Add To Cart POST goes to blank page.

[deejayspinz]

Hi,

I installed the plugin and setup a number of products on a page. When I click the Add to Cart button, I get a blank page with “Page Cannot Be Displayed Error. HTTP 405 – Resource not allowed.”. I did some digging and “think” it may have to do with the Action postback going to the cart (eg Action=””). For example, I modified the line:

$replacement = ‘<object><form method=”post” action=”” style=”display:inline” onsubmit=”return ReadForm(this, true);”>’;

To (see the action parameter):

$replacement = ‘<object><form method=”post” action=”index.php?page_id=839″ style=”display:inline” onsubmit=”return ReadForm(this, true);”>’;

However, the problem is that this seems like an odd way to fix something that may have an easier answer, and I am not even sure its a fix. Currently I have the Add to Cart and View Cart links on the same page. When I use the above tweak, I can add to cart, it refreshes and shows the cart contents on the same page, but again, I dont know if this is a real fix or if it breaks something else.

A side note about my site. The contents of my WP site are within a subfolder (eg /Wordpress) and I have changed the site (as suggested in WP docs) to allow me to call from the root (www.plastibots.com). I moved the index.php file to the root as suggested. The site is working fine with this change.

Help!

It’s good to know that you got it working by tweaking it but you really shouldn’t have to do any tweaking. I don’t know exactly what you did for your specific wordpress setup but I suspect some steps might be missing. I have a few customers who installed thier wordpress in a sub-directory then used redirection to access it from the root domain.

The changes you did shouldn’t break anything else but it can be limiting as you are specifically posting to a page. action="" means post to the current page (whatever this page maybe)

Problem is, it is not really working. I think that normally, WordPress handles my site calls to the root at index.php. For example, my About page calls to this: http://www.plastibots.com/?page_id=2 (WP and IIS are fine). But, in your plugin action=”” and calls back to the same page seem to break. Any other thoughts on how to fix this? I dont really want to patch the action reference as it seems more like a bandage solution.

deejayspinz – looks like you are hosting on IIS as well — did you ever get this working. I’m using a 404 handler for better URL formats and this broke the paypal shopping cart. I can’t figure out how to input the correct settings to get it to work.

@timheuer, I got it working, but noting being a PHP guru, I feel like it’s a bandage solution. My first post alluded to the fix, however after testing it, I also noticed that the red ‘x’ to delete an item from the cart was also broke, so I had to do a similar fix for that. I have posted the updates I made below, but remember that these may not be the proper fix and it would be better if they are fixed by an official update to the plugin.

In a nutshell I think the problem I am having is a combination of IIS, and permalinks (I cannot get permalinks working with anything other than forcing /index.php?page=). Oh and I also followed the WordPress notes to move my index.php out of the wordpress folder and into the root of the site. So I think that all of these tweaks are playing a role here.

That said, here are the mods I made to wp_shopping_cart.php (change your pageid to be

the pageid for your blog. In my case the products and cart are both on the same page:

Within the block of code beginning on line 222 that starts with $output .= ”

There are two calls to action=””

I modified each to include a reference to index.php?page_id=839 and they look like this: action=”index.php?page_id=839″ Make sure you get the and ” in the right place.

approx line 441:

Change:

//$replacement = ‘<object><form method=”post” action=”” style=”display:inline” onsubmit=”return ReadForm(this, true);”>’;

To:

$replacement = ‘<object><form method=”post” action=”index.php?page_id=839″ style=”display:inline” onsubmit=”return ReadForm(this, true);”>’;

Once I made these changes, the cart appears to be working ok. However, Im screwed if I change the page, or add the cart elsewhere.. I will cross that bridge if and when I have to..

@deejayspinz – thanks — I tried that but still isn’t working for me — I wonder because I have the cart in a page that is within a category? Do you have yours in a public place I can look? Mine is here: http://cortinahoa.com/documents/online-payment

I just tried your link and your cart seems to work fine. (I only added and removed from the cart).
