How to remove carriage returns from output of string?

Question

I am using wordpress as a CMS and trying to allow user fields to be input to populate the info windows in a Google Map script. I am using this to select the id and pull in

Answer 1

I always use this to get rid of pesky carriage returns:

$string = str_replace("\r\n", "\n", $string); // windows -> unix
$string = str_replace("\r", "\n", $string);   // remaining -> unix

Answer 2

I don't fully understand your exact problem, but the answer to the title of your question is quite simple:

$snip = str_replace('.', '', $snip); // remove dots
$snip = str_replace(' ', '', $snip); // remove spaces
$snip = str_replace("\t", '', $snip); // remove tabs
$snip = str_replace("\n", '', $snip); // remove new lines
$snip = str_replace("\r", '', $snip); // remove carriage returns

Or a all in one solution:

$snip = str_replace(array('.', ' ', "\n", "\t", "\r"), '', $snip);

You can also use regular expressions:

$snip = preg_replace('~[[:cntrl:]]~', '', $snip); // remove all control chars
$snip = preg_replace('~[.[:cntrl:]]~', '', $snip); // above + dots
$snip = preg_replace('~[.[:cntrl:][:space:]]~', '', $snip); // above + spaces

You'll still need to use addslashes() to output $snip inside Javascript.

Answer 3

Try JSON-encoding it, I always do that when I send data from PHP to Javascript. It solves most encoding issues, including newlines.

Answer 4

if you need to remove new line symbols of all types (in utf8)

$dataWithoutCarrierReturn = preg_replace('/\R/', '', $inData);

Answer 5

Use WP's own esc_js(), which will escape quotes and line breaks for JavaScript strings.

Answer 6

Since you're putting this into Javascript, you'll need to escape it for javascript strings. addslashes() should do the trick.
