Category name as page title
I'm using a theme from Envato Market (Painting). What I need to do is to replace a generic page title which is displayed when I open a category page from Shop or Portfolio, with the actual name of the category. The developer of the theme said that I can’t dynamically display the title. But in the same time I see that the breadcrumbs shows the correct title of the category. Could the page title be grabbed from the breadcrumbs and displayed? Or maybe there is another solution. Can someone help me and explain it for a noob? Thank you! | You can change the code in the theme files to do this. Open the file `category.php` (if this file doesn't exist, try `archive.php`) and replace the text you want to change with `single_cat_title()`
Here is the documentation
**However these changes will be overwritten if you update your theme**
You can create a child theme or use plugins to get around this. | stackexchange-wordpress | {

wordpress.com website url structure
Should I able to change URL structure of WordPress blog? (Free WordPress hosted blog)
Right now I have this way: (see URL structure)
helloworld.wordpress.com/london
But I want to use as this way:
helloworld.wordpress.com/carhire/uk/london
Is this achievable? | Yes, this is achievable and quite simple to do so. Go to **Settings** > **Permalinks** in your admin area.
There you should be able to select **Custom** and use a value like (if you want all URLs to start with /carhire/uk/)
/carhire/uk/%postname%/
If your logic is more complex, I suggest using a plugin such as Custom Permalinks.
**Edit:**
I just tried it myself, on the wordpress.com free plan it seems that you can't change permalinks at all (neither via settings nor via plugin). If you upgrade to the Business plan (~24$/mo), it is possible to install plugins - and the aforementioned should solve this. | stackexchange-wordpress | {

CSS in child theme isn't working properly
I am trying to get a child theme to work. At first it didn't load because it didn't recognise it as a child theme. Now it does work but when I activate it, it loads a version of my page seemingly without any css or something. There's only text and images there, but no styling.

wp_enqueue_style( 'child-style',

array( $parent_style ),
wp_get_theme()->get('Version')
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
?> | You'll have to enter that code at the start of the functions.php file in your child theme to include the parent theme's `style.css` file

How to hide few theme customization options - TwentySeventeen theme
I am just trying to modify Twenty Seventeen theme by and I want to hide few customize options like **Header Media** and **Colors** how can I do it ?

I have researched it but it seems like the given options are unable to hide these menus.
Can someone give me a hook or something to be able to hide this please.
Thanks | You can change `active` status of section using `customize_section_active` `filter`. It gives 2 parameters `$active`-`bool` and `$section`-`object`. Haven't tried it so you can try and see if works for you.

Update WP option by plugin
I wanted to set value of **WP option** (more specifically - 'admin_email') by using plugin, **its option** (plugin option) and update_option().
I tried using lines like below, but when plugin code contains them - it gets disabled. Any ideas why?
$helper = (get_option('plugin-option');
update_option('admin_email', $helper );
**EDIT**
$helper = get_option('plugin-option');
update_option('admin_email', $helper );
Now it's not disabling (due to bracket), but it still doesn't change option value | That option is special in that WordPress has code to intercept your call for security reasons:
<
> This function intercepts changes to the administrator's email address. It keeps the address from being updated and instead sends the user a confirmation email, with a link to confirm the change.
What you're trying to do could be easily abused, and any change of the administrators email should trigger notices as a basic security measure.

Hardcoded paths in my plugin
Sorry for the stupid question: I'm trying to create a basic plugin and from its main file I want to refer files in two directories that are in the same directory as the main plugin.

but it crearly creates a path that doesn't work for me.

What is this mark for "? function()"
I was working through someone else's code trying to understand their plugin so I could combine it with another plugin to do something different. I have no clue why this question mark is here in the middle of this entry. The code appears as such in one line:
`$variable = !empty( $_POST['variable_b'] ) ? explode( "\n", trim( $_POST['variable_b'] ) ) : array();`
I understand what the empty, explode, and trim functions do here. I assume that is all being amended to the array. The question mark almost seems like a mini conditional statement. | That's called Ternary Operator.
if( ! empty( $_POST['variable_b'] ) {
$variable = explode( "\n", trim( $_POST['variable_b'] );

