action hooks - print_r ($vars); not working

[MichaelScofield]

Since I upgraded to v4 I can't print this array. Instead of displaying all the values in the array it only displays one number, which is the order number. Here is the code I have:

 

<?php
function create_store($vars) {
print_r ("<pre>");
print_r ($vars);
print_r ("</pre>");
}
add_hook("AfterShoppingCartCheckout",1,"create_store","");
?>

 

Is this a bug or am I doing something wrong?

[MichaelScofield]

Not sure why it wasn't working. It's working now. But one thing is different in v4: if you want to print a value from the array you need to do it like this: print_r ($vars[1]["addons"]);

 

Doing it like in v3.8 - print_r ($vars["addons"]); - won't work

Its something your doing wrong. It has changed slightly from the old way.

If you look at the wiki at the bottom you will see the variables passed to each hook function.

eg...

<?php
function create_store($OrderID, $OrderNumber, $InvoiceID, $Products, $Addons, $Domains) {
echo"<pre>";
print_r($OrderID);
print_r($OrderNumber);
print_r($InvoiceID);
print_r($Products);
print_r($Addons);
print_r($Domains);
echo"</pre>";
}
add_hook("AfterShoppingCartCheckout",1,"create_store","");
?>

when using this, where does the oiutput display?

 

I know this may sound a stupid question, but I am trying to find out what is given in $params for the hook AfterModuleCreate and am using the below:

 

function actionhook_AfterModulecreate($vars) {
# This function runs when a module suspension command completes success
print_r($params);
}

 

Thing is it just doesnt seem to display anything..... do i need to get it to print somewhere, or have it email them?

I would recommend just capturing the output and throwing it into a text file to see whats being outputted, etc.

[ChrisGooding]

Ok,. realised I was using an old way as a method of using the hook, although I think I now am using it correctly, I still dont get any output (that i know of), using the below:

 

<?php 
function show_params_used($params) {
echo"<pre>";
print_r($params);
echo"</pre>";
}
add_hook("actionhook_AfterModuleSuspend",1,"show_params_used","");
?>

[ChrisGooding]

must have posted at the same time, sorry.

 

How would I go about that, I am not the best coder, usually cobbling stuff together?

 

Oh and thanks for the suggestion

[ChrisGooding]

I have put the following together, but for some reason simply uploading the file to the server stops the entire whmcs install working :shock:

 

Surely my code isn't that bad??

 

Heres what I have -

<?php
# This function runs when a module create command completes success$

$outputFile = "moduleparams.txt";
$fh = fopen($outputFile, 'w') or die("can't open file"); 

add_hook("actionhook_AfterModuleSuspend",1,"show_params_used","");

function show_params_used($params) {
fwrite($fh, $params);
fclose($fh);
}
?>

I just have it email me the params:

 

function DoSomething($params) {
$msg = '';
foreach($params as $param) {
	$msg .= $param."\n";
}

mail("jdoe@gmail.com","Hook DoSomething",$msg,"FROM:test@test.com");

}

Actually, I had to replace hookfunctions.php with the one that Matt provided and it fixed this problem.

How do we usually test the hook ? what is the best way to test the hook as I have to work with DB.
