Ionic 3 Angular 4 PHP Token Based Restful API User Authentication Login and Signup.

PHP Restful API Authentication Login and Signup using Ionic 3 and Angular 4.

[igor]

For everyone having the JSON error, I'm not sure if this is the correct solution, but I got it without errors by doing this:

1 - go to your index.php in the api folder
2 - check the signup function: function signup()
3 - delete or comment the following 'echo' lines:
echo $email_check.'<br/>'.$email;
echo 'here';
4 - save the index.php
5 - refresh the app and try again

Very good tutorial! Current version of Ionic takes care of importing new providers, so you don't need to import it manually.

Hello tamada and thank you for this series of video.
It really helps me to take Ionic ionic 3. but I have
all encountered some problems. I followed this video
to the letter and the execution was perfect.
But soon after nothing except this console error when I try to login or register

I found a solution for the JSON error saying {error: {text: "Enter valid data"}}
try putting username that is alphanumeric and other attributes in the table are set into VARCHAR in which some inputs must be alphanumeric to be accepted.

hello friend, I find it excellent what you explain here, and thank you for it.
I have a doubt that I would be grateful if you could solve it ...
I noticed that when a name is repeated in the database, an error is generated in the registry ... to which this question arises, as it would notify the user if it has already been registered previously and avoid that error but a message onscreen

bonjour,
je n'arrive pas a faire fonctionner postman, à chaque fois erreur de proxy ou objet introuvable? quel sont les paramètres pour que ça fonctionne? est ce que c'est une étape obligatoire?

merci d'avance.