How can I get users email (and additional data) from the rest API?
How can I get the email adress from the users by using the REST API? I'm authenticating with nonce, and it seems to be working since I can do POST requests and change stuff. Do I have to add something to make it return all the user info?
This is my JS:
(function($) {
var nonce = WPsettings.nonce;
var rest_url = WPsettings.rest_url;
$.ajax( {
url: rest_url + 'users/',
dataType: "json",
beforeSend: function ( xhr ) {
xhr.setRequestHeader( 'X-WP-Nonce', nonce );
}
} )
.done( function ( response ) {
console.log( response );
} );
})(jQuery); | To add the user's email address in the REST API response, register an additional field to the `user` object and add the email address:
register_rest_field(
'user',
'user_email',
[
'get_callback' => static function (array $user): string {
return get_userdata($user['id'])->user_email;
},
]
);
Please note, however, that this is _strongly_ discouraged because anyone can then see the email addresses if the code is running on a publicly accessible website. | stackexchange-wordpress | {

Reduce nonce lifespan
for a personal plugin (nothing going to the public or commercial), I built an AJAX form and its endpoint is a custom endpoint (REST Api).
When a certain Page containing my form is accessed, I generate a nonce.
Then, the user sends the form, I add the conventional header (`X-WP-Nonce`) and in the endpoint function I validate the nonce I first created when the page was loaded.
I would like my nonce to be short-lived, that is, 12 hours is too much.
I found I can use `apply_filters('nonce_life', timeHere)` but I don't know where this line is supposed to be: should it go right before this one?
$nonce = wp_create_nonce('wp_rest');
Moreover: could this line change the lifespan of ANY nonce in my WP or does the change affect only my nonce? I wouldn't want to break other plugins.
Thanks! | Yes, using that filter will affect the lifespan of all nonces created after this filter is added, and while it remains in-place. So your best bet is to add it, create the nonce, remove it:
function my_nonce_lifetime() {
return 600; // 10 minutes
}
add_filter( 'nonce_life', 'my_nonce_lifetime' );
$nonce = wp_create_nonce( 'wp_rest' );
remove_filter( 'nonce_life', 'my_nonce_lifetime' );
EDIT: As suggested by someone in the comments, you'll need to use the same filter later on when you're verifying the nonce, as below:
add_filter( 'nonce_life', 'my_nonce_lifetime' );
wp_verify_nonce( $your_nonce_value, 'wp_rest' );

Configuring WP-CLI on Windows 10
I've installed `php5-cli` using bash, but Wordpress is using XAMPP's PHP 7 install. I've added `/mnt/c/xampp/php` to the PATH, and I've explicitly used `export WP_CLI_PHP='/mnt/c/xampp/php'` in `.bashrc`.
But when I do `wp --info`, I get:
PHP binary: /mnt/c/xampp/php/php.exe
PHP version: 5.5.9-1ubuntu4.22
php.ini used: /etc/php5/cli/php.ini
`PHP binary` seems correct, but the last two variables refer to PHP 5. | Actually, I figured out how to do this, and it's actually really easy to do! Which is awesome because I think it's a great simple way to work!
First up, you don't want to change the PATH for PHP in bash. So you'll want to remove that. Instead, what you are doing is using bash based PHP and MySQL, but connecting to your Windows MySQL (installed by XAMPP).
**Step 1:**
`sudo apt install mysql-client php-cli php-mysql`
**Step 2:**
Create a symlink in bash to your website files, so something like this: `sudo ln -s /mnt/c/websites /var/www`
**Step 3:**
You need to connect to you MySQL db with an IP address, not localhost. So when creating your config do something like this:
`wp config create --dbname=wpdbname --dbuser=wpdbuser --dbpass=securepswd --dbhost=127.0.0.1`

I lost the link to my posts in my menu bar
I lost the link to my posts. Originally, when I went to "all pages" one would show up as "posts." Therefore it would show up in the menu bar.

However, if you click on any other page on the site, there is no way - in the menu bar- to get back to the posts. I would like a drop down menu of the posts to be there.

