Zencart has a great override system. I’m currently setting up a Zen Cart website and loving this override system. The only improvement I see that is REALLY NEEDED is an ADMIN OVERRIDE. That would be terrific. Until then here’s a schematic of the current Zen Cart override system.

Anybody else update from 1.3.8 to 1.3.9 and you cannot log into the admin anymore. Just an infinite loop of typing your password over and over again to end up back at the login screen with the username and password boxes cleared. When you type the password incorrect, it lets you know, but when it’s correct you’re stuck in an infinite loop of trying to log in over and over again.

Here’s what we do to fix this problem.

Zen cart’s forums and wiki are great, just somewhat of a pain in the ass, so here’s what i found that is useful, and i may use in the future too.

Re: Overriding functions/html_output.php
There is no in-built override system for files in the includes/functions folder, but I recentyly figured out a method to do it by utilizing the override capabilities within the autoload/init_includes system.

First, make a copy of includes/init_includes/init_general_functions.php and save it in the includes/init_includes/overrides/ folder. Then edit that file to modify the loading of the html_output.php file so that it calls the file from an overrides folder like:
Code:
require(DIR_WS_FUNCTIONS . ‘overrides/html_output.php’);
Then you can create your new folder includes/functions/overrides/, and put an edited copy of html_output in there. This way you can edit or add functions within html_output.php and not have to worry about duplicate functions warnings, or about your changes getting overwritten during an upgrade.

You can use a similar method for overriding anything in the functions or classes folders, which don’t have an inherent override capability.

Here’s how I moved my Zen Cart installation to a sub directory.

1.) Create a sub directory on your site via: FTP or however you know to.

2.) Move all files of your Zen-Cart installation into your sub directory.

3.) Edit 2 configuration files of your zen-cart.

• /includes/configure.php
• /admin/includes/configure.php

In /includes/configure.php you want to edit:

• DIR_WS_CATALOG
• DIR_WS_HTTPS_CATALOG
• DIR_FS_CATALOG
• DIR_FS_SQL_CACHE

In /admin/includes/configure.php you want to edit:

• DIR_WS_ADMIN
• DIR_WS_CATALOG
• DIR_WS_HTTPS_ADMIN
• DIR_WS_HTTPS_CATALOG
• DIR_FS_ADMIN
• DIR_FS_CATALOG

In both of these files you simply want to add your <subdirectory> followed by a forward slash /

NOTE: All directories should not have a leading slash / and SHOULD ALL have a trailing /
example:

define(‘HTTP_SERVER’, ‘http://192.168.1.1/’);

define(‘HTTP_SERVER’, ‘http://www.example.com/’);

define(‘DIR_WS_ADMIN’, ‘shopping-cart/admin/’);

4.) Now you need to access your database via: phpMyAdmin or NaviCat

In your Zen Cart database you want to edit the configuration table in the following fields:

• Log Destination – STORE_PAGE_PARSE_TIME_LOG
• Session Directory – SESSION_WRITE_DIRECTORY

Use the following utility if you don’t know how to do step4:

http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=82

This worked great for me.
Please comment here if you try this or have any questions.
Thank you.

Posted from Diigo. The rest of my favorite links are here.

I Remade this diagram so i can read it on an 8×11 printer. Enjoy

Diagram of Product flow in the ZenCart Database

Making basic actions in the admin interface of magento here’s 5 queries that are executed, just 5 of more than 50 queries.

What I’m trying to accomlish is adding a roller over effect to the images.  I want the image to pop up in another layer on rollover.

As always, with any editing of any files that currently already work, make a BACKUP!

