我的 php 不适用于元素 td，但没有它也能正常工作

Question

我在“echo with td elements”上遇到问题，仅在表单的第一个选择上，因为我拥有的其他代码只有在第一个选择有效时才能正常工作....

那么，这就是我的代码：

$stallFirstSel=oci_parse($conn, 'SELECT * FROM ACTIVIDAD');
oci_execute($stallFirstSel);
echo "<table><tr>";
echo "<td><form id='formActis' method='POST' action='reserves_es.php'>";
echo "<select name='selActi[]'>";
while (($row=oci_fetch_array($stallFirstSel,OCI_BOTH))!=false){
      echo "<option id='optActi'>".$row['NOM']."</option>";
}
echo "</select>";
echo "<td><input type='submit' value='Enviar'></td>";
echo "</form></td></tr>";

如果我修改它删除所有 td 标签，它运行良好，所有其他代码也运行，因为我有条件 if(isset($_POST['selActi'])):

$stallFirstSel=oci_parse($conn, 'SELECT * FROM ACTIVIDAD');
oci_execute($stallFirstSel);
echo "<table><tr>";
echo "<form id='formActis' method='POST' action='reserves_es.php'>";
echo "<select name='selActi[]'>";
while (($row=oci_fetch_array($stallFirstSel,OCI_BOTH))!=false){
      echo "<option id='optActi'>".$row['NOM']."</option>";
}
echo "</select>";
echo "<input type='submit' value='Enviar'>";
echo "</form></tr>";

仅此而已，如果有人可以帮助我或知道如何解决吗？谢谢

Answer 1

你在 while { } 之后错过了一个（结束标签）

Answer 2

您正在递归地使用<td> 标记，而没有指定新的<table>。

这是您的清晰代码。

$stallFirstSel=oci_parse($conn, 'SELECT * FROM ACTIVIDAD');
oci_execute($stallFirstSel);
echo "<form id='formActis' method='POST' action='reserves_es.php'>";
echo "<table>";
    echo "<tr>";
        echo "<td>";
            echo "<select name='selActi[]'>";
            while (($row=oci_fetch_array($stallFirstSel,OCI_BOTH))!=false){
                  echo "<option id='optActi'>".$row['NOM']."</option>";
            }
            echo "</select>";
        echo "</td>";
        echo "<td>";
            echo "<input type='submit' value='Enviar'>";
        echo "</td>";
    echo "</tr>";
echo "</table>";
echo "</form>";
