Auto crop images in Wordpress
Im brand new to coding in wordpress, usually I use ModX. In ModX there is a plugin called phpthumb which automatically crops images to a specified h and w. How can I achieve this in Wordpress?
Image Code:
<?php
$thumbnail_id = get_post_thumbnail_id($post->ID);
$thumbnail = wp_get_attachment_image_src($thumbnail_id,'featured works');
echo '<div data-src="'.$thumbnail[0].'" alt="[[+name]]"></div>';
?>
Thanks for any insight. | You can use `add_image_size` to create your custom size like this:
add_image_size( 'featured-works', 220, 180, true );
then get it like this:
wp_get_attachment_image_src($thumbnail_id,'featured-works');
take into account how the crop works here | stackexchange-wordpress | {

Eliminate render-blocking JavaScript and CSS in above-the-fold content
I am optimizing speed of my website and fixed all issues except "Eliminate render-blocking JavaScript and CSS in above-the-fold content".I have gone throgh many solutions but not resolved till now.
![enter image description here]( | In most cases this won't actually increase your speed by much but will make your site design "flash" in and look bad. If your site is fast then ignore this notice (search engines care about actual speed not "scores") and most websites do not defer the CSS because it makes the site render not as nicely and as long as you aren't loading JS from 3rd party API's it won't make much difference anyway (themes should be loading scrips from WP core or the theme so usually it's fine).
Of course if you really want to there are plugins for that or you can use custom code. Here is a good tutorial - < \- just be careful because some themes and plugins purposely add JS to the header because it's needed early on. | stackexchange-wordpress | {

Why is file_get_contents returning page source?
I'm trying to write a shortcode in my theme's **functions.php** file that can display the contents of a CSV file on our server.

PHP syntax error when using wpdb update?
I'm not too good with PHP, so I'm having trouble with some code that is supposed to update the wp_posts table. The problem is that when I try to save it, WP deactivates the plugin saying there's a syntax error in the following bit of code:

$dbresult = $wpdb->update($wpdb->post, ['post_title' => 'Test Title', 'post_content' => 'Test Content', 'group_access' => $group_access, 'tag_list' => $tag_list], ['ID' => 12095])) :
if (false === $dbresult) {
echo 'An error occurred wile updating...');$errors = $post_id->get_error_messages();
}
I believe it would work if I could figure out what the syntax error was. | you've got a simple typo, it should read
$dbresult = $wpdb->update($wpdb->posts, ...) ;

Custom posts don't work
I made a basic custom post type basing on examples from codex but it doesn't work until I modify permalink settings. When I click `view` to preview the post I see `Not found` notification but when I modify permalink settings, click `Save changes` the post works as well as default post type. I mean, without creating special loop queries.
What should I do to avoid this error creating a theme to public use or selling?
Do everyone will have to change permalink settings to be able to use my custom post types? | After custom post type registration, that is `register_post_type()` , try adding function `flash_rewrite_rules();`
This will automatically flush all rewrite rules so you won't need to go to permalink settings each time.
See this page: <
Example:
add_action( 'init', 'my_cpt_init' );
function my_cpt_init() {
register_post_type( ... );
flush_rewrite_rules();
}

What does wp_update_post() do that the $wpdb class does not?
I recently had to make direct changes to my `wp_posts` table from a WordPress plugin. I first tried to do this with `wp_update_post()`, thinking that would would do it. Apparently, `wp_update_post()` is only able to edit a predefined set of table fields (presumably the WP default ones). Then I happened upon `$wpdb` class. I thought I read that `wp_update_post()` uses `$wpdb` which is interesting, but then begs the question, why have `wp_update_post()` when you can just use the `$wpdb` class directly? What does `wp_update_post()` do that the `$wpdb` does not? What need is it filling? Or is it more of an administration concern, like resources or security? If that's the case, what are the downsides of using $wpdb directly? | 1. `wp_update_post()` calls some hooks that `$wpdb` doesn't on it's own. You'll have to do it on your own to make it compatible with other plugins.
2. `wp_update_post()` calls some functions related to database entry sanitation, thumbnails, attachments, time (format, zone etc.), comment, taxonomy, meta, cache etc. So if you use `$wpdb`, make sure you handle all of them as appropriate.
3. WordPress will update `wp_update_post()` to always keep it compatible with the current state of Database, core CODE, plugin support etc. Even if you do everything right, future updates will be difficult for you with `$wpdb`.
So if something can be done with `wp_update_post()`, then always use it, only use `$wpdb` if your desired action related to updating post can't be done with it. | stackexchange-wordpress | {

