Hiding text in the email sent by CF7 if a field is empty

It will be available in the next version.

@takayuki Miyoshi – great news. Thanks so much for doing this.

I wrote a quick solution using current available cf-7 hooks: basically adding special characters then deleting what’s in between those special characters. It works- it isn’t pretty, makes for rather busy email templates, but it works.

I added the following to functions.php:

<br />
add_filter( 'wpcf7_special_mail_tags', 'empty_field_characters',10,2);</p>
<p>function empty_field_characters( $output,$name ) {<br />
	$name=trim(ltrim($name,'_'));<br />
	if(empty($_POST[$name])){<br />
		$output='{}';<br />
	} else $output=' ';<br />
	return $output;</p>
<p>}</p>
<p>//filter to remove any p tags that contain the special characters for an empty field</p>
<p>add_filter( 'wpcf7_mail_components', 'remove_blank_lines' );</p>
<p>function remove_blank_lines( $mail ) {<br />
	if ( is_array( $mail ) && ! empty( $mail['body'] ) )<br />
		$mail['body'] = preg_replace('/<span\b[^>]*>{}(.*?){}<\/span>/i', '', $mail['body'] );<br />
	return $mail;<br />
}<br />

I then marked up the email template, each line as follows:

<br />
<p><span>[_address_destination]Street Address: [address_destination][_address_destination]</span></p><br />

In this fashion, if the field is empty, curly braces are inserted after and before the span tags. This is then removed by the preg_replace function.

As I said, not pretty, but it gets the job done!

Hi!

Is this function now available in CF7?

Or any other solution?

Kind regards
Arndt

RE: Is this function now available in CF7?

Yes – tick the “Exclude lines with blank mail-tags from output??” option below Mail > Message body: in the CF7 interface.

sometimes its very easy. ??

Ok, but i have still the problem, that i now don’t have the empty line into my mail, but the heading is still visible. i use code like this:

TEST
[text text-617 placeholder "Testfeld"]

Is there any solution to hide the headline too?
