动态输入并将其添加到数据库

大家好，我的标题告诉我正在做一个动态输入，但我有错误，我要哭了哈哈。说真的，我很难做到。我想添加动态输入并在我的数据库中添加值。这里是我的代码：动态输入并将其添加到数据库

<?php 
// Connect to the DB 
$link = mysqli_connect("localhost","root","","testlp") or die("Error " . mysqli_error($link)); 

// store in the DB 
if(!empty($_POST['ok'])) { 
    // first delete the records marked for deletion. Why? Because we don't want to process them in the code below 
    if(!empty($_POST['delete_ids']) and is_array($_POST['delete_ids'])) { 
     // you can optimize below into a single query, but let's keep it simple and clear for now: 
     foreach($_POST['delete_ids'] as $id) { 
      $sql = "DELETE FROM recherche WHERE id=$id"; 
      $link->query($sql); 
     } 
    } 



    // adding new recherche 
    if(!empty($_POST['name'])) { 
    // ($i = 0; $i < count($_POST['name']); $i++) 
     { 
      $sql = "INSERT INTO recherche (name) VALUES ".$_POST['name'][$i]; 
      $link->query($sql); 
     } 
    } 
} 

// select existing recherche here 
$sql="SELECT * FROM recherche ORDER BY id"; 
$result = $link->query($sql); 
?>

    <?php 
    // let's assume you have the product data from the DB in variable called $recherche 
    while($product = mysqli_fetch_array($result)): ?> 
     <p id="oldRow<?=$product['id']?>"> Item name: <input type="text" name="name<?=$product['id']?>" value="<?=$product['name']?>" /> <input type="checkbox" name="delete_ids[]" value="<?=$product['id']?>"> Mark to delete</p>

    jQuery('#itemRows').append(row); 
    frm.add_qty.value = ''; 
    frm.add_name.value = ''; 
} 

function removeRow(rnum) { 
    jQuery('#rowNum'+rnum).remove(); 
} 
</script> 
</body> 
</html>

我在环路已经的问题，我得到这个错误：

警告：mysqli_fetch_array（）预计参数1被mysqli_result，在C中给出布尔：\瓦帕\ WWW \测试\动态外形fields.html.php上线51这是在前面的代码行51

while($product = mysqli_fetch_array($result)): ?> 
     <p id="oldRow<?=$product['id']?>"> Item name: <input type="text" name="name<?=$product['id']?>" value="<?=$product['name']?>" /> <input type="checkbox" name="delete_ids[]" value="<?=$product['id']?>"> Mark to delete</p> 
    <?php endwhile;?>

感谢SUP港口！

这里你们帮助我的代码的新的部分：但没有当我向数据库提交情况。我检查了我的数据库的phpmyadmin。

<?php 
// Connect to the DB 
$link = mysqli_connect("localhost","root","","testlp") or die("Error " . mysqli_error($link)); 

// store in the DB 
if(!empty($_POST['ok'])) { 
    // first delete the records marked for deletion. Why? Because we don't want to process them in the code below 
    if(!empty($_POST['delete_ids']) and is_array($_POST['delete_ids'])) { 

     foreach($_POST['delete_ids'] as $id) { 
      $sql = "DELETE FROM recherche WHERE id=$id"; 
      $link->query($sql); 
     } 
    } 

    // adding new recherche 
    if(!empty($_POST['name'])) { 
    foreach($_POST['name'] as $name) 
    { 
     //escape special characters from inputed "name" to prevent SQL injection. 
     $sql = "INSERT INTO recherche (name) VALUES ".mysqli_real_escape_string($link,$name); 
     $link->query($sql); 
    } 
} 
} 

// select existing recherche here

$result = $link->query($sql);

永远不要假设你在$result数据。测试它处理它。

<?php 
if($result!=false && mysqli_num_rows($result)>0){ 
    while($product = mysqli_fetch_array($result)): ?> 
     <p id="oldRow<?=$product['id']?>"> Item name: <input type="text" name="name<?=$product['id']?>" value="<?=$product['name']?>" /> <input type="checkbox" name="delete_ids[]" value="<?=$product['id']?>"> Mark to delete</p> 
    <?php endwhile; 

} 
?>

FIX这部分代码，以插入形式的多行提交

// adding new recherche 
if(!empty($_POST['name'])) { 
    foreach($_POST['name'] as $name) 
    { 
     //escape special characters from inputed "name" to prevent SQL injection. 
     $sql = "INSERT INTO recherche (name) VALUES ('".mysqli_real_escape_string($link,$name)."')"; 
     $link->query($sql); 
    } 
}

感谢这个部分它的工作，但最后我真的不知道如何做到这一点，代码\t //添加新的搜索记录 \t if（！empty（$ _ POST ['name']））{ \t // \t（$ i = 0; $ i query（$ sql）; \t \t} \t} \t' – TheBaconManWithouBacon

@TheBaconManWithouBacon，如果我没有错那么，你想添加多行数据库表单提交，对吗？ –

是的当我提交他在输入（动态）输入的客户端的所有数据将被添加到数据库。例如，如果他想在添加5行时添加5个名称，并且当他在数据库中完成时，保存1-名 - 第二个名... – TheBaconManWithouBacon
