I'm using ACF to build blocks.
Here's a simple function I've written via functions.php:
<?php
function my_test_function() {
if ( is_page_template( 'template-parts/blocks/hero/hero.php' ) ) {
echo '<p>I appear via the hero.php template.</p>';
}
if ( is_page_template( 'template-parts/blocks/video/video.php' ) ) {
echo '<p>I appear via the video.php template.</p>';
}
}
?>
Here's how I call the function via hero.php and video.php
<?php
my_test_function();
?>
When I test this, nothing appears. I'm guessing the is_page_template function doesn't work in this instance as it's technically not a page template.
Is there another function that might work with ACF block templates?
You could use parse_block() : https://developer.wordpress.org/reference/functions/parse_blocks/ then loop through blocks to check if blockName exist for this page :
function check_if_block_exist($block_handle) {
$post = get_post();
if(has_blocks($post->post_content)) {
$blocks = parse_blocks($post->post_content);
foreach( $blocks as $block ) {
if($block['blockName'] === $block_handle) {
return true;
}
}
return false;
}
}
I am using the following function to call a custom single post overriding the default one single.php
function call_different_single_post($single_template)
{
global $post;
$path = get_stylesheet_directory() . '/includes/templates' . '/';
$single_template = $path. 'single-1.php';
return $single_template;
}
add_filter('single_template', 'call_different_single_post');
It's calling the single-1.php template for the single posts.
Now I want to check this template conditionally so that I can call some other js files like
function call_cust_js_single(){
if( /*..this is single-1.php template..*/){
wp_register_script('cust-js', get_stylesheet_directory_uri() . 'custom.js', false, '1.0.0');
wp_enqueue_script('cust-js');
}
}
add_action('wp_enqueue_scripts', 'call_cust_js_single');
There's a post similar to this but it doesn't quite cover your request. Here's the link here
Here's the valuable code:
add_filter( 'template_include', 'var_template_include', 1000 );
function var_template_include( $t ){
$GLOBALS['current_theme_template'] = basename($t);
return $t;
}
function get_current_template( $echo = false ) {
if( !isset( $GLOBALS['current_theme_template'] ) )
return false;
if( $echo )
echo $GLOBALS['current_theme_template'];
else
return $GLOBALS['current_theme_template'];
}
Now you have the function get_current_template that will return the filename of the template file.
Now edit your header.php file, here's an example:
<?php if('single-1.php' == get_current_template())
{
//load your scripts here
} ?>
It's not as clean as what you were looking for but I think it will help you.
I am struggling really hard with the is_page_template Conditional.
The problem is that when I "include" my template functions file (country_template_functions.php) into my functions.php file, the is_page_template conditional doesn't work anymore.
If I remove the "include(template...)" from my functions.php it does work again, but this is no solution since the file has to be included into the functions.php to make it work.
Can anyone explain me what might be wrong?
The is_page conditional works in both cases.
if (file_exists(THESIS_CUSTOM . '/country_template_functions.php')){
include(THESIS_CUSTOM . '/country_template_functions.php');
}
function test() {
if ( is_page_template( "country_template.php" ) ){
echo "is page template works";
}
}
add_action('thesis_hook_before_header','test');
I am using the Thesis Theme.
EDIT:
This seems to cause the problem but not sure exactly why. It causes that I cannot use the is_page_template after the thesis_hook_before_content_area
add_action('thesis_hook_before_content_area', 'country_page_template_swap_before_content');
function country_page_template_swap_before_content(){
if (is_page()) {
global $post;
global $swapped_post;
$page_template = get_post_meta($post->ID, '_wp_page_template', true);
if($page_template == 'country_template.php'){
update_post_meta($post->ID, '_wp_page_template', 'custom_template.php');
$swap_id = time();
update_post_meta($post->ID, '_country_template_swapped', $swap_id);
$swapped_post = $post;
}
else{
$template_swapped = get_post_meta($post->ID, '_country_template_swapped', true);
if(!empty($template_swapped)){
$swapped_post = $post;
}
}
}
}
i created a custom page named custom_page.php in wordpress and use this as a page template.
i wanted to create my own functions and only target my custom_page.php. this function will be installed as a plugin.
what kind of WP HOOKS should i use, for example i have this code below
function your_function() {
if ( is_page_template('custom_page.php') ) {
echo '<p>This is inserted at the bottom</p>';
{
}
add_action('wp_footer', 'your_function');
i want to only execute this code in my custom_page.php footer area.
[EDIT]
You can use these hooks for page templates.
http://adambrown.info/p/wp_hooks/hook/page_template
Or may be something like this...
add_filter( 'page_template', 'check_the_template' );
function check_the_template( $template ) {
if( 'custom_page.php' == basename( $template ) ) {
// do some things here by calling functions, hooks etc..
