php inside tpl

[nil2567]

ok,

I'm trying to do this:

 

foreach($a as $b ){

 

$c = $b; // if I do an echo here I have string insede $c

 

}

$d = 'abcde'.$c // if I do echo here I have the same string inside $d

 

$smarty->assign('url',$d);

 

the result I'm geting is just abcde

 

any idea why?

 

pleaseeee

$a is an array ?

 

$c = $b

not $c .= $b or $c += $b ?

[nil2567]

$a is an array.

 

but I discover another problem.

 

the problem is:

 

when i do a scandir I get an array.

 

Ex:

 

$a = scandir($directory);

 

if I now do :

 

$smarty->assign('variable',$a)

 

I don't get nothing in the tpl file and I shoud get array.

 

 

If I do

 

$smarty->assign('variable',$a.'hello');

 

I will get outpu of just hello

could you give the $a value

[nil2567]

a have an string. the name of a file inside directory.

It is strenge, I should have an value.

if I do an echo inside the funcion i have the value of a

to resume, I can't output in tpl the value of a scandir

[coeos.pro]

i think $a is not an array, could you put the code you have who is defined $a

[nil2567]

the code is:

 

global $smarty;

 

$dir = "../modules/folder/upload/images/";

$images = scandir($dir);

$ignore = array('.','..');

foreach($images as $image){

if(!in_array($image,$ignore){

$a = $image

}

}

 

echo $a; // here I have the file

 

 

 

$smarty->assign('image',$a.'aaaa'); I'm just having the aaaa tring

ok i understand... $a is NOT AN ARRAY

[nil2567]

at first I simplifyed the code, now I post the real code.

it is streng, it looks like a bug to me.

1º I'm reading the files from a directorie

2º I'm doing a foreach to get out of the array

3º I'm trying to output.

 

I can see the variable hava a value but when I pass it to the tpl file the value wont appear

[coeos.pro]

foreach($images as $image){
if(!in_array($image,$ignore){
$a = $image
}

 

$a is not an array ...

 

foreach($a as $b ){

$c = $b; // if I do an echo here I have string insede $c

}

$c is empty, normal

[nil2567]

ok, try to do this in a module.

 

$a = scandir('folder/');

 

//than pass it to tpl

 

$smarty->assign('b',$a);

 

it wont pass

[coeos.pro]

put {debug} in your tpl file

[nil2567]

no value in the {debug} window.

It is like a bug to me, because I do echo in the backend of the website and I have a value.

in the frontend I don't have

[nil2567]

I think the scope of scandir() don't let it pass to tpl file

I don't know why
