Regex Preg Replace HTML

Question

Please consider the following paragraph...

{{if|service_name=Service}}
  Hello this is the Service text
{{endif}}

This is the format that I allow my users to place custom conditional variables inside contract text. This means that if the service matches "Service", the text will show. I achieve this replacement functionality with the following....

$text = preg_replace("/{{if\|service_name=$service}}\s*(.*?)\R{{endif}}/s", "$1", $text);

This works great, right up until CKeditor is used on the contract text field, and my clients new lines are wrapped in  tags.

So the above works, but this does not..,

<p>{{if|service_name=Service}}</p>

<p>Hello this is the Service text</p>

<p>{{endif}}</p>

I have placed an example here... https://www.phpliveregex.com/p/pEE

Can anyone shed some light on my issue?

1) Use another regex tester to test multiline strings as whole strings. 2) Remove \R since there is no line break between  and {{endif}} 3) Do not use U modifier that switches greediness. See regex101.com/r/kKt2M6/1 — Wiktor Stribiżew

So what is the result you expect? Note that you cannot "skip" the  tags when matching, you will have to remove them with some str_replace(['', ''], '', $res) or similar option (or strip_tags) after extraction. — Wiktor Stribiżew

@WiktorStribiżew Thank you. It was the \R newline that was tripping it up. Please add as an answer and I will accept :-) — Collins

The \R construct matches any line break sequence, and there is no line break between  and {{endif}}.

Your regex may be quick-fixed as

'~{{if\|service_name=Service}}\s*(.*?)\s*{{endif}}~s'
                                      ^^^

The \s* will match any amount of any whitespace (add u modifier after/before s if you may have any Unicode whitespace in the string).

See the regex demo.

Turn it off then, simple!

CKEDITOR.config.autoParagraph = false;

Nope, need the editor for all sorts of formatting options.

delboy1978uk Over a year ago

it's just auto paragraphs you're turning off, not all formatting, give it a try at least

Yeah that would be good, but the chances are they are going to use all sorts of other html in these areas, unordered lists, tables etc. I need something a bit more resilient. Thanks though

That should be fine though, I thought it was only HTML generated by CKEditor that the user did not actually input that you were trying to get rid of, I would presume any markup the user adds would be fine. Why not just try it?
