Hi, I have a view (nejnizsi-cena-varianty-zazitku, ID 972) for displaying the lowest price from all the prices which are children of parent CPT. I want to conditionally display "free" if the price is 0.

Amount: [wpv-view name='nejnizsi-cena-varianty-zazitku']<br>
Conditional: [wpv-conditional if="( '[wpv-view name='nejnizsi-cena-varianty-zazitku']' eq '0' )"]free[/wpv-conditional]

The code above displays correct amount, but if the amount is zero, it will not show the text "free".

I also use this shortcode for cleaning up the output of view:

function prefix_clean_view_output( $out, $id ) {
  $ids = array( 880,881,972,975 );
  if ( in_array( $id, $ids ) ) {
    $start = strpos( $out, '<!-- wpv-loop-start -->' );
    if (
      $start !== false
      && strrpos( $out, '<!-- wpv-loop-end -->', $start ) !== false
    ) {
      $start = $start + strlen( '<!-- wpv-loop-start -->' );
      $out = substr( $out , $start );
      $end = strrpos( $out, '<!-- wpv-loop-end -->' );
      $out = substr( $out, 0, $end );
    } else {
      $start = strpos( $out, '>' );
      if ( $start !== false) {
        $out = substr( $out, $start + 1 );
        $end = strpos( $out, '<' );
        $out = trim(substr( $out, 0, $end ));
      }
    }
  }
  return $out;
}

Hi, can you inspect the page source and copy + paste the HTML generated for this section?

Amount: [wpv-view name='nejnizsi-cena-varianty-zazitku']<br>

I'd like to see exactly what is generated by your View on the front-end.

Hi, it´s this output if there is any price to show:

Amount: 
	
		0
	
	<br>

If there is no price:
[php]
Amount: <br>
[php]

Okay I can see that there's still some empty space around the output of the View, which is causing the conditional to fail. To fix this, you must eliminate all extra spaces and line breaks from the View's output. Your Loop Output should be one continuous line with no spaces or line breaks, like this:

[wpv-layout-start][wpv-items-found]<!-- wpv-loop-start --><wpv-loop>[wpv-post-field name="wpcf-price"]</wpv-loop><!-- wpv-loop-end -->[/wpv-items-found][wpv-no-items-found]<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>[/wpv-no-items-found][wpv-layout-end]

Notice that I'm using wpv-post-field instead of a types field shortcode. The wpv-post-field shortcode will return the raw data for this field without not any extra markup. Replace "wpcf-price" with the slug of your price field. Use the "wpcf-" prefix, so if your field slug is "the-price" then you should use "wpcf-the-price".

Make sure there is no empty space or empty lines at the beginning or end of the Loop Output editor. Then remove the shortcode [wpv-filter-meta-html] from the Filter and Loop Output Integration Editor, and make sure there is no empty space in this area as well. This should remove all the empty space around the View output, so it should begin to function correctly in your conditional.

Thank you for your help, it works nice.
