Javascript 具有相同名称属性的复选框和其他文本框组？,javascript,php,jquery,html,Javascript,Php,Jquery,Html,假设我有几个复选框选项： <p class='question'>Reasons why it is down. Click as many as apply.</p> <input type='checkbox' name='production-down' value='Decrease in demand' required>Decrease in demand <br> <input type='checkbox' name='pro

假设我有几个复选框选项：

<p class='question'>Reasons why it is down. Click as many as apply.</p>
<input type='checkbox' name='production-down' value='Decrease in demand' required>Decrease in demand <br>
<input type='checkbox' name='production-down' value='Expected Decrease in demand'>Expected Decrease in demand <br/>
<input type='checkbox' name='production-down' value='Technical difficulties in production'>Technical difficulties    in production <br/>
<input type='checkbox' name='production-down' value='Shortage in raw materials'>Shortage in raw materials <br/>
<input type="checkbox" name="production-down" value='other' />Other
<input id='productionDownOther' name='other-production-down' type='text'/>

复选框。我是否应该为

#productionDownOther

文本框指定与复选框相同的名称属性？应该是这样吗

我计划使用php方法

内爆

将所选值添加到一起，并将其插入数据库的一列中

请告诉我我的计划是否错误，如果是/否，请告诉我原因。我是个网络开发新手。仍然期待学习。

只需将名称属性更改为数组：

<input type='checkbox' name='production-down[]' value='Decrease in demand' required>Decrease in demand <br>
<input type='checkbox' name='production-down[]' value='Expected Decrease in demand'>Expected Decrease in demand <br/>
<input type='checkbox' name='production-down[]' value='Technical difficulties in production'>Technical difficulties    in production <br/>
<input type='checkbox' name='production-down[]' value='Shortage in raw materials'>Shortage in raw materials <br/>
<input type="checkbox" name="production-down[]" value='other' />Other
<input id='productionDownOther' name='other-production-down' type='text'/>

首先，您想允许多个选项吗？或者一次只允许一个复选框。如果是第一个选项，则需要在每个复选框名称的末尾添加

[]

，以便

生产停止

变为

生产停止[]

。这样，PHP将把所有值放入一个数组中，而不是用下一个值覆盖上一个值。如果只需要一个选项，请将

type=“checkbox”

更改为

type=“radio”

至于您的其他选项，您可以这样做：

<?php $other = null; if (in_array('other', $_POST['production-down']) || $_POST['production-down'] == 'other') { $other = $_POST['other-production-down']; } // database stuff here

您必须使用名称作为数组来实现以下目的 <html> <head> <?php if(isset( $_POST['production-down'])) { $name = $_POST['production-down']; foreach ($name as $color){ if($chk == "other" ) $chk=$_POST['production-down-name']; echo $chk."<br />"; } }?> </head> <body> <form method="POST"> <p class='question'>Reasons why it is down.
