<h3>Usage</h3>
<h3>1. Aktivierung und Zugriff</h3>
<p>Nach der Installation findest du den Menüpunkt unter:<br />
<strong>Einstellungen <span aria-hidden="true" class="wp-exclude-emoji">→</span> Wartungshinweis</strong></p>
<p>Hier kannst du das Verhalten des Plugins vollständig steuern.</p>
<h3>2. Admin-Warnleiste (Dashboard-Hinweis)</h3>
<p>Diese Leiste wird oben im WordPress-Dashboard angezeigt, für alle oder ausgewählte Benutzerrollen.</p>
<p><strong>Einstellungen:</strong><br />
– <strong>Wartung aktiv (Checkbox):</strong> Zeigt den Hinweis sofort an, auch außerhalb eines Zeitfensters.<br />
– <strong>Von / Bis (Datum + Uhrzeit):</strong> Optionales Zeitfenster, innerhalb dessen der Hinweis automatisch aktiv ist.<br />
– <strong>Nachricht:</strong> Freitext oder Vorlage mit Platzhaltern:<br />
  – <code>{WEEKDAY}</code>, <code>{DATE}</code>, <code>{FROM}</code>, <code>{TO}</code>, <code>{TZ}</code><br />
  – <code>{DATETIME_FROM}</code>, <code>{DATETIME_TO}</code>, <code>{WEEKDAY_TO}</code>, <code>{DATE_TO}</code><br />
– <strong>Sichtbar für Rollen:</strong> Bestimme, welche Rollen die Nachricht sehen (z. B. nur Administratoren oder Redakteure).</p>
<p>💡 <em>Wenn kein Text eingegeben ist, erzeugt das Plugin automatisch eine Standardmeldung auf Basis des Zeitfensters.</em></p>
<h3>3. Frontend-Wartungsmodus</h3>
<p>Wenn aktiviert, ersetzt das Plugin deine öffentliche Website während der Wartungszeit durch eine <strong>Maintenance Landingpage</strong>.</p>
<p><strong>Einstellungen:</strong><br />
– <strong>Frontend Maintenance aktiv:</strong> Schaltet den Modus ein.<br />
– <strong>Bypass für eingeloggte Nutzer:</strong> erlaubt angemeldeten Benutzern, die Seite weiterhin normal zu sehen.<br />
– <strong>Landingpage-Modus:</strong><br />
  1. <strong>WordPress-Seite:</strong> Nutzt den Inhalt einer bestehenden Seite (Dropdown-Auswahl).<br />
  2. <strong>Custom HTML:</strong> Du kannst eine eigene HTML-Struktur direkt im Textfeld hinterlegen.<br />
  3. <strong>Template-Datei:</strong> Wähle eine HTML-Datei aus dem Plugin-Verzeichnis (<code>assets/maintenance/templates/</code>).</p>
<p>💡 <em>Das Standard-Template <code>default.html</code> zeigt Titel, Nachricht und Zeitraum automatisch an.</em></p>
<h3>4. Templates anpassen</h3>
<p>Eigene Templates kannst du einfach ergänzen:</p>
<ol>
<li>Erstelle im Verzeichnis <code>/assets/maintenance/templates/</code> eine Datei, z. B. <code>blue-theme.html</code>.</li>
<li>Verwende Platzhalter für dynamische Inhalte:
<ul>
<li><code>{{TITLE}}</code>, <code>{{MESSAGE}}</code>, <code>{{SITE_NAME}}</code>, <code>{{WINDOW}}</code></li>
<li><code>{{FROM}}</code>, <code>{{TO}}</code>, <code>{{DATE}}</code>, <code>{{DATE_TO}}</code>, <code>{{TZ}}</code></li>
</ul>
</li>
<li>Füge eigene CSS-Dateien unter <code>/assets/maintenance/css/</code> hinzu und binde sie im Template mit <code><link></code> ein.</li>
</ol>
<h3>5. Verhalten und Priorität</h3>
<p>Das Plugin aktiviert die Frontend-Wartung, wenn:<br />
– „Frontend Maintenance aktiv“ <strong>oder</strong><br />
– ein gültiges <strong>Von/Bis-Zeitfenster</strong> aktiv ist.</p>
<p>Während dieser Zeit:<br />
– wird HTTP <strong>503 (Service Unavailable)</strong> gesendet,<br />
– ein <code>Retry-After</code> Header gesetzt,<br />
– und <code>noindex, nofollow</code> Meta-Tags ausgegeben (SEO-freundlich).</p>
<p>Nach Ablauf oder Deaktivierung wird die normale Seite automatisch wieder angezeigt.</p>
<h3>6. Deinstallation</h3>
<p>Beim Entfernen über „Plugins <span aria-hidden="true" class="wp-exclude-emoji">→</span> Deinstallieren“:<br />
– werden alle Optionen (<code>ammsg_options</code>, alte <code>ck_admin_maintenance_opts</code>) gelöscht,<br />
– in Multisite-Umgebungen automatisch für alle Sites bereinigt.</p>
<h3>7. Tipps & Best Practices</h3>
<ul>
<li>Verwende <strong>UTC+X Zeitzonen</strong> bewusst – die Pluginzeiten richten sich nach der WordPress-Zeitzone.</li>
<li>Wenn du Templates bearbeitest, achte auf <strong>UTF-8 ohne BOM</strong>.</li>
<li>Du kannst über Filter eigene Verhalten ergänzen:
<ul>
<li><code>ammsg_uninstall_option_keys</code> – eigene Optionen löschen</li>
<li><code>ammsg_frontend_template_replacements</code> – Platzhalter erweitern</li>
</ul>
</li>
</ul>

<h3>Types of On-site Messages</h3>
