How to cancel a file upload using an iframe?

HTTP file upload using PHP without libcurl?

• I'm trying to upload a local file to a website of mine, I have a php script waiting to recieve the file, I've been only able to do this using libcurl, particularly this function: function upload($file,$name){ global $portal; $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_VERBOSE, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $h=fopen('curl.txt','a'); curl_setopt($ch,CURLOPT_STDERR,$h); curl_setopt($ch,CURLOPT_VERBOSE,true)… curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)"); curl_setopt($ch, CURLOPT_URL,"recieve.php"); curl_setopt($ch, CURLOPT_POST, true); // same as <input type="file" name="file_box"> $post = array( "uploadedfile"=> "@$file", "fname" => $name ); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); $response = curl_exec($ch); } now I'm trying to do it without libcurl any ideas?

• Answer:

  The elegant answer is PEAR: HTTP_Upload. About the same number of lines of code you are showing, but with heavy boilerplate doing more of the lifting. php is capable, with script, using HTTP file protocol. You must be fully aware of each step required or you let the bad guys come in. In brief, using defaults, $_FILES[ 'userfile' ][ 'error' ]: gives any missed milestones using POST UPLOAD_ERR_OK is 0 UPLOAD_ERR_INI_SIZE is 1 UPLOAD_ERR_FORM_SIZE is 2 <?php if (is_uploaded_file($_FILES['fileOfmine'][… { copy($_FILES['fileOmine']['tmp_name'], "/www/htdocs/uploadFolder/".$_FILES['fil… } else { echo "<p>Potential script abuse attempt detected.</p>"; } ?> then you move it boolean move_uploaded_file( filename, filedesitnation ); Yeah, I know it doesn't make much sense. This is a whole chapter in several of my PHP books. But you only need CURL if you are making the file come over like StarTrek transporter. File > atoms > File. Whereas php script you really should restrict types.
