$ _POST在fetch_assoc中具有相同的名称

大家好，今天我得到了一个有趣的问题（至少对我而言）。我正在创建div和输入
在fetch_assoc中，我想知道提交所有这些输入的最佳方法。它们具有相同的名称，但它们具有不同的值，有时相同。

这是代码：

<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
    <form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
        <td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
    <td> <?php echo $row["IDBewoner"] ?> </td>
    <td> <?php echo "<img src='data:image/jpeg;base64,".base64_encode($row['Foto'])."' width='90' height='90'>" ?> </td>

    <td> 
        <div id="rang1" class="DropZone"></div> 
        <input type="hidden" value="" id="rang1input" name="rang1value" />
    </td>
    <td> 
        <div id="rang2" class="DropZone"></div> 
        <input type="hidden" value="" id="rang2input" name="rang2value" />
    </td>
    <td> 
        <div id="rang3" class="DropZone"></div> 
        <input type="hidden" value="" id="rang3input" name="rang3value" />
    </td>
    <td> 
        <div id="rang4" class="DropZone"></div> 
        <input type="hidden" value="" id="rang4input" name="rang4value" />
    </td>
    <td> 
        <div id="rang5" class="DropZone"></div>
        <input type="hidden" value="" id="rang5input" name="rang5value" />
    </td>
    <td> 
        <div id="rang6" class="DropZone"></div> 
        <input type="hidden" value="" id="rang6input" name="rang6value" />
    </td>
    <td> 
        <div id="rang7" class="DropZone"></div> 
        <input type="hidden" value="" id="rang7input" name="rang7value" />
    </td>
    <input type="submit" value="Save">
    </form> 
</tr>

<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {

    /*for($i = 0; $i < $totaalbewoners; $i++) { [!!DANGEROUS CODE!!]
        $rang1bewoner.$i = $_POST["rang1value"][$i];
    }*/ 

    $rang1 = $_POST["rang1value"];
    $rang2 = $_POST["rang2value"];
    $rang3 = $_POST["rang3value"];
    $rang4 = $_POST["rang4value"];
    $rang5 = $_POST["rang5value"];
    $rang6 = $_POST["rang6value"];
    $rang7 = $_POST["rang7value"];
    $bewonerID = $_POST["bewoner"];

    /*echo "<script>alert('Bewoner: $bewonerID')</script>";
    echo "<script>alert('Rang1: $rang1')</script>";
    echo "<script>alert('Rang2: $rang2')</script>";
    echo "<script>alert('Rang3: $rang3')</script>";
    echo "<script>alert('Rang4: $rang4')</script>";
    echo "<script>alert('Rang5: $rang5')</script>";
    echo "<script>alert('Rang6: $rang6')</script>";
    echo "<script>alert('Rang7: $rang7')</script>";*/

}

}
?>

我首先将if $_SERVER["METHOD_REQUEST"]放在fetch_assoc下，但只得到了值
第一排然后我把它放在while fetch_assoc中（正如你在我的代码中看到的那样），但是没有工作
要么一遍又一遍地得到相同的价值观。然后我试着改变输入的名称
到name="rang6value[]"，然后在PHP代码中我使用总行作为一个写for 最大（你可以在php的评论中看到它）和我的浏览器崩溃（这很有趣）。

现在问题是：如何以简单的方式获取输入字段的所有值 所有的行？如果你可以帮助我，我的生活会好得多。

非常感谢您提前。 ^^

更新：插入代码：

如果您希望一个表单将表单标记放在while循环之外

 <?php
        $sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
        $res = mysqli_query($mysqli, $sql);
        $totaalbewoners = mysqli_num_rows($res);
        ?> 
        <form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
        <?php while($row = mysqli_fetch_assoc($res)) {
        ?>
        <tr>

                <td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
            <td> <?php echo $row["IDBewoner"] ?> </td>

                 foreach ($value as $key1 => $value1) {
                  echo $value1 . "<br />";
                 }
            }
    }

