  1. Mr. Professional

    Very Nice Tutorial Sir…

  2. Hi,
    Error :’Network request failed’

    How can i solve this?


  3. Hi, your web is awesome about react native, but i need some tutorial about insert images into mysql with react native and CRUD react native with php mysql, can you help ? thanks

  4. Message show that data enter successfully but not received any data in my online server database

  5. I checked all but not found any problem in that ….can you give me your facebook id for help ?

  6. Thank your for your support the problem solved and your tutorial is very good I hope you provide more material in future also and its request to kindly provide the CRUD video of react native also

  7. Where do I put the DBConfig.php and submit_user_info.php?

    Do I store those files on the server?

    I’m using Xampp, to create and run a MYSQL database. Do you know how I can achieve this?


  8. Great Tutorial. I made some subtle changes because I think of newer versions of React-Native.
    After I run the update I get errors: JSON Parse error: Unexpected identifier “insert” Then a bunch of errors from the core product. I have the submit_user_info.php and the DBConfig on my server.
    How would I debug this. Is it the logon, the SQL query etc.
    I am using Expo XDE and Genymotion to test this.

  9. Everything works fine but i get a response JSON Parse error unrecognized token ‘<' instead of user registered succesfully
    from the server

    • Solex you need to check DBConfig.php file for all server configuration and also check your table name in submit_user_info.php . One more thing you are running php script on localhost or online server.

  10. Yeah the problem was in the submit_user_info.php Everything is perfect now thanks admin looking forward to seeing more tutorials Thanks
