# Genesis Code Snippets

My collection of code snippets that I use while coding the Genesis Framework for WordPress.

Here is my collection of code snippets I use build child themes in [Genesis](https://gregslink.co/try-genesis).

If it's not here, please check out Bill Erickson's [Genesis Quick Tips](http://www.billerickson.net/genesis-quick-tips/), Gary's [Code](http://code.garyjones.co.uk/), or Brian Gardner's [Code](http://www.briangardner.com/code/). Thanks to [Gary J](http://twitter.com/garyj) for advice on cleaning up the code snippets to adhere with coding standards.

NOTE: While all of these functions still work, some may not with Genesis 2.0's new hook structure. Check out [this visual guide](http://genesistutorials.com/visual-hook-guide/) to make adjustments.

Quickly navigate to a section:

**Add viewport for responsive (mobile) design**

```php
/** Add Viewport meta tag for mobile browsers */

}
```

## Template

**Place WP-Cycle (must have [WP-Cycle](http://wordpress.org/extend/plugins/wp-cycle/) plug-in installed first)**

genesis_unregister_layout( 'full-width' );
genesis_unregister_layout( 'content-sidebar-sidebar' );
genesis_unregister_layout( 'sidebar-sidebar-content' );
genesis_unregister_layout( 'sidebar-content-sidebar' );
```

**Force Layout**

add_filter( 'genesis_pre_get_option_site_layout', 'child_do_layout' );

/**
 * Force layout.
 *
 * @author Greg Rickaby
 * @since 1.0.0
 */
function child_do_layout( $opt ) {
	$opt = 'full-width-content'; // You can change this to any Genesis layout.
	return $opt;
}
```

**Use the Genesis Custom Loop**

```php
remove_action( 'genesis_loop', 'genesis_do_loop' );
add_action( 'genesis_loop', 'custom_loop' );

/**
 * Remove default loop. Execute Custom Loop Instead.
 *
 * @author Greg Rickaby
 * @since 1.0.0
 */
function custom_loop() {
	global $paged;

	$args = array(
		'category_name'  => 'Blog',
		'order'          => 'asc',
		'order_by'       => 'title',
		'paged'          => $paged,
		'posts_per_page' => 5,
	);

	genesis_custom_loop( $args );
}

genesis();
```

**Custom Page Template**

```php
<?php
/*
Template Name: Custom Page Template
*/

// Remove page title.
remove_action( 'genesis_entry_header', 'genesis_do_post_title' );

// Force full width content (optional).
add_filter( 'genesis_pre_get_option_site_layout', '__genesis_return_full_width_content' );

// Remove default Genesis loop.
remove_action( 'genesis_loop', 'genesis_do_loop' );

// Add new custom loop.
add_action( 'genesis_loop', 'child_custom_loop' );

/**
 * Execute child loop.
 */
function child_custom_loop() { ?>
	<!-- custom code here -->
<?php }

genesis();
```

**Use the Genesis Grid Loop in `front-page.php`**

```php
remove_action( 'genesis_loop', 'genesis_do_loop' );
add_action( 'genesis_loop', 'child_grid_loop_helper' );

/** Add support for Genesis Grid Loop */
function child_grid_loop_helper() {
	if ( function_exists( 'genesis_grid_loop' ) ) {
		remove_action( 'genesis_before_post_content', 'generate_post_image', 5 );

		genesis_grid_loop( array(
			'features'              => 2,
			'feature_image_size'    => 'large',
			'feature_image_class'   => 'aligncenter post-image',
			'feature_content_limit' => 0,
			'grid_image_size'       => 'grid',
			'grid_image_class'      => 'alignleft post-image',
			'grid_content_limit'    => 0,
			'more'                  => __( 'Continue reading...', 'genesis' ),
			'posts_per_page'        => 6,
		) );
	} else {
		genesis_standard_loop();
	}
}

genesis();
```

**Filter out duplicate posts in the WordPress Loop**

```php
$do_not_duplicate = array();

query_posts( 'cat=featured&showposts=6' );

while ( have_posts() ) : the_post();
	$do_not_duplicate[] = $post->ID;
	// Do stuff.
endwhile;

wp_reset_query();
```

**Add Widgets And WP-Cycle To `front-page.php`**

```php
remove_action( 'genesis_after_post_content', 'genesis_post_meta', 10 );
remove_action( 'genesis_loop', 'genesis_do_loop' );
add_action( 'genesis_before_loop', 'wp_cycle' );
add_action( 'genesis_loop', 'child_home_loop_helper' );

/**

 *
 * @author Greg Rickaby
 * @since 1.0.0
 */
function child_home_loop_helper() { ?>
	<div id="homepage_widgets">
		<div class="column1">
			<ul>
				<?php if ( ! function_exists( 'dynamic_sidebar' ) || ! dynamic_sidebar( 'Home 1' ) ) { ?><?php } ?>
			</ul>
		</div>
		<div class="column2">
			<ul>
				<?php if ( ! function_exists( 'dynamic_sidebar' ) || ! dynamic_sidebar( 'Home 2' ) ) { ?><?php } ?>
