将Javascript数组返回到隐藏的输入值

我遇到了更改隐藏输入类型值的问题。我有一个搜索，它使用PHP while循环创建了多个复选框。我希望在提交后将签入PHP变量的项目传递给PHP。这是带有复选框和隐藏值的窗体

$search_sql = "SELECT * FROM `company` WHERE `groups` = '$groups' AND (`companyname` LIKE '%$search%' OR `directurl` LIKE '%$search%' OR `email` LIKE '%$search%' OR `phone` LIKE '%$search%' OR `groups` LIKE '%$search%' OR `notes` LIKE '%$search%')"; 
                $result = mysql_query($search_sql) or die(mysql_error());
                while($row = mysql_fetch_array($result))
                {   

                    //remove the http from the links
                    $website  = $row['directurl'];
                    $website = str_replace("http//", "", "$website");
                    $website = str_replace("http://", "", "$website");
                    $website = str_replace("https://", "", "$website");
                    $website = str_replace("https//", "", "$website");


                    //button to change colour

                    //display contacted companies
                    if($row['contact'] == 0){
                    //not contacted
                    $changecolor = '1';
                    $contacted = '<tr class="nocontact border">';
                    $button = '<td>

我可以得到一个确认框来显示正确的值，但我无法更改隐藏值的值，这将起作用。我想这可能是因为表单在while循环中，表单应该在循环之外。我们将非常感谢您对此事的任何帮助。

您正以相反的方式处理此问题，并且在前端暴露了太多不可篡改的信息。它还造成了大量不必要的冗余（冗余是程序员的死敌）。此任务不需要Javascript

您应该传递给浏览器的只是相关的公司信息，以填充单个表单；然后在提交后在PHP中构建适当的输出

搜索结果.php

echo "<form name=\"select_comp\" method=\"POST\" action=\"select_comp.php\">";

$search_sql = "
SELECT id FROM `company` WHERE `groups` = '$groups'
AND (`companyname` LIKE '%$search%'
OR `directurl` LIKE '%$search%'
OR `email` LIKE '%$search%'
OR `phone` LIKE '%$search%'
OR `groups` LIKE '%$search%'
OR `notes` LIKE '%$search%')"; 

$result = mysql_query($search_sql) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
    echo "<input type=\"checkbox\" name=\"id[{$row['id']}]\" value=\"1\"> {$row['company_name']}<br>";
    // echo other company details
}

echo '
<input type="submit" value="C">
</form>';

// $_POST['id'] will contain an array of selected checkboxes
// implode array into a comma-separated list for use with MySQL IN operator
// escaping a string where the numbers have been tampered with will cause an error, but it will be safe from injection
$sql = "
SELECT * FROM `company` WHERE `id`
IN (" . mysql_real_escape_string(implode(',', $_POST['id'])) . ")";
$res = mysql_query($sql);
while($row = mysql_fetch_array($res)) {
        switch ($row['id']) {
                // first company
                case '0':
                        // build styling here
                break;

                // second company
                case '1':
                        // build more styling here
                break;

                // and so on
        }

        // output HTML with styling information computed above
}

但是，您真正应该做的是使用输入到数据库和/或由文件命名约定确定的值动态设置样式（当然，这涉及动态生成的样式规范的绝对验证）。

感谢Voodoo417，我在上面添加了整个while循环，表单位于//按钮下，用于选择公司有几十个表单。是吗？是的，是的，其他的可以忽略他们只是改变背景颜色和更新数据库//选择公司的按钮是不使用javascript函数更改值的按钮。被要求显示整个while循环。感谢“我希望在提交后将签入PHP变量的项目传递给您”——为什么需要JavaScript？只需提交from，然后您就可以从服务器端获得值……没有javascript我该怎么做？我不需要检查项的值吗？Hanks recovering Nerdaholic对于您的答案，我现在用几个函数更改了我的脚本，这些函数的计算方式与我在这个问题中实现的不同。我同意我的脚本不是最佳实践，但它只是我自己使用的。感谢花费的时间和正确的方式完成这项任务，并帮助我了解未来的项目。再次感谢
