HTML
<p id="a" name="a"></p>
Javascript
document.getElementById("a").innerHTML=price;
If price is a variable how do I make a php variable that is = to the result that is placed in the HTML of id "a" i?
$price = $_POST['a'];
when echoed this variable comes up blank, and yes I do have a form set up that is handled by a PHP page.
That's not how forms work.
The browser will only send values of form controls (<input>
, <select>
, <textarea>
) to the server.
It won't send values of arbitrary named elements. (in fact, that name="a"
is invalid HTML)
Instead, you should use an <input type="hidden" name="a" value="" />
, and set the value
attribute of this <input>
tag to the value you want PHP to get.
I guess, you want only to change the values in HTML elements. For that you need a XML parser (i.d). I think shamittimar's post may help you. He does exactly what you want.
