我一直在寻找这个问题的解决方案，但没有运气。基本上，当在表格中插入项目时，它不会返回结果（不会插入任何内容）。我检查了表格字段和所有匹配项，我似乎无法找到我正在做的错误。
这是我目前所拥有的代码部分，问题出现在哪里。

如果有人能提供帮助，我真的很感激！
编辑：将$$ component_name更改为$ component_name。 （错字）
编辑：整页代码。

答案 0 :(得分：0)
首先，当你创建一个表...得到一个查询结果......我认为应该是这样的：
<div class = "mytable">
<?php
$queryComp_Type = "select id, name from conc_type order by name";
$resultadoQueryComp_Type = mysqli_query($conn, $queryComp_Type);
$tableHeader = "";
$tableBody = "";
?>
<table>
<thead>
<?php
while ($row = mysqli_fetch_array($resultadoQueryComp_Type)) {
$tableHeader .= '<tr>
<th>'.$row['name'].';</th>
</tr>';
}
?>
<?=$tableHeader?>
</thead>
<tbody>
<?php
while ($row = mysqli_fetch_array($resultadoQueryComp_Type)) {
$tableBody .= '<tr>
<td>'.$row['id'].'</td>
</tr>';
}
?>
<?=$tableBody?>
</tbody>
</table>
</div>
