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>

I am creating a quiz builder using SQL, HTML and PHP, whereby the user can insert their question and four answer choices for that question (A, B, C or D).
In the same form they can then choose what choice will be the correct answer from a dropdown. This should then assign the 'is correct' boolean value of that certain answer row to 1 in the database.
[my database structure and what my form should look like is attached]
<?php
include ("nav.php");
include("connect.php");
$quiz_id = htmlentities($_GET["quizid"]);
$quiz = "SELECT * FROM `q_quiz` WHERE q_quiz.id ='$quiz_id'";
$quizresult= $conn->query($quiz);
if(!$quizresult){
echo $conn->error;
}
?>

as kiks73 mentioned, you can assign values to the option of the Select and POST the selected one to your database as correct answer ID.
<html>
<select class="uk-select" id="form-stacked-select" name="correctAnswer">
<option value='1'>A</option>
<option value='2'>B</option>
<option value='3'>C</option>
<option value='4'>D</option>
</select>
</html>
If you select A, the value "1" would be sent to your database as correct answer (as long as you correct the SQL part in your php.
EDIT:
I got your question a bit late, sorry.
you need to POST the select aswell in order to get the nessecary information about the correct answer. You could try something like that:
<?php
//just a counter
$i = 1;
//correct boolean 1 or 0
$bool = 0;
if (isset($_POST['submit'])) {
include("connect.php");
$newquest = $conn->real_escape_string($_POST['question']);
$insertquest = "INSERT INTO q_questions(quiz_id, question)
VALUES ('$quiz_id', '$newquest')";
$resultquest = $conn->query($insertquest);
$quest_id = $conn -> insert_id;
if (!$resultquest) {
echo $conn->error;
}
foreach ($_POST['ans'] as $ans) {
//get the value of the selected answer
$correctAnswer = $_POST['correctAnswer'];
//check if the selected one matches with our counter
if($i == $correctAnswer)
{
$bool = 1;
}
else
{
$bool = 0;
}
$answers = $conn->real_escape_string($ans);
$insertans = "INSERT INTO q_answers (question_id, answer, correct) VALUES ('$quest_id', '$answers', $bool)";
$resultans = $conn ->query($insertans);
if (!$resultans) {
echo $conn->error;
} else {
header("Location: managequiz.php?quizid=$quiz_id");
}
$i ++;
} //END OF FOREACH LOOP
}
?>
If you POST the whole form, you can use anything in it. i made an ugly loop, which checks each time you instert an answer to your SQL DB, if this one is selected.
I have been working on a form that allows entering a menu item for a cafe establishment, alongside its ingredients (arrays of data). Unfortunately, a problem came up as it only executes 1 query even though 2 or more ingredients were entered in the form (dynamic, jQuery).
Here is the PHP code:
<?php
include("session.php");
if (isset($_POST['submit'])) {
$productname = $_POST['product_name'];
$categoryID = $_POST['categoryID'];
$price = $_POST['srp'];
// ingredients
$ingredients = $_POST['ingredients'];
$qty = $_POST['qty'];
$measure = $_POST['measure'];
if (!empty($productname) && !empty($categoryID) && !empty($price) && !empty($ingredients) && !empty($qty) && !empty($measure)) {
for ($i=0; $i < count($ingredients); $i++) {
if ($ingredients[$i] != "" && $qty[$i] != "" && $measure[$i] != "") {
mysqli_query($db, "insert into individual_ingredients values ('', '$productname', '{$ingredients[$i]}', '{$qty[$i]}', '{$measure[$i]}')");
}
}
mysqli_query($db, "insert into end_products values ('', '$productname', '$price', '', '$categoryID')");
mysqli_query($db, "insert into audit_trail values ('', now(), '{$_SESSION['login_user']}', 'New end product added')");
header("location: end_products.php");
} else {
echo '<font color="red">'."Incomplete data entered".'</font>';
}
}
?>
And here is the HTML form and JQuery:

Is there a problem with the loop or with the HTML form that prevents the second to the last set of values from being inserted? Any help would be appreciated.
The variable $role_id1 is not being fetched in $role_id in $_POST['add sub menu'].
I want to store $role_id1 in $role_id and insert into database.Afer i click the submit button the role_id1 is fetching the parent menu but after i click add sub menu the role_id is storing 0 at backend.But i want it to store the vale of role_id1 which is being fetched after i click submit.Suggest any solution if possible.
<?php
$dbcon = new MySQLi("localhost","root","","menu");
if(isset($_POST['add_main_menu']))
{
$menu_name = $_POST['menu_name'];
$parent_id = 0;
$role_id = $_POST['role_id'];
$menu_link = $_POST['mn_link'];
$sql=$dbcon->query("INSERT INTO menu VALUES('','$menu_name','$parent_id','$role_id','$menu_link')");
}
if(isset($_POST['add_sub_menu']))
{
$parent_id = $_POST['parent'];
$name = $_POST['sub_menu_name'];
$role_id = $role_id1;
$menu_link = $_POST['sub_menu_link'];
$sql=$dbcon->query("INSERT INTO menu VALUES('','$name','$parent_id','$role_id','$menu_link')");

$role_id1 = $_POST['role_id'];
The lifetime of $role_id1 is where your scripts stops (last line) and output is sent to the browser (you see the form again).
So on the line in the top of your code:
$role_id = $role_id1;
$role_id1 doesn't exists anymore. If you view your error-log (or turn on display_errors), you would see a Notice: Undefined variable: role_id1 in ...
If you want to keep that value, put it in a hidden element so that it will be included in the POST-data the next time you submit that form:
echo '<input type="hidden" name="previous_role_id" value="' . htmlspecialchars($_POST['role_id']) . '">';
One sidenote (for completeness), although the element is hidden the value can be altered by the user.
So I've made a drop down menu (using PHP), and I'm not sure how to make it so that it can be taken as an input into a HTML form?
This is the PHP code:
<?php
$dropdownsql = "SELECT prodName FROM tblProduct";
$dropdownresult = #mysqli_query($connect, $dropdownsql);
echo "<select name='prodID'>";
while ($row = mysqli_fetch_array($dropdownresult, MYSQLI_ASSOC)) {
echo "<option value='" . $row['prodID'] . "'>" . $row['prodName'] . "</option>";
}
echo "</select>";
?>
And this is the HTML form code:
<form action="addOrder.php" method="post">
<p>
Order Date*:
<input type="text" name="orderDate" maxlength='70' required>
<p>
Order Location*:
<input type="text" name="orderLocation" maxlength='255' required>
<p>
Order Product*:
<p>
Order System*:
<input type="text" name="orderSystem" required>
<p>
<input type="submit" name="submit" value="Add Order">* Means that the field is required.
<input type="hidden" name="submitted" value="TRUE">
</form>
*Note that I want the input for Order Product
I have rewritten this to make it secure. Check if it works for you:

In update query replace your table name with small letter.
replace Project with project
