Children Shortcodes?
I started creating WordPress plugins a few weeks ago, and I would like to know if it's possible to somehow "embed" shortcodes in some others. Basically what I want to do is create a table or a list, based on a set of items entered by the user of the plugin. Is it possible to have something like :
[data]
[item1] something [/item1]
[item2] something else[/item2]
[item3] something else[/item3]
[/data]
In short, I want to create something based on the elements contained in the _itemX_ "children" shortcodes. Is there any way to do something like that?
Thanks | This is possible, but you can only nest one level down, after that the shortcode regexp parser flips out. So your example would be okay, but [item1] would not be able to contain even more nested shortcodes.
To enable nesting, just go ahead and do:
add_shortcode('data', function($attributes, $content='')
{
return do_shortcode($content);
}

Error showing in current page id in wordpress admin
I am trying to remove a metabox ID from a page ID in the admin screen. So I have coded the following:
function ag_remove_cmb_metaboxes() {
global $post;
$id = $post->ID;
if ($id == 21) { ?>
<script type="text/javascript">
jQuery(document).ready(function($){
jQuery('#test_metabox_img') .hide();
});
</script>
<?php }
}
add_action( 'admin_head', 'ag_remove_cmb_metaboxes' );
It is working fine but an error is showing in the widget.php page. Error code is:
> Notice: Trying to get property of non-object in E:\xampp\htdocs\speechcare\wp-content\themes\cutedoctor\core\helpers.php on line 56
Can anyone please explain why this error is showing and what I am doing wrong? Thanks in advance. | While front–end of the site always has a post context (you are either looking at one or archive of posts), admin side doesn't.
So plenty of admin screens won't have `$post` global set to anything. You should be checking if it's meaningful (for example by `if ( ! empty( $post ) )`) before trying to access it. | stackexchange-wordpress | {

Wordpress search issue with searching html tags
I am working on a wordpress site and I am using wordpress native search. When we search for a string like "example" it searches inside html tags. ie if there is any html tag like `<a href=" in the page or post then the search result will show that particular page or post. I dont want to search inside html tags.
I already tried using the plugin Search Exclude HTML Tags But it uses MySql stored function which is not working for me. I think it may be issue with the permission of my mysql user.
Is there any alternate way to fix this.

User gets access denied to css files and js files even though user is logged in
We are using wordpress as a intranet, we have the AD Integration plugin. Everything is working fine except for one user. Now there is no difference in settings on his machine or user profile or AD profile to any other user. But for some reason when he logs in he gets access denied to all the CSS files and JS files.
I know he has logged in successfully because I use console.log to display the username when logged in as well as other details such as full name and job title. The details are retrieved from the wordpress function for current_user so I know he is logged in. Has anyone else had issues with style sheets etc being denied even though the user is logged in?! | In most typical WordPress configurations the load of CSS/JS assets is _not_ actually processed by WordPress core. Otherwise the performance would be _horrible_.
Web servers do fantastic work at serving static files like that though, so WP's configuration (`.htaccess` or other, depending on server) just passes all such files to them.
It's not clear from your description:
* if that user can access files when _not_ logged in
* if _specific_ files cannot be accessed or definitely _all_ files
WP admin uses PHP for concatenation of assets, which does tend to cause issues now then. You can try setting `SCRIPT_DEBUG` constant to `true` in configuration to disable it (as well as minified versions) and see if that makes a difference.
But for completely static assets this is unlikely to be caused by WordPress core in general. Check server logs for clues, especially if you are running security and/or firewall modules on it. | stackexchange-wordpress | {

How to use PHP code with wordpress page
new user to WP. I am dynamically creating HTML tables with SQL data in my PHP. WordPress pages do not allow PHP code, and I've been hounded by individuals not to use a PHP plugin due to security reasons.
Now if i just needed to run a PHP file i would simply include it inside of my custom page-template. Since the code needs to be displayed inside the "content container" (which is dynamically loaded) I don't fully understand where to place my code.
<?php get_template_part( 'content', 'page' ); ?>
I've noticed this code above is calling the content container for that page. Should i be loading a different page here? or should i be directly modifying the page data inside the DB to reflect my php? will this work? whats the best thing to do in my situation? | The best way to create dynamic data outputs really depends on the what, why, and how.
For example, if you're creating a theme that creates its own custom post type, say, to store information about the head honchos that run the business behind the site, then just create a "single-$CPTNAME.php" template that has the code that you want.
Another method of doing this would be to create a custom template, and simply select that for a given page. See the WordPress Page Templates documentation for more information on how to create the custom templates and make them selectable in the WordPress admin UI. | stackexchange-wordpress | {

