Need some help with a php if statement

    Hi guys,

    I don’t have the strongest PHP skills and I need a little bit of help with the following.

    Right now I’m using 2 seperate statements like so.

    1.

    <?php if (has_post_thumbnail( $post->ID ) ): ?>
	<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' ); ?>
	<div id="header" style="background-image:url('<?php echo $image[0]; ?>');">
	<?php endif; ?>

    2.

    <?php if (is_front_page() || is_home()) {?>
	<div id="header" class="slide">
	<?php } ?>

    What I need is for <div id=”header”> to be generated regardless of what page you’re on. This is a fallback in case the user hasn’t set a featured image.

    If the page has a featured image then I need the #header to have that image as it’s background, which I’ve accomplished with the code in #1 above.

    Then on the homepage, I’m going to have the background image run through a series of slides, so I need something like <div id=”header” class=”slide”> like I’ve put in #2 above.

    It’s probably pretty simple. I hope I’ve explained myself cleary enough for someone to understand.

    Thanks for the help.

    Assuming the code you’ve posted is working correctly for your site, then you’d probably want something like this:

    <?php
$headerAttributes = "";
if ( has_post_thumbnail( $post->ID ) ) {
    $image = wp_get_attachment_image_scr( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );
    $headerAttributes = $headerAttributes . " " . 'style="background-image: url(' . $image[0] . ')"';
}
if ( is_front_page() || is_home() ) {
    $headerAttributes = $headerAttributes . ' class="slide"';
}
echo '<div id="header"' . $headerAttributes . '>';
?>

    This is just one of many ways to do this, but it should give you enough of an idea to tailor it to your own style.

    Thanks for the help, JPry. Perfect! Although you mispelt wp_get_attachment_image_scr 🙂

    Just pasting final code in case anyone else ever needs to use this.

    <?php
$headerAttributes = "";
if ( has_post_thumbnail( $post->ID ) ) {
	$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );
	$headerAttributes = $headerAttributes . " " . 'style="background-image: url(' . $image[0] . ')"';
}
if ( is_front_page() || is_home() ) {
	$headerAttributes = $headerAttributes . ' class="slide"';
}
echo '<div id="header"' . $headerAttributes . '>';
?>
