Re: replace width/height values in youtube script

[Mike Little]

ok, i have made an attempt at converting a php function. unfortunately it does 
not quite work. i think i am close ??

cffunction name=resize_markup access=public returntype=string 
output=false
cfargument name=markup type=string required=yes
cfargument name=width type=numeric required=false
cfargument name=height type=numeric required=false

cfset var patterns = arrayNew(1)
cfset var replacements = arrayNew(1)

cfif isDefined(arguments.width)

cfscript
pattern = 'width=([0-9]+)';
arrayAppend(patterns, pattern);

pattern = 'width:([0-9]+)';
arrayAppend(patterns, pattern);

replacement = 'width='  arguments.width  '';
arrayAppend(replacements, replacement);

replacement = 'width:'  arguments.width;
arrayAppend(replacements, replacement);
/cfscript 

/cfif

cfif isDefined(arguments.height)

cfscript
pattern = 'height=([0-9]+)';
arrayAppend(patterns, pattern);

pattern = 'height:([0-9]+)';
arrayAppend(patterns, pattern);

replacement = 'height='  arguments.height  
'';
arrayAppend(replacements, replacement);

replacement = 'height:'  arguments.height;
arrayAppend(replacements, replacement);
/cfscript 

/cfif

cfloop from=1 to=#arrayLen(patterns)# index=idx

cfset new_string = REReplaceNoCase(arguments.markup, 
patterns[idx], replacements[idx], All)

/cfloop

cfreturn new_string /

/cffunction

Re: replace width/height values in youtube script

[Mike Little]

ah i found the prob.

put this at top of function: 

cfset var new_string = arguments.markup

and the rereplace becomes:

cfset new_string = REReplaceNoCase(new_string, '#patterns[idx]#', 
'#replacements[idx]#', 'All')

replace width/height values in youtube script

[Mike Little]

hey guys,

developing an app that the user inputs the embed script from a youtube video. 
what i want however, is for all width= and height= attributes to be 
replaced with custom values that fit our site layout.

just a little lost as how to do this with a regular expression.

any help will be greatly appreciated.

mike
