How can I take the text from a textarea (html) and insert line breaks. Right now, if I input info to send out as an e-mail, it puts all the text on the same line without any line breaks.
Using $_POST['field'] to get the data from the form and sending using PHP mail.
回答1:
use \n for new line, or \r\n for return followed by new line
ie.
<?php
printf("This is the first line. \n");
printf("This is the second line");
?>
ie. to replace
html tag with newline:
str_replace ('<br>' , '\r\n', $_POST['field'])
alternativly set the email you are sending out to be html encoded (add html header)
回答2:
Use nl2br() function. It replaces all newlines within a string with html br tags.
回答3:
In php, replace \n with html br tag,
$newTxt = str_replace("\n",'<br>',$txt)
or nl2br() will serve your purpose.
回答4:
remove stripslashes(), this will work.
