Question

这是loop.php代码

$compo = $_POST['compo'];
$fill = $_POST['fill'];

$totalCompo = sizeof($compo);

for($i=0;$i<$totalUsername;$i++) {

    $InsertUsername = $compo[$i];
    $InsertFname = $fill[$i];

      $query = "INSERT INTO `Invantsion`(`compon`, `Num`)".
             " VALUES ('$InsertUsername','$InsertFname') ";

}


if ($mysqli->query($query) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $query . "<br>" . $conn->error;
}

在循环页面中我需要插入数据。这是表格在mysql中我看到了mysql的最后一个结果

<form method="POST" action="loop.php">
<input type="hidden" name="step" value="save">
<input type='hidden' name='compo[]' value='DECODERS'>DECODERS<select name='fill[]'><option value='NULL'>null</option></select><br><input type='hidden' name='compo[]' value='DECODERS'>DECODERS<select name='fill[]'><option value='100'>100</option></select><br><input type='hidden' name='compo[]' value='rg59'>rg59<select name='fill[]'><option value='300'>300</option><option value='400'>400</option></select><br><input type="submit" value="שלח" name="ok" style="border: 1px solid #000000; padding-left: 4px; padding-right: 4px; padding-top: 1px; padding-bottom: 1px; background-color: #008000; font-family:Arial; font-size:8pt; font-weight:bold"><input type="reset" value="&agrave;&eacute;&ocirc;&aring;&ntilde;" name="B2" style="border: 1px solid #000000; padding-left: 4px; padding-right: 4px; padding-top: 1px; padding-bottom: 1px; background-color: #008000; font-family:Arial; font-size:8pt; font-weight:bold">
</p>
</form>

我的意思是

<input type='hidden' name='compo[]' value='rg59'>rg59<select name='fill[]'><option value='300'>300</option><option value='400'>400</option>

什么错了？

在查询中使用之前，应检查并清理参数和变量。

您可以利用php中的字符串连接，并使用多个值行构建查询以插入数据。这样，所有数据都将通过单个查询执行来插入。

    $_POST['compo'] = array('test1','test2','test3');
    $_POST['fill'] = array('fname1','fname2','fname3');
    $compo = (!empty($_POST['compo'])?$_POST['compo']:array());
    $fill = (!empty($_POST['fill'])?$_POST['fill']:array());

    $totalCompo = sizeof($compo);

    $query = "INSERT INTO Invantsion(compon, Num) VALUES ";

    for($i=0; $i< $totalCompo; $i++)
    {

     $InsertUsername = (!empty($compo[$i])?$compo[$i]:'');
     $InsertFname = (!empty($fill[$i])?$fill[$i]:'');

     //Only insert if both username and firstname exists
     if(!empty($InsertUsername) && !empty($InsertFname))
     {
       $query .= " ('".$InsertUsername."','".$InsertFname."'), ";
     }
    }

    //Remove the extra , from the end of the query string
    $query = rtrim($query,', ');

    if ($mysqli->query($query) === TRUE) {
       echo "New record created successfully";
    } else {
       echo "Error: " . $query . "<br>" . $conn->error;
    }

从表单到mysql插入多个值
