Question

I have a little problem with a selectbox that have to have some marked options from a URL parameter.

I have an URL that can look like this

index.php?page=edit&lid=4&recs=1,4,7&hl=Test&lhash=7c2cd87dad07ac99a00e92041a5d6a38

Where I want to use 1,4,7 from the recs parameter to mark the mailgroups with ID 1, 4 and 7 in my selectbox like

<select name="groups" multiple="multiple">
<option value="1" selected="selected">Group 1</option>
<option value="2">Group 2</option>
<option value="3">Group 3</option>
<option value="4" selected="selected">Group 4</option>
<option value="5">Group 5</option>
<option value="6">Group 6</option>
<option value="7" selected="selected">Group 7</option>
<option value="8">Group 8</option>
</select>

I tried to use this to make a variable with the selected=”selected” value

$recis = explode(",", $_GET["recs"]);
foreach($recis as $rec) {
   if($row["mailgroup_id"] == $rec) {
      $sel = 'selected="selected"';
   } else {
      $sel = '';
   }
}

And then

<option value="'. $row["mailgroup_id"] .'" '. $sel .'>'. $row["mailgroup_name"] .' - '. $row["country"] .'</option>

But that doesn’t seem to work as all groups become marked

Answer 1

why don’t you try loop on mailgroup_id record set

$recis = explode(",", $_GET["recs"]);

while($row=mysql_fetch_array($rs))
{
   if( in_array($row["mailgroup_id"], $recis)) 
   {  
      $sel = 'selected="selected"';
   }
   else 
   {
      $sel = '';
   }
   // Option Code
}

Option Code

<option value="'. $row["mailgroup_id"] .'" '. $sel .'>'. $row["mailgroup_name"] .' - '. $row["country"] .'</option>
