PHP is a high level server side programming language. To upload an image file first you need to update the php.ini file. Open the php.ini file. Search “file_uploads”. Update the line “file_uploads = On”.
Then to upload the file you need to Create HTML. Look at the example below. Here I have a input type=”file” control & a submit button. Both these controls are inside the form element. With form I am using post method to send my image files to the server. Finally after successful uploading showing File Name, Size & Type to the user using a UL li element.
To restrict user on file type to upload I created an array “expensions”. Here you can declare any specific file type you want to allow the user. In this example I allowed “jpeg”,”jpg”,”png”.
During file upload to track the errors I am with one more array “errorlog”. In case of a failure I am displaying the error details using echo function.
Script for PHP upload image
<?php
if(isset($_FILES['uploader'])){
$errorlog = array();
$fileSize = $_FILES['uploader']['size'];
$fileType = $_FILES['uploader']['type'];
$fileTemp = $_FILES['uploader']['tmp_name'];
$fileName = $_FILES['uploader']['name'];
$fileExtension = strtolower(end(explode('.',$_FILES['uploader']['name'])));
$expensions= array("jpeg","jpg","png");
if(in_array($fileExtension,$expensions)=== false){
$errorlog[] = "This file type is not allowed, Select a JPEG or PNG file.";
}
if($fileSize > 2097152){
$errorlog[] = 'Your file size is more than 2 MB. Upload a file less then 2 MB.';
}
if(empty($errors)==true){
move_uploaded_file($fileTemp,"images/".$fileName);
echo "Successfully Uploaded.";
}
else {
print_r($errorlog);
}
}
?>
