I've got kind of a unique scenario that I'm trying to nail down. I'm working on a new template for a custom post type that already exists. Basically, we're replacing the single-customposttype.php file with a new one. All of that is going swimmingly, except one thing - they have one post in that custom post type that they want to keep the OLD template on.
So there's a NEW single-customposttype.php file that will work as the default single template for that CPT.
But I need ID #93 to use the OLD single-customposttype.php template. I hoped just doing single-customposttype-93.php might do the trick, but it doesn't. What's the best way to apply the other template to only one post id?
Thanks in advance!
I deal with custom template loading all the time, it's really pretty simple! Really, all you need to do is hook into the template_include hook, and override the template based on whatever conditions you want.
That hook takes a single argument, the $template file to load. You can then use any conditionals you want and force a separate file to load instead.
add_filter( 'template_include', 'custom_template_include', 99 );
function custom_template_include( $template ){
// For ID 93, load in file by using it's PATH (not URL)
if( get_the_ID() === 93 ){
// Note the file name can be ANYTHING, the WP auto-template names don't matter here
$file = get_stylesheet_directory() . '/post-id-93-custom-template.php';
// It's generally good to see if the file exists before overriding the default
if( file_exists( $file ) )
$template = $file;
}
// ALWAYS return the $template, or *everything* will be blank.
return $template;
}
It's really that simple! Inside the custom PHP file, you have access to all of the WordPress functions and such as you would with a default template.
Generally you'll want to use the file_exists() function on the template, just to make sure it's found, otherwise you'll be passing along a file that doesn't exist, and that page will not load. By checking if it exists, it will still fall back to the old template if it's not found (deleted/renamed/moved, etc)
Also, you always need to have return $template at the end, otherwise anything that uses WordPress' template system will break.
I made a quick example on a demo site:
https://xhynk.com/content-mask/policies/cookie-policy/
https://xhynk.com/content-mask/policies/use-another-template/
The policies are a custom post type, and the cookie policy loads normally. The other one is modified with the same code as above (with the name/ID changed to match), and it's loading in a simple .php file with that content in it.

I am trying to create custom plugin in wordpress.
We want to create a case like if user is not logged in to the system then user should be redirected login page. I tried wp_redirect and wp_safe_redirect but it is not working. here is my code.
if (isset($_SESSION['game_login'])) {
//Do Something
}else{
wp_redirect('login');
exit():
}
I am getting this warning
Cannot modify header information - headers already sent by (output started at wp-includes/class.wp-styles.php:225) in wp-includes/pluggable.php on line 1216
can someone suggest me in this scenario?
You shouldn't just start output buffers wherever unless you're specifically delaying the final output, such as modifying content on the template_redirect, using add_shortcode, or any numerous scenarios where you intend to buffer the output.
The code in your example should be encapsulated in a function and hooked to one of WordPress' many Action Hooks. Typically this kind of function is added on the plugins_loaded or init hooks.
add_action( 'init', 'redirect_anonymous_users' );
function redirect_anonymous_users(){
if( isset( $_SESSION['game_login'] ) ){
// Do Something
} else {
wp_redirect('login');
exit();
}
}
There may be several reasons causing this issue.
Try this points and hope this may have a fix
Remove blank space from files that are showing error after php ?> tag at end of file, But in your case
it is from core file, So don't modify anything in terms of code just try to remove blank space at the
ending of those files. Also remove blank space from bottom of files
wp-config.php and functions.php
If the above point does not work add this code to your wp-config.php file
ob_start();
error_reporting(0);
In my plugin i have created a custom template that prints a requested sidebar. and for running the code of this template i assigned a custom page to it (by calling update_metadata) .
Is it a good idea for getting content of a specific sidebar into Ajax call ?
Now my problem is that WORDPRESS shows it in the dashboard and front page , and after searching i have not found any easy to understand solution for Hiding a page completely so only can be accessed by its id .
Can any one tell me how to do that ?
you are going about this the wrong way. You can create a function that can create anything that can be created on a wordpress page.
But if you really must you can create a page outside of the database, etc:
add_action('init', 'add_rewrite_rule');
function add_rewrite_rule(){
// add_rewrite_rule(REGEX url, location, priority (i.e. top is before other rewrite rules)
// I created a custom post type for this plugin called market -- replace post_type with whatever you want
//basically tell wordress to add a query var if sidebar is added to url.
add_rewrite_rule('^sidebar?','index.php?is_sidebar_page=1&post_type=market','top');
}
// register a query var
add_action('query_vars','market_set_query_var');
function market_set_query_var($vars) {
array_push($vars, 'is_sidebar_page');
return $vars;
}
// associate a template with your quer_var
add_filter('template_include', 'market_include_template', 1000, 1);
function market_include_template($template){
if(get_query_var('is_sidebar_page')){
$new_template = (theme or plugin path).'/pages/yourpage.php'; // change this path to your file
if(file_exists($new_template))
$template = $new_template;
}
return $template;
}
This will not be a page that will be in the admin section or in any query that relates to pages but someone could of course navigate to this page. But as i said above you would be better to create a function to create your sidebar. If you want a seperate file to handle the "view" you use require_once 'filename'; a file and keep your functions area free of html.
