Vendor maximum price

OK, what type of products you are allowing to create by vendors?

HI,

Please use this code to your site –

add_filter( 'wcfm_form_custom_validation', function( $wcfm_products_manage_form_data, $form_manager ) {
  if( $form_manager == 'product_manage' ) {
  	if( $wcfm_products_manage_form_data['product_type'] == 'simple' ) {
			$regular_price = isset( $wcfm_products_manage_form_data['regular_price'] ) ? wc_clean( $wcfm_products_manage_form_data['regular_price'] ) : '';
			
			if( $regular_price && ( $regular_price > 30 ) ) {
				$custom_validation_results['has_error'] = true;
				$custom_validation_results['message'] = 'Product maximum price should not be more than 30';
				return $custom_validation_results;
			}
		} elseif( $wcfm_products_manage_form_data['product_type'] == 'variable' ) {
			if(isset($wcfm_products_manage_form_data['variations']) && !empty($wcfm_products_manage_form_data['variations'])) {
			  foreach($wcfm_products_manage_form_data['variations'] as $variations) {
			  	$regular_price = isset( $variations['regular_price'] ) ? wc_clean( $variations['regular_price'] ) : '';
					
					if( $regular_price && ( $regular_price > 30 ) ) {
						$custom_validation_results['has_error'] = true;
						$custom_validation_results['message'] = 'Product maximum price should not be more than 30';
						return $custom_validation_results;
					}
			  }
			}
		}
  }
  return $wcfm_products_manage_form_data;
}, 50 , 2 );

Add this code to your child theme’s functions.php
In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/
