我想要一個腳本來編輯產品,但我一直沒有能夠寫或找到一個腳本,將工作。我已經設法創建腳本以從託管站點爲PhpMyAdmin的數據庫中刪除產品。Php腳本來編輯產品
<?php
function renderForm($id = '', $name = '', $description = '', $genre = '', $price = '', $image = '', $error = '')
{
?>
<!DOCTYPE HTML >
<html>
<head>
<title>New Product</title>
</head>
<body>
<?php
if ($error != '')
{
echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>';
}
?>
<form action="" method="post">
<div>
<strong>id: </strong> <input type="text" name="id" value="<?php echo $id; ?>" /><br/>
<strong>name: </strong> <input type="text" name="name" value="<?php echo $name; ?>" /><br/>
<strong>description: </strong> <input type="text" name="description" value="<?php echo $description; ?>" /><br/>
<strong>genre: </strong> <input type="text" name="genre" value="<?php echo $genre; ?>" /><br/>
<strong>price: </strong> <input type="text" name="price" value="<?php echo $price; ?>" /><br/>
<strong>image: </strong> <input type="text" name="image" value="<?php echo $image; ?>" /><br/>
<th>id</th>
<th>name</th>
<th>description</th>
<th>genre</th>
<th>price</th>
<th>image</th>
<p>ALL FIELDS ARE REQUIRED!</p>
<input type="submit" name="submit" value="Submit">
</div>
<p><a href='view.php'>Back</a></p>
</form>
</body>
</html>
<?php
}
include('connect-db.php');
if (isset($_POST['submit']))
{
// get form data, making sure it is valid
$id = mysql_real_escape_string(htmlspecialchars($_POST['id']));
$name = mysql_real_escape_string(htmlspecialchars($_POST['name']));
$description = mysql_real_escape_string(htmlspecialchars($_POST['description']));
$genre = mysql_real_escape_string(htmlspecialchars($_POST['genre']));
$price = mysql_real_escape_string(htmlspecialchars($_POST['price']));
$image = mysql_real_escape_string(htmlspecialchars($_POST['image']));
// check to make sure the fields are entered
if ($id == '' || $name == '' || $description == '' || $genre == '' || $price == '' || $image == '')
{
// generate error message
$error = 'ERROR: Please fill in all required fields!';
renderForm($id = '', $name = '', $description = '', $genre = '', $price = '', $image = '', $error = '');
}
else
{
// save the data to the database
mysql_query("INSERT product SET id='$id', name='$name', description='$description', genre='$genre', price='$price', image='$image'")
or die(mysql_error());
// once saved, redirect back to the view page
header("Location: view.php");
}
}
else
{
renderForm('','','');
}
?>
編輯腳本的目的是爲了節省必須刪除產品的時間,並在網站上再次添加產品。
<形式行動= 「」 方法= 「POST」>需要添加的動作。例如'
首先使用Php錯誤報告和chk錯誤,這不是更新語句。 – devpro
@devpro「更新」,你的意思是他們的'INSERT產品SET ...'?這是有效的語法。 http://dev.mysql.com/doc/refman/5.7/en/insert.html - 如果他使用了'WHERE'子句,那麼這將是一個不同的故事。 –
