php returning FALSE from private function in another function -

php returning FALSE from private function in another function -

My Codeigniter controller has the following private functions that validates the file upload.

  Personal function Avatar_file_validation () {$ config ['upload_path'] = './uploads/avatars/'; $ Config ['allowed_types'] =' jpg | PNG '; $ Config ['overwrite'] = true; // Overwrite user avatar $ config ['max_size'] = '800'; // $ KB in this- & gt; Load-> Library ('upload', $ config); If (! $ This-> upload-> do_upload ('avatar_upload')) {$ error_data = array ('error' => $ this-> upload-> display_errors ()); $ This- & gt; Avatar_view ($ error_data); // Load View Refund FALSE; }}    If there is an error in uploading then I want to stop this function on  
  function upload_over () {// something Code if ($ _ files) ['Entry_upload'] ['Error']! == 4) // If the file has been added to the field file {$ this- & gt; Avatar_file_validation (); // if return FALSE stop code} // code is released: adds data to the database, redirects}    However the function continues even while returning false. This only works when I use the whole code in 1 function, but I have to separate them because I am using upload verification in multiple functions. What am I doing wrong here?   
 
  expression  return false;  is applicable only for the function  avatar_file_validation () . If you want to stop the code in  upload_avatar () , then when the upload is unsuccessful, you should see the output of  avatar_file_validation ()  and if it is for  FALSE Equal , come back with that function too. For example:  
  function upload_over () {// some code if ($ _ FILES ['entry_upload'] ['error']! == 4) // If the file has been added to the field file (if (! $ This-> avatar_file_validation ()) // Return returns FALSE stop code FALSE;} // Code continues: Adds data to database, redirects}

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.

Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code. Eclipse automatically produces an .apk file in the project's bin folder, so you do not need to do anything extra to generate .apk.
