Wordpress - hide div with class in admin interface - wordpress

I tried this code which should hide the div with class .my_class for all users except admin, however I still see the div as a normal user.
function hide_form_result_buttons() {
if (!current_user_can('manage_options') && !is_admin()) {
echo '\<style type="text/css"\> .my_class { display: none !important; } \</style\>';
}
}
add_action('wp_head', 'hide_form_result_buttons');
add_action('admin_head', 'hide_form_result_buttons');

This code function :)
function hide_form_result_buttons() {
if (!current_user_can('manage_options')) {
?>
<script type="text/javascript">
document.addEventListener("DOMContentLoaded", function(event) {
var formResultButtons = document.querySelectorAll(".form-result-buttons");
for (var i = 0; i < formResultButtons.length; i++) {
formResultButtons[i].style.display = "none";
}
});
</script>
<?php
}
}
add_action('wp_head', 'hide_form_result_buttons');
add_action('admin_head', 'hide_form_result_buttons');

Save dark mode in php cookies

I worked on a simple little code for black mode
I would just like to store the theme for the user in cookies for x time
My Dark Theme in css :
body {
padding: 0px;
color: black;
font-size: 25px;
background-color: white;
}
.dark-mode .mainSection {
background-color: black;
color: white;
padding: 600px;
padding-top: 470px;
}
Html
<div id="dark-mode">
<li><font size="2">
<a class="nav-link" onclick="myFunction()">Dark Mode</font
</li>
</div>
Javascript :
function myFunction() {
var element = document.body;
element.classList.toggle("dark-mode");
}
Thank you
Simply set the cookie using javascript, and the next time the client makes the request to server, the cookies will be send along with it. The below code should work
function createCookie(name, value, timeInSeconds) {
var date = new Date();
date.setTime(date.getTime()+(timeInSeconds*1000));
var expires = "; expires="+date.toGMTString();
document.cookie = name+"="+value+expires+"; path=/";
}
function getCookie(cname) {
let name = cname + "=";
let decodedCookie = decodeURIComponent(document.cookie);
let ca = decodedCookie.split(';');
for(let i = 0; i <ca.length; i++) {
let c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
function myFunction() {
var element = document.body;
const isDarkModeOn = element.classList.toggle("dark-mode");
createCookie("isDarkModeOn", isDarkMode.toString(), 60 * 60 * 24); // 1 day expiry date
}
window.onload = function () {
const isDarkModeOn = getCookie("isDarkModeOn");
if(isDarkModeOn === "true") document.body.classList.add("dark-mode");
}
After that simply check the cookie in PHP,
<?php
$isDarkModeOn = $_COOKIE["isDarkModeOn"] === "true";
if($isDarkModeOn) {
echo "Dark Mode is on";
}
?>

WordPress Plugin Hook filter body_class

I want to achieve that when the page attribute selects a certain template, the background color of the page can be randomly changed. (Only this page, not for all pages).
Unfortunately, my code (PHP) doesn't work.
add_filter( 'body_class','modele_bg_couleur' );
function modele_bg_couleur($classes)
{
if(is_page_template('modele-bg-couleur.php')){
$test = array("beige", "azure", "linen", "snow");
$classes[] = $test[array_rand($test)];
}
return $classes;
}
add_action( 'admin_head', 'modele_bg_couleur_css' );
function modele_bg_couleur_css(){
echo "
<style type='text/css'>
.beige {
background-color: beige;
}
.azure {
background-color: azure;
}
.linen {
background-color: linen;
}
.snow {
background-color: snow;
}
</style>
";
}
The body_class filter lets you add classes to the front end of your site. The admin_head action lets you add custom code to the admin pages (Wordpress back end). So right now you are adding a body class to the front end of your site but applying the CSS to the back end.
I'm assuming you want this to work on your front end. You can then just add the following CSS to your theme via the customizer or via your own child theme:
body.beige { background-color: beige!important; }
body.azure { background-color: azure!important; }
body.linen { background-color: linen!important; }
body.snow { background-color: snow!important; }

How to display block or trigger the style on Woocommerce if !is_in_stock

I am trying to display a block or DIV when the product is out of stock but the condition does not appear to work
add_action( 'woocommerce_get_availability', 'display_welcome', 10);
function display_welcome() {
global $_product;
if ( ! $_product->is_in_stock() ) {
?>
<style>
#hello {display:block }

