[Resolved] Calculating the Length of Post Titles and of Custom Fields

I want to display the lengths of some Post Titles and of Custom Fields.

I've found some threads about calculating the length of a custom field within a conditional, but I'm afraid I wasn't able to convert that answer into a simple display of the lengths.

Thanks

Hello. Thank you for contacting the Toolset support.

Well - do you mean that you want to display the total number of character value? Where exactly you want to display the total character count value? in admin or frontend?

I want to display the length of the Title of a post, and the length of a Custom Post Type - both in the front-end.

[Minesh]

when do you say length in what format you want to calculate it - in characters or words?

[alexG-4]

In characters

Well - can you please try to add the following shortcode to your current theme's functions.php file.
OR
You can then add the custom shortcode to Toolset's custom code section:
=> https://toolset.com/documentation/adding-custom-code/using-toolset-to-add-custom-code/

function func_show_char_count( $atts ) {
 global $post;

If($atts['type']=="title") {
      return strlen($post->post_title);
}else if($atts['type']=="post_type"){
   return strlen($post->post_type);
}
   return FALSE;
}
add_shortcode( 'show_char_count', 'func_show_char_count' );

You can call the shortcode as given under:
To display Title character count:

[show_char_count type="title"] 

To display Post Type character count:

[show_char_count type="post_type"]

Thanks, Minesh

The "title" version works perfectly, but I'm confused about the "post_type" version and I'm not familiar enough with PHP - especially in a WP environment - to be able to decode what you've done.

I'll want to use the short-code with various custom fields - for example 'basic-topic'.

With that, I've tried

[show_char_count type="basic-topic"]

and

[show_char_count type="wpcf-basic-topic"]

But neither works.

BTW - this is all within a View loop - in case that makes a difference.

Well - Ive changed the shortcode so that it supports the custom field.

function func_show_char_count( $atts ) {
 global $post;
 
If($atts['type']=="title") {
      return strlen($post->post_title);
}else if($atts['type']=="post_type"){
   return strlen($post->post_type);
}else if($atts['type']=="field"){
  $field = $atts['name'];
   $value = get_post_meta($post->ID,"wpcf-".$field,true);
   return strlen($value);
}

   return FALSE;
}
add_shortcode( 'show_char_count', 'func_show_char_count' );

And you can call it as given under:

[show_char_count type="postfield" name="basic-topic"]

Hi Minesh

Thanks! That works. And I see now that my original question was not clear enough about what I needed, so thanks for your patience.

I think this is a useful facility, so if it get written up as a "Solution", please note that the usage should include type="field", rather than type="postfield".
