This question already has an answer here:
I am using nl2br function with str_replace as follows:
$data = (!empty($_POST['content']))?nl2br($_POST['content']):null;
$data_fix = str_replace(array("", "
"), '', $data);
When I insert data into database next lines automatically receives a <br>. Okay fine. To 95% extent this is what I want. But if there is no character entered after the next line in <textarea> it still enters a <br>.
Example:
What I want:
Hello Stackoverflow!<br>I am new here.
(new line space eliminated)
What I get:
Hellow Stactoverflow!<br>I am new here.<br>
(new line space inserted)
Please help me solve this!
</div>
trim() function will prevent adding extra <br> which are not needed if there is no text entered in or after the next line!
Simply replaced
$data = (!empty($_POST['content']))?nl2br($_POST['content']):null;
With
$data = (!empty($_POST['content']))?nl2br(trim($_POST['content'])):null;
And it did the job! But trim() should be after the nl2br() otherwise it won't work!
