Phonegap No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access
ajax, cordova, jquery, json, php
Solution
There should be no cross origin issue in phonegap/cordova as long as you configure properly access origin in config.xml.
It's normal that you have this message when testing from a browser if you miss some CORS headers.Try adding :
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST');
But once again you don't need those headers for a phonegap app.
When you do `echo "hi";`, your're not sending json but sending a text "hi". (just writing json in the header does not format what you echo).
I think you should either use `$.get` in the javascript and remove `header('Content-Type: application/json');` from php so that the app expects a simple text or modify your php to really send JSON.
for ex:
echo "{message:\"hi\"}";
Problem
In phonegap I have an issue while calling a PHP file using jQuery AJAX. The error that occurs while calling the file is: No 'Access-Control-Allow-Origin' header is present on the requested resource Google said to put this code `header('Access-Control-Allow-Origin: *');` in the current PHP file header. I put the code in the header, but still no changes. I've attached my jsfidde with it. The file `connectionsqlphp.php` code is here ``` <?php header('Access-Control-Allow-Origin: *'); header('Content-Type: application/json'); echo "hi"; ?> ```
