Laravel 8.78 Released


January 5th, 2022

Laravel 8.78 Released

The Laravel team released 8.78 with the ability to add custom rules to default password validation rules, a mergeIfMissing() request method, asserting batch counts in tests, and the latest changes in the v8.x branch.

Define Extra Default Password Validation Rules

Ash Allen contributed the ability to define custom validation rules that will run as part of default password rules using the rules() method:

Password::defaults(function () {
return Password::min(8)
->rules(new ZxcvbnRule());

The rules() method accepts a single rule, an array of rules, or a closure for a closure validation rule.

Merge Request Data if Missing

David Peach contributed a mergeIfMissing() HTTP request method that will merge new input into the request’s input if the key is missing from the request.

For example, if you uncheck a form checkbox input it is not sent to the server. You might have to write something like the following:

if ($request->missing('boolean_setting')) {
$request->merge(['boolean_setting' => 0]);

Now you can define values that are merged with the request if missing:

$request->mergeIfMissing(['boolean_setting' => 0])

Assert Batch Count

@Chrysanthos contributed an assertBatchCount() method to the Bus facade, which asserts how many batches have been dispatched:


HTML String Method

Lars Klopstra contributed a toHtmlString() method to Str and Stringable:

// Before
new HtmlString(Str::of($content)->markdown());
// After
