I have 3 forms with 3 radios each but executed one at a time because of random generator. If I click a radio, it will go to next page and will be checked by the if else statement. Now my problem is, when it gets answered and it's correct, it will output yes. However, my other if else statement of my other radio executes. Since it's not answered, it assumed that it was wrong, so it outputted no.
here's my code:
<!doctype html>

Here is a cleaner way to do it. Inside is_correct function, it check if particular answer exist in $_POST, if so it returns if the answer is correct:
function is_correct()
{
$answer = array(
'answerOne' => 'A',
'answer2' => 'B',
'answer3' => 'C',
);
foreach ($answer as $k => $v) {
if (array_key_exists($k, $_POST)) {
return $v == $_POST[$k];
}
}
return false;
}
if (is_correct()) {
echo "yes";
} else {
echo "no";
}

Its html page to ask question
Pre-function.php
<?php

function getQuestion($conn) {
$query = "SELECT * FROM question ";
$result = mysqli_query($conn, $query);
if($result){
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){
$question_id = $row['question_id'];
$question_body = $row['question_body'];
$option_a = $row['option_a'];
$option_b = $row['option_b'];
echo '
<h2 class="qtitle">'.$question_body.'</h2>
<label for='.$question_body.'>Yes</label>
<input type="radio" name="'.$question_id.'" value="Yes">
<input type="hidden" name="option_a" value="'.$option_a.'">

<input type="hidden" name="option_b" value="'.$option_b.'">
<input type="hidden" name="submitted" value="submitted"><hr>';
}
}
}
?>
Basically this form asked question whether yes or no using radio button. $option_a == 'Yes' and $option_b == 'No'. The question is like this "Are you have fever ?". So when i submit the value did not pass to the 'Answer.php' page.
'Answer.php' page.
<?php
include 'conn.php';
if(isset($_POST['Submit']) && !empty($_POST['Submit'])){
echo $_POST['option_a'];
echo 'succeed';
}
else{
echo 'no data';
}
?>
In this page have error undefined_index value but still echo succeed.
Your HTML code should look like the following:
<input type="radio" name="whatevername" value="Yes">
<input type="hidden" name="whatevername" value="No">
You can use PHP to insert whatever values you want but you need the radio button name to be the same.
Then if you want to echo that in PHP you'd use:
echo $_POST['whatevername']; //same name you used in the form
You are passing value as name for radio buttons
name="'.$option_a.'"
This will result you in name ="Yes"
And you are trying to fetch echo $_POST['option_a']; where option_a is not defined.
Try this
<input type="radio" name="'.$question_id.'" value="Yes">
<input type="hidden" name="option_a" value="'.$option_a.'">
Same for other radio button
Try this one :
<?php
include 'conn.php';
function getQuestion($conn) {
$query = "SELECT * FROM question ";
$result = mysqli_query($conn, $query);
if($result){
echo '<div class="A4">';
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){
$question_id = $row['question_id'];
$question_body = $row['question_body'];
$option_a = $row['option_a'];
$option_b = $row['option_b'];
echo '
<div class="A4">
<h2 class="qtitle">'.$question_body.'</h2>
<form action="Answer.php" method="post">
<label for='.$question_body.'>Yes</label>
<input type="radio" name="radioQuestions[]" value="'.$question_id.'-'.$option_a.'">
<label for="'.$question_body.'">No</label>
<input type="radio" name="radioQuestions[]" value="'.$question_id.'-'.$option_b.'">
<input type="hidden" name="submitted" value="submitted"><hr>';
}
echo'
<input type="submit" name="Submit" value="Submit">
</form>
</div>';
}
}
?>
<?php
include 'conn.php';
if(isset($_POST['submitted']) && !empty($_POST['submitted'])){
$questionAndOptions = $_POST['radioQuestions'];
foreach ($questionAndOptions as $questionAndOption) {
$arrQuestionAndOption = explode("-", $questionAndOption);
echo $arrQuestionAndOption[0]; //question
echo $arrQuestionAndOption[1]; //option
}
echo 'succeed';
}
else{
echo 'no data';
}
?>
<?php
if ($_POST['discount'] == 'text1')
echo "Discount Applied!";
else
header('Location:fifapack.html');
?>
I want to be able to add more words after text 1 and not just one valid word.
<div id="dicount">
<form action=discounts.php method=post>
<center>Discount Code:<input type=text name=discount>
<input type=submit value=Apply>
</center>
</div>
This is my html.
You can send several discounts this way:
<div id="dicount">
<form action=discounts.php method=post>
<center>Discount Code:<input type="text" name="discount[]">
<center>Discount Code:<input type="text" name="discount[]">
<center>Discount Code:<input type="text" name="discount[]">
<center>Discount Code:<input type="text" name="discount[]">
<input type=submit value=Apply>
</center>
</div>
And in your php:
$b = filter_input(INPUT_POST, 'discount', FILTER_SANITIZE_STRING, FILTER_REQUIRE_ARRAY);
if($b) {
// Do whatever you like with the array of discounts
}
To determine if text1 is in your POST, you can simply use:
if (strpos($_POST['discount'], 'text1')) {
...
}
If I understand you correctly you want to validate $_POST['discount'] against more
words?
<?php
if (($_POST['discount'] == 'text1') or ($_POST['discount'] == 'whatever')) {
echo "Discount Applied!";
}
else {
header('Location:fifapack.html');
}
?>
I want to write a php code that displays a random image and the person has to guess what it is. The problem is my php code tells me that the right city is incorrect, i cant figure out why
<?php
$random = rand(1, 3);
$answer ;
if ($random == 1) { $answer = "chicago" ;}
elseif($random == 2) {$answer = "LA" ;}
elseif($random == 3) {$answer = "NewYork" ;}
else {echo "Answer is None" ; }
if (isset($_POST["choice"])) {
$a = $_POST["choice"];
if($a ==$answer){
echo "<br> working <br>" ;
}else {echo "<br> Not Working <br>";}
}
?>
<!doctype html>

