我正在构建一个使用 jQuery/AJAX 将数据发送到 php 页面的网站,然后从那里将其插入数据库。出于某种原因,没有插入代码,我根本没有得到任何回应。
我的JavaScript:
function insert_data(){
var title = debate_title.value;
var subtitle = debate_sub.value;
var sides = debate_sides.value;
$(function() {
$.ajaxSetup({
error: function(jqXHR, exception) {
if (jqXHR.status === 0) {
window.location.replace('errors/noConnection.html');
} else if (jqXHR.status == 404) {
window.location.replace('errors/noConnection.html');
} else if (jqXHR.status == 500) {
window.location.replace('errors/noConnection.html');
} else if (exception === 'parsererror') {
window.location.replace('errors/noConnection.html');
} else if (exception === 'timeout') {
window.location.replace('errors/noConnection.html');
} else if (exception === 'abort') {
window.location.replace('errors/noConnection.html');
} else {
window.location.replace('errors/noConnection.html');
}
}
});
});
$.ajax({
type: "POST",
url: "post_debate.php",
data: { post_title: title, post_sub: subtitle, post_sides: sidesm, ajax: 1 },
dataType: "json",
timeout: 5000, // in milliseconds
success: function(data) {
if(data!==null){
window.location.replace('show_debate.php?id=' + data);
}else{
window.location.replace('errors/noConnection.html');
}
}
});
}
我的 PHP 代码(post_debate.php):
<?php
require('connect.php');
$title = $_POST['post_title'];
$subtitle = $_POST['post_sub'];
$sides = $_POST['post_sides'];
$ajax = $_POST['ajax'];
$date = new DateTime();
$timeStamp = $date->getTimeStamp();
if($ajax==1){
$query = mysql_query("INSERT INTO debates VALUES('','$title','$subtitle','$sides','0','0','$timeStamp')");
$get_data = mysql_query("SELECT id FROM debates WHERE title='$title', subtitle='$subtitle', sides='$sides', timestamp='$timeStamp'");
while($id=mysql_fetch_array($get_data)){
$final_id = $id['id'];
}
exit($final_id);
}else{
die("404 SERVER ERROR");
}
?>
谢谢!

我的新 PHP 代码:
<?php
header("content-type: application/json");
require('connect.php');
$title = $_POST['post_title'];
$subtitle = $_POST['post_sub'];
$sides = $_POST['post_sides'];
$ajax = $_POST['ajax'];
$date = new DateTime();
$timeStamp = $date->getTimeStamp();
if($ajax==1){
$query = mysql_query("INSERT INTO debates VALUES('','$title','$subtitle','$sides','0','0','$timeStamp')");
$get_data = mysql_query("SELECT id FROM debates WHERE title='$title', subtitle='$subtitle', sides='$sides', timestamp='$timeStamp'");
while($id=mysql_fetch_array($get_data)){
$final_id = $id['id'];
}
print (json_encode(array("Id"=>$final_id)));
}else{
die("404 SERVER ERROR");
}
?>
我的新 Javascript .ajax:
$.ajax({
type: "POST",
url: "post_debate.php",
data: { post_title: title, post_sub: subtitle, post_sides: sides, ajax: 1 },
dataType: "json",
timeout: 5000, // in milliseconds
success: function(data) {
if(data!==null){
window.location.replace('show_debate.php?id=' + data['Id']);
}else{
window.location.replace('errors/noConnection.html');
}
}
});
