Add to Cart from Search Page

I am adding a requested function to the SearchScan.tpl. My photographers asked if I could put a link on the search page so that they can add their photos to the cart with out having to click on the thumbnail witch takes them to the photo in the album.

I did this but the problem is that everybody can see the link Add to Cart. Not everyone has this permission.

How can I set up a quick check on the user permissions? If the user has the add to cart permission then show this link. If not don't show it.

Here is the code I am using in the tpl

<p>
<div class="gbBlock">
<a href="{g->url arg1="controller=cart.AddToCart" arg3="itemId=`$itemId`"}">
{g->text text="Add to Cart"}
</a>
</div>
</p>

Can I use something like
{if isset($theme.permissions.core_addDataItem)}
instead of addDataItem what ever the cart permission check is.

Thanks

It looks like the only kind of permissions is for what images can be viewed.
No systemlinks or itemlinks permissions are being past.

I believe the some sort of array for system and item links permissions need to be in the SearchScan.inc
But I don't know enough to be able to code that into the SearchScan.inc with out over coding it. Or just plain messing it up.

I looked at the Metrix theme.inc to see how it calls the links permissions but don't know what code to copy with out braking the SearchScan

Thanks
You help is greatly appreciated.

Thanks for the heads up.
I took the following from GalleryTheme and put it in the SearchScan.inc Just above the /* Render the HTML body */

/*
* --------------------------------------------------------------------------------------

*/

$theme =& $template->getVariableByReference('theme');
$load = $childItems = $childData = array();

}
}

* don't lead to multiple database queries.
*/

if ($ret->isError()) {
return $ret->wrap(__FILE__, __LINE__);
}
}

if (isset($load['itemNavigator'])) {
$navigator = array();

return $ret->wrap(__FILE__, __LINE__);
}

foreach (array_keys($permissions) as $perm) {
$theme['permissions'][str_replace('.', '_', $perm)] = 1;
}
}

And I am using the following in the SearchScan.tpl
<div class="gbBlock">
{if isset($theme.permissions.core_SystemLinks)}
<a href="{g->url arg1="controller=cart.AddToCart" arg2="itemId=`$itemId`"}">
{g->text text="Add %s to Cart" arg1=$itemId.title|markup}
</a>
</div>{/if}

I am still getting the same results as before I put the permissions code in the SearchScan.inc.
The link doesn't show up for anybody including Admins
I also tryed using ItemLinks with no luck.

Any ideas?

Thanks for your help.

whoa, i was thinking just:

$searchResultIds = /* whatever in SearchScan.inc that is an array of ids of the search results */ ;
$ret = GalleryCoreApi::studyPermissions($searchResultIds);
if ($ret->isError()) {
    return $ret->wrap(__FILE__, __LINE__);
}
foreach ($searchResultIds as $itemId) {
    list ($ret, $permissions) =
        GalleryCoreApi::getPermissions($itemId, $theme['actingUserId']);
    if ($ret->isError()) {
        return $ret->wrap(__FILE__, __LINE__);
    }
    foreach (array_keys($permissions) as $perm) {
        $data[$itemId][str_replace('.', '_', $perm)] = 1;
    }
}
$template->setVariable('itemPermissions', $data);

not enough info to help there...
what code did you use? where did you put it? how did it get into GalleryTheme.class? (the code i posted doesn't call GalleryTheme)

I wrote:
$searchResultIds = /* whatever in SearchScan.inc that is an array of ids of the search results */ ;

You wrote:
$searchResultIds = 'itemId';

Hmm...

right, that's a comment telling you to figure out how SearchScan.inc works and replace that comment with the right bit of data..

I am still just guessing but I think that the arrary you are taking about in SearchScan.inc.
is

	    /* Pull out all the item ids and save them */
	    $itemIds = array();
	    foreach ($searchResults as $id => $resultSet) {
		foreach ($resultSet['results'] as $result) {
		    if (isset($result['itemId'])) {
			$itemIds[$result['itemId']] = 1;
		    }
		}
	    }
	    $itemIds = array_keys($itemIds);

I just tryed the following in the $searchResultIds = line

	$searchResultIds = array();
	    foreach ($searchResults as $id => $resultSet) {
		foreach ($resultSet['results'] as $result) {
		    if (isset($result['itemId'])) {
			$itemIds[$result['itemId']] = 1;
		    }
		}
	    }
	    $searchResultIds = array_keys($searchResultIds);

I still get the following error.

