Wordpress get posts as a function - php

Question

Hi I'm trying to create a function to show a list of posts in my admin menu of wordpress but because I'm calling the function a few times on the same page I needed to add some extra statements but it breaks the output and I don't know why
Here is my current code that outputs the basics:
function test() {
// The Query
query_posts( array ('posts_per_page' => -1 ) );
// The Loop
while ( have_posts() ) : the_post();
?>
<option value="<?php the_permalink() ?>"><?php the_title(); ?></option>
<?php endwhile;
// Reset Query
wp_reset_query();
}
Output code:
<select>
<?php test(); ?>
</select>
Returned Output:
<select>
<option value="http://website/posttitle1">POST TITLE 1</option>
<option value="http://website/posttitle2">POST TITLE 2</option>
<option value="http://website/posttitle3">POST TITLE 3</option>
</select>
But I need to add a select option on like this:
function test($select) {
// The Query
query_posts( array ('posts_per_page' => -1 ) );
// The Loop
while ( have_posts() ) : the_post();
if ($select == the_permalink()) { $selected = " selected"; }
?>
<option value="<?php the_permalink() ?>"><?php the_title(); ?></option><?php echo "\n"; ?>
<?php endwhile;
// Reset Query
wp_reset_query();
}
Output code:
<select>
<?php test("..GET Permalink from Database.."); ?>
</select>
But then this is my output:
<select>
http://website/posttitle1<option value="http://website/posttitle1">POST TITLE 1</option>
http://website/posttitle2<option value="http://website/posttitle2">POST TITLE 2</option>
http://website/posttitle3<option value="http://website/posttitle2">POST TITLE 3</option>
</select>
I dont understand?

Answer 1

the_permalink() print the value and get_permalink() returns the value.
Try this.
Change the following line
if($select == the_permalink()) { $selected = " selected"; }
to
if ($select == get_permalink()) { $selected = " selected"; }
And this line to
<option value="<?php the_permalink() ?>"><?php the_title(); ?></option><?php echo "\n"; ?>
this
<option value="<?php echo get_permalink() ?>"><?php echo get_the_title(); ?></option><?php echo "\n"; ?>
