# Link Data Field

The Link Data Field is a field which generates a button that links to another bloc. It also passes data to this other bloc through the url. This is a useful way of loading blocs straight from the data results and passing in data to the bloc you are about to load.

{% hint style="success" %}
This might be used in a situation where you want to load information about a certain company. By passing in the company name, and setting the [Filtered Field parameter](/blocworx-documentation/bloc-editor/managing-a-field/field-parameters/main-field-parameters.md#data-filtering-field), the data in the destination bloc will load just that companies data.
{% endhint %}

The button can appear either in the form, or in the results. The resulting url may look like the following: <https://example.blocworx.com/module/odm-app/bloc/1234?urlFieldSlugData={"company_name":"Blocworx"}> (note that this may appear as the following in the url bar: <https://example.blocworx.com/module/odm-app/bloc/1234?urlFieldSlugData=%7B%22company_name%22%3A%22Blocworx%22%7D> but is still correct)

In the above example the value of a field called Company Name is being passed into the url.

The resulting url may also be a custom url with normal parameters being added, e.g.\
<https://www.example.com?company_name=Blocworx>

Again in that example the field calledd Company Name is being passed in.
