在按鈕單擊php上顯示新的查詢結果
[英]Display new query results on button click php
問題描述
我有一個頁面在加載時顯示查詢結果。 還有一個日期范圍選擇器，選擇該日期范圍選擇器時必須運行相同的查詢並顯示更新的結果。 該頁面加載完美，但是當我選擇日期范圍並單擊按鈕時，什么也沒有發生。 這是頁面的代碼和圖像。 我是php和html的新手，通過構建Web應用程序進行學習。 因此，請問如果我的問題很基礎又愚蠢，請原諒。 頁面截圖

您需要<form>標記來發送數據。 喜歡
<form action="" method="">
<div class="row">
<div class="col-md-8">
<label class="control-label" for="fromdate">From:</label>
<input type="date" class="form-control" id="fromdate" name="fromdate">
<label class="control-label" for="todate">To:</label>
<input type="date" class="form-control" id="todate" name="todate">
<button type="submit" class="btn btn-success" name="todate" id="todate" style="width: 10%;" value="Date Run" >Go</button>
</div>
</div>
</form>

首先設置您的ID唯一。
<button type = "submit" class = "btn btn-success" name = "btnTodate" id = "btnTodate" style = "width: 10%;" value = "Date Run" >Go</button>
像這樣用過的Ajax
$(document).on('click', 'btnTodate', function(){
var dataValue = {setQuery: 1, data: $("#form_ID").serialize()}
$.ajax({
url: 'YOUR_PHP_FILE',
dataType: "json",
data: dataValue, success: function (r) {
}})});
您可以在此處顯示的表單中獲取所有設置的數據
YOUR_PHP_FILE.php
if (isset($_REQUEST['setQuery'])) {
$dataAuto = array();
parse_str($_POST['data'], $dataAuto);
if (!empty($dataAuto["todate"])) {
$main_query = mysqli_query($db, "SELECT count(a.pledge_id) total_pledges, sum(case when processed_status = 'Approved' then 1 else 0 end) approved, sum(case when processed_status = 'Cancelled' then 1 else 0 end) Cancelled, sum(case when processed_status in ('Alien','Single Gift') then 1 else 0 end) Gift, sum(case when processed_status is null then 1 else 0 end) Pending from waysact_source a left join vlc_processed_item b on a.pledge_id = b.pledge_id where a.fundraiser in (select distinct concat(f_firstname,' ',f_lastname) fundraiser from fundraiser where f_company in (select contractor_name from contractor where company_name = '{$_SESSION['login_user']}')) and a.pledge_date = '2017-06-06'");
$main_query_result = mysqli_fetch_row($main_query);
$main_total_pledges = $main_query_result[0];
} else {
$main_query = mysqli_query($db, "SELECT count(a.pledge_id) total_pledges, sum(case when processed_status = 'Approved' then 1 else 0 end) approved, sum(case when processed_status = 'Cancelled' then 1 else 0 end) Cancelled, sum(case when processed_status in ('Alien','Single Gift') then 1 else 0 end) Gift, sum(case when processed_status is null then 1 else 0 end) Pending from waysact_source a left join vlc_processed_item b on a.pledge_id = b.pledge_id where a.fundraiser in (select distinct concat(f_firstname,' ',f_lastname) fundraiser from fundraiser where f_company in (select contractor_name from contractor where company_name = '{$_SESSION['login_user']}'))");
$main_query_result = mysqli_fetch_row($main_query);
$main_total_pledges = $main_query_result[0];
}
die;}