Adding a third custom taxonomies

In the functions.php I have added this code to give each page a second category.

register_taxonomy('players_team', 'player', array(
'hierarchical' => true,

Cannot get grandparent object

> $grandparent
>
> $greatGrandparent:

To get the parent and Grandparent objects, you need to get_post them also. The property "post_parent" only gives you the ID of that post, not the post_object itself.
So you change your code like this:
<?php
$current = get_post($post->ID);
//Conditional to be sure there is a parent
if($current->post_parent){
$grandparent = get_post($current->post_parent);
//conditional to be sure there is a greatgrandparent
if($grandparent->post_parent){
$greatGrandparent = get_post($grandparent->post_parent);
}
}
?>
<h2>$current: <?php echo $current->ID; ?></h2>
<?php if($grandparent){ ?>
<h2>$grandparent: <?php echo $grandparent->ID; ?></h2>
<?php if($greatGrandparent){ ?>
<h2>$greatGrandparent: <?php echo $greatGrandparent->ID; ?></h2>

Display published time for today's posts only
I'm building a blog theme. I know that `the_date()` and `date()` functions display published date of posts. And I know how to get posts' published time with `the_time()` function.
I want today's posts to show published **time** and all other old posts to show published **date**. For example, today is September 8. All the posts that were published today should show published time ( **08:40** , **16:30** , etc). But the posts that were published yesterday or longer before should show only date (September 07, July 26, etc).
How can I achieve this goal?
I guess there's a way to compare post's published date with today's date and make decision whether to display time or date that way. But there must be more optimal and easier way. | $post_date = get_the_date('d/m/Y');
$today = date('d/m/Y');

simple wordpress form redirection

<select>
<option value="test" >test</option>
</select>
<input type="submit" value="search">
</form>
the problem is, every time i click the search button, i get redirected to the homepage! Shouldn't this small little form be redirected to the page containing the form, since action is empty? | Alright guys, believe it or not, but the underlying problem had to do with permissions on the root folder!

Necessary css classes to be included in theme stylesheet
Developing a WordPress theme. I've got two questions
1. Does the first response here hold true even after 5 years?
2. Is it necessary / considered a good practice to include all the default html tags, for example `h1,h2,h3,h4,h5,h6,blockquote,acronym,abbr,code,pre,address` etc in my theme css file?
P.S: My aim is to publish the theme in wordpress.org. Even if they did allow me to publish it without the extra styling, I would like to know if it is a good practice to include it in any theme. | 1. So far, this is the most comprehensive list of all styling that theme might need for styling default widgets and other elements: Default WP CSS classes for a theme. You don't need to style all of them, but it is a good idea to use Theme Checker plugin to scan your theme before submitting it to WordPress.org, because it should pick up all the things that you might be missing, including in CSS.
2. Your theme should have good typography, and that requires you define styling for all typography elements, like headings (h1...6), paragraph (p), blockquote, pre... If you don't do that, browsers fall to default styling for those elements, and your theme might look different in different browsers.
My suggestion is to start with some boilerplate stylesheet like Normalize.css or some CSS/JS/HTML framework (like Foundation, but that might be an overkill, depending on your theme). | stackexchange-wordpress | {

Get rating product by product id
How to get product rating by product_id without loop?

How to return a string that has a variable inside in a shortcode?
$output = '<p class="one"><small>'.$newsletter_one. '</small></p>'
Generally, when we write short codes we publish HTML like the above one, and instead of echo use return function.
How should we write this one →
<span class="class2" id="class3-<?php echo $random;?>"> </span>
Like this →
$output = '<span class="class2" id="class3-.$random."> </span>'
or does this has some flaws? | When you want to return a data combined with a string, you can use one of the following methods:
Either open and close the string using `'`:
return '<span class="class2" id="class3-' . $random . '"> </span>';
Or use the double quote:
return "<span class='class2' id='class3-{$random}'> </span>";
You can simply use `$random` without the `{}` curly brackets, but it's easier to read if you use `{}`.
You can even use double quotes for the inner string, but you need to escape them:
return "<span class=\"class2\" id=\"class3-{$random}\"> </span>";
As pointed out in comments by @birgire, to make it more WordPressy, we can also escape the variable:
return sprintf( '<span class="class2" id="class3-%s"></span>', esc_attr( $random ) ); | stackexchange-wordpress | {

Remove Number Of Pagination
When I visit to my category page (example page 6) then my pagination is like this ->
[Prev][1][…][5][6][7][…][12][Next]

'mid_size' => 2,
'prev_text' => __( 'Prev', 'textdomain' ),
'next_text' => __( 'Next', 'textdomain' ),
) ); ?>

