I have custom fields in my category. I'm using this tutorial to add custom fields to my categories.

I'm trying to output one of the custom fields on my category.php template but I'm unable to do so. The code I added to my template is:

<?php 
$term_slug = get_query_var( 'term' );
$taxonomyName = get_query_var( 'taxonomy' );
$current_term = get_term_by( 'slug', $term_slug, $taxonomyName );
$term_id = $current_term->term_id;
$saved_data = get_tax_meta($term_id,'text_field_id');
echo $saved_data;
?>

I have turned on debugging on and it shows error:

Notice: Trying to get property of non-object in /var/www/animedownloads.nu/public_html/wp-content/themes/twentytwelve/category.php on line 26

Here's the template code:

<?php

• categories
• custom-field
• taxonomy

Most probably the term was not found and $current_term returned as false:

$current_term = get_term_by( 'slug', $term_slug, $taxonomyName );
$term_id = false === $current_term->term_id ? null : $current_term->term_id;

According to the docs, get_term_by() return values are

Term Row (object or array) from database. Will return false if $taxonomy does not exist or $term was not found. Othewise returns object (by default) or array of fields depending on $output parameter.

Output the $current_term value and see if it is false:

$current_term = get_term_by( 'slug', $term_slug, $taxonomyName );
var_dump( $current_term );
$term_id = $current_term->term_id;
