Hi there,

Javascript is a client side scripting language so there is no interaction between the client ( browser ) and the server. However, PHP is a server side scripting language so your browser send a request to the server, the server evaluate and process your request and the send the response to the browser again. In PHP, you can get the value of your input field by using the super global array $_POST and in your case, you can access the variable in your PHP script using $_POST['one'] (i.e. by the name of the field and not the id).

so

txt1 is a textfield

document.getElementByID("txt1").value = "Hello World";

 

how can i do this in php?

$_POST["txt1"]="Hello World" "?"

 

i really dont know sorry if its wrong xD

PHP and javascript are not interchangeable. PHP generates pages. Javascript runs after the page is loaded.

 

how can i do this in php?

$_POST["txt1"]="Hello World" "?"

 

You have to echo the HTML for the txt1 with hello world in it.

 

<?php
$text = "Hello world";
?>
<input type="text" value="<?php echo $text ?>"/>