Using main style.css with add_editor_style
All the resources I've read online suggest using a different CSS file (i.e. `editor-style.css`) in order to style the WYSIWYG editor to better resemble what the actual content will look like.
For the purpose of testing I tried to just use the main `style.css` file that I've been using for the rest of the site and the styling in the WYSIWYG editor looks great and so far I haven't noticed any problems by doing this.
Should I still create a new `editor-style.css` and use that or is it an acceptable practice to use my main `style.css`?
For reference, this is the code I used below:
function wysiwyg_styles() {
add_editor_style( 'style.css' );
}
add_action( 'init', 'wysiwyg_styles' ); | The simplest answer is: you can use whatever stylesheet you want for the editor. `editor-style.css` is just the default stylesheet loaded if none is passed to `add_editor_style()`.
This will load the specified stylesheet:
add_editor_style( 'some-stylsheet.css' );
This will load editor-style.css:
add_editor_style();
Use whatever better fits your needs.
By the way, it is better practice to add the editor stylesheet using `after_setup_theme` action, not `init`, as it is something specific for the theme:
add_action( 'after_setup_theme', 'cyb_theme_setup' );
fucntion cyb_theme_setup() {

pre_get_posts shows posts in random order sometimes

$query->set('posts_per_page', 30);
$query->set('orderby', 'menu_order');
}
return $query;
}
add_filter('pre_get_posts', 'modify_query_amount_shown');
However, when I refresh my page several times, I notice the order of my posts changes each time. I can confirm that it has something to do with this code, because as soon as I comment it out, it returns to normal. | `pre_get_posts` is not a filter hook, it is an action. Also you should not set `orderby` to `menu_order` for posts as they are not hierarchical. Set `orderby` to `date` instead.
function modify_query_amount_shown( $query ) {
if ( $query->is_category ) {
$query->set( 'posts_per_page', 30 );
$query->set( 'orderby', 'date' );

How to calculate post index when using offset in custom query

Say I have a custom post type called colors with say 40 posts that are in the default order in single_colors.php I have:

2 Red 3 Blue 4 Green 5 Black 6 Yellow

add_action( 'publish_task', 'wpse_admin_email', 10, 2 );
function wpse_admin_email( $post_id, $post ) {
// prepare and send email code goes here...
}
If you want to send an email **on first publish only** , use the code below:
add_action( 'transition_post_status', 'wpse_admin_email_once', 10, 3 );
function wpse_admin_email_once( $new, $old, $post ) {
if ( $post->post_type == 'task' && $new == 'publish' && $old == 'auto-draft' ) {

Apply a filter only once
I want to remove automatically the _Home_ menu item, **but only once** , more precisely **at the first run of Wordpress or at the first child theme activation/loading**.

}
add_filter( 'wp_nav_menu_objects', 'filter_wp_nav_menu_objects', 10, 2 ); | There is no native WordPress hook called `add_filter_once()`. This is an custom solution which will help you to run your hook only once.
For example if inside a loop or whatever situation you are facing. However, The basic idea is to check when you need to stop using your hook and simply **remove_hook** from WordPress and once all done, you need to registere it again.
example code:
function add_filter_once( $hook, $callback, $priority = 10, $args = 1 ) {
$singular = function () use ( $hook, $callback, $priority, $args, &$singular ) {

How to add custom text near category/tag title in Wordpress Twenty Fifteen Theme?
You can see the archive.php's title php code on twenty fifteen theme here:
<?php
the_archive_title( '<h1 class="page-title">', '</h1>' );
the_archive_description( '<div class="taxonomy-description">', '</div>' );
?>
I would like to add some custom text after category/tag title. Can I do that with archive.php? How to do that? In twenty fifteen theme both category and tag pages use archive.php. | Before anything, you should create a child theme, so you can update the parent (Twenty Fifteen) without worries.
Looking at the WordPress hierarchy, you could copy the archive.php to the child theme and edit it, but would need to check what archive it is, of posts, custom post types, etc.
Instead, copy archive.php twice, rename one to category.php and one to tag.php. You could even use category-{slug}.php for specific categories (same goes for tags).
// in category.php / tag.php / ...
the_archive_title( '<h1 class="page-title">', '</h1>' );
_e('Some custom text','twentyfifteen-child');

