如何把每個 <select><option>將組合框轉換為PHP中的變量

[英]how to put every<select><option> combobox into a variable in PHP

問題描述

我的PHP腳本的輸出有點問題。

此頁面的目的是選擇票證狀態選項之一，例如：

  • 打開工單（顯示狀態為“新工單”或“正在審核”的數據庫工單）
  • 新票證（顯示狀態為“新票證”的數據庫中的票證）
  • 審核中（顯示狀態為“審核中”的數據庫票證）
  • 已關閉的票證（顯示狀態為已關閉的票證的數據庫中的票證）

用戶選擇狀態后，代碼必須顯示具有所選狀態的正確票證。

因此，我試圖做的是在每個選項之后放置一個數字變量，然后嘗試使其變為選中狀態，從而刷新頁面，並在頁面刷新時發送該選項的變量-除非它不起作用，大聲笑。

我一直在集思廣益，用不同的想法來檢查它從組合框中選擇狀態所獲得的變量，但是我還沒有弄清楚這是多么令人沮喪。

要點：

  • 該腳本必須在同一頁面上工作。 為每個不同的狀態創建一個新頁面是一項繁重的工作，而且效率不高。
  • PHP是主要的腳本語言，所以我更喜歡PHP中的答案

下面是當前代碼： 

<?PHP
session_start();
include('connection.php');

兩個想法：

a）您可以通過實現一些javascript來實現，這些javascript會在選擇更改后切換每個票證的顯示狀態。 

if ($_SESSION['staff'] >='6')
{

    echo "<select name='type' id='type' onchange='typeChanged()' onpropertychange='typeChanged()'>
    <option value='tab1'>Open Tickets</option>
    <option value='tab2'>New Tickets</option>
    <option value='tab3'>Under Review</option>
    <option value='tab4'>Closed Tickets</option>
    </select><BR>"; 
    echo "Current listed support tickets: <BR><BR>";

    echo "<div id="tab1" name="tabs">";
            $result1 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket' OR 'Under Review'");
            while ($row1 = mysql_fetch_array($result1))
            {
                $ticket1 = $row1['TicketID'];
                $user1 = $row1['name'];
                echo "Ticket ID: " . $row1['TicketID'] . "<BR>" . $row1['type'] . "<BR>Subject: " . $row1['subject'] . "<BR>Ticket Status: " . $row1['status'] . "<BR>";
                echo "<form action='detail_ticket.php?t=$ticket1' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";
                echo "<form action='reply_ticket.php?r=$user1' method='post' name='r_ticket' id='r_ticket'><input type='submit' name='reply_b' id='reply_b' value='Reply on Ticket!'></form>";
            }
    echo "</div>";

    echo "<div id="tab2" name="tabs">";
            $result2 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket'");
            while ($row2 = mysql_fetch_array($result2))
            {
                $ticket2 = $row2['TicketID'];
                $user2 = $row2['name'];
                echo "Ticket ID: " . $row2['TicketID'] . "<BR>" . $row2['type'] . "<BR>Subject: " . $row2['subject'] . "<BR>Ticket Status: " . $row2['status'] . "<BR>";
                echo "<form action='detail_ticket.php?t=$ticket2' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";
                echo "<form action='reply_ticket.php?r=$user2' method='post' name='r_ticket' id='r_ticket'><input type='submit' name='reply_b' id='reply_b' value='Reply on Ticket!'></form>";
            }
    echo "</div>";

    echo "<div id="tab3" name="tabs">";
            $result3 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket'");
            while ($row3 = mysql_fetch_array($result3))
            {
                $ticket3 = $row3['TicketID'];
                $user3 = $row3['name'];
                echo "Ticket ID: " . $row3['TicketID'] . "<BR>" . $row3['type'] . "<BR>Subject: " . $row3['subject'] . "<BR>Ticket Status: " . $row3['status'] . "<BR>";
                echo "<form action='detail_ticket.php?t=$ticket3' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";
                echo "<form action='reply_ticket.php?r=$user3' method='post' name='r_ticket' id='r_ticket'><input type='submit' name='reply_b' id='reply_b' value='Reply on Ticket!'></form>";
            }
    echo "</div>";

    echo "<div id="tab4" name="tabs">";
            $result4 = mysql_query("SELECT * FROM support WHERE status = 'Closed'");
            while ($row4 = mysql_fetch_array($result4))
            {
                $ticket4 = $row4['TicketID'];
                $user4 = $row4['name'];
                echo "Ticket ID: " . $row4['TicketID'] . "<BR>" . $row4['type'] . "<BR>Subject: " . $row4['subject'] . "<BR>Ticket Status: " . $row4['status'] . "<BR>";
                echo "<form action='detail_ticket.php?t=$ticket4' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";
                echo "<form action='reply_ticket.php?r=$user4' method='post' name='r_ticket' id='r_ticket'><input type='submit' name='reply_b' id='reply_b' value='Reply on Ticket!'></form>";
            }
    echo "</div>";


    echo "Click <A href='overview_page.php'>HERE</A> to return to the overview page.<BR>";
    echo "Click <A href='uitlogen_user.php'>HERE</A> to logout!<BR>";
}else
{
    echo "You need to be an GM or Admin to view this page!<BR>";
    echo "Click <A href='uitlogen_user.php'>HERE</A> to login!";
}

