Laravel with SSL through Cloudflare on Heroku.

 

I deployed a Laravel app on Heroku, using Cloudflare for SSL. As a quick note, here’s how I did it.

  1. Deploy the app on Heroku and make sure everything works fine using the heroku app url.
  2. Add the domain names to your app in Heroku (in the settings tab for the app). Make sure you add both the root domain and www if you’re using it (example.com, www.example.com). Don’t activate SSL in Heroku.
  3. Add the site to your Cloudflare account (choose the free plan, when asked).
  4. Point your domain to Cloudflare by changing the name servers  (at the registrars control panel) to the ones Cloudflare gives you when adding the site.
  5. Wait for the name server changes to go through. It will be notified under the Overview tab on Cloudflare. When this is done you will administer the domain records on Cloudflare instead of your domain regristrar.
  6. Remove all the DNS records you don’t need, under the DNS tab in Cloudflare.  For the next step to work you need to remove the A records for the root domain – since you won’t point it to an IP address, but a domain on Heroku.
  7. Point Cloudflare to your Heroku app by adding cname records pointing to the Heroku app url.
    Like this.

    Type: CNAME
    Name: jymden.com
    Domain name: myapp.herokuapp.com

    Type: CNAME
    Name: www
    Domain name: myapp.herokuapp.com

  8. In Cloudflare, go to the Crypto tab. Set SSL to Full:
  9. Make sure your Universal SSL certificate is activated. This will happen automatically a little while after adding the site to Cloudflare (up to 24 hours, but usually faster).  When it’s activated you’ll see it a bit down in the Crypto tab, like this:
  10. Prepare your Laravel app to use https by adding this to the boot function AppServiceProvider.php (App/Providers):
    public function boot(UrlGenerator $url)
    {
        if (env('APP_ENV') !== 'local') {
            $url->forceSchema('https');
        }
    }
    

    NOTE: if you’re using Laravel 5.4 or higher it’s forceScheme instead of forceSchema

    Also, you need to set your Laravel environment variable APP_ENV to production (or at least something else than local). Do this in the Heroku app settings tab.

  11. Now try to enter your site with https. It might take a while for it to kick in.
  12. When you see that https is working correctly, go in to the Page Rules tab in Cloudflare. Click Create Page Rule and add the rule to always use https for the domain. Use wildcards to cover all urls. Like this:
  13. Drink coffee.

(PHP) Sort array of objects by property value

usort($myArray, function($a, $b)
{
    return strcmp($a->myPropery, $b->myPropery);
});

Sort by predefined order:

$predefinedOrder = array(1,5,2,6);

usort($arrayOfObjects, function ($a, $b) use ($predefinedOrder ) {

    $flipped = array_flip($predefinedOrder);
    $left = $flipped[$a->myPropery)];
    $right = $flipped[$b->myPropery)];
    return $left >= $right;
});

(PHP) Make Laravel migration to change table

Create migration in console:

php artisan make:migration add_mycolumn_to_mytable

Use Schema::table() to access existing table (instead of Schema::create() for creating new tables)

public function up()
{
    Schema::table('mytable', function($table) {
        $table->text('mycolumn');
    });
}

public function down()
{
    Schema::table('mytable', function($table) {
        $table->text('mycolumn');
    });
}

Then run migrations:

php artisan migrate

(WordPress) Generate post title from custom field

I had a custom post type that only used custom fields, so I needed to generate a post title from there.
Here’s one way. You can if course chain as many if else as you want to check other types.

functions.php

function custom_post_type_title($post_id)
{
    global $wpdb;
    if (get_post_type($post_id) == 'staff') {
        $name = get_post_custom_values('name');
        $title = $name[0];
        $where = array('ID' => $post_id);
        $wpdb->update($wpdb->posts, array('post_title' => $title), $where);
    } 
}

add_action('save_post', 'custom_post_type_title');

(Javascript) Newline to br

Replaces newline characters with <br> tags in the same style as the php nl2br function

// lewline to br - php style 
function nl2br (str, is_xhtml) {
        var breakTag = (is_xhtml || typeof is_xhtml === 'undefined') ? '<br />' : '<br>';
        return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1'+ breakTag +'$2');
    }
