Programming
In our development environment, let's suppose that we want to make this
validation in more than one place in this application.
We have the option to create a method using this code in order to avoid
writing the same code more than one time. Let me copy the code down into the
programming
PHP methods -> new method we will call it
"validatefreight" -> create button, all we have to do is paste the code with the
only difference that we have to change the freight
for a local variable and then click on the fire button
to create parameters in this function. Let me
add a parameter, it can be for value or for reference
let's use value save it, and now we can see that we have on top of the method we
are going to have the function validate receiving the local variable
as parameter. All we have to do now is instead of having all that code
we can change it to validate freight receiving the freight as parameter
so when you burn it it will work the same way
"The freight is OK" and "The freight is too high".
Let's suppose now that you want to use this validation in another application
or another project we can create a library with this method
we will copy the code then going to tools libraries
once again we can save it as public, project
or just for the user. This library I will create just for this project
"new" button, then let me paste the code
with the difference that we have to do it as if we were using
only pure PHP we have to add the function "validatefreight"
to receiving the local variable as parameter opening curly brackets
and in the n we can't forget the closing curly brackets
the name can be validate2 then I will save it
only have to do now is back into my Form
into the programming -> library I have to enable the function validate2
and then back into the "onvalidate", let's change the name to
validatefreight2 and run the application
if we try to change the freight to a higher value than a hundred
the Scriptcase will continue to make that validation made by us
and if we change to a value under it it will show us the alert telling that the
freight it's okay
