Common mistakes commited in saving image path to a MySQL table - php

Question

I am working on a php project. In one of the webpage I want to keep file upload option for users.
Here is my user input form
<?php
$db=mysqli_connect('localhost','test','test123','study')
?>
<form form action="" method="post" enctype="multipart/form-data">
<label for="file_array[0]">Photo :</label>
<input type="file" name="file_array[0]" accept=".jpeg" required />
<input type="file" name="file_array[1]" accept=".jpeg" required />
<label for="file_array[0]">ID Proof :</label>
<input type="submit" value="Upload All">
</form>
<?php
if(isset($_FILES['file_array'])){
$name_array = $_FILES['file_array']['name'];
$tmp_name_array = $_FILES['file_array']['tmp_name'];
$type_array = $_FILES['file_array']['type'];
$size_array = $_FILES['file_array']['size'];
$error_array = $_FILES['file_array']['error'];
for($i = 0; $i < count($tmp_name_array); $i++){
$v1=rand(1111,9999);
$v2=rand(1111,9999);
$v3=$v1.$v2;
$v3=md5($v3);
$upload_directory="uploads/";
$TargetPath=$v3.$name_array[$i];
if(move_uploaded_file($tmp_name_array[$i],
$upload_directory.$TargetPath))
{
$sql = "INSERT INTO customers (imagepath)
VALUES ("$upload_directory.$TargetPath")";
echo $name_array[$i]." upload is complete<br>";
}
else {
echo "failed to ".$name_array[$i]."
<br>";
}
}
}
?>
the problem is, Image gets successfully uploaded to the directory, but image path is not being saved into the database.
Any suggestion where I'm doing wrong in my code.

Answer 1

In the above code your not executing the query. It is just saved in $sql. refer below code:
if ($db->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $db->error;
}
saving imagepath in db it also depends on the datatype as well.it will be text to save any length of data.
