Title: conditional ineffective Last modified: September 14, 2023 --- # conditional ineffective * [sacconi](https://wordpress.org/support/users/sacconi/) * (@sacconi) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/) * I decided to add `' €'.'/ sett.'` in this function: * ```wp-block-code $display_price2 = get_the_author_meta( '2_periodo', $post->post_author ). ' ' . get_post_meta( $post->ID, 'function_prezzo_secondo', true ). ' €'.'/ sett.' ; if ( ! empty( $display_price2)) { $display_price2='
'. $display_price2 .'
'; } ``` * But I’m realizing that, doing so, the conditional `if ( ! empty( $display_price2))` is unusefull because the variable `$display_price2` will never be empty. The is a remedy to this?

I tryed to put also `.' € / sett` out of the div but i got printed both a white div and under this “€ / sett.” * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17048626) * Why do you want “€ / sett” outside of the div? Divs are normally block level elements, so added content will typically appear below the div and any margins and padding from the div will separate the two. * If you want “€ / sett” styled differently than other div content but still on the same line, place it within `` tags, which display as inline elements. Assign a class attribute to the span so you can target it with CSS separately from other div content. * Thread Starter [sacconi](https://wordpress.org/support/users/sacconi/) * (@sacconi) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17048636) * I dont want it out of the div, I want the conditional be working * Here you shouldnt see the grid with green lines: [https://test.sacconicase.com/lignano-sabbiadoro-appartamento-al-1-piano-con-terrazzo-spazioso-zona-ufficio-spiaggia-16/#titolo_listino_prezzi](https://test.sacconicase.com/lignano-sabbiadoro-appartamento-al-1-piano-con-terrazzo-spazioso-zona-ufficio-spiaggia-16/#titolo_listino_prezzi) * because both get_the_author_meta and get_post_meta are empty, but “€ / sett ruins the function * [Alan Fuller](https://wordpress.org/support/users/alanfuller/) * (@alanfuller) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17048661) * Sorry, what was wrong with my code? Did you try it? * [Alan Fuller](https://wordpress.org/support/users/alanfuller/) * (@alanfuller) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17048673) * I just spotted you added a space as well so to make the empty work then trim() * ```wp-block-code $display_price2 = get_the_author_meta( '2_periodo', $post->post_author ). ' ' . get_post_meta( $post->ID, 'function_prezzo_secondo', true ); if ( ! empty( trim( $display_price2 ) )) { $display_price2='
'. $display_price2 .' € / sett
'; } ``` * Thread Starter [sacconi](https://wordpress.org/support/users/sacconi/) * (@sacconi) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17048755) * It would have worked (it has worked), but the problem is that now there is no more that space, it is replaced with a ‘ ’ , with a space too, so when I use * ```wp-block-code $display_price2 = get_the_author_meta( '2_periodo', $post->post_author ). ' ' . get_post_meta( $post->ID, 'function_prezzo_secondo', true ).''; if ( ! empty(trim( $display_price2 ) )) { $display_price2='
'. $display_price2 .' € / sett
'; } ``` * I still have this problem (with or without the trim) 🙁 sorry for this changment, I’m trying to adjust the code to the project * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [2 years, 9 months ago](https://wordpress.org/support/topic/conditional-ineffective/#post-17051493) * We’re now discussing the same code snippet in two different topics.
