注意:未定义的索引:使用<;选择>;


Notice: Undefined index: While using <select>

好的,这是代码

PHP:

 $rgen        = mysql_real_escape_string(strip_tags($_POST['gender']));
 $dobm        = mysql_real_escape_string(strip_tags($_POST['dobm']));
 $dobd        = mysql_real_escape_string(strip_tags($_POST['dobd']));
 $doby        = mysql_real_escape_string(strip_tags($_POST['doby']));
 $dab         = $doby.$dobm.$dobd;

 $tos         = mysql_real_escape_string(strip_tags($_POST['TOS']));  

HTML:

    <select id=ftxti name=gender style="width:130px; padding: 10px 15px; height: 52px;" >
        <option disabled selected >I'am</option>
        <option value=0 >Male</option>
        <option value=1 >Female</option>
    </select>
    <td>
</tr>
<tr>
    <td class=dob >
    <select name="dobm" id=ftxti style="width:103px;" >
        <option disabled selected >Month</option>
        <?php for ($i = 1; $i <= 12; $i++) : ?>
            <option value="<?php echo ($i < 10) ? '0'.$i : $i; ?>"><?php echo $i; ?></option>
        <?php endfor; ?>
    </select>
    <select name="dobd" id=ftxti style="width:95px;" >
        <option disabled selected >Day</option>
        <?php for ($i = 1; $i <= 31; $i++) : ?>
            <option value="<?php echo ($i < 10) ? '0'.$i : $i; ?>"><?php echo $i; ?></option>
        <?php endfor; ?>
    </select>
    <select name="doby" id=year style="width:95px;" >
        <option disabled selected >Year</option>
            <?php for ($i = 1980; $i < date('Y'); $i++) : ?>
                <option value="<?php echo $i; ?>"><?php echo $i; ?></option>
            <?php endfor; ?>
    </select>
<label >
    <div id=tosag >
        <input type=checkbox name=TOS value=1 />
        <font style="font-size: 11px;" >
          I agree to <a href=# style="color: rgb(50, 92, 129);">TOS</a>
        </font>
    </div>
</label>

错误:

如有任何帮助,我们将不胜感激。问题是,我似乎已经定义了索引,但我这里一定缺少一条规则,我对PHP有点生疏,所以请对我温和一点,而且我也是新来的,所以如果我做错了什么,我很抱歉。。。

如果没有看到所有的代码,很难猜测。。。但我会先检查一下,确保你的表格方法设置为张贴。

我以为Html和Php都在同一页上。在没有提交表单的情况下加载HTML页面时,所有PHP变量都是空的。就是这样。你需要这样写。

  if(isset($_POST['gender'])){
  $rgen = mysql_real_escape_string(strip_tags($_POST['gender']));
  }

另一种方式,如果你想隐藏通知&警告,您可以在页面顶部添加以下代码。我不会在开发环境中建议这样做。

   error_reporting(0);
     (or) 
   ini_set( "display_errors", 0);

这可能不会解决任何问题。。。但你可能是想让<td>成为</td>

    <select id=ftxti name=gender style="width:130px; padding: 10px 15px; height: 52px;" >
        <option disabled selected >I'am</option>
        <option value=0 >Male</option>
        <option value=1 >Female</option>
    </select>
    <td>   <----- This should probably be a closing tag!
</tr>

你还应该在你的属性周围添加引号:

<a href=#  should be <a href="#"
or
id=ftxti should be id="ftxti"
or
<option value=1 > should be <option value="1" >
