Re: [fw-general] Passing an array from PHP to Javascript
that's what JSON is for. It's a serialized javascript array, so you simply serialize the array in javascript, pass it through to your PHP app, and there are JSON tools in PHP to instantly decode / encode the arrays. http://www.php.net/json for more info!

Re: [fw-general] Passing an array from PHP to Javascript
Thanks for the tips. But i CAN'T apply any of them now. The design has been
approved and i need to i implement things as they are. 'Over engineered' - I
dont care. As long my code works as expected. I simply want to pass my PHP
array into my javascript function. - very simple code i dont see why i need
to implement a library just for that.

As a general bit of advice, I would never do any destructive with GET
requests (e.g. manipulating the URL and redirecting via window.location).
If you need to do it fully in javascript, look at some kind of AJAX call
that can do POSTs (my preference is jquery, but dojo may be preferred
with ZF...)
But, really this is over engineered and you should look at a different
approach.. here is my hint:
1. Just use a normal form. Have all the checkboxes and the Delete
Selected button on the same form.
2. POST said form (do not use GET).
3. If you want to give the user a chance to backout with a javascript
confirmation, define an onsubmit handler for the form. Depending on what
this handler returns, the browser will either process or cancel the form
submission. So you in it's most basic form:
form method=post action=myurl onsubmit=return confirm('Are you
sure?');
That should be better!
Oh, and just for future reference if you want to pass arrays or generic
classes to javascript from php, you want to look into JSON and
specifically the json_encode() function (although there may be a ZF
wrapped up version - not sure!)

There are several things wrong with this statement...
In any event, if you want to share data between PHP and JavaScript, look at
Zend_Json and JSON in general.

Re: [fw-general] Passing an array from PHP to Javascript
hi Colin, My apologies if i came out as been naive and ungrateful. I was just under a lot of presssure here and just wanted a quick fix - my apologies sincerely. After taking a break off the work load and having my mind cleared i feel so stupid for such a reply from me. So i retract my initial comment. Thanks for taking the time to elaborate on the possible way of going about this. I will take some time to implement something - based on your suggestions and let you know the outcome. Thanks once again and my apologies Colin Guthrie-6 wrote: dele454 wrote: Thanks for the tips. But i CAN'T apply any of them now.

I wasn't suggesting you change the visual design, or do you mean a different kind of design? Do you allow the user to select some pictures and not others?

I have explained also how to pass a PHP array into JS, but as I said before, this is almost certainly not what you want to do to achieve this kind of interface. What you actually have is a list of selected items in javascript and you want to pass that back to PHP as an array! it's precisely the other way around.

Re: [fw-general] Passing an array from PHP to Javascript
I see exactly what you have been saying - again my mind was too saturated to see clearly! :( Anyway, just to reply one some of the questions you asked. The intention is that the user can either delete the picture indivually using the delete button next to each picture or select all and delete all. - but at the same time the user could deselect some pics - the intention is such that the user can delete a lot of pics at once. The reason my URL looks like am using a GET method is because the delete button is not a button but a link. the full view of my design is this just to explain a bit more: http://www.nabble.com/file/p19520252/untitled-2.gif I see what am doing wrong now - just to butress on your suggestions, i need to make that 'delete' button an actual button not a link - so the form can actually get submitted naturally via the POST method. From my controller retrieve the delete[] and iterate for deletion. I see clearly now. I think i got confused along the line while coding. Colin Guthrie-6 wrote: dele454 wrote: Thanks for the tips.

Re: [fw-general] Passing an array from PHP to Javascript
Hi Colin, Am not really bent of having the form process on GET. My forms use the POST method and i am changing it to GET. I simply used the URL path i posted earlier as a way of idenitfying which of the pics need to be deleted as a parameter. Colin Guthrie-6 wrote: dele454 wrote: I see exactly what you have been saying - again my mind was too saturated to see clearly! :( Anyway, just to reply one some of the questions you asked.

From my controller retrieve the delete[] and iterate for deletion. I see clearly now. I think i got confused along the line while coding. That's OK, and don't worry about the initial reply, it happens to us all from time to time. You could still keep you delete button as a link if you like. If you have the form, you can just do something like form id=myform method=get action=/my/url/handler input type=checkbox name=delete[] value=123 / input type=checkbox name=delete[] value=456 / input type=checkbox name=delete[] value=789 / etc. /form # Delete Selected That should then post your form to the following URL: /my/url/handler?delete[]=123delete[]=456 (assuming the first two checkboxes are selected and the third is not). This value will appear in PHP's $_GET array and in the ZendFrameworks request object as an array containing two numbers, 123 and 456. This is pretty much exactly what you want I believe and shouldn't require much in the way of reengineering. All that said, it's still a good general rule not to do anything destructive with GET requests and links, the reason being that some browsers could (for example) preload links (it wouldn't happen here as there is javascript involved). If, however you use simple GET links to delete the individual images in your gallery, of the form: /my/url/handler?delete[]=123 Delete this image Then it is *very* possible a browser could try and preload that URL when you visit the page (remember that the AVG antivirus tool used to preload all the links on a page!) This is why anything destructive should only be done via a POST. Hope this helps.
