错误ajax和PHP“;未定义的索引”;


Error ajax and PHP "Undefined index"

我是AJAX的新手,所以如果解决方案显而易见,我很抱歉。我必须在不刷新页面的情况下将日期发送到MySQL表,而我目前在这方面遇到了问题。

代码给出我遇到以下错误:

"注意:未定义的索引:张贴在inserisci.php第6行"

FORM

 <form id="form" class="form-horizontal shadow-z-1" action="includes/inserisci.php" method="post">
        <fieldset>
            <legend style="text-align: center; position: relative; top: 8px;">Inserisci un Post</legend>
            <hr>
            <div class="form-group">
                <label for="inputTitle" class="col-lg-2 control-label">Titolo</label>
                <div class="col-lg-10">
                    <input type="text" class="form-control" id="inputText" name="titolo" placeholder="Scrivi qui il Titolo">
                </div>
            </div>
            <div class="form-group">
                <label for="textArea" class="col-lg-2 control-label" name="testo">Messaggio</label>
                <div class="col-lg-10">
                    <textarea id="messaggio"></textarea>
                </div>

                      <button type="submit" class="btn btn-primary" onClick='send(); return false;' >Submit</button>
                    </div>
        </fieldset>
    </form>

INSERISCI.JS

  function send(){
var content = $.ajax({
        type: "POST",
        url: "index.php",
        data: {titolo:titolo & post:testo}           
  })
  .done(function() {
    alert( "success" );
  })                                                 
  .fail(function() {
    alert( "error" );
  })                                                
  .always(function() {
    alert( "complete" );
  });
}

INSERISCI.PHP

<?php
include('../core.php');
$titolo=$_REQUEST ['titolo'];
$post=$_REQUEST ['post'];
$sql = mysql_query("");
mysql_close();
?>

其他问题。我需要在不刷新页面的情况下重新加载此内容。

索引.PHP

<?php $sql = mysql_query("")  or die ("Nessun errore");
    if (mysql_num_rows($sql) > 0)
    {

        while ($row = mysql_fetch_assoc($sql))
        {
            echo '
            <article class="flipper white-panel">
        <a class="flipcard flip" style="
        position: absolute;
        right: 0px;
        top: -10px;
        z-index:1;
    "><i class="material-icons" style="font-size: 40px;">bookmark</i></a>
        <div class="articolo">
        <img src="http://i.imgur.com/sDLIAZD.png" alt="">
            <h4><a href="#">'.$row ['titolo'].'</a></h4>
            <p>'.Markdown($row ['contenuto']).'</p>
             <div class="pull-right">
                            <span class="label label-default">alice</span>
                            <span class="label label-primary">story</span>
                            <span class="label label-success">blog</span>
                            <span class="label label-info">personal</span>
                            <span class="label label-warning">Warning</span>
                            <span class="label label-danger">Danger</span>
                          </div>
                          <hr>
                          </div>
        <div class="commenti">
            <ul class="comment-list">
                        <li>
                            <div class="comment-img">
                            </div>
                            <div class="comment-text">
                            </div>
                        </li>
                    </ul>
                    <input type="text" class="form-control inputcomment" placeholder="Lascia un Commento.."/>
                  </div>
      </article>
         ';
        }

    }

谢谢大家。

注意:

  1. 请不要使用mysql_*函数。它们已被弃用
  2. 您的代码容易受到SQL注入攻击。请务必向他们致辞

这是一个语法错误。这不是一个有效的JavaScript对象。将data对象更改为:

data: {titolo:titolo, post:testo}

此外,在使用.done之前,您需要关闭$.ajax

  var content = $.ajax({
        type: "POST",
        url: "index.php",
        data: {titolo:titolo & post:testo}           // Should be closed here.
  })
  .done(function() {
    alert( "success" );
  })                                                 // Should not be closed. Remove ;
  .fail(function() {
    alert( "error" );
  })                                                 // Should not be closed. Remove ;
  .always(function() {
    alert( "complete" );
  });
  // });                                                Remove this!

如果没有结果,请更改这些行:

$titolo = $_POST['titolo'];
$post = $_POST['post'];

等等,你得到这两个的值了吗?

var titolo = $('input[name="titilo"]').val();
var testo = $('input[name="testo"]').val();

这是因为您在AJAX请求中传递的数据不是有效的javascript对象,并且您没有从表单中获取变量:

data: {titolo:titolo & post:testo}

你应该做一些类似的事情:

var titolo = $('form input[name="titolo"]').val();
var testo = $('form input[name="testo"]').val();
data: {
   titolo:titolo,
   post:testo
}

此外,顺便说一句,当访问数组元素时,在变量和括号之间放一个空格是不好的。我很惊讶这竟然有效。

$_REQUEST ['titolo']

应该是

$_REQUEST['titolo']

如果您想使用ajax表单提交,请使用更新表单定义

<form id="form" class="form-horizontal shadow-z-1" action="#" method="post">

使用以下更新的javascript

function send() {
    var content = $.ajax({
        type: "POST",
        url: "process.php",
        data: {
            titolo:  "Value for titolo",
            post: "Value for post"
        }
    }).done(function() {
        alert( "success" );
    }).fail(function() {
        alert( "error" );
    }).always(function() {
        alert( "complete" );
    });
}
