Menu
I have a really simple html / php code. It has only a textarea and a send button.
In the textarea, i have a text what has 3 new lines at the begining of the text. I need those line breaks.
After, when i submitting the form, for some reason, it is chop 1 of the line break at the begining of the text. And when i send it again, it do it again, remove line breaks, while the begining of the content is not a text.
Why is it happening? I tried it with FF, Chrome, Safari, Oprea, IE with the same result.
You can test it with this code:
<?php
if (empty($_POST["operation"])) {
//Init the textarea value if form not submitted
$_POST["message"] = "\r\n\r\n\r\nThis is\r\na multiline text";
}
?>
<!DOCTYPE html>
<html>
<head>
<title>Multiline test</title>
<meta charset="UTF-8" />
</head>
<body>
<form method="post" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
<textarea style="width: 200px; height: 150px;" name="message"><?php echo $_POST["message"]; ?></textarea>
<input type="submit" value="send" />
<input type="hidden" name="operation" value="send" />
</form>
</body>

Browsers ignore the first and last line breaks inside the <textarea> tag. This is because if you wouldn't want any extra line breaks if you write the HTML like this:
<textarea>
Textarea content, all in one line.
</textarea>
The simple solution in this case is to just add one line break before printing the textarea contents.
<textarea style="width: 200px; height: 150px;" name="message">
<?php echo $_POST["message"]; ?>
</textarea>
Also note that you don't need \r\n. Just \n is enough.
