Below is the code for a simple form with input/output. For some reason, only question one seems to be working and questions two and three simply echo back "Something is wrong." I coded all three questions the exact same way throughout so I'm not really sure why question two and three aren't processing correctly. Any advice would be greatly appreciated.
Here is the HTML form:
<form action="processor.php" method="post">
<h4>Question # 1</h4>
<p>What grade are you in?</p>
<label class="checkbox"><input type="checkbox" name="grade" value="1"> Freshmen</label>
<label class="checkbox"><input type="checkbox" name="grade" value="2"> Sophomore</label>
<label class="checkbox"><input type="checkbox" name="grade" value="3"> Junior</label>
<label class="checkbox"><input type="checkbox" name="grade" value="4"> Senior</label>
<h4>Question # 2</h4>
<p>What is your current GPA?</p>
<select>
<option name="gpa" value="4">3.5 or above</option>
<option name="gpa" value="3">3.0-3.4</option>
<option name="gpa" value="2">2.5-2.9</option>
<option name="gpa" value="1">2.0-2.4</option>
<option>Lower</option>
</select>
<h4>Question # 3</h4>
<p>Where do you excel the most academically?</p>
<select multiple="multiple">
<option name="school" value ="1">Mathematics</option>
<option name="school" value ="2">Literature</option>
<option name="school" value ="3">History</option>
<option name="school" value ="4">Humanities</option>
<option name="school" value ="5">Science</option>
</select>
<div class="button">
<button class="btn btn-primary" input type="submit" name="submit" href="processor.php">Submit</button>
</div>
</form>
Here is the processor:
<?php
function Grades () {
$grade = $_POST['grade'];
if ($grade =="1") {
echo "You're a freshmen";
} elseif ($grade == "2") {
echo "You're a sophomore";
} elseif ($grade == "3") {
echo "You're a junior.";
} elseif ($grade == "4") {
echo "You're a senior.";
} else {
echo "Something is wrong.";
}
}
function Gpa () {
$gpa = $_POST['gpa'];
if ($gpa =="1") {
echo "You strongly need to up your GPA.";
} elseif ($gpa == "2") {
echo "You're an average student.";
} elseif ($gpa == "3") {
echo "You're an above average student.";
} elseif ($gpa == "4") {
echo "You're an excellent sudent.";
} else {
echo "Something is wrong.";
}
}
function School () {
$school = $_POST['school'];
if ($school =="1") {
echo "You're into Math";
} elseif ($school == "2") {
echo "You're into Lit";
} elseif ($school == "3") {
echo "You're into history.";
} elseif ($school == "4") {
echo "You're into humanities.";
} elseif ($school == "5") {
echo "You're into science.";
} else {
echo "Something is wrong.";
}
}
include('viewpage.php');
?>
And the view page:
<h4>Question # 1</h4>
<p><?php Grades($grade); ?></p>
<h4>Question # 2</h4>
<p><?php Gpa($gpa); ?></p>
<h4>Question # 3</h4>
<p><?php School($school); ?></p>

Answer 1

The problem is here
<select name="gpa">
<option value="4">3.5 or above</option>
To access $_POST['gpa'] <select> tag should have name property as gpa not <option> tag
For $_POST['School']
<select name="school" multiple="multiple">
<option value ="1">Mathematics</option>

Answer 2

also i think some think wrong in view page code. Grades,Gpa,School function are not have variable. but you call these function like this,
<?php Grades($grade); ?>
<?php Gpa($gpa); ?>
<?php Gpa($School); ?>
replace these code like below
<?php Grades(); ?>
<?php Gpa(); ?>
<?php Gpa(); ?>
and also you will get error if user not select options in question1 n question 2. you must add code to check that..
