ph_webclearblob PowerHome formula function

Description

Clears blob data in a PSP blob output page.

Syntax

ph_webclearblob ( )

Return value

Integer. Returns 0 if successful, 1 if an error ocurrs.

Usage

This function is only useful from within PSP pages. Every PSP page contains a blob output page. In a normal PSP page, output blob page is empty and the file is searched for formulas enclosed within PSP tags that are evaluated and then replaced with the results. The resulting file is then returned from the webserver. If data is added to the blob output page using the ph_webaddblob function, then the blob output page is instead returned from the webserver instead of the evaluated PSP. Use this function to clear data contained in the blob output page so that the evaluated PSP page will be returned.
