Как изменить SQL поисковый запрос на основе значений переменных, полученных из формы фильтра HTML?

У меня есть блок формы, в котором раскрываются параметры поиска, пользователь выбирает хотя бы одну опцию выбора и нажимает кнопку Search, которая отправляет форму для отправки в сценарий JS, который получает значения всех или некоторых из выбранных значений и в зависимости от параметров выбора, запрос SQL изменяется.

Но проблема в том, что мне нужно сделать комбинацию выбора и изменить вручную sql запрос для выполнения и получения результата. Но я хочу сделать кое-что, в чем запрос SQL будет автоматически изменен на основе полученных параметров.

Руководство по PLZ.

Вот как выглядит мой фильтр.

Ниже код JS Скрипт loadtable.js

$(document).ready(function(){

    var delay = 1000;

    // Campaign Submit Info
    $('[name="search_submit"]').click(function(e){              

              e.preventDefault();

              var lead_status = $('#filterformpost').find('#lead_status_select option:selected').val();
              var campaign_status = $('#filterformpost').find('#campaign_status_select option:selected').val();
              var company_name = $('#filterformpost').find('#company_name_select option:selected').val();
              var tech_area = $('#filterformpost').find('#tech_area_select option:selected').val();
              var firm_size = $('#filterformpost').find('#firm_size_select option:selected').val();
              var firm_type = $('#filterformpost').find('#firm_type_select option:selected').val();
              var country_name = $('#filterformpost').find('#country_name_select option:selected').val();
              var state_name = $('#filterformpost').find('#state_name_select option:selected').val();
              var start_date = $('#filterformpost').find('#start_date_search').val();
              var end_date = $('#filterformpost').find('#end_date_search').val();

             $.ajax({
                           type: "POST",

                           url: "http://localhost/CRM/server/search.php",                        
                           data: {
                                    "lead_status":lead_status, 
                                    "campaign_status":campaign_status,
                                    "company_name":company_name,
                                    "tech_area":tech_area,
                                    "firm_size":firm_size,
                                    "firm_type":firm_type,
                                    "country_name":country_name,
                                    "state_name":state_name,
                                    "start_date":start_date,
                                    "end_date":end_date                          
                                  },
                           beforeSend: function() {
                             $('.message_box').html(
                             '<img src="tenor.gif" width="40" height="40"/>'
                             );
                           }, 
                           success: function(data)
                           {
                           setTimeout(function() {
                           $('.message_box').html(data);
                           }, delay);
                           }                   

                         });








});

И PHP файл, в котором, я думаю, будет поисковый запрос search.php

<?php 

//SQL Search query


include('connection.php');

if ( ($_POST['lead_status']!="") ){


    $lead_status = $_POST['lead_status'];
    $campaign_status = $_POST['campaign_status'];


    $selectSQL = "SELECT * FROM `tbl_main_lead_info`";

    $result = $conn -> query ($selectSQL);

    while ($row = mysqli_fetch_array($result)) {   

      //here i get the select condition which i need to display over the html page using AJAX


}




}

?>

Решение, которое я пытаюсь, как показано ниже:

Вам может потребоваться проверить, передается ли какое-либо значение для каждой переменной, и динамически построить запрос: 

<?php
include('connection.php');

$sqlFlag = 0;
function queryDelimiter(){
    global $sqlFlag;
    if ($sqlFlag == 0){
        $sqlFlag = 1;
        return ' WHERE ';
    }else{
        return ' AND ';
    }
}

$selectSQL = "SELECT * FROM tbl_main_lead_info";

if(isset($_POST['campaign_name']) and strlen(trim($_POST['campaign_name'])) > 0){
    $selectSQL .= queryDelimiter()."campaign_name = '".$_POST['campaign_name']."'";
}

if(isset($_POST['lead_status']) and strlen(trim($_POST['lead_status'])) > 0){
    $selectSQL .= queryDelimiter()."lead_status = '".$_POST['lead_status']."'";
}

$selectSQL .= " ORDER BY campaign_name";
