Php 将行和动态文本框插入mysql

我需要您的帮助，从一个表和动态文本字段中获取行，然后将其插入另一个表中。我想做的是从下表中获取一些特定的状态id，结合同一页上显示的文本框中的数据，然后插入到表中

                    +---------+--------------------------+
                    |state_id |  state   |   senatorial  |  
                    |--- -----|----------|---------------|
                    |    1    |  utah    |    A-North    | 
                    |    2    |  utah    |    B-South    |  
                    +---------+----------+---------------+

                    <?php
$constituencys = $_POST['constituency']      ; 
        $state_id = $_POST['state_id']; 


         if(isses($_POST['constituency']))
   {
$constituencys = $_POST['constituency']      ;   
                      foreach($constituencys as          $constituency) {  
     $state_id[$i]= $state_id[$i];
                      $query = mysql_query(" 
         INSERT INTO `constituency` (
                    `constituency_id`,
                    `state_id`,
                    `constituency_name`
                    ) VALUES (
                    NULL,
                    '".$state_id[$i]."',
                    '".$constituency."'
                    "); 
                       }



                    if(mysql_affected_rows()>0){
                    echo "Inserted Successfully";
                    }else{
                    echo "No Row Inserted";
                    echo mysql_error() ;
                    echo"<br>Error:".mysql_error();
                   echo"<br>Query:".$query; 
      } } ?>

我用来获取信息的HTML。“选区”是一个动态文本字段，多次出现，因此需要将其放入数组中

                    <input type='hidden' name="state_id[]"   value="<?php echo $row['state_id'];?>" />
                    <input type='text'   name='constituency[]' />

当我运行代码时，没有插入行 显示在屏幕上

请帮帮我。 非常感谢，谢谢

显示错误

先试试这段代码，用结果更新你的帖子

更新

看起来您可能有“脏”输入。请确保在插入mysql之前，通过使用对其进行清理。请尝试以下代码

<?php
$constituencys = $_POST['constituency']; 
$state_id = $_POST['state_id']; 

$i = 0;
while($i<count($constituencys)){
    $constit = mysql_real_escape_string($constituencys[$i]);
    $state = mysql_real_escape_string($state_id[$i]);
    $query = "INSERT INTO `constituency` ( 
        `constituency_id`, `state_id`, `constituency_name`
        ) VALUES (
        NULL,
        '$state',
        '$constit')
        "; 

    mysql_query($query);          
    $i++;  
}

if(mysql_affected_rows()>0){
    echo "Inserted Successfully";
} else {
    echo "No Row Inserted";
    echo "<br><br>Error: " . mysql_error();
    echo "<br><br>Query: " . $query;
} 
?>

注意：在查询的末尾，缺少一个右括号。它已添加到第二个示例中。在继续测试之前，确保它在那里

<?php
$constituencys = $_POST['constituency']; 
$state_id = $_POST['state_id']; 

$query = "INSERT INTO `constituency` (`constituency_id`, `state_id`, `constituency_name`) VALUES";

for($i=0; $i<count($constituencys); $i++){
    $constit = mysql_real_escape_string($constituencys[$i]);
    $state = mysql_real_escape_string($state_id[$i]);
    $query .= "(NULL, '$state', '$constit'), "; 
}
$query = substr(trim($query), 0, -1); //trims then removes trailing comma
mysql_query($query);          

if(mysql_affected_rows()>0){
    echo "Inserted Successfully";
} else {
    echo "No Row Inserted";
    echo "<br><br>Error: " . mysql_error();
    echo "<br><br>Query: " . $query;
} 
?>

假设您的HTML输入被正确地设置为数组，这应该可以工作。它还整理您的代码，帮助您消除不必要的延迟。每毫秒计算一次如果这不起作用，请发布返回的错误并再次查询。

mysql已被弃用，帮助有限。请使用mysqli或PDO，您将获得更多帮助。您对SQL注入攻击非常开放。在读懂并解决此问题之前，请停止处理此代码。打开错误报告或检查error.log文件，我确信某个地方存在mysql错误。如果没有插入echo行；，写下它的错误；ifisArray$_POST['substitution']{$substituencys=$_POST['substitution']；$state_id=$_POST['state_id']；}其他{$substituencys[0]=$_POST['substituency']；$state_id][0]=$_POST['state_id']}你喜欢这个吗谢谢。。。现在它正在插入，但只插入一行，而不是2或3行（视情况而定）。如果要插入多行，则仅插入HTML中的第一个值。我能做什么？谢谢。。。谢谢你的帮助。我这样解决了这个问题。请看更新的帖子。@user1378680别担心，很高兴我能帮上忙。
