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，这种多选返回所有值，而不仅仅是所选的值。
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>
Ajax填充后
<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
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-一个有意识的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；enco[2]的可见性=>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）-学生不断减少的机会
即使在多选框中只选择了其中的一个选项，也会发生这种情况
希望有人能帮上忙，这让我头疼。
打印_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 )
表单张贴
<form id="form1" name="form1" method="post" onSubmit="return checkAll();" action="process/webpl_journal_entry_process.php">
我想你的HTML已经关闭了
<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>
我看不出你的"内部复选框"是什么样子的，但我几乎可以肯定，你没有把它们作为name='taglist[]'，因为你希望它们携带这个值，你也不希望你选择的name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[]，但不希望命名任何内部选项，只需使用它们的value。
编辑：显示所有代码，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" >
