preg_split in _filter_url breaks for long html tags

Created on 27 September 2021, over 2 years ago
Updated 23 March 2023, about 1 year ago

Problem/Motivation

Having a really long HTML tag (e.g. < img > with src:data/image...) makes preg_split fail and return false. On PHP 7.4 this throws a warning ("Warning: count(): Parameter must be an array or an object that implements Countable in _filter_url() (line 535 of core/modules/filter/filter.module).") and makes the field render empty, on PHP 8.0 this throws a fatal error.

Steps to reproduce

1) Have a text format that has Convert URLs into links enabled
2) Using that text format, add a node with content like this: https://gist.github.com/kporras07/618b3bf4cd77ff57fcd5034262220e99
3) Visit the node
4) You will get the warning and empty node or the fatal error depending on your PHP version

Proposed resolution

If $chunks is empty, keep $text.

Remaining tasks

    Thanks for the above fix,

    Just hit this with PHP 8.1 / D9.5.5 and search_api, I added fields with phonetic and spellcheck type in the search index, indexed content, it got half way and on some weird content indexing an exception occured as described in this patch declaration
    using this patch until a tagged release comes:

    "3239472 - PHP 8.1 filter when using spellcheck search api field type and phonetic, indexing came up with this TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in _filter_url() (line 539 of core/modules/filter/filter.module": "https://git.drupalcode.org/project/drupal/-/commit/bcd7a66c05d470271f49939cf5e6925892041da3.diff"

  • Automatically closed - issue fixed for 2 weeks with no activity.
