Undefined $static_sections_string when saving using the advanced panel

[jools-r]

Warning on saving bulk settings from the advanced panel.

"Undefined variable $static_sections_string" in /bot_write_tab_customize/bot_write_tab_customize.php at line 815

= L815

The details appear to be saved correctly all the same.

Suggested fix: check for missing string first

if ($static_sections_string) {
    safe_update('txp_prefs', 'val= "'.doslash($static_sections_string).'", html="text_input" ', 'name = "bot_wtc_static_sections"');
}

Note to self:

• first check the state of sections to be hidden from the dropdown (stored in txp_prefs : bot_wtc_static_sections. These appear to be lost in the process.
• does this even need saving when processing the advanced settings panel?
