It was working, but only on chrome and only on my PC, suddenly it stopped working completely, after I closed and reopened chrome. Now it wont store any data in my session.

}
?>
Thank You!
I've written this code... but this fails to display text... not sure what's wrong with the code. I'm new to PHP and trying to create a page that gets customer details and puts it in SQL.
<!DOCTYPE html>
<html>
<body>
<?php
$initial="";
?>
<form method="post"
action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
Intials: <select id="cmbInitial" name="initial" onchange="showUser(this.value)">
<option value="0">Select initial</option>
<option value="1">Mr.</option>
<option value="2">Mrs.</option>
<option value="3">Ms.</option>
<option value="4">M/s</option>
</select> <br>
<br>
<input type="submit" name="submit" value="Submit"></form>
<br>
<br>
<?php
echo "Customer Intial: $initial <br>";
?>
</body>
</html>
Try this:
$initial="";
if(isset($_POST['initial'])){
$initial=htmlentities($_POST['initial']);
}
You correctly sent the POST however you didn't put the value given with the POST into the $initial variable.
<!DOCTYPE html>
<html>
<body>
<?php
$initial = "";
?>
<form method="post"
action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
Intials: <select id="cmbInitial" name="initial" onchange="showUser(this.value)">
<option value="0">Select initial</option>
<option value="1">Mr.</option>
<option value="2">Mrs.</option>
<option value="3">Ms.</option>
<option value="4">M/s</option>
</select> <br>
<br>
<input type="submit" name="submit" value="Submit"></form>
<br>
<br>
<?php
$initial = filter_input(INPUT_POST, "initial");//GET the input in post method
if ($initial == 1) {
$initial_value = "Mr.";
} elseif ($initial == 2) {
$initial_value = "Mrs.";
} elseif ($initial == 3) {
$initial_value = "Ms.";
} elseif ($initial == 4) {
$initial_value = "M/s";
} else {
$initial_value = "Select initial";
}
echo "Customer Intial: $initial_value <br>";
?>
</body>
</html>
Try,
<form method="post" action=<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>>
Intials: <select id="cmbInitial" name="initial" onchange="showUser(this.value)">
<option value="0">Select initial</option>
<option value="1">Mr.</option>
<option value="2">Mrs.</option>
<option value="3">Ms.</option>
<option value="4">M/s</option>
</select> <br>
<br>
<input type="submit" name="submit" value="Submit">
</form>
<br>
<br>
<?php
if(isset($_POST['initial'])){
$initial=$_POST['initial'];
} else {
$initial = "empty";
}
echo "Customer Intial : ".$initial;
?>
</body>
</html>
I am trying to display the saved data in the database on select before a user can update other choice. I am not really sure how to code it. Can anyone come out with possible solution? Had tried many ways but unable to do so.
Update: I have found out the problem why the options does not show.
This is my code:
`
$consentId = $_GET['consent_id'];
$retrieveConsent = "SELECT * FROM consent, leavetype WHERE consent.type_of_leave = leavetype.type_of_leave";
$retrieveResult = mysqli_query($link, $retrieveConsent) or die("Retrieve Error" . mysqli_error($link));
$queryleavetype = "SELECT * FROM leavetype";
$queryleaveresult = mysqli_query($link, $queryleavetype) or die("Leave Retrieve Error " . mysqli_error($link));
$row = mysqli_fetch_array($retrieveResult);
mysqli_close($link);
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Edit Consent </title>
</head>
<body>
<div class="ui-content">
<h3><b>Edit Leave</b></h3>
<form action="doEditConsent.php" method="post" data-ajax="false">
<input type="hidden" name="cId" value="<?php echo $row['consent_id']; ?>"/>
<label for="dateFrom" ><b>Date From:</b></label>
<input type="date" id="dateFrom" name="newDateFrom" value="<?php echo $row['consent_date_from']; ?>" required>
<br>
<label for="dateTo" ><b>Date To:</b></label>
<input type="date" id="dateTo" name="newDateTo" value="<?php echo $row['consent_date_to']; ?>" required>
<br>
<label for="reason" ><b>Leave Type:</b></label>
<select name="leaveType" id="leaveType" data-mini="true">
<?php
while ($rowleave = mysqli_fetch_array($queryleaveresult)) {
?>
<option value="<?php echo $rowleave['type_of_leave']; ?>">
<?php echo $rowleave['leave_type']; ?>
</option>
<?php
};
?>
</select>
<br>
<button class="ui-btn ui-corner-all" type="submit" >Submit</button>
</form>
</div>
<?php
}
}
?>
</body>
</html>`
Try this, hopefully it will help you:
<select name="leaveType" id="leaveType" data-mini="true">
<option value=""></option>
<?php
$previous_selected_value = 'previous_selected_value';//get the previous value and assign it to this variable
while ($rowleave = mysqli_fetch_array($queryleaveresult)) {
$selected = ($rowleave['type_of_leave'] == $previous_selected_value) ? " selected='selected'" : "";
echo '<option value="'.$rowleave['type_of_leave'].'"'.$selected.'>'.$rowleave['leave_type'].'</option>';
}
?>
</select>
So this has been bugging me for sometime, I want to pass a calculation which I have stored in a function onto another page, I can pass field entries no problem (sorry im newish at PHP) but how do i pass my calculation from:
// calculation section (calculator.php) - this is a include on every page
The calculation is made by a users entries which is in a include on every page
// The thank-you.php page outputs a thank you comment and sends the email
I receive all the other info fine but the function won't come through in my email.
The output from the calculation is also stored in calculator.php which is the include but it outputs to the screen fine just not to my email :(.
Am I missing something?
Sorry (edit) here is my code:

If you are using sessions, you can store the variable, results, array -- whatever into a session variable and then retrieve it on a new page.
session_start();
$_SESSION['test_var'] = 'Jake';
Then when I navigate to a new page and retrieve the var:
session_start();
echo $_SESSION['test_var']
// outputs 'Jake'
