Use the WordPress locate_template() function within PHP’s include(), instead of get_template_part().
<?php
$var = 'Hello World!';
include(locate_template('file/path/filename.php'));
?>
If the wordpress content editor is adding extra <p></p> tags, this function will clean it up
function remove_empty_p( $content ){
// clean up p tags around block elements
$content = preg_replace( array(
'#<p>\s*<(div|aside|section|article|header|footer)#',
'#</(div|aside|section|article|header|footer)>\s*</p>#',
'#</(div|aside|section|article|header|footer)>\s*<br ?/?>#',
'#<(div|aside|section|article|header|footer)(.*?)>\s*</p>#',
'#<p>\s*</(div|aside|section|article|header|footer)#',
), array(
'<$1',
'</$1>',
'</$1>',
'<$1$2>',
'</$1',
), $content );
return preg_replace('#<p>(\s| )*+(<br\s*/*>)?(\s| )*</p>#i', '', $content);
}
To remove categories and tags from the menu option on the admin side bar
function my_remove_sub_menus() {
// remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=category');
remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=post_tag');
} add_action('admin_menu', 'my_remove_sub_menus');
This examplue uses a hypothetical ACF called "date" (called with get_field('date'))
This post was made <?php echo human_time_diff( strtotime(get_field('date')), current_time( 'timestamp' ) ); ?> ago
Three ways to link to a wordpress page based on its name
<a href="<?php echo get_permalink( get_page_by_path( 'map' ) ) ?>">Link</a>
<a href="<?php echo get_permalink( get_page_by_title( 'Map' ) ) ?>">Link</a>
<a href="<?php echo home_url( '/map/' ) ?>">Link</a>
Changes the tel: link to a text message link when being viewed on mobile
<a href="<?php if (wp_is_mobile()) { echo 'sms://+1'; } else { echo 'tel:'; } ?>4044774941">4044774941</a>
function the_slug($echo=true){
$slug = basename(get_permalink());
do_action('before_slug', $slug);
$slug = apply_filters('slug_filter', $slug);
if( $echo ) echo $slug;
do_action('after_slug', $slug);
return $slug;
}
If you want to only display the post if it has content, first add this function to functions.php
function empty_content($str) {
return trim(str_replace(' ','',strip_tags($str))) == '';
}
Then wrap the content in the loop in
if (!empty_content($post->post_content)) {
the_content();
} else {
You didn't put any content in the post
}
This example includes a structure that dynamically pulls content from templates. The templates that will be dynamically pulled will correspond with the $query_type and the $types. For the below code, 4 temples would need to be created in the parts/content folder:
-search-post.php
-search-custom_type_1.php
-search-custom_type_2.php
-search-custom_type_4.php
And cycle through the loop with:
<?php
if( have_posts() ){
$types = array('post', 'custom_type_1', 'custom_type_2', 'custom_type_4');
$query_type = 'search';
foreach( $types as $type ){
while( have_posts() ){
the_post();
if( $type == get_post_type() ){
get_template_part('parts/content/' . $query_type, $type);
}
}
rewind_posts();
}
}
?>
To use the Google Maps ACF plugin, first register a Google Maps API key https://developers.google.com/maps/documentation/javascript/get-api-key
Add jquery, API script with API Key, and this minified script to header
<script src="https://code.jquery.com/jquery-3.1.1.min.js" integrity="sha256-hVVnYaiADRTO2PzUGmuLJr8BLUSjGIZsDYGmIJLv2b8=" crossorigin="anonymous"></script>
<script src="https://maps.googleapis.com/maps/api/js?key=xxxxxxxxxxxxxxxxxxx_xxxxxxxxxxx"></script>
<script type="text/javascript">
!function(n){function e(e){var t=e.find(".marker"),r={zoom:16,center:new google.maps.LatLng(0,0),mapTypeId:google.maps.MapTypeId.ROADMAP},g=new google.maps.Map(e[0],r);return g.markers=[],t.each(function(){a(n(this),g)}),o(g),g}function a(n,e){var a=new google.maps.LatLng(n.attr("data-lat"),n.attr("data-lng")),o=new google.maps.Marker({position:a,map:e});if(e.markers.push(o),n.html()){var t=new google.maps.InfoWindow({content:n.html()});google.maps.event.addListener(o,"click",function(){t.open(e,o)})}}function o(e){var a=new google.maps.LatLngBounds;n.each(e.markers,function(n,e){var o=new google.maps.LatLng(e.position.lat(),e.position.lng());a.extend(o)}),1==e.markers.length?(e.setCenter(a.getCenter()),e.setZoom(16)):e.fitBounds(a)}var t=null;n(document).ready(function(){n(".acf-map").each(function(){t=e(n(this))})})}(jQuery);
</script>
Paste the Key into the following code and put it in functions.php
function my_acf_google_map_api( $api ){
$api['key'] = 'xxxxxxxxxxxxxxxxxxx_xxxxxxxxxxx';
return $api;
} add_filter('acf/fields/google_map/api', 'my_acf_google_map_api');
Executing the map on the page. The code will need to be within the Loop.
