我想獲得下面的AJAX腳本來傳遞一個下拉ID到PHP運行查詢,但它並沒有出現該變量實際上被傳遞。當我對PHP文件進行硬編碼時,查詢運行正常,但是當我嘗試動態執行查詢時,查詢返回「undefined」或根本沒有任何結果。AJAX沒有將變量傳遞給PHP的MySQL查詢
AJAX代碼
function ajax_post(){
var request = new XMLHttpRequest();
var id = document.getElementById("editorginfo").value;
alert (id);
request.open("POST", "parse.php", true);
request.setRequestHeader("Content-Type", "x-www-form-urlencoded");
request.onreadystatechange = function() {
if(request.readyState == 4 && request.status == 200) {
var return_data = request.responseText;
alert (return_data);
document.getElementById("orgeditname").value = return_data;
document.getElementById("orgeditphone").value = return_data;
}
}
request.send("id="+id);
}
PHP解析代碼
<?php
include_once('../php_includes/db_connect.php');
$searchid = $_POST['id'];
//$searchid = 1;
$sql = 'SELECT * FROM orginfo WHERE id = $searchid';
$user_query = mysqli_query($db_connect, $sql) or die("Error: ".mysqli_error($db_connect));
while ($row = mysqli_fetch_array($user_query, MYSQLI_ASSOC)) {
$orgid = $row["id"];
$orgname = $row["orgname"];
$orgphone = $row["orgphone"];
echo $orgname, $orgphone;
}
?>
不能確定該信息所在的迷路。當我提醒編號時,它會捕獲正確的信息,所以我認爲問題出在我的發送部分,但我無法弄清楚我做錯了什麼。任何幫助,將不勝感激。
在此先感謝。
