大家好,我的標題告訴我正在做一個動態輸入,但我有錯誤,我要哭了哈哈。說真的,我很難做到。我想添加動態輸入並在我的數據庫中添加值。這裏是我的代碼:動態輸入並將其添加到數據庫
<?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);
?>

我在環路已經的問題,我得到這個錯誤:
警告:mysqli_fetch_array()預計參數1被mysqli_result,在C中給出 布爾:\瓦帕\ WWW \測試\動態外形fields.html.php上 線51這是在前面的代碼行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;?>
感謝SUP港口!
編輯
這裏你們幫助我的代碼的新的部分:但沒有當我向數據庫提交情況。我檢查了我的數據庫的phpmyadmin。

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
$sql="SELECT * FROM recherche ORDER BY id";
$result = $link->query($sql);

在這裏finfinaly是偉大的人在這個論壇上的結果!
隨意編輯或做任何你想要的代碼!

感謝這個部分它的工作,但最後我真的不知道如何做到這一點,代碼\t //添加新的搜索記錄 \t if(!empty($ _ POST ['name'])){ \t // \t($ i = 0; $ i query($ sql); \t \t} \t} \t' –

@TheBaconManWithouBacon,如果我沒有錯那麼,你想添加多行數據庫表單提交,對嗎? –
是的當我提交他在輸入(動態)輸入的客戶端的所有數據將被添加到數據庫。例如,如果他想在添加5行時添加5個名稱,並且當他在數據庫中完成時,保存1-名 - 第二個名... – TheBaconManWithouBacon
