Body
<p>I am trying to create a php form which uses autoselect to select an item, and from that selection, it populates the price input field and from that, populate the subtotal and total fields.</p> <p>I have a table called "accessories" which has the following fields:</p> <p>accessories_id | accessories_name | accessories_price</p> <p>I can get the first autoselect to work but Im not sure where to go from there. Im ok with php but with Javascript I am an utter novice and don't know where to start.</p> <p><strong>html file</strong></p> <pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Autocomplete</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script> <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" /> <script type="text/javascript"> $(document).ready(function(){ $("#accessories_name").autocomplete({ source:'getautocomplete.php', minLength:1 }); }); $("#accessories_name").autocomplete({ source:'getautocomplete.php', minLength:1, change: function( event, ui ) {} }); $( "#accessories_name" ).on( "autocompletechange", function( event, ui ) { $("accessories_price").val(ui.item.value); //sets price with the value from selected accessory // [...] other fields logic } ); $( "#quantity" ).change(function() { var subtotal = $("#accessories_price").val() * $("#quantity").val(); //don't forget to verify if are numbers $("#subtotal").val(subtotal); }) </script> </head> <body> <form method="post" action=""> Name : <input type="text" size="40" id="accessories_name" name="accessories_name" /> Price: <input type="text" size="30" id="accessories_price" name="accessories_price" /> Quantity: <input type="text" size="30" id="quantity" name="quantity" /> Subtotal: <input type="text" size="30" id="subtotal" name="subtotal" /> <br /> Name : <input type="text" size="40" id="accessories_name" name="accessories_name" /> Price: <input type="text" size="30" id="accessories_price" name="accessories_price" /> Quantity: <input type="text" size="30" id="quantity" name="quantity" /> Subtotal: <input type="text" size="30" id="subtotal" name="subtotal" /> <br /> Total: <input type="text" size="40" id="accessories_total" name="accessories_total" /> </form> </body> </html> </code></pre> <p><strong>php file</strong></p> <pre><code><?php mysql_connect("localhost", "db_user", "password"); mysql_select_db("db"); $term=$_GET["term"]; $query=mysql_query("SELECT * FROM accessories WHERE accessories_description LIKE '%".$term."%' ORDER by accessories_description"); $json=array(); while($accessories=mysql_fetch_array($query)){ $json[]=array( 'value'=>$accessories["accessories_name"], 'label'=>$accessories["accessories_name"]." - ".$accessories["accessories_id"] ); } echo json_encode($json); ?> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
