<cfset post =paragraphformat(post)>???

[peter11]

I am trying to allow for users to create <br> when they hit the enter key while typing in a Textarea.

I tried the following:

<cfset post=paragraphformat(post)>
This returned an Cold fusion Error on post=paragraphformat(post)

<cfset post=relacelist(post,&quot;#chr(13)#, <, >, #chr(34)#, #chr(39)#, #chr(35)#, #chr(38)#, #chr(47)#&quot;, , &quot;<br>, &lt;, &gt;, &quot;, &acute;, &#35;, &#38;, &#47;&quot;, &quot;all&quot;>
This returned multiple errors.

Does anyone know what the problem is with these?

Thanks

first, you have few typos in there;
second, when you want to have double quote as a part of the string, you have to escape them by repeating them (set i = &quot;&quot;&quot; wil give you error; set i = &quot;&quot;&quot;&quot; where i is &quot;
third, you can't scope ReplaceList() function with &quot;one&quot; or &quot;all&quot; - it does not support that; you might want to use loop to check for characters you want to replace and then if char is found, use Replace() which you CAN scope with &quot;all&quot;

I haven't test the following code, but this should give you an idea as what I am suggesting:

<cfset replaceList = &quot;#chr(13)#, <, >, #chr(34)#, #chr(39)#, #chr(35)#, #chr(38)#, #chr(47)#&quot;>
<cfset replaceChars = &quot;<br>, <, >, &quot;&quot;, ``, #, &, /&quot;>

<cfset counter = 1>
<cfloop index=&quot;replaceCounter&quot; list=&quot;replaceList&quot; delimiters=&quot;,&quot;>
<cfset char = Find(replaceCounter, post)>
<cfif char GT 0>
<cfset post = Replace(post, replaceCounter, ListGetAt(), &quot;all&quot>
</cfif>
<cfset counter = counter + 1>

Sylvano,
Do you know where I could get a book or more information on this topic?

I tried the following code and it got hung up at the comma after the #after ``, on the third line of code.

I removed that section of code from the second and third line of code and the code then hung up at <cfset char = Find(replaceCounter, post)>, on the eigth line of code.

The worst part is I really do not understand this code. Can anyone solve this problem or tell me where I can reasearch this topic.

<cfset replaceList = &quot;#chr(13)#, <, >, #chr(34)#, #chr(39)#, #chr(35)#, #chr(38)#, #chr(47)#&quot;>
<cfset replaceChars = &quot;<br>, <, >, &quot;&quot;, ``, #, &, /&quot;>

<cfset counter = 1>
<cfloop index=&quot;replaceCounter&quot; list=&quot;replaceList&quot; delimiters=&quot;,&quot;>
<cfset char = Find(replaceCounter, post)>
<cfif char GT 0>
<cfset post = Replace(post, replaceCounter, ListGetAt(), &quot;all&quot>
</cfif>
<cfset counter = counter + 1>
</cfloop>

I don't see why you'd get an error with. What is the error?
<CFSET post = ParagraphFormat(post)>

Here the fixes to the other code.
<CFSET post = ReplaceList(post, &quot;#chr(10)#, <, >, #chr(34)#, #chr(39)#, #chr(35)#, #chr(38)#, #chr(47)#&quot;, &quot;<br>, <, >, &quot;&quot;, ´, ##, &, /&quot;)>


What is it you are exactly trying to accomplish here? - tleish

go to:

or use keyword &quot;escape&quot; to search exchange; you'll get several free tags you can use here Sylvano

Sylvano -Thanks

Tleish -I want the database to store the information the user enters and reproduce it exactly as it was entered, with the same charaters, carriage returns. And to display html tags, not apply the tags to the other text they entered.

[COLOR=666666]/* Format spaces, tabs, and returns instead of this step
you could simply put the text in <PRE></PRE> tags and
it will display the proper format of tabs, spaces,
and returns which makes cleaner source

SPACES: There's no need to replace every space with a
no-break-space, just every 2 Replace 2 spaces
&quot;#Chr(32)##Chr(32)#&quot; with 2 no-break-space
&quot;&nbsp;&nbsp;&quot;

TABS: To force tabs we need to replace every tab
with 8 no-break-space Replace 1 tab &quot;#Chr(9)#&quot;
with 8 no-break-space &quot;#RepeatString('&nbsp;', 8)#&quot;

RETURNS: To force HTML returns we replace all carriage
returns #Chr(10)# with <BR> and to format the
code correctly we still keep our carriage returns
#Chr(10)#, otherwise it becomes one big string.
Replace 1 return &quot;#Chr(10)#&quot; with &quot;<BR>#Chr(10)#&quot;

That last post should have & nbsp; (withouth the space between &quot;&&quot; and &quot;nbsp;&quot instead of spaces, but cftips is interpreting it as spaces


post2 = ReplaceList(post1, &quot;#Chr(32)##Chr(32)#,#Chr(9)#,#Chr(10)#&quot;, &quot;& nbsp;& nbsp;,#RepeatString('& nbsp;', 8)#,<BR>#Chr(10)#&quot; - tleish

tleish -
Thanks.
That worked perfect, but I do not really understand how it works.
Can you tell me where I can learn more about this. Are there any textbooks or books I can get?

Thanks for the great help

Peter