get_tags() return an empty array after added tags with wp_insert_term()

array('name' => 'Group Holidays', 'slug' => 'group-holidays'),

foreach ($tags as $tag) {
if (!term_exists($tag['name'], 'post_tag')) {
wp_insert_term($tag['name'], 'post_tag', array('slug' => $tag['slug']));
}
}
display.php
$tags = get_tags();
var_dump($tags); // empty array()
Am I doing something wrong? | Thanks to @Milo I could fix it. The problem was, that the tags were not assigned to any post.

Disable a Wordpress site
Hello I plan to disable my wordpress website. I don't plan to permanently delete it from the web. What are the steps I must follow to disable it? | An easy way is to create a file called 'maintenance' and place it in your sites root folder. When WP sees that file, it puts up a 'down for maintenance' type file. You can still get into the admin area, but the 'public' can't see the file.
Another way is to rename the '.htaccess' file (which helps redirect access to the site into WP pages) and create a new index.php/html file (renaming any existing one). That index file would contain an 'under construction' message or something similar. Disadvantage of that would be no access to the admin area.
Which technique you use depends on the length of the downtime. Temporary downtime: I'd use the 'maintenance' file technique. Longer-term: I'd build an 'under construction' page as index.html or index.php (renaming any existing files of that name) and rename the '.htaccess' file. | stackexchange-wordpress | {

Could a higher number of registered image sizes affect performance?
This question is related to this one, but is a bit different.
In the layout (archive page) for a Wordpress project I'm working on right now there's a couple of image sizes that do not appear anywhere else. They are quite (by tens of pixels) close to the sizes that we already have registered — let's say, we have 210x300 already and the new size is 230x300. There's also another new image size which doubles that in height and could be also replaced by an already existing image size.
I know that having a lot of differently sized elements might not be good in terms of design consistency — so that could be one argument against it.
But, looking more from a practical side, are there any performance related concerns in adding more and more image sizes via `add_image_size`? Currently we have 8 custom image sizes, and I'm not sure whether it's optimal to add more of them.
Thanks! | Depends. One argument could be that if the requested page use all sizes then there will be a lot of image calls (slower response, bandwidth etc) but you can bypass that i.e. by loading images with JS. Also more sizes means more disk space usage. I don't think there is any significant performance concern related to back-end, meaning the db calls / queries etc.
Also if the images are compressed from the begging a few pixels down in width or height won't be a difference in performance.
You can have an image with 600x900 dimension and cover a lot of intermediate sizes adjusting with CSS and keep a good aspect ratio and have a good quality for retina monitors. Better to have a bigger, in dimension, image and shrink it than to have a smaller image and scale it up. | stackexchange-wordpress | {

My style in my child theme loads after the parent theme, but it breaks stuff: How do I load it before the parent theme?

}
add_action( 'wp_enqueue_scripts', 'bla_enqueue_child_theme_styles', -20); | > How do I load it before the parent theme?
I think you are doing it right. If the parent theme is attaching the function responsible for enqueueing its styles to the `wp_enqueue_scripts` hook, then your `bla_enqueue_child_theme_styles()` function must be being executed first (because you passed `-20` as priority) and your styles should be being included first in the page's source code.
The fact that Materialize's CSS rules are overriding the parent theme's may not be related to the order in which the stylesheets are being included, but to the specificity of the selectors being used in those stylesheets.
Cake is likely to be using some kind of CSS framework as well, either one developed by a third party or a custom one. In that case, is very likely that both Cake and Materialize are trying to solve the same problems, but using different methods, creating conflicts in the process. | stackexchange-wordpress | {

Duplicated WP site manually, now links redirect wrong
So, I duplicated my website (by just duplicating the VM in Proxmox under another name) so I could use the local duplicate to test settings and develop the site. I have edited the database, changed the site URL from wp-config.php and everything kind of seems to work.

REST API, get user role?
I'm trying to figure out how to retrieve a user's roles from the API, but I haven't been able to sort it. Is this information not accessible by default?

