Add Excerpt to custom Wordpress Gallery? WordPress

Emma comments:

Hey this is the full code:

Where do i place yours inside it?

The excerpt is from the post page

<?php if ( have_posts() ) while ( have_posts() ) {
the_post();
global $post;

$strGalleryClass = '';
$strPostContent = '';
if (trim($post->post_content))
{
$strGalleryClass .= ' wpscls-with-content';
$strPostContent .= '<h2 class="wpscls-field-title wpscls-'.$post->post_name.'">'. get_the_title() .'</h2>';
$strPostContent .= '<div class="wpscls-field-content">';
ob_start();
the_content();
$strPostContent .= ob_get_contents();
ob_end_clean();
$strPostContent .= '</div>';
}

$arrArgs = array (
'posts_per_page' => 0,
'post_parent' => $post->ID,
'post_status' => 'any',
'orderby' => 'menu_order',
'order' => 'ASC',
'post_type' => array('attachment'),
);

$the_query = new WP_Query( $arrArgs );
$rows_img = $the_query->posts;
$numItemsPerRow = 100;
$strResultGallery = '';
$strResultGallery .= '<table class="cls-table-gallery'.$strGalleryClass.'">';
$strResultGallery .= '<tr>';
$strResultGallery .= $strPostContent ? '<td class="wpscls-post-content">'.$strPostContent.'</td>' : '';

if (count($rows_img) > 0 && !is_page())
{
foreach ($rows_img as $numKey01 => $row_img)
{
$strFullImg = $row_img->guid;
$numTmpPos = strpos($strFullImg, '.', strlen($strFullImg) - 5);
$strExt = strtolower(substr($strFullImg, $numTmpPos));
$strThumb = substr($strFullImg, 0, $numTmpPos).$strExt;
if ($strExt == '.jpg' || $strExt == '.jpeg' || $strExt == '.gif' || $strExt == '.png')
{
$strResultGallery .= '<td>'.'<img alt="'.$row_img->post_title.'" src="'.$strThumb.'" />';
$strResultGallery .= '<h5>'.'&nbsp;'.'</h5>';
$strResultGallery .= '<div class="capt"><h6>'.'.$row_img->post_title.'.'</h6></div>';
$strResultGallery .= '</td>';
}
}
}
$strResultGallery .= '</tr>';
$strResultGallery .= '</table>';

if (count($rows_img) > 0 || $strPostContent) echo $strResultGallery;
break;
}
?>

if you want the image caption, try replacing this line

$strResultGallery .= '<div class="capt"><h6>'.'$excerpt = get_the_excerpt();'.'</h6></div>';

with

$strResultGallery .= sprintf( '<div class="capt"><h6>%s</h6></div>', $row_img->post_excerpt );

What does the SprintF bit do? This hasn't worked either

Emma comments:

I only want it to show if there is an excerpt, my div and h6 style is showing without any text in it.

Dbranes comments:

You have to edit the images in the media library to add the caption, so most likely it's empty in your case.

Here is a nice tutorial how you can do it:

ps: sprintf() is just another way of constructing strings from variables.

Dbranes comments:

To check if the image caption is set, you can do:


if( ! empty( $row_img->post_excerpt ) ){
$strResultGallery .= sprintf( '<div class="capt"><h6>%s</h6></div>', $row_img->post_excerpt );
}


Emma comments:

Hey this works however it doesn't show on the image I place it on.

Dbranes comments:

ok, looks like we are getting there ;-)

You might try to add captions to other images as well to test.


ps: it's also handy to debug with echo, print_r or var_dump

Emma comments:

haha thanks, i will give it a try, it seems to show on any random image i place it on. Maybe it's my div?

Dbranes comments:

I installed this theme on my localhost and it seems to work with the above changes,
i.e. I created a post, attached few images, added the image caption during upload,
and they are displayed under each image on the front-end.
