How to create a rule "do not show if blank"

How to create a rule "do not show if blank"

We have created a search that in some cases will have fields that are null in our table. We would like the results page to not show the blank fields as spaces. If we have a search for a person that has a "name, address and phone" and the next has just "name and phone" we would like the space for "address" to not show. I assume that we should create a rule somewhere on this page that says "don't show if null" or along those lines. We are fairly new to this function so any assistance would be greatly appreciated.
Thanks

Hi,

This is fairly easy using a bit of PHP. Below is an example of NOT showing a table row if a column is empty.

If want to do the opposite (Only show it if it has a value) then change !="" to ==""

The first is saying show if the column is NOT empty (it HAS a value), the second is Show if the column IS empty (It DOESN'T have a value). This is useful for displaying a "No results found" message.

php:
<?php if ($row_rsRecordset['address']!=""){ ?>

<tr>
<th>Address:</th>
<td><?php echo $row_rsRecordset['address']; ?></td>
</tr>
<?php ?>

You may also want to modify the if statement to check for null in addition to a blank record:

php:
<?php if (($row_rsRecordset['address'] != "") && ($row_rsRecordset['address'] != NULL)){ ?>

did you see my previous reply about adding a check for null to the if statement?

if it is not working, can you send a copy of your page so I can examine the code?

We did read your thread, however would appreciate some enlightening to where this code belongs, we looked at our code (we're novices) and do not see where to alter or change what the WA plugin has created.

I've attached the files for your review,

Thank you very much!

exactly where the code goes depends on where you want to use it.


lets take the detail page as an example.

the code to display the First name is:

php:
<tr>

          <th class="WADADataTableHeader">FirstName:</th>
          <td class="WADADataTableCell"><?php echo($row_WADArick['FirstName']); ?></td>
        </tr>




to suppress the first name row from being created if the first name is empty or null, you add the if statement around it:

php:
<?php if(($row_WADArick['FirstName'] != "" ) && ($row_WADArick['FirstName'] != NULL)) { ?><tr>

          <th class="WADADataTableHeader">FirstName:</th>
          <td class="WADADataTableCell"><?php echo($row_WADArick['FirstName']); ?></td>
        </tr><?php ?>





or if you wish to suppress the last name change:

php:
<tr>

          <th class="WADADataTableHeader">LastName:</th>
          <td class="WADADataTableCell"><?php echo($row_WADArick['LastName']); ?></td>
        </tr>




to:

php:
<?php if(($row_WADArick['LastName'] != "" ) && ($row_WADArick['LastName'] != NULL)) { ?><tr>

          <th class="WADADataTableHeader">LastName:</th>
          <td class="WADADataTableCell"><?php echo($row_WADArick['LastName']); ?></td>
        </tr><?php ?>
