Display content if i'm in the post - wordpress

I hope i will be clear with my explaination . Is it possible to show for exemple a simple text if the user is in the post .
For instance, i show in my case a simple text if the user is in the template category, but i want to display also this text if the user is in the content of the post :
I need with a function because it's in the header.php file .
With this function, i can show the simple text "Hello World" if i'm on http://mywebsite.com/category/ and what about http://mywebsite.com/the-name-of-the-post ?
<?php if (basename($template) == "category.php")
{
echo 'Hello World';
}
?>
Thanks guys, i hope it's clear (sorry for my english)

You should use WordPress Conditional Tags:
if ( is_single() || is_page() ) ) {
// If it's a single post or a single page echo 'Hello Single!'
echo 'Hello Single!';
}
if ( is_archive() && is_category() ) {
// If it's an archive page for any category, echo 'Hello Category!"
echo 'Hello Category!';
}
Read more about Conditional Tags on the WordPress Codex.

Wordpress custom button link output after the_content

I'm trying to insert a button to show at the end of each post on Wordpress in which the link it goes to is defined by a setup using the custom fields plugin. When creating each post, I am able to select the link I wish to display.
Here is the code I have which I know is wrong but I was hoping someone could help here.
function wpb_after_post_content($content){
if (is_single()) {
$content .= 'Contact Franchise →';
}
return $content;
}
add_filter( "the_content", "wpb_after_post_content" );
I assume $franchise_profile_url is a variable and you should concatenate it in the string like this
$content .= 'Contact Franchise →';
function afterContent($content) {
if(!is_feed() && !is_home()) {
$content.= "<div class='footNote'>";
$content.= "<h4>Click the below button if you like it:</h4>";
$content.= "<p><a href='#'>LIKE</a></p>";
$content.= "</div>";
}
return $content;
}
add_filter ('the_content', 'afterContent');
Use the above function. It will help you to achieve what you need.
Thanks for the help here, however, that code simply links back to the post itself and isn't pulling in the URL as set on the post using custom fields. This is the code I had set up before which was working on a default post setup but now I wish to use an alternative method in the functions.php file
<?php if( get_field('franchise_profile_url') ): ?>
Contact Franchise →
<?php endif; ?>

Removing URL from displaying in get_the_content

I'm building out my theme and running into an issue where YouTube URLs are showing up in what I'm using as the excerpt. I currently have a conditional that will show a trimmed down content IF there is no excerpt. Here is my template code:
<?php
if ( ! has_excerpt() ) {
echo wp_trim_words(wp_strip_all_tags( get_the_content(), 40 )) ;}
else {
the_excerpt();
}
?>
In this particular example, https://imgur.com/EdLdInW
the post has a YouTube Gutenberg block as it's first block and showing a trimmed and stripped the_content. It's pulling the YouTube URL which I don't want.
Currently on Wordpress 5.1.1 with Understrap framework. Any help would be great!
You can remove the URL by using preg_replace:
$string = "The Third Culture: The Frontline of Global Thinking http://someurl.com/;via #edge";
$regex = "#(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?)?)#";
echo preg_replace($regex, ' ', $string);
So in your case it will be like this:
<?php
if ( ! has_excerpt() ) {
$content = wp_trim_words(wp_strip_all_tags( get_the_content(), 40 )) ;
$regex = "#(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?)?)#";
echo preg_replace($regex, ' ', $content);
}else {
the_excerpt();
}
?>

Title (<title>) of wordpress site is not proper

In wordpress title of the page is divided by |. In my project On my front page title is fine (e.g. title | title). But in the inner pages title is not complete. Its not showing second part after | (symbol).
I have tried
<title><?php bloginfo('name'); ?> | <?php is_front_page() ? bloginfo('description') : wp_title(''); ?></title>
But it does not show anything after | symbol (in inner pages).
I have also tried wp_title(). But its start showing url in the title instead of name/title. What else I can try to make my title correct
Your code
Prints the name of your website
Prints a pipe (|)
a. If it's the home page, it prints the description of your website (“Tagline” set in Settings > General)
b. If not, it prints the title of the current page
If it's printing {blog_title} | {blank} it most likely means something is wrong with the Page title. In the WP Admin, ensure the Page you're viewing has a Title set.
Alternatively, an SEO plugin is conflicting with the title function - try disabling plugins one by one and see if it impacts the output.

