一些单选按钮不起作用，有些单独按钮

Question

我是PHP的新手，我收到错误。我在if statement内插入不同的单选按钮后，在条件被检查（在MySQLi查询上）后插入单选按钮。首先，当我插入8个单选按钮时当我插入20个单选按钮而不是前三个单选按钮不起作用时，其他工作正常！ 我很困惑导致这个错误的原因！

Answer 1

@hassan gul考虑@ chris85评论。您目前有OR条件：

Uncaught TypeError: Cannot read property 'Autocomplete' of undefined

这意味着如果poll_1或poll_1_image实际上有值，您将显示if语句中的内容

if(!empty($row2["poll_1"]) || !empty($row2["poll_1_image"]))

仅显示以上两者都有值（例如：您可以从数据库中返回）。

如果您的目标是让所有人都能够工作并进行显示，那么您需要在所有行中读取数据库中的数据

Answer 2

你搞砸了||和&& 在||的情况下，如果满足任何条件，则执行if-statement（true）。另一方面，只有在使用&&时两个条件都为真时才执行它。 试试这个：

if(!empty($row2["poll_1"]) && !empty($row2["poll_1_image"])){
    echo  "<div class='col-xs-12 col-md-4 col-sm-12 center'></br><img src='admin/uploads/".$row2["poll_1_image"]."'/>";
    echo $row2["poll_1"]."</p><input type='radio' name='poll[]' class='radio' value='male'/></div>";
}

修改 您在打开/关闭<p>标记时出错，请使用正确的语法。

Answer 3

我可能会建议制作与您的poll[]输入相关的具体数组键（例如，它们将是poll[poll_1]等。这可能会有所帮助，也可能没有帮助，这取决于您在做什么时做什么处理提交后的输入），然后使用for循环创建一个函数。如果你这样做或者不需要||或&&，我就无法破译，但看起来你需要&&：

<?php
    // Put this function declaration at the top of the page.
    // Better would be to put it on entirely different page and include the page at the top
    function makecheckbox($array = false, $key = false)
        {
            if(!empty($array[$key]) && !empty($array[$key."_image"])) { ?>
            <div class="col-xs-12 col-md-4 col-sm-12 center"><br />
                <img src="admin/uploads/<?php echo $array[$key."_image"]; ?>"/>
                <p><?php echo $array[$key]; ?></p>
                <input type="radio" name="poll[<?php echo $key; ?>]" class="radio" value="male"/>
            </div>
            <?php
                }
        }
?>

要在您的代码中使用

    while ($row2 = mysqli_fetch_assoc($slct_data)) {
        echo "<div class='col-xs-12 col-md-12 col-sm-12 text-center back'>".$row2['poll_title']."</div>";

        // Inside your while, use a for in place of all your "if" conditions
        for($i = 1; $i <= 20; $i++)
            makecheckbox($row2,'poll_'.$i);
    }

如果您创建了一个函数，几乎可以保证您的输出是相同的（您可能会复制并粘贴错误或更改一行而忘记更改其他等等。） 。它还可以清理页面并更容易发现语法错误。
