Constants

EXPERT_LOOKUP_THE_CONTENT

Settings container key to enable the `the_content` hook.

public array<string|int, mixed> EXPERT_LOOKUP_THE_CONTENT = array('key' => 'footnote_inputfield_expert_lookup_the_content', 'name' => '<code>the_content()</code>', 'description' => '<a href="https://developer.wordpress.org/reference/hooks/the_content/" target="_blank">https://developer.wordpress.org/reference/hooks/the_content/</a>', 'default_value' => true, 'type' => 'boolean', 'input_type' => 'checkbox')

Move from Settings to ReferenceContainerSettingsGroup. Convert from string to array. Convert setting data type from string to boolean.

EXPERT_LOOKUP_THE_CONTENT_PRIORITY_LEVEL

Settings container key for `the_content` hook priority level.

public array<string|int, mixed> EXPERT_LOOKUP_THE_CONTENT_PRIORITY_LEVEL = array('key' => 'footnote_inputfield_expert_lookup_the_content_priority_level', 'name' => '<code>the_content()</code> Priority Level', 'description' => 'The priority level determines whether Footnotes is executed timely before other plugins, and how the reference container is positioned relative to other features. 9223372036854775807 is lowest priority, 0 is highest. To set priority level to lowest, set it to -1, interpreted as 9223372036854775807, the constant <code>PHP_INT_MAX</code>. For <code>the_content</code>, this figure must be lower than 99 so that certain strings added by a plugin running at 99 may not be mistaken as a footnote. This makes also sure that the reference container displays above a feature inserted by a plugin running at 1200.', 'default_value' => 98, 'type' => 'number', 'input_type' => 'number', 'input_max' => PHP_INT_MAX, 'input_min' => -1)

Priority level of the_content and of widget_text as the only relevant hooks must be less than 99 because social buttons may yield scripts that contain the strings ‘((’ and ‘))’ (i.e., the default footnote start and end shortcodes), which causes issues with fake footnotes.

Setting the_content priority to 10 instead of PHP_INT_MAX makes the footnotes reference container display beneath the post and above other features added by other plugins, e.g. related post lists and social buttons.

For the YARPP plugin to display related posts below the Footnotes reference container, priority needs to be at least 1,200.

PHP_INT_MAX cannot be reset by leaving the number box empty, because WebKit browsers don't allow it, so we must resort to -1.

These are checkboxes; the keyword checked is converted to true, whilst an empty string (the default) is converted to false.

Hooks should all be enabled by default to prevent users from thinking at first that the feature is broken in post titles (see here for more information).

In titles, footnotes are still buggy, because WordPress uses the title string in menus and in the title element, but Footnotes doesn't delete footnotes in them.

EXPERT_LOOKUP_THE_TITLE_PRIORITY_LEVEL

Settings container key for `the_title` hook priority level.

public array<string|int, mixed> EXPERT_LOOKUP_THE_TITLE_PRIORITY_LEVEL = array('key' => 'footnote_inputfield_expert_lookup_the_title_priority_level', 'name' => '<code>the_title()</code> Priority Level', 'description' => 'The priority level determines whether Footnotes is executed timely before other plugins, and how the reference container is positioned relative to other features. 9223372036854775807 is lowest priority, 0 is highest.

public array<string|int, mixed> EXPERT_LOOKUP_WIDGET_TEXT = array('key' => 'footnote_inputfield_expert_lookup_widget_text', 'name' => '<code>widget_text()</code>', 'description' => '<a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/widget_text" target="_blank">https://codex.wordpress.org/Plugin_API/Filter_Reference/widget_text</a>.

If they should not, this hook must be disabled.', 'default_value' => false, 'type' => 'boolean', 'input_type' => 'checkbox')

The widget_text hook must be disabled by default, because it causes multiple reference containers to appear in Elementor accordions, but it must be enabled if multiple reference containers are desired, as in Elementor toggles.
