显示/隐藏常用输入字段然后发布到php

标签: php jquery

我正在为用户开发一个表单,他希望表单字段根据下拉菜单进行更改。因此,如果他选择“图书馆”作为设施名称,他应该在其面积,容量,数量和互联网可用性状态之间进行选择。另一方面,如果他选择“展览区”,他应该在类型,面积,容量,数量和互联网状态之间进行选择。正如您所看到的,它们是一个常见的“重复”字段,导致在php中接收插入数据时出现问题。

这是我的代码:

不得不坐下来盯着这一点。我会将您的PHP与HTML分开。对于这个答案,让我们称它们为form.html和handler.php。

form.html会有这样的形式,如下:

<div id="content">
     <h3>Facility Information</h3>
    <form action="handler.php" method="POST" enctype="multipart/form-data" id="addFac-form" novalidate>
        <div class="formLayout">
            <div class="required">
                <label>Facility name</label>
                <select name="name" id="viewSelector">
                    <option value="none"></option>

所以我们稍微更改了表单,以便POST,我们指示它将数据发布到handler.php。所以现在我们需要设置该文件以捕获发布的数据,并将其添加到数据库中。

我注意到您的脚本没有Query但您已连接到数据库。这是一个问题。这是我可以建议的内容,您必须修复它以匹配您的环境/数据库。

<?php 
// Check if we got a submission and then connect to the database
if(isset($_POST['add'])){
    // Conditionally set the variable or a Default value
    $name = isset($_POST['name'])?$_POST['name']:"none";
    $type = isset($_POST['type'])?$_POST['type']:"none";
    $area = isset($_POST['area'])?$_POST['area']:"none";
    $capacity = isset($_POST['capacity'])?$_POST['capacity']:"none";
    $quantity = isset($_POST['quantity'])?$_POST['quantity']:0;
    $internet = isset($_POST['internet'])?$_POST['internet']:"none";
    $available = isset($_POST['available'])?$_POST['available']:"no";
    $comments = isset($_POST['comments'])?$_POST['comments']:"none";
} else {
    die("Form data not submitted.\r\n");
}
$dbhost="localhost";
$dbuser="root";
$con = mysqli_connect($dbhost, $dbuser, "", "dahbuildings");
if (!$con){
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
// create a prepared statement
if ($stmt = mysqli_prepare($link, "INSERT INTO tableName (name, type, area, capacity, internet, available, comments) VALUES (?, ?, ?, ?, ?, ?, ?)")) {
    // bind parameters for markers
    mysqli_stmt_bind_param($stmt, "sssisss", $name, $type, $area, $capacity, $internet, $available, $comments);
    // execute query
    mysqli_stmt_execute($stmt);
    echo mysqli_insert_id($con) . ": $name, $type, $area, $capacity, $quantity, $internet, $available, $comments";
    // close statement
    mysqli_stmt_close($stmt);
}
mysqli_close($con);
?>

您现在也可以通过AJAX将数据发布到此表单处理程序,处理结果,显示结果或允许用户添加另一个。

我只是通过将字段名称更改为唯一来解决此问题。然后,我转换设施名称的开关(唯一具有旧形式的唯一名称的字段)。在每种情况下,我都收到相应的输入字段并插入它们。正如我想象的那样,这并不是什么大问题。