How to overwrite orderby with add_query_var
So I would like to have an archive that displays its posts in a random order.
<?php
$query = new WP_Query($query_string."&orderby=rand");
?>
But also then if the user chooses they can order the posts differently by clicking a button.
<?php
$sort_date = add_query_arg(array('orderby'=>'date','order'=>'asc'));
$sort_name = add_query_arg(array('orderby'=>'title','order'=>'asc'));
?>
<div class="sort">
Sort by: <a href="<?php echo $sort_date; ?>">Date Listed</a> | <a href="<?php echo $sort_name; ?>">Name</a>

if(
$query->is_main_query() &&

Display pages in alphabetical order
I think I am missing something in my `functions.php` because my pages in the admin are displayed randomly. How can you display the pages in admin alphabetically?
Thanks! | Filter `pre_get_posts` is used for modifying the query from theme or plugin. This hook is called after the query variable object is created, but before the actual query is run.
Codex documentation of `pre_get_posts`
Although this filter is very handy and useful, we need to be very careful using it. We should very careful about targeting the query. This filter is applied for both front end and back end admin panel. WordPress provides several conditional function which can be used to target the specific page.
* is_main_query()
* is_admin()
* is_home()
* is_post_type_archive()
* and many more
See here for more conditional tags
Example, if you want to target only home page then you can use like this:
function my_custom_function( $query ) {
if ( $query->is_home() && $query->is_main_query() && !is_admin() ) {
//change query parameter here for home page

How to retrieve the date on which a post was moved to trash?

The following code allows me to retrieve posts that are in trash, but how to filter them by date?
$options = array(
'post_status' => 'trash',
'post_type' => 'post',
'nopaging' => TRUE
);
$wp_query = new WP_Query();
$posts = $wp_query->query( $options ); | When post is trashed, WP creates a meta field named `_wp_trash_meta_time` and it saves trashed time in that field. You can use that field to get trash time.

Example:
$args = array(
'post_status' => 'trash',
'post_type' => 'post',
'nopaging' => TRUE,
'meta_query' => array(
array(
'key' => '_wp_trash_meta_time',
'value' => array( strtotime("last week"), date('U') ),
'compare' => 'BETWEEN',
),
),

WP Query Exclude and Start by Menu Order Offset

Where is the old post permalink slug stored?

Then I search for other posts with the `writing` value, none found.

Display future posts in archive
I'm using the following code to display an archive of posts.
<?php
// Get years that have posts
$years = $wpdb->get_results( "SELECT YEAR(post_date) AS year FROM wp_posts WHERE post_type = 'post' AND post_status = 'publish' GROUP BY year DESC" );

foreach ( $posts_this_year as $post ) {
// echoing miscellaneous stuff

change $src from wp_register_script in plugins/themes

Timthumb not working with WordPress 4.0

Is there any way to tell when wp_postmeta has been updated?

Use one template only for custom post type archives?
I'm currently using `archive.php` as a generic listing for categories, tags, authors, etc. However, my custom post types have a very customized archive page that's completely different from `archive.php`.
I'm wondering if there's a way to create one archive file that acts as a generic template for **only** my custom post types. If it was included in the Template Hierarchy, it would likely be called `archive-post-type.php` or `post-type.php`.
I know I can use includes or `get_template_part`, but it's really just the same archive file across multiple post types, so I'd rather just create one file for all of them. Ideally, this CPT archive template could still be overridden by `archive-$posttype.php`.
If I utilized `archive.php` instead for the custom post types, I'd have the same problem in reverse, since `category.php`, `tag.php`, `date.php`, etc. would all be the same template, yet still different from `archive.php`. | add_filter( 'template_include', 'wpsites_cpt_archive_page_template', 99 );

return $new_template ;
}
}

Try this in your functions file.

