Two Coding Questions

1. Where is the appropriate place in the cart, to set the php error_reporting variable to "E_NOTICE"?

2. What does "$db->Execute()" actually return, and what can I put in my foreach loop to cycle through each row?

EG:

PHP Code:


foreach($db->Execute() AS $row)

{

   echo $row['name'];

   echo $row['ID'];

}

Hi,

There are a couple of ways of getting extended error reporting .

First Way.

Create a file in includes/local/ called configure.php with the following code

PHP Code:


<?php

define('STRICT_ERROR_REPORTING', true);

This will set error reporting to E_ALL

or create a file in includes/extra_configures/

called something like custom_error.php

with the following code

PHP Code:


<?php

@ini_set('display_errors', '1');

error_reporting(E_ALL);

this ini_set is in case all error reporting is disabled in your php.ini file.

You can of course change E_ALL to whatever you want.

As for the db question.

$db->execute() returns a result set object .

To iterate over the result set you should do

PHP Code:


$result = $db->execute('sql query');

while (!$result->EOF)

{

//actual query result are in the $result->fields[]  array  

$result->moveNext();

}

Thanks Wilt,

It would be cool if there were a "developer's manual" or similar, that explained all the objects, variables, and the program flow...

One more question: I need to load a javascript object with the <body onload="" > option. It looks like there's a hook in place called "$zv_onload" that does this, but where/how do you set it's value?

I need the script to load on the "product_info" page.

Thanks again,

Nick

Look into index.php for the logic on how your custom Javascript can be loaded automatically by Zen Cart into the <body onload=""> section of a page. The "$zv_onload" variable is set there.

For a page-specific Javascript to appear on the the Product Info page's onload() section, place your custom Javascript file into the product info page that matches the particular product type.

Your custom Javascript file must have the following syntax:

on_load_xxx.js

where "xxx" is the custom name you give the file.

Based on your example. Let's say your product matches the product type Product-General and your custom Javascript file is on_load_yourfilename.js.

For your custom Javascript to load on the particular Product Info page, your custom Javascript file should appear as follows:

/includes/modules/pages/product_info/on_load_yourfilename.js

PS: For more information on other default Javascript loading possibilities, look in the following file:

/includes/templates/template_default/common/html_header.php

Cool, Thanks guys!

Is there anyway to call a side box anywhere in the page? I saw the "sideboxes anywhere" contribution, but that seems to apply to the entir site, not whithin Zen Cart itself. I'd like to put something like:

Code:

<?php // require(DIR_WS_MODULES . 'sideboxes/categories.php'); ?>

In the header, but I'm having varying degrees of success. It *sort of* works if I use:

Code:

<?php //require(DIR_WS_MODULES . zen_get_module_directory('column_right.php')); ?>

first, but this causes problems for obvious reasons...
