the password!
Alternatively, you can use an MD5 generator like < enter a new password there and copy the hash to replace the existing password in the SQL file. That will also let you log in with the new password.
