Having problem accessing the array

[habbardone]

Hi,
I am trying to get my array working, but I must
have made a mistake somewhere 🙁

the two arrays are :

		
$langs_engl =	array( 
  "engl"=>'English',
  "span1"=>'Spanish: European',
  "span2"=>'Spanish: Latin Am',
  "fren"=>'French',
   "ital"=>'Italian',
  "port1"=>'Portuguese: European',
  "port2"=>'Portuguese: Brazilian',
  "turk"=>'Turkish',
  "punj"=>'Punjabi',
  "n"=>'none'
  );

$langs_span =	array( 
  "engl"=>'iglis',
  "span1"=>'Epanish: European',
  "span2"=>'Epanish: Latin Am',
  "fren"=>'Frensa',
  "ital"=>'Italian',
  "port1"=>'Portuguese: European',
  "port2"=>'Portuguese: Brazilian',
  "turk"=>'Turkish',
  "punj"=>'Punjabi',
  "n"=>'none'
   );

And my test code:

$langs_arr='langs_'.$D_web_cd;

echo "langs_arr: $langs_arr <br>"; 
 echo "D_lang1_cd: $D_lang1_cd <br>";
 echo "$langs_arr[$D_lang1_cd] <br>"; 

when the form makes $D_web_cd = engl

I get this display:

D_web_cd: engl
langs_arr: langs_engl
D_lang1_cd: span1
l

AND
when the form makes $D_web_cd = span

I get this display:

D_web_cd: span
langs_arr: langs_span
D_lang1_cd: span1
l

I should be getting "Spanish: European" in the first
and

I should be getting "Epanish: European" in the second

Can you see what I have done wrong ?

Thanks

While you can do this with variables-variables, I don't recommend it.

If the language choice is mutually-exclusive, you can only select and display entries from one language at a time, the easiest way of doing this is to have each language array in its own file and just require the correct file that matches the current language setting. The name of the array would be the same in all cases, for example - $langs. You would reference entries to match your example using - $langs[$D_lang1_cd].

If you need the ability to display entries from more than one language at a time, you would use a two-dimensional array, where the first index is the language selection -

<?php
$langs = array();
$langs['engl'] =    array(  

  "engl"=>'English', 
  "span1"=>'Spanish: European', 
  "span2"=>'Spanish: Latin Am', 
  "fren"=>'French', 
   "ital"=>'Italian', 
  "port1"=>'Portuguese: European', 
  "port2"=>'Portuguese: Brazilian', 
  "turk"=>'Turkish', 
  "punj"=>'Punjabi', 
  "n"=>'none' 
  ); 

$langs['span'] =    array(  

  "engl"=>'iglis', 
  "span1"=>'Epanish: European', 
  "span2"=>'Epanish: Latin Am', 
  "fren"=>'Frensa', 
  "ital"=>'Italian', 
  "port1"=>'Portuguese: European', 
  "port2"=>'Portuguese: Brazilian', 
  "turk"=>'Turkish', 
  "punj"=>'Punjabi', 
  "n"=>'none' 
   );


// example usage -   

$D_web_cd = 'engl';
$D_lang1_cd = 'span1';

echo "{$langs[$D_web_cd][$D_lang1_cd]} <br>";


$D_web_cd = 'span';
$D_lang1_cd = 'span1';

echo "{$langs[$D_web_cd][$D_lang1_cd]} <br>";

Thanks, I will try that.

Any idea why the "l" appears in the array element ?

[Weedpacket]

You have something else outputting it?

[pbismad]

The 'l' being output is the first character of the $langs_arr string - $langs_arr='langs_'.$D_web_cd; . It's being output by the last echo statement. The $langs_arr string is a numerically indexed array of characters. The $D_lang1_cd value that's being used as an index in the last echo statement is a string as well. When that's converted to a number, it results in a zero and the last echo statement is evaluated as - .echo "$langs_arr[0] <br>";

Edit: well this interesting, when trying to post the above using a quick reply, upon submit it's empty and goes to the full editor with the 'The message you have entered is too short. Please lengthen your message to at least 2 characters.' at the top.

Thanks, for your replies.
Was very helpful in sorting out the problem 🙂
