textarea is not posted in $_POST

问题:

I have a simple form with a textarea field inside it and when posting, the textarea is not posted to the target page. I have tried many solutions on the web but none of them worked. Any idea how to fix it ?

HTML:

<form action="new_page.php" method="post" id="userform">

    <p>Content:<br />
    <textarea name="content" rows="15" cols="80" form="usrform">Enter your text</textarea>
    </p>
    <input type="submit" name="submit" value="Create page"/>
   </form>

PHP in new_page.php:

$content = htmlspecialchars($_POST["content"]);
echo $content;

回答1:

Remove form="usrform" from your textarea and your code will work.

[or]

Renaming usrform on your textarea to userform will also work.

Quick fix

Remove the form="usrform" from the textarea

OR,

change it to form="userform" to match the ID you have set on your form

So, what is the form attribute?

The form attribute (introduced in HTML5) allows you to specify exactly which forms the current element should be related to. You can add multiple values by separating them with a space, indicating the element belongs to multiple forms.

This allows you to have form elements outside of the form itself. If you assign the forms ID to the form attribute, it will be submitted in the forms data.

NB This is not supported in IE

Try this:

    Just remove form="usrform" from textarea && your code will work.

    <form action="new_page.php" method="post" id="userform">

        <p>Content:<br />
        <textarea name="content" rows="15" cols="80">Enter your text</textarea>
        </p>
        <input type="submit" name="submit" value="Create page"/>
       </form>

You can get value from textarea like this.

<?php    
$content = htmlspecialchars($_POST["content"]);
    echo $content;
?>

Thanks!
