If I got you right, you need to be able to search one of the three table as per user's selection using a phone number. I am not sure if you want to use Javascript, hope this can be helpful
First you need to pass both the Select and textbox values to searchtitle.php
function get_User() {
var user_data = {};
user_data['Book'] = document.getElementById("DropDownID").value; // get dropdown selected value
user_data['phone'] = document.getElementById("inputkeywor").value; // get dropdown selected value
$.ajax({
type: "POST",
url: "searchtitle.php",
beforeSend: function () {
$( "#LoadingDiv" ).html("Searching User...");
},
data: user_data,
success: function (data) {
Here Data is the result of searchTtitle.php.....
}}});
Then on searchtitle.php you get the values from
$keyword = $_POST['phone'];
$TableToQuery = $_POST['Book'];
call get_User on submit
<input type="button" class="keyword" value="search" onclick="get_User()" />
