Hi,
I have a drop-down list which is dynamically populated from a database lookup table using the <dtml-in> structure to iterate through the list of rows and add an <OPTION> to the drop-down for each row in the table.
like so:
<select name="Purpose"> <dtml-in sqlLookupResearchPurpose>
<option value="<dtml-var "RESEARCH_PURPOSE">"> <dtml- var "RESEARCH_PURPOSE"> </option>
</dtml-in> </select>
I want to be able to add the SELECTED HTML attribute to a specific option which is determined only at runtime. Basically if the current value of research_purpose field equals the value of the purpose variable I want to insert the select attribute at this point.
<dtml-if expr="<dtml-var "RESEARCH_PURPOSE"> == <dtml-var "PURPOSE">"> SELECTED </dtml-if>
jou cant nest <dtml-...> tags
However, I get a syntax error. How do you usually test the condition when 2 variable are equal?
Putting the code together:
<select name="Purpose"> <dtml-in sqlLookupResearchPurpose> <option value="<dtml-var "RESEARCH_PURPOSE">"
<dtml−if expr="<dtml-var "RESEARCH_PURPOSE"> == <dtml-var "PURPOSE">"> SELECTED </dtml−if>
> <dtml-var "RESEARCH_PURPOSE"> </option> </dtml-in>
</select>
If anyone could show me how this is normally done or point me in the direction of any tutorials/how-tos etc. it would be appreciated..
<select name="Purpose"> <dtml-let res=sqlLookupResearchPurpose> <dtml-in res> <option value="<dtml-var "RESEARCH_PURPOSE">" <dtml-if "RESEARCH_PURPOSE==PURPOSE">SELECTED</dtml-if>
<dtml-var "RESEARCH_PURPOSE"> </option> </dtml-in res> </dtml-let res> </select>
