The file uploader on the HTML page only allows for PNG files to be uploaded

Currently, I am working on an application where I am facing a challenge related to file uploads. Specifically, I have an input field like this:

<input id="full_demo" type="hidden" name="test[image]">

I am looking for a way to restrict the upload of only .jpg files. Is there any method or technique available that can help me achieve this?

In my code, changing the input type from "hidden" to "file" poses an issue with the cropper plugin not functioning as expected.

Although I attempted the following code snippet, it did not work as intended:

<input type="file" name="pic1" accept="image/jpeg" />

Answer №1

It is actually jpeg, not jpg.

<input type="file" name="picture1" accept="image/jpeg" />

Answer №2

If you're looking to upload images, consider using the following code snippets.

<input type="file" name="pic1" id="image" accept="image/jpeg" />

To allow for multiple image formats, use this code instead.

<input type="file" name="pic1" id="image" accept="image/gif, image/jpeg, image/png" />

Answer №3

<input type="file" name="myImage" accept="image/x-png, image/gif, image/jpeg" />

Keep in mind that the accepted file types specified in the input tag are just a suggestion to the browser on which files to display to the user. It's important to validate the uploaded file on the server as well to ensure security.

This feature is supported in IE 10+, Chrome, Firefox, Safari 6+, Opera 15+, but there may be limited support on mobile devices (as of 2015). Some reports suggest that this feature may prevent certain mobile browsers from uploading files at all, so thorough testing on different platforms is recommended.
