  • Manually verifying created users when using Laravel Email Verification

    Laravel 5.7 ships with bundled Email Verification. This is great if you want to make sure a user’s email address is valid (or at least that the user can access it) before allowing them access.

    Problem:
    What if you want to manually verify a user without sending them an email address? For example you might want to add or import a load of existing ‘known-good’ users to a migrated app. Or you might be creating Admin or System users that don’t really have accessible email addresses. There could be many reasons.

    At present as soon you register a user, the sendEmailVerificationNotification method is called. There’s a good breakdown of how this works in this Stack Overflow answer. If a user is manually created, then when they try to log in they’ll still see the “Verify your email address” message:

    Laravel's email verification message

    Solutions:
    Whether a user has verified their email address or not is indicated by a timestamp in the email_verified_at column of the User table¹. If this column is set to a valid timestamp upon user creation, the user will be ‘validated’ and no email will be sent. So… how can we set that timestamp?  (more…)

  • Fixing “[vue-loader] vue-template-compiler must be installed as a peer dependency”

    Problem:
    Whilst attempting to upgrade an old Laravel project, I hit the following error.

    Module build failed (from ./node_modules/vue-loader/lib/index.js):
Error: [vue-loader] vue-template-compiler must be installed as a peer dependency, or a compatible compiler implementation must be passed via options.

    Solution:
    After some searching of GitHub and stackoverflow, it turns out that The vue and vue-template-compiler module version must be the same. Here was my existing package.json:

  • Stop WordPress installing new bundled themes and plugins when the core is upgraded.

    Problem: Every time WordPress updates to a newer major version it tries to install the newest default Theme too, i.e. WP5.0 arrived with the theme Twenty Nineteen.

    In many – maybe MOST cases – we aren’t going to want this to happen on an existing WordPress installation, especially if you are already using a custom theme.

    Solution: Thankfully there’s a config value to stop this happening. The value is:

    define('CORE_UPGRADE_SKIP_NEW_BUNDLED', true);

    …and if you add this line to your `wp-config.php` file (usually found in the root of your site) it will skip new bundles items when the core is upgraded, as the name suggests.

  • Flush the DNS Cache on Mac OS El Capitan (using a nice quick alias)

    Updated June 2016: For OS X / 10.11 / El Capitan

    Problem: I’ve updated some Name Server records on a domain and I want to check they’ve propagated using Dig. When I dig mydomain.com ns I keep getting the old results.

    Solution: The local DNS cache on the machine needs to be cleared. As far as the OS is concerned, it’s already looked up that domain name and doesn’t need to do a fresh lookup until the domain record’s TTL (time to live) has expired.

    On OS X 10.11 El Capitan there are two things needed. Firstly clearing the Directory Service cache and secondly forcing mDNSResponder to restart. This can be done using two commands in Terminal¹:

    $ dscacheutil -flushcache
$ sudo killall -HUP mDNSResponder

  • Get terminal / bash prompt to show useful info

    Problem: Well it’s more of an irritation. My new hosting provider does allow SSH access, but when logged in the bash prompt looks like this, regardless of which account  I’m logged-in as, or where I am:

    -bash-4.2$

    What I want is for it to show something like:

    username@server:/current/path$

    Solution: The bash prompt can be customised via a profile script, ideally anything that loads when you log in like ‘.bash_profile’, ‘.bashrc’ or ‘.profile’. If one of these files doesn’t already exist in your home directory (check with ls -la ~ to list the contents) then create one. Here is an example of creating, editing and loading a login script to show a better prompt.

  • Updated for 1.2 & 1.3: Adding category depth tag to Shopp

    Problem: I needed to display sub categories of a category in category.php but only one level deep. Using:

    <?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')): ?>
    //display stuff
  <?php endwhile; ?>
<?php endif; ?>

    …displays all subcast AND their subcats. (more…)

  • Flush the DNS Cache on Yosemite (using a nice quick alias)

    Problem: I’ve updated some Name Server records on a domain and I want to check they’ve propagated using Dig. When I dig mydomain.com ns I keep getting the old results.

    Solution: The local DNS cache on the machine needs to be cleared. As far as the OS is concerned, it’s already looked up that domain name and doesn’t need to do a fresh lookup until the domain record’s TTL (time to live) has expired.

    On OS X Yosemite there are two name resolution caches that need emptying, Multicast DNS and Unicast DNS. They can be cleared / emptied / flushed using two commands in Terminal:

    sudo discoveryutil mdnsflushcache
sudo discoveryutil udnsflushcaches

  • Remove ‘ul’ and ‘li’ tags from WordPress menus while retaining all the classes

    Problem:
    I need to output a WordPress nav menu as a series of anchors surrounded by spans, within one nav element. Manipulating the args passed to wp_nav_menu() function will allow the <ul> element to be removed, and passing the output through ‘striptags’ can remove the <li> elements, but I end up losing all the link ancestry classes.

    Solution:
    If a ‘Walker’ class is used, the output from wp_nav_menu() can be controlled totally. Here’s an example that removes the list elements, adds a span around each item link, and adds the possibility of a separator string between each menu item.

    Add to your theme / header / etc: (more…)

  • Custom Ordering Shopp (wordpress plugin) products in just one category

    Problem: I’ve developed a site using the Shopp ecommerce WordPress Plugin and product ordering is set to ‘Price – Low to High’ at the Client’s request. Splendid. But now – for one category only – he want’s the Products to be give a custom order. In the Shopp presentation settings, ‘Product Order’ is set site-wide.

    Solution: I created a custom template for the category in question, then in that template loaded the specific category with the ‘order’ option set to ‘custom’. Here are some steps.

    1) Create the category specific template in the ‘Shopp’ theme templates directory in your WordPress theme. In my case the file was called category-truss.php as ‘truss’ is the slug of the category, and it’s a copy of my main category.php template file.

    2) At the top of category-truss.php add the API function shopp(‘storefront.category’) like so:

    <?php shopp('storefront','category','slug=truss&load=true&order=custom'); ?>
// load=true is needed to stop the functioning spitting out the category directly.
// slug is whatever your category's slug is. See the docs for more 'order' options.

    3) In the Shopp Admin area, edit the category you want to custom order, then use the ‘Arrange Products’ button/link. Then drag the products into the order you want and test.

    It might be that there’s an easier or better way to do this, if so please let me know in the comments!

  • Exclude a WordPress Post Category across the whole site… but not custom queries.

    Problem: On my latest project there’s a WordPress post category that only ever displays in a sidebar. I never want it to display in a ‘main’ loop posts on an archive page (whether it be the blog home, date archives, author archive etc etc. Until now I’ve been using ‘query_posts()’ and doing something like this in the main templates like home.php and index.php:

    <?php $catObj = get_category_by_slug('my-cat-slug');
query_posts( 'cat=-'.$catObj->term_id );
if ( have_posts() ) :
	while ( have_posts() ) : the_post(); ?>
		<!-- Show stuff init! -->
	<?php endwhile;
endif;?>

    This works… but I have to do it everywhere the loop is used, and when you dig into WordPress Templates that’s a lot of places.

    Solution: There’s always a way to do something globaly in WordPress using Filters, Actions, or Classes in your theme’s functions.php file (or a plugin even). In this case we can use the ‘pre_get_posts’ action in functions.php to exclude the category for all main queries: (more…)
