How to split the site's layout without damaging this layout?
I have a site: < and I need to migrate it to wordpress (to be particular, I need in the nearest perspective it's plugins and ability to login thgrough the social networks via wordpress plugins)
I ought to split this design up into header.php, content.php and footer.php without any damaging the content and layout. We don't need to display any posts yet so instead of them should be added a placeholder like an arbitrary article.
Now we're using the Bitrix as a CMS, headroom.js, several inner Bitrix templates which form the current design and they're kind of bulky so we wouldn't like to rewrite all of them.
Is it possible to port this site on wordpress this way as I described? | Better thing is that if you have all pages in html format of you current site , following will help you to convert html to wordpress as per your given partition :

Getting specific image thumbnail urls of attached images
I am using the Manual Image Crop plugin to set thumbnails for images. I am not using any images as 'featured images' however.
I have a number of thumbnails saved to each image. If I use `wp_get_attachment_link(id, 'medium');` then I get the desired 'medium' thumbnail returned but as whole html block output, including '' tags, size etc etc.
I just want the URL of this specific thumbnail (or the img tags 'src' attribute). Is there a built in wordpress function for this or will I have to use PHP regex or something? | Have a look at wp_get_attachment_image_src
<?php
$attachment_id = 8; // attachment ID
$image_attributes = wp_get_attachment_image_src( $attachment_id, 'medium' ); // returns an array
if( $image_attributes ) {
?>
<img src="<?php echo $image_attributes[0]; ?>" width="<?php echo $image_attributes[1]; ?>" height="<?php echo $image_attributes[2]; ?>">

get "read more" with custom DB query like you would with WP Query
I am using a custom database query to fetch posts.
In the post I have a break tag, which is displayed as `<!--more-->` in the database wp_posts table, but I can't get it to output like I would if I used `wp query`. It is basically ignored.
i tried using `apply_filters` like so, but to no avail:
<?php echo apply_filters("the_content", $post->post_content); ?>
I don't get either the "read more" anchor or the "read more" span tag in the post's content.
How can I get it with my custom query? | The `<!-- more -->` tag isn't applied via the `the_content` filter, it's included in the `get_the_content()` function, which checks for the existence of the tag within the content using a regex and then outputs the more link appropriately. this output is filtered via the `the_content_more_link` filter, but since you're not using `get_the_content()` you won't be able to leverage that. you'll need to perform a similar regex replacement in our custom code.

Register Script in Plugin Widget
I need to load a separate js file into a widget and just can't get it to work. So far I have
if ( is_active_widget( false, false, $this->id_base, true ) ) {
function tab_widget_scripts() {
wp_register_script( 'tabs', plugins_url( 'tabs.js', __FILE__ ), array(), false, true );
wp_enqueue_script( 'tabs.js' );
}
}

do_action( 'wp_print_footer_scripts', 'tab_widget_scripts' );
inside `public function widget( $args, $instance )`. Can anyone tell me what I'm doing wrong please? | There are 3 issues.
Firstly, you're calling `do_action`, triggering the action:
do_action( 'wp_print_footer_scripts', 'tab_widget_scripts' );
When actually, you want to add your function to it, not trigger it. You should be doing this:
add_action( 'wp_print_footer_scripts', 'tab_widget_scripts' );
Secondly, you're registering this script:
tabs
Then enqueuing this script:
tabs.js
Clearly they don't match, in the same way that if I give you the ingredients for cake then tell you to make a latte, it isn't going to work.
Thirdly, you only define the function if the widget is shown on the frontend. This is a little odd, instead you should use `add_action` on your function in your widget class, and always define it, saving yourself an unnecessary call to `is_active_widget` | stackexchange-wordpress | {

Display all posts from selected month
I am trying to display all posts from a selected month.
Currently once I select a month, only 10 posts display. I understand I can increase the amount of posts to show under the 'reading' options within the dashboard.
I want to be able to keep the front posts page to display 10 posts but the 'archive' pages to display all posts.
Any help appreciated. | You can use the `pre_get_posts` action to set `posts_per_page` to `-1` on the monthly archive pages.
I said wrongly in a comment to use `is_archive()` as your conditional. The problem with `is_archive()` is, it returns true on all archives, which includes category and taxonomy archive pages as well.
I would suggest to make use of `is_date()` and `is_month()` if you specifically needs to target montly archives

