README

A minimal WordPress polyfill providing mdash functions for consistent empty value handling.

Description

This package provides two simple utility functions for WordPress development that handle empty values using the HTML em dash entity (—). Since WordPress doesn't include built-in mdash functions, this fills that gap with a minimal, focused implementation.

Installation

Install via Composer:

composer require arraypress/wp-mdash

Usage

Basic Functions

Return em dash for empty values
echo mdash( $value );        Returns '—' if empty, otherwise the value
echo mdash( '' );            Returns '—'
echo mdash( null );          Returns '—'
echo mdash( false );         Returns '—'
echo mdash( 0 );             Returns '—'
echo mdash( 'Hello' );       Returns 'Hello'

Direct output
mdash_e( $value );           Echoes '—' if empty, otherwise echoes the value

Common Use Cases

In admin tables
echo '<td>' . mdash( $user->last_login ) . '</td>';

In reports
echo 'Total Sales: ' . mdash( $sales_count );

In user profiles  
echo 'Bio: ' . mdash( $user_bio );

Direct output in templates
<div class="price"><?php mdash_e( $product->sale_price ); ?></div>

Why This Exists

WordPress has many display functions but lacks a simple way to handle empty values with em dashes—a common pattern in professional interfaces. This polyfill provides that missing functionality with just two functions, following WordPress coding standards and conventions.
