I'm trying to create a second single.php for my WordPress theme.
The first single is used with get_permalink() but it's impossible to create another single2.php
How is this feasible?
I'd like to use the single2.php the same way as the regular single.php
I've seen some tutorials but every time they associate the single2.php with the creation of WP categories and I know it's doable without it. I just don't know how.
Open single.php in your HTML editor. Delete the contents of single.php and place the following code in it. Substitute the number 3 for the Category ID # you noted.
<?php
$post = $wp_query->post;
if ( in_category('3') ) {
include(TEMPLATEPATH . '/single2.php');
} else {
include(TEMPLATEPATH . '/single1.php');
}
?>
You should have a look at the Wordpress Template Hierarchy, it could give you tips to do that :
You could create a page-{slug}.php or a page-{id}.php file for example, but it's not the nicest way as it's only for a specific slug or specific id.
I'd recommend to create a template file, where you can create your page. This template can be reuse for several pages !

Pretty much every guide ive come across for adding php pages to Wordpress involves adding it at the theme level. e.g. How to add a PHP page to WordPress?. I want to add a new public facing page to multiple sites via a plugin. I dont want to have to add this to dozens of themes. If i can add it ad the plugin level it will work for all sites.
I have this working, but i need some way of injecting this into a theme. In order to get the sidebar and stuff without having to add custom css for each theme.
Ive started by adding a rewrite rule
RewriteRule ^mypage /wp-content/plugins/myplugin/mypage.php [QSA,L]
Then page.php contains
require_once('../../../wp-blog-header.php');
get_header();
//custom php content
//get_sidebar(); // how to get this working.
get_footer();
This also works, but the problem im having is with sidebars. Some themes dont have them and others do. Not all sidebars are 30% etc. I dont know how to build the div structure here to make it work. Some themes are 100% page width, but this looks ugly when viewed on other themes that are a fixed width. I have been able to come up with some compromises, but id rather be able to do this right.
In summery my main question here is. Is it possible to call a method that will inject html into a theme page. e.g. generate_page($html);. This method will then go to page.php of the theme and inject $html into the content area of the theme.
Edit
In an attempt to dynamically inject content into an unknown theme ive done the following
global $post;
$post->post_content = "TEST PAGE content";
$post->post_title = "Page Title";
$post->post_name = "test-page";
include get_template_directory()."/page.php";
This works for some themes and not others. Some themes will display this post just fine, but others (the default wordpres twenty fifteen theme) are displaying this post and then every other post in the database after it. Im not sure where or why its pulling all of these posts, but if i can get it to stop it looks like this will be a valid solution.
Then u could try to load a specific template page in specific case.
function load_my_template( $template )
{
if( is_page() )
$template = plugin_dir_path(__FILE__) . "dir_to/my_template.php";
return $template;
}
Or change the content that is use on loading page
function load_my_content( $content )
{
global $post;
$id = $post->ID;
if( is_page() )
{
ob_start();
include plugin_dir_path(__FILE__) . "dir_to/my_template.php";
$content = ob_get_clean();
}
return $content;
}
In your __construct()
add_filter('template_include', array($this,'load_my_template') );
add_filter("the_content", array($this,"load_my_content" ) );
add_filter("get_the_content", array($this,"load_my_content" ) );
Hope that help u.
Tell me if it's not corresponding with your question.
Is it possible to create a tag.php template that when you navigate to the url www.domain.com/tag/architecture/ it will display all the custom posts that have been tagged with that specific tag? And so on for various other tags?
What code will I need to include on my template?
Yes You can create,below is the code i used to display custom post type "knowledge"
<?php
global $query_string;
$posts = query_posts($query_string.'&post_type=knowledge');
if ( have_posts() ) while ( have_posts() ) : the_post();
?>
<?php the_title(); ?>
<?php endwhile; // end of the loop. ?>
This will help you understand hierarchy of templates:
http://codex.wordpress.org/images/1/18/Template_Hierarchy.png
Use of $query_string (example) available here:
https://developer.wordpress.org/reference/functions/query_posts/
According to the template hierarchy, you can create a file called tag.php which will be used instead of index.php if a tag page is displayed. You can also prepare separate templates for specific tags.
The best way is to start by creating a copy of your theme's index.php and calling it tag.php, this way you'll have some basic code working. Then you can modify tag.php to fit your needs - probably by editing The Loop, or maybe changing some includes if your theme loads the loop from separate file. (but in this case you should consider editing index.php to load some other loop for tag pages - is_tag() may come in handy)
Is there an easy way to change the WP default template hierarchy?
