Foreach php function inside HTML select options

Question

Im a newbie to this forum and have just started coding in php. Need some help. I have the following code

Answer 1

You mean you need the value what you have used to display it. Then, Change to :

<option value="<?php echo $value['profile']; ?>">
    <?php echo $value['profile']; ?>
</option> 

Answer 2

Give

<option value="<?php echo $value['profile']; ?>"><?php echo $value['profile']; ?></option> 

instead of

<option value="<?php echo $key; ?>"><?php echo $value['profile']; ?></option> 

Answer 3

It will obviously echo the key, as you assigned the value of options as $key if you need the options in the $_POST['pty_select'] use this:

 <select name="pty_select" > 
<?php foreach($results_array as $key => $value){ ?>
                <option value="<?php echo $value['profile'];?>"><?php echo $value['profile'];     ?></option> 
<?php } ?>
    </select>

Answer 4

if (isset($_POST['Submit'])) {
echo "<pre>"; echo ($_POST['pty_select']); echo "</pre>"; } ?> 

Change it to something like

if(isset($_POST['Submit'])) {
    echo $results_array[$_POST['pty_select']]['profile'];
}

Or alternatively use profile option value.

Answer 5

And now let's go to ideal world :)

Build data pairs database_id => name for options:

$q = "SELECT pty.id, pty.pty_profile_name AS profile FROM pty, users 
      WHERE users.username = 'testaccount'";
$r = mysqli_query($dbc, $q);

$values = array();
while($r = mysqli_fetch_row($r)) {
    $values[$r[0]] = $r[1];
}

Never use @ when working with database, why do you want to suppress errors instead of preventing/handling them?

Now you have real database IDs and respective values (in general, using unique IDs are better... if nothing else they have greater entropy - more efficient search). And sice displaying select box is really common in webs, lets:

function selectbox( $values = array(), $attributes = array(), $selected_value = null)
{
    // Header
    echo '<select';
    foreach( $attributes as $key => $val){
        echo ' ' . htmlspecialchars($key) . '="' . htmlspecialchars( $val) . '"';
    }
    echo '>';

    // Values
    foreach( $values as $key => $val){
        echo '<option value="' . htmlspecialchars( $key) .'"';
        if( $key === $selected_value){
            echo ' selected="selected"';
        }
        echo '>' . htmlspecialchars( $val) . '</option>';
    }
    echo '</select>';
}

And now usage :)

<form method="post" action="foreach2.php">
<label for="Property Select" class="title">Select Property</label>  
    <?php selectbox( $values, array( 'name' => 'pty_select')); ?>
    <input type="submit" name="Submit" />
</form>

And what to do with it then?

$id = (int)(isset( $_POST['pty_select']) ? $_POST['pty_select'] : 0);
$name = null;
if( $id && isset( $values[$id])){
    $name = $values[$id];
}
