Working on contact from 7

Contact Form 7 implements its own MIME Type check, so it does not support that directly.
This plugin controls the MIME Type check when uploading to WordPress media. If Contact form 7 uses to check MIME Type of WordPress core system for uploading to media, it will affect you, and if not, it will not affect you.

Thanks for your reply.

I have one doubt. if you can help please help me. am using this code for validating the mime. but when am trying the code. the file path can’t readable in WordPress. in core file it’s working.

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-234') {        
 $filepath =$_FILES['file-234']['tmp_name']; // var_dump(mime_content_type($filepath));             
$contentType = mime_content_type($_FILES['file-234']['tmp_name']);        
 if ($contentType !== 'application/pdf') 
{             
$result->invalidate($tag, 'This file type is not supported');        
 }   
}    
 return $result; }

Mime Type Check for Contact Form 7

plugin, and here you can see that
includes/class-cf7-mime-type-check-actions.php
function cf7_custom_file_validation ($result, $tag)

in includes/class-cf7-mime-type-check-actions-actions- php.
I think it is a good idea to use this as a reference.
