我的目标是打开一个字段，以添加与用户输入的数据一样多的数据，并批量保存此数据
<?php
$connect = new mysqli('localhost','root','','not_impossible');
if(isset($_POST['submit'])){
$adet = $_POST['veri'];
if($adet<=5 && $adet>0){
echo <<<HTML
<form action='' method='POST' align='center'>
<table align='center'>
<tr style='border:none;background-color:black; color:white;'>
<th>Yazılım İsmi</th>
<th>Yazılımcı</th>
<th>Cinsiyet</th>
<th>Yazılım Fiyatı</th>
</tr>
HTML;
$number = 0;
while($number<$adet){
echo <<<HTML
<tr>
<td><input type='text' name='x1' required></td>
<td><input type='text' name='x2'></td>
<td><input type='radio' value='Erkek' name='x3'>Erkek <input type='radio' value='Kadın' name='x3'>Kadın</td>
<td><input type='text' name='x4'></td>
</tr>
HTML;
$number++;
}
echo "</table>";
echo "<input type='submit' style='border:none;border-radius:2px;font-family:calibri;font-size:18px;width:150px;' name='ekle' value='Verileri Ekle'>".' '."<input type='reset' style='border:none;border-radius:2px;font-family:calibri;font-size:18px;width:150px;' value='Verileri Sil'>";
echo "</form>";
}
else{
header('Refresh:2,url=index.php');
echo "<h1>Girdiğiniz rakam 5 ten büyük olamaz</h1>";
}
}
else{
echo <<<HTML
<form action='' method='POST'>
<table>
<tr>
<td>Kaç adet veri girmek istiyorsunuz ?</td>
<td><input type='text' name='veri' required></td>
<td><input type='submit' style='border:none;border-radius:2px;background-color:black;color:white;font-size:18px;font-family:calibri;' name='submit'></td>
</tr>
</table>
</form>
HTML;
}
if(isset($_POST['ekle'])){
$sql = $connect->prepare("insert into yazilim (yazilim_ismi,yazilimci,cinsiyet,yazilim_fiyat) values(?,?,?,?)");
$sql->bind_param('sssi',$_POST['x1'],$_POST['x2'],$_POST['x3'],$_POST['x4']);
$sql->execute();
echo $sql->affected_rows.'Veriler Eklendi';
}
?>我想使用form方法添加多个数据，但是数据没有正确添加到表中。我想将数据正确并顺序地添加到数据库中的表中，但是我无法弄清楚，并且我不完全了解复选框控制方法]
