php upload file path to mysql - php

Question

So, I am creating a very simply uploader where I take in a file/name/description and to store to store the file to the server and name/desc/filepath.
This is what my database looks like:
Basically, i take in a file, name, and description and want the file to be stored in the server. While the path/name/desc to be stored into mySQL. I also want an incrementing ID. I have a db named "test". And want to post to "test_table". The database is already created but I need to check if the table exists, if not, create it. I think I have the basics of mySQL correct below, but I need to know how to check for table/create if needed and how to set the path variable. Thanks in advance!
Also, how do I increment the ID variable in mysql with each entry? does that happen automatically or .. ?

Answer 1

you need to upload your file to the server before inserting in the database:
if ($_FILES['fileinput']['name']!="") {
if (is_uploaded_file($_FILES['fileinput']["tmp_name"])) {
$name = date("Y-m-d : H:i:s")." ".$_FILES['fileinput']['name'];
$filevalue = $nameoffile;
$path =$file_save_path.$nameoffile;
if (move_uploaded_file($_FILES["file".$i]["tmp_name"], $uploaddir.$nameoffile)) {
$sql = "INSERT INTO test_table (name, desc, path) VALUES ($name, $desc, $path)";
mysqli_query($conn, $sql)
} else {
echo "File Upload Error. Please Try again";
}
}
}

To check, if a table exists, see this question: check if MySQL table exists or not
Essentially, this is the code to check:
if(mysql_num_rows(mysql_query("SHOW TABLES LIKE '".$table."'"))==1)
echo "Table exists";
else echo "Table does not exist";
To autoinc the ID just use the autoincrement attribute to the ID field, see the documentation here for more info: https://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html
Code:
ALTER TABLE test_tabel MODIFY COLUMN ID INT auto_increment
Hope this helps...
