1 install.core.inc | install_display_output($output, $install_state) |
Displays themed installer output and ends the page request.
Installation tasks should use backdrop_set_title() to set the desired page title, but otherwise this function takes care of generating the page output during every step of the installation.
Parameters
$output: The content to display on the main part of the page.
array $install_state: An array of information about the current installation state.
File
- core/
includes/ install.core.inc, line 752 - API functions for installing Backdrop.

// robots.txt rules are not read if the site is within domain.com/subfolder
// resulting in /subfolder/install.php being found through search engines.
// When settings.php is writeable this can be used via an external database
// leading a malicious user to gain php access to the server.