'schema' => array(
'type' => 'array'
)
));

At the moment I'm using the `register_rest_field()` function, but it allows me to chose only the type of object.
Do you know if there is a workaround to this issue? Or do you know better ways to reach the same result?
P.S. I'm using WP 4.7.3 | I found a better workaround using the same filter suggested by @ben-casey in his answer.

I have a Bootstrap 4 slider in progress at < . When I add images of a 0.75 ratio like 2000x1500 they display and resize well. 3000x2000 works too. This with them being loaded with:
`the_post_thumbnail('post-thumbnail', ['class' => 'img-responsive responsive--full', 'title' => 'Feature image']);`
It seems to show the images the way I cropped them in WordPress or not and then load them with file dimensions that vary from image to image.
When I use `add_image_size( 'b4-slider', 2000, 1500);` or `add_image_size( 'b4-slider', 2000, 1500, true);` because I am like, let's automate setting the proper size for these babies.. they are no longer responsive. They get squashed when I shrink the browser window size.
How is this possible? | Hmm, I figured it out. I changed the thumbnail AND removed the needed class img-responsive to apply responsive dimensions. Once I kept those all was fine. – | stackexchange-wordpress | {

How do you use JavaScript to detect the homepage
I have tried is_front_page() but I believe that is the php way of doing it. Perhaps I'm not calling it right because, of course, I'm not getting a response. Maybe I'm just short of my detailed Js ways of accessing the Wordpress classes.
What I'm trying to do is simple. If I am on the front page or home page add this class if I'm not add this other class. Very simple it's just not working. I have even tried a pseudo span tag and add the class to that and it doesn't work. | I just posted an answer to another question about how to do it.
In your case, assuming you used `body_class()` in your theme, your home page should have a `<body>` with class `home` to it.
So in your JS, you can:
if( $('body.home').length ){
// Do stuff

Why use hierarchical taxonomies instead of many custom taxonomies?
Or vice versa. What reasons are there for choose one over the other?
![hierarchical taxonomies](
vs
![multiple custom taxonomies](
I realize the examples I gave may not be the best dummy data, but pretend, in this instance, that I have a blog for animal pictures. A single post could have both dogs and cats.
Performance? Issues trying to use Prev and Next links? URL structure? Or would both options be practically the same? | If you needed an archive page that listed all dogs, then the hierarchical approach would be much efficient. You could visit `/category/dogs', and Bob's your uncle.

Why wp_enqueue_style() not working?

Editing pages from dashboard
I keep struggling to understand how and why this happens: in some themes I can modify the content of a page (type page) from the dashboard, in others I can't. For instance, if I activate a default theme, say Twenty Fifteen, I can create and edit pages from dashboard.

Wordpress behind Proxy - Mixed Content
My Server Env for a wordpress site is as follows:
---------- --------- -------------
| Client | <-- HTTPS --> | Proxy | <-- HTTP --> | Wordpress |
---------- --------- -------------
The Problem is that the Wordpress Site itself is served internally over HTTP but the Client communicates over HTTPS with the Proxy. Since Wordpress is configured with HTTP it returns links and images-src with " which leads to `mixed-content` errors in the browsers.

undesrtanding get_post_meta function
Is there any way to avoid that when you don’t specify a $key ('') and set $single to true in get_post_meta, it returns all keys still with an array of values, instead of returning a single value only .
$meta = get_post_meta(get_the_ID(), '', true);
print_r($meta);
//This is giving me:
//Array ( [key_1] => Array ( [0] => value_1 ), [key_2] => Array ( [0] => value_2 ) )
//And I will expect:
//Array ( [key_1] => value_1, [key_2] => value_2 )
I know that I can access the data writing array[key_1][0], but I don't understand why, considering that I'm declaring $single as TRUE.
I might be missing something... | `get_post_meta()` calls get_metadata(), the parameter description of which says:
> $single (bool) (Optional) If true, return only the first value of the specified meta_key. This parameter has no effect if meta_key is not specified.
>
> Default value: false
So, since you are passing `''` as the meta_key, the `$single` parameter is ignored.
Does that explain it?
**Edit:**
If you only want the 1st value for each meta key, then just do the following:

background changed after Wordpress update

The following has only been tested in 4.7.3 (and I never use custom backgrounds in the customizer, so I'm not sure what previous version of WP did there).
In the customizer, when you set the custom background image, there should be an "Image Size" dropdown. You probably have "Original Size" selected in this dropdown. If you change that to either "Fit to Screen" or "Full Screen" you should get what you want.
Which one you choose depends on what you want to achieve. "Fit to Screen" results in the customizer outputing `background-size: contain ;`, while "Full Screen" results in `background-size: cover ;`.

