<?php
$server = "localhost";
$username = "root";
$pass = "";
$dbname = "stinkspolitics_pl";
$conn = mysqli_connect($server, $username, $pass, $dbname);
if (isset($_GET['detail_customer'])) {
$quest_id = $_GET['detail_customer'];
$get_quest = "SELECT * FROM questions WHERE quest_id = '$quest_id'";
$getting_quest = mysqli_query($conn, $get_quest);
while ($row = mysqli_fetch_assoc($getting_quest)) {
$quest_title = $row['quest_title'];
$category_id = $row['category_id'];
}
}
if (isset($_POST['submit'])) {
$quest_t = $_POST['quest_t'];
$update = "UPDATE questions SET quest_title = '$quest_t' WHERE quest_id = '$quest_id'";
$run_update = mysqli_query($conn, $update);

</div>

The condition if (isset($_POST['submit'])) { will never evaluate to true, since there is no input element in the form with name="submit" (the button with name='submit' does not send the attribute by default).
Either change the condition:
if (isset($_POST['quest_t'])) { ...
Or, include an input element with name='submit', for example:
<input name="submit" type="hidden" />
Also, make sure to move the $_POST check at the beginning of the file and ensure that no other code will be evaluated in the PHP file (e.g. the rest of the HTML code) if a POST request has been received.

Just return false after at the end of the method.
jQuery has its own way of ensuring "preventDefault()" and it is just returning false from the submit handler.
Full background on this here:
event.preventDefault() vs. return false

Issue has been solved. By changing path and then putting path of js file again.

How to return second register form on submition?

I have a page with two registration forms individual and business type and individual type form is set as default the other form is hidden, it works fine. but when I switch it to second form and click on submit button it submits second form but returns to first form after submition even on errors it return to first form.
I want it to stay on second form on errors and after submition.
Here is my php :
if (isset($_POST["btnRegister"])) {
echo "Done";
}elseif (isset($_POST["btnbusiness"])) {
echo "Done";
}
HTML and js codes in my page:
function swapConfig(x) {
var radioName = document.getElementsByName(x.name);
for(i = 0 ; i < radioName.length; i++){
document.getElementById(radioName[i].id.concat("Settings")).style.display="none";
}
document.getElementById(x.id.concat("Settings")).style.display="initial";
}
<div class="col-10 clmiddle">
<label for="production"><b>Individual</b></label>
<input type="radio" onchange="swapConfig(this)" name="urlOptions" id="production" checked="checked" />
<label for="development"><b> Business</b></label>
<input type="radio" onchange="swapConfig(this)" name="urlOptions" id="development" />
</div>
First Form :
<div id="productionSettings" class="col-12">
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
<div class="col-6">
<input type="text" class="form-control" name="fname" placeholder="Name..." required>
<button type="submit" name="btnRegister" class="btn btn-primary right">Send</button>
</div>
</form>
</div>
Second Form :
<div id="developmentSettings" style="display:none" class="col-12">
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
<div class="col-6">
<input type="text" class="form-control" name="fname" placeholder="Name..." required>
<button type="submit" name="btnbusiness" class="btn btn-primary right">Send</button>
</div>
</form>
</div>
EDIT: I changed JS to php, Here is the solution.
PHP codes (which get url):
$path = $_SERVER['REQUEST_URI'];
$Aurl = explode(",",$path);
for ($i=0; $i<count($Aurl);$i++){
$Burl = str_replace("?", "/", trim($Aurl[$i]));
}
$url = htmlspecialchars(basename($Burl));
$FormPostUrl = basename($path);
Html part :
Checkbox :
<div class="col-10 clmiddle" style="margin-top: 20px;">
<label for="production"><b>Individual</b></label>
<input type="checkbox" value="<?php echo htmlspecialchars("register.php"); ?>" name="checket"
onClick="if (this.checked) { window.location = this.value; }" <?php if($url === htmlspecialchars("register.php")){ echo 'checked="checked"';}?>>
<label for="development"><b>Business</b></label>
<input type="checkbox" value="<?php echo htmlspecialchars("register.php?business");?>"
name="checket"
onClick="if (this.checked) { window.location = this.value; }" <?php if($url === htmlspecialchars("business")){ echo 'checked="checked"';}?>>
</div>
First Form :
<?php if($url === htmlspecialchars("register.php")){?>
<div id="productionSettings" class="col-12">
<form action="<?php echo htmlspecialchars($FormPostUrl); ?>" method="post">
<div class="col-6">
<input type="text" class="form-control" name="fname" placeholder="Name..." required>
<button type="submit" name="btnRegister" class="btn btn-primary right">Send</button>
</div>
</form>
</div>
Second form:
<?php } elseif($url === htmlspecialchars("business")){ ?>
<div id="developmentSettings" class="col-12">
<form action="<?php echo htmlspecialchars($FormPostUrl); ?>" method="post">
<div class="col-6">
<input type="text" class="form-control" name="fname" placeholder="Name..." required>
<button type="submit" name="btnbusiness" class="btn btn-primary right">Send</button>
</div>
</form>
</div>
<?php } ?>

