There are instances where a person may want to redirect the user to checkout after adding items to cart ie. if they use Woocommerce booking appointment and can only book one time. The below code snippet allows for changing the behaviour of the Add to Cart button. Code add_filter( 'woocommerce_add_to_cart_redirect', 'themename_add_to_cart_redirect' ); function themename_add_to_cart_redirect( $url ) { return get_permalink( get_option( 'woocommerce_checkout_page_id' ) ); } Where to add this Code snippet? Usually, the code is added in functions.php of your child theme. As shown below: /path/to/wordpress/wp-content/themes/mytheme-child/functions.php I don't have access to this functions.php As an alternative, you can also install and use a plugin called Code Snippets  from the admin. Log into your WordPress admin Click Plugins Click Add New Search for Code Snippets Click Install Now under "Code Snippets" Activ...

Redirect to Another Page With Javascript // window.location window.location.replace('http://www.example.com') window.location.assign('http://www.example.com') window.location.href = 'http://www.example.com' document.location.href = '/path' // window.history window.history.back() window.history.go(-1) // window.navigate; ONLY for old versions of Internet Explorer window.navigate('top.jsp') Redirect to Another Page With JQuery $(location).attr('href','http://www.example.com') $(window).attr('location','http://www.example.com') $(location).prop('href', 'http://www.example.com')

For a single element, it is very easy to check if an element is hidden or visible: $(element).is(":visible"); $(element).is(":hidden"); To match all elements, use the ff: $('element:hidden'); $('element:visible') You can also check the CSS display property: if ( $(selector).css('display') == 'none' ) { // is hidden } else { // is visible }

This simple snippet shows how to open Bootstrap Modal on form submission using jQuery. Bootstrap has provided functions you can use to manually manipulate the modal. $('#myModal').modal('toggle'); $('#myModal').modal('show'); $('#myModal').modal('hide'); Here is an example form <form action="/process" onsubmit="openModal()" id="myForm"> Call the function manually function openModal(){ $('#myModal').modal('show'); return false; } Using the jQuery  Event Listener $('#myForm').on('submit', function(e){ $('#myModal').modal('show'); }); See Demo in CodePen See the Pen Bootstrap Modal on Form Submit by Hana Piers ( @hanapiers ) on CodePen .

Bootstrap's Modal default behavior is that it closes when you click outside the window. To disable it, Bootstrap, provided simple solution: With jQuery You can initialize the modal settings backdrop property to "static" $('#myModal').modal({ backdrop: 'static', keyboard: false }); You may noticed that we also set keyboard property to false. This is to disable the use of ESC button to close the modal. Though I would recommend this only as alternative. It is still preferred to use HTML and Bootstrap has just made it possible. Use backdrop data attribute According to Boostrap, if you set data-backdrop to "static", this will disable the modal from closing. <a data-controls-modal="#yourId" data-backdrop="static" data-keyboard="false" href="#">

In Javascript, you can make the first word uppercase by using the technique below. function capitalize(str) { return str.charAt(0).toUpperCase() + str.slice(1); } var str = "lorem ipsum dolor"; capitalize(str); // output: "Lorem ipsum dolor" To explain what's going on, the function takes the first letter of given string and convert it to uppercase then append to the rest of the given string. We can modify the String.prototype if you don't mind a little setback on the performance. String.prototype.capitalize = function() { return this.charAt(0).toUpperCase() + this.slice(1); } Now we can call the function in object oriented way: var str = "lorem ipsum dolor"; console.log(str.capitalize()); // output: "Lorem ipsum dolor"

This tutorial assumes that you already know what a query string is. If you are looking for a way to get the query string values and assign to a variable, then check the following block of codes. Do note that this is only pure Javascript. No need for plugins or libraries. var queryString = {}; var params = location.search.substr(1).split('&'); params.forEach(function( param ){     [name, value] = param.split('=');     queryString[name] = decodeURIComponent((value).replace(/\+/g, '%20')); }); // check the output console.log(queryString); In the above code, we use location.search which is the way to get the query string. The result of location.search . would be a string type like this: ?key1=value1&key2=value2 To get the desired result we want, we first remove the '?' mark with .substr(1) , then split the string with delimiter '&' The resulting array is then looped through using .forEach() . For each array item we then spli...

Although the title says jQuery  in it, I will also provide Javascript solution for this snippet. Live Demo at CodePen Suppose we have the following checkbox input: <input type="checkbox" name="colors" value="red" /> Red <input type="checkbox" name="colors" value="green" /> Green <input type="checkbox" name="colors" value="blue" /> Blue in jQuery: var colors = $('[name="colors"]'); // non-element specific var colors = $('input[name="colors"]'); // specific to "input" elements only in JavaScript: // returns array of elements with name="colors" var colors = document.getElementsByName('colors'); var colors = document.querySelectorAll('[name="colors"]'); // returns first element with name="colors" var colors = document.getElementsByName('colors')[0]; var colors = documen...

There are many ways to pass PHP variables to Javascript but I will only cover 3 most common: 1. Echo the data. 2. Use a hidden field or element. 3. Use a data attribute 1. Echo the data. The first one which is the simplest can be done as follows: var data = <?php echo $data;  ?>; But the above code can cause an issue depending on the data type and it's value, so we use json_encode to convert the data. In PHP: $name = "John O'Reily";     // a string with single quote $age = 14;                           // an integer number $address = array(                // an array     'street' => '123 Street',     'city' => 'XYZ City' ); In Javascript: var name = <?php echo json_encode($name);  ?>; var age = parseInt(<?php echo json_encode($age);  ?>); var address = <?php echo json_encode($address);  ?...

Updating your website's copyright year on annual basis can be annoying, to make your copyright year dynamically change, simply use the new Date.getFullYear(); code as shown in the example below. Live Demo  at CodePen the HTML: &copy; 1997 - <span id="currentYear"></span> // desired ouput: © 1997 - 2017 on pure Javascript: document.getElementById('currentYear').innerHTML = new Date().getFullYear(); or if you use jQuery [ CodePen demo ]: $('#currentYear').html(new Date().getFullYear());

Download VirtualBox and Vagrant Create a directory for your virtual environment mkdir vagrant_env1 cd vagrant_env1 Install your preferred box (Ubuntu 12.04 LTS 64-bit for this example): vagrant init hashicorp/precise64 or vagrant init vagrant box add hashicorp/precise64 You may check this HashiCorp's Atlas box catalog for more type of boxes. By the way, a "box" is a base image of an operating system. This enables you to quickly clone a virtual machine rather than starting from scratch, which would be a slow and tedious process. Installing may take some time, but after that, you can re-use this box when you want to create another virtual environment. Now run vagrant up: vagrant up To enter the virtual machine, simply SSH: vagrant ssh
