new line \n in template?

[Manfred62]

Tried to make the source (html) looking cleaner. In the code of a repeater template this doesn't work:

<?php echo "{$page->adresse_detail}<br />\n"; ?>

but this does work:

<?php echo "{$page->adresse_detail}\n<br />"; ?>

Could anyone explain this? I'm on Win7 and XAMMP.

[Macrura]

maybe this?

<?php echo $page->adresse_detail . "<br />\r\n"; ?>

or this?

<?php echo $page->adresse_detail . '<br />' . PHP_EOL; ?>

[Manfred62]

thanks for taking a look at this. Tried both versions but they also don't work. Hmm, strange..

Btw, do you really need both <br/> and \n? Don't they accomplish the same thing (the latter without being output on the screen)?

[Manfred62]

of course there's no need for both. It's only cosmetics in the source.

But I'm wondering, why \n<br /> is working and <br />\n is not?

What does not work with your first line of code? I'm on Windows 7 as well and everything works as expected:

template:

<?php echo "{$page->title}<br />\n"; ?><?php echo "{$page->title}<br />\n"; ?>
<?php echo "{$page->title}\n<br />"; ?><?php echo "{$page->title}\n<br />"; ?>

output in 'view source', in IE, FF and Chrome, all the same:

title<br />
title<br />
title
<br />title
<br />

[Manfred62]

I only get the source without new line (first example):

title<br />title<br />title<br />title<br />

hmm, also tried different browsers. Still wondering, why the second example is working.

Very strange....i'm at a loss.

maybe this will help? http://php.net/manual/en/function.nl2br.php

Take a close look especially at the comments. 

Hope that helps!

thanks for the link.

tested the following:

<?php echo nl2br("$page->adresse_detail\n"); ?>
// html output:
first line<br />next line<br />third line<br />

there's no need for the <br> tag, php does it.

But new line is only working inside a string. For example, this string shows a new line in the source:

<?php echo nl2br("$page->adresse_detail\n "); ?>
// html output:
first line<br />
 next line<br />
 third line<br />
 

always nice to learn something new..

The output of a template is ran through the PHP function trim(), which removes whitespace characters surrounding strings (start and end). \n is one of those characters.

That's right. So if "{$page->adresse_detail}<br />\n" is literally the only thing being output by the template file, then that trailing "\n" will be stripped. But in the context of a larger HTML document, you wouldn't see the "\n" stripped.

Ryan, thanks for the info.
