Hi and sorry for spamming you with questions,

while working with items and newsletter templates I have a question:

Is there a tag to determing how many letters you wanna display from them the item/list.

Example:

I'm using an item for people to add content to a newsletter - creating headlines text, images etc. However, the design of the newsletter will be ruined and pushed around, if somebody pasted 5-600 words in an item used for the headline. Therefor, it would be great, if I in some way could define and controle the amount of letters allowed in that item, either by controlling how many letters will be displayed in the document or by giving the item a max value.

Regards

Martin

Hi Martin

In your template, you can do 2 things:

You can use the tag.Remove(100) tag extension method in html templates - i.e  to limit to 100 characters, see http://templates.dynamicweb.com/TemplateTags/Dynamicweb-template-tags/General-tags/Tag-extensions.aspx
Use Razor and make a function to pad the text to a surden max length

You can also limit the allowed amount of characters to type in the admin using the validation field on the item field definition and use a regular expression that limits the amount of characters, i.e. like:

/^[a-zA-Z0-9]{0,10}$/

See http://manual.dynamicweb-cms.com/Dynamicweb-On-line-Manual/Items/Item-fields.aspx

Hope this helps.

Hi Nicolai,

I have the same issue - I need no more than 155 chars and have tried to add the regex below to the textfield in an item. Every time I try to save it I get an error (as if there were more than 155 chars, which there is not). Am I missing something?

^[\d\D]{0,155}$

Hi Sten,

You've found a bug (#15760). The regular expression used for validation in JavaScript is not escaped correctly.

More specifically, the backslashes are not escaped meaning that the expression ^[\d\D]{0,155}$ will only match strings consisting solely of the characters d and D …

Thanks for helping us find this bug.

Best regards,
Mikkel
