Read_time modifier working with bard that has sets?

[austriker27]

Hello!

Has anyone gotten the read_time modifier working with bard when you have sets?

I found this post for awhile ago but its not working for me (post is from V2):
https://statamic.com/forum/2970-read-time-from-bard-fieldtype

When I try this in antlers:

{{ blog_content | flatten | join | strip_tags | read_time:180 }} min read

I get this error:
Error: Array to string conversion

Inside the CMS, at the bottom of the bard field it does show the read time when Im using sets. Not sure if this is helpful but I looked at the source code and its using this package: https://www.npmjs.com/package/read-time-estimate

@austriker27 I ran into the same issue and ended up writing a modifier that would try to flatten everything. But it's far from working well, so I'd prefer a core fix.

I've opened an issue for you.

<?php

namespace App\Modifiers;

use Statamic\Modifiers\Modifier;

class TextOnly extends Modifier
{
    /**
     * Modify a value.
     *
     * @param mixed  $value    The value to be modified
     * @param array  $params   Any parameters used in the modifier
     * @param array  $context  Contextual values
     * @return mixed
     */
    public function index($value, $params, $context)
    {
        $value = array_flatten(json_decode(json_encode($value), false));

        $fields = ['lead', 'title', 'description', 'content'];
        $text = '';
        foreach ($value as $item) {
            foreach ($fields as $field) {
                if (isset($item->$field) && is_string($item->$field)) {
                    $text .= $item->$field . ' '; 
                }
            }
        }

        return strip_tags($text);
    }
}

I’m using the modifier this way in my Antlers template:

{{ newsbuilder | text_only | strip_tags | read_time }} min read.

Nice, this is useful until its available in core. Thanks for sharing!

@mynetx I tried this approach but am getting "0" min read. Sorry I don't really know PHP so I'm not sure where my issue is. But I created the modifier TextOnly and added blog_content (because thats my bard field name) to the following line:

$fields = ['lead', 'title', 'description', 'content', 'blog_content'];

Then used it like this in the HTML:

{{ blog_content | text_only | strip_tags | read_time:180 }} min read

Am I missing anything? Thanks!

@austriker27 It should not be the name of the Bard field, but the name of the content field inside any of your sets. And the code does not support nested sets. I’m thinking about a more generic solution as we speak.

Gotcha gotcha! Thanks, I've got it working now! Wooohooo!

@austriker27 Just came up with a slightly modified version that will walk into nested structures. Maybe that helps?

<?php

namespace App\Modifiers;

use Statamic\Modifiers\Modifier;

class TextOnly extends Modifier
{
    /**
     * Modify a value.
     *
     * @param mixed  $value    The value to be modified
     * @param array  $params   Any parameters used in the modifier
     * @param array  $context  Contextual values
     * @return mixed
     */
    public function index($value, $params, $context)
    {
        $value = array_flatten(json_decode(json_encode($value), false));

        return $this->_walk($value);
    }

    protected function _walk($value)
    {
        $fields = ['lead', 'title', 'description', 'content', 'text', 'copy'];
        $text = '';
        foreach ($value as $item => $value) {
            if (is_string($value)) {
                if (in_array($item, $fields)) {
                    $text .= $value . ' ';
                }
                continue;
            }
            if (is_array($value) || is_object($value)) {
                $text .= $this->_walk((array) $value);
            }
        }
        return strip_tags($text);
    }
}

Not sure what the gents think but in an ideal world I'd love if you could just do this... (the read_time modifier would know about Bard and how to make it into something that's usuable)

{{ blog_content | read_time:180 }} min read

[mynetx]

That’d be my ideal world, too… 👼🏻
