Question

Managing a variable number of parameters is now made possible with the new

In my code, I have a sentence that looks like this:

.state('category', {
    url: '/categories/:parameter',
    templateUrl: 'templates/common/categories.html',
    controller: 'categoriesCtrl',
    resolve : {
    categoryList: ['Products', function (Products) {
        return Products.listByCategories($stateParams.parameter);
    }]
    }
})

It's for a simple web shop where products are listed based on categories. The issue is that the number of categories needs to be dynamic. For example, I might request:

/categories/shoes
/categories/shoes/man/
/categories/shoes/man/running
/categories/shoes/man/running/nike

The parameter must adjust dynamically, but I'm not sure how to achieve this. Can someone provide some guidance? Thank you!

There are two options to consider:

Option 1 (not recommended but possible):

$stateProvider.state('category', {
    // You can modify all patterns, but ensure {0, x} allows for empty spaces between slashes.
    url: '/categories/{item:[a-z0-9\-]{0,8}}/{gender:[a-z]{0,6}}/{sport:[a-z]{0,12}}/{company:[a-z0-9]{0,8}}',
    controller: function($stateParams) {
        console.log($stateParams);
    }
});

You can use:

/categories/shoes///
/categories/shoes/man//
/categories/shoes/man/running/
```
/categories/shoes/man/running/nike
```

Option 2 (preferred):

$stateProvider.state('category', {
    // The pattern can be modified except for \/
    url: '/categories/{details:[a-z0-9\/\-]{0,20}}',
    controller: function($stateParams) {
        console.log($stateParams);
    }
});

Now you can use any combination starting with /categories/:

```
/categories/shoes/man/running/nike
```

Simply utilize the split() method and specify that:

Key 0 will contain items.
Key 1 will contain gender.

In cases where gender is input instead of item, compare key 0 to the

items whitelist(array with items)

. Enjoy!

In my experience, I have observed that categories are often separated by a '-' or a '+' instead of slashes. This method is preferred because slashes can cause issues with URL routers, especially in the case of Angular.

Alternatively, you could consider parsing the entire URL and handling the slashes manually. However, using a '-' or '+' allows you to parse the directory as a string and then split it based on the delimiter to generate a list of categories for searching purposes.
