Use get url parameter in sql sent with ajax

I can successfully send post data with ajax and get data into mysql database. However I can't display when I use POST parameter in sql statement. İf I remove POST parameter from sql, data perfectly display where it should be.
What am I missing? Here what I've got.. thanks
**index.php**
<form method="POST" id="ask1">
<div class="form-group">
<input type="text" name="name" />
</div>
<div class="form-group" >
<textarea name="content" ></textarea>
</div>
<div class="form-group" >
<input type="hidden" name="service" value ="<?php echo ''.htmlentities($_GET["service"]).'' ?> ">
<input type="submit" name="submit" value="Submit" />
</div>
</form>
<div><span id="message" ></span></div>
<div id="display_message" ></div>
**ask.php**
$service = $_POST['service'];
$query = "SELECT * FROM ask WHERE comment_id = '0' and
service='".mysqli_real_escape_string($conn,$service)."' ";
$statement = $conn->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
$output = '';
foreach($result as $row)
{
$output .= '
<div class="panel-body" style="font-size:12px;">"'.$row["name"].'"</div>
';
$output .= get_reply_comment($conn, $row["id"]);
}
echo $output;
Ajax
<script>
load_comment();
function load_comment()
{
$.ajax({
url:"ask.php",
method:"POST",
success:function(data)
{
$('#display_message').html(data);
}
})
}
</script>

Show a div after the form is submitted (or after pressing the "Send" button)

My task is to make a div visible after submitting a form. The problem is: after submitting the form, the div appears for 0.5 sec, then it disappears again.
This is the relevant code part. I want to show the div with id="data".
<form action="" method="post" onsubmit="show_div()">
<div class="request">
<center>
<img id="logo" src="/img/n1_red.png" alt="">
<h1 id="t_request" class="item">Account Name</h1>
<br/>
<input type="text" id="request" name="Request" value="<?php echo $cloud; ?>" class="item"><br/>
<input type="submit" class="bttn" class="item" onclick="show_div()" value="Send" /><br/>
</center>
</div>
<div id="data" style="display:none">
<h2 id="t_mail">Mail</h2>
<p class="result"><?php echo $Email; ?></p>
<h2 id="t_password">Password</h2>
<input type="checkbox" id="pass_visibility" onclick="unhide_password()" value="Unhide pass"/>
<label for="pass_visibility" id="pass_visibility_label">(Unhide pass)</label>
<p class="pass_result" id="text_hidden_pass">Password is hidden.</p>
<p class="result" id="text_pass" style="display:none"><?php echo $Password; ?></p>
<h2 id="t_total_gb">Total GB</h2>
<p class="result"><?php echo $Total_GB; ?></p>
<h2 id="t_gb_used">Used GB</h2>
<p class="result"><?php echo $GB_Used; ?></p>
<h2 id="t_about">About</h2>
<p class="result"><?php echo $About; ?></p>
<h2 id="t_key">KEY</h2>
<p class="result"><?php echo $Decryption; ?></p>
<h2 id="t_authy">Authy</h2>
<p class="result"><?php echo $Authy; ?></p>
<h2 id="t_nr_acc">Acc name</h2>
<p class="result"><?php echo $Name; ?></p>
</div>
</form>
and this is the JavaScript code:
var div = document.getElementById("data");
function show_div() {
div.style.display = "block";
}
I tried to do this in 2 different methods:
First one was to add onclick="show_div() to the submit button.
<input type="submit" class="bttn" class="item" onclick="show_div()" value="Send" /><br/>
Then I added onsubmit="show_div()" to the submit form.
<form action="" method="post" onsubmit="show_div()">
As I said, with this method (after submitting the form/clicking the button) the result is not as expected. The div appears for 0.5 sec, then it disappears again.
Not sure if you need, but here is the CSS for id="data":
#data {
border-top: dashed 3px rebeccapurple;
border-left: dashed 3px rebeccapurple;
padding-left: 20px;
display: block;
}
And here the PHP code:
$cloud = "";
$Email = "";
$Password = "";
$Name = "";
$Total_GB = "";
$GB_Used = "";
$About = "";
$Decryption = "";
$Authy = "";
if($_SERVER["REQUEST_METHOD"] == "POST") {
$servername = "localhost";
$username = "root";
$password = "";
$db = "xxx";
$con = mysql_connect($servername,$username,$password);
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("xxx", $con);
$cloud = $_POST["Request"];
// Query
$query = "SELECT * FROM Clouds WHERE Name = '$cloud' LIMIT 1";
$result = mysql_query($query) or die(mysql_error());
if ($result >= 1) {
while($row = mysql_fetch_assoc($result)) {
$Email = $row['Email'];
$Password = $row['Password'];
$Name = $row['Name'];
$Total_GB = $row['Total_GB'];
$GB_Used = $row['GB_Used'];
$About = $row['About'];
$Decryption = $row['Decryption'];
$Authy = $row['Authy'];
}
} else {
//$error_not_found = "Account not found!";
}
}
I am missing something? Any advice for me? Thanks
Another Stack Overflow question:
I checked everything. I followed her tips too. No result. Well... The same result

