Server-side checks should always be performed. When browsers don't support the mechanism or the files have their extensions altered this check may fail. Supporting browsers will usually restrict the type of files that can be selected to the ones specified in this attribute.Īuthors shouldn't rely on the accept attribute as a strict method of restraining the user input. It provides the browsers with a hint about what type of files the author expects to receive in this control. The accept attribute takes a comma separated list with any of the following: an Internet media type file extensions (like ".jpg" or ".pdf") the strings "audio/*", "video/*" and "image/*" representing sound, video and image files, respectively. Now we'll implement a single file upload with some restrictions about the file type, using the accept attribute in the file input. Files greater than 2MB won't be uploaded. Note: please choose small files (under 300KB) or the upload time may become considerable. Note that the form has the enctype attribute correctly set up to "multipart/form-data", as needed for file uploads.
In our first example we'll set up a form with a single file input, where you'll be able to test the performance of the control with a real file upload. With this information, the browser may set restrictions about the files a user can pick or provide extended functionalities for specific types of files, like for example, allowing the capture of a picture with the webcam when the allowed types are of images.Īuthors shouldn't rely on the accept attribute as a strict method of restraining the user input. The accept attribute may be used in this element to give a hint to the browser about what types of files the user should be able to submit. When the boolean attribute multiple is present, users may select more than one file to be uploaded to the server. When the form is submitted, the selected files are uploaded to the server, along with their name and type.įor the selected files to be properly uploaded to the server, the value "multipart/form-data" must be present in the form's enctype attribute, or in the formenctype attribute of the button used to submit the form. Check if $uploadOk is set to 0 by an errorĮcho "Sorry, your file was not uploaded.The input element, having the "file" value in its type attribute, represents a control to select a list of one or more files to be uploaded to the server. If($imageFileType != "jpg" & $imageFileType != "png" & $imageFileType != "jpeg"Įcho "Sorry, only JPG, JPEG, PNG & GIF files are allowed."
