没有为按钮数组返回值

Question

我有一个$ _POST数组的提交按钮，隐藏，cbo和文本，当我在发布后循环遍历该数组时，无论设置什么，它只会返回数组的最后一个。

已经尝试过isset，然后遍历数组

$i=0;
while($row = mysql_fetch_array($result)){
    $body .= "$<input type='text' name='txtOTHER_INCOME_AMT' value='" . 
                $row['INCOME_AMT'] . "'>                                                                                 
            <input type='submit' name='cmdUpdateIncome' value='Update'>                                                                                                                                  
            <input type='hidden' name='income_id' value='" . $row['INCOME_ID'] . "'>";
    $i++;
}

//check and see if the user is trying to update an OTHER INCOME
if ($_POST['cmdUpdateIncome'] != "" && $_POST['updateincome_id'] != "") {
    for ($i=0; $i>count($_POST['cmdUpdateIncome']); $i++){
        if (isset($_POST['cmdUpdateIncome'])){
                   //do some stuff
        }
    }   
}

如果用户单击n个按钮中的第三个，我想从与所选按钮相关的表单中获取这些字段的值：

txtOTHER_INCOME_AMT和income_id（数据库中的密钥，以便我可以根据txtOTHER_INCOME_AMT中提供的内容进行更新）。

print_r($_POST)给予

        [0] => F4 
        [1] => F1 
        [2] => M3 
        [3] => F2