looking for a hosting company for wordpress
I've never purchased hosting space from any company before. I have looked around and I saw that some of these companies claim that they specialise in wordpress hostings. Initially I thought I'd just purchase a normal hosting page, maybe their most basic package as I won't be expecting many visitors. Maybe under 10k visits per month with at least 10GB of space.
Also, what's the difference between a normal hosting space vs a specialised one for wordpress. If I'm using wordpress as a CMS, must I absolutely choose a specialised wordpress host?
Currenty, my wordpress website is being developed on my localhost and nearly done. How would I go about transfering that website to the hosting space? | WordPress is extremely lenient to the hosting requirements. It is likely one of the most forgiving CMSes to run on the least capable PHP hosts.
That said there _are_ advantages to _some_ of hosts that specialize in WP. Those that _do_ specialize and not just slap it on as marketing gimmick.
I would put advantages in roughly two categories:
1. Expertise. Specialized hosts have better awareness of WP as a solution, what it takes to run it smoothly, and keep it secure.
2. Tooling. Specialized hosts can offer server configuration and features specifically fine–tuned for WordPress, such as object cache backend or reverse proxy.
So while specialized hosts is completely unnecessary, there are some concrete benefits that make sense if budget works out for it.
Personally I highly value reverse proxy feature, since it removes the need for flaky static page cache plugins. | stackexchange-wordpress | {

How can I make an image full width inside a paragraph which is 70% (text)

Flush rewrite rules when new cpt is registred

I understand theres a `registered_post_type()` hook, but it seems to fire every time the admin is reloaded, making it a rather resource consuming operation.
Is there a hook that only fires when a **_new_** post type is registered? | Post types are registered on every load. They're not stored in the database or some other sort of persistent storage. The posts are, but not the post types.
So the correct place to flush rewrite rules is when the theme is activated. This can be done with the `after_switch_theme` hook:
add_action( 'after_switch_theme', 'flush_rewrite_rules' );
For a plugin, you'd do it with the activation and deactivation hooks:

Is it safe to add a new field to meta_value field?
I'm trying to offload Wordpress images from my web server. I've successfully moved everything over to `Amazon AWS` and have a syncing mechanism in place that uploads new images to AWS. Now I would like to store a flag somewhere that indicates whether the image has been synced so my custom theme can pick the correct path. I was thinking adding that flag to the `wp_postmeta` table, as part of the `meta_value` serialized object.
Is that a safe technique? What are the chances this value gets overwritten and lost?
Additionally, I assume the `guid` field `wp_posts` shouldn't be updated with the full path to the image on AWS? That could be a solution as well. | `guid` doesn't affect the image URL, it is just used as a unique identifier. It could be random gobbledygook and as long as it is unique it wouldn't make a difference. It should be safe to use postmeta as long as you aren't using any plugins that would potentially completely overwrite all postmeta associated with an attachment - no plugins I am familiar with would do so, just mentioning what you would need to check on. Most plugins use `update_post_meta` which adds or updates if a particular postmeta key is found, so use a unique `meta_key` and you should be safe. | stackexchange-wordpress | {

Sort WooCommerce data with WP-CRON?
I am building an e-commerce site with limited edition products.
Each Woocommerce product page has a custom attribute when the product will no longer be available to purchase.
When the product sale period completes, the 'add to cart button' is removed. If the original seller views their dashboard page, I can display a notification that their campaign has ended.
However, an admin needs to visualize the products that have been completed and their sale statistics. I can't rely on a function to send this data if it only runs when the original seller logs in.
**Logically, do I run a daily WP-CRON job that queries all products, compares the current time to their completion date, and conditionally manipulate data if the conditions are true?**
Is this bad practice, super slow, or is there a better approach?
_Slowly learning, thank you in advance for any guidance._ | This doesn't sound like a bad approach to me. The thing to keep in mind about `WP_CRON` is that it's not a "real" cron and is only triggered when someone visits the site.

add_filter img_caption_shortcode not implemented

$content = 'new caption' ; // change it
return $content; }

I have verified that the caption code is enabled with this code:
if ( shortcode_exists("caption")) { die("found caption shortcode"); }
And the generated page dies as expected.
Have carefully checked my caption_fix function to ensure that is returning content (if empty return $content, normal caption shortcode function is done).
This is with WP 4.8.1 and PHP > 5.3. (Added: WP 4.8.2 does same thing.)
Ideas? | (gotta read the docs a bit more carefully)
I was using this code in the loop
$xcontent =get_the_content();

$xcontent =get_the_content();
$xcontent = apply_filters('the_content', $xcontent);
So the issue was that filters were not being applied, since I used `get_the_content()` instead of `the_content()` .

