Austin

This plugin adds a jQuery file that will position a fixed bar at the top of your browser screen to show announcements (controlled by a custom post type [CPT]) on each page load. Built with simple HTML and javascript.
Upon installation, you can choose the prefix for your post type. Be sure to choose wisely, because once you publish your first post this can’t be changed. If you are having problems with redirects visit your permalinks page to flush your rewrite rules by visiting your permalinks settings page (no save needed).
New: A cookie is added and deleted when you toggle the bar open and closed. Depending on the position of the bar when you leave the page is where it will be when you re-visit the site.

The Link 
Please be aware when publishing a post, as of right now, you have to fill in the content with non-html text and add a link into the link field. This link is really the permalink and is what gets counted when clicked on. It will also revert to the home page if missing, and not count against the counter. If you’re getting 404 issues when visiting the permalink page, please refer to the FAQ section.
<h3>Future Releases</h3>
This plugin is brand new and has some future planes.

<h3>Usage</h3>
<h3>Creating a new campaign</h3>
<ol>
<li>Go to <code>WooCommerce → Smart Campaigns</code> and click Add New Campaign.</li>
<li>(Optional) Choose a template at the top (Flash Sale, Weekend Deal, Clearance) to prefill common settings.</li>
<li>Fill out the Campaign Details card:
<ul>
<li>Campaign Name – internal name shown in the admin list.</li>
<li>Campaign Type – Flash Sale, Weekend Deal, or Clearance (used for labels and badges).</li>
<li>Announcement Bar Text – the message shown in the storefront bar.</li>
<li>Status – Draft, Scheduled, Active or Expired.</li>
</ul>
</li>
<li>Configure the Discount Settings card:
<ul>
<li>Discount Type – Percentage or Fixed Amount.</li>
<li>Discount Value – required; for example <code>20</code> for 20% or <code>15</code> for a 15‑unit fixed discount.</li>
<li>Limit to Categories – leave blank to apply to all products, or select one or more product categories to target only those items.</li>
</ul>
</li>
<li>Configure the Schedule & Appearance card:
<ul>
<li>Start Date & Time – when the campaign should begin (optional; leave empty to start immediately when set to Active).</li>
<li>End Date & Time – when the campaign should end (optional; leave empty for open‑ended campaigns).</li>
<li>Quick fill buttons – 24 hours, This Weekend, or Next 7 Days to speed up date entry.</li>
<li>Bar Background Color & Countdown Timer Color – control the storefront bar appearance; the live preview updates as you type.</li>
</ul>
</li>
</ol>
<h3>Advanced options</h3>
These options appear in the Discount Settings or Schedule & Appearance areas:
<ul>
<li>Test Mode (checkbox) – when enabled, the campaign is only visible and applied to users who can manage WooCommerce (store admins). Use this to preview the bar, badges and discounts before going live.</li>
<li>Minimum Cart Value – if set above zero, the discount only applies when the cart subtotal is at least this amount.</li>
<li>Exclude Products Already On Sale – if enabled, products that already have a WooCommerce sale price keep their own sale and are not further discounted by the campaign.</li>
<li>Social Proof Text – small line of text shown in the announcement bar (for example “Over 500 orders placed this week!”).</li>
</ul>
<h3>How discounts are applied</h3>
<ul>
<li>Discounts are applied dynamically via WooCommerce price filters – the plugin never modifies product prices in the database.</li>
<li>Only one active campaign is used for pricing at a time (the most recently created active campaign).</li>
<li>If Limit to Categories is empty, discounts and urgency UI apply to all products (subject to minimum cart value, test mode and exclude‑on‑sale settings).</li>
<li>If one or more categories are selected, discounts and urgency elements (badge, price HTML, product urgency text) only appear on products belonging to those categories.</li>
</ul>
<h3>Scheduled campaigns</h3>
<ul>
<li>Set Status = Scheduled and fill Start Date and/or End Date.</li>
<li>The plugin uses Action Scheduler to:
<ul>
<li>Automatically switch the campaign to Active at the start time.</li>
<li>Automatically switch it to Expired at the end time.</li>
</ul>
</li>
<li>If WP‑Cron or Action Scheduler are not running correctly, the Smart Campaigns admin screen shows a clear warning with a link to documentation.</li>
</ul>
<h3>Embedding a countdown with shortcodes or a block</h3>
You can drop a campaign countdown into any post, page, page-builder layout, or sidebar widget.
Shortcodes:
<ul>
<li><code>[scm_countdown]</code> — uses the currently active campaign.</li>
<li><code>[scm_countdown id="5"]</code> — countdown for campaign #5.</li>
<li><code>[scm_countdown id="active" label="Sale ends in" show_label="1"]</code> — customise the label.</li>
<li><code>[scm_banner]</code> — render the full announcement bar inline (not fixed) for a specific section of a landing page.</li>
</ul>
Gutenberg block: Search for “SCM Campaign Countdown” in the block inserter. Set the campaign ID (or <code>active</code>) and label in the sidebar.
<h3>Low-stock urgency</h3>
When a campaign is active, products with WooCommerce stock management enabled will show a small “Only X left in stock!” badge once their <code>stock_quantity</code> is at or below the configured threshold (default: 10). Configure under Smart Campaigns → Settings.
<h3>Email notifications</h3>
Enable Smart Campaigns → Settings → Email me on campaign start / end to receive a plain-text email at your site admin address whenever a scheduled campaign auto-starts or auto-expires.
<h3>Bar position</h3>
Choose top or bottom of page under Smart Campaigns → Settings → Announcement bar position.
