打印文本区域的内容不起作用

php:

 if(isset($_POST['submit_']))
 {
    if(isset($_POST['textEditor']) && !empty($_POST['textEditor']))
    {
       echo 'hello';
       $msg = $_POST['textEditor'];
       echo ($msg);
    }
 }

html:

 <input type="submit" name="submit_" value="Add" />
 <textarea name="textEditor" rows="20" cols="60" > </textarea>

I want to print the content of the text area when submit button is clicked. But even when the textarea is non-empty, it prints nothing.

For testing, I printed 'hello', but it still prints nothing that is the second ' if ' statement is not satisfied. I do not understand why does the second ' if ' statement fail !

And if I remove the second if statement, then I get an error:

Notice: Undefined index: textEditor in...

    seems you have texteditor outside of form you need to try like

    <?php
    if(isset($_POST['submit_']))
     {
        if(isset($_POST['textEditor']) && !empty($_POST['textEditor']))
        {
           echo 'hello';
           $msg = $_POST['textEditor'];
           echo ($msg);
        }
     }
    ?>
    <form method="post">
    <textarea name="textEditor" rows="20" cols="60" > </textarea>
    <input type="submit" name="submit_" value="Add" />
    </form>
    

    if form is set already try to check form method="post" or print_r($_POST); in php code