Default taxonomy 'post_tag' added to CPT managing by custom role : nothing in the metabox
I've created a Custom post type, which a custom role can manage : it has only the capabilities for managing this CPT.
When registering the CPT, I've set the argument : 'taxonomies' => array( 'post_tag' ) But when I go to the form of this CPT logged in as a user in the custom role, I can see the Metabox "Tags", but only the title header, there is nothing in the box.
I've not found any capability for giving it to the custom role.... How could this be fixed ?
Thx ! | I guess your custom user role does not have the required capability to assign terms, which in case of the `post_tag` taxonomy would be `edit_post`.
So one thing to do would be giving it to your role--which is most likely not what you would like to do as this does not only affect assigning terms but also a number of other actions).

Adding a query string to only one page url

Why do themes rely on "The Loop"?
I've been looking at Wordpress themes development recently, and I'm trying to understand why Wordpress is coded with "The Loop", rather than providing an array of posts that you can loop through with a foreach.
It just seems to add complexity for theme development, but surely if they went out of there way to create this concept of "loop" there must be a reason? | You are thinking of WordPress templates as PHP application code. Essentially they are not that.
WordPress templates by design are templates using Template Tags API. It is extra level of abstraction, that just happens to allow to use rest of PHP language too.
The ease of template tags serves the popularity of WordPress and extremely low entry bar for people to tweak themes. Believe me, there are plenty of people around who use/tweak loops without much understanding of what they actually are, in extreme cases, what **arrays** even are. | stackexchange-wordpress | {

echo $thiscat->name;

* term_id
* name
* slug
* term_group
* term_taxonomy_id
* taxonomy
* description
* parent
* count

What is the design pattern for WordPress Core?
What is the design pattern of WordPress Core? As this Stack Overflow question shows, WordPress does _not_ follow the MVC pattern; however, developers can write plugins and themes that follow MVC. But my question pertains _exclusively_ to WordPress Core, not to any additional add-ons, themes, extensions, plugins, or forked projects that may or may not follow an MVC pattern.
If WordPress Core does not follow an MVC design, then what design pattern does it follow? | Spaghetti with meatballs
> The term "spaghetti with meatballs" is a pejorative term used in computer science to describe loosely constructed object-oriented programming (OOP) that remains dependent on procedural code.

What happens when WordPress memory limit is exceeded?
Let's say a WordPress website has the following settings:
* PHP Memory Limit: 100MB
* WordPress Memory Limit: 50MB
What happens when the WordPress Memory Limit is exceeded?
1. Do plugins/themes stop / Do processes fail?
2. Does the website hang on the back-end/front-end?
3. Are public website visitors presented error messages or is it all a background affair?
Why is it a bad idea to set it too high? | There isn't really such a thing as _separate_ WP memory limit. It's just a WP way with messing with PHP setting, instead of just using... you know... PHP for that.
* If WP limit is more than PHP limit then WP will attempt to increase PHP limit (which doesn't mean it will succeed at that, but it will try).
* If WP limit is less (such as in your example) then it is simply ignored.
The practical _need_ for a limit is too prevent PHP from draining more memory than server can realistically spare. Hosts usually have hard maximum limit, you won't be able to go above via configuration.
So the answer to your question is — exceeding WP memory limit is meaningless, what matters is exceeding real PHP limit. In which case page will crash with fatal error.
Note that memory limit affects each execution/page view, not a site as a whole. So might be crashing as much as completely everything and as little as one individual page. Whatever is leaking or overusing memory. | stackexchange-wordpress | {

Loading custom CSS
I've done some searching and can't seem to find the appropriate solution for a particular problem I'm having. I've created an option within one of my themes that allows the user to edit any element such as h1, p, divs, etc. The user can also add styling and I basically just build up a string of identifiers and the styling that the user has chosen.
What's the best way to load this css string? Is it best to just have it as a function call before , or should I programmatically create a 'custom.css' file that then gets enqueued after 'style.css'? I worry about creating a 'custom.css' file just in case permissions become an issue. | Well one option you could do, is wrap them in style tag and stuff them into the header via a filter. It's dirty, but it would work. I'd honestly do that, over forcing inline styling on elements, because they won't get cached. Plus anyone who wants to do their own styling to override those elements will hate you.
The cleanest way WOULD be in fact to create a custom.css file dynamically. File Permissions shouldn't be an issue within a theme or plugin environment in MOST installs, however in cases where it is, you can issue a warning to the site admin about it. If you opt for this route, you could do a file permissions check before hand, and default to one of the other methods in the event you don't have adequate permissions. That'd be the most fail-safe way of doing it. | stackexchange-wordpress | {

