Viewhelper:

IpViewHelper

ViewHelper to determine and output the client IP address.
This ViewHelper checks in the following order:

1. HTTP_CLIENT_IP (shared internet)
2. HTTP_X_FORWARDED_FOR (proxy)
3. REMOTE_ADDR (direct connection)

Example usage:

<!-- Output the client IP address -->
<gfv:ip />
{gfv:ip()}

<!-- Compare against a specific IP -->
<f:if condition="{gfv:ip()} == '200.200.200.200'">
    <!-- content shown only for this IP -->
</f:if>

Returns an empty string when no valid IP address can be determined (e.g. CLI context).

Namespace cloudflare:
{gfv:cloudflare}

StreamIframeViewHelper

Generates an iframe tag to embed a Cloudflare Stream video.
Constructs the iframe src URL by concatenating:

• streamid:
  Cloudflare Stream video ID
• customerid:
  Cloudflare customer/account ID

Optional parameters:

• preload:
  Video preload mode
  Default:'none'
• loop:
  Loop video after end
  Default:false
• muted:
  Start muted
  Default:false
• autoplay:
  Autoplay video
  Default:null
• poster:
  Poster timestamp in seconds
  Default:null

Example usage:

<gfv:streamIframe streamid="abc123" customerid="42" preload="auto" loop="true" muted="false" autoplay="true" />

Namespace resource:
{gfv:resource}

SvgInlineViewHelper

Renders an SVG file inline by embedding its XML content directly into the output.
It handles loading the file via FAL (File or FileReference) or by path, validates that the file is non-empty and an SVG, then parses and injects attributes safely.
Pass additional data-attributes or arbitrary attributes via `data` and `additionalAttributes` arguments.

Example usage:

<gfv:resource.svgInline src="EXT:Sitepackage/Resources/Public/Logo.svg" width="200" />

or

<gfv:resource.svgInline image="{fileReference}" class="icon" id="logo" viewBox="0 0 100 100" />

Namespace link:
{gfv:link}

TelViewHelper — link.tel

Renders an <a href="[scheme]+..."> link for a phone number.
The number is normalized to E.164 format. The original formatted number is used as link text unless child content is provided.

• number:
  Phone number in international format (must start with +)

Optional parameters:

• scheme:
  URI scheme to prepend. Allowed: tel:, fax:, sms:, callto:
  Default: tel:
• class, id, title, etc.:
  All standard HTML tag attributes are supported.

Example usage:

<gfv:link.tel number="[phone]" />
<gfv:link.tel number="[phone]" scheme="fax:" />
<gfv:link.tel number="[phone]">Call us</gfv:link.tel>
{gfv:link.tel(number: '[phone]')}

Namespace uri:
{gfv:uri}

TelViewHelper — uri.tel

Returns a tel: URI string for a phone number without rendering an HTML tag.
Use this when you need the href value only, e.g. to pass it to another ViewHelper.

• number:
  Phone number in international format (must start with +)

Example usage:

{gfv:uri.tel(number: '[phone]')}
<a href="{gfv:uri.tel(number: phoneNumber)}">Call</a>

Namespace composer:
{gfv:composer}

PackageInfoViewHelper

This ViewHelper exposes package metadata as reported by Composer\InstalledVersions

• name:
  Composer package name ("vendor/package") or ext key if heuristicResolve=1.

Optional parameters:

• key:
  Optional key to return: packageName|isInstalled|version|prettyVersion|reference|installPath.
  Default:''
• jsonEncode:
  Return JSON-encoded result (useful for arrays).
  Default:false
• heuristicResolve:
  Resolve ext key to package by suffix match if no slash is present.
  Default:true
• exposeInstallPath:
  Include absolute install path (can be sensitive).
  Default:false

Example usage:

<gf:composer.packageInfo name="vendor/package" key="prettyVersion" />
