Warning : Use of undefined constant DOWNLOADTRACKTABLE – assumed ‘DOWNLOADTRACKTABLE’ (this will throw an Error in a future version of PHP) in /home/customer/www/bitrepository.com/public_html/wp-content/plugins/wp-downloadcounter/downloadcounter-config.php on line 23 In this tutorial I will show you how to create an image validator script. Our form will send the data to validate_image_upload.php. Here, the script will check the type of validation. If the file is validated the user will see a successful submission message and the file will be moved in the specified image folder. The uploaded file failed to pass the validation process? In this case, it will be deleted and the script will output an error message. Check the complete validate_image_upload.php file which has the HTML Form and the Validator: validate_image_upload.php Validate Image on Upload @ BitRepository.com ‘; } ?> Select an Image: NOTE Please make sure the config.php file is located in the same folder with validate_image_upload.php, and the folder where the image file will be moved is writable.

Should I use getimagesize( ) to check if a file is valid?
Check if uploaded image is valid with getimagesize( ) in PHP –
| 1 2 3 4 | $imagesizedata = getimagesize ( $file ); if ( $imagesizedata ) |
but PHP docs says not to use getimagesize( ) to check that a given file is a valid image. it’s true that getimagesize( ) returns an array with some random values for image height & width, when the given file is not a valid image.
