<foreach> Loop not working

Post by vikas »

Hi

In my code I need to iterate through an Array for which I am using <foreach> tag but this doesn't seem to be working.
Not sure what I am missing.

I have verified that the array is not empty still the call doesn't enter the foreach loop.
I have pasted a section of my code below.

The only line that I see for <foreach> in log is pasted below. The code continues executing skipping <foreach> tag each time.

Code: Select all

<if cond="debug">
				<log expr="'**** sayTransactions Start - Index = '+index + ' Transactions Length = ' +transactions.length  " />
				<log expr="'**** sayTransactions Start - subArray length ' +subArray.length  " />
			</if>
<foreach item="tran" array="subArray">
				<if cond="debug">
					<log expr="'**** In inner foreach - amount '+index+' ' +tran.amount" />
					<log expr="'**** In inner foreach - date '+index+' '+tran.date" />
					<log expr="'**** In inner foreach - date substring '+index+' '+tr
Log::
LOCAL: **** sayTransactions Start - Index = 0 Transactions Length = 6
LOCAL: **** sayTransactions Start - subArray length 5
VXI::foreach_element()

Hi Vikas,

The fact that you see: VXI::foreach_element() in your logs indicates that the foreach loop is being executed, however why those log elements aren't showing up is not immediately obvious. Have you tried removing the if statement from within your foreach loop to see if that makes any difference? Syntactically though, your script looks correct. Could you send us a copy of your array such that we can try and reproduce the issue with the same data?

Regards,
Plum Support

Yes, I tried removing <if> condition; it still doesn't work.
I am sending the code - there are 3 parts
1) VXML code
2) Javascript which creates the array
3) The input to Javascript (<xml> data from an API)

VXML code

Code: Select all

<block name="sayTransactions" cond="index < transactions.length">
			<assign name="subArray" expr="transactions[index]"/>
			
			<if cond="debug">

				<log expr="'**** sayTransactions Start - subArray length ' + subArray.length  " />
			</if>
			
			<if cond="index == 0">

Javascript which creates the array

Code: Select all

Re: <foreach> Loop not working

Hi Vikas,

We used your parse javascript function and xml data to produce a portion of the array structure, which we used to make a simple script to test this issue. However, we do see each log tag being executed within the foreach loop. We tested with the below script:

Code: Select all

<?xml version="1.0"?>
<vxml version="2.1">
  <form>
  <script>
    var transactions = [
      [
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      ],
      [
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      {amount:"10",date:"2016-08-01T18:00:00Z",day:"Monday",description:"Value Load",type:"CREDIT"},
      ],
    ];
  </script>
  <var name="debug" expr="true"/>
  <var name="index" expr="0"/>
  <block name="sayTransactions" cond="index < transactions.length">
     <assign name="subArray" expr="transactions[index]"/>
     
     <if cond="debug">
        <log expr="'**** sayTransactions Start - Index = '+index + ' Transactions Length = ' +transactions.length  " />
        <log expr="'**** sayTransactions Start - subArray length ' + subArray.length  " />
     </if>
     
     <foreach item="tran" array="subArray">
        <if cond="debug">
           <log expr="'**** In inner foreach - amount'+index+' '+tran.amount" />
           <log expr="'**** In inner foreach - date ' +index+' '+tran.date" />
           <log expr="'**** In inner foreach - day '  +index+' '+tran.day" />
           <log expr="'**** In inner foreach - type ' +index+' '+tran.type" />
           <log expr="'**** In inner foreach - desc ' +index+' '+tran.description" />               
        </if>
      </foreach>
     
     <if cond="debug">
        <log expr="'**** sayTransactions End - Index = '+index + ' Transactions Length = ' +transactions.length  "/>
     </if>
     
