Using WordPress ‘dashboard_browser_nag_class()’ PHP function

by

The dashboard_browser_nag_class() WordPress PHP function adds an additional class to the browser nag if the current version is insecure.

Usage

Here’s a general way to use the function:

$classes = array("my-class1", "my-class2");
$classes = dashboard_browser_nag_class($classes);

In this example, the function is called with a custom array of classes named “my-class1” and “my-class2”. The function checks the current browser version and if it is insecure, it adds an extra class to the array.

Parameters

  • $classes (array) – This is a required parameter. It is an array of meta box classes.

Examples

Basic Usage

This demonstrates how to use the function with an array of classes:

$classes = array("class1", "class2");
$classes = dashboard_browser_nag_class($classes);

// The $classes array now might have an additional class if the browser version is insecure.

Checking the Added Class

This example checks if the insecure browser class was added:

$classes = array("class1", "class2");
$classes = dashboard_browser_nag_class($classes);

if (in_array("insecure-browser", $classes)) {
    echo "Insecure browser detected!";
}

Adding More Classes

Here, we are adding more classes to the array:

$classes = array("class1", "class2", "class3");
$classes = dashboard_browser_nag_class($classes);

Using With Empty Array

Even if we start with an empty array, the function still works:

$classes = array();
$classes = dashboard_browser_nag_class($classes);

Counting the Number of Classes

This example counts the number of classes in the array after the function call:

$classes = array("class1", "class2");
$classes = dashboard_browser_nag_class($classes);

echo count($classes);

In this case, the count will be 2 if the browser is secure, and 3 if it is insecure.
