hello,
i do display a specific class of objects on my frontpage (using a myclass_line.tpl file) and want to shorten the title and the intro to keep the design in place. as far as i understand the shorten operator, i tried all the versions to make that work - with no success. any suggestions?
it works fine with:
{$node.name|shorten(30)}
but not with:
<a href={$node.url_alias|ezurl}>{attribute_view_gui attribute=$node.object.data_map.teaser|shorten(120)}</a>
maybe i do have to change another template, but i don't know which that could be.
thank you very much in advance.
stefan

If the teaser attribute is simple text, try EDITED: wrong
<a href={$node.url_alias|ezurl}>{attribute_view_gui attribute=$node.object.data_map.teaser.content|shorten(120)}</a>
EDITED: right
<a href={$node.url_alias|ezurl}>{$node.object.data_map.teaser.content|shorten(120)}</a>
If it is xml text, you will first have top strip the xhtml tags before shortening, otherwise your pages may become broken xhtml wise. hth -paul

dear paul,
your version does not work either. instead of not showing a shortened version, your version produces no output at all with my templates.
the only version that works is by setting a length-limit in the admin-classes-tool. i thought there is another possibility though, since i want to show a shortened version on my frontpage, but the full teaser on the details page... atb, stefan

For a text line field (probably your title) try something like this: <a href={$node.url_alias|ezurl}>{$node.object.data_map.title.content|shorten(120)}</a> and for XML field (probably the intro): <a href={$node.url_alias|ezurl}>{$node.object.data_map.intro.data_text|shorten(120)}</a> but strip the XML tags first.

Same problem.. I want to shorten this:
{attribute_view_gui attribute=$node.object.data_map.intro}
Tried writing:
{attribute_view_gui attribute=$node.object.data_map.intro|shorten(10)}
Then like it was mentioned here:
{$node.object.data_map.intro.data_text|shorten(10)}
Nothing works... Anyone with an idea?

What does "Nothing works..." exactly mean? Is the text displayed incorrectly or not displayed at all. Please specify.

With "Nothing works..." I mean that none of the above solutions works.
None of them display anything. As long as I add the |shorten(#) command, it shows nothing...

Try checking out if $node.object.data_map.intro.data_text relly exists and what type is it,like this:
{$node.object.data_map.intro|attribute(show)}
If you ommit the shorten operator and put just:
{$node.object.data_map.intro.data_text}
is the text displayed?

on your first suggestion, ez crahes and reports a fatal error.
the second line of code produces no output at all. i solved the problem by creating an "textline"-style attribute allowing no more than 120 letters length. its not the best version i believe, but a working one... regards, stefan

"i solved the problem by creating an "textline"-style attribute allowing no more than 120 letters length. its not the best version i believe, but a working one..." How did you do this? Could you put up a sample of that code?
Thanx,
Siw

actually, there is no code as such. i created a new class that has five attributes. one of them is the "teaser". i made it a textline since you can add a maximum length. in characters. all via the web-gui. i know that it is not the solution to the problem, but i had to figure out something since the project is due in two weeks... greetings, stefan

> on your first suggestion, ez crahes and reports a fatal error.
> the second line of code produces no output at all. If the EZ crashes then could be something really wrong. Try this variant:
{$node.object.data_map.intro|attribute(show,1)}
One question? Does the class of the $node contain the intro attribute. If not then, you should substitute "intro" in the above code with the attribute that contains (e.g. "teaser"). And then try:
{$node.object.data_map.teaser.data_text}
if teaser is XML field, or:
{$node.object.data_map.teaser.content}
if tesaer is a text line. And of course, first fill tesaer with some test data like "Hello World" :)
Then report what happens.

since i cannot mess around with the content some editors have published already, i created a new attribute "test" to my class. i tried your code, this happened: with the ...|attribute(show,1)
ez prints out a table with a header "attribute", "type" and "value". the fields are empty though. since it is a xml-textfield, i tried {$node.object.data_map.teaser.data_text}
. this prints out the content i had previously entered for "test". since this works (it always did by the way), i tried the shorten-operator. again, this had only the effect that the content disappeared. can you conclude anything from this? greetings, stefan

Did the content disappear in your web page completely (also when viewing the source)? Also, could you post more of the template code, I suspect that you have syntax errors somewhere as you state that the shorten operator works on $node.name Again, you can <b>not</b> use the shorten operator on xml/xhtml output without stripping the xml tags first. The latter can be done easily with adding the striptags operator as its direct php counterpart in template.ini: PHPOperatorList[striptags]=strip_tags If your teaser text field is xml text, the following should work: {$node.object.data_map.teaser.content.output.output_text|striptags|shorten(60)} {$node.object.data_map.teaser.content.output.output_text} will give you the xhtml output of the xml you entered there and this is better to feed to striptags than the raw xml -paul
