代码：
<!DOCTYPE html >
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Untitled 1</title>
<script src="https://cloud.tinymce.com/stable/tinymce.min.js"></script>
<script>tinymce.init({ selector:'textarea' });</script>
</head>
<body>
<form action="insert_product.php" method="post" enctype="multipart/form-data">
<table>
<tr>
<td>Name</td>
<td><input type="text" name="product_title" required="required"></td>
</tr>
<tr>
<td>category</td>
<td><select name="product_category" >
<option>Select a Category</option>
<?php
$get_cats = " select * from categories";
$run_cats = mysqli_query($con, $get_cats);
while($row_cats = mysqli_fetch_array($run_cats))
{
$cat_id = $row_cats['cat_id'];
$cat_title = $row_cats['cat_data'];
echo "
<option>$cat_title </option>
";
}
?>
</select></td>
</tr>
<tr>
<td>featured</td>
<td><select name="product_featured" >
<option>0</option>
<option>1</option>
</select></td>
</tr>
<tr>
<td>price</td>
<td><input type="text" name="product_price" required="required"></td>
</tr>
<tr>
<td>image</td>
<td><input type="file" name="product_image" required="required"></td>
</tr>
<tr>
<td>keywords</td>
<td><input type="text" name="product_keywords" required="required"></td>
</tr>
<tr>
<td>description</td>
<td><textarea name="product_description" cols="20" rows="10" ></textarea></td>
</tr>
<tr>
<td><input type="submit" value="Add Product" name="insert_post"></td>
</tr>
</table>
</form>
</body>
</html>
<?php
if( isset($_POST['insert_post']))
{
$product_title = $_POST['$product_title'];
$product_category = $_POST['$product_category'];
$product_featured = $_POST['product_featured'];
$product_price = $_POST['$product_price'];
$product_keywords = $_POST['$product_keywords'];
$product_description = $_POST['$product_description'];
$product_image = $_FILES['product_image']['name'];
$product_image_tmp = $_FILES['product_image']['tmp_name'];
echo $insert_product = " insert into products (product_cat, product_featured, product_title, product_price, product_desc,product_image,product_keywords) values ('$product_category','$product_featured','$product_title','$product_price','$product_description','$product_image','$product_keywords','$product_keywords')";
}
?>这是我打印代码时得到的结果 echo ```
insert into products (product_cat, product_featured, product_title, product_price, product_desc,product_image,product_keywords) values ('','1','','','','champagne culture logo men.png','','')
有人能告诉我我做错了什么吗？我反复检查，看看我是否有任何拼写错误或类似的性质，但我似乎不能确定到底是什么我做错了。如果您能提供任何帮助，我们将不胜感激

笔记
如果没有错误，则需要确保输入是否为空，可以使用empty（）属性检查变量/输入是否为空。