This is a snippet you may use. It is not possible to show a div and send the form together, see the comment of esque above.
<form id="form1" action="..." method="post">
<!-- here your form fileds -->
</form>
// true = show div --- false = send form
var showDiv = true;
// form id selector
var myForm = document.querySelector("#form1");
// bind submit event to form
myForm.addEventListener("submit", function(event) {
if (showDiv == false) {
console.log('send form');
return;
}
event.preventDefault();
console.log('Show div, form not send');
var div = document.getElementById("data");
div.style.display = "block";
});

Form insertion into database not working asynchronously

I'm trying to get a text area's value inserted asynchrnously into my database, however it keeps redirecting to the PHP processing page, and echoing a result there. How would I get it to echo the result of the PHP script on the current HTML page?
JS:
$("#sub").click(function() {
$.post( $("#text").attr("action"), $("#text :input").serializeArray(),
function(info) { $("#result").html(info);});
});
$("#text").submit( function(){
return false;
})
PHP:
$sql = "UPDATE text
SET text_content = ? WHERE (id = 40) AND (number = $Number);";
$stmt = mysqli_stmt_init($connection);
if (!mysqli_stmt_prepare($stmt, $sql))
{
header("Location: ../create_text.php?error&prepare1111");
exit();
}
else
{
$stmt->bind_param("s", $content);
mysqli_stmt_execute($stmt);
mysqli_stmt_close($stmt);
$connection->close();
echo "successfully saved";
}
HTML:
<form type="text" method="post" onSubmit="return validateText(); toHTML();" action="processing.php" id="text">
<textarea name="content" rows="45" id="auto-expand" class="text-box" type="text"><?php echo stripslashes($content) ?></textarea>
<input type="hidden" name="id" id="id" value="<?php echo $id ?>">
<input type="hidden" name="number" id="number" value="<?php echo $number ?>">
<input type="hidden" name="updated" value="<?php echo $updated ?>">
<button type="submit" id="sub" name="submit">Save</button>
<button type="button" onClick="validateText(); toHTML();">Check</button>
<span id="result"></span>
</form>
Any help would be so great! :)

Try preventDefault:
$("#text").submit( function(e){
e.preventDefault();
})

Combining two or more submit buttons into one

I have submit buttons for different section of the webpage. The submit button is used to update the forms and database with the text value in the form fields. Currently, each submit button updates the forms (tied to their respective PKEY id, "consideration_no") only in their own sections. I want to update all the sections forms with one button click.
As you can see from the code below, there are 2 submit buttons. I have tried to link two together through IDs but it did not work for me.
// Include config file
require_once "config.php";
// Define variables and initialize with empty values
$question = $answer = "";
$question_err = $answer_err = "";

$consideration_no = $_REQUEST['consideration_no'];
$answer = $_POST['answer'];

if(empty($answer_err)){
// Validate address address
$input_answer = trim($_POST["answer"]);
if(empty($input_answer)){
$answer_err = "Please enter an answer.";

I want it to update all the fields, in different sections, with one submit button

your code was bit difficult to read, but from what i understood you are trying to combine two or more form submissions into one. It's quiet simple
<form method="POST" action="save.php">
<input type=text name=name[] />
<input type=text name=name[] />
</form>
by using the [] to identify the input element you can have multiple values with the same name where you can access them from the PHP script as an array.
For example the above example will produce an array as follows
<?php
print_r($_POST['name']); //("name" => Array....
is this clear enough for you? if not drop a comment, i will explain more. As a side note i do recommend you look into using template engine, and also a framework in your coding project.

Here's what I see when i separate the html into a new file. I tried to remove the excess forms but when I open the last collapsible section, it instantly executes a submit action and brings me back to the home page.
<button class="collapsible"><?php echo $section ?></button>
<div class="content">
<button class="collapsible"><?php echo $subsection ?></button>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<?php
//while loop start
?>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<div class="form-group <?php echo (!empty($answer_err)) ? 'has-error' : ''; ?>">
<label><?php echo $question; ?></label>
<input type="text" name="answer[]" class="form-control" value="<?php echo $answer; ?>">
<span class="help-block"><?php echo $answer_err;?></span>
<input type="hidden" name="consideration_no[]" value="<?php echo $consideration_no; ?>"/>
<input type="hidden" name="dg_no" value="<?php echo $dg_no; ?>"/>
</div>
<?php
//while loop ends
?>
<input type="Submit" name = "$consideration_no[]" class="btn btn-primary" value="Submit">
Cancel
</form>
</div>
<?php
//while loop start
?>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<div class="form-group <?php echo (!empty($answer_err)) ? 'has-error' : ''; ?>">
<label><?php echo $question; ?></label>
<input type="text" name="answer[]" class="form-control" value="<?php echo $answer; ?>">
<span class="help-block"><?php echo $answer_err;?></span>
<input type="hidden" name="consideration_no[]" value="<?php echo $consideration_no; ?>"/>
<input type="hidden" name="dg_no" value="<?php echo $dg_no; ?>"/>
</div>
<?php
//while loop ends
?>
<input type="Submit" name = "$consideration_no[]" class="btn btn-primary" value="Submit">

Any assistance would be greatly appreciated

You can use mysql_insert_id() to return the last ID generated my MySQL.
If you show your Database class I can give you an example.
