Handling multiple selects.

mrbaseball34

I have a multiple select defined like this:

  <select name="division" size="5" multiple="true">
    <option value="all">All</option>
    <option value="austin">Austin</option>
    <option value="capitol">CAP</option>
    <option value="lonestar">LS</option>
    <option value="mabl">MABL</option>
  </select>

Now how would I handle that in this code:

if ($division == '') {
$division = 'all';
}
switch ($division) {
  case "austin":
    buildaustin($db);
    break;
  case "capitol":
    buildcapitol($db);
    break;
  case "lonestar":
    buildlonestar($db);
    break;
  case "mabl":
    buildmabl($db);
    break; 
  case "all":
    buildaustin($db);
    buildcapitol($db);
    buildlonestar($db);
    buildmabl($db);
    break;
}

I only want to do the "all" if it is the only one selected but do all
others if more than one is selected.

assuming you have register_globals turned on, it looks like your code will do exactly what you want. what is the problem?

You could utilize switch overflow (not sure if that's the correct terminology but you'll see what I mean)

switch ($division) {
  case "austin":
    buildaustin($db);
    break;
  case "capitol":
    buildcapitol($db);
    break;
  case "lonestar":
    buildlonestar($db);
    break;
  case "mabl":
    buildmabl($db);
    break;
  //because there's no break after the case "all"
  //it will "overflow" into the default 
  case "all":
  default:
    buildaustin($db);
    buildcapitol($db);
    buildlonestar($db);
    buildmabl($db);
    break;
}

<select name="division[]" size="5" multiple="true">
    <option value="all">All</option>
    <option value="austin">Austin</option>
    <option value="capitol">CAP</option>
    <option value="lonestar">LS</option>
    <option value="mabl">MABL</option>
  </select>

Note the change of division to array...

$i=0;
$division = $_POST['division'];   // OR GET if u are using that
foreach($division as $div)
 if($div=="all")
   $i = 1;
if($i==1)
{
    buildaustin($db); 
    buildcapitol($db); 
    buildlonestar($db); 
    buildmabl($db); 
}else
{
foreach($division as $div)
{

switch ($div) { 
  case "austin": 
    buildaustin($db); 
    break; 
  case "capitol": 
    buildcapitol($db); 
    break; 
  case "lonestar": 
    buildlonestar($db); 
    break; 
  case "mabl": 
    buildmabl($db); 
    break; 
  default: 
     break; 
}
}

This should work from wat I understood from your post... I guess u can make this logic better 😉

Good Luck

No, it won't. It won't iterate though the choices if I have more than one selected.

tommynanda,

That is very close, but this test page shows each division that
is seleced the same number of selected divisions.

For instance, if I select Austin and MABL, it shows:
{two options selected}
austin
mabl
austin
mabl

If I select Austin Capitol and LS, it shows:
{three options selected}
austin
capitol
lonestar
austin
capitol
lonestar
austin
capitol
lonestar

How would I keep that from happening?

<?php
$i=0; 
$division = $_POST['division'];
foreach($division as $div) 
{
  if($div=="all") 
  { 
   $i = 1; 
  }
  if($i==1) 
  { 
    echo "All<br>";  

  } else 
  { 
    foreach($division as $div) 
    { 
      switch ($div) {  

      case "austin":  

        echo $div."<br>";  

        break;  

      case "capitol":  

        echo $div."<br>";  

        break;  

      case "lonestar":  

        echo $div."<br>";  

        break;  

      case "mabl":  

        echo $div."<br>";  

        break;  

      default:  

         break;  

      } 
    $div = '';
    }
  }
}

There is slight difference from the code I posted and u r using rite now... U have an extra { after 1st for each.. just remove that or close that with another } rite after if condition something like this

<?php 
$i=0;  

$division = $_POST['division']; 
foreach($division as $div)  

{ 
  if($div=="all")  

  {  

   $i = 1;  

  } 
}
  if($i==1)  

  {  

    echo "All<br>";   

  } else  

  {  

    foreach($division as $div)  

    {  

      switch ($div) {   

      case "austin":   

        echo $div."<br>";   

        break;   

      case "capitol":   

        echo $div."<br>";   

        break;   

      case "lonestar":   

        echo $div."<br>";   

        break;   

      case "mabl":   

        echo $div."<br>";   

        break;   

      default:   

         break;   

      }  

    $div = ''; 
    } 
  } 
} 
?> 
<html> 
<head> 
</head> 
<body> 
  <form name="baseform" action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post"> 
    <select name="division[]" size="5" multiple="true"> 
      <option value="all">All</option> 
      <option value="austin">Austin</option> 
      <option value="capitol">CAP</option> 
      <option value="lonestar">LS</option> 
      <option value="mabl">MABL</option> 
    </select> 
    <input type="submit" name="Submit" value="Build Ticker Files">       

  </form> 
</body> 
</html>
