php - 使用 Jquery/ajax 将数据发送到数据库

Question

我一直在尝试填写我的表格，但我总是被卡住。我让它在禁用 jquery 的情况下工作。但是如果我打开 Jquery，它不会发送任何东西。 (我的元素检查没有错误)

我已经使用它一段时间了，我尝试了不同的解决方案(一些来自 Stack overflow 上不同主题的解决方案)，但我一直在做同样的事情。它可能是服务器端的东西，但我一直在想，如果是这样的话，它根本不应该工作。有没有人可能有想法？

服务器端:osb.php

<?php
//set connection variables

//connect to mysql server
$mysqli = new mysqli($host, $username, $password, $db_name);



//check if any connection error was encountered
if(mysqli_connect_errno()) {
echo "Error: Could not connect to database.";
exit;
}

$action = isset($_POST['action']) ? $_POST['action'] : "";



if($action=='create'){ //the the user submitted the form

//include database connection
include 'mysqli.php';

//our insert query query
//$mysqli->real_escape_string() function helps us prevent attacks such as SQL injection
$query  = "insert into organisation 
            set
                name = '".$mysqli->real_escape_string($_POST['name'])."', 
                continent = '".$mysqli->real_escape_string($_POST['continent'])."',

试试这个

这是修改后的html

html

    <form action='osb.php' method='post' border='0' id="form1">
    <div id = "container">  <br>
        <label>Name:            </label>    <input type='text' id="name" name='name' /><br>  <br>
        <label>Continent:       </label>    <select id="continent" name="continent"> <option>Africa</option><option>America</option><option>Asia</option> <option>Australia</option><option>Europe</option></select><br><br>
        <label>Country:         </label>    <input type='text' id="country" name='country' /><br><br>
        <label>Website:         </label>    <input type='text' id="website" name='website' /><br><br>
        <label>E-mail:          </label>    <input type='text' id="email" name='email' /><br><br><br>
        <label>Organisation:    </label>    <input type='text' id="nameorg" name='nameorg' /><br><br>
        <label>Category:        </label>    <input type='text' id="category" name='category' /><br><br>
        <label>Price per week:  </label>    <input type='text' id="price" name='price' /><br><br>
        <label>Currency:        </label>    <select id ="currency"  name="currency" >  <option> EUR </option> <option> DOL </option> <option> GBP </option></select><br><br>
        <label>Description:     </label>    <textarea id="description" rows="5" cols="40"  placeholder="Describe what kind of volunteer is welcome" name='description'/></textarea><br><br>
        <label>Wanted:          </label>    <textarea id="wanted" rows="5" cols="40"  placeholder="Describe what kind of volunteer is welcome" name='wanted'/></textarea><br><br>
        <label>Expectation:     </label>    <textarea id="expectation" rows="5" cols="40"  placeholder="Describe what a volunteer can expect"  name='expectation'/></textarea><br><br>
        <label>Extra:           </label>    <textarea id="extra" rows="5" cols="40"  placeholder="Describe what a volunteer can expect"  name='extra'/></textarea><br><br>

        <input type='hidden' name='action' value='create' />
        <input type='button' value='Submit' id="submit" />
        <input type="reset" value="Reset" class="reset-org">

        <a href='index.php'>Back to index</a> 
</form>

使用.serialize()，它会自动获取所有的表单数据

代码

    $(function(){

    $('#submit').click(function(){
     $('#container').append('<img src = "img/ajax/ajax-loader.gif" alt="Currently loading" id = "loading" />');
    $.ajax({

            url: 'osb.php',
            type: 'POST',
            data: $('#form1').serialize(),
            success: function(result){
                 $('#response').remove();
                 $('#container').append('<p id = "response">' + result + '</p>');
                 $('#loading').fadeOut(500);

               }

         });         

    });
 });

然后在你的 php 页面中添加这个

osb.php

<?php
$data=$_POST['serialize'];
$name=$data['name'];  //access data like this

?>
