only show custom tabs if not empty?

Sorry I missed the message to the post:

Hi,
I added a custom function to add custom product tabs for woocommerce, that grab content from “advanced custom fields” plugin. It ist working fine. Problem is, I want to hide the complete tab if empty.

I found several tutorials that are hiding tabs if empty. Problem is my shop has a lot of products and all infos are already added in advanced custom fields, so i have to go with this solution.

how can I add this function to my code above?

No one?!

Hi @christianslater, you may try add below code to functions.php:

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab_1' );
function woo_new_product_tab_1( $tabs ) {

if( !empty(get_field( 'downloads' )) ){
  $tabs['downloads'] = array(
    'title' => __( 'Downloads', 'woocommerce' ),
    'priority' => 40,
    'callback' => 'show_downloads'
  );
}

return $tabs;
}

function show_downloads() {
  echo get_field( 'downloads' );
}

Hi, thanks for your reply!

I tried but it gives me a complete blank page on product page…

Any Idea how to solve this?! pease ??

“Prior to PHP 5.5, empty() only supports variables; anything else will result in a parse error.”
https://php.net/manual/en/function.empty.php

OK, as I am no PHP expert. Is there any other solution?

It looks like your issue is unique so it will need some custom php code.

If your php version is <5.5, then terrytsang’s solution may be failing with the empty() function, if so it needs rewriting like this:

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab_1' );
function woo_new_product_tab_1( $tabs ) {
  $var = get_field( 'downloads' );
  if( !empty($var) ){
    $tabs['downloads'] = array(
      'title' => __( 'Downloads', 'woocommerce' ),
      'priority' => 40,
      'callback' => 'show_downloads'
    );
  }
  return $tabs;
}

function show_downloads() {
  echo get_field( 'downloads' );
}

I’m sorry I can’t test it because I don’t have the other components that you have in your system.

Without php skills you may need to hire someone:

thanks. works perfectly!

Hi lorro,
thanks again for your help. It works perfectly. I have another question. I want to add another custom field in the same tab. So If I input another Video it shows under the first one.

How can I add the custom field “einbau_video_2” to that code?

If I just add the custom field to the echo section is is showing, even if there’s no video

function show_video() {
  echo '<div class="video-container">';
echo get_field( 'einbau_video' );
echo '</div>';
  echo '<div class="video-container">';
echo get_field( 'einbau_video_2' );
echo '</div>';}

This is my actual code.

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab_2' );
function woo_new_product_tab_2( $tabs ) {
  $var = get_field( 'einbau_video' );
  if( !empty($var) ){
    $tabs['video'] = array(
      'title' => __( 'Video', 'woocommerce' ),
      'priority' => 20,
      'callback' => 'show_video'
    );
  }
  return $tabs;
}

function show_video() {
  echo '<div class="video-container">';
echo get_field( 'einbau_video' );
echo '</div>';
}

Any help is appreciated.

function show_video() {
  $field = get_field( 'einbau_video' )
  if (!empty($field)) {
    echo '<div class="video-container">';
    echo $field;
    echo '</div>';
  }
}

Again I am unable to test it. You can use var_dump($field); to find out exactly what is in the $field variable.

Thanks again,

I think thats the right way.

How can I add “show_video_2” to the callback

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab_2' );
function woo_new_product_tab_2( $tabs ) {
  $var = get_field( 'einbau_video' );
  if( !empty($var) ){
    $tabs['video'] = array(
      'title' => __( 'Video', 'woocommerce' ),
      'priority' => 20,
      'callback' => 'show_video'
    );
  }
  return $tabs;
}

that’s what I got so far:

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab_2' );
function woo_new_product_tab_2( $tabs ) {
  $var = get_field( 'einbau_video' );
  if( !empty($var) ){
    $tabs['video'] = array(
      'title' => __( 'Video', 'woocommerce' ),
      'priority' => 20,
      'callback' => 'show_video'
    );
  }
  return $tabs;
}

function show_video() {
  echo '<div class="video-container">';
echo get_field( 'einbau_video' );
echo '</div>';
}

function show_video_2() {
  $field = get_field( 'einbau_video_2' );
  if (!empty($field)) {
    echo '<div class="video-container">';
    echo $field;
    echo '</div>';
  }
}

$tabs['video']['callback'] = 'show_video_2';

mhm sorry I don’t understand. I want to show “einbau_video_2” in the same tab just below “einbau_video”. Where do I have to put this code?

Sorry for my dumb question…

Oh, forget my last then. A tab can have only one callback function, so everything you want the tab to show will have to be in show_video(). Putting the two together:

function show_video() {
  // video 1
  echo '<div class="video-container">';
  echo get_field( 'einbau_video' );
  echo '</div>';
  // video 2
  $field = get_field( 'einbau_video_2' );
  if (!empty($field)) {
    echo '<div class="video-container">';
    echo $field;
    echo '</div>';
  }
}
