How to use the value of a textbox in query?

How to use the value of a textbox in query? - javascript

How can I use properly the value of my textbox (ORDER_ID) in my query? What happening right now is, its need to click a button first in ordermodal.php in order to get the value of it, it didn;t get the value when I click the View Order. The output should be like this, when I click the View Order its getting already the value of it. I hope you can help me with my problem, I stucked at this. Thanks!
This is my code for order.php . This is where I click the View Order.
<tr>
<td><?= $order['order_id'] ?></td>
<td><?= $order['user_id'] ?></td>
<td><?= $date ?></td>
<td><?= $time ?></td>
<td><?= $order['order_deliveryCharge'] ?></td>
<td><?= $order['order_totalAmount'] ?></td>
<td><?= $order['address'] ?></td>

It would be nice if you use jquery.

Give this a try
margin-top is set to -20px make it -10px. Try it
CSS
.validation-advice{
margin-top: -10px;
}
hope this helps...

How to Create a Shopping Cart using Session in PHP

I'm having trouble creating a shopping cart. How do I make the output so that when I click the add cart button on my products table, it will appear on the cart?
//Product List

while ($row = mysqli_fetch_array($exec)) {

$product_quantity = $row['quantity'];
$product_price = $row['sell_price'];
?>

Ordering Page Flow (GIF)

None of your input element have name attributes so (I think) when you submit the form, the URL query parameters (if the form has GET method) or the request body parameters (POST method) won't be available and you can't "catch" the act of someone submitting the order. If you add them and handle the form submission (say by ifing on a isset($_POST['order']) you can INSERT the order into the DB and render the cart from the DB table. Also look into http://php.net/manual/en/mysqli.prepare.php to avoid SQL injection.

Passing javascript variable to PHP using ajax but it gives error

I am trying to pass my JavaScript variable using Ajax into my PHP script but that doesn't work it given me error that it is undefined index. both codes are in different files but both of them are accessible on the main page.
Here's my script.php
<script>
function get_child_options(){
var parentID = jQuery('#parent').val();
jQuery.ajax({
url: '/**/**/**/child_categories.php',
type: 'POST',
data: {parentID : parentID},
success: function(data){
jQuery('#child').html(data);
},
error: function(){alert("Something Went Wrong with child options. ")},
});
}
jQuery('select[name="parent"]').change(get_child_options);
</script>
And this is my php file
<?php
require_once $_SERVER['DOCUMENT_ROOT'].'/ **/core/init.php'; //Including database path stored in init.php
$parentID = (int)$_POST['parentID'];
$childQuery = "SELECT * FROM categories WHERE parent = '$parentID' ORDER BY category";
ob_start();
?>
<option value="">Select <strong>Child</strong> Category</option>
<?php while ($child = mysqli_fetch_assoc($childQuery)): ?>
<option value="<?= $child['id']; ?>"><?= $child['category']; ?></option>
<?php endwhile; ?>
<?php
echo ob_get_clean();
?>
in script the #parent is a form id i am passing to javascript using jQuery.
because of variable is not accessible PHP is not running query.
This is my products.php the main where page where this is happening
<?php
require_once $_SERVER['DOCUMENT_ROOT'].'/Online Store/core/init.php'; //Including database path stored in init.php
include 'includes/head.php'; //Including header

Is there any other way to do it? What I am trying to do is when user selects parent category I want child category to arrange as per parent category.

Try this:
<script>
function get_child_options(){
var parentID = $(this).val();
jQuery.ajax({
url: '/**/**/**/child_categories.php',
type: 'POST',
data: {'parentID' : parentID},
success: function(data){
jQuery('#child').html(data);
},
error: function(){alert("Something Went Wrong with child options. ")},
});
}
jQuery('select[name="parent"]').change(get_child_options);
</script>
Getting the Value by $(this) and putting single quotes around parentID data: {'parentID' : parentID},

var options = {

type: "POST"
};
$('#form_modulesadd').submit(function() {
$(this).ajaxSubmit(options);
return false;
});
after submitting the page I am not getting any values in $_POST
this code is working fine in the server.
In local Environment it's giving problem
I am using wamp server. I have already tried with var_dump(),print_r() but not getting any result.
Any help would be appreciated.
Thanks in advance.

In your options, you should specify the data that you want to send.
var options = {
beforeSubmit: showRequest,
success: showResponse,
url: site_url + 'controllers/ajax_controller/modules-ajax-controller.php',
type: "POST",
data: {data1: "your_data", data2: "your_data"}
};
Then, try:
<?php echo $_POST["data1"]; ?>
It will show the data send, here: your_data

Use data option to send the data to the server.
var options = {
...
data: $('#form_modulesadd').serialize(),
...
};
$('#form_modulesadd').serialize() will send the data from the form.
EDIT
Try ajax:
$('#form_modulesadd').submit(function() {
$.ajax(options);
return false;
});

use <form name="form_modulesadd" id="form_modulesadd" method="POST" enctype="multipart/form-data" action="<?=site_url?>controllers/ajax_controller/modules-ajax-controller.php'" class="form-horizontal" >
