Newline to <br> in Santizer->textarea

[kalimati]

I am using sanitizer->textarea to sanitize and format the message inputted. I've tried various options including newlineReplacement but have been unable to convert newlines to <br> tags. Although the PHP nl2br function works as expected. Any suggestions?

Thanks.

$sanitizer->text(nl2br($your_text), ['allowableTags' => '<br>']);

That is how I managed. I thought newlineReplacement would do the replacements. It wasn't so as the name of the option suggests. Thanks anyway.

But the text and textarea sanitizers don't allow html tags by default and there is also this comment:

'multiLine' => false, // allow multiple lines? if false, then $newlineReplacement below is applicable

Hopefully this will help show what is happening and what the solutions are. You can either go with the option on line 5 or line 7 although if you go with 5 you might also want to adjust the 'maxLength' option from the default 255 depending on expected content.

Thanks Adrian. I went with Option 7. Works well. I guess my mistake was keeping

'multiLine' -> true

assuming it to be a pre-condition to paragraph formatting.

Is there a reason why multiLine and newlineReplacement are not in the API doc? (but still work)

They are in the docs right here for text():

https://processwire.com/api/ref/sanitizer/text/

but you are right, it is not clear from the docs if these also apply to textarea().