* `$wp_the_query` is the variable that holds an unmodified copy of the global query object and used to reset the `$wp_query` object when we call wp_reset_query()

How can I insert a shortcode in the title tag of another?
//Shortcode which return a name
[get_name]
//A heading of the theme. I need text + shortcode in title=""
[dt_fancy_title title="My name: [get_name]"]
//I tried this but it doesn´t work
[dt_fancy_title title="My name: "][get_name][/dt_fancy_title]
I use many headings or other widgets with different titles. The text is different in every title. | No, you can't do that, as the title argument is passed as a string.
Given the information you provided, I suppose that your `[dt_fancy_title]` shortcode does not actually execute shortcodes.
The syntax for this function should be:
function dt_fancy_title_callback( $params, $content = null ) {
// extract the title argument from the params, setting default value
extract( shortcode_atts( array(
'title' => 'default title'
), $params ) );
// execute your function, whatever it does
// call for shortcodes to be executed within your shortcode
$content = do_shortcode( $content );
// return the content
return $content;
}
add_shortcode( 'dt_fancy_title', 'dt_fancy_title_callback' );
If you do not call the `do_shortcode()` in your callback function, the shortcode texts inside will be interpreted as a string. | stackexchange-wordpress | {

Wordpress Plugins vs Traditional PHP membership website
I want to create membership website, as a form of passive income and also a way of improving my skills (I'm a UI/UX designer and front-end developer).
The problem is that in theory, I would like it to grow to an almost 6 figure income per year and I don't have experience making these type of "complex" websites. My main fear is the website security.
I'm good at Wordpress, well to some extent, but I can't write complex PHP websites with all those login and membership systems.
So, in terms of security, would it be better to use an already written Wordpress membership plugin (s2member for example) or take the time and learn how to build a more or less secure system in pure PHP myself? | Even if you're skilled in "complex PHP websites" it's safer to go with something that's already built. If you code it yourself you're very likely to overlook security issues and you'd have to constantly be updating it. It's worth investing a bit of money in plugins up front (if necessary; you may well do fine with free plugins, just do lots of research up front to see how well supported the plugins are, how many active installs, all that type of plugin vetting you should do in any case) so you don't have headaches down the road. And if you're expecting triple-digit income please be sure to find solid managed WP hosting, your own VPS or something similar, so that if things go south you have someone to help immediately. | stackexchange-wordpress | {

Can't delete the default jQuery in the theme
In my theme, jQuery is loaded in the header by default. I even dequed it in my `functions.php` but still in the header I have the jquery :

$scripts->remove( 'jquery');
$scripts->add( 'jquery', false, array( 'jquery-core' ), '1.2.1' );

function wpdocs_dequeue_script() {
wp_dequeue_script( 'jquery' );
}

but this is printed in the header:
<script type='text/javascript' src='...wp-includes/js/jquery/jquery.js?ver=1.12.4'></script>

How to Escape Custom Meta Data And Prefix Custom Meta ID
Here is a code snippet where I tried to retrieve a custom meta data from a custom post type.
$p_client_link = get_post_meta( $post->ID, 'client_link', true );
<a href="<?php echo esc_url( $p_client_link); ?>"><?php the_post_thumbnail( 'client_logo' ); ?></a>
My queries are:
1. Q. esc_url( $p_client_link); == right/wrong? esc_url() or esc_attr()?
2. Q. custom meta id client_link. Is it necessary to add prefix with this custom meta id like ‘p_client_link’?
3. Q. Is it right to use esc_url() for any ‘href’ attribute value?
N. B. I have been developing a one page WordPress theme for themeforest submission.
Thanks in advance. :) | 1. esc_url() - The correct option. He will prepare a string for use in attributes. Doc: <

add_rewrite_rule no longer working - possible https issue?
I have a redirect rule that is intended to load a custom template file. This worked last week, and is now not working (and loads a 404 page instead). The only change to the site is the entire site is now loaded on https instead of http.
Here is the function:
function event_rewrite() {
add_rewrite_rule('^event/(.*)/?', 'index.php?pagename=event&event_name=$matches[1]', 'top');
}
add_action('init', 'event_rewrite');
Is there anything in the matching that would change with https in the url? Or is there a different problem going on that coincidentally arose when we switched to https? | This _might_ be a permalink issue. Sometimes when things like HTTPS get turned on, you need to flush permalinks to get URL's and rewrites working again.
Head to permalinks (settings > permalinks) and just hit the save button and see if that fixes the issue there. | stackexchange-wordpress | {

