使用PHP中的表格，我试图返回取决于输入的SQL值的SQL值？

Question

My DB looks like this

paynumber fullname linemanager
12345 John Smith Jack Jones
12346 Joe Bloggs Andy Smith

I want it so if you enter 12345 into a textfield it will return John Smith in the same text field

I've tried so many mysql_queries I don't know which one to post!

I'm not looking for full code, as I'm not bad at that, but please point me in the right direction!

Cheers!

    <?php


    $mysql_host = "host"; 
    $mysql_username = "user"; 
    $mysql_password = "pass"; 
    $link = mysql_connect("$mysql_host", "$mysql_username", "$mysql_password");
    mysql_select_db("dbname",$link); 

    $pay_number=intval($_POST["pay_number"]);
    $result = mysql_query($link,"SELECT fullname from officers where paynumber=$pay_number");

    echo $result;

    ?>

Answer 1

SELECT fullname from myTable where paynumber=12345

What's so tough about it? Then you can display it anywhere you like. Can add a little bit of AJAX to grab the result and show in the same field.

EDIT:

Lets say your field on your HTML form was named pay_number and form method was POST

Then in your PHP processing code you could do

$pay_number=intval($_POST["pay_number"]);
$query="SELECT fullname from myTable where paynumber=$pay_number";
