Hello,

 

I am a bit lost on this one, still new PHP....

 

I am trying to follow this tutorial here using the PHP/mysqli method:

https://css-tricks.com/dynamic-dropdowns/

 

 

I am having a real problem, everything is connected and seems to be passing data to the "get" request as I see it in the console but my database data has spaces and it looks like the GET method only takes the first word.

 

ie:

 

This

<script>  $("#products").change(function() {  $("#product_prices").load("getter.php?choice=" + $("#products").val());});</script>  

 

 

Results in this in the console:

Uncaught Error: Syntax error, unrecognized expression: Bases 30cm (320gr)ga.error @ jquery.min.js:2ga.tokenize @ jquery.min.js:2ga @ jquery.min.js:2n.fn.extend.find @ jquery.min.js:2(anonymous function) @ jquery.min.js:4n.Callbacks.j @ jquery.min.js:2n.Callbacks.k.fireWith @ jquery.min.js:2x @ jquery.min.js:4n.ajaxTransport.k.cors.a.crossDomain.send.b @ jquery.min.js:4jquery.min.js:4 XHR finished loading: GET "http://site.com/admin/crud/orders/getter.php?choice=Pizza".

 
 
But the data that should be pulled from the database is: 
Pizza Bases 30cm (230gr)  
 
 
(with bracket and spaces)
 
But the GET is only taking the first word "pizza"
 
Any idea why please?
 
Here is the full code:
 
Index.php
 
<?php 
ob_start();
session_start();
$admin_permission = $_SESSION['admin_permission'];
if(($admin_permission) == 1){
//Session admin ID equal 1
}else{
header('Location: http://' . $_SERVER['HTTP_HOST'] . '/index.php');
exit();
}
?>
<?php include($_SERVER["DOCUMENT_ROOT"] . "/admin/includes/admin-header.php"); ?>

<?php
  // 5. Close database connection
 if(isset($connection)){ mysqli_close($connection);}
 ob_flush();
?>
<?php include($_SERVER["DOCUMENT_ROOT"] . "/admin/includes/admin-footer.php"); ?>

And here is the Getter.php

<?php

    $choice = mysqli_real_escape_string($connection, $_GET['choice']);
	$query = "SELECT price1 FROM products WHERE name='$choice'";
	$result = mysqli_query($connection, $query);
		
	while ($row = mysqli_fetch_array($result)) {
   		echo "<option>" . $row['price1'] . "</option>";
	}
	
	
	
	
?>

I am also just found out that only the first dropdown menu is initiating the getter.php search and not the others....still trying to figure out why.

One thing is your Ternary operator.

//change this
$name = isset($_POST['name']) ? $_POST['name'] : "";

//to this
$name = (isset($_POST['name'])) ? $_POST['name'] : "";

I wasn't able to see where you were passing PHP var to Javascript, however you can try this, it would be cleaner then trying to assign JQuery selector value.

var name = <?php echo htmlspecialchars(json_encode($name), ENT_NOQUOTES); ?>;

Doesn't make a difference.