Sticky scrollbar at bottom of table

I'm not sure if "sticky" is the term for this, but is there a way to make the scrollbar from overflow:auto stay visible?
I have a rather large table that I want to be scrollable horizontally; however, the table is fairly tall as well, so when the page loads the horizontal scrollbar is not within the viewport of the browser, so it's rather hard to tell that the table is scrollable at all.
<div style = 'width:900px;overflow:auto'>
<table>
<!-- Very large table here -->
</table>
</div>
The scroll bar appears below the table, but unfortunately the table is so tall you can't see it unless you scroll down.
I'd like to have the horizontal scrollbar stay visible even if the table goes off the screen, maybe fixed to the bottom of the viewport. Ideally I'd like to do it using only CSS or a minimal amount of javascript.
Here is a script for that http://jsfiddle.net/TBnqw/2288/
$(function($){
var scrollbar = $('<div id="fixed-scrollbar"><div></div></div>').appendTo($(document.body));
scrollbar.hide().css({
overflowX:'auto',
position:'fixed',
width:'100%',
bottom:0
});
var fakecontent = scrollbar.find('div');
function top(e) {
return e.offset().top;
}
function bottom(e) {
return e.offset().top + e.height();
}
var active = $([]);
function find_active() {
scrollbar.show();
var active = $([]);
$('.fixed-scrollbar').each(function() {
if (top($(this)) < top(scrollbar) && bottom($(this)) > bottom(scrollbar)) {
fakecontent.width($(this).get(0).scrollWidth);
fakecontent.height(1);
active = $(this);
}
});
fit(active);
return active;
}
function fit(active) {
if (!active.length) return scrollbar.hide();
scrollbar.css({left: active.offset().left, width:active.width()});
fakecontent.width($(this).get(0).scrollWidth);
fakecontent.height(1);
delete lastScroll;
}
function onscroll(){
var oldactive = active;
active = find_active();
if (oldactive.not(active).length) {
oldactive.unbind('scroll', update);
}
if (active.not(oldactive).length) {
active.scroll(update);
}
update();
}
var lastScroll;
function scroll() {
if (!active.length) return;
if (scrollbar.scrollLeft() === lastScroll) return;
lastScroll = scrollbar.scrollLeft();
active.scrollLeft(lastScroll);
}
function update() {
if (!active.length) return;
if (active.scrollLeft() === lastScroll) return;
lastScroll = active.scrollLeft();
scrollbar.scrollLeft(lastScroll);
}
scrollbar.scroll(scroll);
onscroll();
$(window).scroll(onscroll);
$(window).resize(onscroll);
});
It is a quick test rather than a complete generic plugin, but is a good start, I think
Here's my take, #user2451227's is almost perfect, but didn't work with nested overflowed elements and had a number of performance issues, so I rewrote it:
$(function($){
var fixedBarTemplate = '<div class="fixed-scrollbar"><div></div></div>';
var fixedBarCSS = { display: 'none', overflowX: 'scroll', position: 'fixed', width: '100%', bottom: 0 };
$('.fixed-scrollbar-container').each(function() {
var $container = $(this);
var $bar = $(fixedBarTemplate).appendTo($container).css(fixedBarCSS);
$bar.scroll(function() {
$container.scrollLeft($bar.scrollLeft());
});
$bar.data("status", "off");
});
var fixSize = function() {
$('.fixed-scrollbar').each(function() {
var $bar = $(this);
var $container = $bar.parent();
$bar.children('div').height(1).width($container[0].scrollWidth);
$bar.width($container.width()).scrollLeft($container.scrollLeft());
});
$(window).trigger("scroll.fixedbar");
};
$(window).on("load.fixedbar resize.fixedbar", function() {
fixSize();
});
var scrollTimeout = null;
$(window).on("scroll.fixedbar", function() {
clearTimeout(scrollTimeout);
scrollTimeout = setTimeout(function() {
$('.fixed-scrollbar-container').each(function() {
var $container = $(this);
var $bar = $container.children('.fixed-scrollbar');
if($bar.length && ($container[0].scrollWidth > $container.width())) {
var containerOffset = {top: $container.offset().top, bottom: $container.offset().top + $container.height() };
var windowOffset = {top: $(window).scrollTop(), bottom: $(window).scrollTop() + $(window).height() };
if((containerOffset.top > windowOffset.bottom) || (windowOffset.bottom > containerOffset.bottom)) {
if($bar.data("status") == "on") {
$bar.hide().data("status", "off");
}
} else {
if($bar.data("status") == "off") {
$bar.show().data("status", "on");
$bar.scrollLeft($container.scrollLeft());
}
}
} else {
if($bar.data("status") == "on") {
$bar.hide().data("status", "off");
}
}
});
}, 50);
});
$(window).trigger("scroll.fixedbar");
});
Usage: Add the class fixed-scrollbar-container to your horizontally overflowed element, then include this code. If the container is updated or changes in size, run $(window).trigger("resize.fixedbar"); to update the bar.
Demo: http://jsfiddle.net/8zoks7wz/1/
#Mahn - I made a small update to the following function:
$('.fixed-scrollbar-container').each(function() {
var container = jQuery(this);
if (container[0].offsetWidth < container[0].scrollWidth) {
var bar = jQuery(fixedBarTemplate).appendTo(container).css(fixedBarCSS);
bar.scroll(function() {
container.scrollLeft(bar.scrollLeft());
});
bar.data("status", "off");
}
});
The if statement looks if the container offsetWidth is smaller than the scrollWidth. Else you will also get a fixed scrollbar if the content happens to be smaller than the container. I did not like having a disfunctional scrollbar, hence this edit.
How about restricting the height of the containing div so it stays within the body? You could then have the table scroll within that div.
Working jsfiddle here: http://jsfiddle.net/fybLK/
html, body {height: 100%; margin: 0; padding: 0;}
div {
width:500px;
max-height: 100%;
overflow:auto;
background: steelblue;}
table {
width: 1000px;
height: 1000px;
color: #fff;}
Here, I've set the html and body to 100% height so that the containing div can be sized.

