<h3>⏱ Schedule when you want</h3>
<p>Define start and end dates so snippets appear only when needed — ideal for campaigns, seasonal banners, or compliance notices.</p>
<h3>📍 Publish where you want</h3>
<p>Inject HTML, JavaScript, or CSS styles into any WordPress hook — Classic or Block Hook — without editing templates. Embed blocks directly inside posts, pages, or widgets using shortcodes.</p>
<h3>🌍 Filter where you want</h3>
<p>Control visibility across WordPress sections: all, frontend, posts, pages, backend (Admin), authentication, and system pages. Apply filters to selected posts or pages for complete flexibility.</p>
<h3>🌐 Target who you want</h3>
<p>Use geotargeting to display blocks only to visitors from selected countries. Configure rules to include or exclude specific regions.</p>
<h3>🔒 Manage safely by whom you want</h3>
<p>Administrators can use Raw Mode (unfiltered output) or Safe Mode (sanitized injection). Non-admins can be granted limited Safe Mode access via the <code>wpsc_admin</code> capability, making delegation secure.</p>
<h3>🗂 Revision when you want</h3>
<p>Retrieve, compare, and restore block editor content with full revision management. Delete outdated revisions safely to keep the database clean and audit-friendly.</p>
<h3>🖊️ Edit how you want</h3>
<p>Includes a built-in editor with dedicated sections for HTML, CSS, and JavaScript, plus Preview and Error panels. Syntax highlighting improves readability, while instant error feedback ensures safe workflows.</p>
<h3>✅ Why WP Smart Content?</h3>
<p>By combining scheduling, hook targeting, filtering, geotargeting, role-based permissions, revisioning, and a syntax-highlighted editor, WP Smart Content ensures snippets are placed exactly where and when you want them — managed safely by the right people.

<h3>Usage</h3>
<p>Administrators have access to both Raw and Safe modes. Trusted non-administrators can be granted access to pre-created blocks in Safe mode by assigning the ‘wpsc_admin’ capability to their role, either through a role editor plugin or via custom code.</p>
<h3>Creating Blocks in WordPress Admin (From the plugin dashboard)</h3>
<ol>
<li>Install and activate WP Smart Content from the WordPress Plugins screen.  </li>
<li>Go to WP Smart Content <span aria-hidden="true" class="wp-exclude-emoji">→</span> Add New Block in the admin menu.  </li>
<li>Enter a descriptive block name.  </li>
<li>Paste your HTML, CSS, or JavaScript into the respective tabs of the block editor.  </li>
<li>Select the desired mode: Raw Mode (unfiltered output) or Safe Mode (sanitized injection).  </li>
<li>Choose where to inject the block, such as:
<ul>
<li>Header (wp_head) for scripts or tracking code  </li>
<li>Footer (wp_footer) for notices or widgets  </li>
<li>Before/after post content for banners or messages  </li>
<li>Block Hooks (WordPress 6.8+) for precise placement in the block editor  </li>
<li>Other classic hooks such as wp_print_scripts or wp_meta  </li>
</ul>
</li>
<li>Configure targeting options:
<ul>
<li>Apply globally (All) or across specific site sections (Frontend, All Posts, All Pages, Backend, Authentication, System Pages) using Target Scopes  </li>
<li>Restrict visibility to selected posts or pages  </li>
</ul>
</li>
<li>Set priority to control execution order when multiple blocks use the same hook.  </li>
<li>Define scheduling by assigning start and end dates so snippets appear only when needed.  </li>
<li>Configure geotargeting to display blocks based on inclusion or exclusion of selected countries.  </li>
<li>Enable revision saving by checking the “Save to revisions” option.  </li>
<li>Publish the block.  </li>
<li>Result: Your scripts, styles, or HTML are injected as configured. Blocks can be managed from the block listing — edit, enable/disable, publish/unpublish, or delete anytime.</li>
</ol>
<h3>Using the Block Editor to Insert Blocks (Placing directly into templates)</h3>
<ol>
<li>Once WP Smart Content is activated, open the Site Editor (Appearance <span aria-hidden="true" class="wp-exclude-emoji">→</span> Editor) for your block theme.  </li>
<li>Locate Block Hook areas (header, footer, before/after post content, sidebar).  </li>
<li>From the block inserter (+), add the “WP Smart Content” block or select an existing block to edit its injection hook.  </li>
<li>Use WP Smart Content settings in the right sidebar (Block tab) to select an injection hook. This links your stored block snippet to the chosen hook.  </li>
<li>Save the template. Your snippet will be injected automatically at the chosen location.  </li>
<li>Result: Scripts, styles, or HTML from the block editor are added via the Block UI without editing theme files, fully compatible with block themes.</li>
</ol>
<h3>Using Shortcodes to Insert Blocks (Place inline within posts, pages, or widgets)</h3>
<ol>
<li>Place the shortcode directly in your post, page, or widget: <code>[wp_smart_content name="blockname"]</code>  </li>
<li>Replace “blockname” with the name of your Smart Content block.  </li>
<li>Result: Scripts, styles, or HTML from the block editor are added at the exact position where the shortcode is placed, respecting publish status, scheduling, and geotargeting.  </li>
<li>Example:<br />
   [wp_smart_content name=”header-banner”]<br />
<span aria-hidden="true" class="wp-exclude-emoji">→</span> This will display the “Header Banner” block inline inside your post or page content.</li>
</ol>
<h3>Geotargeting Setup Notes</h3>
<p>WP Smart Content provides geotargeting support using two options:</p>
<ol>
<li>
<p>Default (Country.is API)</p>
<ul>
<li>No setup required.  </li>
<li>Uses the free Country.is API to detect visitor country by IP. </li>
<li>Ideal for lightweight use cases such as banners, compliance notices, or regional campaigns.  </li>
</ul>
</li>
<li>
<p>Fallback / Advanced (MaxMind GeoLite2 Database)</p>
<ul>
<li>For users who prefer to store IP data locally.  </li>
<li>Requires the GeoLite2 Country database (MMDB format) created and licensed by MaxMind.  </li>
<li>Due to licensing restrictions, the database cannot be redistributed within this plugin.  </li>
<li>Users must download and update the database directly from MaxMind.  </li>
</ul>
</li>
</ol>
<p>Steps to enable MaxMind fallback:</p>
<ol>
<li>Create a free account at https://www.maxmind.com.  </li>
<li>Download the GeoLite2 Country database (MMDB format).  </li>
<li>After downloading the GeoLite2 Country database (GeoLite2-Country.mmdb), place the file here:<br />
   /wp-content/plugins/wp-smart-content/maxmind-db-reader/data/GeoLite2-Country.mmdb </li>
<li>Update the database regularly as required (MaxMind releases monthly updates).  </li>
</ol>
<p>Result:<br />
– By default, WP Smart Content uses Country.is for geotargeting.<br />
– If the MaxMind database is present at the path above, the plugin will use it instead, allowing local IP lookups and more control over data storage.<br />
– If both methods fail, WP Smart Content defaults to rendering content to avoid breaking site functionality.</p>
