I search about the code for retrieving data from database when the retrieve button was click. But I canít find any codes that similar in my situation.
Here is the flow of my system. I have plt_no and a retrieve button. The retrieve button is to check if the plt_no is already exist or not if it is already exist the data from the database will appear in the text area/textbox and if the plt_no did not exist thereís a message that the id number did not exist and I can input data in the textboxes.
I have an idea of using this code:
This code is to check if the Retrieve button is click and the plt_no is the data which the retrieve depend on. Like for example the user put plt_no 111 and when the user click the Retrieve button, if the 111 is already exist the data will appear in the textboxes but if not thereís a message appear saying the plt no did not exist.
And I have search code for retrieving data:
$plt_no = $_POST['plt_no'];
I attach my full code.
My problem is how can I used that code and if that code is the code I need to used for retrieving data.
I have an idea but i am luck of knowledge in coding
Any help is highly appreciated I ma willing to learn and share
