问题是我无法将HTML数组的输入发布到php数组变量。
X单选按钮组说回答[1]，回答[2] ....回答[x]。 答案[1]有四个值A，B，C，D选择单选按钮值存储在答案[1]中，同样适用于所有答案[2]，....答案[x]。所以基本上我想将每个选定的选项存储在数组中，即在数组位置1处正确回答1，依此类推...... 我试图获得客观问题的答案，并在提交时将其保存到数组变量，然后在单列中插入数据库。
当用户输入问题数（例如10）时，他会得到每个问题的A，B，C，D单选按钮，即A，B，C，D的10倍，并且可以选择正确答案并提交。 然后将所有答案保存在数组中并插入表中。
Html输出显示为......
<tr>
<td>1      <input type="radio" name="answer[1]" value="A">   A   <input type="radio" name="answer[1]" value="B">   B  <input type="radio" name="answer[1]" value="C">   C   <input type="radio" name="answer[1]" value="D">  D

回声中的Php varibale显示Null .. $ tq是问题总数......
if(isset($_REQUEST['Submit']))
{ $x=1;
while($tq>=$x) {
echo "hiii";
$answer_id[] = $_POST['answer[]'] ;$x++;
var_dump( $answer_id[$x]);
}}
<form action="" method="post" enctype="multipart/form-data" name="form1" onsubmit="javascript:return valpass(this);">
<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0">
<tr >
<td class="page-top-outer" ><?php include("header_content.php"); ?></td>
</tr>
<tr>
<td height="500" class="top-inp"><?php include("menu.php"); ?></td>
</tr>
<?php $x=0;
while($tq>0) { $tq--; $x++;
echo '<tr><td>'.$x.'   <input type="radio" name="answer['.$x.']" value="A">  A  <input type="radio" name="answer['.$x.']" value="B">  B  <input type="radio" name="answer['.$x.']" value="C">  C <input type="radio" name="answer['.$x.']" value="D">  D</td></tr>';
}
?>
<input name="Submit" type="Submit" value="Submit">

如果$ tq = 5，则输出为空5次。
答案 0 :(得分：2)
$_POST就像 -
array(
answer => array(
1 => value1,
2 => value2,
.......
)
)
尝试 -
$answers = $_POST['answer'];
foreach ($answers as $answer) {
var_dump($answer);
}
答案 1 :(得分：0)
您可以像这样更新代码并尝试：