If you are creating functions in a wordpress plugin dont forget many functions may not be available until later in the load process. Use add_action() if you run into any undefined functions
edit:
you are loading wordpress before you get to the template so you have all the functions. (google wp load for more info) + get_header() / get_footer() will also load a few things like css, etc. I had a small typo in the code above, fixed that but basically what you are doing is telling wordpress if someone lands on www.example.com/sidebar to apply a query_var (rewrite rule). Wordpress will look up its saved vars (final function) and return the template assoc. The 2nd function just registers the var.
You also have wp_functions in any file you create and include in a plugin, etc hence why you can create a file that does exactly the same as this page.
I am writing a Wordpress plug-in that creates several Custom Post Types (CPT). For they have their own custom fields, that need to be displayed in the search results, I need to customize the search results output.
Do I need to write my own theme for that or is there a hook (or other way) to solve this in my plug-in code?
You could hook into get_the_content and get_the_excerpt filters and test with is_search() to see if you should alter the returned value or not.
Not tested, but this is the idea:
add_filter( 'get_the_excerpt', 'my_search_excerpt' );
add_filter( 'get_the_content', 'my_search_excerpt' );
function my_search_excerpt( $content ) {
if ( is_search() ) {
$content = 'This is a search excerpt for ' . get_the_title();
// maybe add a read more link
// also, you can use global $post to access the current search result
}
return $content;
}
I see four possibilities:
Create a new (child) theme
Override the search template using filters (template_include)
Use client-side code to modify the appearance (CSS / JavaScript, poor workaround)
Hook the_content or the_excerpt
The easiest way might be to copy the search.php file of your installed theme and modify it to fulfill your needs. You can then hook it in using the first or second way. The first requires you to create a child theme, the second to create a plugin. The latter might be more complex so I would suggest to create a theme (take a look at template files of child themes for an explanation).
is it possible to make a custom page for buddypress with its url like this: http://domain.com/custom_page ? I found some answers by searching google but it does not create a custom page. i have a code here that i found in one of the blogs.
define('BP_FUN_SLUG','fun');
function bp_show_fun_page() {
global $bp, $current_blog;
if ( $bp->current_component == BP_FUN_SLUG && $bp->current_action == '' ) {
// The first variable here must match the name of your template file below
bp_core_load_template( 'fun', true );
}
}
add_action( 'wp', 'bp_show_fun_page', 2 );
but this code does not work... Is anyone there knows how to do this? thanks
Yes, it is possible to create a new page in Buddypress.
In Buddypress you have to create a new plugin or create a function in the theme functions file.
For creating first you have to add a new page link in navigation menu using bp_core_new_nav_item() function (You have created sub menu for that use bp_core_new_subnav_item() function).
Above two functions pass the screen function name as a parameter this name use when you click the custom page link call to this screen function. Create new function in your functions.php file same as screen function name. In this function call to your custom template file using bp_core_load_template() function.
Then finish, add more logic to create a new function and call it in the template file.
Another approach is to add a plugin that allows php in posts. For example http://wordpress.org/extend/plugins/allow-php-in-posts-and-pages/
Then create a page and add this to it:
[php] locate_template( array( 'some-template-folder/something.php' ), true ); [/php]
In case someone is wondering how to integrate custom pages into user profile (so that it looks like activity stream, groups etc.).
One thing i did recently was define a plugin (functions.php would work as well), register a custom slug with bp_core_new_nav_item or bp_core_nav_subnav_item and loaded member/single/plugins.php template in the handlers for those slugs. There are a bunch of actions on that page that you can hook into like bp_template_title and bp_template_content.
This can give you a whole lot of control.
Here's a link to the source of plugins.php: http://phpxref.ftwr.co.uk/buddypress/nav.html?readme.txt.source.html
I'm making a plugin where I want the comments in a single post page not to be printed at all. I need to query the database myself and print my own html with the results.
How can I make WordPress to not print the comments, without disabling them?
Thank you
EDIT:
as a suggestion, I am using:
apply_filters('comments_template', array($this,'comments_template'), 10, 1);
function comments_template($template){
$template = '';
return $template;
}
nothing happens, what am I doing wrong?
You could use the comments_template filter to make WordPress use your plugin's template file rather than the current theme's.
EDIT: based on your edited code: unfortunately you need to have an actual file, the path to which you return in $this->comments_template()...
class MyPlugin{
//add the filter somewhere...
function comments_template($template){
return dirname(__FILE__) . "/my_comments_template.php";
}
}
The file plugin_dir/my_comments_template.php must exist, otherwise WP falls back on the default theme's comments.php. See wp-includes/comment-template.php on lines 911-917.
In plugin_dir/my_comments_template.php you could call `MyPlugin::do_comments() or something like that. I don't know any other way around this. Let me know if you find a better way.
Cheers, Chris