For instance;
Say I want to change my theme directory structure so that it completely changes from the Template Hierarchy suggested here based upon conditionals:
http://codex.wordpress.org/Template_Hierarchy
if I wanted to make sure that for all page types (is_single() is_home() etc) it always opens one template file which then instigates my own pattern to provide the output?
Thanks very much!
I would do it like this:
Easy to read and works well
single.php:
<?php include_once('template-you-want.php');
home.php:
<?php include_once('template-you-want.php');
If you don't want to have these two files at all do it in index.php:
<?php
// at the very top
if (is_single()){
include_once('template-you-want.php');
die(); // don't continue
}
if (is_home()){
include_once('template-you-want.php');
die(); // don't continue
}
Goal - have a section of my sidebar that is conditional depending on what page I'm on. All child pages of the selected page should also show the conditional section.
There are at least two ways to do this - 1) have all the conditional hooks and resulting code in one sidebar file and, 2) have multiple sidebar.php documents and call them based off what pages are being visited.
I've pretty much failed at both ways so far... :( I'm working on the second method right now though, because I think it might be more flexible long term. Anyway, in my page.php I replaced:
<?php get_sidebar() ?>
With
<?php
if (is_page(1997) || $post->post_parent) {
get_sidebar('sidebar-test-may12.php')
}
else { get_sidebar()
} ?>
With the hope of testing the method. What I want to happen is that if the page is page id 1997 or any of its child pages please show sidebar-test-may12.php. Otherwise show the regular sidebar. With the new code the whole page goes blank. Any suggestions or solutions for me? Seems like a common problem, but I haven't been able to figure it out yet. Thanks!
You have a few problems with your code example:
1) $post->post_parent is not being checked against anything else, so it will only return true if it is a child page (not necessarily the child of the page you want to target)
2) get_sidebar() is being called incorrectly. If you want to get 'sidebar-test-may12.php' from your theme folder, you need to call get_sidebar('test-may12')
3) You're missing semicolons after your function calls
So your code should look like this:
<?php
if(is_page(1997) || $post->post_parent == 1997) {
get_sidebar('test-may12'); //get sidebar-test-may12.php
}
else{
get_sidebar(); //get sidebar.php
}
?>
Let me know if that helps.
UPDATE: Bear in mind, $post->post_parent does NOT get the top-most ancestor ID of a child page. If you want to grab the top-level ID regardless of depth, consider doing this:
<?php
$ancestors = get_ancestors(get_the_ID(), 'page');
if(is_page(1997) || end($ancestors) == 1997)
get_sidebar('test-may12'); //get sidebar-test-may12.php
else
get_sidebar(); //get sidebar.php
?>
POSSIBLE SOLUTION: Building off your example and my proposed ancestry check, one thing you can do is have your template check to see if a special sidebar exists in your theme based on the parent page's slug. This way, if you decide a particular page needs a special sidebar for it and all of its children/grandchildren/great-grandchildren/etc. you just need to add it into your theme with a name of 'sidebar-{parent_slug}.php'. So:
<?php
$id = get_the_ID();
$ancestors = get_ancestors($id, 'page');
$top_page = $ancestors ? get_page(end($ancestors)) : get_page($id);
if(locate_template('sidebar-'.$top_page->post_name.'.php'))
get_sidebar($top_page->post_name);
else
get_sidebar();
?>
This way, you don't need a ton of conditionals to decide which Sidebar file to load on a general Page template.
Use some error trapping to show what's going on with your php, either toggling an error log in .htaccess of a simple widget: http://wordpress.org/extend/plugins/error-log-dashboard-widget/
I've hardcoded logic for sidebars, but I've also used WordPress › Widget Logic « WordPress Plugins for my own and client sites. It's easy to use with a simplified version of WP conditionals, like is_category and is_page ('101')
For someone else tackling this same problem -- there is a new plugin out that solves this problem very well. It even makes creating the sidebars easy. You can check it out here:

in wordpress the single page is controlled by single.php theme file. I want to put another link on the single page like "Preview". I want this link to be handled by preview.php. preview.php will be stored in theme directory! how to handle this?
usually I do these using init action hook! if the variable exists in the query string, I perform the action! but how to register a custom script to handle a custom link!
the single page link is like ?p=x and the link to preview will be ?p=x&action=preview
thanks in advance
You could do it old school style. At the very top of your single.php, put:
<?php
if( isset( $_GET['preview'] ) ) {
require( "preview.php" );
die(); # a horrible death
}
?>
