I'd like to incorporate PHP into still <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <p class="subhead">High School 4.0 GPA Calculator<div id="content"> <p> <form id="gpa_calculator" action="gpa.php" method="post" name="gpa_calculator" target="_self"> <!-- the above string was on the website --> <fieldset> <table border="0" cellspacing="2" cellpadding="0"> <tr align="right"> <td width="133">Number of Courses:</td> <td><input type="text" name="number_of_courses" value="6" size="4" /></td> </tr> </table> <p><input type="submit" name="submit" value="Submit" /></p> </fieldset> <p></p> <fieldset> <table border="0" cellspacing="2" cellpadding="0"> <tr> <td align="center" width="90"></td> <td align="center" width="90">Grade</td> </tr> <tr> <td align="center" width="90">Course 1 : </td> <td align="center" width="90"> <select name="grademenu2"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> <tr> <td align="center" width="90">Course 2 : </td> <td align="center" width="90"> <select name="grademenu2"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> <tr> <td align="center" width="90">Course 3 : </td> <td align="center" width="90"> <select name="grademenu3"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> <tr> <td align="center" width="90">Course 4 : </td> <td align="center" width="90"> <select name="grademenu4"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> <tr> <td align="center" width="90">Course 5 : </td> <td align="center" width="90"> <select name="grademenu5"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> <tr> <td align="center" width="90">Course 6 : </td> <td align="center" width="90"> <select name="grademenu6"> <option value="1" selected>A</option> <option value="2">B</option> <option value="3">C</option> <option value="4">D</option> <option value="5">F</option> </select> </td> </tr> </table> <p><input type="submit" name="submit" value="Submit" /></p> <table border="0" cellspacing="2" cellpadding="0"> <tr align="right"> </tr> <tr align="right"> <td>Current GPA:</td> <td align="left"><b>0.000</b></td> </tr> </table> </fieldset> <p></p> -
Having trouble with a HS GPA(4.0 scale) Calculator

Perfect example would be http://advising.ucsc.edu/student/gpa.php but for High School... simpler, without credits, GPB, and grade points -
I understand the basics of PHP enough to make forms and such and even a little to do calculations, but I've run into a little bit of a snag. What seemed like it would be extremely simple has advanced to a little more than I could chew. I can't figure out how to set a letter(grades, i.e. a b c d f) equal to its corresponding value(a=4, b=3, c=2, d=1, f=0). Simple for most of you... I can't seem to put it in the right order nor figure out a way to successfully calculate it with all the properties for the GPA. If you aren't aware the way to calculate a GPA is you have a set number of classes(1-6) and each class you get a grade, ABCDF, add the variables together then divide by the number of classes. It is set like this: a=4 b=3 c=2 d=1 f=0 x=classes(1-6) GPA= grade from each class added together/x Trouble is I have to make a html dropdown list stating 1-6 then having it list several forms underneath(# of forms depends on dropdown list) and having each grade be entered as the letter itself and have a calculate button that will add the values then divide by the number of classes... I don't know how to retain the # of classes on the same page. I have no idea how to make it organized but if you have ideas, please let me know. I have been trying for hours on this, I really need tips and examples and solutions. I'm a n00b at this web design in general and I know this is a large endeavor but I hope to learn a lot from it. Thank you very much for helping/considering to help.
