Meta Box

Hi,

I think there's a misunderstanding here. The extension provides UI for users to enter the config or specify the path to the config file (as instructed here). It doesn't work if you specify the path to the config file in your code.

Hi, currently, the plugin doesn't support showing the inputs in the frontend yet.

I have a solution for that, but it requires both the core plugin and the extension to update. I'm thinking about backward compatibility.

Ah, sorry, for image fields, the returned value is always an array. You need to change the code to:

$object_imgs = isset( $sector['rw_sector-object-image'] ) ? $sector['rw_sector-object-image'] : array();
if ( ! empty( $object_imgs ) ) {
    foreach ( $object_imgs as $object_img ) {
        echo '<div class="sector-object-img">
            <div class="slider slider-for">
            <img src="' . wp_get_attachment_image_url( $object_img, 'type=image_advanced&size=full&multiple=true' ) . '">
        </div>
        </div>';
    }
}

Just tried your code and 48 shows up as default value for me. Please note that it works only for the posts where the meta box hasn't been saved. You can check it with new posts.

This is resolved on Github: https://github.com/rilwis/meta-box/issues/1001.

No problem, here you are:

<?php
$prefix = '';
$sectors = rwmb_meta( "{$prefix}sector" );
if ( ! empty( $sectors ) ) {
	foreach ( $sectors as $sector ) {
		$sector_heading = isset( $sector["{$prefix}sector-heading"] ) ? $sector["{$prefix}sector-heading"] : '';
		echo $sector_heading;

		$sector_title = isset( $sector["{$prefix}sector-title"] ) ? $sector["{$prefix}sector-title"] : '';
		echo $sector_title;

		$objects = isset( $sector["{$prefix}sector-object"] ) ? $sector["{$prefix}sector-object"] : array();
		foreach ( $objects as $object ) {
			$object_img = isset( $object["{$prefix}sector-object-img"] ) ? $object["{$prefix}sector-object-img"] : '';
			if ( $object_img ) {
				echo '<img src="' . wp_get_attachment_image_url( $object_img, 'size' ) . '">';
			}
			$object_desc = isset( $object["{$prefix}sector-object-description"] ) ? $object["{$prefix}sector-object-description"] : '';
			echo $object_desc;
		}
	}
}

That also works :). Remember to strip_tags on the frontend when you retrieve the meta value 🙂
