Upload SVG images to the media library – safely. Every file is cleaned, gets its real size, and can be shown inline so it can be styled with CSS.

== Description ==

In the WordPress admin the plugin is shown as "DT-svg-support" in the DT-addons menu (Datoden's menu).

WordPress does not allow SVG files, because an SVG file can contain code. DT-svg-support allows them for the roles you choose and cleans every file before it is saved.

* Cleaning: only known SVG elements are kept. Scripts, events (onclick …), javascript: links, <foreignObject> (hidden HTML), external resources, animations that change links and harmful CSS are removed. Entities (XXE attacks) are stopped, and nothing is fetched from outside while the file is read.
* Optional: make the files smaller (comments and editor data from Illustrator, Inkscape, Figma … removed).
* Compressed SVG (.svgz) is unpacked to .svg.
* Real width and height, read from the file (width/height or viewBox): <img> gets width and height (no layout shift), wp_get_attachment_image(), featured images and custom logos work, and the media library shows previews. Older SVG files without a size get it automatically.
* Inline SVG: images with a class (style-svg as standard – the same as in SVG Support) or all SVG images are replaced by their code on the page, so they can be colored and animated with CSS. Done on the server, without JavaScript, for the whole page. Repeated SVGs get unique ids. The alt text becomes aria-label. The class no-inline leaves an image as it is.
* Shortcode [datoden_svg id="123" size="48" label="…"]: shows an SVG image from the media library at the given width, with the height in proportion.
* Check the existing SVG files: older files get their size, and files with content that should not be there can be cleaned (the original is kept in wp-content/uploads/dt-svg-backup/).
* Move from SVG Support with one click: its settings are taken over and it is turned off.

= Pro add-on =

In the separate paid add-on Datoden SVG Support Pro (from Datoden, not part of this plugin): inline per image, or with the color following the text (also in dark mode); the SVG icon block with size and color in the editor and color in the [datoden_svg] shortcode; and a cleaning log.

= Free Datoden account (optional) =

Everything in the plugin works without an account. A free Datoden account adds DT-website-guard, an overview of all your websites and settings profiles you can use on other websites.

== Frequently Asked Questions ==

= Does the cleaning change how the image looks? =

No. Only things that can run code or fetch something from another website are removed.

= How do I color an inline SVG with CSS? =

For example: .dt-svg-inline path { fill: currentColor; } – the image then follows the text color.

== External services ==

This plugin can connect to Datoden (https://datoden.com), a service run by Responsit AB, Sweden. The connection is optional – everything in the plugin works without it. Nothing is sent to Datoden until an administrator clicks "Start DT-website-guard" (or "Connect") in the WordPress admin and approves the connection on datoden.se or datoden.com. You can disconnect at any time with "Disconnect" (or by turning DT-website-guard off) on the DT-website-guard page; then nothing more is sent.

What is sent to Datoden, and when (only while the website is connected, except the connection itself):

* When you connect: the website address, the administrator's language (Swedish or English), the WordPress address that Datoden returns to and a random check value. After you approve on Datoden, the website sends the one-time code it got back, together with the website address and the language, and receives a website key that is stored in your database.
* Once a day (WordPress cron), and when an administrator opens a DT plugin page and the last contact is more than six hours old: the website key, the language, and the folder names, versions and active state of the installed Datoden plugins (for example datoden-cookie-consent). The answer can contain short messages from Datoden and updated wording for the DT plugins' texts, which are shown on the plugins' pages.
* When an administrator opens the DT-website-guard page or a DT plugin page (at most every five minutes), or clicks "Check again": the website key, to get the latest result of Datoden's monitoring (up or down, response time, and the expiry dates of the SSL certificate and the domain). "Check again" also asks Datoden to check the website once more.
* When the DT-website-guard page is shown and the DT-website-guard plugin is installed: the list of Datoden's plugins and their versions is fetched from datoden.se, at most every six hours. No data about the website is sent.
* When you click "My websites": the website key, the language and the email address of the logged-in WordPress user, so that Datoden can sign you in directly if it is the same address as your Datoden account.
* When you save, use or delete a settings profile: the website key, and when saving the settings of DT-cookie and DT-darkmode (no personal data; website-specific values such as the logo and the privacy page are left out). They are stored in or read from your Datoden account.
* When you disconnect: the website key, so that Datoden can remove it.
* While connected, Datoden visits the public website every five minutes (like any visitor) to check that it is up, reads its SSL certificate and looks up the domain's public registration data to find when it expires. The plugin shows the dates as Datoden reports them; the website does not contact any other service for this.

