# Form input parameters

## Form input parameters <a href="#parametrywejscioweformularza-parametrywejscioweformularza" id="parametrywejscioweformularza-parametrywejscioweformularza"></a>

To pass parameters via the URL to the form, we need to define a variable or add the component to which we want to pass this parameter.

In the application edit view, in the left menu, select the option **Input parameters**, and then **Add input parameter**. As the value **Alias** we enter the alias name of the injected variable. **Alias** will be part of the URL address to the application page. As **Request component** we choose a field from the application or a session variable. We can also assign it a default value, which will be used if the parameter in the URL is not provided.

### **Ways to pass parameters**

1. Passing the parameter directly in the URL:\
   \
   <http://adres-do-platformy/?parametr=wartosc#/nazwa-wniosku>

{% hint style="danger" %}
**Passing the parameter**

You must pass the parameter correctly in the address. Correct example: <http://adres-do-platformy/?parametr=wartosc#/nazwa-wniosku>. The parameter must be before #.
{% endhint %}

2. Passing the parameter as a hidden input field:

```
<form action="#/application-name">
   <input class="redirect-button" type="submit" value="Go"/>
   <input type="hidden" id="parametr" name="parametr" value="wartosc"/>
</form>
```
