Hi all,

i would like to have reviews of a MINIMUM (not max) length of 180 characters.

Anyone knows a plugin that can help me?

Hi,

the only plugin I ever heard about for this is https://wordpress.org/plugins/minimum-comment-length/ from Yoast.

However it appears to be working only with the default wordpress comment function is used, if you use a walker function like we do, apparently it doesn’t work.

Personally I haven’t tested it.

Let us know how you went,

Thanks

Ciao,
add the following code to your functions.php inside your child theme’s folder
```
add_filter( 'preprocess_comment', 'commentominimo' );
   
 function commentominimo( $commentdata ) {
      $commentominimo = 180;
   
      if ( strlen( trim( $commentdata['comment_content'] ) ) < $commentominimo ){
      wp_die( 'La recensione deve avere un minimo di ' . $commentominimo . ' caratteri.' );
      }
  
      return $commentdata;
      }
```

Hi,

Simone said he tested it and it was working for him, are you sure you are adding it correctly?

Let us know,

It is a tested code, so if you’re pasting it in the right way (in the functions.php, inside your child theme’s folder), it must work 🙂

You can test it here

OK IT WORK PERFECTLY! thanks a lot.

i would like to redirect the user back to the listing page with two options:
1- after a couple of seconds he is automatically redirected
2- with a “back” button

i modified the working php code but it seems not to work…
```
add_filter( 'preprocess_comment', 'commentominimo' );
   
 function commentominimo( $commentdata ) {
      $commentominimo = 180;
   
      if ( strlen( trim( $commentdata['comment_content'] ) ) < $commentominimo ){
      wp_die( 'La recensione deve avere un minimo di ' . $commentominimo . ' caratteri.' );
      
      header("Location: {$_SERVER['HTTP_REFERER']}");
      exit;
      }
     return $commentdata;

      }
```
Thanks

Hi, im not sure the page sends a referrer, thats why it isn’t working. You can try with a back button, as explained here
