Converting an array to an xhtml select list

I have an array given as:

$my_fontSizes = array("" => "100% Default", 
                      "150%" => "150% of default", 
                      "80%" => "80% of default" 
                );

When I turn this into a select list, how do I specify that the "value" o开发者_Go百科f the option is what's on the left side of the => sign and the "text label" is what's on the right?

Example, here's what I'm using now, but the element on the right side of the => is being set as both the value and the label:

<select name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php foreach ($value['options'] as $option) { ?>
    <option<?php if ( get_option( $value['id'] ) == $option) { echo ' selected="selected"'; } ?> value='<?php echo $option; ?>'><?php echo $option; ?></option><?php } ?>
</select>

<?php
foreach ($array as $key => $value)
?>

You want to use a slightly different form of foreach

foreach($array as $key=>$value)

Using this, you are able to grab both the key (left side) and the value (right side) for each option.

First, don't mix your PHP and XHTML like that. It's messy and hard to maintain.

Second, note that you're printing $option as both the name and the value. Here's what I would do:

$my_fontSizes = array(
                    ""     => "100% Default", 
                    "150%" => "150% of default", 
                    "80%"  => "80% of default");

$HTML = sprintf('<select name="%s" id="%s">', $Value['id'], $Value['id']);

foreach ($my_fontSizes as $Key => $Value)
{
    $Selected = ($OtherValue == $Value) ? 'selected="selected"' : '';
    $HTML .= sprintf('<option %s value="%s">%s</option>', $Selected, $Key, $Value);
}

$HTML .= '</select>';

echo $HTML;

You want to use a slightly different foreach loop:

foreach($array as $key=>$value)

So your code would be:

<select name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php foreach ($value['options'] as $value $option) { ?>
    <option<?php if ( get_option( $value['id'] ) == $option) { echo ' selected="selected"'; } ?> value='<?php echo $value; ?>'><?php echo $option; ?></option><?php } ?>
</select>

Your code is missing a variable named $value and "100% Default" will need a value (like 0 OR null , just to fill the space) but your can loop through your array and get the value and option text like so:

<select>
<?php
foreach($my_fontSizes as $value => $key)
{
?>
<option value="<?php echo $value; ?>"><?php echo $key; ?></option>
<?php
}
?>
</select>

<select name="<?=$value['id']?>" id="<?=$value['id']?>">
<?php foreach ($value['options'] as $value=>$option) { ?>
    <option<?=(get_option( $value['id'] ) == $value ? ' selected="selected"' : '')?> value='<?=$value?>'><?=$option?></option>
<?php } ?>
</select>

And a slightly more cleaned up markup (but the same answer as everyone else)

You would use array_keys() and go through the keys to print the option values.
