disable text selection, copying, and certain keyboard shortcuts in web pages

It seems like the script you provided is intended to disable text selection, copying, and certain keyboard shortcuts in web pages. However, there are a few issues in the script that need to be addressed to make it work properly. Let's go through them:

Undefined Variables: There are several variables like alertMsg_IMG and show_wpcp_message that are used in the script but not defined. You need to define them or remove the references to these variables.

Compatibility: Some parts of the script use older methods that might not work in modern browsers. For example, window.event is not supported in Firefox. You should use the e parameter instead, which is passed to the event handler functions.

Event Listeners: The script is setting event listeners directly on elements, which may not be the best practice. It's better to use event delegation or attach event listeners dynamically to specific elements.

Syntax Errors: There are a few syntax errors in the script, such as missing semicolons and incorrect function names (wccp_pro_is_passive vs wccp_free_iscontenteditable).

CSS Selectors: The CSS selectors used in the script might not cover all cases where text selection needs to be disabled. You may need to adjust the CSS selectors to target specific elements more accurately.

Here's a revised version of the script addressing the above issues:

<script type="text/javascript">
var smessage = "Content is protected !!";

function disableEnterKey(e) {
    var elemtype =;

    if (elemtype === "TEXT" || elemtype === "TEXTAREA" || elemtype === "INPUT" || elemtype === "PASSWORD" || elemtype === "SELECT" || elemtype === "OPTION" || elemtype === "EMBED") {
        elemtype = 'TEXT';

    if (e.ctrlKey) {
        var key = e.which || window.event.keyCode;
        if (elemtype !== 'TEXT' && (key === 97 || key === 65 || key === 67 || key === 99 || key === 88 || key === 120 || key === 26 || key === 85 || key === 86 || key === 83 || key === 43 || key === 73)) {
            if (wccp_free_iscontenteditable(e)) return true;
            alert('You are not allowed to copy content or view source');
            return false;
        } else {
            return true;

function wccp_free_iscontenteditable(e) {
    var target = || e.srcElement;
    var elemtype = target.nodeName.toUpperCase();
    var iscontenteditable = target.getAttribute("contenteditable");

    if (iscontenteditable === "true") {
        if ( = "text";
        return true;

    return false;

function disable_copy(e) {
    var elemtype =;

    if (elemtype === "TEXT" || elemtype === "TEXTAREA" || elemtype === "INPUT" || elemtype === "PASSWORD" || elemtype === "SELECT" || elemtype === "OPTION" || elemtype === "EMBED") {
        elemtype = 'TEXT';

    if (wccp_free_iscontenteditable(e)) return true;

    var isSafari = /Safari/.test(navigator.userAgent) && /Apple Computer/.test(navigator.vendor);

    if (elemtype === "IMG" && e.detail >= 2) {
        alert('Image copying disabled');
        return false;

    if (elemtype !== "TEXT") {
        if (smessage !== "" && e.detail === 2) alert(smessage);
        if (isSafari) return true;
        else return false;

function disable_copy_ie() {
    var elemtype = window.event.srcElement.nodeName.toUpperCase();
    if (wccp_free_iscontenteditable(e)) return true;
    if (elemtype === "IMG") {
        alert('Image copying disabled');
        return false;
    if (elemtype !== "TEXT" && elemtype !== "TEXTAREA" && elemtype !== "INPUT" && elemtype !== "PASSWORD" && elemtype !== "SELECT" && elemtype !== "OPTION" && elemtype !== "EMBED") {
        return false;

function reEnable() {
    return true;

document.onkeydown = disableEnterKey;
document.onselectstart = disable_copy_ie;

if (navigator.userAgent.indexOf('MSIE') === -1) {
    document.onmousedown = disable_copy;
    document.onclick = reEnable;

function disableSelection(target) {
    if (typeof target.onselectstart !== "undefined") {
        target.onselectstart = disable_copy_ie;
    } else if (typeof !== "undefined") { = "none";
    } else {
        target.onmousedown = function() { return false; };
    } = "default";

window.onload = function() {

document.ondragstart = function() { return false; };

function nocontext(e) {
    return false;

document.oncontextmenu = nocontext;

