Download the PHP package hashemi/queryfilter without Composer

Laravel QueryFilter

A simple & dynamic package for your eloquent query in laravel. It will help you to write query logic individual for each parameter.

Installation

You can start it from composer. Go to your terminal and run this command from your project root directory.

• If you're using Laravel, then Laravel will automatically discover the package. In case it doesn't discover the package then add the following provider in your config/app.php's providers array.

• If you're using Lumen, then you'll have to add the following snippet in your bootstrap/app.php file.

Usage

Suppose you want use query-filters on User model for query. Laravel QueryFilter provide Filterable trait . You need to use it on your model. It will add a scope filter on your model. Like,

Now, you need to create your query filter file where you will write sql logic to generate sql by passing parameter. You can create your filter file by using command,

This command will create Filters directory on your app/ directory. So, you can find the file on app/Filters/UserFilter.php. Every method of filter class, represent your passing parameter key. You need to pass your parameter snake case and your method name will be like apply<ParamterName>Property format. Property name must be write in Pascal case.

After create that file, when you use your model on you controller to query something, you need to use your scope and pass UserFilter class as a parameter. You controller will be look like,

If you want to pass your custom queries on filter, you can also do that in your filter,

And on your app\Filters\UserFilter.php file, you can do something like it,

That's it.

Convention

• Your *Filter class should have methods in apply*Property format. Where the * will be replaced by the StudlyCase Property names. So, if your field name is first_name, then the method name should be applyFirstNameProperty().
• If you're passing an extra data to the Model's filter scope like Model::filter($filter, ['id' => 4]), then the provided array will take precedence over the request's data.

Caveat

If your request & provided array to the filter scope cannot find any suitable method, then it'll return the whole table data as select * from your_table. Be aware of this issue.
