Defining selected option of html form in PHP - php

Question

I have a simple html form with select element. To define which option is selected, I add selected as
<option value="10" <?php if($value == '10') {echo 'selected="selected"';}?>>10</option>
<option value="20" <?php if($value == '20') {echo 'selected="selected"';}?>>20</option>
<option value="50" <?php if($value == '50') {echo 'selected="selected"';}?>>50</option>
$value is a variable which comes from PHP codes. This methods seems to be very simple and naive. Is it the best way to do so?

Answer 1

$options = array(10,20,50);
foreach($options as $option) {
$selected = ($value == $option) ? ' selected="selected"' : '';
echo '<option value="' . $option . '"' . $selected . '>' . $option . '</option>';
}

Answer 2

Not a bad way to do it. But why not create the entire thing using programmatic approach (i.e., generate the code using a PHP loop through an array):
$items = array(10, 20, 50);
for ($i = 0; $i < count($items); $i ++) {
echo("<option value='" . $items[$i] . "'");
if ($items[$i] === $value) {
echo(" selected='selected'");
}
echo(">" . $items[$i] . "</option>");
}

Answer 3

Something along the lines of the below should work:
<?
$values = array(10, 20, 30);
foreach ($values as $val) {
?>
<option value="<?=$val?>" <?=($value==$val ? "SELECTED" : "")?>><?=$val?></option>
<?
}
?>

Answer 4

Keep your values in an array and loop over it to generate the HTML. Then you don't need to repeat yourself.

Answer 5

<?php foreach($list as $key => $value): ?>
<option value=<?php echo $value ?> <?php echo $value == $selected? 'selected' : '' ?> ><?php echo $value ?></option>
<?php endforeach ?>
Hope you get the idea.

Answer 6

This is the like i do it:
<?
$values = array(10,20,30,......);
$value = XXX;
echo "<select name='somename'>";
foreach($values as $v)
{
if($v == $value)
{
echo "<option value='$v' 'selected'>$v </option>";
}
else
{
echo "<option value='$v'>$v </ option> ";
}
}
echo "</select>";
?>
