Default Set in calc element

[mk13]

I learned that when we specify a number of the php array, we should set a spacing like [ x ] rather than set [x] in the default set as rule .

Otherwise I wanted to know that ' &&, || ' was needed whether a kind of rule or not.

This is working and Return the value:
if ('{list___element1}' >=0) {return '123t';}

But this does not work , means Does not Return the value :
if ('{list___element1}' >= 0 && '{list___element1}' =< 9) {return '123';}

Should do.
What "doesn't work"?
If your condition fails it's returning nothing, add something like
return 'yyy';

 

[mk13]

this code should return the '123'

But this does not work , means Return nothing of the value :
if ('{placeholder}' >= 0 && '{placeholder}' =< 9) {return '123';}

 

[troester]

&& is working on my site.
What is your "placeholder"?
You can check your "placeholder" with e.g.

$p=(int)'{placeholder}';//if your are testing against integers you should cast to type int
var_dump($p);exit;
if ($p >=0 && $p<=9)
{return '123';} 	
else
{return 'abc';}

naha, the value(birthday element) casting was string(1) "8". So, I think I should change it to integer...

 

[mk13]

I have a certain that '(int)' converts to integer of cast (on var dump). however the due value isn't returned.
Then I have tested on Calc element and Display element, and the result was same thing.(On calc element test, I have cut the method for storing. )

the code is :

$dob = "{db_persons___birthday}";
$dobstamp = strtotime($dob);
$age = date('Y') - date('Y', $dobstamp);
if (date('md') < date('md', $dobstamp)) {
$p=$age;
}
$db = JFactory::getDBO();
$id = '{db_persons___id}';
$query = "UPDATE db_persons SET age = '$age' WHERE id = '$id'";
$db->setQuery($query);
$result = $db->query();

[B]$p=(int)'{db_persons___age}';
if ($p>=0 && $p=<50){return '0-9';}
else[/B]{return 'NG';}

 

[troester]

Ah,
($p>=0 && $p<=50) (not =<)

 

[mk13]

this also does not work:
($p>=0 && $p<=50) (not =<)

These works :
($p<=50 && $p>=0)
($p>=0 && $p<51)

I have gotten read this:
http://php.net/manual/ja/language.operators.precedence.php

 

[troester]

($p>=0 && $p<=50)
should really do

 

[mk13]

yeah, so It was weird, but I do know why...
Manual said to parse from right of line..

 

[mk13]

I found out this more than previous thing. this sounds like complex for me.
non-associative
1. <
2. <=
3. >
4. >=
5. <>

Anyway I am going to get back to http://fabrikar.com/forums/showthread.php?t=26575&page=3