<head>
<meta charset="utf-8">

<body>
<center>
<img src="four/Image_<?php echo $random ;?>.jpg" width="960" height="639" alt=""/>
<form action="" method="POST">
chicago <input type= "radio" name="choice" value="chicago" />
<br>
LA <input type= "radio" name="choice" value="LA" />
<br>
NewYork <input type= "radio" name="choice" value="NewYork" />
<br>
<input type ="submit" value="Submit" />
</form>
</center>
</body>
</html>
You're generating your random value EVERYTIME the page is loaded. e.g. when the person first visits it and gets the form, you generate 2. When the form is submitted, you generate ANOTHER value, and this time it's 3. So even though the user correctly answers 2, you say they're wrong because the you've forgotten what you originally asked.
You need to store the generated value somehow, and compare that to the response, e.g.
$rand = rand(1,3);
<input type="hidden" name="correct_answer" value="$rand">
if ($_SERVER["REQUEST_METHOD"] == 'POST') {
if ($_POST['correct_answer'] == $_POST['user_answer']) {
echo 'correct';
}
}
The problem is your logic, you do not store the generated number that is used to show the image, instead you generate a new number every time you open the page.
You should store the generated number in (for example...) a session to preserve it and use that to compare.
Try it:
$random = floor(rand(1, 4));
I hope it helps.
Add the following hidden field in your form, using value="<?php echo $answer ?>" and it will work with your present code.
<input type="hidden" name="correct_answer" value="<?php echo $answer ?>">
Matter 'o fact, you don't even need name="correct_answer"
Just do:
<input type="hidden" value="<?php echo $answer ?>">
Remember when you test this, you have a "1 in 3" chance for success!
Edit
Here's the code that I used:
<?php
$random = rand(1, 3);
$answer;
if ($random == 1) { $answer = "chicago" ;}
elseif($random == 2) {$answer = "LA" ;}
elseif($random == 3) {$answer = "NewYork" ;}
else {echo "Answer is None" ; }
if (isset($_POST["choice"])) {
$a = $_POST["choice"];
if($a ==$answer){
echo "<br> working <br>" ;
}else {echo "<br> Not Working <br>";}
}
?>

