将 textarea 中的文本插入 MySQL 数据库而不丢失格式

Question

I am trying to add text from a textarea on my site into a MySQL database.

Below is the PHP code that is adding the text to the database.

if (isset($_POST['text']))
{
    $text = sanitizeString($_POST['text']);
    $text = preg_replace('/\s\s+/', ' ', $text);

    $query = "SELECT * FROM profiles WHERE user='$user'";
    if (mysql_num_rows(queryMysql($query)))
    {
        queryMysql("UPDATE profiles SET text='$text' where user='$user'");
    }
    else
    {
        $query = "INSERT INTO profiles VALUES('$user', '$text')";
        queryMysql($query);
    }

}
else
{
    $query  = "SELECT * FROM profiles WHERE user='$user'";
    $result = queryMysql($query);

    if (mysql_num_rows($result))
    {
        $row  = mysql_fetch_row($result);
        $text = stripslashes($row[1]);
    }
    else $text = "";
}

$text = stripslashes(preg_replace('/\s\s+/', ' ', $text));

And below is the code of the form.

<textarea name='text' cols='40' rows='3'>$text</textarea><br /> 

But when the data is inputted, it shows it in the database correct but not showing it displayed properly. See the images below:

The text that is entered

How the text is displayed on the page

How the text is in the database

This is the PHP code that displays the text on the page.

$result = queryMysql("SELECT * FROM profiles WHERE user='$user'");

    if (mysql_num_rows($result))
    {
        $row = mysql_fetch_row($result);
        echo stripslashes($row[1]) . "<br clear=left /><br />

Hope you can help!!

EDIT: added extra php code

Answer 1

Your text, unless you're using a rich-text editor, such as Mark-down (as here on Stackoverflow), is styled by your CSS, not by the contents of the textarea itself.

If the problem is preservation of new-lines, then you could run the string through the nl2br($text) function before storing in, or retrieving from, the database.

I'd suggest on retrieval would be better, but that's just my opinion (and I can't offer any evidence to back it up).

Answer 2

Or you can use

echo nl2br($test);
