    I tryed putting a conditional in the following function:

    <?php

$posttags = wi-fi;

$post=post;

if (isset($posttags)) {

$wi_fi_esc = '<div class="wi_fi_esc">'. get_the_author_meta( 'wi_fi_esc', $post->post_author ) .'</div>';

}

// Pass all this info to post content
$content = $content . $titolo_prezzo_include . $locazione  .  $commissione . $consumi . $pulizia_inc . $biancheria_inc . $ac_inc .  $titolo_prezzo_non_include . $pulizia_esc . $tassa_soggiorno . $supplemento_animali . $supplemento_culla . $importo_cauzione . $servizio_spiaggia . $suppl_soggiorni_brevi . $biancheria_esc . $asciugamani_esc . $wi_fi_esc . $ac_esc .  $saldo . '<footer class="author_bio_section" >'. $author_details . $titolo_affitti . $periodo_affitti . $titolo_orari . $orari .'</footer>';
}
return $content;
}

    The purpose is to print in a post the variable $wi_fi_esc but only IF in the post target is set the tag (WP taxonomy) whose name is “wi-fi”

    I still havent checked it for real

  • Hi @sacconi

    The variable $wi_fi_esc needs to be declared before use to avoid errors referencing an undefined variable. In the given code, it is necessary to add the declaration of the variable $wi_fi_esc before the if condition.

    $wi_fi_esc = ''; 

if (isset($posttags)) {
    $wi_fi_esc = '<div class="wi_fi_esc">' . get_the_author_meta('wi_fi_esc', $post->post_author) . '</div>';
}

    I think it’s a part of the code I havent written, but there is already: 

    function wpb_author_info_box( $content ) {
 
global $post;
 
// Detect if it is a single post with a post author
if ( is_single() && isset( $post->post_author ) ) {

$posttags = wi-fi;

$post=post;

if (isset($posttags)) {

$wi_fi_esc = '<div class="wi_fi_esc">'. get_the_author_meta( 'wi_fi_esc', $post->post_author ) .'</div>';

}

}

}

// Pass all this info to post content
$content = $content . $titolo_prezzo_include . $locazione  .  $commissione . $consumi . $pulizia_inc . $biancheria_inc . $ac_inc .  $titolo_prezzo_non_include . $pulizia_esc . $tassa_soggiorno . $supplemento_animali . $supplemento_culla . $importo_cauzione . $servizio_spiaggia . $suppl_soggiorni_brevi . $biancheria_esc . $asciugamani_esc . $wi_fi_esc . $ac_esc .  $saldo . '<footer class="author_bio_section" >'. $author_details . $titolo_affitti . $periodo_affitti . $titolo_orari . $orari .'</footer>';
}
return $content;
}

    It makes a sense?

    In your current code, I still feel that the variable $wi_fi_esc is undefined since you didn’t declare it before the if statement. Therefore, inside the HTML in the variable $content, it remains undefined.

    Now I understand. You’re saying that you defined the variable outside of the function.

    I think there are many things to fix in my code. Because the are many $ variables but only one has a conditional. The original full code, that is working, is:

$display_name = get_the_author_meta( 'display_name', $post->post_author );
 
// If display name is not available then use nickname as display name
if ( empty( $display_name ) )
$display_name = get_the_author_meta( 'nickname', $post->post_author );

    I want a different behaviour just for one variable: $wi_fi_esc , this variable is displayed only if in the posts the tag “wi-fi” is set

    For this reason I created

    $posttags = wi-fi;

$post=post;

if (isset($posttags)) {

$wi_fi_esc = '<div class="wi_fi_esc">'. get_the_author_meta( 'wi_fi_esc', $post->post_author ) .'</div>';

}

    But I dont know how to concatenate it with all the other code

    Once you have placed the variable $wi_fi_esc within a condition, it will be necessary to define the variable outside of that condition as an empty variable: $wi_fi_esc=”

    What is the meaning of “$posttags = wi-fi”?

    Ok, but I can write in the same functions 2 times the same variable? One time under conditional, the other time with no conditional?

    Do it : $ wi_fi_esc=”;
    if (isset ($posttags)) {
    $ wi_fi_esc=’

    ‘. get_the_author_meta (‘wi_fi_esc’, $post->post_author) . ”;
    }

    “$posttags = wi-fi” should mean: if the target post has a tag called “wi-fi”. I mean the default wp non hierarchical taxonomy. Or: If I have selected this tag

    (@sacconi)

    ok, and where I can put the div class?

    The original function was: 

    $wi_fi_esc = '<div class="wi_fi_esc">'. get_the_author_meta( 'wi_fi_esc', $post->post_author ) .'</div>';

    look:

    I have made an update to the previous code. Take a look again.

    I see, but the specific tag name “wi-fi” is not defined. ” Only when this specific tag is set, the variable $wi_fi_esc has to output nothing
