目标:允许用户点击页面上的按钮/链接(称之为主页),会出现包含表单的模式。用户填写表单并单击“提交”按钮,将数据写入mysql。 Modal关闭,用户只看“主页”。
我有2/3工作。单击将创建使用表单加载的模式。添加到表单的数据将写入数据库。提交后模式关闭。 问题出在这个过程的最后。当用户提交时,模式关闭,用户将显示“表单”页面以代替“主机”页面。此外,表单似乎是将表单数据库两次插入数据库。
问题 我想做的是什么,如果是这样,我将如何改变这个过程?
代码(host.php)
主页
<div>
<h2>Test Section</h2>
<p> This <a id="target" href="http://localhost/dialogExperiments/TESTsingleformfeedback.php" title="Test Form">LINK</a> opens the feedback form.</p>
</div>
表格页面(form.php)
<body>
<!-- Begin forms section --><div>
<h1> Form</h1>
<!-- First section is php script to process this particular form-->
<?php
$browser = get_browser(null, true);//get array of viewing browser information. Used in POST below.
//Address error handling
ini_set ('display_errors', 1);
error_reporting (E_ALL & ~ E_NOTICE);
if (isset ($_POST['submit'])) {//Handle the form
if ($dbc = @mysql_connect ('localhost','root','root')) {
if (!@mysql_select_db ('feedback1')) {
die ('<p>Could not select the database because <b>' . mysql_error() . '</b></p>');
}
}else{
die('<p>Could not connect to MySQL because <b>' . mysql_error() . '</b></p>');
}
//Define the query. Note in this query we use the table "errors"
$query0 = "INSERT INTO errors (ID, words_omitted, jumbled_text, other, description, url, date_recorded, user, browser, operating_system)
VALUES (0, '{$_POST['words_omitted']}', '{$_POST['jumbled_text']}', '{$_POST['other']}', '{$_POST['description']}','{$_POST['url']}',NOW(),'{$_POST['user']}','{$_POST['browser']}','{$_POST['operating_system']}')";
//Execute the query
if (@mysql_query ($query0)) {
print '<p>The First form feedback has been recorded.</p>';
}else{
print "<p>Could not add entry because <b>" . mysql_error() . "</b> The query was $query0.</p>";
}
mysql_close();
}
?>
<!-- End process script and next display form-->
<!-- Begin Form 1 Errors--><div id="hideCategory1" class="formFrame">

Javascript / jQuery脚本是
$(document).ready(function() {
$('#target').each(function() {
var $link = $(this);
var $dialog = $('<div></div>')
.load($link.attr('href'))
.dialog({
autoOpen: false,
title: $link.attr('title'),
width: 600,
height: 500
});
$link.click(function() {
$dialog.dialog('open');
return false;
});
});
});
我很欣赏有关如何更改流程的任何指示,以便我可以使用模态表单。
感谢。

你有很多错误,包括你的流程
$('#target').each(function() {
不应该具有每个功能,因为ID应该始终是唯一的,因此不应该多于一个id =“target”。if(isset($_POST)){ /* mysql thingy goes here */ }
这就是为什么你发布了两次请请使用mysql_real_escape_string($ _ POST ['whatever']);
祝你好运,你应该修改更多:)
<强>已更新强>
if (isset ($_POST['submit']) && $_POST['submit']=='Add To Records') {
// check if the form was submitted
//do db thing here
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Not connected : ' . mysql_error());
}
// make foo the current db
$db_selected = mysql_select_db('foo', $link);
if (!$db_selected) {
die ('Can\'t use foo : ' . mysql_error());
}
//insert into db here using mysql_query();
//if there was no mysql_error(); then show the successfully message else error message
// please also check mysql_real_escape_string() on php.net its important so people don't hack ur
//db, n potentially the whole website itset.
//http://www.php.net/manual/en/function.mysql-real-escape-string.php
}else{
?>
<form>.....</form>
<?php
}
所以上面的代码,将检查表单,如果它已经先提交,然后连接,选择db name,然后插入db,其他明智的如果表单未提交则会显示表单。

请记住,您可以使用$(“#my_form_id”)。serialize()来获取$ .ajax调用的表单数据。
