Go to solution Solved by Nayr438,

 

I would write to a text file then watch it.

 

On the web side of things. 

<!doctype html>
<head>
  <title>Example</title>
</head>

<?php
if (isset($_POST['form_submitted'])) {
    file_put_contents('webInput', $_POST['textInput']."\n", FILE_APPEND);
}
?>

<body>
    <form action="index.php" method="POST"> 
        <div> Text Input: <input type="text" name="textInput"> </div>
        <input type="hidden" name="form_submitted" value="1" />
        <input type="submit" value="Submit">
    </form>
  
</body>
</html>

 

Then in a terminal, do something like this. 

watch -n2 tail -5 /path/to/htdocs/webInput

 

In this example we are writing to "webInput" then reading last 5 lines every 2 seconds in a terminal.

You need some kind of listener that reads the output from the log or database.

So the input you type in has to be stored somewhere and then you run a command in the terminal to read it.

 

You can use exec or passthru, but it opens up a world of security and permission issues, especially when you make it accept outside user input.

These examples probably wont work unless you have setup permissions for it or you have your web server configured incorrectly. 

exec("wall ".$_POST['textInput']);

  

passthru("echo ".$_POST['textInput']." >> /dev/pts/1")

Hi, so I want to know how to take an input from  

<input>

and output it on my Raspberry Pi terminal as an  

echo

response. How would I do that?

As Someone with the username “</TheCoder2019_”, my coding skills are atrocious.

Here are my specs:

GTX 1060 OC 3GB or Intel UHD 630

16GB (2x8) Cosair Vengeance LPX CL16 - 2400MHz

GAMDIAS Argus M1

 

An old friend of mine - Intel stock cooler (temps through the roof like 60 C under load)

 

 

Linux Apps you NEED!

tmux

dhcpd

git

<?php 

echo "<input type="text">";

you probably want to use form tag beforehand.
