My code now is in separate conditions. If I submit my form without insert any data, it must be two warning come out; if I insert no.of people, and submit it will show the required of age; if I insert the age and submit it will show the required of people.

But now when i submit my code without anything, it only show the warning of age? How to fix it by only php so that when i submit the form without anythings and two warning will pop out and call must be fill in this two fields

This code is process.php

<?php
$errors = [];
if (empty($_POST['people'])) {
    $errors[] = 'people';
}
if (empty($_POST['age'])) {
    $errors[] = 'age';
}

if (count($errors)) {
    header('Location: form.php?error=' . implode(",", $errors));
}

$person = $_POST['people'];
$ages = $_POST['age'];
$DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];
$date = date('H:i, jS F Y');

?>

<html>
    <head>
        <title>Result of Carbon Footprint Calculator </title>
</head>
<body>

<?php

echo "<p>Calculation processed at ".date('H:i, jS F Y')."</p>";
echo "<p>The calculation is as follow: </p>";

if ($person > 0) {
    echo $person." person in household<br/>";
}
if ($ages > 0) {
    echo $ages." age<br/>";
}

$outputstring = $date."\t".$person." \t".$ages." \t";

@ $fp = fopen("$DOCUMENT_ROOT/car/ttl.txt", 'ab');

flock($fp, LOCK_EX);

if (!$fp) {
  echo "<p><strong> Your order could not be processed at this time.
        Please try again later.</strong></p></body></html>";
  exit;
}

  // write the file
fwrite($fp, $outputstring, strlen($outputstring));
flock($fp, LOCK_UN);
fclose($fp);

echo "<p>Calculation complete.</p>";
?>
</body>
</html>

This code is form.php

<?php
$errors = isset($_REQUEST['errors']) ? $_REQUEST['errors'] : '';
if ($errors) {
    $arr = explode(",", $errors);
    foreach ($arr as $error) {
        if ($error == 'people') {
            echo "you need to enter name<br>";
        }
        if ($error == 'age') {
            echo "you need to enter age<br>";
        }
    }
}
?>

<html>
<head>
    <h1>Members</h1>
       <style>
        .error {color: #FF0000;}
        </style>
</head>
<body>
    <form method="post" action="process.php">
            <tr>
                <td >Number of Person</td>
                <td><input type="text" name="people" >
                    <span class="error"></span>
                </td>
            </tr>
            <tr>
                <td>Age</td>
                <td><input type="text" name="age" size="18" maxlength="18">
                <span class="error"></span>
            </td>
            </tr>
            <tr>
                    <th colspan="2" align="right"><input type="submit" name="submit" value="submit"></th>
                  </tr>
        </table>
</form>

The code for exp9.php is relevant but you can send all errors as json or as comma separated string. Using GET parameters for this purpose isn't the ideal thing though. Maybe $_SESSION would have been better.

Validation part:

$errors = [];
if (empty($_POST['people'])) {
    $errors[] = 'people';
}
if (empty($_POST['age'])) {
    $errors[] = 'age';
}

if (count($errors)) {
    header('Location: exp9.php?error=' . implode(",", $errors));
}

exp9.php:

$errors = isset($_REQUEST['errors']) ? $_REQUEST['errors'] : '';
if ($errors) {
    $arr = explode(",", $errors);
    foreach ($arr as $error) {
        if ($error == 'name') {
            echo "you need to enter name<br>";
        }
        if ($error == 'age') {
            echo "you need to enter age<br>";
        }
    }
}

Update: The entire form page with errors should look like this (needs refactoring)




<?php
$errors = isset($_REQUEST['errors']) ? $_REQUEST['errors'] : '';
$error_people = "";
$error_age = "";
if ($errors) {
    $arr = explode(",", $errors);
    foreach ($arr as $error) {
        if ($error == 'people') {
            $error_people = "you need to enter name";
        }
        if ($error == 'age') {
            $error_age = "you need to enter age";
        }
    }
}
?>

<html>
<head>
    <h1>Members</h1>
       <style>
        .error {color: #FF0000;}
        </style>
</head>
<body>
    <form method="post" action="process.php">
            <tr>
                <td >Number of Person</td>
                <td><input type="text" name="people" >
                    <span class="error"><?php echo $error_people; ?></span>
                </td>
            </tr>
            <tr>
                <td>Age</td>
                <td><input type="text" name="age" size="18" maxlength="18">
                <span class="error"><?php echo $error_age; ?></span>
            </td>
            </tr>
            <tr>
                    <th colspan="2" align="right"><input type="submit" name="submit" value="submit"></th>
                  </tr>
        </table>
</form>