?>

<script type="text/javascript">
function typeChanged()
{
    var chosen = document.getElementById('type').value;
    var tabs = document.getElementsByName('tabs');
    for (var i in tabs)
    {
        tabs[i].style.display = 'none';
    }
    document.getElementById(chosen).style.display = 'block';
}
</script>

b）使用一些url參數重定向到該頁面，指示選擇了哪個票證，並顯示相應的票證。 

<?PHP
session_start();
include('connection.php');

if ($_SESSION['staff'] >='6')
{
    $chosen = isset($_GET['chosen']) ? $_GET['chosen'] : 'tab1';

    echo "<select name='type' id='type' onchange='typeChanged()' onpropertychange='typeChanged()'>
    <option value='tab1'>Open Tickets</option>
    <option value='tab2'>New Tickets</option>
    <option value='tab3'>Under Review</option>
    <option value='tab4'>Closed Tickets</option>
    </select><BR>"; 
    echo "Current listed support tickets: <BR><BR>";

    if ($chosen == 'tab1')
    {
            $result1 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket' OR 'Under Review'");
            while ($row1 = mysql_fetch_array($result1))
            {
                $ticket1 = $row1['TicketID'];
                $user1 = $row1['name'];
                echo "Ticket ID: " . $row1['TicketID'] . "<BR>" . $row1['type'] . "<BR>Subject: " . $row1['subject'] . "<BR>Ticket Status: " . $row1['status'] . "<BR>";
                echo "<form action='detail_ticket.php?t=$ticket1' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";

            }
    }

    if ($chosen == 'tab2')
    {
            $result2 = mysql_query("SELECT * FROM support WHERE status = 'New Ticket'");
            while ($row2 = mysql_fetch_array($result2))
            {
                $ticket2 = $row2['TicketID'];
                $user2 = $row2['name'];

這是AJAX如何為您工作的一個未測試（我沒有您的數據庫）示例。

如果您已經知道這一點，請原諒我，但是AJAX沒什么花哨的-它是一種簡單的方法，允許您從javascript調用另一個PHP文件。

AJAX的工作原理是擁有另一個PHP文件，該文件將完成下一部分工作，並將結果返回給javascript。 流程如下：

在File1中，javascript / jQuery抓住用戶選擇的選項，並“調用”（AJAX）第二個PHP文件，同時傳遞用戶的選擇。 實現這一目標的代碼在此位下： 

$('#type').change( function() { //grab the new value, send to File2 via AJAX });

File2（在此示例中命名為“ another_php_file.php”）（a）接收從File1發送的POSTed值，（b）執行數據庫查找，（c）構建新的HTML，以及（d）回顯所構造的代碼（在我稱為$ x的變量中）返回File1

現在，這非常重要：File1接收AJAX例程success:函數中的新代碼success:函數。 在此成功功能中，它可以使用jQuery更新File1中的div。 如果您希望用戶按下可用於執行其他AJAX查找的其他按鈕，則下一個AJAX查找也必須位於此成功函數之內。

無論如何，這應該可以回答您的直接問題：

文件1

                    alert('You chose: ' + chosen);

                    $.ajax({
                        type: "POST",
                        url: "another_php_file.php",
                        data: 'theOption=' + chosen,

                                alert('You clicked the button');

<?php

if ($_SESSION['staff'] >='6')
{
    //Note: the value text string MUST MATCH the value stored in the database, because it is this exact string you will search for in the 2nd php (AJAX) file.
    echo "<select name='type' id='type'>
        <option value='Open Ticket'>Open Tickets</option>
        <option value='New Ticket'>New Tickets</option>
        <option value='Under Review'>Under Review</option>
        <option value='Closed'>Closed Tickets</option>
    </select><br><br>
    <div id='report'></div>"; 

}else
{
    echo "You need to be an GM or Admin to view this page!<BR>";
    echo "Click <A href='uitlogen_user.php'>HERE</A> to login!";
}

?>

文件2-在此示例中必須稱為“ another_php_file.php”。 如果要更改名稱，還必須在上面的AJAX代碼段中更改文件的名稱： 

<?php
$chosen = $_POST['theOption'];
//die('You clicked: ' . $chosen);

    $result = mysql_query("SELECT * FROM support WHERE status = '$chosen' OR 'Under Review'");

        $x =  "Ticket ID: " . $row1['TicketID'] . "<BR>" . $row1['type'] . "<BR>Subject: " . $row1['subject'] . "<BR>Ticket Status: " . $row1['status'] . "<BR>";
        $x .= "<form action='detail_ticket.php?t=$ticket1' method='post' name='detail_t' id='detail_t'><input type='submit' name='detail_b' id='detail_b' value='View Ticket!'></form>";
        $x .= "<form action='reply_ticket.php?r=$user1' method='post' name='r_ticket' id='r_ticket'><input type='submit' name='reply_b' id='reply_b' value='Reply on Ticket!'></form>";
    }
}else{
    $result = mysql_query("SELECT * FROM support WHERE status = '$chosen'");
    while ($row1 = mysql_fetch_array($result1))
    {
        $ticket1 = $row1['TicketID'];
