Problem

The introduction of new payment method "PayPal (new API)" is causing "Credit Card" payment option to appear for no reason.

Solution

To completely get rid of this problem, there are 3 files involved

• administrator/components/com_virtuemart/classes/ps_checkout.php -> method list_payment_methods()
• administrator/components/com_virtuemart/classes/ps_payment_method.php -> method list_payment_radio()
• components/com_virtuemart/themes/default/templates/checkout/get_payment_method_paypal_ex.tpl.php

administrator/components/com_virtuemart/classes/ps_checkout.php around line 830

Paypal (new API) are implemented separately from generic Virtuemart payment methods. So we need to prevent it from reloading again

function list_payment_methods( $payment_method_id=0 ) {
...

$db_nocc  = new ps_DB;
$q = "SELECT * from #__{vm}_payment_method,#__{vm}_shopper_group WHERE ";
$q .= "#__{vm}_payment_method.shopper_group_id=#__{vm}_shopper_group.shopper_group_id ";
$q .= "AND (#__{vm}_payment_method.shopper_group_id='".$auth['shopper_group_id']."' ";
$q .= "OR #__{vm}_shopper_group.default='1') ";
$q .= "AND (enable_processor='B' OR enable_processor='N' OR enable_processor='P' AND `payment_class`!='ps_paypal_api') ";
$q .= "AND payment_enabled='Y' ";
$q .= "AND #__{vm}_payment_method.vendor_id='$ps_vendor_id' ";
$q .= " ORDER BY list_order";
...

}

administrator/components/com_virtuemart/classes/ps_payment_method.php Line 394-397

Paypal (new API) are implemented separately from generic Virtuemart payment methods. So we need to prevent it from reloading again

function list_payment_radio($selector, $payment_method_id, $horiz) {

...

$q = "SELECT payment_method_id,payment_method_discount, payment_method_discount_is_percent, payment_method_name from #__{vm}_payment_method WHERE ";
$q .= "(enable_processor='$selector' AND `payment_class`!='ps_paypal_api') AND ";
$q .= "payment_enabled='Y' AND ";
$q .= "vendor_id='$ps_vendor_id' AND ";

...

}

components/com_virtuemart/themes/default/templates/checkout/get_payment_method_paypal_ex.tpl.php Line 74-86

If you only use one payment method "Paypal (new API)", you need that payment method to be selected by default.

<fieldset><legend><strong>PayPal</strong></legend>
<table border="0" cellspacing="0" cellpadding="2" width="100%">
<tr>
<td style="vertical-align:middle;">
<input type="hidden" id="paypalExpress_ecm" name="payment_method_ppex" value="" />
<input type="radio" id="paypalExpressID_ecm" name="payment_method_id" value="<?php echo ps_paypal_api::getPaymentMethodId();?>" checked="true" />
</td>
<td>
<?php echo $html; ?>
</td>
</tr>
</table>
</fieldset>

This quick article has been taken from many comments and threads on the K2 community pages and forum, hopefully this will be obsolete when K2 2.5 comes out with these bugs fixed ??

These fixes are for the problem with the front end "add an article" pop up, popping up to big for users with lower res screens. 

The second fix is for the save button, that when clicked, does save the file, but doesn't close down the screen. I have both of these working with K2 2.4.1

These are bothhacks and you should remember that when you upgarde to a newer version of K2 these will/may be overwritten

---

First the SAVE BUTTON

go to components/com_k2/views/item/tmpl/form.php

After string 35: "submitform( pressbutton );"
You can add:
36: parent.$('sbox-window').close(); /* To close modalbox */
37: alert( ' Send ! ' ); /* To view a message */

 

---

 

Second - resizing the pop up screen

You will need to modify the following K2 core files:

components/com_k2/templates/user.php
components/com_k2/templates/default/category.php
components/com_k2/templates/default/item.php 

If you use custom K2 templates, then there is a little more you can do:
templates/YOURJOOMLATEMPLATE/html/com_k2/templates/user.php
templates/YOURJOOMLATEMPLATE/html/com_k2/templates/YOURK2THEME/category.php
templates/YOURJOOMLATEMPLATE/html/com_k2/templates/YOURK2THEME/item.php

You need to replace the "so famous" rel="{handler:'iframe',size:{x:990,y:650}}"

1) To alter the size of the window in the K2 Login module, find the Userblock.php file, found by; modules/mod_k2_login/tmpl/userblock.php. On or around line 35 (in mine, may vary in yours), find the line;

rel="{handler:'iframe',size:{x:990,y:650}}"

And replace it with this:

rel="{handler:'iframe',size:{x:window.getSize().scrollSize.x-80, y: window.getSize().size.y-80}, onShow:$('sbox-window').setStyles({'padding': 0})}"

In a few words, what this code does is resize the popup window (appears when you click "Add new item" from K2 Login module), conform to your window (not screen) resolution. Then you can see whole the window in a wide view. Well that's what I can see from my laptop. (1280x800)

Note: Maybe you will see many of this rel="{handler:'iframe',size:{x:990,y:650}}" well, just replace all of them to get the problem fixed.

If you want to do this with the component for a better font-end edit just follow these steps:

2)To alter the size of the window in the category add item link, again find the file "Category.php, item.php and User.php"
These can be found by; component/com_k2/templates/default/(category.php/item.php/user.php)
Again find the exact same line as before
rel="{handler:'iframe',size:{x:990,y:650}}" and replace it.

3) To alter the size of the modal window for the "Edit item" link, find the category_item.php file; found by: component/com_k2/templates/default/category_item.php
Do exactly the same as above.

Bonus - Remove the pop up all together and display in a normal window

You can disable the lightbox by removing the class and the rel.

Before:

class="modal" rel="{handler:'iframe',size:{x:window.getSize().scrollSize.x-80, y: window.getSize().size.y-80}, onShow:$('sbox-window').setStyles({'padding': 0})}" h r e f=" < ?php echo $user->profile->addLink; ?> " > < ?php echo JText::_('Add new item'); ? >< /a>

After:

h r e f="< ? php echo $user->profile->addLink; ?> " >

This way you will get a "normal" link to open in a same window or in a new tab.
Just remember remove the class="modal" because if you don't it will display a worst lightbox

I recently needed a simple way to inform users in countries that shipping is not set up as standard, to contact us for shipping costs. The standard message if there is no shipping set up is "Please Select a Shipping Method", which i s a bit annoying if there isn't one showing up and the user will go elsewhere.

Here's my simple solution to alter that text;

1. Go to /administrator/components/com_virtuemart/languages/common/english.php
2. download english.php and open in a text editor/ BBE/Dreamweaver
3. Line: 293 'PHPSHOP_CHECKOUT_ERR_NO_SHIP'.
4. Change the standard text "Please select a Shipping Method" to "whatever you want"
5. Save your file - with exact same name
6. Upload by FTP
7. Clear joomla site cache
8. Check in front end

To show Simple Attributes on the browse page, apply the following changes to Virtuemart:

After line 16 in addtocart_form.tpl.php (browse template, includes folder) add:

<?php echo $ps_product_attribute->list_advanced_attribute($product_id);?><br />

This shows the combobox for your simple attributes (for example: a color picker)

---

 

Around line 410 in shop.browse.php (administrator component, html folder) comment/remove the following bit:

&& !ps_product::product_has_attributes( $db_browse->f('product_id'), true )

leave the rest of the if statement alive
this shows the add to cart button, that is normally hidden when you have simple attributes set up.
