line breaks in a textarea

Question

I know when saving a textarea you can use the nl2br   or str replace to change the  n to br tags etc  However what im not sure about how to insert line breaks into a textarea  I cant seem to find much about putting the data back into a textarea with those line breaks   For example I have a form where users can update fields  So the user may enter   foo bar baz   When that is saved to the database it would be saved as   foo lt br   gt bar lt br   gt baz lt br   gt    Now when that user goes back to that form after a page refresh all the fields are automatically populated with their previous data by taking the data from the database   However the textarea shows the br tags as text instead of adding in the line breaks  i also tried changing the br tags to  n hoping the textarea would interpret these as line breaks but no joy  As well as this I also tried escaping etc   So my questions are can this be done  Or more importantly can it be done using HTML PHP  im using smarty   If that isnt possible can it be done using javascript   Examples would be appreciated   thanks for reading

From PHP using single quotes for the line break worked for me to support the line breaks when I pass that var to an HTML text area value attribute

PHP

foreach ($videoUrls as $key => $value) {
  $textAreaValue .= $value->video_url . '\n';
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

HTML/JS

$( document ).ready(function() {
    var text = "<?= htmlspecialchars($textAreaValue); ?>";
    document.getElementById("video_urls_textarea").value = text;
});

I m not sure this is possible but you should try  lt pre gt  lt textarea gt       lt  textarea gt  lt  pre gt

Ahh  it is really simple  just add   white-space pre-wrap    to your displaying element css  I mean if you are showing result using  lt p gt  then your css should be  p     white-space pre-wrap

What I found works in the form is str replace   amp lt br amp gt    PHP EOL   textarea

User · Answer

You could use str replace to replace the  lt br   gt  tags into end of line characters   str replace   lt br   gt    PHP EOL   textarea     Alternatively  you could save the data in the database without calling nl2br first  That way the line breaks would remain  When you display as HTML  call nl2br  An additional benefit of this approach is that it would require less storage space in your database as a line break is 1 character as opposed to   lt br   gt   which is 6

Some wrong answers are posted here  instead of replacing  n to  lt br   gt   they are replacing  lt br   gt  to  n  So here is a good answer to store  lt br   gt  in your mysql when you entered in textarea   str replace   n     lt br   gt      textarea

My recommendation is to save the data to database with Line breaks instead parsing it with nl2br  You should use nl2br in output not input   For your question  you can use php or javascript   PHP   str replace   lt br   gt      n    textarea     jQuery       myTextArea   val     myTextArea   val   replace   lt br   gt      N

Don t do nl2br when you save it to the database  Do nl2br when you re displaying the text in HTML  I can strongly recommend to not store any HTML formatting in the database  unless you re using a rich HTML editor as well  in which case it would be silly not to    A newline  n will just become a newline in the textarea
