You want to do this in php? It seems more like a javascript questionPHP may be a better choice nowadays. JS is counted as one more file to load.
For example if height = 2200 and width = 1000 then 2 x sides 2200 x 570, 1 x top 964 x 570, 1 base 964 x 570.
... lots of coding to do with different sizes
I want to be able to go on the page type in the 2 inputs hit a button and the results show either in the page or an i frame.
<input type=”text”name=”height”><br>
<input type=”text”name=”width”><br>
<input type=”submit”>$adjusted_width=$width – 64;
$height=”$height”;
Echo” <p>Sides (2) $height x 570;,<br>
Top (1) $adjusted_width x 570<br>
Base (1) $adjusted_width x 570 </p>”;