Displaying custom post types in front end
I am trying to wrap my head around custom post types. What I am trying to achieve is a simple branch listing. There is a dealers menu that has drop downs with regions. When you click on a region I just want it to list branches within the region. Nothing fancy, no maps, just plain text with branch name and contact details + address. Something like this:
Branch Name
Contact Person
Address
Contact number
* * *
Branch Name 2
Contact Person 2
Address 2
Contact number 2
I have used custom post UI plugin and another one that lets me add this data in the backend. I can't for the life of me figure out how to display it in the frontend.
I don't want it to act like a post where it lists everything and you click on it for more detail. It should just display as above when you click on a region from the dropdown. Is there a plugin that would do this or do you have to hard code it? | You can do that easy on this way, just duplicate `single.php` and rename to `single-custom-post-type-name.php` like `single-cars.php`, same thing with archive or taxonomy, `taxonomy-taxonomy-name.php` or `archive-taxonomy-name.php`
Or you can make your query for random page, home or blog:
<?php
// The Query
$query = new WP_Query(array('post_type' => 'your-custom-post'));
query_posts( $query );
// The Loop
while ( $query->have_posts() ) : $query->the_post();
// your post content ( title, excerpt, thumb....)
endwhile;
// Reset Query

Is there a way to display a menu using the ol tag instead of the default ul tag?

Template for product-category page
Where can I find the template that is used for the product-category page? The general template is "page-full.php".

It might just use `index.php` to serve the single page template as well as listings (category, date, author, tag, etc).
The articles Theme Development and Template Hierarchy from the codex should get you on the right road with theme development.
If you add a `single.php` file, WP will use that instead of `index.php` for example.
'product-category.php' (as @ialocin rightly says) is almost certainly a WooCommerce template file and the way you override that is different. They have good docs: <

Redirect not logged in users if they are on a specific page and category

}
}); | In you actual code you can see this:
if ( is_user_logged_in() || ! is_page() ) return;

add_action( 'template_redirect', function() {
if ( is_user_logged_in() ) return;
$restricted = array( 250, 253 ); // all your restricted pages
if ( in_array( get_queried_object_id(), $restricted ) ) {

Plugin Development - Get Admin Url (Including cases where wp-admin is not used)
I'm currently writing a WordPress plugin, and am looking to retrieve the WordPress admin url. It sounds simple enough - and it is - assuming every WordPress install is using the default `wp-admin` slug; I could simply call `get_admin_url()`, which is a wrapper for `get_site_url()`, with `wp-admin` hard-coded (see here: <
However, I don't want to work under an assumption that this url will never change. I'd like to be able to retrieve the url regardless of whether it's default or not; i.e. for either of these cases:
One suggestion has been to allow the plugin user to define the admin url slug, should it be different from the default, but it would be better if there were some way to retrieve it without forcing the user to specify. I'd really appreciate any help on this. | That's why the last line of the `get_admin_url` contains the line:
return apply_filters( 'admin_url', $url, $path, $blog_id );

Custom php file in wordpress
For some purposes i want to have custom php file in my Wordpress that will output content from 3 plugins.
This is the PHP code in the file :
<div class="wrap">
<div class="sidebar1">
<?php dynamic_sidebar('sidebar1'); ?>
</div>
<div class="sidebar2">
<?php get_template_part('sidebar2'); ?>
</div>
<div class="sidebar3">
<?php dynamic_sidebar('sidebar3'); ?>
</div>
However, when i try to open / execute the file i get error like
Fatal error: Call to undefined function dynamic_sidebar() ...
i guess its because i have to include some files to make all the functions / classes available to the custom PHP file.
How can i run this file without errors ? | Andrew Bartel is on the right path, but the link doesn't quite do what you want.
For static PHP files to access WordPress core functionality you need to add this to the top of the PHP file:
define('WP_USE_THEMES', true);
/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

How to change "You must be logged in to post a comment."