== Source code ==

Everything in this plugin is the original, human-readable source code. The PHP, JavaScript and CSS files are written by hand and are neither minified nor generated by a build tool, so there is no build step: the files in the plugin folder are the source and can be read and edited directly.

== Changelog ==

= 3.0.8 =
Core 3.0.8: the return from Datoden (Connect) is also checked with a WordPress nonce (WordPress.org review); the readme describes the source code.

= 3.0.7 =
Datoden-core 3.0.7: the plugins' settings are checked with a single database query when the page loads – missing or non-autoloaded settings used to cost one query each on every page.

= 3.0.6 =
* Review fixes in all plugins: prefixed JavaScript names, the WordPress 6.9 template enhancement output buffer (older WordPress: the buffer is closed explicitly), cache paths from content_url(). Dark Mode: block theme palettes are converted per use. SVG Support: steps back while the SVG Support plugin is active. Code Snippets: the WPCode switch button is shown for all imported snippets.

= 3.0.5 =
* Datoden-core 3.0.5: the plugin icon shows its symbol at full size, cut by the corner with the Datoden logo.

= 3.0.4 =
* Datoden-core 3.0.4: plugin icons without the white background – the cut corner is transparent and the Datoden logo uses the icon's light colour.

= 3.0.3 =
* Datoden-core 3.0.3: new plugin icon design – a cut white corner with the Datoden logo.

= 3.0.2 =
* Datoden-core 3.0.2: the plugin's own icon (the same as on WordPress.org) is shown in the DT-addons overview and in the header of the plugin's page.

= 3.0.1 =
* Datoden-core 3.0.1: the header on the plugin's page shows the plugin's name as on WordPress.org.

= 3.0.0 =
* New name on WordPress.org: Datoden SVG Support (shown as DT-svg-support in the DT-addons menu). The free plugin contains no locked Pro features – they are only in the separate Datoden SVG Support Pro. Websites with the earlier version are moved to the new folder automatically; settings are kept.

= 2.0.1 =
* Plugin Check: redirects to Datoden use wp_safe_redirect, and the descriptions on the Datoden plugins overview are translated with WordPress' own function. Datoden-core 2.0.1.

= 2.0.0 =
* New prefix datoden_ instead of dt_ (WordPress.org). Settings and data are moved automatically on the first load; the old [dt_…] shortcodes, hooks and REST routes keep working. Works together with older DT plugins until they are updated. Datoden-core 2.0.0.

= 1.2.10 =
* Ready for WordPress.org: Plugin Check rules (sanitising, nonces, WordPress file functions), no inline scripts in admin pages, DT-core 1.17.22.

= 1.2.9 =
* DT-core 1.17.21: shared core cleaned up (unused code removed) – the same core in every plugin, no change in behaviour.

= 1.2.8 =
* DT-core 1.17.12: the menu heading is called DT-addons and the overview section Datoden plugins.

= 1.2.7 =
* DT-core 1.17.11: the Pro features require a licence – the website must be connected to Datoden and have a purchased licence or be activated by Datoden. Without a licence the base plugin runs without Pro, with a notice saying why (three days to connect after installing or updating).

= 1.2.6 =
* DT-core 1.17.10: DT-website-guard includes itself in the list sent to Datoden – Control the website, Health and Updates show again in My websites, and DT-website-guard gets its updates from Datoden.

= 1.2.5 =
* DT-core 1.17.9: the menu heading is called Datoden Addons (DT-datoden-addons wrapped onto two lines).

= 1.2.4 =
* DT-core 1.17.8: the menu heading is called DT-datoden-addons (without the Pro badge); the first row in the menu and the overview are still called DT-website-guard.

= 1.2.3 =
* DT-core 1.17.7: the DT-website-guard overview shows every DT plugin – the ones that are not installed with Install (downloaded from Datoden) and Read more; deactivated ones with Activate.

= 1.2.2 =
* DT-addons is now called DT-website-guard (the menu, the overview, the plugins list and the texts in every DT plugin). The folder and the settings stay the same (dt-addons), so updates and everything saved work as before. DT-core 1.17.6.

= 1.2.1 =
* DT-core 1.17.5: the card about what Pro adds is shown at the top of the sidebar (only without Pro) – in every DT plugin.

