Greyed out 'Populate List From Array'

Greyed out 'Populate List From Array'

I've been following the .pdf help guide featuring step by step instructions for the dynamic drop-downs, however i have stalled at step 4 on page 8.

I have two drop downs; a parent and child.

I have prepared the parent list as per page 6 and have created a dynamic array using the server behaviour WA Dynamic Drop-downs option.

Then with the parent still selected, I attempted to select 'Populate List From Array' from the WA Dynamic Array Drop-downs, but its greyed out so I can select.

I have to say, the instructions are not at all clear as they appear to combine instructions for both lists and menus, so its difficult to pull out the important steps for the drop down menu functionality.

Screen-grab attached illustrating issue.

Ideas welcome.

Thanks, Paul

at the top of the behaviors panel, what tag does it show as being selected? See the attached screen shot for an illustration of what I mean.

If you are still having a problem, please send a copy of your page.

hmmm, seams to be an issue with templartes, I'll log this as a bug.


for a workaround, move the create dynamic array code that is at lines 102 - 148:;


php:
<?php

if ($row_rsTowns)     {
  echo 
"<SC" "RIPT>\n";
  echo 
"var WAJA = new Array();\n";

  
$oldmainid 0;
  
$newmainid $row_rsTowns["Town_CountyID"];
  if (
$oldmainid == $newmainid)    {
    
$oldmainid "";
  }
  
$n 0;
  while (
$row_rsTowns)     {
    if (
$oldmainid != $newmainid)     {
      echo 
"WAJA[".$n."] = new Array();\n";
      echo 
"WAJA[".$n."][0] = '".WA_DD_Replace($newmainid)."';\n";
      
$m 1;
    }

    echo 
"WAJA[".$n."][".$m."] = new Array();\n";
    echo 
"WAJA[".$n."][".$m."][0] = "."'".WA_DD_Replace($row_rsTowns["Town_IDX"])."'".";\n";
    echo 
"WAJA[".$n."][".$m."][1] = "."'".WA_DD_Replace($row_rsTowns["Town_Name"])."'".";\n";

    
$m++;
    if (
$oldmainid == 0)      {
      
$oldmainid $newmainid;
    }
    
$oldmainid $newmainid;
    
$row_rsTowns mysql_fetch_assoc($rsTowns);
    if (
$row_rsTowns)     {
      
$newmainid $row_rsTowns["Town_CountyID"];
    }
    if (
$oldmainid != $newmainid)     {
      
$n++;
    }
  }

  echo 
"var rsTowns_WAJA = WAJA;\n";
  echo 
"WAJA = null;\n";
  echo 
"</SC" "RIPT>\n";
}
function 
WA_DD_Replace($startStr)  {
  
$startStr str_replace("'""|WA|"$startStr);
  
$startStr str_replace("\\""\\\\"$startStr);
  
$startStr preg_replace("/[\r\n]{1,}/"" "$startStr);
  return 
$startStr;
}
?>



to line 96 so it is just before the doctype tag so you can apply the populate list from array behavior. Move it back to line 102 after the populate list from array behavior is applied.

Ok, so that workaround was successful.

The bug does seem to be connected with CS5 templates .dwt or dwt.php

The wizard works fine on plain .php pages. Would be interested to see if this can be fixed in next update.

Just realised that my child value is not retrieving from mysql.
Both parent and child are saving to their respecitive values to my DB, but only parent is retrieving the value.

Here is code for Child

<select name="mem_town" id="mem_town">
<option value="" <?php if (!(strcmp("", (str_replace('"', '&quot;', $row_WAATKmembertbl['mem_town']))))) {echo "selected=\"selected\"";} ?>>Select town</option>
<?php
do {
?>
<option value="<?php echo $row_rsTowns['Town_IDX']?>"<?php if (!(strcmp($row_rsTowns['Town_IDX'], (str_replace('"', '&quot;', $row_WAATKmembertbl['mem_town']))))) {echo "selected=\"selected\"";} ?>><?php echo $row_rsTowns['Town_Name']?></option>
<?php
} while ($row_rsTowns = mysql_fetch_assoc($rsTowns));
$rows = mysql_num_rows($rsTowns);
if($rows > 0) {
mysql_data_seek($rsTowns, 0);
$row_rsTowns = mysql_fetch_assoc($rsTowns);
}
?>
</select>

Am I missing something here?

is this on an update page then?
Please provide more details.

This is on an update page.

When loaded, both drop-down dependencies populate ok
Parent and child data saves to sql db.

When user returns to update, only parent value is retrieved and displays.
The child drop-down is empty

Filer attached.

on an update page, you need to apply the Set Selected in list behavior for the parent list, and the populate list from array behavior for the child list to the body onlaod tag.

this can be problematic with a template though. with a template, you will need to apply the behaviors to another tag, then cut the code for the behavior and place it in a script tag at the lowest part of your page.
