Question

我有

<form action="entry.php" method="post" >
<table>
<tr>
    <td>
        <input type="text" name="searchid[]" id="searchid" placeholder="Data 1" ><br />
        <input type="text" name="searchid[]" id="searchid" placeholder="Data 2" ><br />
        <input type="text" name="searchid[]" id="searchid" placeholder="Data 3" ><br />
        <input type="text" name="searchid[]" id="searchid" placeholder="Data 4" ><br />
    </td>
</tr>
<tr>
<td><input type="submit" name="submit" id="submit" value="submit" /></td>
</tr>

</table>    
</form>

和entry.php代码，

<?php
include "db.php";

if (isset($_POST["submit"]))

$data1 = mysql_real_escape_string($_POST['searchid']);

$query1 = "INSERT INTO php_test (name) VALUES ('$data1')";
$query = mysql_query($query1,$connection);

if($query){
    header ("location: index.php");
    }
else{
    echo "Something Wrong";
    }

?>

此代码使用单个输入数据，但是，我想在同一列的单独字段中输入四个数据，当我提交时，它会在单独的行中插入数据，字段名称相同并且

Answer 1

$_POST['searchid']是一个数组，而不是一个字符串。你需要循环它们：

if (isset($_POST["submit"]))
    foreach ($_POST['searchid'] as $searchid) {
        $data1 = mysql_real_escape_string($searchid);
        mysql_query("INSERT INTO php_test (name) VALUES ('$data1')") or die(mysql_error());
    }
}
header("location: index.php");

此外，摆脱HTML中的重复id="searchid"属性。 ID必须是唯一的。您可能根本不需要这些元素。

如果您有多列，可以这样做：

if (isset($_POST["submit"]))
    foreach ($_POST['searchid'] as $index => $searchid) {
        $data1 = mysql_real_escape_string($searchid);
        $data2 = mysql_real_escape_string($_POST['searchid2'][$index]);
        mysql_query("INSERT INTO php_test (name, name2) VALUES ('$data1', '$data2')") or die(mysql_error());
    }
}

Answer 2

当你在数组中获得价值时。所以你应该把你的insert语句放在循环中。可能是这样的： -

根据建议你不能mysql_real_escape_string超过数组。因此，您应该从循环内部的顶部和mysql_real_escape_string中删除每个值。

$data1 = $_POST['searchid'];
foreach($data1 as $postValues) {
  $name = mysql_real_escape_string($postValues);
  $query1 = "INSERT INTO php_test (name) VALUES ('$name')";
  $query = mysql_query($query1,$connection);
}

Answer 3

请尝试以下代码：

<?php
   include "db.php";

   if (isset($_POST["submit"]))

   foreach($_POST['searchid'] as $id){          
       $searchid= mysql_real_escape_string($id);
       $query1 = "INSERT INTO php_test (name) VALUES ('$searchid')";
       $query = mysql_query($query1,$connection);
   }
   if($query){
     header ("location: index.php");
   }
   else{
     echo "Something Wrong";
   }

Answer 4

试试这个：

<?php
include "db.php";

if (isset($_POST["submit"]))


foreach($_POST["submit"] as $searchval) {
  $query1 = "INSERT INTO php_test (name) VALUES ('$searchval')";
  $query = mysql_query($query1,$connection);
}

if($query){
  header ("location: index.php");
}
else{
  echo "Something Wrong";
}

?>
