How to INSERT an array of uploaded filenames into a table and later display them?

I am working on a project where each item could have multiple images, I created a form that would accept the images and store them into an array. The problem is whenever I try inserting the images into a table row in the database it displays an error:
"Array to string conversion"
How can I fix this? And also how do I fetch each images on another page from the same database table. Below is my code.
-Form code

$img_name_new = $_FILES['imgs']['name'] is an array of one or more image names.
You will need to decide how you wish to store the array data as a string in your database.
Here are a couple of sensible options, but choosing the best one will be determined by how you are going to using this data once it is in the database.
implode() it -- $img_name_new = implode(',', $_FILES['imgs']['name']);
json_encode() it -- $img_name_new = json_encode($_FILES['imgs']['name']);
And here is my good deed for the year...

file_get_contents(): Filename cannot be empty (uploading files to be optional)

I am new to php. I made a simple upload form in php. This is my code.
<html><head></head>
<body>
<form method="post" action="" enctype="multipart/form-data">
Upload File:
<input type="file" name="upload" /><br>
<input type="submit" name="submit" value="Submit"/>
</form>
</body>
</html>
<?php
include("config.php");
if(isset($_POST['submit']) )
{
$filename = $con->real_escape_string($_FILES['upload']['name']);
$filedata= $con->real_escape_string(file_get_contents($_FILES['upload']['tmp_name']));
$filetype = $con->real_escape_string($_FILES['upload']['type']);
$filesize = intval($_FILES['upload']['size']);
if ($_FILES['upload']['name'] == 0 ){
echo "<br><br> New record created successfully";
}
else {
$query = "INSERT INTO contracts(`filename`,`filedata`, `filetype`,`filesize`) VALUES ('$filename','$filedata','$filetype','$filesize')" ;
if ($con->query($query) === TRUE) {
echo "<br><br> New record created successfully";
} else {
echo "Error:<br>" . $con->error;
}
}
$con->close();
}
?>
It works fine. But if I press the submit with no files attached, it displays the error, Warning: file_get_contents(): Filename cannot be empty in C:\xampp\htdocs\contractdb\filetest.php on line 20 .
I want uploading files to be optional because not every user has the files to attach. I also want the user to download the files after uploading without removing file_get_contents($_FILES['upload']['tmp_name']).
How do I do this?
Your check should take in place before calling file_get_content() so it does not throw an error and you only call the function if file input is not empty:
if(isset($_POST['submit']) ) {
if ($_FILES['upload']['size'] != 0 ) {
$filename = $con->real_escape_string($_FILES['upload']['name']);
$filedata= $con->real_escape_string(file_get_contents($_FILES['upload']
['tmp_name']));
$filetype = $con->real_escape_string($_FILES['upload']['type']);
$filesize = intval($_FILES['upload']['size']);
$query = "INSERT INTO contracts(`filename`,`filedata`, `filetype`,`filesize`) VALUES ('$filename','$filedata','$filetype','$filesize')" ;
if ($con->query($query) == TRUE) {
echo "<br><br> New record created successfully";
} else {
echo "Error:<br>" . $con->error;
}
}
else {
echo 'error: empty file';
}
}
Try this:
if (isset($_POST['submit']) & ($_FILES['upload']['name']!=''))
{
// Statement
}

PHP/MYSQL: Importing csv files through php into a mysql table

I have been trying this code I found from this site here: https://www.johnboyproductions.com/blog/tutorial-import-a-csv-file-using-php-and-mysql
It works perfectly for me locally, but when I try the code on a live site. It says that the data is imported but does not reflect in the database. I am adding the code below:
if ($_FILES[csv][size] > 0) {
//get the csv file
$file = $_FILES[csv][tmp_name];
$handle = fopen($file,"r");
//loop through the csv file and insert into database
do {
if ($data[0]) {
mysqli_query("INSERT INTO tablename VALUES
(
'".addslashes($data[0])."',
'".addslashes($data[1])."'
)
");
}
} while ($data = fgetcsv($handle,1000,",","'"));
//
//redirect
header('Location: filename.php?success=1'); die;
}
That's the functionality part, I will post the form section below:
<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1">
Choose your file: <br />
<input name="csv" type="file" id="csv" />
<input type="submit" name="Submit" value="Submit" />
</form>
Any help will be greatly appreciated. Thanks
I have tried another code that was used initially which is working now:
if(isset($_POST['Submit']))
{
if ($_FILES['csv']['size'] > 0)
{
//get the csv file
$file = $_FILES['csv']['tmp_name'];
$handle = fopen($file,"r");
$firstRow = true;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
if($firstRow) { $firstRow = false; }
else {
$str="INSERT INTO tablename VALUES
('' ,
'".addslashes($data[0])."',
'".addslashes($data[1])."'
) ";
$result = mysqli_query($connection,$str);
if($result)
$cnt++;
}
}
fclose($handle);
//redirect
// header('Location: filename.php?success=1'); die;
}
}

How to upload image and save path to database?

