Hi, I still got problems after I changed my code according to your suggestion. Here is the detail describtion of my code: In registration form, I have a table which contain a field usr_email (<tr> <td width="40%" align="right">Email Address </td> <td width="60%"><input type="text" name="usr_email" size="20"></td> </tr>) This form takes an action in which I have following lines: <dtml-if search_membership> <p>Your email address has been used. </p> <dtml-else> <dtml-call personinfo_insert> <h2>Welcome <dtml-var name="usr_fname">! You became a new user.</h2> </dtml-if> where "search_membership" is an ZSQL method (select usr_email from personinfo where usr_email = <dtml-var name="usr_email">) and "personinfo_insert" is a ZSQL method which insert the data to the table("personinfo") My idea is first checking if usr_email is in the table, if so, do not insert, otherwise insert. If I just use <dtml-call personinfo_insert>, everything is fine. However, when I added the <dtml-if> as above, I got the following error: Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: usr_email Could you help me out? Thanks! Sa
Hi,
Hi, I stuck on a problem: I am creating a registration form. I need to check if the person info has already in database. I created a Z SQL method which I used "select usr_email from info(table name) where usr_email = <dtml-sqlvar usr_email type=string>" I want to call this method from my dtml method and see if it returns "null". But I'm not sure how to implement this. In Java, it has ResultSet which I can
let's say, you called your ZSQL-method "getThisAddress"
then you can do something like this:
<dtml-if getThisAddress> You are already in the database </dtml-if>
