save multiple id, in a field.

[agxFalcon]

Hello guys!

So i have this code:

$genre_list = array(1 => "Action", 2 => "Adventure", 3 => "Comedy", 4 => "Dementia", 5 => "Demons", 6 => "Drama", 7 => "Fantasy", 8 => "Horror");
 
<select name='genre' multiple='multiple' class='multiple' size='8'>
foreach ($genre_list as $genre_id=>$genre_name) {
 <option value='".$genre_id."'>$genre_name</option>
}
 </select>

The thing is, that is saving just the last selected genre_name, how do i fix this problem ?

you can only select 1 value from a select list
you can use some javascript to allow multiple selections
or use checkboxes instead

you can only select 1 value from a select list

Oops! :-)

multiple='multiple'

The trick is with PHP, you need to add [] by the name so it's an array.

name="genre[]"

Tested and working, slight changes because I prefer double-quotes on output HTML attributes . . . matter of preference.

<?php 
header("content-type:text/html"); 
$genre_list = array( 
1 => "Action",  
2 => "Adventure",  
3 => "Comedy",  
4 => "Dementia",  
5 => "Demons",  
6 => "Drama",  
7 => "Fantasy",  
8 => "Horror" 
); 
if (isset($_POST['genre'])) { 
  $genres = $_POST['genre']; 
  foreach ($genres as $g){  
   $form .= "<p>You selected " . $genre_list[$g] . ", key $g</p>";  
  }; 
} 
else { 
 $form = ' 
  <form method="post" action="multiple-selects.php"> 
  <select name="genre[]" multiple="multiple" class="multiple" size="8"> 
 '; 
 foreach ($genre_list as $genre_id=>$genre_name) { 
   $form .= '<option value="'.$genre_id.'">'.$genre_name.'</option>'; 
 } 
 $form .= ' 
  </select>  
  <input type="submit" value="Test It"> 
  </form> 
 '; 
} 
echo $form; 
?>