I have a page where some images are shown (database driven). Here is the code of my gallery.php :
<ul id="portfolio-list" class="gallery">
<?php
$sql="select * from eikones ";
$res=mysql_query($sql);
$count=mysql_num_rows($res);
for ( $i = 0; $i < $count; ++$i )
{
$row = mysql_fetch_array( $res );
$co=$i+1;
if(isset($row[ "path" ]))
{
$path= $row[ "path" ];
}
if(isset($row[ "auxon" ]))
{
$auxon = $row[ "auxon" ];
}
if($_SESSION['role'] == "admin")
echo "<li class=\"pink\"><img src=\"$path\" alt=\"Pic\"></li>\n";
}
?>
</ul>
Now I want to have a form where I will be able to upload an image. I am trying this but it doesn't work :
<form enctype="multipart/form-data" action="gallery.php" method="post" name="changer">
<input name="image" accept="image/jpeg" type="file">
<input value="Submit" type="submit">
</form>
<?php
include 'conf.php'; //database connect
if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) {
$tmpName = $_FILES['image']['tmp_name'];
$fp = fopen($tmpName, 'r');
$data = fread($fp, filesize($tmpName));
$data = addslashes($data);
fclose($fp);
$query = "INSERT INTO eikones"; //table name = "eikones" and it has two columns named "auxon" and "path". The auxon is the id.
$query .= "(image) VALUES ('','$data')";
$results = mysql_query($query, $link) or die(mysql_error());
print "DONE";
}
else {
print "NO IMAGE SELECTED";
}
?>
It says "NO IMAGE SELECTED" and nothing new comes into the database.
After some hours I found a solution. It works. Although I would still be happy to find a second solution (according to the code I first posted here). Here is the second solution :
form page :
<form enctype="multipart/form-data" action="insert_image.php" method="post" name="changer">
<input name="image" accept="image/jpeg" type="file">
<input value="Submit" type="submit">
</form>
insert to database page :
<?php
include 'conf.php';
if ($_FILES["image"]["error"] > 0)
{
echo "<font size = '5'><font color=\"#e31919\">Error: NO CHOSEN FILE <br />";
echo"<p><font size = '5'><font color=\"#e31919\">INSERT TO DATABASE FAILED";
}
else
{
move_uploaded_file($_FILES["image"]["tmp_name"],"images/" . $_FILES["image"]["name"]);
echo"<font size = '5'><font color=\"#0CF44A\">SAVED<br>";
$file="images/".$_FILES["image"]["name"];
$sql="INSERT INTO eikones (auxon, path) VALUES ('','$file')";
if (!mysql_query($sql))
{
die('Error: ' . mysql_error());
}
echo "<font size = '5'><font color=\"#0CF44A\">SAVED TO DATABASE";
}
mysql_close();
?>
There are plenty of small classes you can download to handle your image uploads. Here's something small I just coded up. It will allow you to set validation for file type and file size. Feel free to make some methods private or hardcode the protected variables in the constructor if you know they'll always be the same. It may need a little work, but you can either use this class or pull out the bits you need to do it procedurally. Forgive any minor errors.
class ImageUploader{
protected
$size_limit,
$allowed_extensions;
$failed_saves;
public function __construct(int $limit, array $extensions){
$this->size_limit = $limit;
$allowed_extensions = $extensions;
}
public function saveImage(array $images){
foreach($images as $image){
if($this->meetsSizeLimit($image['size'])){
if($this->hasValidExtension(end(explode(".", $image["name"])))){
$this->storeImage($image, $this->getNextImageIndex());
}
else $failed_saves[$image["name"] = "Invalid file type.";
}
else $failed_saves["name"] = "File is too large.";
}
return $failed_saves;
}
public function meetsSizeLimit(int $size){
return $size <= $this->size_limit;
}
public function hasValidExtension(string $extention){
return in_array($extension, $this->allowed_extensions)
}
public function storeImage($image, $unique_id){
move_uploaded_file($image["tmp_name"], "you_relative_file_path" . $image["name"]);
rename('your_relative_file_path' . $image["name"], 'your_relative_file_path/img' . $unique_id . '.' . $extension);
//Place your query for storing the image id and path in table 'eikones'
}
public function getNextImageIndex(){
//Code to get the next available image id or MAX(id) from table 'eikones'
}
}
