Re: [Zope] control of layout in ZPT

13 Jun 2003

      You're trying to call youremail out the scope of where it's defined. In the 
first block the input is within the TD block where youremail is defined. In 
the second block the youremail is called within another TD block outside of 
the TD block where youremail has been defined.

Something else you may want to think about is to stop using tables for 
layout control. CSS offers you significantly more control and is much less 
complex than messing with tables.

for example: borrowing some tips from alistapart.com
...
<tr >
   <th align="left">
    <font size=5><font face="verdana"><b>
     Your Name:
    </b></font></font>
   </th>
   <td tal:define="yourname request/YourName|nothing"><input type="text" 
name="YourName"
       tal:replace="structure python:form.YourName.render(yourname)" />
   </td>
<td tal:define="youremail request/YourEmail|nothing">
      <font size=5><font face="verdana"><b>
     Your Email Address:
    </b></font></font>
   </td>
<td><input type="text" name="YourEmail"
              tal:replace="structure 
python:form.YourEmail.render(youremail)">
   </td>
 </tr>
could become:

     <div class="row">
          <span class="label">Your Name:</span>
          <span class="fld" tal:define="yourname request/YourName|nothing">
                 <input type="text" name="YourName"
                           tal:replace="structure 
python:form.YourName.render(yourname)" />
          </span>
     </div>
     <div class="row">
          <span class="label">Your Email Address:</span>
          <span class="fld" tal:define="yourname request/YourName|nothing">
                 <input type="text" name="YourEmail"
                           tal:replace="structure 
python:form.YourEmail.render(youremail)">
          </span>
     </div>

Then if you define your CSS properly you just line to two divs next to each 
other and you have a continuous row with multiple fields. This also gives 
you a nice clean seperation of structure vs. look and feel and more 
flexibility in future maintenance. Using the FONT tag and Tables for layout 
is for the past and should probably only be used if you absolutely have to 
support IE4/NS4 and below. Fortunately about 98% of the market right now is 
IE5+/NS6/Opera. If you absolutely must stick with using the font tag and 
tables use ONE font tag for formatting <font size="5" face="verdana"> and I 
believe that most user agents automatically bold any text headers for the 
table so there's not much sense in using <B> for those elements.

Hi,
I want to use formulator for designing my forms. However it does not allow 
more than one field to be presented in the same row (a requirement for my 
form).
I am using the example from this URL
http://www.zope.org/Members/beno/HowTo/HowTo/Formulator_With_ZPT
The difficulty I am facing is that the sample code uses:
<tr tal:define="yourname request/YourName|nothing">
   <th align="left">
    <font size=5><font face="verdana"><b>
     Your Name:
    </b></font></font>
   </th>
   <td><input type="text" name="YourName"
       tal:replace="structure python:form.YourName.render(yourname)" />
   </td>
</tr>
for each row. To  make 2 fields appear in the same row, i am trying to do 
this:
<tr >
   <th align="left">
    <font size=5><font face="verdana"><b>
     Your Name:
    </b></font></font>
   </th>
   <td tal:define="yourname request/YourName|nothing"><input type="text" 
name="YourName"
       tal:replace="structure python:form.YourName.render(yourname)" />
   </td>
<td tal:define="youremail request/YourEmail|nothing">
      <font size=5><font face="verdana"><b>
     Your Email Address:
    </b></font></font>
   </td>
<td><input type="text" name="YourEmail"
              tal:replace="structure 
python:form.YourEmail.render(youremail)">
   </td>
 </tr>
However I am getting errors
Error Type NameError
Error Value name 'youremail' is not defined
Can you please help me resolve this.
Thanks
Pradeep
