PHP nested If statement syntax

Question

Hiya Guys! so I need some help with this:

            <?php

        $newsposts = new WP_Query('cat=restaurant');

        if ( is_front_page()) { echo '<h3 class="member-review">Latest Restaurants</h3>

        <div id="extra">if ($newsposts->have_posts()) : while ($newsposts->have_posts()) : $newsposts->the_post();

        <div class="reslogo"><img src="'echo catch_that_image()' /></div>

        endwhile, endif; 

        </div>';    

        } ?>

What I'm trying to do here is have an image slider of first post images (from restaurant category) display at the bottom of the page. I use DIVs to control placement/ style but I really need help with my PHP syntax ... I just cant figure it out... Any help would be greatly appreciated!

Cheers

Answer 1

you can't run code inside quote since php treats it as string, try this:

<?php
    $newsposts = new WP_Query('cat=restaurant');
    if ( is_front_page()) { 
        echo '<h3 class="member-review">Latest Restaurants</h3>
        <div id="extra">';
        if ($newsposts->have_posts()) : while ($newsposts->have_posts()) : $newsposts->the_post();
            echo '<div class="reslogo"><img src="'.catch_that_image().'"/></div>';
        endwhile, endif; 
        echo '</div>';    
    } 
?>

I would suggest a totally different syntactic approach: instead of echoing HTML from PHP, insert PHP calculated values inside HTML. This makes the code more organized and readable.

<?php $newsposts = new WP_Query('cat=restaurant'); ?>

<?php if ( is_front_page()): ?>
<h3 class="member-review">Latest Restaurants</h3>

<div id="extra">
    <?php if ($newsposts->have_posts()): ?>
        <?php while ($newsposts->have_posts()) : $newsposts->the_post(); ?>

        <div class="reslogo"><img src="<?php echo catch_that_image() ?>" /></div>

        <?php endwhile; ?>
    <?php endif; ?>
</div>';    

Note: I don't know if this code is correct, I just updated the syntax.