Is it necessary to prefix every css class in a theme framework?
I'm working on a theme framework, prefix everything include css classes, so 'main-content' is 'framework-main-content', 'header' is 'framework-header', etc.
Recently I took a look at the famous framework Genesis, and I see no prefix for css classes at all, the HTML markup so that looks clean and also the CSS code.
It is no doubt we should prefix everything in PHP code, but is it necessary for css classes of a theme or theme framework? | Prefixes are used to avoid conflicts. If your framework is used to build a theme, the chances are high that there isn't a second theme framework in use at the same time. So there is no conflict, and therefore no need for a prefix.
The exception are CSS classes generated by the WordPress core, for example in the comment form. If you are using the same class names for an entirely different purpose, you need a prefix, or better class names for your use case. | stackexchange-wordpress | {

Widget outputting JS as plain text
I have made a custom widget that works in a shortcode but when i go to use it as a widget the javascript involved in the output is shown as plain text.
How do i make a widget output javascript as javascript not plain text? | Did you try to put propper `<script>`tags around your code?

Nav menu category links not showing
I am new to wordpress and have a project where I have show nav menu category links like this:
<?php wp_nav_menu(array('theme_location' => 'primary', 'menu_class' => 'menu right'));
After adding a new category in the admin, the new category link is not showing in the menu. What should I do about that? | A `wp_nav_menu` is a manually created menu - WordPress doesn't create it for you. If you want to keep using this function, you can go to either Appearance > Menus or Appearance > Customize > Menus, add links to the menu, and check the "primary" theme location under Display Location.
However - if you're just wanting to show category links, it's better to use one of the built-in options so that you don't have to manually add each category and keep them updated.
Option 1: create a sidebar and use the built-in "Categories" widget.
Option 2: pure code:
<?php
$args = array(
'orderby' => 'name',
'parent' => 0
);
$categories = get_categories( $args );

Switching Theme and back will reset the previous Theme's settings?
Everyone,
I have a Wordpress site on my hands, and I wanted to try a new Theme; I changed the active one and, unsatisfied, I selected again the previous one... and I found the website's appearance to be changed.
Is there a safe way to restore the site's appearance or are the settings lost and I need to recreate them? | Depending on the theme this could happen. It's not great coding, however I have seen that happen. Did you restore to the exact theme though or did you make changes (even a name change will cause reverting to defaults)?
**It may be as easy as once you go activate the original theme, go into it's settings page and click save.**
Some themes in their setup section will have a back up and restore option. If you previously backed up the settings you can restore them there.
If you don't have any of the theme backed up, you can always do an actual database restoration from before the switch and this will revert the changes back to their working state. | stackexchange-wordpress | {

Add custom attribute to menu item link using Filter

var currentitem = $( '.current_page_item > a' );
currentitem.attr( 'aria-current', 'page' );

// Select the li.current_page_item element
// Add `aria-current="page"` to child a element

I can't get blog posts into 'featured areas' on homepage

To configure them, you need to go into the admin, choose appearance, then customize.
In here, choose Theme Options, then Homepage (Featured) and this will open the section to edit the content of the three areas. | stackexchange-wordpress | {

Update my custom WordPress Plugin through my own server
I am working on a WordPress plugin that will be accessible only to a group of a few selected website owners. I have installed my plugin to those sites already. There is active development going on for this plugin. And we need to upload changes to all the sites. Manually uploading the changes in all sites will be a tedious process. So I would prefer to upload changes to all of those websites at the same time.
How is this possible with WordPress? | Yes you can. Check this Repo
<
This is a custom update checker library for WordPress plugins and themes. It lets you add automatic update notifications and one-click upgrades to your WP Plugin. All you need to do is put your plugin/theme details in a JSON file, place the file on your server, and pass the URL to the library. The library periodically checks the URL to see if there's a new version available and displays an update notification to the user if necessary.
You can either manage your update/source code on your own server or you can store them on BitBucket or Github