Bloginfo, is_front_page, wp_title
From codex:
<?php
if ( ! function_exists( '_wp_render_title_tag' ) ) :
function theme_slug_render_title() {
?>
<title><?php wp_title( ' ', true, 'right' ); ?></title>
<?php
}
add_action( 'wp_head', 'theme_slug_render_title' );
endif;
?>
Since Version 4.1, themes should use add_theme_support() in the functions.php file in order to support title tag, like so:
I have fond a solution with the help of THIS POST
Just did little bit changes in the solution of that post and its working fine now.
<title><?php if (is_front_page()) { bloginfo('name');echo ' | ';bloginfo('description'); } elseif ( is_category() ) { single_cat_title(); echo ' - ' ; bloginfo('name'); }
elseif (is_single() ) { single_post_title(); }
elseif (is_page() ) { bloginfo('name'); echo ' | '; single_post_title(); }
else { wp_title('',true); } ?></title>

How to use If condition for wordpress plugin Widget Logic

I'm trying to put an IF condition on a widget through the plugin Widget Logic.
if single post is 'this', then dispay this text.
I tried this but it doesn't work, do you know why ?
if ( is_single( 'dialyse-mayotte' ) ) {
echo 'test'; // conditional content/code
}
thanks for your help
is_single only checks if the page is single you should check if the page is this and is it a single page
if ( is_page( 'dialyse-mayotte') && is_single() ) { echo "test"; }

How can I get the current page name in WordPress?