Right now it just says "You must be logged in to post a comment." with no link to Login. Where can I edit this and change it to "You must Register or Login to post a comment." with links to them? | You can try to modify it with the `comment_form_defaults` filter:
/**

$fields['must_log_in'] = sprintf(

<a href="%s">Login</a> to post a comment.</p>'
),
wp_registration_url(),
wp_login_url( apply_filters( 'the_permalink', get_permalink() ) )
);

Displaying Content with WP Rest API
I have been spending some time working with the new Rest API. I understand what it is doing but I don't understand how the JSON is used to actually display the content on a page.
I have been fooling around with example.com/wp-json/posts and I see all the code. I can even figure out how to filter them the way I want. What I can't seem to figure out is how do i display this content in a WP post or page?
example: I am using a multisite install and I would like to use 5 of the most recent posts from SITE A on SITE B but I don't understand how all that JSON code is edited and displayed.
I can't seem to find any beginning to end samples on this subject everyone just shows how you grab the content. | I will assume you want to use PHP to display this data directly using a template, there are alternatives such as using another language or actually creating posts via the API.
Simply put you want to take the JSON string and convert it into a PHP object or array using `json_decode`. <
Once the JSON is stored as an object or array you would simply echo or do what you want with the data.
For example:
$json = '{"a":hello,"b":hi,"c":hey,"d":yo,"e":ola}';
$data = json_decode($json);
echo $data->{'a'}
// this should echo the value "hello"
It's important to note to cache external requests, you do not want to make a remote request each time the data is needed, rather you would use the Transient API with a set time for the data to expire and refresh.

Change a custom post type on an existing site
I have a site using two custom post types called destination and walk, where destination is used to categorise walks, by pulling a list of destinations into the walk editor.
Part of the site has now been spun out into it own site dealing with cycling holidays exclusively, but the walk slug is still present in the urls, which is obviously inappropriate.
Does anyone know if and how I can change the url slug for the custom post type without completely busting 90% of the links on the site?
Cheers | Yes, you can change the url slug by searching for the custom post type where it is created i.e register_post_type and change the slug parameter value to whatever you like.You can follow the following steps..
Locate and replace post type slug with any slug you need, try not to use spaces.
1) Just search for slug you need to update.
The script should look like:
'slug' => 'walk'
2) Save the file and test your website.
3) Sometimes you may get 404 error after changing custom post type slug, it is related to permalinks issue. You need to open admin panel, change permalinks structure to default, save website and then revert it to previous state. | stackexchange-wordpress | {

Hide breadcrumbs on specific pages

I'm using the Breadcrumb NavXT plugin. I've only found out how to hide it from the home page.
I'm using this code in my `header.php`:
if ( ! is_front_page() ) {
bcn_display();
} | Suppose you have set up an array of page IDs where you don't want the breadcrumbs to be displayed.
$ids = array( 4, 8, 15, 16, 23, 42 );
Now you just have to check if the currently displayed page (or post) has one of these IDs, and if not, display the breadcrumbs.
if ( ! in_array( get_the_ID(), $ids ) ) {
bcn_display();
}
**// EDIT**
And if you want to exclude pages only--no other (custom) posts--you could speed up the check a bit.
if (
! is_page()
|| ! in_array( get_the_ID(), $ids )
) {
bcn_display();
}

WP_Query - Object manipulation vs WordPress functions
Although this could be opinion based, there must be a some consistent way / optimised way of manipulating data from a `WP_Query`. For example, the 'best' way to get a posts title?
$query = new WP_Query($args);
if ($query->have_posts()) {
while ($query->have_posts()) {
$query->the_post();
$choice1 = get_the_title();
$choice2 = the_title();
$choice3 = $query->post->post_title;
}
}
I'm thinking due to consistency and reduction of function calls, the 3rd option may be a better choice (and a little more consistent since both the `if` and `while` statements use the object notation.)
The third option also gives much greater access to data over the limited number of WordPress functions. Are there any real drawbacks to using it? If not, why bother with the WordPress functions? Sanitation? Error catching? | All 3 of these _could_ do the same thing, it's just a matter of how you want to use them.
`the_title()` calls `get_the_title()` which gets the title by `$post->post_title`.
View `the_title()` Source on Trac
View `get_the_title()` Source on Trac
Personally, I would never use choice 3 as from a readability stand point it's not the most obvious what it's doing. On top of that as Milo points out, you do lose `the_title` filter which is found in `get_the_title()`:
`return apply_filters( 'the_title', $title, $id );`
Choice 1 / 2 are used in different scenarios. You can never assign `the_title()` ( without any parameters ) to a variable because by default it will echo out the title to the screen. The function `get_the_title()` is used to actually assign the title to a variable should you need to run any kind of manipulation on the post title.
You could use any of the choices to achieve the same result it just depends what you're trying to do. | stackexchange-wordpress | {

