Question

i am using the following multiselect box to take input from users, this then gets posted to my php form which adds it to the database, the problem is, all I am getting added is the first selection, if the user selects more than one field I still only get the first field.

If the user selects lets say internet, drawing,maths I want that to be put into the database, at the moment all that is inserted is internet, or whatever is the first thing selected in the list.

My form looks like this >>

    <form action="../files/addtodb.php" method="post" style="width:800px;">
    <select name="whatisdeviceusedfor[]" size="1" multiple="multiple" id="whatisdeviceusedfor[]">
        <option value="games">Games</option>
        <option value="takingphotos">Taking Photos</option>
        <option value="maths">Maths</option>
        <option value="reading">Reading</option>
        <option value="drawing">Drawing</option>
        <option value="internet">Internet</option>
        <option value="other">Other (enter more info below)</option>
      </select>
      <input type="submit" name="submit" id="submit" value="Submit">
      </form>

The php side looks like this >>

 <?php

 // Implode what is device used for
$usedfor = $_POST['whatisdeviceusedfor'];
$arr = array($usedfor);
$whatisdeviceusedfor = implode(" ",$arr);



// Insert posted data into database
mysql_query("INSERT INTO itsnb_year5questionaire (whatisdeviceusedfor) VALUES   '$whatisdeviceusedfor'") or die(mysql_error()); 

   ?>

Answer 1

you are already getting array by select so you dont need to use $arr = array($usedfor);this again

just try

$usedfor = $_POST['whatisdeviceusedfor'];

$whatisdeviceusedfor = implode(" ",$usedfor);

or

$usedfor = $_POST['whatisdeviceusedfor'];


$strings ='';
foreach ($usedfor as $item){
    $strings .=' '. $item;
}
echo $strings;

and

 <select name="whatisdeviceusedfor[]" size="5" multiple="multiple" id="whatisdeviceusedfor[]">
                                           ^^             
                                           ||change to option you want to select 

i have changed size="5" so it will select now 5 at a time …you have only 1 so it will let only 1 select at a time

result
