Then try the Get String Value block with Do It
“Do it” is a block of which component?
I tested like this, and it was empty
I think you will get an array after parsing response content.
I need to learn how to get values returned from the database to be used in the app. See I made another screen in less than 15 minutes, where I look for the amount of students present and absent in the classroom, but I’m not able to manipulate this return.
I want to put the returned values (in the example below) on their labels.
I really didn’t understand what the ParseJson method does with the parameter passed to it. Does it do something and return or save this change where?
Actually I am not very good in Parsing JSON or using JSON.
Can you send me response content?
Then I can answer your question.
This topic should help you regarding JSON:
With these same returns (in another app), I manipulate using the Add Items To List loop + Look Up in Pairs key and save it to a list and this list show it in a LISTVIEW. But in this specific case, I just need to take the value and use it in the app.
If it is saved as list then use select list item block.
Please post here Response content as text in reply.
It’s that…
[{“CNOMEFUNC”:“RAFAEL PEIXOTO PEREIRA”},{“cnomemat”:“MODULO PRATICO”}]
I put Response Content on this Json parser … it looks all ok.
Here too all ok
First parse array one by one and then get desired value.
Hint:- use loops to make it easy
But it gives me this error:
Parse error on line 1: [{“CNOMEFUNC”:“RAFAEL --^ Expecting 'STRING', '}', got 'undefined'
Dear , is Very stranger. Expecting String ? The word “RAFAEL” is in quotes and the return comes PHP function json_encode that is the same function I use in the others app.
Opinion: version 3 of the extension seems easier to use
Tested the json_last_error () PHP function to check for JSON errors and returned the JSON_ERROR_NONE constant.
The problem is that in the JSON text, the quotes you used are these ones “”, not the regular "". That’s why JSON is not valid and hence is not parsed.
Also, I suggest using our own JSON component in Utilities category.

Friend, I just passed this JSON string because the other friend asked. I do not use this wrong quote. I know that the JSON interpreter gave an error message because the quotes were wrong, but the quotes that are returned by the PHP function are the right ones. I use this function in other apps and return correct quotes.This string is the return of the function. Look at the picture.
