Question

im trying out something new for me that’s working with a MySQL database using PHP and Ajax to retrieve multiple data to a HTML page on loading.

HTML:

 <div id="name">Mark</div>
 <br/>
 <input id="realcost" value=""></input>
 <p id="size"></p>
 <div id="#desc">description</div>

Jquery:

function get() {
$.getJSON('data.php', {
    name: $("#name").text()
}, function(data) {
    $("input#realcost").val(data.cost);
    $("p#size").text(data.size);
    $("#desc").text(data.details);
    'json'
});
}
get();

what it dose is gets the text from name pass it to data.php and retrieves the values #realcost, #size and #desc

PHP:

 <?php
 mysql_connect( "localhost", "username", "password");
 $name = mysqul_real_escape_string ($_POST['name']);
 $cost = mysql_qery ("SELECT cost FROM list.itemlist WHERE name='$name'");
 $size = mysql_qery ("SELECT size FROM list.itemlist WHERE name='$name'");
 $details = mysql_qery ("SELECT details FROM list.itemlist WHERE name='$name'");
 echo json_encode(array("cost" => $cost, "size" => $size, "details" => $details));

 ?>

don’t know why i cant retrieve data into these feel’s.

Try this

<?php
 mysql_connect( "localhost", "username", "password");
 $name = mysql_real_escape_string ($_POST['name']);
$query = "SELECT cost, size, details FROM list.itemlist where name='$name'");
$row = mysql_fetch_assoc(mysql_query($query));

 echo json_encode(array("cost" => $row['cost'], "size" => $row['size'], "details" => $row['details']));

 ?>
