Originated in

Troi URL Plug-in 3.0

Compatibility

FileMaker Pro 16 to 19

Considerations

Not every web server supports the DELETE method.
Secure connections (HTTPS) using SSL are also supported.
If you don’t specify a timeout, a default timeout of 15 seconds is used.

The length of the URL is limited, by both the plug-in and receiving web servers. A lot of web servers don’t support URLs longer than 2048 characters. Note that the plug-in has higher limits of 32867 characters for the URL.

Note that starting with v6.0 the plug-in no longer shows a progress dialog on nacOS.

Example

TURL_Delete ( "-Unused" ; "http://www.example.com/data/user123/mydata.txt" )

This will send the request to the web server to delete the file at the location /data/user123/mydata.txt.

Example 2

We assume that in your FileMaker file the following field is defined:

 ImageName         		Text

The field ImageName should contain the name of the image, for example “img123.jpg”.

In a script add the following script steps:

Set Variable [ $thebaseURL ; "http://www.photos.com/images/" ]
Set Field[ resultText ; TURL_Delete ( "-noDialog" ; $thebaseURL & ImageName ) ]

This will ask the web server to delete the image at the specified location on the web server: “http://www.photos.com/images/img123.jpg”. Note that web servers might not support the DELETE method or refuse this DELETE request.
