Break Parent IF (Conditional) - php

Question

How can i break parent if in PHP?
example this code:
if(true){ // This is parent conditional
if(true) { // This is child conditional
break parent conditinal
}
}
afterBreakDoMe();
From code above. I want when child conditional is true. Then it break parent conditional (exit from that conditional) and continue the rest of the code (afterBreakDoMe()).
Update - Real code
$errorMessage = '';
if(isset($_POST) && count($_POST)) { // Detect some user input
// validation
$countryName = trim($_POST['countryName']);
if($countryName == ''){ // validation user input, if false. exit from parent if and continue show html input (refer to $Render->output())
$errorMessage = 'Name must not be empty!';
}
header('Location: '.$baseUrl.'&page=tableShipping');
}
$Render->setTitle('Create New Country');
$form = $Render->parser('createCountry', array(
'errorMessage' => $errorMessage,
));
$Render->addContent($form);
$Render->output();

Answer 1

You cannot do that (except using goto, which is taboo), and should not do that. Swapping functionality for simplicity is a bad idea.
Based on your "real" code, your program flow doesn't make sense.
if($countryName == ''){ // validation user input, if false. exit from parent if and continue show html input (refer to $Render->output())
So, if it's true, you're going to set $errorMessage, then exit, leave the page, and never use it again? Why? You might as well just forget the error message, call the header(), then call exit;.
I've created the following code based on what I think you want to happen, and commented it as an explanation:
$errorMessage = '';
if(isset($_POST) && count($_POST)) { // Detect some user input
// validation
$countryName = trim($_POST['countryName']);
if($countryName == ''){ // validation user input, if false. exit from parent if and continue show html input (refer to $Render->output())
$errorMessage = 'Name must not be empty!';
} else {
// If there is no error, continue forward.
header('Location: '.$baseUrl.'&page=tableShipping');
exit; // Leave the page execution since you've applied a header.
}
}
// This will only execute if there is an error, since we left the page otherwise.
$Render->setTitle('Create New Country');
$form = $Render->parser('createCountry', array(
'errorMessage' => $errorMessage,
));
$Render->addContent($form);
$Render->output();
All in all, consider the flow of your program in order to determine what happens next, not what to skip.

You could use a variable and an extra if-statement:
$errorMessage = '';
$emptyCountry = false;
if(isset($_POST) && count($_POST)) { // Detect some user input
// validation
$emptyCountry = trim($_POST['countryName']) == '';
if($emptyCountry){ // validation user input, if false.
$errorMessage = 'Name must not be empty!';
}
header('Location: '.$baseUrl.'&page=tableShipping');
}
if (!emptyCountry) {
$Render->setTitle('Create New Country');
$form = $Render->parser('createCountry', array(
'errorMessage' => $errorMessage,
));
$Render->addContent($form);
}
$Render->output();

Answer 3

Simple
if (true) {
if (true) {
// Do stuff
// It will then break automaticly
// but if the condition here is false you got the else ;)
} else {
}
}

Answer 4

Use goto. This is used for jumping in code

Answer 5

Now that I can read the real code sample I think what you need to do is simple put all the conditionals together in a single. Using goto will get the job done but can easily make you code hard to read and maintain. Perhaps its time to rethink the program flow.
Anyway, what I am saying is something like this:
if(!empty($_POST) && isset($_POST['countryName']) && (trim($_POST['countryName']) == '')){
$errorMessage = 'Name must not be empty!';
}
...

Answer 6

$errorMessage = '';
do {
if(isset($_POST) && count($_POST)) { // Detect some user input
// validation
$countryName = trim($_POST['countryName']);
if($countryName == ''){ // validation user input, if false. exit from parent if and continue show html input (refer to $Render->output())
$errorMessage = 'Name must not be empty!';
break;
}
header('Location: '.$baseUrl.'&page=tableShipping');
}
while(false);// only for break
