我在这个问题上跌跌撞撞地走出了困境。我无法让此代码在提交创建产品后立即将用户重定向到其产品页面。我有三个文件 create_product.php |产品.php | & 我正在从中调用函数的外部函数页面。我似乎无法开始工作的是: header("location:product.php?product_id='.$product_id.'");功能。所有内容都正确输入到数据库中,但是当用户单击“提交”来创建产品时,我收到“该产品不存在”错误。任何帮助将不胜感激(我知道存在安全问题等......目前不担心这些问题,而只是获取“创建产品提交按钮以将用户重定向到新创建的产品页面......” .很抱歉回复率低(作为新用户已经引起我的注意......我将开始接受所有答案)。非常感谢您提供的任何帮助,
CREATE_PRODUCT.PHP 页面:
<?php
if (isset($_POST['product_name'], $_POST['product_description'], $_FILES['fileField'])) {
$product_name = $_POST['product_name'];
$product_description = $_POST['product_description'];
$image_name = $_FILES['fileField']['name'];
$image_size = $_FILES['fileField']['size'];
$image_temp = $_FILES['fileField']['tmp_name'];
$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$image_ext = strtolower(end(explode('.', $image_name)));
$errors = array();
if (empty($product_name) || empty($product_description) || empty($image_name)) {
$errors[] = "All Fields are required";
} else {
if (strlen($product_name) > 55 || strlen($product_description) > 255) {
$errors[] = "One or more fields contains too many characters";
} else {
if (in_array($image_ext, $allowed_ext) === false) {
$errors[] = 'File type not allowed';
}
if ($image_size > 2097152) {
$errors[] = 'Maximum file size is 2MB';
}
}
}
if (!empty($errors)) {
foreach ($errors as $error) {
echo $error, '<br/>';
}
} else {
create_product($product_name, $product_description, $image_temp, $image_ext);
header("location: product.php?product_id='.$product_id.'");
exit();
}
}
?>
产品.PHP 页面:
<?php
// check to see the url variable product_id is set
if (isset($_GET['product_id'])) {
$product_id = preg_replace('#[^0-9]#i','',$_GET['product_id']);
// use this variable to check to see if this product ID exists...
// if yes then get details...
// if no then exit this script and give error
$sql = mysql_query("SELECT * FROM products WHERE product_id = '$product_id' LIMIT 1");
$productCount = mysql_num_rows($sql); // count the output
if ($productCount > 0) {
// get all the product details
while($row = mysql_fetch_array($sql)) {
$member_id = $row['member_id'];
$timestamp = strftime("%b %d %Y", strtotime($row['timestamp']));
$prodtitle = $row['bmtitle'];
$proddesc = $row['bmdesc'];
}
} else {
echo "That product does not exist";
exit();
}
} else {
echo "Need data - product id needed to render this page is missing.";
exit();
}
?>
然后我在这个product.php页面中继续回显$prodtitle等变量
最后包含的产品功能页面:(仅显示 create_product 功能):
<?php
function create_product($product_name, $product_description, $image_temp, $image_ext) {
$product_name = mysql_real_escape_string(htmlentities($product_name));
$product_description = mysql_real_escape_string(htmlentities($product_description));
mysql_query("INSERT INTO products (product_id, member_id, timestamp, prodtitle, proddesc, image_temp, image_ext) VALUES ('','".$_SESSION['member_id']."', UNIX_TIMESTAMP(), '$product_name', '$product_description', '$image_temp', '$image_ext')");
mkdir('uploads/'.mysql_insert_id(), 0777);
mkdir('uploads/thumbs/'.mysql_insert_id(), 0777);
// place image & thumbnail in the respective folder
$bmid = mysql_insert_id();
$image_file = "$bmid."."jpg";
$location = "uploads/$bmid/$image_file";
move_uploaded_file($_FILES['fileField']['tmp_name'],$location);
create_thumb('uploads/'.$bmid.'/', $image_file, 'uploads/thumbs/'.$bmid.'/');
}
?>
最佳答案
这一行是错误的:
header("location: product.php?product_id='.$product_id.'");
应该看起来像这样:
header("Location: product.php?product_id=$product_id");
请注意没有单引号。
此外,您似乎根本没有在 CREATE_PRODUCT.PHP 中定义 $product_id
