test for alphanumeric plus a few characters

[kayakbabe]

I must be brain dead today becuase I think I've done this before...
I want to test if a variable contains alphanumeric plus period, hyphen and underscore characters

I think toolbelt will do it but I can't figure out the syntax.

I have tried this first
<mvt:item name="ry_toolbelt" param="Assign|g.ke_test|isAlphaNumPlus(l.all_setti ngs:item:image,'.-_')" />
Then I tried this to test only for a period
<mvt:item name="ry_toolbelt" param="Assign|g.ke_test|isAlphaNumPlus(l.all_setti ngs:item:image,asciichar(46))" />

toolbelt is supposed to return a 1 (passed the tests) or a 0 (doesn't pass the test)

anyway I"m just not getting the syntax for it and I do have the current toolbelt.
Can some of you peeps help out (I can't find any example in the forum when I search for isAlphaNumPlus)?

Or maybe there is a toolkit command to test for alphanumberic plus a few characters?

Re: test for alphanumeric plus a few characters

I think I figured it out..

<mvt:item name="ry_toolbelt" param="assign|g.IsValid|isAlphaNumPlus(l.all_settings:item:image,'./-_')" />

but that's not what I want
because it is still letting spaces and parenthesis through

I need to test for 0-9a-zA-Z plus ./-_ characters. if the variable contains anything else then I want a 0 or false answer

Re: test for alphanumeric plus a few characters

here is an inelegant solution which won't catch everything.. but most of what I Was trying to avoid.
The problem is it won't catch any weird characters that I do not explicitly test for.
I KNOW some of my data that is bad has parenthesis, comma, space, brackets and pound signs...
there might be others. and this won't catch them.

<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(l.all_settings:item :image,' ','')" />
<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(g.KE_test,'(','')" />
<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(g.KE_test,')','')" />
<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(g.KE_test,'#','')" />
<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(g.KE_test,'[','')" />
<mvt:item name="ry_toolbelt" param="assign|g.KE_test|glosub(g.KE_test,']','')" />




<mvt:if expr="len(l.settings:item:image) EQ len(g.KE_test)">
OK - contains no bad characters that I tested for
<mvt:else>
BAD - contains at least one of the disallowed characters
</mvt:if>

Guess I"M still looking for a better solution.
