We will explain the code introduced in the HivePress code recipe.

Hide the budget field from the request form

<?php
add_filter(
	'hivepress/v1/models/request/attributes',
	function( $attributes ) {
		if ( isset( $attributes['budget'] ) ) {
			$attributes['budget']['editable'] = false;
			$attributes['budget']['filterable'] = false;
			$attributes['budget']['edit_field']['required'] = false;
		}
 
		return $attributes;
	},
	1000
);

Add to function.php

The code is added to function.php.

• Create a child theme and add it to function.php
• Added using the code snippets plugin

Please edit function.php in one of two ways.

Finally, go to Settings > Permalinks and click the [Update] button to reload the permalinks.
