Question

我有一个插入多条记录的表格。

该表单具有：字段用户名（A），BTR（B），使用的设施（C），样品数（D）以及与不同样品相关的记录（1,2,3 ..）。

使用此表单，我将多个记录（ABCD1，ABCD2，ABCD3，ABCD4 ...插入数据库中。

我尝试使用for循环，但它保存了最后一个记录值。我无法做到，请帮助我。

 if(isset($_POST['add']))
    {
    $user=$_POST['user'];
    $btr=$_POST['btr'];
    $facility=$_POST['facility'];
    $type=$_POST['type'];
    $samplelocation=$_POST['samplelocation'];
    $remarks=$_POST['remarks'];
    $samplecount=$_POST['samplecount'];
    $sql="INSERT INTO  tblfacility(user,btr,facility,type,samplelocation,remarks) VALUES(:user,:btr,:facility,:type,:samplelocation,:remarks)";
    $query = $dbh->prepare($sql);
    $query->bindParam(':user',$user,PDO::PARAM_STR);
    $query->bindParam(':btr',$btr,PDO::PARAM_STR);
    $query->bindParam(':facility',$facility,PDO::PARAM_STR);
    $query->bindParam(':type',$type,PDO::PARAM_STR);
    $query->bindParam(':samplelocation',$samplelocation,PDO::PARAM_STR);
    $query->bindParam(':remarks',$remarks,PDO::PARAM_STR);
    $query->execute();
    $lastInsertId = $dbh->lastInsertId();
    if($lastInsertId)
    {
    $_SESSION['msg']="Sample Listed successfully";
    header('location:manage-books.php');
    }
    else 
    {
    $_SESSION['error']="Something went wrong. Please try again";
    header('location:manage-books.php');

在所有输入名称中添加[]，例如：name="user[]"。提交后，这将为您提供输入元素的数组。

因此，在您的if(isset($_POST['add']))中，您可以像$arr_user = $_POST['user'];这样获得该数组，然后使用for循环来循环这些数据。您的tr标签可能就像

<tr class="tr-header">
<h4 style="color:darkGreen;" ><b><u>SAMPLE INFORMATION</u></b></h4> 
<th class= "col-md-1" align="centre">Sl.No.</th>
<th class= "col-md-2" align="centre">TYPE OF SAMPLE</th>
<th  class= "col-md-2" align="centre">Sample Location</th>
<th class= "col-md-6" align="centre"> Remarks</th>
<th><a href="javascript:void(0);" style="font-size:18px;" id="addMore" title="Add More Sample"><span class="glyphicon glyphicon-plus"></span></a></th>

<tr>
<td><input type="text"  name="slno[]" value= "<?php echo $i; ?>" class="form-control" ></td> 
<td><select  type="text" name="type[]" class="form-control">
  <option value="SELECT TYPE">SELECT TYPE</option>
   <option value="BONE">BONE</option>
   <option value="CARBONATE">CARBONATE</option>
  </select></td>

<td><input type="text" name="samplelocation[]" class="form-control" ></td>
<td><input type="text" name="remarks[]" class="form-control"></td>

<td><a href='javascript:void(0);'  class='remove'><span class='glyphicon glyphicon-remove'></span></a></td>
<?php }?>
</tr>

使用for循环将多个记录插入数据库