}
return $template;
}
If you want to just echo "Hello World" :
add_filter( 'page_template', 'check_the_template' );
function check_the_template( $template ) {
if( 'pagetemplete.php' == basename( $template ) ) {
add_action( 'the_content', 'echofunction' );
}
return $template;
}
function echofunction() {
echo "Hello World";
}
Is it possible for a file in the plugin directory to be used as a custom Page Template?
Also, how do you make a plugin create a page?
I'm developing a plugin for a client based on a theme, he wants this plugin to make sales pages while being able to use his theme on the homepage. This is a product that I'm making for him to market so it needs to be automated all through the plugin.
Is this possible?
EDIT
I have the activation/deactivation hooks in my plugins main file, and it's not working. Here's the code:
$filename = __FILE__;
register_activation_hook($filename, 'superActivation');
register_deactivation_hook($filename, 'superDeactivation');
global $myFile; global $fh; global $stringData; global $filename;
$myFile = "testFile.txt";
$stringData = "Testing\n";
$fh = fopen($myFile, 'w') or die("can't open file");
function superActivation() {
global $myFile; global $fh; global $stringData; global $filename;
fwrite($fh, $stringData);
fclose($fh);
}
function superDeactivation() {
$myFile = "testFile.txt";
unlink($myFile);
}
You can do this with the template_redirect hook. Here's my code to manually replace the template for a custom post type with one in the theme if there isn't one in the template folder. Put this in your plugin file and then put a folder underneath your plugin called themefiles with your default theme files.
//Template fallback
add_action("template_redirect", 'my_theme_redirect');
function my_theme_redirect() {
global $wp;
$plugindir = dirname( __FILE__ );
//A Specific Custom Post Type
if ($wp->query_vars["post_type"] == 'product') {
$templatefilename = 'single-product.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
//A Custom Taxonomy Page
} elseif ($wp->query_vars["taxonomy"] == 'product_categories') {
$templatefilename = 'taxonomy-product_categories.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
//A Simple Page
} elseif ($wp->query_vars["pagename"] == 'somepagename') {
$templatefilename = 'page-somepagename.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
}
}
function do_theme_redirect($url) {
global $post, $wp_query;
if (have_posts()) {
include($url);
die();
} else {
$wp_query->is_404 = true;
}
}
You CAN add page templates from a plugin very easily by manipulating the page cache.
To customise, simply edit the following code block within the __construct method;
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
This is designed for a plugin (the template files are searched for in the root directory of the plugin). This can be changed if desired - check out my full tutorial http://www.wpexplorer.com/wordpress-page-templates-plugin/ for greater detail on this solution. These files are also in exactly the same format as if they were to be included directly in a theme.

I hope this helps you in what you want to do :)
the code david posted above almost works for me. but it seems to blanket over all posts and pages for me. This code below works great for adding a template to a single post type that is created by my main plugin file
function get_book_post_type_template($single_template) {
global $post;
if ($post->post_type == 'books') {
$single_template = dirname( __FILE__ ) . '/themefiles/single-books.php';
}
return $single_template;
}
add_filter( "single_template", "get_book_post_type_template" ) ;
but I'm having trouble getting it to work with a custom page templates that don't have a post_type or has a post_type = page for instance lets say the custom page is an auxiliary member login page to see my custom posts. in my case this file is called myaccount.php and i've included it in a subfolder within my plugin folder named themefiles.
//Add Page and Post Template Files to Current Theme
add_action("template_redirect", 'my_account_redirect');
function my_account_redirect() {
global $wp;
//Set myAccount Custom Page Template
if (isset($wp->query_vars['pagename'] ) == "myaccount") {
$templatefilename = 'myAccount.php';
if (file_exists(dirname( __FILE__ ) . '/themefiles/' . $templatefilename)) {
$return_template = dirname( __FILE__ ) . '/themefiles/' . $templatefilename;
}
do_account_redirect($return_template);
}
}
//Finishing setting templates
function do_account_redirect($url) {
global $post, $wp_query;
if (have_posts()) {
include($url);
die();
} else {
$wp_query->is_404 = true;
}
}
when i do the above code the myaccount template shows up on all pages except for home which i believe is because it is set to a blogroll instead of a static page
I cannot reply to user1912899, but their recommendation seems to be the most elegant solution. To use a custom template to override single-post.php, I've implemented the following code. This will work for any custom single-****.php file you add to your plugin. If it doesn't exist, it just falls back to what WordPress normally uses.
add_action('template_include', 'my_template_include');
function my_template_include($template) {
$file = dirname( __FILE__ ).'/theme/single-'.get_post_type().'.php';
if(file_exists($file)) {
$template = $file;
}
return $template;
}