I like to copy and paste the file, then rename it .backup

First I add the code to the css file:

skin/frontend/default/default/css/boxes.css

.product-image {
position: relative;
width: 100px;
height: 180px;
}

.product-image a .large {
border: 0px;
display: block;
height: 1px;
left: -1px;
position: absolute;
top: -1px;
width: 1px;
}

.product-image a img {
border: 0;
}

.product-image a.p1, .product-image a.p1:visited {
background: #FFFFFF;
border: 0px solid #000000;
display: block;
height: 100px;
left: 0;
text-decoration: none;
top: 0;
width: 100px;
}

.product-image a.p1:hover {
background-color: #8C97A3;
color: #000000;
text-decoration: none;
}

.product-image a.p1:hover .large {
border: 1px solid #000000;
display: block;
height: 320px;
left: 0px;
position: absolute;
top: 0px;
width: 480px;
z-index:50;
}

Then I want to edit my template file:

app/design/frontend/default/default/template/catalog/product/list.phtml

Find the line (about line 100-105) that contains:

<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>">
 <img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(170, 170); ?>" alt="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" />

add the php signs around that and comment it out, then add my following lines:

<?php

//STEVEN KOHLMEYER PICTURE POPUP

$_fm_a = $_product->getProductUrl();
$_fm_b = $this->htmlEscape($this->getImageLabel($_product, 'small_image'));
$_fm_c = $this->helper('catalog/image')->init($_product, 'small_image')->resize(170, 170);
$_fm_d = $this->htmlEscape($this->getImageLabel($_product, 'small_image'));
$_fm_e = $this->htmlEscape($this->getImageLabel($_product, 'small_image'));
$_fm_c_2 = str_replace("small_image/170x170", "image", $_fm_c);

echo '<a href="'.$_fm_a.'" title="'.$_fm_b.'">
';
echo '<img src="'.$_fm_c.'" alt="'.$_fm_d.'" title="'.$_fm_e.'" />
';
echo '<img src="'.$_fm_c_2.'" alt="'.$_fm_d.'" title="'.$_fm_e.'" />
';
 /*

 <a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>">
 <img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(170, 170); ?>" alt="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" />
 */
 ?>

The image resize function all depends on how you have manento setup and the cache, but this should work.  Feel free leave comments on how this works.

Searching low and high, trying every search string i can think of in google. I’ve found nothing. Posting on Magento Commerce’s website i got a response with the answer. Here is the answer:

The file you are looking for is: Mage/Catalog/Block/Product/List/Toolbar.php

In this file at line 530 function getAvailableLimit()

public function getAvailableLimit()
{
if ($this->getCurrentMode() == 'list') {
if (isset($this->_availableLimit['list'])) {
return $this->_availableLimit['list'];
}
$perPageValues = (string)Mage::getStoreConfig('catalog/frontend/list_per_page_values');
$perPageValues = explode(',', $perPageValues);
$perPageValues = array_combine($perPageValues, $perPageValues);
return ($perPageValues /*+ array('all'=>$this->__('All'))*/);
}
elseif ($this->getCurrentMode() == 'grid') {
if (isset($this->_availableLimit['grid'])) {
return $this->_availableLimit['grid'];
}
$perPageValues = (string)Mage::getStoreConfig('catalog/frontend/grid_per_page_values');
$perPageValues = explode(',', $perPageValues);
$perPageValues = array_combine($perPageValues, $perPageValues);
return ($perPageValues /*+ array('all'=>$this->__('All'))*/);
}
return parent::getAvailableLimit();
}


as you can see the

return ($perPageValues /*+ array('all'=>$this->__('All'))*/);

I comment /*+ array(’all’=>$this->__(’All’))*/
now the “All” show anymore ….

Or course you should not change the core but sometime it’s easier then build an override
for it.

You should test it on a development store before !!!!
USE AT YOUR OWN RISK !!!!

Let me know if you have any problem

Error: Please check for sufficient write file permissions

Your Magento folder does not have sufficient write permissions, which this web based downloader requires.

If you wish to proceed downloading Magento packages online, please set all Magento folders to have writable permission for the web server user (example: apache) and press the “Refresh” button to try again.
Refresh

To learn more about setting write permissions, please visit the Magento community site for further details.

Ever seen the above error message?  I have.  Solution’s I’ve found for this are as follows:

I installed magento through SSH as root.  Now the problem with this is all the folders magento creates is now owned by root, so apache or magento cannot change them.  Simple fix.  From what I read off of MagnetoCommerce.com is somebody changed the owner of the downloader folder.   I tried this, it didn’t fix my problem.  Feel free to try this way though.
chown apache downloader/ -hR

I took this a step further since I was still having the same problem.  I did this to the entire website directory

chwon apache www/ -hR

Let me know if this works for you.
