我创建了一个包含多个复选框和一个包含所有 50 个状态的多个下拉列表的表单。我想从下拉表单中选择多个复选框和多个状态。我的问题当然是我......
所以当我查询我需要的信息时，它会出现空白。我可能会以错误的方式处理这一切。

<form name="search_form" method="post" action="event_list">
  <table>
    <tr>
      <td>Venue</td>
      <td><input type="checkbox" name="AAC" action="" value="AAC"/>
        <label >AAC</label>
        <br />
        <input type="checkbox" name="AKC" action="" value="AKC"/>
        <label >AKC</label>
        <br />
        <input type="checkbox" name="ASCA" action="" value="ASCA"/>
        <label >ASCA</label>
        <br />
        <input type="checkbox" name="CKE" action="" value="CKE"/>
        <label >CKE</label>
        <br />
        <input type="checkbox" name="CPE" action="" value="CPE"/>
        <label >CPE</label>
        <br />
        <input type="checkbox" name="DOCNA" action="" value="DOCNA"/>

        <label >NADAC</label>

您应该尝试用“info[]”替换每个名称，但保留您拥有的值。这是一个示例代码：

<form action="test.php" method="post">
<input type="checkbox" name="check_list[]" value="value 1">
<input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
            echo $check; //echoes the value set in the HTML form for each checked checkbox.
                         //so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
                         //in your case, it would echo whatever $row['Report ID'] is equivalent to.
    }
}
?>
