Is it possible to write for the alt attribute of images in the template?

Question

MODX

Tell me how to register placeholders from the SEOPRO package for the alt attribute of images,
alt="" so for some reason it doesn't work

Answer 1

If you register in the template, it works, I just checked it. Perhaps you display it in the placeholder of the snippet (I haven't tried it about the placeholder in the snippet).

Answer 2

it’s in the placeholder of the snippet that I want to display, it doesn’t display ... who will advise what to do

Answer 3

As an option create a snippet like this -

<?php
$result = $modx->query("SELECT * FROM modx_seopro_keywords WHERE id=".$id);
if (!is_object($result)) {
   return '';
}
else {
   $row = $result->fetch(PDO::FETCH_ASSOC);
   return $row["keywords"];
}

Save, name for example - "keywords" and call:
