Joomla Virtuemart 2 plgVmOnSelectPayment() - php

How can I add a form or HTML output to plgVmOnSelectPayment()?
I see no documentation about that.
I don't know this event Virtuemart payment select works.
I want add after selection a form with input fields.
Can anyone help ?

The plgVmOnSelectPayment() from what I've reversed engineered doesn't give any output to the HTML, but you can modify the cart content with that event.
I was myself in need of adding a form after a particular payment method was selected (to guarantee some additional data being supplied). Depending on where you want it you can either edit the View for the cart and add an if-statement where you see if the particular payment method is chosen. And then later access this information from plgVmConfirmedOrder() (you can access it through the $_POST global.
(This is an untested theory)
If you want to add the information to the field you can access the display form and add information there through the plgVmDisplayListFEPayment() event. Look in the vmPSPlugin class to see how they manage it there. What I did was simply copy that to get an image into that form, but you should be able to add other things there as well. And then you might be able to access the information there through plgVmOnSelectPayment() and using the $_POST global.
As a fair warning. All this I've gotten through reverse engineering VirtueMart. So it's neither pictue perfect nor might it be best practice. But the VirtueMart documentation leave not many other options :(. So if someone have a better way, I'm very interested in knowing that as well!

let user disable certain array items?

This is the situation, I've got a big array ( 280 items ) which creates a really big form by going trough loops.
I want the user to be able to disable certain items, so they can 'pre make' their form ( and skip the not used ones ), You are probably going to say i can just remove what's not needed. But they need different items from the array every time they use it.
So how would i make a page where they can just use checkbox to 'change' the form. ( if possible at all.)
Thanks,
Mike

Did not think of sharing code, here:

Might be a bit messy. I'm new in PHP, and only programming for a year. Also dont mind the language please.
If you want to permanently record form preferences/settings for each user, you'd want to create an additional table or column(s) in your database for this, give the users additional checkboxes on the form to indicate their preferences, receive this input and store it in the database, and of course finally disable certain fields based on their settings.
But if you just want to give the users a temporary way to disable certain fields (with no preferences saved permanently), you would use JavaScript in your output. You would add more form controls (checkboxes or buttons or whatever) to the HTML and then add JavaScript code snippets into that HTML to disable form elements when the user clicked on the controls. This kind of making changes when users click is called "triggers that fire based on events". The most commonly-used event is called "OnClick()" and the JavaScript code for it will execute when a user clicks on something.
Many folks who use JavaScript also find it helpful to use the functions in the jQuery library instead of raw JavaScript. To do this, you just add one line of HTML to the top of your page to include the JavaScript libraries from a publicly-hosted server, then you can use jQuery commands in your page.
The only thing to remember when you first start using JavaScript/jQuery is that it only runs on the client browser - its code cannot talk directly to the server, the database, or many things you can access in PHP. JavaScript/jQuery is specifically used for making your HTML pages more interactive. Plain HTML doesn't have much razzle-dazzle. JavaScript allows users to do things like enable and disable form fields on-the-fly.

How do I make a custom <form> element be used in place of a <form> in a pre-existing plugin?

I am customizing a theme and a plugin in Wordpress. The plugin has a button where a user can click to bring up a form where they can ask a question. I want users to use post questions through this button on this plugin, but I don't fancy the visuals on it. So I thought I'd make a form on my landing page that will post into the plugin's form. If this is a terrible idea in the long run, please feel free to let me know because I am still new to web dev.
So the goal is to create a new form whose aesthetics are to my liking but still use the plugin's built in posting capability. How do I make my form paste into the plugin's form and then submit it? You'll notice that my form has 1 additional field: the add money field. I also need to integrate this into the plugin. If anyone know how to begin modifying the code for this I'm all ears to anything I need to start reading or a general way of how to approach this.
My form
Plugin's form
Summary:
Need to have my form paste to plugn form and submit
Need to add a field to the plugin code that my form can post to similar to how the other fields will do do
You can post from a different form if you get the destination URL or javascript that is handling the original form post. You can use the debugger in Firefox or Chrome to inspect the page contents to see how the form is handled.
Adding the money field will be more complicated because you will need to update the server side handling to accept the additional parameter so that it is not simply ignored or causing errors. How much work this is depends on what the server has to do. It may involve adding a column to the database or creating a new table which you will likely want to do the wordpress way if you want to have something that is maintainable.
Lastly keep in mind, that every time the original plugin is updated, it may bust your add on code unless you create your own plugin from the original.