You can use PHP to control whether display:none is added to your divs or not. Use an if statement (or a ternary operator might be neater syntax in the context) to make the decision about what to echo. Since the default is to display the production settings form, we only need to check whether the other form has been submitted or not, in order to know whether to change that.
e.g. something like this (untested):
<input type="radio" onchange="swapConfig(this)" name="urlOptions" id="production" <?php echo (isset($_POST["btnRegister"]) ? "" : 'checked="checked"'); ?> />
and
<input type="radio" onchange="swapConfig(this)" name="urlOptions" id="development" <?php echo (isset($_POST["btnRegister"]) ? 'checked="checked"' : ""); ?> />
and
<div id="productionSettings" class="col-12" <?php echo (isset($_POST["btnbusiness"]) ? "style='display:none'" : ""); ?>>
and
<div id="developmentSettings" class="col-12" <?php echo (isset($_POST["btnbusiness"]) ? "" : "style='display:none'"); ?>>
P.S. Unless you've massively simplified these forms for the purpose of your example, they appear to be basically identical. It's questionable whether you actually need two separate forms at all. The only difference appears to be the choice between "individual" and "business" - that could be handled by a single form with a radio button to choose the type, which would then simplify how you handle the postback as well, and reduce the amount of duplicated code and HTML. Of course if you're actually capturing more distinct fields for these forms than you've shown, then these remarks don't really apply.

How to get dynamic buttons value when button is click in PHP?

I have created dynamic buttons in php. I need to get the value of that button when particular button is click. And when we click the button, all information is fetch in to the form.
Here is my code for buttonclick
<?php
function dash()
{
include 'config.php';
$sql = "SELECT roomno FROM roombook";
if($result = mysqli_query($db, $sql))
{
$str = '';
while($row = mysqli_fetch_array($result))
{
// generate array from comma delimited list
$rooms = explode(',', $row['roomno']);
//create the dynamic button and set the value
foreach ( $rooms as $k=>$v )
{
$str .= '<input type="button" onClick="showDiv()" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';
}
}
return $str;
}
else {
echo "ERROR: Could not able to execute $sql. " . mysqli_error($db);
}
mysqli_close($db);
}
?>

You can create your button like this
$str .= '<input type="button" onClick="showDiv()" data-atribute-id="valueyouwant" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';
Script should be like
$("button").click(function() {
alert(this.id); OR
alert($(this).attr('id')); OR
alert($(this).attr('data')); OR
var btnid = $(this).attr('data');//which give you current clicked btn id
});

You can use this:
// is going to select all elements that its name start with *btn_* (your dynamic buttons)
$('[name^="btn_"]').click(function() {
//get the value of the button that was clicked
var buttonValue = $(this).val();
// send data to the other file using the action attribute of the form
$('form').submit();
});
Hope that can help.

How to validate a form in a bootstrap modal using PHP?

