FuelPHP makes it easy to implement social login by using a package called Opauth. #Create Facebook app This isn’t limited to FuelPHP, but in order to implement social login with Facebook, you must first create a Facebook app for social login on Facebook.

Comments should be concise and accurate so that they are easy to read and understand. I understand that, but if I wrote it in all the processing The entire source becomes hard to read. Comments also need to be organized. Unnecessary comments and necessary comments It is better not to write in the comments what you can see. // Determine if you are human if ($ object-> isHuman () === true) { // Make the name Taro $ name ='tarou'; } When you can clearly understand the contents of processing with the help of method names and variable names, I don’t think you need to bother to comment. https://sourcetut.com/control-the-transition-destination-at-the-time-of-error-with-laravel-validation-43584/ Wed, 09 Sep 2020 00:00:00 +0000 https://sourcetut.com/control-the-transition-destination-at-the-time-of-error-with-laravel-validation-43584/ Problem -When an error occurs in the validation of Laravel, it does not return to the page at the time of input. -When returning to the page at the time of input when an error occurs in the validation of Laravel, the value is not retained.

I recently had the opportunity to work on a project to upgrade Laravel from var5.2 to var6, and I’ve summarized the experience I gained there, albeit roughly. I hope it will be helpful for those who are planning to upgrade from now on! In addition, it was a version upgrade in an environment where the implementation of the test code is not so much, but if you are writing the test code properly, it is recommended to check it by turning the test! https://sourcetut.com/get-update-items-with-key-value-in-laravel-and-dynamically-validate-and-update-7a921/ Wed, 09 Sep 2020 00:00:00 +0000 https://sourcetut.com/get-update-items-with-key-value-in-laravel-and-dynamically-validate-and-update-7a921/ TL; DR When developing API, usually get the update item by FormRequest and execute validation. However, if you want to send only the items to be updated as a request and only one item, this is not the case with normal implementation. Therefore, I will try to implement it in a slightly tricky ~~ redundant ~~ way. Environment -PHP7.4 -Laravel7.2 Implementation of normal update processing Normally, you send a request for update processing as follows. https://sourcetut.com/install-phalcon-devtools-mac-aec4b/ Wed, 09 Sep 2020 00:00:00 +0000 https://sourcetut.com/install-phalcon-devtools-mac-aec4b/ Last time, I created a Phalcon development environment with vagrant, but I also needed to use Phalcon Devtools, so There are some differences from the document, so make a note of the error resolution process. composer global require phalcon / devtools Then I got an error: Problem 1 --phalcon / devtools v4.0.3 requires ext-phalcon ^ 4.0.0-> the requested PHP extension phalcon is missing from your system. --phalcon / devtools v4. https://sourcetut.com/laravel8-a-memo-that-i-immediately-tried-the-new-login-jetstream-607ea/ Wed, 09 Sep 2020 00:00:00 +0000 https://sourcetut.com/laravel8-a-memo-that-i-immediately-tried-the-new-login-jetstream-607ea/ Laravel8: A memo that immediately tried the new login “jetstream” Hello everyone I’m Yamazaki, Chief Lecturer of G’s Academy m (_ _) m This time, I will update to Laravel 8 and do My Memo for creating Login screen.

In PHP, if you put a character string in a variable, the variable will be a string type, and if you put an integer, it will be an int type.

To achieve this, the Like function uses JavaScript instead of the form tag as the method of communicating from the client (PC or smartphone browser) to the server (Laravel side).