Fatal error: Call to a member function on a non-object in /srv/www/htdocs/gallery2/modules/core/classes/GalleryTheme.class on line 690

Am I at least looking at the right bit of code or am I WAY OFF?

from the first post, looks like you found the right variable.. just do:
$searchResultIds = $itemIds;
as the first line of your added code.

Run the upgrader up to step 2 and see what files it says are modified. Maybe you edited GalleryTheme.class at some point and left an error in there.

Here is the whole SearchScan.inc that I am using.

$searchResultIds = '$itemIds';
probably should read up on how php works..

take out the quotes again, wrap your whole block of added code inside
if (!empty($itemIds)) {
and
}

you're on your own debugging the GalleryTheme error..

I moved the code to a different place in the SearchScan.inc. And this got rid of the itemIds error.

	    /* Pull out all the item ids and save them */
	    $itemIds = array();
	    foreach ($searchResults as $id => $resultSet) {
		foreach ($resultSet['results'] as $result) {
		    if (isset($result['itemId'])) {
			$itemIds[$result['itemId']] = 1;
		    }
		}
	    }
	/* check permissions */

	$searchResultIds = $itemIds;
	if (!empty($itemIds)) {
 	$ret = GalleryCoreApi::studyPermissions($searchResultIds);
	if ($ret->isError()) {
		return $ret->wrap(__FILE__, __LINE__);
	}

	foreach ($searchResultIds as $itemId) {
    		list ($ret, $permissions) =
        		GalleryCoreApi::getPermissions($itemId, $theme['actingUserId']);
		if ($ret->isError()) {
    	    		return $ret->wrap(__FILE__, __LINE__);
    		}

    	foreach (array_keys($permissions) as $perm) {
     	   		$data[$itemId][str_replace('.', '_', $perm)] = 1;
    		}
	}
	}
 	$template->setVariable('itemPermissions', $data); 
 

	    $itemIds = array_keys($itemIds);

But I am still getting the following error after I do a search for something.

Notice: Undefined variable: theme in /srv/www/htdocs/gallery2/modules/search/SearchScan.inc on line 205

Notice: Undefined variable: theme in /srv/www/htdocs/gallery2/modules/search/SearchScan.inc on line 205

That got rid of the theme error but the data error is still coming up.

I removed the $data and the error went away but the permissions still didn't work right in the SearchScan.tpl.
$template->setVariable('itemPermissions');

tpl code is as follows.

<p>
        <div class="gbBlock">
	   {if isset($theme.Permissions.cart_AddToCart)} 
          <a href="{g->url arg1="controller=cart.AddToCart" arg2="itemId=`$itemId`"}">
            {g->text text="Add to Cart"}
          </a>
        </div> 
           {/if} 
	</p>

I also tryed
{if isset($theme.Permissions.core_AddToCart)}

both do work in a way. It doesn't show the link to anybody.

THANKS...
That got rid of the data error.

But I still can't get the tpl permissions code to show the link.

I've tryed to use
{if isset($itemId.Permissions.cart_AddToCart)}
With no luck

No I don't know exactly how it translates into a tpl.

I have attached the debug file.

Not sure what to look for.

I do see where it has called some Cart stuff but I think that might be from the SideBar.

I forgot to allow popups from my server.
Sorry.

Here is the popup.

I did a debug on an album page and it looks like I am missing a call to the permissions array in the SearchScan.inc.
In the {$theme} part of the debug at the bottom is where the permissions are called.

I tryed to add a line just after the $data = array(); called $permissions array(); but that didn't work.

permissions => Array (11)
  core_all => 1
  core_view => 1
  core_viewResizes => 1
  core_viewSource => 1
  core_viewAll => 1
  core_addAlbumItem => 1
  core_addDataItem => 1
  core_edit => 1
  core_changePermissions => 1
  core_delete => 1
  cart_add => 1
columnWidthPct => 25

change
$searchResultIds = $itemIds;
to
$searchResultIds = array_keys($itemIds);

oops, missed that there is already $itemIds = array_keys($itemIds).. of course you don't need to do it again. $searchResultIds = $itemIds is correct.
spend some time debugging this.. add some print statements at various places in the code to make sure the variables have the values you think they should have, then you can determine where things go wrong. if you're not sure what values the variables should have, spend some time to understand what this code does.

uh, what is $itemId['actingUserId']? i'll leave it to you to figure out what should go there.. check the phpdoc for that core api.

How can I use the print_r with the if?

{if !isset($theme.Permissions.cart_add)}

Hi

Did either of you get this working?
