make a foreach select menu form sticky - php

Question

I want it so that when people make a selection in my form, the selection they made stays after the form is submitted, or if there was an error in the form, the submitted fields still display their choices. I have tried a lot of things and can't get it to work. I looked for about 30 minutes on Stackoverflow and can't find an answer to this.
<form action="article_rating.php" method="post" class="formbox2"><table class="borderie" width="100%" align="center">
<?php
$ratingarray = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 'Make a Selection');
?>
<p><tr><td align="left"><label for="readable" class="label">Readability Factor- Indicate if you feel this is article is easily readable</label></td><td align="right"><select name="readable">
<?php
foreach($ratingarray as $value){
echo '<option value="'.$value .'"';
echo ' selected="selected"';
echo '>' . $value . '</option>';
}
?>
</select>
</td></tr></p>
<p><tr><td align="left"><label for="originality" class="label">Originality Factor- Indicate how original you feel this article is.</label></td><td align="right"><select name="originality">
<?php
foreach($ratingarray as $value){
echo '<option value="'.$value .'"';
echo ' selected="selected"';
echo '>' . $value . '</option>';
}
?>
</select></td></tr></table></form>

Answer 1

Don't echo selected="selected" for every option. Use an if condition to see if a value for each field was provided previously, and only echo selected if the value in the current iteration of the loop matches.
Example (assumes you're posting to the same page):
// In your loop
if (isset($_POST['readable'] && $_POST['readable'] == $value) {
// echo selected
}