Apply Twitter Bootstrap Validation Style and Message to ASP.NET MVC validation

How can I integrate ASP.NET MVC unobtrusive validation and Twitter Bootstrap? I want to have all those validation messages and styles appropriately.
A nice way of handling this if you're using Bootstrap 2 is...
Add this to your _Layout.cshtml:
<script type="text/javascript">
jQuery.validator.setDefaults({
highlight: function (element, errorClass, validClass) {
if (element.type === 'radio') {
this.findByName(element.name).addClass(errorClass).removeClass(validClass);
} else {
$(element).addClass(errorClass).removeClass(validClass);
$(element).closest('.control-group').removeClass('success').addClass('error');
}
},
unhighlight: function (element, errorClass, validClass) {
if (element.type === 'radio') {
this.findByName(element.name).removeClass(errorClass).addClass(validClass);
} else {
$(element).removeClass(errorClass).addClass(validClass);
$(element).closest('.control-group').removeClass('error').addClass('success');
}
}
});
$(function () {
$("span.field-validation-valid, span.field-validation-error").addClass('help-inline');
$("div.control-group").has("span.field-validation-error").addClass('error');
$("div.validation-summary-errors").has("li:visible").addClass("alert alert-block alert-error");
});
</script>
These are the posts where I found the code pieces above:
Integrating Bootstrap Error styling with MVC’s Unobtrusive Error Validation
Twitter Bootstrap validation styles with ASP.NET MVC
MVC Twitter Bootstrap unobtrusive error handling
UPDATE
Right now I needed to do the same when using Bootstrap 3. Here's the modifications necessary since the class names changed:
<script type="text/javascript">
jQuery.validator.setDefaults({
highlight: function (element, errorClass, validClass)
{
if (element.type === 'radio')
{
this.findByName(element.name).addClass(errorClass).removeClass(validClass);
} else
{
$(element).addClass(errorClass).removeClass(validClass);
$(element).closest('.form-group').removeClass('has-success').addClass('has-error');
}
},
unhighlight: function (element, errorClass, validClass)
{
if (element.type === 'radio')
{
this.findByName(element.name).removeClass(errorClass).addClass(validClass);
} else
{
$(element).removeClass(errorClass).addClass(validClass);
$(element).closest('.form-group').removeClass('has-error').addClass('has-success');
}
}
});
$(function () {
$("span.field-validation-valid, span.field-validation-error").addClass('help-block');
$("div.form-group").has("span.field-validation-error").addClass('has-error');
$("div.validation-summary-errors").has("li:visible").addClass("alert alert-block alert-danger");
});
</script>
Copy the css of the validators in your css file and change the color accordinlgly.
Something like this should do
.field-validation-error {
color: #b94a48;
display: inline-block;
*display: inline;
padding-left: 5px;
vertical-align: middle;
*zoom: 1;
}
.field-validation-valid {
display: none;
}
.input-validation-error {
/*
border: 1px solid #ff0000;
background-color: #ffeeee;
*/
color: #b94a48;
border-color: #b94a48;
}
.input-validation-error:focus {
border-color: #953b39;
-webkit-box-shadow: 0 0 6px #d59392;
-moz-box-shadow: 0 0 6px #d59392;
box-shadow: 0 0 6px #d59392;
}
.validation-summary-errors {
/*font-weight: bold;*/
color: #b94a48;
}
.validation-summary-valid {
display: none;
}
I suggest to include Bootstrapper in less format and do the same thing as Iridio suggested but in .less.
That way you could have something like:
.validation-summary-errors
{
.alert();
.alert-error();
}
.field-validation-error
{
.label();
.label-important();
}
so when bootstrapper will change you'll pick up the changes automatically.
