    Fast Paginate for Laravel

    Fast Paginate for Laravel

    A fast implementation of offset/limit pagination for Laravel.

    This is a fast limit/offset pagination macro for Laravel. It can be used in place of the standard paginate methods. This package uses a SQL method similar to a "deferred join" to achieve this speedup. A deferred join is a technique that defers access to requested columns until after the offset and limit have been applied. In our case we don't actually do a join, but rather a where in with a subquery. Using this technique we create a subquery that can be optimized with specific indexes for...

    Laravel Honeypot

    Laravel Honeypot

    Preventing spam submitted through forms

    When adding a form to a public site, there's a risk that spam bots will try to submit it with fake values. Luckily, the majority of these bots are pretty dumb. You can thwart most of them by adding an invisible field to your form that should never contain a value when submitted. Such a field is called a honeypot. These spam bots will just fill all fields, including the honeypot. When a submission comes in with a filled honeypot field, this package will discard that request. On top of that...

    The Laravel magic you know, now applied to joins.

    The Laravel magic you know, now applied to joins. Joins are very useful in a lot of ways. If you are here, you most likely know about and use them.

    Laravel Localization

    Laravel Localization

    Easy localization for Laravel

    Easy i18n localization for Laravel, a useful tool to combine with Laravel localization classes. As you can modify the supportedLocales even by renaming their keys, it is possible to use the string uk instead of en-GB to provide custom lang url segments. Of course, you need to prevent any collisions with already existing keys and should stick to the convention as long as possible. But if you are using such a custom key, you have to store your mapping to the localesMapping array. This...
