    copied!<p>Trying to create a GPA Calculator. I have a form that submits to a php file and then stores all data from the form in a php array(). The calculator works great until I enter the same value. I think this wont make sense until I show some pictures:</p> <p>Here is the problem in an image: </p> <p><img src="https://i.stack.imgur.com/id7kF.png" alt="Error Scenario"></p> <p><img src="https://i.stack.imgur.com/S2AuE.png" alt="Correct Scenario"></p> <p>So in the first image I enter a A and then another A which outputs array(1) { [0]=> float(4.5) } when using var_dump()</p> <p>And in the second image the var_dump() is array(2) { [0]=> float(4) <a href="https://i.stack.imgur.com/id7kF.png" rel="nofollow noreferrer">1</a>=> float(3.5) }</p> <p>It is skipping the first row in the first image... just in case A is supposed to equal 4.0 in REG and 4.5 in HONORS. It might be the array_combine()</p> <p>Here is my php code:</p> <pre><code>//$_POST['grades'] for the grades &lt;option&gt; and $_POST['types'] for the type (REG, HONORS) foreach(array_combine($_POST['grades'], $_POST['types']) as $code =&gt; $count) { if ($code == "A") { if ($count == "REGULAR") { $GradeArray[] = 4.0; } else if ($count == "HONORS") { $GradeArray[] = 4.5; } else if ($count == "COLLEGE") { $GradeArray[] = 5.0; } } else if ($code == "B") { if ($count == "REGULAR") { $GradeArray[] = 3.0; } else if ($count == "HONORS") { $GradeArray[] = 3.5; } else if ($count == "COLLEGE") { $GradeArray[] = 4.0; } } else if ($code == "C") { if ($count == "REGULAR") { $GradeArray[] = 2.0; } else if ($count == "HONORS") { $GradeArray[] = 2.5; } else if ($count == "COLLEGE") { $GradeArray[] = 3.0; } } else if ($code == "D") { if ($count == "REGULAR") { $GradeArray[] = 1.0; } else if ($count == "HONORS") { $GradeArray[] = 1.5; } else if ($count == "COLLEGE") { $GradeArray[] = 2.0; } } else if ($code == "F") { if ($count == "REGULAR") { $GradeArray[] = 0.0; } else if ($count == "HONORS") { $GradeArray[] = .5; } else if ($count == "COLLEGE") { $GradeArray[] = 1.0; } } } </code></pre> <p>It might be the whole foreach() statement that needs reworking... I am up to writing the logic again if anyone says so...</p> <p>I don't want to clog up the question with code so if you absolutely need the html just ask and I will add in an edit. </p> <p>EDIT: I am also thinking I need to rewrite the logic... I have never used array_combine() before... I just need to make sure the corresponds with the related </p> <p>Thanks for the help!</p>