Image filter works on attachement pages but not posts. I can't get the image ID

Query all post types but limit to parents
I'm building a site with several post types and am using a single `index.php` to query the archive for each one in turn. One of these post types is hierarchical and I'd like to just query the parent. I can use `query_posts` to limit to `'post_parent' => 0` but that creates a new query and resets the post type argument meaning that I'd have to create separate queries for each post type.
Is there a way to limit `while ( have_posts() ) : the_post();` to parents only without creating a new query? | In your functions.php you can create a function that will hook into the pre_get_posts hook. Something like (just an example):
function alter_query($query){
$query->set('post_parent', 0);
}
add_action( 'pre_get_posts', 'alter_query' );
There you can alter the main query. That way while(have_posts()) : the_post(); will still just normally work. (You should check if you are altering the right query and such. Otherwise the post_parent will be applied to all query's by wordpress. You don't want that).
The BIG advantage is, that if you alter the main query, you only have to do that. Wordpress will still select the appriopiate template and such. If you also want to alter the template loaded, you can use the template_redirect hook. | stackexchange-wordpress | {

< | Your problem is that you are putting the page result in $page. While the normal commands like the_title() and get_field() will look for the $post variable if you are not setting a seperate ID of which you want the title.

Then included the .php files, and every normal command like the_title(); & get_field(); works like it would normally would. But this is dirty, and there is probably a much better way to accomplish this.

If you don't do this check, you will get errors on pages that are not taxonomy pages, for instance date archive and category archive pages if they all make use of the archive.php template. The reason is, the queried object varies from page to page, the queried object is diffirent for a taxonomy page than for a date archive page
So you would wrap your queried object inside a `is_tax()` conditional check to make sure that the taxonomy name only displays on the taxonomy page.
To get a complete overview of `get_queried_object()` on a page/template, simply do the following
<?php
$queried_object = get_queried_object();
var_dump( $queried_object );

Correcting the content width when sidebar is inactive?
I want my website's content (posts) to be central in the page when the sidebar is inactive. I've currently got it set to fit both the content AND the sidebar on the same page. How can I make it correct itself if the sidebar is inactive?
I am using get_sidebar();
Here's my website that I'm referring to. | You could try something like this, within your sidebar.php file:
if ( ! is_active_sidebar ('SIDEBAR-NAME-OR-ID' ) ) {
echo '<style>.main-content { width: 960px; }</style>';
}
This is hackish, but it should work for what you're trying to do. There may be a better method but its hard to know without more context. The above code just spits out an inline style rule to full-width your .main-content wrapper _if_ no widgets are present in the sidebar. The wrapper currently is set to 620px in your stylesheet (why it's not full-width). | stackexchange-wordpress | {

html5-reset theme does not show the image

You will need to add full path of the image file to show them in theme. If your image is in theme directory then you will have to use theme directory path variable `bloginfo('stylesheet_directory')` with image name. So this is the code you will need to add in your theme files.

Problems using WP's oembed function + Instagram + AJAX
I am using a modal to load post content via AJAX. Inside the post's template I am using wp_oembed_get() to embed different types of media (YouTube, Vimeo, Flickr, and Instagram). Everything is working, except for Instagram.
When I open a post that contains an Instagram embed, it loads fine. But if I close the modal and try to load another post, the embed does not work correctly. The photo/video within the embed does not load.
This is the page: <
If you open one of the "Instagram Test" posts, close it, then load the other one, you will see what is happening.
I'm at the end of my rope in figuring this out! | Instagram has changed its embed code from being just an `iframe` to a bunch of HTML and a JS script. Very inelegant, but nothing we can do. This setup, of course, fails when called through AJAX since the JS file that's part of the HTML does not run. Thankfully there is another official way to make it work with AJAX in two steps:
1. Include this scripts in your HMTL:
`<script src="//platform.instagram.com/en_US/embeds.js"></script>`
2. Runs this JS after you load the content with AJAX:
`if ( typeof window.instgrm !== 'undefined' ) { window.instgrm.Embeds.process(); }`
What it does is, it looks for Instagram embeds and loads them. Best of luck! | stackexchange-wordpress | {