<p>Using this plugin, online shop owners can craft any kind of messages, notices or alerts to deliver what they need to inform or tell customers & visitors and place in the relevant position to make sure they can take effect as expected. Basically, users can process 3 types of messages: general notices, marketing messages & transactional notices.</p>
<h4>General notices</h4>
<p>General notices can be placed across the store, on all pages or custom selected pages. It’s often about the recent changes or important pieces of information that customers should know before adding any products to the cart or placing their order.</p>
<ul>
<li>Holiday break or vacation leave notices</li>
<li>Changes in business hours of the store</li>
<li>Special management amid crisis, illness, covid, etc.</li>
<li>General policy notices</li>
</ul>
<h4>Marketing Messages</h4>
<p>As a marketing strategy, showing on-site messages is one of the most proficient but still simple ways to inform and educate visitors about what they need to pay attention to.</p>
<ul>
<li>Introduce limited-time offers, give away, or sales events</li>
<li>Cross-sell & up-sell product suggestion</li>
<li>Remind when the product is on sale or ready for preorder</li>
<li>Urge customers with the low-threshold notice</li>
<li>Notify when a product is nearly out of stock or will be restocked</li>
<li>Remind customers of checking out valid discounts, gifts, or coupons</li>
<li>Personalized message: related products that buyers might be interested in</li>
<li>Encourage social sharing and referral for products</li>
</ul>
<h4>Transactional Notices</h4>
<p>Transactional notices are reminders of the buyer’s account, the special points that customers need to pay attention to during the payment process or delivery time. Any delays or special notes can be informed to customers promptly right on the cart and checkout pages to make sure they have acknowledged everything they need to know. This will avoid misunderstandings and reduce the refund/ return rate.</p>
<ul>
<li>Notify the order processing time or purchase limit</li>
<li>Encourage order value increase for free shipping or gifts</li>
<li>Introduce available payment methods, installment or quote</li>
<li>Inform the estimated packing and delivery time</li>
<li>Custom cart and checkout messages</li>
<li>Guide customers in filling out billing details & addresses</li>
<li>Encourage buyers to subscribe or log in when purchasing</li>
</ul>
<h4>Real-time Automatic Messages</h4>
<p>Users can combine a number of date and time conditions to configure how and when the messages are visible on the site. When users insert the built-in shortcode into the message text, the displayed date and time will be calculated in real time. To strengthen the effectiveness and emphasize the urgency of the time-sensitive content, they can also use the shortcode from the <a href="https://wordpress.org/plugins/wpc-countdown-timer/" rel="ugc">WPC Countdown Timer</a> plugin to show a beautiful real-time countdown clock.</p>
<p>The conditions can be complex or simple based on users’ preferences and configurations: date & time, user role, product categories, tags, brands, types, attributes, etc. It’s even possible to filter special product types such as <a href="https://wordpress.org/plugins/woo-product-bundle/" rel="ugc">Smart Bundles</a>, <a href="https://wordpress.org/plugins/wpc-composite-products/" rel="ugc">Smart Composite</a> and <a href="https://wordpress.org/plugins/wpc-grouped-product/" rel="ugc">Smart Grouped Products</a> to display customized messages on them.</p>
<p>The <a href="https://wordpress.org/plugins/wpc-brands/" rel="ugc">WPC Brands</a> is a free plugin from WPClever that allows users to create and manage products by brand. Combining these two plugins, users can process and display messages on branded products with ease.</p>
<p>WPC Smart Messages will automatically provide the precise display based on the real-time calculation of the date-time, stock, item count, cart count, cart total, discount amount or percentage, product price’s configurations.</p>
<p>Sample messages:</p>
<ul>
<li>The Black Friday event will start in 2 days 10 hours.</li>
<li>There are 1000 people interested in this product. 200 customers have pre-ordered this.</li>
