Create a new database in MySQL
First, you have to create a new database in your MySQL and we will store those binaries in this database. In the example I will use the following structure, in order to build the database, you have to do the following steps:
Access to the MySQL controller
Enter command "CREATE database binary_data;"
Enter the command "use Binary_data;"
Enter command "CREATE TABLE binary_data (ID INT (4) Not NULL auto_increment PRIMARY KEY.
Description char (m), Bin_data longblob, filename char (m), FileSize char (50), filetype char (+));
If there are no surprises, the database and tables should be set up.
An example of how to store files with this example you can transfer files to a database through an HTML form.
Store.php3
The following are the referenced contents:
<?php
store.php3-by Florian Dittmer <dittmer@gmx.net>
?>
<HTML>
<BODY>
<?php
If a form is submitted, the code is executed:
if ($submit) {
Connecting to a database
(You may need to adjust the host name, username and password)
mysql_connect ("localhost", "root", "password");
mysql_select_db ("Binary_data");
$data = Addslashes (Fread (fopen ($form _data, "R"), FileSize ($form _data));
$result =mysql_query ("INSERT into Binary_data (Description,bin_data,filename,filesize,filetype)".
"VALUES (' $form _description ', ' $data ', ' $form _data_name ', ' $form _data_size ', ' $form _data_type ')");
$id = mysql_insert_id ();
Print "<p>this file has the following Database ID: <b> $id </b>";
Mysql_close ();
} else {
Otherwise display the form that stores the new data
?>
<form method= "POST" action= "<?php echo $PHP _self;?>" enctype= "Multipart/form-data" >
File description:<br>
<input type= "text" name= "form_description" size= ">"
<input type= "hidden" name= "max_file_size" value= "1000000" >
<br>file to Upload/store in database:<br>
<input type= "File" Name= "Form_data" size= ">"
<p><input type= "Submit" name= "submit" value= "Submit" >
</form>
<?php
}
?>