Joomla form variable handling

I have a situation where I need to create a shortcut for a specific filter in a Joomla component.
The problem is that I cannot unset it, as I do not know if Joomla sets the form fields to its own session handler, request handler or some kind of custom handler. There also does not appear to be any documentation on this specific case.
The full situation is that I have a link that will auto filter in the same view as another link (in the components sidebar). One view will be just a specific filter and the other is standard. So I need it when you click into the filtered view it will reset the current filters to make sure everything displays as it should, and vice-versa so clicking back will again reset the filters.
I have tried a number of approaches for this, and although I can consistently force it to filter but it will not reset the form when I re-enter the last page with any technique I have tried so far and of course I want to avoid bypassing Joomla's default functions.
if(JRequest::getVar('filter_group_id',false)==10){
JRequest::setVar('last_filter',true);
EthicstoolHelper::addSubmenu('supervisors');
}else{
if(JRequest::getVar('last_filter',false)===true){
JRequest::setVar('last_filter',false);
JRequest::setVar('filter_group_id',false)
}
EthicstoolHelper::addSubmenu('users');
}
This is the most recent think I have tried, as you can see I try to reset the value to false in a hope that Joomla will read it as not being set, as JRequest has no built in unset method.
I don't have enough rep to comment yet, so I'm guessing a bit as to what the problem could be. Assuming that you are using a model to set the state of the filters, you can look at overriding the populateState method.
Another options is to fiddle with the context property in the model. For example, you could change the context if you have your special filters enabled if you are using things like $app->getUserStateFromRequest(). If you can post a bit more information about the design of your component (controllers and models), I can help more.

Drupal, ajax, ubercart question

Thanks in advance for your help. I'm completely stumped on how I can do this.
Here is my issue.
I have a node type show;
Each show has a number of performance dates and times.
When the user clicks "purchase tickets" from a show's page, I need to show them a single page, where the following happens:
The top of the page has a calendar that has dates and times available for this show highlighted. The user can then pick a date and time for this show that he wants to see. He can pick multiple dates and times.
Once he picks and date and time, I add them to a "cart" using ajax. The user can then enter the number of tickets that he wants for each performance.
Finally, on the bottom of the page he enters his checkout information (name, address, credit card etc) and is then pointed to a confirmation page. This is not done by ajax. Finally he authorizes the transaction and check out. (I'm using UberCart, but nothing else tied in, so I can switch if needed).
This is driving me nuts. I have no idea how to pull this off. Not even where to get started. Can someone please help?
What you want to do, is going to be quite hard and wont work well with ubercart, since you want to make a single add to cart and checkout page.
Ubercart will by default allow users to add items to their cart, and would also by default create a checkout flow, but you want something complete different than what ubercart offers. You might want to rethink your approach and either choose a flow that works better with ubercart or choose a different solution that by default works better with what you want (if there is such a thing).
What you can do
To do what you describe, you would need to create a custom page, that shows the calendar with the shows, some javascript to hand the ajax and a checkout form.
Behind the scenes you need to generate the calendar with the appropriate days (the date module might help you), respond to the ajax requests and add items to the basket, handle the checkout flow/order status and redirect to payment form or handle payment as well.
All of this would need to happen in a custom module, you would need to use hook_menu to create the page, that would take the product node as argument. You can use that in your callback function to generate the calendar. You would also need to create a callback for the ajax and add the actual javascript to do all the magic.

Multi page ordering form php or ajax

I'm looking to create a multi page ordering form the first page would contain some dropdown and text fields, the second page would contain more text fields, the third page would be an order summery with paypal payment option.
I'm just wondering what the best way to create this order form is. I've used sessions in the past but never with users entering in text and picking items from drop downs, does anyone have any resources for doing this? Or does anyone know of a jquery or other ajax example or plugin I might be able to use and modify.
any insight would be a big help.
thanks
The simplest technique might be to use hidden form fields to carry fields from previous screens through to the final screen.
Just make sure you validate all the values when the final screen is submitted to make sure that the user hasn't twiddled the data.
You don't need to do pagination at all if you don't won't to. Just use css to show/hide the "pages". It doesn't sound like you have to save the "state" at any point.
But if you want to do multiple pages, use a session or a cookie to track the user. Then save the data to a database a mark it as incomplete. On the final page, retrieve it all and show it on the page. The server can't tell if a request is ajax or not, so it doesn't matter what you use for submission.
