如何将PHP / Jquery / Ajax脚本修改为具有多个表单域

我不是php专家，但这应该可以帮助您：

首先更改主页上的表单区域：

<div >    <textarea name="content_txt" id="contentText" cols="45" rows="5"></textarea><br/>    <input type="text" id="balance" /><br/>    <input type="text" id="acctNum" /><br/>    <input type="text" id="monthly" /><br/>    <button id="FormSubmit">Add record</button></div>

那么您的myData看起来像这样：

var myData = {    content_txt: $("#contentText").val(),    balance: $("#balance").val(),    acctNum: $("#acctNum").val(),    monthly: $("#monthly").val()};

然后在ajax响应中：

$("#contentText").val(''); //empty text field after successful submission$("#balance").val('');$("#acctNum").val('');$("#monthly").val('');

最后是PHP：

//sanitize post value, PHP filter FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH$content = filter_var($_POST['content_txt'],FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);$balance = filter_var($_POST['balance'],FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);$account = filter_var($_POST['acctNum'],FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);$monthly = filter_var($_POST['monthly'],FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);$qry= "INSERT INTO add_delete_record(content,balance,account,monthly) VALUES('".$content."','".$balance."','".$account."','".$monthly."')";// Insert sanitize string in recordif(mysql_query("INSERT INTO add_delete_record(content,balance,account,monthly) VALUES('".$content."','".$balance."','".$account."','".$monthly."')")){    //Record is successfully inserted, respond to ajax request    $my_id = mysql_insert_id(); //Get ID of last inserted record from MySQL    echo '<li id="item_'.$my_id.'">';    echo '<div ><a href="#"  id="del-'.$my_id.'">';    echo '<img src="images/icon_del.gif" border="0" />';    echo '</a></div>';    echo $content.'</li>';    mysql_close($connecDB);}else{    //output error    //header('HTTP/1.1 500 '.mysql_error());    header('HTTP/1.1 500 Looks like mysql error, could not insert record!');    exit();}