     <assign name="index" expr="index + 1"/>
     <log expr="'**** sayTransactions End - After Incrementing Index = '+index + ' Transactions Length = ' +transactions.length  "/>
     <if cond="index==transactions.length">
        <if cond="debug">
           <log expr="'**** sayTransactions End - No More Transactions'"/>
        </if>
        <!-- Resetting the value to 9 when there are no more transactions to be read --> 
        <assign name="check" expr="9"/>
        <goto nextitem="checkstep"/>
     <else/>
        <if cond="debug">
           <log expr="'**** sayTransactions End - More Transactions Available'"/>
        </if>
        <goto nextitem="check"/>
     </if>
    </block>
  </form>
</vxml>
and we see the following in the call logs:

Code: Select all

Entering form = '$_internalName_1578520' form item = 'sayTransactions'
VXI::assign_element(name="subArray" expr = "transactions[index]")
LOCAL: **** sayTransactions Start - Index = 0 Transactions Length = 2
LOCAL: **** sayTransactions Start - subArray length 4
VXI::foreach_element()
LOCAL: **** In inner foreach - amount0 10

LOCAL: **** In inner foreach - day 0 Monday
LOCAL: **** In inner foreach - type 0 CREDIT
LOCAL: **** In inner foreach - desc 0 Value Load
LOCAL: **** sayTransactions End - Index = 0 Transactions Length = 2
VXI::assign_element(name="index" expr = "index + 1")
LOCAL: **** sayTransactions End - After Incrementing Index = 1 Transactions Length = 2
LOCAL: **** sayTransactions End - More Transactions Available
Since this is a closed script without any external parsing or data input, we're inclined to believe the reason your foreach is not executing might have to do with external factors, parsing, format of the transactions array, etc. If you could provide more details we'd be happy to help, but it does not appear to be the foreach code itself that's causing the issues.

Re: <foreach> Loop not working

Post by vikas »

It works if I use the "transactions" array provided by you so that means there is something wrong with the input data which is causing <foreach> to skip. However it is still not clear what is wrong with the Array data.

In the same code I have added below debug statements.
Now I can see that the "subArray" element has data still <foreach> is not getting executed.

Do you see anything wrong with the Array content that could cause <foreach> to not execute?

Code: Select all

<block name="sayTransactions" cond="index < transactions.length">
			<assign name="subArray" expr="transactions[index]"/>
			
			<if cond="debug">
				<assign name="subArray" expr="transactions[0]"/>
			
				<log expr="'**** sayTransactions Start - Index = '+index + ' Transactions Length = ' +transactions.length  " />
				<log expr="'**** sayTransactions Start - subArray length ' + subArray.length  " />
				<log expr="'**** Display 1st subArray:: ' + transactions[0]" />
				<log expr="'**** 1st subArray 1st Element:: ' + subArray[0]" />
				<log expr="'**** 1st subArray 2nd Element:: ' + subArray[1]" />
				<log expr="'**** 1st subArray 3rd Element:: ' + subArray[1]" />
				<log expr="'**** 1st subArray 4th Element:: ' + subArray[3]" />
				<log expr="'**** 1st subArray 5th Element:: ' + subArray[4]" />
				<log expr="'**** 1st subArray 1st Element contents:: ' + subArray[0].amount + ',' + subArray[0].date + ',' + subArray[0].day + ',' + subArray[0].type + ',' + subArray[0].description" />
				<log expr="'**** 1st subArray 2nd Element contents:: ' + subArray[1].amount + ',' + subArray[1].date + ',' + subArray[1].day + ',' + subArray[1].type + ',' + subArray[1].description" />
				<log expr="'**** 1st subArray 3rd Element contents:: ' + subArray[2].amount + ',' + subArray[2].date + ',' + subArray[2].day + ',' + subArray[2].type + ',' + subArray[2].description" />
				<log expr="'**** 1st subArray 4th Element contents:: ' + subArray[3].amount + ',' + subArray[3].date + ',' + subArray[3].day + ',' + subArray[3].type + ',' + subArray[3].description" />
				<log expr="'**** 1st subArray 5th Element contents:: ' + subArray[4].amount + ',' + subArray[4].date + ',' + subArray[4].day + ',' + subArray[4].type + ',' + subArray[4].description" />
			
