How to upload images into MySQL database using PHP code
I am trying to save images in my database from HTML form. I have written PHP code to accomplish this task. The program is not generating any error message, but also not inserting image data in MySQL database. Kindly check it. Here i am sharing a excerpt from my code.
/*-------------------
IMAGE QUERY
---------------*/
$file =$_FILES['image']['tmp_name'];
if(!isset($file))
{
echo 'Please select an Image';
}
else
{
$image_check = getimagesize($_FILES['image']['tmp_name']);
if($image_check==false)
{
echo 'Not a Valid Image';
}
else
{
$image = file_get_contents ($_FILES['image']['tmp_name']);
$image_name = $_FILES['image']['name'];
if ($image_query = mysql_query ("insert into product_images values (1,'$image_name',$image )"))
{
echo $current_id;
//echo 'Successfull';
}
else
{
echo mysql_error();
}
}
}
/*-----------------
IMAGE QUERY END
---------------------*/
<form action='insert_product.php' method='POST' enctype='multipart/form-data' ></br>
File : <input type='file' name= 'image' >
</form>
Error Message You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
Solution 1:
Firstly, you should check if your image column is BLOB type!
I don't know anything about your SQL table, but if I'll try to make my own as an example.
We got fields id
(int), image
(blob) and image_name
(varchar(64)).
So the code should look like this (assume ID is always '1' and let's use this mysql_query):
$image = addslashes(file_get_contents($_FILES['image']['tmp_name'])); //SQL Injection defence!
$image_name = addslashes($_FILES['image']['name']);
$sql = "INSERT INTO `product_images` (`id`, `image`, `image_name`) VALUES ('1', '{$image}', '{$image_name}')";
if (!mysql_query($sql)) { // Error handling
echo "Something went wrong! :(";
}
You are doing it wrong in many ways. Don't use mysql functions - they are deprecated! Use PDO or MySQLi. You should also think about storing files locations on disk. Using MySQL for storing images is thought to be Bad Idea™. Handling SQL table with big data like images can be problematic.
Also your HTML form is out of standards. It should look like this:
<form action="insert_product.php" method="POST" enctype="multipart/form-data">
<label>File: </label><input type="file" name="image" />
<input type="submit" />
</form>
Sidenote:
When dealing with files and storing them as a BLOB, the data must be escaped using mysql_real_escape_string()
, otherwise it will result in a syntax error.
Solution 2:
Just few more details:
- Add mysql field
`image` blob
- Get data from image
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
- Insert image data into db
$sql = "INSERT INTO `product_images` (`id`, `image`) VALUES ('1', '{$image}')";
- Show image to the web
<img src="data:image/png;base64,'.base64_encode($row['image']).'">
- End
