 Posted: Fri Jul 29, 2016 4:01 pm Post subject: How find out the value of the next index in foreach/section |
 |
|
Need to know the value of the next Index in the current loop.
my $array is:
| Code: | array[0].amount = 10;
array[1].amount = 20;
array[2].amount = 30; |
| Code: |
{section name=id loop=$array}
var a = {$array[id.index].amount}; // a is 10
var b = {$array[id.index_next].amount}; // not working
{/section}

| that is simply Unbelievable!. I would just have the next "index" of an array. most programming languages its solved by [i + 1], why it is so complicated here? |

How do you know that your indices are numeric and sequential?... The application could pass anything to your template, and your task is to render it, nothing more.
In 99.(9)% of tasks, if you need to know an index in advance, you've not formulated your problem correctly and trying to solve it backwards.
But, if you are dead set on solving it exactly this way, no matter how stupid that is, then http://www.smarty.net/docs/en/language.function.assign.tpl (heed the warning!)
| Code: | {foreach $array as $item}
{if $item@first && $item@last}
{assign "_key" -1}
{assign "_value" null}
{/if}
{if isset($_key)}CurItem: {$item@key} = {$item}
PrevItem: {$_key} = {$_value}{/if}
{assign "_key" $item@key}
{assign "_value" $item}
{/foreach} |

thank you sir for your reply.
I understand your argument, but before I write a complex program I get a "syntax" error. I do not have great experience in "smarty", but looks matter how the array should be able to find the next index.
I tried your code, but I get a blank white page. (Syntax error)
My problem is this:
I have a tiered pricing and depending on how the input, you get a discount.
Standard Price: 12 $ per m
e.g: 10m = $ 10 per m / 20 m = 9 $ / 30 m = 8 $ / ... / 50 m = 6 $
my array of tiered pricing is: "{$Artikel->staffelPreis_arr}"
this has the following structure:
".nAnzahl" For scale quantity (10,20, ..) and
".cBasePriceLocalized[$NettoPreise]" for the Best Offers (10 $ 9 $, ..)
"summeMeter" is the input
"staffelMenge" is the current scale quantity in the loop
"staffelPreis" is actually renders Staffelpreis in the loop
"staffelMengeNext" to represent the next scale quantity
"endPreis" is the new price
Now comes my condition:
| Code: |
{foreach $Artikel->staffelPreis_arr as $differentialPrice key=id}
var staffelMenge = {$differentialPrice.nAnzahl};
var staffelMengeNext = {$Artikel->staffelPreis_arr[id.next_index].nAnzahl}; //doesn't work
var staffelPreis = "{$differentialPrice.cBasePriceLocalized[$NettoPreise]}";
staffelPreis = staffelPreis.replace(',','.');
staffelPreis = parseFloat(staffelPreis).toFixed(2);
if(summeMeter >= staffelMenge && summeMeter < staffelMengeNext){
endPreis = staffelPreis;
return;
}
{/foreach}

yes.
I found the problem but i cant solve it. Its not working because I am writing inside a <script>, I have tested the code outside the <script> and its working. But I need the script for some variables. I tried many solutions for {literal} but not worked.
{foreach $array as $myArray name=arrayName}
{$nextValue=$array[$smarty.foreach.arrayName.index+1].item}
{/foreach}
but I want this inside my <script> |
