我正在開發一個搜索器,我做了一個函數,從數據庫獲取數據,將每個廣告保存在一個變量中,並將另一個函數中的分頁保存到另一個變量中,所以他們可以在數組中返回以便在稍後打印在html中。ajax請求php函數沒有收到變量
它的工作方式如下:您點擊購買或租用按鈕,然後進入搜索頁面(/ search?do?= buy/rent),則必須選擇房產類型,可選城市/搜索。 Ajax通過發佈(到search.php,同一文件)發送數據,隱藏第一個容器,並在頁面末尾顯示第二個容器,其中包含具有分頁屬性的列表。
這些是主要的變量,一個腳本來隱藏/顯示容器:
$mode = filter_input(INPUT_GET, 'do', FILTER_SANITIZE_STRING); // buy or rent
$prop_type = filter_input(INPUT_POST, 'prop_type', FILTER_SANITIZE_STRING); // res or com AJAX
$city = filter_input(INPUT_POST, 'city', FILTER_SANITIZE_NUMBER_INT); // AJAX
$zone = filter_input(INPUT_POST, 'zone', FILTER_SANITIZE_NUMBER_INT); // AJAX
$page_number = filter_input(INPUT_GET, 'page', FILTER_SANITIZE_NUMBER_INT);
if (isset($page_number) && $page_number >= 1) {
$cont1 = 'display: none;';
$cont2 = NULL;
// need a way to get the prop_type (the checked checkbox before changing the page) without using $_GET.
} else {
$cont1 = NULL;
$cont2 = 'display: none;';
}
這是函數:
function get_prop_data($prop_type, $city, $zone, $page_number, $table, $targetpage) {
if ($prop_type == 'res') {
$table2 = 'res_prop';
} else if ($prop_type == 'com') {
$table2 = 'com_prop';
}
if ($city != 0) {
$optional_cond = ' WHERE t2.city = ' . $city;
$optional_cond2 = NULL;
if ($zone != 0) {
$optional_cond2 = ' AND t2.zone = ' . $zone;
}
} else $optional_cond = $optional_cond2 = NULL;
$mysqli = new mysqli('127.0.0.1', 'db', '123456', 'name');
// pagination
if ($stmt = $mysqli->prepare('SELECT COUNT(id) FROM ' . $table)) {
$stmt->execute();
$stmt->bind_result($totalitems);
$stmt->fetch();
if (!isset($page)) {
$page = (int)$page_number <= 0 ? 1 : (int)$page_number;
}
$limit = 4;
if ($page > ceil($totalitems/$limit)) {
$page = ceil($totalitems/$limit);
}
$start = ($page - 1) * $limit;
$stmt->close();
if ($stmt = $mysqli->prepare(' SELECT t1.id, t2.*
FROM ' . $table . ' t1
INNER JOIN ' . $table2 . ' t2 ON t2.id = t1.id
' . $optional_cond . $optional_cond2 . '
LIMIT ?, ?')) {
$stmt->bind_param('ii', $start, $limit);
$stmt->execute();
$stmt->bind_result($id, $id, $type, $status, $bhk, $baths, $area1, $area2, $age, $description, $price, $city, $zone, $img1, $img2, $img3, $img4);
$test = "";
while ($row = $stmt->fetch()) {
if ($status === 0) {
$possesion = 'En construcción';
} else if ($status === 1 || $status === 2) {
$possesion = 'Inmediata';
} else $possesion = 'Desconocida';
if ($prop_type == 'res') {
$is_res = '<p><span class="bath">Bed</span>: <span class="two">' . $bhk . ' BHK</span></p>
<p><span class="bath1">Baths</span>: <span class="two">' . $baths . '</span></p>';
} else $is_res = NULL;
$test .= '<div class="box-col">
<div class="col-sm-6 left-side ">
<a href="/single?id=' . $id . '"> <img class="img-responsive" src="' . $img1 . '" alt=""></a>
</div>
<div class="col-sm-6 middle-side">
<h4>Disponibilidad: ' . $possesion . '</h4>
' . $is_res . '
<p><span class="bath2">Built-up Area</span>: <span class="two">' . $area1 . ' m²</span></p>
<p><span class="bath3">Plot Area</span>: <span class="two">' . $area2 . ' m²</span></p>
<p><span class="bath4">Age of property</span>: <span class="two">' . $age . ' Year(s)</span></p>
<p><span class="bath5">Price</span>: <span class="two">' . $price . ' €</span></p>
<div class="right-side">
<a href="/contact" class="hvr-sweep-to-right more">Contact Builder</a>
</div>
</div>
<div class="clearfix"> </div>
</div>
';
$pagination = functions::getPaginationString($page, $totalitems, $limit, $adjacents = 1, $targetpage, $pagestring = "&page=");
}
} //else echo "Statement failed: " . $mysqli->error . "<br>";
} //else echo "Statement failed: " . $mysqli->error . "<br>";
return array($test, $pagination);
}
這是主代碼:
if (empty($_GET)) {
echo 'under construction';
}
else if (isset($mode) && $mode == 'buy') {
$table = 'to_sell';
$targetpage = '/search?do=buy';;
if (isset($prop_type)) {
$data = get_prop_data($prop_type, $city, $zone, $page_number, $table, $targetpage);
$test = $data[0];
$pagination = $data[1];
}
}
else if (isset($mode) && $mode == 'rent') {
$table = 'to_rent';
$targetpage = '/search?do=rent';;
if (isset($prop_type)) {
$data = get_prop_data($prop_type, $city, $zone, $page_number, $table, $targetpage);
$test = $data[0];
$pagination = $data[1];
}
}
else {
echo 'invalid url';
}
這是通過後發送複選框值的AJAX腳本(它不能正常工作,我沒有收到未定義的錯誤$prop_type
(我不知道爲什麼???),但我得到它$table2
,在於它的if ($prop_type == '')
內):
$('.search, .pagination').click(function() { // search button and change page
if ($('#res_prop').is(':checked')) {
$prop_type = $('#res_prop').val();
}
else if ($('#com_prop').is(':checked')) {
$prop_type = $('#com_prop').val();
}
$.post('search.php', { // same file, maybe self
prop_type: $prop_type,
city: $('select[name=city]').val(), // optional
zone: $('select[name=zone]').val(), // option value="0" by default
success: function(){
$('.cont-1').hide();
$('.cont-2').show();
}
});
});
它完美,如果我手動設置$prop_type = 'res';
。有任何想法嗎?
的另一個問題是,分頁按鈕鏈接不起作用,它只是觸發AJAX腳本(他們需要發送的數據,以其他方式改變網頁時,腳本將重新啓動)。
我真的很感謝任何腳本的優化。謝謝。
看起來你的語法不在[jQuery網站](http://api.jquery.com/jquery.post/) –
這是否意味着我不能發送'pr op_type'爲'search.php'並沒有重裝再次執行整個PHP腳本?對不起,我從來沒有使用ajax,我完全失去了。 –
不,這並不意味着。我沒有看到你的答案,但從語法上看,成功調用不應該是數據對象的一部分。 –
