    Hello,

    How can I declare acceptable file types using MIME types.is there any hook have? I have tried with contact form 7 hooks but it’s not worked. can you please check it we need to solve this issue ASAP.

    example:

    add_filter('wpcf7_validate_file*', 'cf7_custom_file_validation', 10, 2);
add_filter('wpcf7_validate_file', 'cf7_custom_file_validation', 10, 2);

function cf7_custom_file_validation ($result, $tag) {
    if ($tag->name === 'file-123') {
        $contentType = mime_content_type($_FILES[$tag->name]['tmp_name']);

        if ($contentType !== 'application/docx' && $contentType !== 'application/pdf' && $contentType !== 'application/doc'&& $contentType !== 'application/rtf') {
            $result->invalidate($tag, 'This file type is not supported');
        }
    }

    return $result;
}

    Thanks

    Hello @navasahmed ,

    You could try this filter.

    add_filter( 'wpcf7_validate_mfile',  'cf7_custom_file_validation', 10, 2 );
add_filter( 'wpcf7_validate_mfile*',  'cf7_custom_file_validation', 10, 2 );

function cf7_custom_file_validation ($result, $tag) {
    if ($tag->name === 'file-123') {
        $files =  $_POST[ $tag->name ][0]; // this could be an array
        $type = wp_check_filetype( $files );
        $contentType = $type['type'];
        if ($contentType !== 'application/docx' && $contentType !== 'application/pdf' && $contentType !== 'application/doc'&& $contentType !== 'application/rtf') {
            $result->invalidate($tag, 'This file type is not supported');
        }
    }

    return $result;
}

    Hello @navasahmed ,

    Can you print_r the $files & $type and send me the screenshot of the result?

    Thanks.

    Hello @glenwpcoder,

    Another issue I am facing is that the mandatory filed error does not appear after the drag and drop field https://snipboard.io/LtpY2j.jpg.

    Also, I’ve tried printing $files & $type but the form keeps loading.

    Thanks

    Maybe the print_r caused the error not to show the validation message.

    Just remove the print_r.

    Also, I tried your code in my local and it’s working correctly see here – https://snipboard.io/NozK3x.jpg

    Hello @glenwpcoder,

    Did you try adding a drag-and-drop field at the end of the form? If so, please add the field between any other fields, like https://snipboard.io/BjAOMQ.jpg. Afterwards, add this code and check the validation for the Drag and Drop field and also for the fields after that.

    Thanks

    Hello,

    Any updates on the above query? the issue is still on the site. we can upload renamed files. here I will breaf down my question.

    if game.exe is renamed as game.pdf and uploaded then it needs to be blocked. currently, it’s not blocking.

    I have checked your shared code and it’s only checking the wp_check_filetype() I think it only gives the file extension, not checking the file mime type. can you please check it the issue.

    also please check your mail. i have contacted through there also.

    Thanks

    Thanks, I received your email.

    I’m currently updating so I can release a new version that includes mime type validation.

    My apology for the delay, expect an update within this week.
