Question

converting string to number tried val(), int() and_integer as suffix

Asked by: gregoryrsmith

Hi,

Is there any way to convert a form value to a number?

I've tried <cfoutput>#Val(FORM.numOfFields)#</cfoutput>
             <cfoutput>#Int(FORM.numOfFields)#</cfoutput>
and CF said that naming the input with a  _integer  suffix would make CF automatically convert string to number, but I got the same error.

Thanks for any help,
Greg

I am confused.  Why do you think it is not a number?

 

by: pinaldavePosted on 2004-11-05 at 14:44:16ID: 12509630

Hi gregoryrsmith,
val() and int() functions if there is no number but only text in the field of numoffileds then it will give you NULL and will not display anything.

The error says this

The value "<cfoutput>3</cfoutput>" cannot be converted to a number

I went to the documentation and searched Google and this site, but the 3 things I've tried (above) still produced the above error.

 

by: pinaldavePosted on 2004-11-05 at 14:49:53ID: 12509667

Hi gregoryrsmith,
 '<cfoutput>3</cfoutput>'
your form value is sending this information...that is incorrect. Check yoru form value...
may be in yoru form where you are submitting the value is like that... value='<cfoutput>numOfFields</cfoutput>'
which is not correct "may be" ...so just check yoru form again.


Regards,
---Pinal

Checked it, maybe you see something I don't (very likely)?

<cfoutput>
  <form action="c_UplThumb.cfm" method="post">
    <input name="numOfFields" type="text" size="5" maxlength="5"><br>
      <input name="folderNumber" type="hidden" value="#FORM.number#">
    <input type="submit" name="Submit" value="OK">
  </form>       
      </cfoutput>

The action page here

<form action="c_UplThumb2.cfm" method="post" enctype="multipart/form-data">
     <cfloop index="i" from="1" to="<cfoutput>FORM.numOfFields#</cfoutput>" step="1">
      <cfset filename = "file" & #i#>
       <input type="File" name="<cfoutput>#variables.filename#</cfoutput>"><br>
      </cfloop>
         <input type="hidden" name="finalFolder"
               value="<cfoutput>#FORM.folderNumber#</cfoutput>

              <input type="Submit" name="upload" value="upload">
 </form>

Thanks,
G

<cfloop index="i" from="1" to="<cfoutput>FORM.numOfFields#</cfoutput>" step="1">
on the action page is incorrect.

SHould be:

<cfloop index="i" from="1" to="#FORM.numOfFields#" step="1">

NO CFOUTPUT inside the cfloop tag

 

by: mrichmonPosted on 2004-11-05 at 15:45:57ID: 12510106

In general you never need cfoutput inside cold fusion tags

Additionally you don't need # signs UNLESS it is inside a quoted string (such as in the case of cfloop)
