PHP - else, "escape" nesting and skip to elseif
I wasn't sure what to call this question - Here is a snippet of what I am doing:
<?php
if ($result_rows >= 1 && $membership = 'active') {
if ($when_next_allowed > $today_date) {
$output = 'You cannot renew your membership for another <b>' . $days_left . 'days</b>.';
}
/*
What if the membership is set to active, but it been over a year since they
activated it? We don't have any server-side functions for determining such
at the time.
*/
else {
/* do database stuff to change the database entry to inactive */
/* skip to elseif below */
}
}
elseif (2 == 2) {
/* create new database entry for user membership */
}
?>
If the first nested argument is false , it should jump to else , which should continue from there and "exit" from the parent, if and jump to elseif . Another wise one , if the first nested argument is true , then it should stay put .
Is it even possible? The only thing I could think of would be to add some commands continue;
. This is, of course, a mistake.
Another idea of mine was to set the variable equal to else and then set it right up to the end of the parent if: continue;
if (1 == 1) {
...
else {
$escape = 'continue;';
}
/* $escape here */
}
But I have never heard and do not know any method of using variables in such a "raw" form. Of course, I've been doing research, although I have yet to figure out how to do this. I'm not sure if this is general knowledge or something else. But I never heard of it or thought it until now.
Decision? This is what I have always thought about, although I never knew I would have to use it.

The cleanest I could come up with:
$run = false;
if (1 == 1) {
$run = true;
if (1 == 2) {
/* Do something */
} else {
$run = false;
/* Do something else */
}
}
if (!$run && 2 == 2) {
}
Alternatively, you can use a goto between the [Do Something Else] and the 2nd if block, but that would be messy anyway.
if (1 == 1) {
if (1 == 2) {
/* Do something */
} else {
/* Do something else */
goto 1
}
} else if (!$run && 2 == 2) {
1:
}

If I understand the problem correctly, you can simply do something like this:
if (1==1 && 1==2) {
/* ... */
}
elseif (2==2) {
$success = 'Success';
}
Obviously I don't need to point out which 1==1 && 1==2
is completely illogical and is just being used as an example of two boolean operators.
Update based on update to question:
If there are no additional steps that you omit, this repeats your logic. It's hard to know if this really solves your problem because I don't know what it represents 2==2
, or what other steps you might need to follow based on other conditions.
if (($result_rows >= 1 && $membership == 'active') &&
($when_next_allowed > $today_date)) {
$output = 'You cannot renew your membership for another <b>' . $days_left . 'days</b>.';
}
elseif (2 == 2) {
/* create new database entry for user membership */
}

This should do what you want to do. If you have a variable set to false and switch it to true, if you change to a different location, you just need to check the value of that variable right after you jump to the elseif you would like to enter.
<?php
$test = false;
if (1 == 1) {
if (1 == 2) {
/* ... */
}
else {
/* Skip to elseif below */
$test = true;
}
}
if ($test == true) {
$success = 'Success';
}
echo $success;
?>

Not an easy question as it is difficult to understand what you are trying to achieve, but I think this is the solution you are looking for.
<?php
$success = False;
if (1 == 1) {
if (1 == 2) {
/* ... */
} else {
$success = True;
/* True case code can go here */
}
}
echo $success;
?>
pseudocode is your friend.
As an alternative;
<?php
$success = False;
if (1 == 1) {
if (1 == 2) {
/* ... */
} else {
$success = True;
}
}
if $success == True {
/* ... */
}
echo $success;
?>