It would be safest to use a plugin to migrate the users. It does appear that you'll have to have your old users reset their passwords, but that's a smaller price to pay than getting customers, authors, etc. all confused.

How do I escape a table name or column name in SQL? esc_sql doesn't do this
If you want to escape string values in an SQL query, you can use WordPress's `esc_sql` function:

<?php
$wpdb>-get_var(
$wpdb->prepare(
"SELECT * FROM something WHERE foo = %s",
$foo
)
);

How to store in the database directly the translation?

'guid' => null
);
wp_insert_post( $a_custom_post, true);

wp_redirect() does not work in custom template file

//
// wp_redirect() does not validate that the $location is a reference to the current host

// So use it only when navigating to another website

}
?> | Redirects are performed by outputting HTTP headers, `wp_redirect()` just adds some bits on top of it for flexibility.
Headers are only ever meant to be used _before any and all output_ to a page, since that is how HTTP response is structured.
Hypothetically it could work in template _if_ you make sure it fires before any output. Practically it is a normal practice to deal with redirects on an appropriate hook, before any template/output is ever reached. The common hook to use is `template_redirect`. | stackexchange-wordpress | {

Restrict custom fields based on user roles
I have search far and wide for this and the only solution i can find it restricting the amount of posts users can make.
We have a WP site that we would like to monetize with a simple directory of sorts for a very niche market. We would like to have various levels of advertising partners that have access to certain fields dependent on their level.
Example Gold would have 10 images, Bronze might have 1. Or gold has the "website" field.
I am using ACF heavily over the site, and i do not need payment plugins or a front-end solution, we can work out the payment side separately and we will be using the Wordpress backend. I just need to be able to modify field availability based on a users role. Is there any way to achieve this?

Testing localhost WordPress site over LAN with iPad, iPhone

changing localhost to 192.168.0.16 inside the site and Wordpress address. Can anyone advise me on what I'm doing wrong?

Find and Replace text in the entire table using a MySQL query
Website has been hacked and they have injected javascript into every single post, page and product (woocommerce) - Editing every page manually would take for ever, we have over 3000 posts.

$ wp search-replace '<script>bad javascript code</script>' '' --precise
By default, this only searches for tables registered in `$wpdb`. To overwrite this behaviour, you can use either the `--all-tables` or `--all-tables-with-prefix` flag. (Or pass table names to the command manually.)
**Alternative** : Easiest would be to download a dump, search/replace in that file and finally import again.

Overriding post's font-family
I have several users posting on my page. Some of them like to prepare post in Word and then copy-paste it into the WordPress Editor. Word uses custom inline CSS anc I'd like to get rid of the part which is changing the font family.
Is it possible to replace/remove font-family css from all the posts already posted (I don't want to use some filter when outputting post to the page or using some CSS combined with !important). Solutions like "don't use Word" or "tell them to stop changing the font" won't help. Thanks. | You could run a regex. Since they're continuing this behavior, you will probably want to create a custom plugin and set up a cron job to trigger it periodically so it will continue stripping all inline styles.
Your plugin will need to query all posts. From there, in a loop that checks each post's content, use
`preg_replace('style="*.*?"', '', $content);`
which will replace each inline style with nothing (''), essentially deleting it. | stackexchange-wordpress | {

How to display to visitor which site they came from?
kind of new to this so not sure how to go about this. The task given to me is to that when a visitor arrives at the site through a link, I need to display to them where they came from.
So if they used Google and clicked on a link in Google to load my site, the site would say something like "Welcome visitor from www.google.com."
First, how to get the information where they came from, I don't really know. I was originally considering using the WP Statistics plugin, but then I was told that the HTTP header would contain this information. I don't really know what the HTTP header is or how it works or if there are exceptions.
What would I use to figure out the referreer, and how can I display that to the user? This site is self-hosted so I have access to all the files via my hosting provider's cPanel.
I am using the "Basic" WordPress theme. Thanks. | WordPress has a function that can extract referrer information (website where user originated from): `wp_get_referer()`.
It will return URL from the originating website. If that is not available it will return `FALSE`.
This is the simple example PHP function that will display welcome message when called, if the referrer is set:
function wse_280729_show_welcome_message() {
$ref = wp_get_referer();
if ($ref) {
echo "Welcome visitor from '$ref'.";
}
}
How will you use this is up to you, and depends where you want to display this, and will involve some theme modification and calling this function to show the message (if referrer is set). | stackexchange-wordpress | {