As soon as the form is submitted, the form is not validated and the modal is closed because the page is refreshed. I want the modal to stay open on submitting the form. The php is given below:
<?php
$nameerror = $studentiderror = $emailerror = "";
$subject = "Thank you for voting!";
$body = "Dear $_POST["name"], Thank you for voting for this sustainable initiative. Your vote is appreciated! Lots of love from the Beefarm Committee of the Erasmus Sustainability Hub!";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if ($_POST["submit"]) {
if (empty(($_POST["name"])) {
$nameerror = "Please enter your name" }
if (empty($_POST["studentID"])) {
$studentiderror .= "Please enter your student ID";
} else {
$result = "Thank you for voting!";
mail($_POST["email"], $subject, $body);
}
};
}
Here is the HTML of the modal, the PHP is embedded in the HTML, where the error messages should be shown when the form is validated after submission:
<div class="container">
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button class="close" data-dismiss="modal">x</button>
<h4 class="modal-title">Vote!</h4>
</div>
<div class="modal-body">
<p>
Let us know what you think! <br/>
By voting, you as a student can have a say in the realisation of this project. Even if you vote
against having bees on campus, your vote is appreciated! <br/>
Thank you!
</p>
<form id="votingscreen" method="POST">
<?php echo $result ?>

</div>
</form>
</div>
</div>
</div>
</div>
</div>
This is the JS code:
$(".contentContainer").css("min-height", $(window).height());
$("#image").css("min-height", $("#beeweek").height());
$(document).ready(function () {
$("#submitButton").click(function () {
$("#myModal").modal('show');
})
});
$(".video-container").css("min-height", $(window).height());

If you don't want the page being refreshed, you should submit your form using Ajax, this link should help you, jQuery Ajax POST example with PHP

Ajax callback only applying to top div in list of jquery form groups

Hello smarter people,
So as the title conveys, i'm having some difficulties, and I've wasted a good 8 hours trying to figure it out :)
I posted a Question earlier, to which I got no answers. I was having difficulties with my ajax, and it's interaction with a form. This form is in an admin panel, and is for dynamically creating and editing navigation links on the front end of my (hopefully) soon-too-be site.
My problem specifically is: I am unable to, via ajax, have the text-content of the anchor tag (which causes the form to dropdown), to immediately reflect on screen...
http://i1379.photobucket.com/albums/ah126/conchairtoe/3_zpsb897a6a4.png
As you can see, the ajax has run, no errors, yet the label (anchor tag for enacting drop-down form) remains "test", when I typed "testing!!!!!!" in.
Everything behind the scenes worked, as the database successfully updates the corresponding data, and so does the anchor tag text once i reload the page, but that ain't very ajaxy now is it!
Here's the Javascript for when the form is submitted.
// NAV ITEM FORM - UPDATE / SUBMIT
$(".nav-form").submit(function(event) {
var navData = $(this).serializeArray(); // The serializeArray( ) method serializes all forms and form elements like the .serialize() method but returns a JSON data structure for you to work with.
var navLabel = $('input[name=label]').val();
var navID = $('input[name=id]').val();
$.ajax({
url: "ajax/navigation.php",
type: "POST",
data: navData
}).done(function(){
$("#label_"+navID).html(navLabel);
}); // END $.ajax
alert("navID = "+navID+" navLabel = "+navLabel);
event.preventDefault(); // will prevent form from submitting
});//END nav-form
Please note the .done callback.
I've narrowed the problem down!
The ajax works ONLY on whichever of the sortable anchors is in position 1 (the top of the list) - for when I change the "Home Page", or, again, which ever one I happen to move to the top of the list, the label updates immediately as per the ajax.
As you can see in the code, I have those alerts to verify this:
http://i1379.photobucket.com/albums/ah126/conchairtoe/final_zps7a7ddc68.png

So yea, I truly apologize for my ignorance. Bare in mind that I barely could grasp css just 2 months ago or so.
THANK YOU SO MUCH FOR YOUR HELP IF YOU CAN PROVIDE IT.

Because you are not looking at the current form for the navID. The code $('input[name=id]') is using the first element it finds. You need to look at the form, use find().
var form = $(this);
var navData = form.serializeArray();
var navLabel = form.find('input[name=label]').val();
var navID = form.find('input[name=id]').val();
