alt attributes not showing on pages

Question

I have downloaded a wordpress theme called livepuse, and unfortunately the alt tags are not showing on portfolio pages for my images. The website is as follows: http://vitul3ddesigns.com/project/listed-buildings/

the code snippet from the theme is as follows:

<div class="thumbs">
                                                <?php
                                                    foreach ($images as $att) {
                                                        // get image's source based on size, can be 'thumbnail', 'medium', 'large', 'full' or registed post thumbnails sizes
                                                        $src = wp_get_attachment_image_src($att, 'full');
                                                        $src = $src[0];?>
                                                                <a href="">
                                                                <img src="
                                                                <?php if($rscript == 'TimThumb'){ ?>
                                                                    <?php bloginfo('template_directory');?>/scripts/timthumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;a=t&amp;q=95&amp;zc=1 
                                                                <?php } elseif($rscript == 'PHP Thumb'){ ?>
                                                                    <?php bloginfo('template_directory');?>/phpThumb/phpThumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;q=95&amp;zc=1 
                                                                <?php } elseif($rscript == 'Disable Resize Script'){ ?>
                                                                    <?php echo $attachment[0];?>
                                                                <?php } else{?>
                                                                    <?php bloginfo('template_directory');?>/scripts/timthumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;a=t&amp;q=95&amp;zc=1 
                                                                <?php }?>

                                                                " alt=""/>
                                                </a>
                            <?php
                                                    }
                                                    ?>
                                    </div>

Thanks for your help in advance...

Answer 1

alt="<?php echo get_post_meta($att, '_wp_attachment_image_alt', true); ?>"

This should do the trick. The alt of an image is set in a custom meta field called "_wp_attachment_image_alt".

Answer 2

@Luke Tulley

From your code it seems the alt tags are there but are empty, there are a number of ways you can define them, a simple way is to use the post title:

 alt="<?php the_title(); ?>"

Or alternativly use a custom field and use the get_post_meta function.

http://codex.wordpress.org/Function_Reference/get_post_meta

New code:

<?php
foreach ($images as $att) {
    $alttag = get_post_meta($post->ID, 'Alt', true);
    $src = wp_get_attachment_image_src($att, 'full');
    $src = $src[0];?>
    <a href="">
    <img src="
    <?php if($rscript == 'TimThumb'){ ?>
    <?php bloginfo('template_directory');?>/scripts/timthumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;a=t&amp;q=95&amp;zc=1 
    <?php } elseif($rscript == 'PHP Thumb'){ ?>
    <?php bloginfo('template_directory');?>/phpThumb/phpThumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;q=95&amp;zc=1 
    <?php } elseif($rscript == 'Disable Resize Script'){ ?>
    <?php echo $attachment[0];?>
    <?php } else{?>
    <?php bloginfo('template_directory');?>/scripts/timthumb.php?src=<?php echo $src; ?>&amp;w=70&amp;h=40&amp;a=t&amp;q=95&amp;zc=1 
    <?php }?>
    " alt="<?php echo $alttag; ?>"/>
    </a>
<?php } ?>

Now in your new post in wordpress use 'Alt' as the name of your custom field then enter the desired value for your alt tag.

Can't see the custom fields box in the new post area? Under the screen options you can check to display them.