<div class="about-offices">
<div class="about-office">
<?php if (get_field('office__address')) { ?>
<div class="about-address">
<?php the_field('office__address'); ?>
</div>
<?php } ?>
<?php if (get_field('office__map')) { ?>
<?php $location = get_field('office__map'); ?>
<?php if( !empty($location) ): ?>
<div class="acf-map">
<div class="marker" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>"></div>
</div>
<?php endif; ?>
<?php } ?>
</div>
</div>
Last, style the .acf-map class and add this conflict fix to the css
.acf-map {
width: 100%;
height: 400px;
}
/* fixes potential theme css conflict */
.acf-map img {
max-width: inherit !important;
}
Example of functions.php addition if you want to change "Posts" to "News"
function newproject_change_post_label() {
global $menu;
global $submenu;
$menu[5][0] = 'News';
$submenu['edit.php'][5][0] = 'News';
$submenu['edit.php'][10][0] = 'Add News';
$submenu['edit.php'][16][0] = 'News Tags';
}
function newproject_change_post_object() {
global $wp_post_types;
$labels = &$wp_post_types['post']->labels;
$labels->name = 'News';
$labels->singular_name = 'News';
$labels->add_new = 'Add News';
$labels->add_new_item = 'Add News';
$labels->edit_item = 'Edit News';
$labels->new_item = 'News';
$labels->view_item = 'View News';
$labels->search_items = 'Search News';
$labels->not_found = 'No News found';
$labels->not_found_in_trash = 'No News found in Trash';
$labels->all_items = 'All News';
$labels->menu_name = 'News';
$labels->name_admin_bar = 'News';
} add_action( 'admin_menu', 'newproject_change_post_label' );
add_action( 'init', 'newproject_change_post_object' );
function newproject_work_post_type () {
$labels = array (
'name' => 'Work',
'singular_name' => 'Work Item',
'add_new' => 'Add Work Item',
'all_items' => 'All Work',
'add_new_item' => 'Add Work Item',
'edit_item' => 'Edit Work Item',
'new_item' => 'New Work Item',
'view_item' => 'View Work Item',
'search_item' => 'Search Work',
'not_found' => 'No Work Items Found',
'not_found_in_trash' => 'No Work Found In Trash',
'parent_item_colon' => 'Parent Work Item'
);
$work = array(
'labels' => $labels,
'public' => true,
'has_archive' => true,
'publicly_queryable' => true,
'query_var' => true,
'rewrite' => true,
'capability_type' => 'post',
'hierarchical' => false,
'supports' => array(
'title',
'editor',
'thumbnail',
'revisions',
),
'taxonomies' => array('category', 'post_tag'),
'menu_position' => 5,
'exclude_from_search' => false
);
register_post_type('work',$work);
} add_action('after_setup_theme', 'newproject_work_post_type');
General navigation of a complex post/post relationship.
Add this function to functions.php and change parent and child to corresponding field name.
function my_posts_where( $where ) {
$where = str_replace("meta_key = 'parent_%_child'", "meta_key LIKE 'parent_%_child'", $where);
return $where;
} add_filter('posts_where', 'my_posts_where');
Code for the page you want to display the Reverse Query on. Change posts in 'post_type' => if you are trying to display a custom post type and then change parent and child to corresponding field name.
// args
$args = array(
'post_type' => 'posts',
'meta_query' => array(
array(
'key' => 'parent_%_child',
'value' => '"' . get_the_ID() . '"',
'compare' => 'LIKE'
)
)
);
// get results
$the_query = new WP_Query( $args );
// The Loop
?>
<?php if( $the_query->have_posts() ): ?>
<ul>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endwhile; ?>
</ul>
<?php endif; wp_reset_query(); ?>
In this example, the field project__private is a True/False field. Setting the value to 1 and using compare => != displays only the fields that are not true.
'meta_query' => array(
array(
'key' => 'project__private',
'value' => '1',
'compare' => '!=',
)
)