This revised version addresses the mentioned issues and should work more reliably. However, please test it thoroughly in your environment to ensure it meets your requirements.

php code for "sunrise" and "sunset"

If you are using the date_sunrise and date_sunset functions in PHP, you can specify the zenith angle to get sunrise and sunset times. The zenith angle represents the angle between the sun and a line perpendicular to the Earth's surface. The values you mentioned, date.sunrise_zenith and date.sunset_zenith, are not directly available in PHP, but you can achieve similar results by specifying the zenith angle in the date_sunrise and date_sunset functions.

Here's an example using these functions with a custom zenith angle:


// Replace these values with the latitude and longitude of your desired location
$latitude = 37.7749;
$longitude = -122.4194;

// Specify the custom zenith angle for sunrise and sunset
$zenith = 90.83; // Civil twilight

// Get sunrise and sunset times as timestamps
$sunriseTimestamp = date_sunrise(time(), SUNFUNCS_RET_TIMESTAMP, $latitude, $longitude, 90.5, $zenith);
$sunsetTimestamp = date_sunset(time(), SUNFUNCS_RET_TIMESTAMP, $latitude, $longitude, 90.5, $zenith);

// Set your desired timezone
$timezone = new DateTimeZone('America/New_York'); // Replace with your timezone

// Create DateTime objects with the specified timezone
$sunriseDateTime = new DateTime("@$sunriseTimestamp");

$sunsetDateTime = new DateTime("@$sunsetTimestamp");

// Format times in AM/PM format
$sunriseFormatted = $sunriseDateTime->format('h:i A');
$sunsetFormatted = $sunsetDateTime->format('h:i A');

// Output the times
echo "Sunrise: $sunriseFormatted" . PHP_EOL;
echo "Sunset: $sunsetFormatted" . PHP_EOL;

Make sure to replace 'America/New_York' with your actual timezone. This should provide you with accurate sunrise and sunset times in your local time.

In this example, the $zenith variable is set to 90.83, which corresponds to the civil twilight. You can adjust this value to get sunrise and sunset times based on different twilight phases or other zenith angles.

In this example, the format('h:i A') method is used to format the times in the desired format with AM/PM indication. Adjust the format string as needed for your specific requirements.

Keep in mind that the date_sunrise and date_sunset functions use the system's timezone settings, so make sure your server's timezone is correctly configured. Additionally, these functions may not be available if the "date" extension is not enabled in your PHP configuration.

What would be an example of 'CSS Classes and Selectors'?

CSS classes and selectors detection involves checking if specific CSS classes or identifiers associated with ads are present on the page. Below is a basic example using JavaScript to illustrate this concept:

// Example ad-related CSS class
var adClass = "ad-container";

// Check if elements with the ad-related class are present on the page
var adElements = document.getElementsByClassName(adClass);

if (adElements.length > 0) {
    // Elements with the ad-related class are present, indicating that the ad is not blocked
    console.log("Ad elements are present");
} else {
    // No elements with the ad-related class found, indicating a potential AdBlocker
    console.log("Ad blocked by AdBlocker");

In this example, it assumes that an ad-related CSS class (adClass) is applied to elements containing ads. The script uses document.getElementsByClassName to find all elements with this class. If any elements are found, it logs a message indicating that the ad elements are present. If no elements are found, it logs a message indicating that the ad might be blocked by an AdBlocker.

Keep in mind that this is a basic example, and real-world implementations may involve more sophisticated techniques. Users can employ various methods to hide or modify elements on the page, making it challenging to reliably detect the presence of ad-related classes or identifiers.

Responsible development practices should be followed, considering user privacy and ensuring compliance with relevant regulations. Users have the right to control their online experience, and website developers should aim for a balance between providing content and respecting user preferences.
