The posturl statement loads a resource from the internet, with form data.

---

Parameters

This statement has four parameters:

variable – is the name of the variable into which you wish to place the downloaded resource (usually text).

url – is the address of the resource to be loaded, for example "http://www.apple.com".

item – is the name of a form item expected by the server. Each name parameter must be paired with a value parameter (see below), you can have as many item/value pairs as the server calls for.

value – is the value of a form item.

Description

This statement loads a resource from the internet, with form data. In this example, two values are posted, Name and Email.

local webPage
posturl webPage,"http://www.somesite.com/register",
    "Name","John Smith",
    "Email","jsmith@xyzmail.com"
displaydata webPage

This function returns whatever data the server responds with, usually HTML text.

Note: If you need more control over loading the resource, use the url( function instead.

Note: The posturl statement is synchronous. This means that Panorama stops in its tracks until the communication is complete, so you should avoid this function if possible and use urltask( instead.
