Actions, Filters & Overrides

PHP4 Min.Updated: October 31, 2026

Where settings aren’t enough, you step in through a template copy in your theme and through WordPress filters – update-safe and without changing the plugin itself.

Replacing the exhibitor page in the theme

For an exhibitor’s single page the plugin first looks in the active theme (or child theme) for event-exhibitor-manager/single-event-exhibitor.php and only then uses its own template. The subfolder is named like the plugin folder; the plugin ignores a file of the same name directly in the theme folder.

Template in the plugin	Copy in the theme
`event-exhibitor-manager/templates/single-exhibitor.php`	`your-theme/event-exhibitor-manager/single-event-exhibitor.php`

Copies go stale

A template copy no longer receives plugin updates. Compare it with the original after updates – or, where possible, change things with CSS only. The pop-up is built with JavaScript and isn’t affected by the copy.

Filters

Filter	Default	Purpose
`eem_tools_capability`	`edit_others_posts`	Who may use dashboard, Mass Editor and Import / Export. `manage_options` restores the old behavior (administrators only).
`eem_settings_capability`	`manage_options`	Who sees and saves the writing settings tabs (design, functions, labels, security, API).
`eem_settings_page_capability`	`edit_posts`	Who may open the settings page at all (generator, about).
`eem_allow_contributor_uploads`	`true`	Whether contributors may upload logos and gallery images in the back end. `false` restores the WordPress default.
`eem_country_list`	250 countries	Country names and ISO codes for selection and import.
`eem_settings_backup_excluded_keys`	delete option	Options that should not go into the settings backup.

Examples for functions.php

Tools for administrators only

add_filter( 'eem_tools_capability', function () {
    return 'manage_options';
} );

Contributors without media upload

add_filter( 'eem_allow_contributor_uploads', '__return_false' );

Keep your own option out of the backup

add_filter( 'eem_settings_backup_excluded_keys', function ( $keys ) {
    $keys[] = 'eem_my_internal_value';
    return $keys;
} );

Reading data from outside

For apps and partner websites the public REST API is the right way – with a fixed data format. Styling without a template copy: CSS customizing.
