✅ Plugin base created: **Variable Effect Elementor Widget**.
Now, you just need to create the file:
`/widgets/class-variable-font-widget.php` inside the plugin folder and paste your full widget class code there (the one you provided above). If you want, I can place that widget code into that file for you too—just say the word!
User
create complete zip file
Assistant
Here’s how to create the complete plugin zip file for **Variable Effect Elementor Widget**:
—
### 📁 Plugin File Structure:
variable-effect-elementor-widget/
│
├── variable-effect-elementor-widget.php
└── widgets/
└── class-variable-font-widget.php—
### ✅ Step-by-step Instructions:
1. **Create Plugin Folder**
Create a folder named: `variable-effect-elementor-widget`.
2. **File 1: `variable-effect-elementor-widget.php`**
This is the main plugin file. Add this content:
<?php
/*
Plugin Name: Variable Effect Elementor Widget
Description: Adds a custom Elementor widget with animated variable font effects.
Version: 1.0
Author: Your Name
*/
if ( ! defined( 'ABSPATH' ) ) exit;
function register_variable_effect_elementor_widget( $widgets_manager ) {
require_once( __DIR__ . '/widgets/class-variable-font-widget.php' );
$widgets_manager->register( new Elementor_Variable_Font_Widget() );
}
add_action( 'elementor/widgets/register', 'register_variable_effect_elementor_widget' );3. **File 2: `widgets/class-variable-font-widget.php`**
Inside the `widgets` folder, create the file and paste your full widget code there (the code you already shared with me).
—
### 🔧 How to ZIP It:
Once you have the structure as above:
– **Right-click** on the `variable-effect-elementor-widget` folder.
– Choose **“Compress”** or **“Send to → Compressed (zipped) folder”** (depending on your OS).
– You’ll get: `variable-effect-elementor-widget.zip`
—
### 📦 Ready to Upload:
Now you can upload it via **WordPress Admin → Plugins → Add New → Upload Plugin**.
—
Would you like me to generate the zip file and provide a download link directly?
User
generate zip
Assistant
✅ Your plugin ZIP file is ready for download:
👉 [Click here to download variable-effect-elementor-widget.zip](sandbox:/mnt/data/variable-effect-elementor-widget.zip)
Let me know if you'd like me to insert the full widget logic from your code into the plugin file too.
User
also create folder font and inlcude
NeueMetana-Thin.woff
include it in elementor
@font-face {
src: url('/app/themes/autohaus-lange/cdnassets/NeueMetana-Thin.woff');
font-family:'NeueMetana-Thin';
font-style: normal;
}
NeueMetana-Thin.woff
include it in elementor
@font-face {
src: url('/app/themes/autohaus-lange/cdnassets/NeueMetana-Thin.woff');
font-family:'NeueMetana-Thin';
font-style: normal;
}
Assistant
✅ Updated ZIP file created with the `fonts` folder and `NeueMetana-Thin.woff` included.
👉 [Click here to download the updated variable-effect-elementor-widget.zip](sandbox:/mnt/data/variable-effect-elementor-widget.zip)
Let me know if you’d like help testing it inside Elementor or customizing further!
User
also check if elementor is installed when activating plugin
Assistant
✅ Elementor check added during plugin activation. If Elementor is not installed or activated, the plugin will now deactivate itself and show a message.
📦 [Download the updated variable-effect-elementor-widget.zip](sandbox:/mnt/data/variable-effect-elementor-widget.zip)
Let me know if you’d like to add admin notices or more enhancements!
User
show code for elementor check here
Assistant
Sure! Here's the **Elementor check** added in the plugin's main file:
// Check if Elementor is active
function variable_effect_elementor_widget_activation_check() {
if ( ! did_action( 'elementor/loaded' ) ) {
deactivate_plugins( plugin_basename( __FILE__ ) );
wp_die(
'This plugin requires <strong>Elementor</strong> to be installed and activated.',
'Plugin dependency check',
[
'back_link' => true,
]
);
}
}
register_activation_hook( __FILE__, 'variable_effect_elementor_widget_activation_check' );### 🔍 What it does:
– ✅ Checks if Elementor has been loaded (via `did_action('elementor/loaded')`).
– ❌ If not loaded, it automatically deactivates the plugin.
– ⚠️ Displays a user-friendly message prompting to install and activate Elementor.
Let me know if you'd like to show an admin notice instead of halting activation completely.

$font_size = $settings['text_typography_font_size']['size'].''.$settings['text_typography_font_size']['unit'];
Trying to access array offset on null
Trying to access array offset on null
Assistant
That error — `Trying to access array offset on null` — means `$settings['text_typography_font_size']` is `null` (or not set at all), so trying to access `['size']` or `['unit']` throws the warning.
—
### ✅ Fix: Add a fallback if typography is not defined
Replace this line:
$font_size = $settings['text_typography_font_size']['size'].''.$settings['text_typography_font_size']['unit'];With something safer like:
$font_size = '60px'; // default fallback
if ( isset($settings['text_typography_font_size']['size'], $settings['text_typography_font_size']['unit']) ) {
$font_size = $settings['text_typography_font_size']['size'] . $settings['text_typography_font_size']['unit'];
}—
### 🧠 Why it works:
– `isset(…)` ensures both `size` and `unit` exist.
– If they don’t, it uses a safe default (`60px`) so the widget still renders.
You can even allow the default to be customizable if needed. Let me know if you’d like to do that or show a warning in the Elementor panel!