Regular styles that handle visibility from MVC default Site.css will stay in place and handle visibility.
Why not just use css !important and call it a day:
/* Styles for validation helpers
-----------------------------------------------------------*/
.field-validation-error {
color: #f00 !important;
}
.field-validation-valid {
display: none;
}
.input-validation-error {
border: 1px solid #f00 !important;
background-color: #fee !important;
}
.validation-summary-errors {
font-weight: bold;
color: #f00;
}
.validation-summary-valid {
display: none;
}
On Bootstrap 3 you have to add:
.validation-summary-errors
{
.alert();
.alert-danger();
}
.field-validation-error
{
.label();
.label-danger();
}
you'll see something like that:
For the ValidationSummary, you can use the overload that allows you to specify htmlAttributes. This allows you to set it to use the Twitter Bootstrap alert css styles.
#Html.ValidationSummary(string.Empty, new { #class = "alert alert-danger" })
A similar overload exists for the ValidationMessage and ValidationMessageFor helper methods.
You can integrate MVC3 validation with Bootstrap framework by adding the following javascript to your page (View)
<script>
$(document).ready(function () {
/* Bootstrap Fix */
$.validator.setDefaults({
highlight: function (element) {
$(element).closest("div.control-group").addClass("error");
},
unhighlight: function (element) {
$(element).closest("div.control-group").removeClass("error");
}
});
var current_div;
$(".editor-label, .editor-field").each(function () {
var $this = $(this);
if ($this.hasClass("editor-label")) {
current_div = $('<div class="control-group"></div>').insertBefore(this);
}
current_div.append(this);
});
$(".editor-label").each(function () {
$(this).contents().unwrap();
});
$(".editor-field").each(function () {
$(this).addClass("controls");
$(this).removeClass("editor-field");
});
$("label").each(function () {
$(this).addClass("control-label");
});
$("span.field-validation-valid, span.field-validation-error").each(function () {
$(this).addClass("help-inline");
});
$("form").each(function () {
$(this).addClass("form-horizontal");
$(this).find("div.control-group").each(function () {
if ($(this).find("span.field-validation-error").length > 0) {
$(this).addClass("error");
}
});
});
});
</script>
Besides, on the Views (for example "Create.cshtml") make sure that the fields in the form are formatted as the following...
<div class="editor-label">
#Html.LabelFor(Function(model) model.Name)
</div>
<div class="editor-field">
#Html.EditorFor(Function(model) model.Name)
#Html.ValidationMessageFor(Function(model) model.Name)
</div>
For those using Bootstrap 3, the css classes have changed and the solutions above need modifications to work with Bootstrap 3. I have used the following with success with MVC 4 and Bootstrap 3. See this SO thread for more:
$(function () {
// any validation summary items should be encapsulated by a class alert and alert-danger
$('.validation-summary-errors').each(function () {
$(this).addClass('alert');
$(this).addClass('alert-danger');
});
// update validation fields on submission of form
$('form').submit(function () {
if ($(this).valid()) {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length == 0) {
$(this).removeClass('has-error');
$(this).addClass('has-success');
}
});
}
else {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).removeClass('has-success');
$(this).addClass('has-error');
}
});
$('.validation-summary-errors').each(function () {
if ($(this).hasClass('alert-danger') == false) {
$(this).addClass('alert');
$(this).addClass('alert-danger');
}
});
}
});
// check each form-group for errors on ready
$('form').each(function () {
