calling Zope objects from php
by Guy Redwood 25 Feb '01

Hi Just wanted to share this with you. We use the phorum bulletin board in php and Zope for the rest of our site (truly smitten with Zope). I've just realised how to add the menus and banner adverts (built in Zope) into the headers and footers of the bulletin board php scripts. I originally thought of embedding php into Zope... but it's easier to call zope from php! Use the 'include' function to call Zope dtml methods through http. Really easy.... <?php include ("http://www.siberianhuskyclub.com/banners/show_banner"); ?> This just places the code for our banner adverts in the right place. Guy http://www.siberianhuskyclub.com

The advantage of the reversed setup is that if you configure it that way then the "natural" way to access the site can be https and http is the special case and not the other way round. Ragnar

The idea come from the book "web application development with php4.0" by Ratschiller and Gerken. The web site is http://www.phpwizard.net/ The idea was to build an irc client. You may ask them wether it's a foolproof solution or not. Beside the fact that some browsers may have a timeout setting, I do not see why it wouldn't work. Philippe > Cool idea!

reinstall

Hi, I am running FreeBsd and I did a make install to upgrade my zope from 2.2 to 2.3. My validation is done by apache using the <directory> directive of the cgi- bin directory but it does not seem to work. I keep getting the error below. Can anyone give me any ideas on how to set it up again probably from scratch? Thanx. Zope Error Zope has encountered an error while publishing this resource.

FW: Reading properties from nested objects.
by Michael Van Cleave 25 Feb '01

25 Feb '01

I have am using something similar to the Yihaw Pointer in the Yihaw class to reference objects elsewhere in the folder structure of my site. The pointer has a property on it that stores the absolute url of an object that it is referencing. I cannot figure out how to use the stored absolute url to read elements off the remote object. >From an arbitrary dtml-method, how can I render a variable property on a remote object. For example in the following site structure /root /x index_html pointer_method (has a property "url" which is "/y/objectZ") /y objectZ The index_html file calls pointer_method and reads the property "url", creating a link to the object that "url" points to (objectZ). This works great. However, I would like to read properties off that remote item (say the title for example) and render them in the index_html file. I have tried this, but it generates a key error: <dtml-call "REQUEST.set('location', _.string.replace(pointer, '/', '.'))"> <dtml-var location.id> If I hard code it as such: <dtml-with y> <dtml-with objectZ> <dtml-var title> </dtml-with> </dtml-with> I can read the title, but I cannot figure out how to convert the absolute url into a with statement or a var. Any help is greatly appreciated. -m

Re: [Zope] sidebar sorting

In your example, it would use the attribute with the literal name "_.[sort]". But you want "_.[sort]" evaluated and use the result as sort specification. You can do that with "sort_expr" (rather than "sort"). Dieter

"in"'s sort does not support this.

RPM, python scripts, threads
by Philippe 24 Feb '01

I've got zope 2.3.0 running with python 1.5.2 on RedHat 6.2. I'm afraid the threads for python have not been compiled in. Is there an RPM that does it? (My system administrator will not let me install anything without an RPM. How difficult is it to write an RPM?) thanks a lot, -Philippe (Below, I'm including the page source of an error message trying the Guest_Book example of the Zope Book, which btw is an excellent book :-) <!-- Traceback (innermost last): File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 187, in publish File /usr/share/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 171, in publish File /usr/lib/python1.5/site-packages/ZPublisher/mapply.py, line 160, in mapply (Object: addEntryAction) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 112, in call_object (Object: addEntryAction) File /usr/share/zope/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: addEntryAction) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: addEntryAction) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_Util.py, line 334, in eval (Object: addEntry(guest_name, comments)) (Info: guest_name) File <string>, line 0, in ?

Xron question--why won't method work
by Chris Muldrow 24 Feb '01

24 Feb '01

Here's a clarified version of a question i asked earlier that is still stumping me. Why will this method work as a regular DTML Method but not as a Xron method: <dtml-in expr="objectValues('DTML Document')"> <dtml-let newname="'o13'"> <dtml-let nameadd=id> <dtml-let newname="nameadd+newname"> <dtml-let newtitle="'Chris'"> <dtml-let story=document_src> <dtml-let credate="ZopeTime()"> <dtml-with "PARENTS[0]"> <dtml-call expr="addFLSNews(newname, story, credate)"> </dtml-with> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-in> And here's the external method that it's calling: def addFLSNews(self, newid, data, REQUEST=None): """ """ # Get the actual destination object, using the this() # method, to be sure we get it in the right context.. self=self.this() # Create the new instance newob=self.Control_Panel.Products.FLSNewsStory.FLSNewsStory(data) newob._setId(newid) self._setObject(newid, newob) newob.title=getTitle(data) varStoryName=getStoryName(data) varUser=getUser(data) varPicID=getPicID(data) varCategory=getCategory(data) varLocality=getLocality(data) varBasket=getBasket(data) varNwords=getNwords(data) varEditionInfo=getEditionInfo(data) varSummary=getSummary(data) self._setProperty('User', varUser, type='string') self._setProperty('StoryName', varStoryName, type='string') self._setProperty('PicID', varPicID, type='string') self._setProperty('Category', varCategory, type='string') self._setProperty('Locality', varLocality, type='string') self._setProperty('Basket', varBasket, type='string') self._setProperty('Nwords', varNwords, type='string') self._setProperty('EditionInfo', varEditionInfo, type='string') self._setProperty('Summary', varSummary, type='string') It's hitting a problem at the self.setObject line. This method works when I run it as a regular DTML Document, but it hits an "Attribute Error on self.setObject when I run it as an Xron. I'm using the trigger tab, but I've also tried letting it run as scheduled--neither works.
