UPDATED: As suggested in comment section I have updated my code and using PDO now. I still have the same error.
I am trying to store multiple images to the database (phpmyadmin). When I try to upload it gives an error Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'file.png' in 'field list'
My database:
I have an database named image_upload and inside it has a table named car_detailss which has an id (int11), car_name(varchar 255) and imageOfcar(longblob).
That’s my image details:
Array
(
[0] => Array
(
[name] => file.png
[type] => image/png
[tmp_name] => /opt/lampp/temp/phpJYyrQn
[error] => 0
[size] => 77776
)
[1] => Array
(
[name] => files.png
[type] => image/png
[tmp_name] => /opt/lampp/temp/phpXOLvzL
[error] => 0
[size] => 84710
)
)
As suggested in comment section I am using PDO now That’s my code: (UPDATED)

$file_count = count($file_post['name']);
$file_keys = array_keys($file_post);
for ($i = 0; $i < $file_count; $i++){
foreach($file_keys as $key) {
$file_ary[$i][$key] = $file_post[$key][$i];
}
}
return $file_ary;
}
function pre_r($array) {

print_r($array);

How can I fix the error it displays (at the top) I mentioned?

Answer
As suggested in the comment section. I first changed my code to PDO and instead of inserting into database without any backticks or “”, I followed the suggestion in comment section and added backticks and “” while inserting the images into database.
$conn->exec( "INSERT INTO car_detailss (car_name, imageOfcar) VALUES ('$carname', '$imagename')");
Now I am able to insert the images to my database. I have updated my code here as well.
My code:
<!doctype html>
<html>
<head>
<title>Test</title>
</head>
<body>
<form method="post" enctype="multipart/form-data">
<input type="file" name="userfile[]" multiple="" />
<input type="submit" name="submit" value="upload" />
</form>
<?php
$servername="localhost";
$username="root";
$password = "";
$dbname="image_upload";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname",$username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// begin the transaction
$conn->beginTransaction();
$phpFileUploadErrors = array(
0 => "There is no error, the file uploaded with success",
1 => "The uploaded file exceeds the upload_max_filesize directive in php.ini",
2 => "The upload file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form",
3 => "The upload file was only partially uploaded",
4 => "No file was uploaded",
6 => "Missing a temporary folder",
7 => "Failed to write file to disk.",
8 => "A php extension stopped the file upload"
);
if(isset($_FILES['userfile'])) {
$file_array = reArrayFiles($_FILES['userfile']);
pre_r($file_array);
for($i=0;$i<count($file_array);$i++) {
$carname = $file_array[$i]["size"];
$tablename = "car_detailss";
$imagename = $file_array[$i]["name"];
$conn->exec( "INSERT INTO `car_detailss` (`car_name`, `imageOfcar`) VALUES ('$carname', '$imagename')");
}
}
$conn->commit();
echo "new records created succesfully";
} catch(PDOException $e) {
// roll back the transaction if something failed
$conn->rollback();
echo "Error: " . $e->getMessage();
}
$conn = null;
function reArrayFiles($file_post) {
$file_ary = array();
$file_count = count($file_post['name']);
$file_keys = array_keys($file_post);
for ($i = 0; $i < $file_count; $i++){
foreach($file_keys as $key) {
$file_ary[$i][$key] = $file_post[$key][$i];
}
}
return $file_ary;
}
function pre_r($array) {
echo '<pre>';
print_r($array);
echo '</pre>';
}
