Hello Vlad,

Thank you for posting here. Please look at the following function you can use to save the xprofile field value.

Please check

Hi Vlad,
You will need to write a form handler. Something that will handle the submission of your form. in order to do that, you need to identify your form.

I had a look at your form code above and I am not sure what you want to achieve with it. Can you please help us understand what you are trying to achieve with it? Ravi or I will be able to assist you better then.

Hi Vlad,

The code to update will have 2 parts. A form and a handler. The form is placed somewhere in your group screen and the handler code should be in your theme’s functions.php.

Here is your form updated slightly.

    <form id="myform" method='post' action="">

        <select id="mylogins" name="mylogins" class='livesearch' required>

            <option value="">Please select login</option>

			<?php if ( bp_group_has_members( bp_ajax_querystring( 'group_members' ) ) ) : ?>
				<?php
				while ( bp_group_members() ) :
					bp_group_the_member();
					?>
                    <option value='<?php echo bp_get_member_user_id(); ?>'><?php bp_member_user_nicename(); ?><?php bp_group_member_name(); ?></option>
				<?php endwhile; ?>

			<?php endif; ?>
			<?php $group_id = bp_get_group_id( groups_get_current_group() ); ?>
        </select>
        <input type="hidden" name="group-meta-form-group-id" value="<?php echo esc_attr( $group_id ); ?>">
        <input type="text" placeholder="Enter value" name="my-field-name" required>

		<?php wp_nonce_field( '_group_meta_update_' . $group_id, '_group_meta_update_nonce' ); ?>
        <input type="submit" id="myform" value="Save">
    </form>

and here is the handler code

add_action( 'bp_actions', function () {
	// make sure it is our form submission.
	if ( ! isset( $_POST['group-meta-form-group-id'] ) ) {
		return;
	}

	$field = 'My Field Name'; // Please Update it with Your Xprofile field id or name.
	// Only logged users can access it.
	if ( ! is_user_logged_in() ) {
		return;
	}

	$grooup_id = absint( $_POST['group-meta-form-group-id'] );
	if ( ! $grooup_id || ! wp_verify_nonce( $_POST['_group_meta_update_nonce'], '_group_meta_update_' . $grooup_id ) ) {
		return;
	}

	$selected_user_id = isset( $_POST['mylogins'] ) ? absint( wp_unslash( $_POST['mylogins'] ) ) : 0;

	if ( ! $selected_user_id || ! get_user_by( 'id', $selected_user_id ) ) {
		return;
	}

	$logged_user_id = get_current_user_id();

	if ( is_super_admin( $logged_user_id ) || groups_is_user_admin( $logged_user_id, $grooup_id ) || groups_is_user_mod( $logged_user_id, $grooup_id ) ) {
		// update profile.

		$value = isset( $_POST['my-field-name'] ) ? sanitize_text_field( wp_unslash( $_POST['my-field-name'] ) ) : '';

		if ( empty( $value ) ) {
			xprofile_delete_field_data( $field, $selected_user_id );
		} else {
			xprofile_set_field_data( $field, $selected_user_id, $value );
		}
		bp_core_add_message( __( 'Updated successfully.', 'some -text-domain' ), 'success' );
	}
} );

I haven’t tested it but I hope they will work fine.

Please give it a try and adapt as you need it.

Hi Vlad,
Thank you for the kind words.

I am glad it worked 🙂

PS:- You are using the Group slug as Profile field name. I assume you have create an xprofile field for each of group.
