将鼠标悬停在图像上的图像描述

Question

I am no expert in PHP, javascript and js; so I am hoping someone can help me in easy language terms. I have just developed my first wordpress site and changed the code immensely, using this forum - thanks heaps so far!

The site: http://www.heritageglass.com.au

My request: text (description of image in media library) hovering over image.

Just like this website or this plugin , I have found several questions on this site that refer to my issue but they haven't seemed to help or I don't exactly know where to place this as it's grabbing the_title and I want the_description . Is there such a term?

PHP code in portfolio.php template:

<div data-id="post-<?php the_ID(); ?>" data-type="<?php
  $categories = get_the_category();
  $count = count($categories);
  $i=1;
  foreach($categories as $category) {
      echo str_replace('-', '', $category->slug);
      if ($i<$count) echo ' '; $i++;} ?>" class="post-<?php the_ID(); ?>
      <?php
        $categories = get_the_category();
        foreach($categories as $category) {
            echo str_replace('-', '', $category->slug).' '; } ?> project portfolio-item-wrap">
    <div class="portfolio-item">
        <?php if ( has_post_thumbnail() ) { ?>
        <a class="portfolio-item-img" href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_post_thumbnail( 'portfolio-image' ); ?></a>
        <?php } ?>


        <h4><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
        <p>
            <?php
            $categories = get_the_category(); 
            $temp = array();
            foreach($categories as $category) {
                if ($category->category_parent == 0) continue;
                $temp[] = str_replace('-', '', $category->name); 
            } 
            echo implode(", ", $temp);
            ?>
        </p>
    </div>
</div>

I found this: Text over image using jquery and css and added the script in the header.php. And used my .portfolio-item and .portfolio-item-img instead of .wrapper and .description - but that didn't do anything.

Hoping someone can lead me in the right direction?

Thanks!

在四年前我在WordPress论坛上进行搜索时，不确定是否是您需要的，但这可能会为您指明正确的方向。

$img_desc = $image->post_excerpt;

When editing a post, add two custome field, one for title, one for descritption. Our code goes like this:

$dataType = '';
$divClass = '';

$categories = get_the_category();
$count = count($categories); 
$i=1; 
foreach($categories as $category) {
    $dataType .= str_replace('-', '', $category->slug); 
    $divClass .= str_replace('-', '', $category->slug).' ';
    if ($i<$count) $dataType.= ' ';
    $i++;
}

$metaList = get_post_meta(get_the_ID());
$title = isset($metaList['title']) ? $metaList['title'] : '';
$description = isset($metaList['description']) ? $metaList['description'] : '';

// now we have title and description for the thumb!
?>
<div data-id="post-<?php the_ID(); ?>" data-type="<?php echo $dataType;?>"
    class="post-<?php the_ID(); echo $divClass;?>  project portfolio-item-wrap">
    <div class="portfolio-item">
        <?php if ( has_post_thumbnail() ) { ?>
            <a class="portfolio-item-img" href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
                <?php the_post_thumbnail( 'portfolio-image' ); ?>
            </a>
        <?php } ?>


        <h4><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
        <p>
            <?php
                $temp = array();
                foreach($categories as $category) {
                    if ($category->category_parent == 0) continue;
                    $temp[] = str_replace('-', '', $category->name); 
                } 
                echo implode(", ", $temp);
            ?>
        </p>
    </div>
</div>

I have found the answer after sooooo much research.

This is the answer: How do I get the featured image description from my wordpress page?

enter the the_post_thumbnail_caption(); within the span tags and set your span tags class in css.

done.

Thanks to all of you for your help!