What PHP code can be used to retrieve the current page name in a WordPress theme?
All the solutions I have seen so far:
the_title()
get_page()->post_name
get_post()
etc.
But these don't work for a page that contains post entries. They will all return the name of the latest blog entry.
Stated another way, assume that you have a page created in WordPress with the name "My News". This page is set as the "post page". Add a couple of posts to the page.
Now, what API can be used to retrieve the string "my-news" instead of the name of the latest post?
I've found the following variable which seems to work.
$wp_query->queried_object->post_name
This is actually the URL friendly version of the page name (slug), which is what I was looking for too. This was tested with the default template (Twenty Ten). I'm really not sure why the two variables given below do not work on my site. Thanks to keatch for the print_r() tip.
Now, why is this information hidden so deep down?
The WordPress global variable $pagename should be available for you. I have just tried with the same setup you specified.
$pagename is defined in the file wp-includes/theme.php, inside the function get_page_template(), which is of course is called before your page theme files are parsed, so it is available at any point inside your templates for pages.
Although it doesn't appear to be documented, the $pagename var is only set if you use permalinks. I guess this is because if you don't use them, WordPress doesn't need the page slug, so it doesn't set it up.
$pagename is not set if you use the page as a static front page.
This is the code inside /wp-includes/theme.php, which uses the solution you pointed out when $pagename can't be set:
--
if ( !$pagename && $id > 0 ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = $wp_query->get_queried_object();
$pagename = $post->post_name;
}
My approach to get the slug name of the page:
$slug = basename(get_permalink());
<?php wp_title(''); ?>
This worked for me.
If I understand correctly, you want to get the page name on a page that has post entries.
Ok, you must grab the page title before the loop.
$page_title = $wp_query->post->post_title;
Check for the reference: http://codex.wordpress.org/Function_Reference/WP_Query#Properties.
Do a
print_r($wp_query)
before the loop to see all the values of the $wp_query object.
You can get the current page, post, or custom post type with the global variable $post:
echo $post->post_title
Note: In a function or class you'll need to specify global $post; prior to trying to use $post.
If you have loops on your page, make sure you end each loop with wp_reset_postdata(); to set $post back to the default item being displayed (the page).
Note, the 'post_title' variable is also available for any custom loop / query... including menu items and media attachments... everything in WordPress is a 'post'.
We just need to use the "post" global variable:
global $post;
echo $post->post_title;
This will echo the current page/post title.
If you're looking to access the current page from within your functions.php file (so, before the loop, before $post is populated, before $wp_query is initialized, etc...) you really have no choice but to access the server variables themselves and extract the requested page from the query string.
$page_slug = trim( $_SERVER["REQUEST_URI"] , '/' )
Note that this is a "dumb" solution. It doesn't know, for instance that the page with the slug 'coming-soon' is also p=6. And it assumes that your permalink settings are set to pagename (which they should be anyway!).
Still, can be a useful little trick if you have a controlled scenario. I'm using this in a situation where I wish to redirect non-logged in visitors to a "coming soon" page; but I have to make sure that I'm not throwing them into the dreaded "redirect loop", so I need to exclude the "coming soon" page from this rule:
global $pagenow;
if (
! is_admin() &&
'wp-login.php' != $pagenow &&
'coming-soon' != trim( $_SERVER["REQUEST_URI"] , '/' ) &&
! is_user_logged_in()
){
wp_safe_redirect( 'coming-soon' );
}
I believe that the Roots starter theme has a fantastic function to get the current page title. It is very hackable, covers all bases, and can be easily used with the wp_title hook.
/**
* Page titles
*/
function roots_title() {
if (is_home()) {
if (get_option('page_for_posts', true)) {
echo get_the_title(get_option('page_for_posts', true));
} else {
_e('Latest Posts', 'roots');
}
} elseif (is_archive()) {
$term = get_term_by('slug', get_query_var('term'), get_query_var('taxonomy'));
if ($term) {
echo $term->name;
} elseif (is_post_type_archive()) {
echo get_queried_object()->labels->name;
} elseif (is_day()) {
printf(__('Daily Archives: %s', 'roots'), get_the_date());
} elseif (is_month()) {
printf(__('Monthly Archives: %s', 'roots'), get_the_date('F Y'));
} elseif (is_year()) {
printf(__('Yearly Archives: %s', 'roots'), get_the_date('Y'));
} elseif (is_author()) {
$author = get_queried_object();
printf(__('Author Archives: %s', 'roots'), $author->display_name);
} else {
single_cat_title();
}
} elseif (is_search()) {
printf(__('Search Results for %s', 'roots'), get_search_query());
} elseif (is_404()) {
_e('Not Found', 'roots');
} else {
the_title();
}
}
Try this:
$pagename = get_query_var('pagename');
I have come up with a simpler solution.
Get the returned value of the page name from wp_title(). If empty, print homepage name, otherwise echo the wp_title() value.
<?php $title = wp_title('', false); ?>
Remember to remove the separation with the first argument and then set display to false to use as an input to the variable. Then just bung the code between your heading, etc. tags.
<?php if ( $title == "" ) : echo "Home"; else : echo $title; endif; ?>
It worked a treat for me and ensuring that the first is declared in the section where you wish to extract the $title, this can be tuned to return different variables.
Use:
$title = get_the_title($post);
$parent_title = get_the_title($post->post_parent);
echo $title;
echo $parent_title;
This seems to be the easiest to use:
<?php single_post_title(); ?>
One option, if you're looking for the actual queried page, rather than the page ID or slug is to intercept the query:
add_action('parse_request', 'show_query', 10, 1);
Within your function, you have access to the $wp object and you can get either the pagename or the post name with:
function show_query($wp){
if ( ! is_admin() ){ // heck we don't need the admin pages
echo $wp->query_vars['pagename'];
echo $wp->query_vars['name'];
}
}
If, on the other hand, you really need the post data, the first place to get it (and arguably in this context, the best) is:
add_action('wp', 'show_page_name', 10, 1);
function show_page_name($wp){
if ( ! is_admin() ){
global $post;
echo $post->ID, " : ", $post->post_name;
}
}
Finally, I realize this probably wasn't the OP's question, but if you're looking for the Admin page name, use the global $pagenow.
Within the WordPress Loop:
if ( have_posts() ) : while ( have_posts() ) : the_post();
/******************************************/
echo get_the_title();
/******************************************/
endwhile; endif;
This will show you the current page title.
For reference: get_the_title()
Here's my version:
$title = ucwords(str_replace('-', ' ', get_query_var('pagename')));
get_query_var('pagename') was just giving me the page slug. So the above replaces all the dashes, and makes the first letter of each word uppercase - so it can actually be used as a title.
Show the title before the loop starts:
$page_title = $wp_query->post->post_title;
This is what I ended up using, as of 2018:
<section id="top-<?=(is_front_page() ? 'home' : basename(get_permalink()));?>">
I've now found this function on WordPress Codec,
get queried
which is a wrapper for $wp_query->get_queried_object.
This post put me in the right direction, but it seems that it needs this update.
This also works if you are in the functions.php. It is not the best approach since you have to use the global array, but it works.
First, we need to add a filter. There must exist a better filter to use than the template_include, but I don't know all of them. Please point me to the right one.
add_filter( 'template_include', 'var_template_include', 1000 );
function var_template_include( $template ){
global $wp_query;
$GLOBALS['current_page'] = $wp_query->get_queried_object()->post_name;
return $template;
}
Avoid using the variable directly
function get_current_page( $echo = false ) {
if( !isset( $GLOBALS['current_page'] ) )
return false;
return $GLOBALS['current_page'];
}
Now you can use the function get_current_page() in any other part of the functions.php.
