SIZE OF A TEMPLATE VARIABLE

Hello there!
does anybody know how to limit the size (characters to enter) of a template variable??

plllleeeease help, I can’t find the answer

I believe the TV values for strings are limited to 65,535 characters in PHP5. Less if they contain multibyte characters.

What do you mean by size?

Are you referring to the content of a TV or its name. A richtext editor would allow much more room for the content than a simple text field would. Can you be a bit more specific and maybe tell us why need the info?

Yeah, I don’t think it’s possible yet

Hello!
Thanks for your answers, what I am looking for is exactly that, I need to be able to limit the size of a tv, so that I can display it in a string length defined area.

I came up with the solution of having a substring snippet, so I can always cut the output string if needed. I worked for a bit, I have realized that the snippet gets rid of quotation marks. I am using this solution to format the title of various news items, they need quotation marks, so again, I am in the same place... any suggestions guys? please :’(

You could use a plugin to add some javascript to do this; since it’s from the Manager and with relatively trusted users I don’t imagine the risk of someone hacking the page would be an issue.

I’m presuming you’re using a text input type. If so, the input element for the TV will have an id attribute
like id="tvMyTV". So you could have your javascript add the size and maxlenght attributes to that input element. Something like this: http://www.brighthub.com/internet/web-development/articles/9231.aspx

This definitely will require a custom plugin to be written, leveraging Javascript, or manually hacking the associated action page if it applies across the board. (Plugin is the best option)
