shorten operator with viewing attributes?

Friday 24 September 2004 1:40:53 am

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.

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.

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

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?

"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,

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.

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
