image validate before uploading code

[rayzun]

Using a form to upload user input like an image to the filesystem and other text to MySQL, how would I check for and only allowing two image types to upload
jpeg and gif

also Ive heard of checking first several bits of the image to validate it is indeed an image.

Can these steps be coded into my existing form, which is done in PHP using insert to mysql table?

If this can be done, I would like to ask for an example of these steps.

its simple to check what type an uploaded file is. php provides you with the type when its uploaded. if you name your file input 'file', then after the upload you will have the following available: $_FILES['file']['type']. You can run a simple if or switch to check for image/gif image/jpeg etc...
then it is possible to store the image data in mysql if you wish, using a blob field.

http://php.net/manual/en/features.file-upload.php has lots of examples on handling uploads.

Try this simple code I made -- You may just want to get some bits and pieces out of it -- But its very useful 🙂
