如何通过ajax将textarea中的换行符传递给PHP

Question

Im using the back end of wordpress to allow the client to fill in a form and send the content of a text area in an email.

My problem here is that when I click send, the string from the text area converts to Line1%0ALine2%0ALine3 (as a result of encodeURIComponent()) and posts that over to my PHP funciton. When this is sent out in the email thats literally what I get.

I know I need to decode / encode this in some way and I think Im nearly there.

So far my JS looks like this.

tinyMCE.triggerSave();
var messagetext = jQuery('textarea#emailMessage').val();
var newEmailForm = [];
var email = jQuery('input.email').val();
var title = jQuery('input.title').val();
var emailMessage = encodeURIComponent(messagetext);
newEmailForm.push([email,title,emailMessage]);

var datastring = {
        newEmailForm: newEmailForm,
        properties: properties
    };

jQuery(function(){
        jQuery.ajax({
            type:'POST',
            data:{
                action: 'elegantSendEmail',
                datastring: datastring
            },
            url: ajaxurl,
            success: function(data){
                alert(data);
            }
        })
    })

Using encodeURIComponent() posts the message text like this: Line1%0ALine2%0ALine3

My PHP Looks like.

function elegantSendEmail() {

  $to = $_POST['datastring']['newEmailForm'][0][0];
  $title = $_POST['datastring']['newEmailForm'][0][1];
  $messagetext = $_POST['datastring']['newEmailForm'][0][2], true);
  $properties = $_POST['datastring']['properties'];

  //Send the email and get a report back
  $sent = elegeantSend($to,$messagetext,$properties);

}

I just dont know how to convert the string into either <br> or etc.

TIA

You can use rawurldecode function It will decode in php which is encoded with encodeURIComponent()
