  1. Thank you so much for helping me The part that I did not understand and had problem with was "the idea is that the function to calculate the area to be used inside the function perimeter, so that the perimeter function handles all printing."
  2. this is what I mean <?php if (isset($_POST['calc'])) { $length= $_POST['length']; $width= $_POST['width']; echo "length:" . $length. "<br><br>"; echo "width:" . $width. "<br><br>"; I am not allowed to give the $length = 10; $width = 5; It's like this anyone that going to see this page can give what ever length and what ever width that they want in the text-box and than enters the calculate button and gets the length, the width that he/she gave and the area and the perimeter that was calculated.
  3. Create a method called "perimeter ()" that calculates the perimeter of a rectangle. The function to receive the two parameters "long" and "width" of a form. perimeter shall then be printed on the page when the user presses a button titled "CALCULATE". Create a method called "Area ()" that calculates the area of a rectangle. Call the method "Area ()" method from within "perimeter ()", submit length and width as an argument to the method "Area ()" and use these to calculate the area. Modify Approach "perimeter () "so that it prints the perimeter and area when the user presses the button "CALCULATE". No printing will be done in Approach "Area () " It's like this that the person that visits this page is going to input any number and that presses the button calculate and than the output is like: length: the number given by the person width: the number given by the person perimeter: answer area: answer
  4. I am not allowed to give the length and the width. and I tried not to give the length and width but it did not work. It's not giving me the area and perimeter
  5. the idea is that the function to calculate the area to be used inside the function perimeter, so that the perimeter function handles all printing. This is what I've done but it's not the same as what I have mentioned above. What Should I do? This is what I want to do Create a method called "Area ()" that calculates the area of a rectangle. Call the method "Area ()" method from within "perimeter ()", submit length and width as an argument to the method "Area ()" and use these to calculate the area. Modify Approach "perimeter () "so that it prints the perimeter and area when the user presses the button "CALCULATE". No printing will be done in Approach "Area () " <body> <h1>PHP-sida 4</h1> <form action="php4.php" method="post"> <p>Längd: <input type="text" name="length" size="20" /></p> <p>Bredd: <input type="text" name="width" size="20" /></p> <p><input type="submit" value="CALCULATE" name="calc" /></p> </form> <?php if (isset($_POST['calc'])) { $length= $_POST['length']; $width= $_POST['width']; echo "length:" . $length. "<br><br>"; echo "width:" . $width. "<br><br>"; function perimeter($length, $width) { return 2* ($length+ $width); } $perimeter= perimeter($length, $width); echo "perimeter:" . $perimeter. "<br>", "<br>"; function area($length, $width) { return $length* $width; } $area = area($length, $width); echo "area:" . $area ; } ?> </body>
