Shamim's Plugins

You can use hook ( action and filter ) to change any other function.

add following code in your theme’s (child theme’s if any) functions.php

add_action( 'fep_display_before_directory', function(){
	?><script type="text/javascript">
	jQuery(document).ready(function($){
		var delay = (function(){
		  var timer = 0;
		  return function(callback, ms){
		    clearTimeout (timer);
		    timer = setTimeout(callback, ms);
		  };
		})();

		$('.fep-directory-search-form-field').keyup(function() {
			delay(function(){
		      $('#fep-directory-search-form').submit();
		  }, 1000 );
		});
	});
	</script><?php
});

Please wait for next version. It will be added in plugin, so you do not need any custom code for this. Next version will be released next week.

Please add following code in your theme’s (child theme’s if any) functions.php

add_filter( 'fep_directory_output', function( $directory ){
	$checkbox = '<label><input type="checkbox" class="fep-cus-select-all" />'.__('Select all').'</label>';
	$checkbox .= '<script type="text/javascript"> jQuery(document).ready(function(){';
	$checkbox .= 'jQuery("#fep-table .fep-cus-select-all").change(function(){';
	$checkbox .= 'jQuery( \'#fep-table input[type="checkbox"]\' ).prop("checked", this.checked);';
	$checkbox .= '})}); </script>';
	
	return str_replace( '<div id="fep-table" class="fep-table fep-odd-even">', '<div id="fep-table" class="fep-table fep-odd-even">' . $checkbox, $directory);
});

It will show a checkbox in “Directory” to select all users from directory. Then from dropdown select “Send message”.

1. Plugin must be installed in plugin directory (normally /wp-content/plugins/)
2. wp-content/themes/spacious-child/front-end-pm/ can contain any files from front-end-pm-pro/templates directory

It should not delete any file.
I will try to investigate it more.
What is your language code?
did you put your language file in wp-content/languages/plugins folder?

Please follow step by step
1. Remove all changes you have made for this plugin.
2. Inside your child theme create a folder called “front-end-pm”. So full path will be /wp-test/wp-content/themes/spacious-child/front-end-pm/
3. in this folder copy “viewmessage.php” and change this file as you need ( do not change file name)

add following code in your theme’s ( child theme’s if any) functions.php

add_filter('fep_get_user_option', function( $value, $option, $default, $userid ){
    global $ultimatemember;
    if( ! $userid )
    $userid  = get_current_user_id();

    if( 'allow_ann' == $option && ! $ultimatemember->user->is_approved( $userid ) ){
        $value = 0;
    }
    return $value;
}, 10, 4);
