是否可以将下拉列表插入表格单元格

谢谢大家!

下面是一些代码:

$sql_query="SELECT nameOfwarning FROM warnings";
$sodss=mysqli_query($d,$sql_query);
if (mysqli_num_rows($result)<1)

?>
<select name = "warnings">
        <option value="Choose one of the warnings: " </option>
        <?php
            while ($row = mysqli_fetch_array($warnings)) {
                print "<option value=";
                print $row["id_warning"];
                print ">" ;
                print $row["warning"];
                print "</option>";
            }
        ?>
        </select><br>
<?php

print "<tr><td>Insert drop down list here?: </td><td><input type=\"text\" name=\"OR HERE\"></td></tr>";
$sql\u query=“选择来自警告的警告名称”;
$sodss=mysqli\u查询($d,$sql\u查询);
if(mysqli_num_行($result)


我还冒昧地格式化了您的代码。希望您不介意。您应该这样做作为一种常规做法,以使其更具可读性

<?php
$sql_query = "SELECT id_warning, warning FROM warnings";
$result = mysqli_query($d, $sql_query);

$dropDownHtml = '';
if (mysqli_num_rows($result) > 0) {

    $dropDownHtml .= '<select name = "warnings">'; 
    $dropDownHtml .= '<option value="Choose one of the warnings: " </option>';
    while ($row = mysqli_fetch_array($result)) {
        $dropDownHtml .= 
            '<option value="{$row["id_warning"]}">' . 
            $row["warning"] . 
            '</option>';
    }
    $dropDownHtml .= '</select><br>';
}
?>

<tr>
    <td><?php echo $dropDownHtml; ?></td>
    <td><input type=\"text\" name=\"OR HERE\"></td>
</tr>

看起来您跳过了一些代码,因为SQL查询应该返回的内容与结果数组不匹配,而且还有一些变量不匹配。我对其进行了一些更改,以使其看起来可信,如果您不想发布问题中的所有代码,您应该确保将其调整回您的特定情况
