Using getelementbyid in php

Question

I have a question about use the getElementById in php.

$tile = "<script>document.getElementById('selRow0').value</script>";
$height = "<script>document.getElementById('height0').value</script>";
$width = "<script>document.getElementById('width0').value</script>";

Make a SQL query in php

mysql_connect("localhost", "root", "root") or
die("Could not connect: " . mysql_error());
mysql_select_db("partition");
$query = "SELECT `Price` FROM `database` WHERE `Material ID` IN (SELECT `Material_ID` FROM `material` WHERE `Tile` = '$tile') AND  `Width_Height ID` IN (SELECT `Width_Height ID` FROM `width_height` WHERE `Width` ='$width' AND `Height` ='$height');";

It doesn't run the code, why?

@NileshSothiya Why would he? How you would use it? His HTML is completly irrelevant here. — Szymon Toda, Apr 28 '14 at 07:29
@Ultra he can not use script like this, he need to post form to get value. — Nilesh Sothiya, Apr 28 '14 at 07:32
You need to pass the information collected by JavaScript to PHP using form post or AJAX. — Salman A, Apr 28 '14 at 07:35
As tinybyte said, you are mixing..., Cookies, or AJAX could be possible solutions — amd, Apr 28 '14 at 07:42
@user3422462 You obviously do not understand some things. I would suggest that you use some time on learning PHP and Javascript (the difference between them, at least) before continuing. — Sverri M. Olsen, Apr 28 '14 at 07:48

JavaScript use the DOM, php can use it???? – Alex_OX_17 Apr 28 '14 at 07:47
He is not thinking about the DOM. He wants to get some information from the browser to the server; parsing the DOM will not help with that. – Sverri M. Olsen Apr 28 '14 at 07:50
It's so cool to have -2 and still its good answer. – Szymon Toda Jun 13 '14 at 06:57