尝试修改您的表单以包含您的IDBewoner （无论一个好的独特字段是什么，此字段可能不是唯一的，我不知道，很难说）值在双数组中，类似于：

<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
    <form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
        <td>
            <input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner[]">
        </td>
        <td>
            <?php echo $row["IDBewoner"] ?>
        </td>
        <td>
            <img src="data:image/jpeg;base64,<?php echo base64_encode($row['Foto']); ?>" width='90' height='90'>
        </td>
        <?php for($i=0; $i <= 7; $i++) {
            $owner_id   =   $i.$row["IDBewoner"]; ?>
        <td> 
            <div id="rang<?php echo $owner_id; ?>" class="DropZone"></div> 
            <input type="text" value="" id="rang<?php echo $owner_id; ?>input" name="rang[<?php echo $row["IDBewoner"]; ?>][<?php echo $i; ?>]" />
        </td>
        <?php }
    } ?>
        <td>
             <input type="submit" name="submit" value="submit" />
        </td>
    </form>
</tr>

会给你一个类似于的数组（我没有填写任何值，因为它们都是空白的）：

                )

        )

    [submit] => submit
)

这是你处理sql的方法。请注意，您应该清理或绑定值，但我没有包含这样的内容：

<?php

if(isset($_POST["submit"])) {
    $sql['cols']    =   "INSERT INTO `ActiviteitenSchema` (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";
    $i = 0;
    foreach($_POST['rang'] as $key => $value) {             

            $z = 0;

这是你想要做的吗？

$values = array;
for ($i=1; $i<=7; $i++)
{ 
   $values [$i] = $_POST["rang".$i."value"];
}

那怎么样？假设你的输入有id1 own1rang1value，own1rang2value等

$values = array; 
for ($owner=1; $owner<=7; $owner++)
{
   $rec = array;
   for ($i=1; $i<=7; $i++)
   { 
      $rec [$i] = $_POST["own".$owner."rang".$i."value"];
   }
   $values[$owner]=$rec;
}

插入代码：

<?php

if(isset($_POST["submit"])) {
    $sql['cols']    =   "INSERT INTO ActiviteitenSchema (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";

    $i = 0;
    foreach($_POST['rang'] as $key => $value) {             
        $z = 0;
        foreach($value as $rang) {
            if(!empty($rang)) {
                    $vals[$i][] = "(4, '".$_POST['bewoner'][$i]."', '".$rang."', '2015-04-14', '$z')";
            }
            $z++;
        }

        if(isset($vals[$i])) {
            $sql['vals'][]  =   implode(", ",$vals[$i]);
        }
        $i++;
    }

    if(isset($sql['vals'])) {
        $statement  =   $sql['cols'].implode(", ",$sql['vals']);
        $res        =   $mysqli->query($statement);
        echo "<script>alert('gegevens zijn toegevoegd')</script>";
        header("Location: nieuwschema.php");
    }
}

?>



fetch_assoc：

<div id="MainDiv">
  <div id="ListBewoners">
      <table id="ListBewonersUL">

      <?php
      $sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
      $res = mysqli_query($mysqli, $sql);
      $totaalbewoners = mysqli_num_rows($res);
      while($row = mysqli_fetch_assoc($res)) {
      ?>
      <tr>
          <form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
              <td>
                  <input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner[]" size="2">
              </td>
              <td>
                  <?php echo $row["IDBewoner"] ?>
              </td>
              <td>
                  <img src="data:image/jpeg;base64,<?php echo base64_encode($row['Foto']); ?>" width='90' height='90'>
              </td>
              <?php for($i=0; $i < 7; $i++) {
                  $owner_id   =   $i.$row["IDBewoner"]; ?>
              <td> 
                  <div id="rang<?php echo $owner_id; ?>" class="DropZone"></div> 
                  <input type="text" value="" id="rang<?php echo $owner_id; ?>input" name="rang[<?php echo $row["IDBewoner"]; ?>][<?php echo $i; ?>]" />
              </td>
              <?php }
          } ?>
      </tr><tr>
              <td>
                   <input type="submit" name="submit" value="Save" />
              </td>
          </form>
      </tr>


  </table>
  </div>
</div>

我将操作设为PHP_SELF，并将插入代码放在底部的同一页面中。
