I'm just trying to make a real simple Survey via php. Just want it to
play the Question Files, wait for a response, save the response into the
correct variable and then email it all.
I have no issue playing the audio or emailing. But I can't get it to
wait for digits or to properly capture those digits into the variables.
I know the code is technically right since the emails have this in place
of what Q1 should be "200 result=35 endpos=2400" instead of whatever
digit I pressed during testing.
Anyway my questions are
A. How to have it play the whole audio file before it goes to the
next command, without having to use the sleep function preferably.
B. How to make it actually wait for digits
C. How to get it to actually capture the digits (I think it would
if it wasn't streaming thru the whole file without waiting for a
response.)
I'm just trying to capture digits 1-9 nothing fancy.
#!/usr/bin/php -q
<?php
// Get AGI vars from *
$agivars = array();
while (!feof(STDIN)) {
$agivar = trim(fgets(STDIN));
if ($agivar === '') {
break;
}
$agivar = explode(':', $agivar);
$agivars[$agivar[0]] = trim($agivar[1]);
}
extract($agivars);
// Variable Declarations
$agi_uniqueid;
$agi_callerid;
$agi_calleridname;
$agi_extension;
$agi_uniqueid;
$UNIQUEID = $agi_uniqueid;
$CALLERID = $agi_callerid;
$CallerName = $agi_calleridname;
$EXTEN = $agi_extension;
$Q1 = "Did Not Answer";
$Q2 = "Did Not Answer";
$Q3 = "Did Not Answer";
$Q4 = "Did Not Answer";
$Q5 = "Did Not Answer";
// Q1
fwrite(STDOUT, "STREAM FILE /var/lib/asterisk/sounds/1 ###\n");
fwrite(STDOUT, "wait for digit 10\n");
$Q1 = fgets(STDIN);
// This section is where the email would be generated, but since that
section works. No point making this any longer than need be.

Just my .02. In my asterisk (1.4.21.2 using Polycom phones), The read in
AGI doesn't work as expected. This is a simple thing to do in a dialplan
and pass to php for the "lifting".
Here's what I would do:
exten => s,1(readq1),Read(digitq1,record/q1,16,skip,1,10])
exten => s,n,Gotoif($["${LEN(${digitacc})}" <
"1"]?readq1)
exten => s,n,AGI(checkdigit.php|${digitq1})
Not the answer you want and I'm sure someone will give you the correct
answer if I'm wrong.

See your code snippet below.> A. How to have it play the whole audio file before it goes to the next > command, without having to use the sleep function preferably.Use "stream file" with the appropriate escape digits.> B. How to make it actually wait for digitsUse "wait for digits" with the appropriate timeout. Accumulate digits for the desired effect.> C. How to get it to actually capture the digits (I think it would if it > wasn't streaming thru the whole file without waiting for a response.)An alternative is to use the background, playback, and read dialplan applications from your AGI.> // Q1 > fwrite(STDOUT, "STREAM FILE /var/lib/asterisk/sounds/1 ###\n"); > fwrite(STDOUT, "wait for digit 10\n");You don't understand the AGI protocol. For every request (the bit you send to Asterisk) you need to read the response (the bit Asterisk sends to you). Issuing 2 requests breaks the protocol. Please use an established library to handle all the little details of AGI for you. You will live longer :) Using an established library will take care of all these seemingly insignificant details and save you a lot of time.

My write up is here (http://www.theopensourcerer.com/2009/04/16/asterisk-agi-programming-with-packt/) if you are interested, it might be a big help depending on your time-scales etc. Al PS - Disclaimer: Packt sent me this book for free and under no obligation.
