Upload and Validate an Image in PHP

In this tutorial I will explain how to upload a image and how to validate image extension

Create a HTML form with two text field :

One is for Image title with input type text.
Second one is for upload image with input type file.For file upload input must be file(type=”file”). This input type show the file select control.

HTML form must have following attributes :

method=”post”
enctype=”multipart/form-data” (The enctype attribute specifies how the form-data should be encoded when submitting it to the server.)

without these attributes , the image upload will not work.

<form name="uploadimage"  enctype="multipart/form-data" method="post">
<table width="100%"  border="0">
<tr>
<th width="26%" height="60" scope="row">Image Title:</th>
<td width="74%"><input type="text" name="imagetitle"  autocomplete="off" class="form-control" required /></td>
</tr>
 
<tr>
<th height="60" scope="row">Upload Image :</th>
<td><input type="file" name="image"  required /></td>
</tr>
 
<tr>
<th height="60" scope="row">&nbsp;</th>
<td><input type="submit" value="Submit" name="submit" class="btn-primary" /></td>
</tr>
</table>
</form>

<tr>

<th width="26%" height="60" scope="row">Image Title:</th>

</tr>

<tr>

<th height="60" scope="row">Upload Image :</th>

</tr>

<tr>

</tr>

</table>

</form>

Create a database with name imagesdata. Inside this database we create a table with name tblimages.

SQL Script for tblimages

CREATE TABLE IF NOT EXISTS `tblimages` (
  `id` int(11) NOT NULL,
  `ImagesTitle` varchar(120) DEFAULT NULL,
  `Image` varchar(150) DEFAULT NULL,
  `PostingDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;

CREATE TABLE IF NOT EXISTS `tblimages` (

`id` int(11) NOT NULL,

`ImagesTitle` varchar(120) DEFAULT NULL,

`Image` varchar(150) DEFAULT NULL,

`PostingDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP

) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;

Now create a database connection file(config.php)

<?php
define('DB_SERVER','localhost');
define('DB_USER','root');
define('DB_PASS' ,'');
define('DB_NAME', 'imagesdata');
$con = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);
// Check connection
if (mysqli_connect_errno())
{
 echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

<?php

define('DB_SERVER','localhost');

define('DB_USER','root');

define('DB_PASS' ,'');

define('DB_NAME', 'imagesdata');

$con = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);

// Check connection

if (mysqli_connect_errno())

{

echo "Failed to connect to MySQL: " . mysqli_connect_error();

}

PHP Script for getting posted values, image validation, move images into directory and insertion data into database

ALTER TABLE `tblusers`
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

CREATE TABLE `tblusers` (

`id` int(11) NOT NULL,

Good advice. I still see people not validating file types, which can, of course, have security implications.
