禁用的表单字段不提交数据[重复](4个答案)
两年前关门了。
我在尝试提交表单表时收到此错误(4次):
注意:未定义的索引:php/chartofcountsinclude.php中的accountid位于>第106行
我的代码是106行

$account_id = $_POST["accountid"][$i];

我正试图从本地数据库加载表数据。然后我允许用户访问某些字段来更改值。一旦他们完成,他们按下按钮提交,这是当我得到上述错误。数据库中目前有四个帐户,这意味着每次我的代码通过post值循环时,它都无法检索accountid。我已将相关代码粘贴到下面:
用户页chartofcounts.php

<?php
    include("view/SiteHeader.php");
    include('php/ChartOfAccountsInclude.php');
?>

<html>
    <head>
        <title>Chart of Accounts</title>
    </head>

    <body>
        <br/>
        <h2>Chart of Accounts</h2>
        <form action="" method="post">
            <div>
                <?php retrieveChart() ;?>
            </div>

            <div class="container">
                <button type="submit" name="submitMods" class="btn btn-outline-secondary">Submit Account Modifications</button>
            </div>
        </form>
        <?php if($submit_err) : ?>
            <?php generateError('warning', 'Account could not be updated.') ?>
        <?php endif; ?>
    </body>
</html>

php包括chartofcountsinclude.php

<?php
    include_once('php/session.php');
    $sql = "SELECT * FROM Accounts";
    $result = mysqli_query($db,$sql);
    $count = mysqli_num_rows($result);
    $submit_err = FALSE;
    $submitaccount_err = FALSE;

    function retrieveChart() {
        global $db;
        $funcSQL = "SELECT * FROM Accounts";
        $funcResult = mysqli_query($db,$funcSQL);

        echo '<table border="1" class="table table-bordered table-hover">

远离的 disabled 从输入字段
替换

echo '<td> <input name="accountid[]" disabled value="' . $row['account_id'] . '"> </td>';
echo '<td> <input name="accountname[]" value="' . $row['account_name'] . '"> </td>';
echo '<td> <input name="datecreated[]" disabled value="' . $row['date_created'] . '"> </td>';

echo '<td> <input name="accountid[]" value="' . $row['account_id'] . '"> </td>';
echo '<td> <input name="accountname[]" value="' . $row['account_name'] . '"> </td>';
echo '<td> <input name="datecreated[]" value="' . $row['date_created'] . '"> </td>';

如果你不允许人们编辑你可以使用的字段 readonly 代替 disabled .

在html中,具有禁用属性的元素不会被发布,或者您可以说它们的值不会被提交。
您的输入元素如下所示,因此它不会发布任何值。

<input name="accountid[]" value="' . $row['account_id'] . '" disabled />

禁用控件限制:
它不会被聚焦。
在选项卡导航中将跳过它。
无法成功过帐。
因此,如果您不想让用户编辑该输入,并且不需要向用户显示该输入,那么您可以尝试 input type="hidden" 具体如下:

<input type="hidden" name="accountid[]" value="' . $row['account_id'] . '" />

或者,如果您想向用户显示id,但不想让他们编辑,则可以在您的情况下使用readonly属性,通过readonly属性,您将能够发布字段的数据,例如,请参见下面的:

<input type="text" name="accountid[]" value="' . $row['account_id'] . '" readonly />

只读元素
可以接收焦点,但用户无法修改。
它将包含在选项卡导航中。
将成功发布。
不适用于复选框和选择标记

因为accountid是禁用字段,所以它不会提交,也不存在于$\u post变量中,所以您需要用隐藏字段替换您的文本框

线下更改

<input name="user_id[]" disabled value="' . $usernameRow['username'] . '">

<input name="user_id[]" type="hidden" value="' . $usernameRow['username'] . '">
