[英]form submitted data is not uploaded into database
我正在使用phpcode从表单获取数据并将其上传到数据库。 但是数据没有保存在数据库中。这里的“ insert_product.php”是整个代码所在的文件,单击按钮后将表单重定向到同一页面。 有人可以帮忙吗?
<form action="insert_product.php" method="post" enctype="multipart/form-data">
<table align="center" width="795" border="2" bgcolor="#187eae">
<tr align="center">
<td colspan="7"><h2>Insert New Post Here</h2></td>
</tr>
<tr>
<td align="right"><b>Product Title:</b></td>
<td><input type="text" name="product_title" size="60" required/></td>
</tr>
<tr>
<td align="right"><b>Product Category:</b></td>
<td>
<select name="product_cat" >
<option>Select a Category</option>
<option value="1">Laptop</option>
<option value="2">Computer</option>
</select>
</td>
</tr>
<tr>
<td align="right"><b>Product Brand:</b></td>
<td>
<select name="product_brand" >
<option>Select a Brand</option>
<option value="1">LG</option>
<option value="2">Samsung</option>
</select>
</td>
</tr>
<tr>
<td align="right"><b>Product Image:</b></td>
<td><input type="file" name="product_image" /></td>
</tr>
<tr>
<td align="right"><b>Product Price:</b></td>
<td><input type="text" name="product_price" required/></td>
</tr>
<tr>
<td align="right"><b>Product Description:</b></td>
<td><textarea name="product_desc" cols="20" rows="10"></textarea></td>
</tr>
<tr>
<td align="right"><b>Product Keywords:</b></td>
<td><input type="text" name="product_keywords" size="50" required/></td>
</tr>
<tr align="center">
<td colspan="7"><input type="submit" name="insert_post" value="Insert Product Now"/></td>
</tr>
</table>
</form>
</body>
</html>
<?php
if(isset($_POST['insert_post'])){
//getting the text data from the fields
$product_title = $_POST['product_title'];
$product_cat= $_POST['product_cat'];
$product_brand = $_POST['product_brand'];
$product_price = $_POST['product_price'];
$product_desc = $_POST['product_desc'];
$product_keywords = $_POST['product_keywords'];
//getting the image from the field
$product_image = $_FILES['product_image']['name'];
$product_image_tmp = $_FILES['product_image']['tmp_name'];
move_uploaded_file($product_image_tmp,"product_images/$product_image");
$insert_product = "insert into products (product_cat,product_brand,product_title,product_price,product_desc,product_image,product_keywords) values ('$product_cat','$product_brand','$product_title','$product_price','$product_desc','$product_image','$product_keywords')";
$insert_pro = mysqli_query($con, $insert_product);
if($insert_pro){
echo "<script>alert('Product Has been inserted!')</script>";
echo "<script>window.open('index.php?insert_product','_self')</script>";
}
}
?>
如果这是完整的代码,我找不到类似$con = mysqli_connect(...)
显然,您需要在执行任何查询之前连接到数据库
您需要先连接到数据库,如下所示:
$con = mysqli_connect("localhost","my_user","my_password","my_db");
有关数据库连接的更多信息,请参见 。 如果我是您,那么我将首先通过使连接开始工作,然后将数据插入表中开始,并且只有在您掌握了这些知识之后,我才会着手进行上载文件。