Make slug as ID Number for custom post types

FA3
FA10
Is there any way of acheiving this with `WP_Query`? (Or is the only option to create an array and sort that array with `nsort()`) | No, not as a straight WP_Query. This is because of several factors, with the main one being that mySQL doesn't natively have a natural sort for alphanumeric columns.
WordPress does support a "meta_value_num" for the orderby parameter, which causes it to cast the values to numeric to perform the sort, and this works when you're putting wholly numeric data in the meta_value's, but since you have a mixed set of text and numbers, you can't use that.
You can add a filter to the `posts_orderby` and rewrite the orderby clause directly to make it whatever you like. If your data is always going to start with "FA", then you could make your filter return something like this:
`LENGTH(meta_value) ASC, meta_value ASC`
That first sorts by the length, then by the value. So shorter items come first, giving you a semi-natural sort. | stackexchange-wordpress | {

* WordPress Database Access Abstraction Object

* It is possible to replace this class with your own
* by setting the $wpdb global variable in wp-content/db.php
* file to your class. The wpdb class will still be included,
* so you can extend it or simply use your own.
I was wondering how replacing the wpdb class with a different class would work but I cannot find any file under wp-content/db.php. Is there an error in the documentation?
Thanks. | You would create your own `dp.php` file in the `wp-content` directory; if you define `$wpdb` in there, it will replace WordPress's default `$wpdb` object.
It's not listed on the Pluggable Functions list (not a big surprise, as `$wpdb` is a class, not a function), but it seems similar in concept.
Also, if you haven't read it yet, I'd recommend you peruse the WPDB Class documentation. | stackexchange-wordpress | {

add_image_size() width not actually working
I've been attempting to add an image size to my code, for an image that needs to be 708px wide. Height can be variable. I've added the code this way:
add_image_size( 'full-blog-width', 708 );
add_filter( 'image_size_names_choose', 'my_custom_sizes' );
function my_custom_sizes( $sizes ) {
return array_merge( $sizes, array(
'full-blog-width' => __( 'Full Blog Width' ),
) );
}
However, when I go to add the images in the media library, the width seems to max out at 474px with the height varied based on proportions. I've attempted hard cropping, but that doesn't seem to affect anything but the ratio in the end. Best I can tell, this 474 number comes from the is the width of the blog post container. Does the media library set a maximum size for the images based off the blog post CSS? Is there a way to override this? | > After playing around a little more, the image does look like it's being resized by wordpress on upload to the 708 width, however, when inserted by the media library, the image is automatically scaled down to 474px which is the width of the text column.
This is correct. Themes define a global variable called "$content_width" which tells WordPress the width of the main displayable content area. WordPress will automatically put images into a container with this width, so as to not overflow the content area.
The resizing of images on upload is independent of this process. The image will be whatever sizes are defined for it, but it will scale into the space provided for it by the content width. | stackexchange-wordpress | {

Make single widget area top level in 4.0 Customize Panel
So I have a widget area that, in v4.0, is burried in a dropdown within the secondary Widgets panel on the Customize panel page.
Because it's the only widget area it feels rather silly being burried so deeply, so I'm wondering if there's a way to override the nesting and make that widget area dropdown a top-level section like it was in v3.x?
It looks like this was brought up by the Core team here, but didn't gain any traction.
Does anyone know how I might be able to do this? | Got it.

// "the_widgets_section" in get_section is the ID of the registered widget area
$widget_area = (object) $wp_customize->get_section( 'sidebar-widgets-the_widgets_section' )
// The value of panel will be 'widgets', so we set it back to '' (top level panel)
$widget_area->panel = '';
// If you're so inclined, we can change the title of it as well.

Is there any way to recover deleted menu from database sql backup
i accidently deleted my main menu but i have a .sql database backup file and i want to recover my menu from this file. Is it possible? Thanks. | I've resolved the problem with explained here : <

So _conceptually_ it probably would have been protected in modern code (then it would probably need getters, because these two properties are highly useful for debug).

Updating options into the wp database performance
I have a question about the performance of my plugin.
On the settings page of my plugin I have about 20 options the user can change (checkboxes, dropdown and normal text inputs). Currently I just update all options on submitting the form.
Is it better for performance to first check if an option is updated before I really update the option? So that it doesn't write to the database if the option isn't changed? | `update_option()` does this for you already:
// If the new and old values are the same, no need to update.
if ( $value === $old_value )
return false;

array(
'after' => 'midnight 2 days ago',
'inclusive' => true,

Page not found error shown while installing wordpress on IIS server

what to backup (for partial restore)??
My site has hacked three times, and as forced by host provider, now there is no option in front of me, except restoring a healthy backup for around 3 weeks ago.

Thanks in advance (and sorry for bad english) | To backup only posts,pages and related media files for 3 week.
You need to do the following:-
1. Backup Database of website for post/page text.
2. Backup wp-content\uploads folder for media.
Then you can delete all files and restore old files.Once all old files uploaded then you can upload wp-content\uploads folder of current site.
PS: check uploads and folders in it for any backdoor code.

