将数据从textarea保存到HTML中的数据库

Question

I´m looking for a way to save data from an input field to database.

Now, on the HTML-page is a simple textarea -Field. If the user presses the button to save the data a javascript function executed.

This javascript function get´s the data from the textarea with this statement:

test = $('#test1').val();

And then it will be given to the php-function with this statement.

 $.get(url+"test/saveTest/"+test, function (o){ 
        //Do something
  });

It works, but if I add a linebreak in textarea it will be lost.

Anybody nows a solution? Or an alternative to textarea-input field?

Answer 1

Instead of $.get I would recomend to use $.post or $.ajax because $.get is like the name says to get data not to post data.

Ajax example

$.ajax({
    type: "POST",
    url: url + "test/saveTest/",
    data: {'test': test},
    dataType: "json",
    success: function (){
        // do what you want when the submit was successfully
    },
});

PHP

$test = json_decode($_POST['test']);

For the problem with displaying the line breaks you can output your database field by using

echo nl2br(DATABASE FIELD);