is_page_template returning false
I'm using woothemes Canvas with a child theme. Additionally, I am using the WP Listings plugin. I am creating a custom listings page template (overriding the plugin template) and I'm having issues recognizing the page type to include scripts/styles on that page type only.
Example:
if ( is_page_template( 'single-listing.php' ) ) {
add_action('wp_enqueue_scripts', 'your_function_name');
function your_function_name() {
the if statement is returning false, although it is using that file. | I think your problem is how your function is constructed and not your condition as such.
You should not be wrapping your function and your action in a condition like this. Page templates are selected really late in the query by the main query, and I probably think that this is way to late for your action to execute. By the time the condition hits true, the `wp_enqueue_scripts` hook already executed and cannot be rerun
If this is a single page, and that single page is for a custom post type called `listing`, you should be using `is_singular( 'listing' )` instead of `is_page_template()`
The correct way would be to wrap your scripts and styles inside your function inside your condition
You can try the following
add_action( 'wp_enqueue_scripts', 'your_function_name' );
function your_function_name() {
if( is_singular( 'listing' ) {
// add your scripts and styles

Correct way to pass information between seperate shortcode functions
I contain all my short-codes in (the equivalent of) `functions.php`. I want to have one short-code function share information in an object, and another able to access that object. The shortcodes may or may not be on a page together.
I was thinking a unique `global $obj` rather than using `global $post`.
What is the 'correct' method in Wordpress? | The correct way is not to do it. Shortcodes are supposed to be self contained and represent an insertion point to some complicated HTML that is harder to get right or due to security permissions is impossible to insert in its pure HTML form.
Globals are hated magic when you write proper code, now think about plain text, how exactly the non technical writer can even guess that one shortcode is depending on the other, and what will be the result of removing one of them?
if the second shortcode needs to know the attributes passed to the first, just document that the user should pass the same parameters to both. | stackexchange-wordpress | {

Loading page content into a variable in template
On one of my custom templates, I need to do some work with the content before displaying it. Is there a way that I can load this content into a variable rather than just outputting it to the page?
This is what I've tried but it only outputs the page content, it doesn't load it into the variable.
$content = get_template_part( 'content', 'page'); | You can always use the output buffering to store the printing contents in a variable.
function return_get_template_part($slug, $name=null) {
ob_start();
get_template_part($slug, $name);
$content = ob_get_contents();
ob_end_clean();
return $content;
}
$content = return_get_template_part('content', 'page');
This would be most preferable to keep using the get_template_part() right now. An alternative would be to use locate_template() function but it would compromise the use the default templates.

Admin Filter - Add Post Type Description on Post Type Page

With all plugins disabled, the error does not happen. If I enable, for example, revolution slider, the error occurs. However, I believe more than one plugin or a combination of plugins might be causing the problem.

My guess is that your uploader fails on uploading big files with more serious plugins on just because they are using some of the memory too. In some cases "Memory exhausted" message does not appear if you don't have the right server settings.

Shortcodes in custom post fields without the_content()
I have created a custom post type which doesn't use `the_content()` to display anything in the front-end, just using echo's.
The user enters data into a text-area field in the plugin admin back-end, the CPT does some data manipulation and everything is output through a template file using a shortcode.
How can I get short-codes to fire when a user enters them into a CPT text-area in the backend admin. I can't see any filters being used. Also since it's an admin area text input field, php snippets won't work.

Perhaps a better question is how to implement `the_loop` properly in a custom post? My code currently;
<?php
/*
Template Name: Article
*/
?>
<article class="article-single">
<?php
echo do_shortcode('[banner]');
... loads of shortcodes to build up html...
echo do_shortcode('[info]');
?>
</article> | I ended up writing a basic function which used `preg_match_all` and `preg_replace` to find my short-code tags and sanitize the content before building the HTML output for the template page.
In my case, only useful if you have the one short tag being used.
function img_strip($str)
{
$preg = '/\\bimg\b\\[\/\bimg\b\]/';
preg_match_all($preg, $str, $matches);
if ($matches) {
foreach ($matches[1] as $match) {
$parsed = parse_url($match);
if (empty( $parsed['scheme'])) {
$match = '//' . ltrim($match, '/');
}
$replace = '<img src="' . $match . '" alt="floating-image" class="image">';
$str = preg_replace($preg, $replace, $str, 1);