Once restoration is done install Anti-Malware WordPress plugin and scan for any malware files in them. It is better plugin. | stackexchange-wordpress | {

At what point during a typical request does the $wpdb object become available?
I've wrote some custom SQL queries inside a class method and noticed they seem to work if I hook the method to the `wp` action. If I hook to the `plugins_loaded` action, they don't seem to work.

At what point during a typical request does the `$wpdb` object become available?
Refs:
* <
* < | Please, post your code because the problem is not the one you guessed.
Actually, `$wpdb` is available very early: it is inited by the function `require_wp_db()` located in the file `wp_settings.php` at line #79.
The hook `'plugins_loaded'` is fired in the same `wp_settings.php` file, but at line #237, so pretty after `$wpdb` is available. | stackexchange-wordpress | {

getting image alt text via ACF plugin in WordPress

`<img alt="" src="<?php the_field('slideshow_image'); ?>" />`
I am trying to pull in the image alt text, which I have stored in `wp_postmeta` under the `_wp_attachment_image_alt` metakey...however, i'm not sure how to access this. Calling `the_field` with "image_alt" does not work and there is limited documentation. | You need to set your ACF field to return the image object instead of the URL. You can then use the following code to retrieve the image and alt text:
<?php $slideshow_image = get_field('slideshow_image');
// Check for alt text - if there isn't any, use the image title
$alt = ($slideshow_image['alt']?$slideshow_image['alt']:$slideshow_image['title']);
// Return full size image
$url = $slideshow_image['url']; ?>
<img src="<?php echo $url; ?>" alt="<?php echo $alt; ?>" />
If you want to return the image at a different size, you can use the sizes array instead of the url:
// Return image thumbnail
$url = $slideshow_image['sizes']['thumbnail'];
Documentation here under Customized display: <
EDIT:
This solution works for ACF 3.3.7 and above only. Another method is to return the image/attachment ID, then use `wp_get_attachment_image()` to return the full image HTML. Documentation here: < | stackexchange-wordpress | {

wp_kses_post only removes <script> tags, but not their content
Is there any way to remove the `<script>` tags including their contents?
wp_kses_post seems to only remove the tags, while their content remains visible on the page.
Thank you | KSES is designed to prevent execution of undesired and potentially dangerous tags, not preventing display of the innerHTML. Blocking the content would require
\--1 Either a custom function that used some kind of string manipulation or xmlDOM manipulation to remove content; or
\--2 A function that blocked posts that contain the tag with a message why the post failed and instructions for using HTML codes to render script tag when using it in tutorials rather than as an execution tag.
Number 1 may produce performance issues with its higher overhead. If optimizing performance is an issue or if the site involves heavy posting by multiple users, then #2 is likely a more feasible solution. | stackexchange-wordpress | {

Using wp_register_style to load CSS in footer?
I realise you can enqueue JS in the footer using `wp_register_script` as there is a `$in_footer` parameter for doing so. However, there isn't one for `wp_register_style` it seems.
Is there a way to enqueue CSS in the footer in the same way, or do I have to manually hardcode the file path in my footer.php file? | Technically styles should only be output in head and outputting them elsewhere is invalid HTML (browsers are however very lax about it and don't care much).
So in best interest of standards WordPress wouldn't do something like that. Right? Right!?
It does without bit of remorse actually. There is `print_late_styles()` function, running in footer that will output any queued styles that hadn't appeared in the header.
So while there is no explicit way to enqueue style for footer (like for scripts), simply adding them into queue after header had passed will make them appear there.

Change standard post format metabox
I added a meta box to my theme (WordPress admin) for video, image, gallery and chat, but I can't add a meta box for the standard post.
When I add post type support for "Standard", the standard post format in admin is duplicated. When selecting the 2nd "Standard" from the list, a meta box is added, but it should do that for the 1st "Standard" and not show it twice.
!enter image description here | The problem you are having here is that `standard` is **not** a post format. `standard` is just assigned to posts that does not have a post format assigned to it. You can also check in your db in `wp_terms`, there is no `post-format-standard` term. You can also do the following to print out a list of all registered post formats
$terms = get_terms('post_format','hide_empty=0');
?><pre><?php var_dump($terms); ?></pre><?php
This is actually one flaw in the post format system. I don't know if this was done on purpose. Unfortunately, you can't add new post formats. So you can't register a `standard` post format.

This actually _is_ `robots.txt`. :) That is what rules in it look like.
If your installation doesn't have physical `robots.txt` file than WordPress will be serving virtual one, using `do_robots()` to generate it.
