我正在使用多选来获取一些值。这个多选使用的是 Chosen jQuery 插件。

出于某种原因，在 PHP 中，此多选返回所有值，而不仅仅是选定的值。

的HTML

<select name="taglist[]" size="10" id="taglist" style="width:350px;" class="chzn-select" multiple multiple-data-placeholder="Select some tags" >
**This is populated by Ajax**
</select>

阿贾克斯人口之后

<option value="Student community of reflection - A conscious environment of cooperative sharing of ideas and proces">Student community of reflection - A conscious environment of cooperative sharing of ideas and proces</option>
<option value="Teacher inclusive conversations - Emphasis on a sharing of power with students; visibility that enco">Teacher inclusive conversations - Emphasis on a sharing of power with students; visibility that enco</option>
<option value="Teacher feedback - Awareness of the power of written, oral and symbolic feedback on students self co">Teacher feedback - Awareness of the power of written, oral and symbolic feedback on students self co</option>
<option value="Student self assessment ( metacognitive reflection) - Continuous opportunities for students to thin">Student self assessment ( metacognitive reflection) - Continuous opportunities for students to thin</option>

PHP的

foreach ($_REQUEST['taglist'] as $value)
{
mysql_query("INSERT INTO recent_tags (t_name, t_owner, t_post) VALUES ('$value', '$uid',  '$id')") or die (mysql_error());
}

结果

Array ( [0] => 学生反思社区 - 有意识地合作分享想法和过程的环境 [1] => 教师包容性对话 - 强调与学生分享权力；可见性 [2] => 教师反馈- 意识到书面、口头和符号反馈对学生自我合作的力量 [3] => 学生自我评估（元认知反思） - 学生不断有机会瘦身）

即使在多选框中仅选择了其中一个选项，也会发生这种情况

希望有人能够帮助解决这个问题，这让我很头疼。

print_r($_POST) 的结果

Array ( [entry_name] => aaa [entry_content] => [tag_category] => Insider Classroom Framework [taglist] => Array ( [0] => Student community of reflection - A conscious environment of cooperative sharing of ideas and proces [1] => Teacher inclusive conversations - Emphasis on a sharing of power with students; visibility that enco [2] => Teacher feedback - Awareness of the power of written, oral and symbolic feedback on students self co [3] => Student self assessment ( metacognitive reflection) - Continuous opportunities for students to thin ) [button] => Post )

我认为您的 HTML 已关闭。你有：

<select name="taglist[]" size="10" id="taglist" style="width:350px;" class="chzn-select" multiple multiple-data-placeholder="Select some tags" >
**This is populated by Ajax**
</select>

而且我看不到您的“内部复选框”的外观，但我几乎可以肯定您没有将它们设置为name='taglist[]'，因为您希望它们具有该值，并且您不希望您的name选择是taglist[]。

如果您使用的是列表，那么您希望将选择名称保留为taglist[]，但不想命名任何内部选项，只需使用它们value的 's.

编辑： 显示所有代码，并且工作正常：

<form action="" method="post">
<select name="taglist[]" size="10" id="taglist" style="width:350px;" class="chzn-select" multiple multiple-data-placeholder="Select some tags" >
<option value="Student community of reflection - A conscious environment of cooperative sharing of ideas and proces">Student community of reflection - A conscious environment of cooperative sharing of ideas and proces</option>
<option value="Teacher inclusive conversations - Emphasis on a sharing of power with students; visibility that enco">Teacher inclusive conversations - Emphasis on a sharing of power with students; visibility that enco</option>
<option value="Teacher feedback - Awareness of the power of written, oral and symbolic feedback on students self co">Teacher feedback - Awareness of the power of written, oral and symbolic feedback on students self co</option>
<option value="Student self assessment ( metacognitive reflection) - Continuous opportunities for students to thin">Student self assessment ( metacognitive reflection) - Continuous opportunities for students to thin</option>
</select>
<input type="submit">
</form>
<?php
if($_REQUEST['taglist']) {

    foreach ($_REQUEST['taglist'] as $value)
    {
        echo $value ."<br>\n";
    }
}
?>
