Quick fix: where to?

[vediovis]

Hi everybody

First, I want to say how I’m impressed by egroupware. The tool is very nice, congratulations to everybody.

I need to implement 2 functionalities next week, and after a quick look inside the code, I decided to ask the forum how to do it and where to start. Both functionalities concern the address book part. I’m ZCE so I know PHP, but it will be the first time I will have to go inside egroupware’s code.

The first functionality is to add an icon in the tool bar near the “csv export”. A click on this icon will blow the content of a custom field previously created. So the click on this icon will call a query to delete every line from egw_addressbook_extra where contact_name=‘myCustomField’. Then screen will be reloaded exactly like it was before (except of course the custom field column which will be empty).

The second functionality will be to generate a pdf based on the same system than the csv export functionalities we already have.

First question and just to confirm: I hope the licence is ok and allow me to put my hands inside the code and to start hacking and coding inside.

Second question: where do I start? The central html comes from class.etemplate.inc.php line 215. Do I put my hands directly in there or should I start somewhere else?

Third question: just to know, how long it should take to do both?

Thanks by advance for your answers, and I wish a good week end to everybody.

Cheers

Stef

"csv
export". A click on this icon will blow the content of a custom field
previously created.

etemplate/inc/class.nextmatch_widget.inc.php
Icon should be added in its template through the eTemplate editor.

The second functionality will be to generate a pdf based on the same
system
than the csv export functionalities we already have.

I have no idea how you would do this. I’d guess tack it on to the
importexport stuff, which I think is responsible for the CSVs.

Hack away.

Third question: just to know, how long it should take to do both?

First one, about an hour if you know what you’re doing.
Probably 1.5 days since you’re just getting into it.
Depends how nice you want to be. If it’s always one column, and you
want to hard code that, it’s easier than if you want to add the icon
into a custom field header to clear any custom field.

Second one, no idea.

etemplate/inc/class.nextmatch_widget.inc.php
Icon should be added in its template through the eTemplate editor.

I, at least, succeded to find and launch the etemplate. I understood how it works and I added my icon as a submitbutton.

After, every template is associated to a controller class. So I could launch my action linked to my icon.

Only points:

• I need to display this icon only for the administrator login, not for usual users. I’m still looking for how to do it.
• It would be nice if I could display an event message to tell the user the action occurred nicely or failed. I’m pretty sure there’s a var to set somewhere to display event messages.

The second functionality will be to generate a pdf based on the same
system than the csv export functionalities we already have.

I will try to hack the CSV export part as the job is quite similar.

Hack away.

Yeah : )

Sure.

Thanks Nathan. It really helps.

Try the disable field, and set a variable accordingly.
$GLOBALS[‘egw’]->acl has some methods for you to check the ACL.
Alternatively, you can check the groups the current user is a member
of with one of the methods in $GLOBALS[‘egw’]->account.

set a variable accordingly.

Where?

I tried to go inside every method of the nextmatch_widget class, but it seems I can’t catch the cell in any “pre” process.

The template updated is etemplate.nextmatch_widget.nm_row but it has no PHP class associated. I found only the class nextmatch_widget class and it takes care about the content of the form, not about the header and the top part of the central table.

Thanks to you, I put my hands more and more inside this tool. I have to say there are good things here and it will be very powerful once I will know it better.

Cheers

addendum: For now I use a hardcoded test inside the html::image with test on $name and $GLOBALS[‘egw’]->acl->account_id. Quite dirty, but it does the job.
But I know it’s wrong. I should find the controller associated to the nextmatch_widget.nm_row and put the test inside so I can block the image + the link.

I assume you have your nextmatch otherwise working correctly.

I recommend to follow the examples of no_cat, no_filter. See
etemplate/inc/class.nextmatch_widget.inc.php line 436. These are
specified by the calling function and passed in $value. You can set
your button to always off, except if there’s a custom field and
permission, or you can turn it off by setting something in $value.

Hi Nathan

Thanks for your time., I see your name everywhere inside the software, I’m happy to have you replying my questions

I assume you have your nextmatch otherwise working correctly.

Everything works fine. Even my dirty fix

See etemplate/inc/class.nextmatch_widget.inc.php line 436.

I gave a try to this pre_process() the other day. The point is the tool bar is not managed by this part. I made some print_r of every params received by the method, and after I searched for them in the generated html. The button details never pass there.

I created the button with the etemplate application. I check its ID and name, or the pic file name. These elements never appear inside this method. I managed to catch them inside html::image , but I am not able to find them inside nextmatch_widget->pre_process()

It would help if I could as the test should be located in a pre_something somewhere, in a controller in charge of the etemplate.nextmatch_widget.nm_row template.

Notice: the template etemplate.nextmatch_widget.nm_row manages only the tool bar with the buttons First, Left, Ritgh, Last, exprt csv, etc…

Thanks for your time., I see your name everywhere inside the

happy to have you replying my questions

I think you may have me confused with someone who speaks German…

See etemplate/inc/class.nextmatch_widget.inc.php line 436.

I gave a try to this pre_process() the other day. The point is the
tool bar
is not managed by this part. I made some print_r of every params
received by
the method, and after I searched for them in the generated html. The
button
details never pass there.

What details specifically are you looking for?
You may have the direction backwards, as that’s one place where the
details are set.

So one option would be to check the permissions, then disable your
button with something like:
$nextmatch->disable_cells(‘button_name’,true);

Then the template generator continues to do its thing, turning the
template into HTML.

The other place details are set is in your calling function where you
specify the parameters for the nextmatch.
The disabling would be the same as above, but you would do your
checks, and pass in whether or not you wanted to disable the button:
$nextmatch->disable_cells(‘button_name’,$value[‘no_delete_button’]);

Notice: the template etemplate.nextmatch_widget.nm_row manages only
the tool
bar with the buttons First, Left, Ritgh, Last, exprt csv, etc…

Is this not where you have placed your button?

add an icon in the tool bar near the “csv export”.

Things are different if your button is somewhere else.

$nextmatch->disable_cells(‘button_name’,true);

You re right. Perfect, and clean. It’s exactly where it should be. I just didn’t know how to.

Thanks Nathan. I’m ok to do things now. I create buttons regards to the loggin, and I associate actions like CSV and PDF or DB writings.

Errrr, any chance to have a way to pass ab event message for the web form, something like for example: “everything was ok”. Do I need to create a label and to give it a value in the preProcess, or is it already prepared somewhere?

Thanks again

Stef

You’re welcome.

That I’m not sure of, and it would depend on where you’re handling the
action.
If the action is handled in your application, you can do whatever you
want. I’m a fan of the label.
If the action is handled in post_process, you might be more limited in
what kind of response you can give.
If you’re working with an eGW app, you can try setting a $_GET[‘msg’],
I think.