				<assign name="subArray" expr="transactions[1]"/>
			
				<log expr="'**** Display 2nd subArray:: ' + transactions[1]" />
				<log expr="'**** 2nd subArray 1st Element:: ' + subArray[0]" />

				<log expr="'**** 2nd subArray 2nd Element contents:: ' + subArray[1].amount + ',' + subArray[1].date + ',' + subArray[1].day + ',' + subArray[1].type + ',' + subArray[1].description" />
				<log expr="'**** 2nd subArray 3rd Element contents:: ' + subArray[2].amount + ',' + subArray[2].date + ',' + subArray[2].day + ',' + subArray[2].type + ',' + subArray[2].description" />
				<log expr="'**** 2nd subArray 4th Element contents:: ' + subArray[3].amount + ',' + subArray[3].date + ',' + subArray[3].day + ',' + subArray[3].type + ',' + subArray[3].description" />

			</if>
			
			<if cond="index == 0">
				<prompt  cond="isCultureEnUS(language, locale)"> <audio expr="Prompt18"> <speak xml:lang="en-US"> <voice name="Jennifer">  	<value expr="Verbiage18"/>  </voice> </speak> </audio> </prompt>

				<prompt  cond="isCultureFrCa(language, locale)"> <audio expr="Prompt18"> <speak xml:lang="fr-CA"> <voice name="Julie">  	<value expr="Verbiage18"/>  </voice> </speak> </audio> </prompt>					    				
			</if>
			
			<foreach item="tran" array="subArray">
				<if cond="debug">
					<log expr="'**** In inner foreach - amount'+index+' '+tran.amount" />
					<log expr="'**** In inner foreach - date ' +index+' '+tran.date" />
					<log expr="'**** In inner foreach - day '  +index+' '+tran.day" />
					<log expr="'**** In inner foreach - type ' +index+' '+tran.type" />
In the logs below you can see that the subArray does has 5 elements and each element has the required fields namely amount, date,day,type & description. Therefore I am still confused why call is not entering the <foreach> loop

Code: Select all

Entering form = 'getTransactions' form item = '$_internalName_3810005'
LOCAL: *****In Get Transactions*****
Entering form = 'getTransactions' form item = '$_internalName_3810006'
LOCAL: **** #transactions 6
Entering form = 'getTransactions' form item = 'sayTransactions'
VXI::assign_element(name="subArray" expr = "transactions[index]")
VXI::assign_element(name="subArray" expr = "transactions[0]")
LOCAL: **** sayTransactions Start - Index = 0 Transactions Length = 6
LOCAL: **** sayTransactions Start - subArray length 5
LOCAL: **** Display 1st subArray:: [object Object],[object Object],[object Object],[object Object],[object Object]
LOCAL: **** 1st subArray 1st Element:: [object Object]

Re: <foreach> Loop not working

Post by vikas »

I was able to fix it finally by removing below section of code from my Javascript which was creating Array

Code: Select all

var trxDate = new Date(str_date);
		var days_en = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
		var days_es = ["doh-MEEN-goh","LOOH-nayss","MAHR-tayss","mee-AIR-coh-layss","WHAY-vayss","vee-AIR-nayss","SAH-bah-doh"];
		var days_fr = ["dee-MAHNSH","luhn-DEE","mahr-DEE","mehr-kruh-DEE","juh-DEE","vahn-druh-DEE","sahm-DEE"];
		if (locale.toLowerCase()=='es')
		{
			day = days_es[trxDate.getDay()];
			if (type=='CREDIT')
				type = CRÉDITO;
			else
				type = DÉBITO;
		}
		else if (locale.toLowerCase()=='fr')
		{
			day = days_fr[trxDate.getDay()];
			if (type=='CREDIT')
				type = CRÉDIT;
			else
				type = DÉBIT;
		}
		else
			day = days_en[trxDate.getDay()];