= 1.2.0 =
* DT-svg-support Pro is available as an add-on (per-image inline and "color follows the text", the SVG icon block and [dt_svg] shortcode, and a cleaning log). The free plugin is unchanged apart from a Pro card on the settings page.
* The cleaner now reports what it removed (for example <script> or onclick).

= 1.1.0 =
* Free and Pro: fully free, also on WordPress.org. DT-core 1.16.0 – the domain expiry is read from rdap.org only when the website is connected or you click Check again; updates from Datoden are Pro-only.

= 1.0.26 =
* DT-core 1.15.1: the header (logo, Datoden badge, buttons, language switch, Saved) and the Made by Datoden line are rendered by the core – the plugin only provides its name, version, description and any tabs. The collapse/expand arrow always sits at the far right of the card.

= 1.0.25 =
* DT-core 1.14.0: the header, the DT-addons menu and everything else shared (dt-hub.php, dt-autosave.js, dt-admin.css and Datoden images) live in the dt-core/ folder. Of all active DT plugins only the newest copy is used – updating one plugin with a newer core gives every plugin the new header, and all pages load the same files (cached once by the browser).

= 1.0.24 =
* Shared header script: in DT-addons, Messages go below Install or update in the sidebar.

= 1.0.23 =
* The tab row sits at the top of the main column – above the main cards only, so the sidebar starts at the top beside it.

= 1.0.22 =
* Tabs (e.g. Languages | Menus in DT-language) are a full-width row right below the header, above the cards – no longer small inside the header, so they are not missed.

= 1.0.21 =
* Every card – also in the main column and the cards above it – collapses and expands with a click on its heading. The arrow sits right after the heading, so switches and buttons on the right stay visible when the card is collapsed.

= 1.0.20 =
* Sidebar cards collapse and expand with a click on their heading – remembered per card. Collapsed Messages shows the count. In DT-addons the Datoden account is at the top of the sidebar (DT-hub 1.13.2).

= 1.0.19 =
* Closed messages stay closed after reloading the page.

= 1.0.18 =
* Messages are shown in the sidebar (Messages card) instead of the header.

= 1.0.17 =
* The first item under DT-addons in the menu is called DT-addons instead of Overview.

= 1.0.16 =
* The Datoden menu is now called DT-addons; the overview has a larger DT-website-guard panel.

= 1.0.15 =
* Undo/Redo tooltips say what will be undone or redone. Undo, Redo and Saved are always in the same place, greyed out when there is nothing to do.

= 1.0.14 =
* Header: subtle dividers between the groups of controls.

= 1.0.13 =
* Undo now works everywhere, also right after a change, for added/removed rows, the form builder and the code editor.

= 1.0.12 =
* Undo / Redo in the header of every DT plugin. The save status keeps its width; other messages are shown on top so nothing moves.

= 1.0.11 =
* Header rearranged: version next to the plugin name, buttons top right, Saved after the language switch, the Datoden logo links to Datoden's apps.

= 1.0.10 =
* The Datoden overview page has the same header as the plugins.

= 1.0.9 =
* Dark mode: the header shows the light Datoden logo (datoden-logo-darkmode.svg).

= 1.0.8 =
* The sidebar toggle moved into the header; when hidden the content uses the full width. The collapsed header shows the Datoden logo.

= 1.0.7 =
* The sidebar now lines up with the content (no extra gap at the top).

= 1.0.6 =
* The sidebar toggle sits in the top right corner with a sidebar icon.

= 1.0.5 =
* Header buttons: keep the header at the top while scrolling (pin) and collapse it so only Saved and the language switch show. The sidebar can be collapsed to a small button. The language switch is greyed out on pages without texts to translate.

= 1.0.4 =
* Shared stylesheet updated, same as the other DT plugins.

= 1.0.3 =
* The plugin header now stays at the top when you scroll. Saved status and the SV | EN language switch moved from the admin bar into the header, below the badges.

= 1.0.2 =
* Unified names: the plugin is now called DT-svg-support - datoden (lowercase after DT, like all DT plugins). The folder, settings and shortcodes are unchanged.

= 1.0.1 =
* Fix: the "Move from SVG Support" box stayed after the move.

= 1.0.0 =
* First version: SVG uploads per role, cleaning, real sizes, media library previews, inline SVG on the server, checking and cleaning existing files, and moving from SVG Support.

== Upgrade Notice ==

= 2.0.0 =
Install all DT plugins together; settings are moved automatically.