I want to output the values of the checkbox in the same way I'm outputting the values from the text fields. Since the checkbox can have multiple inputs I'm using an array for that but trying to cycle through the array for values hasn't worked for me.
tried foreach($type as $item) and echoing $item within the HTML like it says in the PHP book I have but that hasn't worked.
How should I do and where should the code be? I'm also unable to use PHP within the HTML for some reason, I'm not sure why that is or if its something to do with the echo<<<_END or not. Help appreciated.
<?php // formtest.php
if (isset($_POST['game'])) $game = $_POST['game'];
else $game = "(Not entered)";
if (isset($_POST['genre'])) $genre = $_POST['genre'];
else $genre = "(Not entered)";
if (isset($_POST['type'])) $type = $_POST['type'];
else $type = "(Not entered)";
echo <<<_END

<title>Form Test</title>

<body>
Your game is: $game in the $genre genre and of the type<br />
<form method="post" action="formtest.php">
What is your game?
<input type="text" name="game" />
<br />
What is your genre?
<input type="text" name="genre" />
<br />
Type?
Retail <input type="checkbox" name="type[]" value="Retail" />
Downloadable <input type="checkbox" name="type[]" value="Downloadable" />
Free <input type="checkbox" name="type[]" value="Free" />
<br />
<input type="submit" />
</form>
</body>
</html>
_END;
?>
With the form as it is now, $_POST['type'] will be an array since it's using checkboxes (and named appropriately), not radios. Here I just implode it for display, but you can loop through it like any array. It should be worth noting that any time you're wondering what a form is giving you, you can var_dump($_POST) or var_dump($_GET) depending on where the data is coming from. It helps a lot with debugging.
Here's what I got, I switched from heredoc, but your heredoc should work fine if you add $type back in somewhere, I didn't notice it in the original code:
<?php // formtest.php
if (isset($_POST['game'])) $game = $_POST['game'];
else $game = "(Not entered)";
if (isset($_POST['genre'])) $genre = $_POST['genre']; //Edit: Fixed line, oops
else $genre = "(Not entered)";
if (isset($_POST['type'])) $type = implode(', ',$_POST['type']);
else $type = "(Not entered)";
//Normally I'd specify a charset, but for simplicity's sake I won't here.
$type = htmlspecialchars($type);
$game = htmlspecialchars($game);
$genre = htmlspecialchars($genre);
?>
<html>
<head>
<title>Form Test</title>
</head>
<body>
Your game is: <?php echo $game; ?> in
the <?php echo $genre; ?> genre and of the type <?php echo $type; ?><br />
<form method="post" action="">
What is your game?
<input type="text" name="game" />
<br />
What is your genre?
<input type="text" name="genre" />
<br />
Type?
Retail <input type="checkbox" name="type[]" value="Retail" />
Downloadable <input type="checkbox" name="type[]" value="Downloadable" />
Free <input type="checkbox" name="type[]" value="Free" />
<br />
<input type="submit" />
</form>
</body>
</html>
Addendum:
If you switched and used radios like
<input type="radio" name="type" value="Downloadable" />
$_POST['type'] would be a simple string since you can only select one of the set.
To the file you post it the type[] will be saved as an array. For example
$a=$_POST['type'];
Although I don't find any point in doing this to radio-buttons, because their purpose is to pass only 1 value(unless you want specifically to).
Ok, first you don't need to echo the entire html output. Second your questions says radio buttons, but the html shows checkboxes. A radio field will only produce one result so you don't need [] after then name. Checkboxes will return an array when named with a []. So if you are using checkboxes you will need to process the result as an array. If you change the field to radio it should work fine.
<?php // formtest.php
if (isset($_POST['game'])) {
$game = $_POST['game'];
}