$(this).find('div.form-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).addClass('has-error');
}
});
});
});
var page = function () {
//Update the validator
$.validator.setDefaults({
highlight: function (element) {
$(element).closest(".form-group").addClass("has-error");
$(element).closest(".form-group").removeClass("has-success");
},
unhighlight: function (element) {
$(element).closest(".form-group").removeClass("has-error");
$(element).closest(".form-group").addClass("has-success");
}
});
}();
You can add a few classes to your Site.css file:
/* styles for validation helpers */
.field-validation-error {
color: #b94a48;
}
.field-validation-valid {
display: none;
}
input.input-validation-error {
border: 1px solid #b94a48;
}
select.input-validation-error {
border: 1px solid #b94a48;
}
input[type="checkbox"].input-validation-error {
border: 0 none;
}
.validation-summary-errors {
color: #b94a48;
}
.validation-summary-valid {
display: none;
}
FYI: http://weblogs.asp.net/jdanforth/form-validation-formatting-in-asp-net-mvc-5-and-bootstrap-3
This will convert ValidationSummary() to a boostrap alert. You can include a little script to remove unnecessary classes and give a highlight to fields with problems.
#if (ViewData.ModelState.Any(x => x.Value.Errors.Any())) {
<div class="alert alert-danger">
×
<h4>Validation Errors</h4>
#Html.ValidationSummary()
</div>
}
<script>
$(".validation-summary-errors").removeClass("validation-summary-errors");
$(".input-validation-error").removeClass("input-validation-error").parent().addClass("has-error");
</script>
See more information at http://chadkuehn.com/convert-razor-validation-summary-into-bootstrap-alert/
This is a neat solution that gives you more control over how the ValidationSummary renders errors to the view. The Unordered List it produced did not look right inside the alert. Therefore, I simply looped through the errors and rendered them how I wanted - using paragraphs in this case. For example:
#if (ViewData.ModelState.Any(x => x.Value.Errors.Any()))
{
<div class="alert alert-danger" role="alert">
<a class="close" data-dismiss="alert">×</a>
#foreach (var modelError in Html.ViewData.ModelState.SelectMany(keyValuePair => keyValuePair.Value.Errors))
{
<p>#modelError.ErrorMessage</p>
}
</div>
}
Which results in a neat Validation Summary Alert:
The following worked for me:
$(function () {
// any validation summary items should be encapsulated by a class alert and alert-danger
$('.validation-summary-errors').each(function () {
$(this).addClass('alert');
$(this).addClass('alert-danger');
});
// update validation fields on submission of form
$('form').submit(function () {
if ($(this).valid()) {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length == 0) {
$(this).removeClass('has-error');
$(this).addClass('has-success');
}
});
}
else {
$(this).find('div.control-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).removeClass('has-success');
$(this).addClass('has-error');
}
});
$('.validation-summary-errors').each(function () {
if ($(this).hasClass('alert-danger') == false) {
$(this).addClass('alert');
$(this).addClass('alert-danger');
}
});
}
});
// check each form-group for errors on ready
$('form').each(function () {
$(this).find('div.form-group').each(function () {
if ($(this).find('span.field-validation-error').length > 0) {
$(this).addClass('has-error');
}
});
});
});
var page = function () {
//Update the validator
$.validator.setDefaults({
highlight: function (element) {
$(element).closest(".form-group").addClass("has-error");
$(element).closest(".form-group").removeClass("has-success");
},
unhighlight: function (element) {
$(element).closest(".form-group").removeClass("has-error");
$(element).closest(".form-group").addClass("has-success");
}
});
}();
