Hoping someone can help. I've put this code into a standard template but no images are displaying, despite the fact that I've got a bunch of posts with images.
<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
$images =& get_children( array (
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type' => 'image'
));
if ( empty($images) ) {
// no attachments here
} else {
foreach ( $images as $attachment_id => $attachment ) {
echo wp_get_attachment_image( $attachment_id, 'thumbnail' );
}
}
endwhile; endif; ?>
Thanks for helping!
change
echo wp_get_attachment_image( $attachment_id, 'thumbnail' );
to
echo wp_get_attachment_image( $attachment->ID, 'thumbnail' );
and
$images =& get_children( array (
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type' => 'image'
));
to
$images =get_posts( array (
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type' => 'image'
));
you should use get_posts()
You can do something like this:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post();
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
);
$attachments = get_posts( $args );
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
echo wp_get_attachment_image( $attachment->ID, 'full' );
}
}
endwhile; endif; ?>
This code will fetch all the 'large' images from the media library and display them
Hope this is what you were looking for

This is what I have now in my page-name.php:
<?php
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' => null,
'post_parent' => null, // any parent
'post_mime_type' => 'image'
);
$attachments = get_posts($args);
if ($attachments) {
$attachment_meta = wp_get_attachment($attachment->ID);
foreach ($attachments as $post) {
if ($attachment_meta['caption'] == 'Ceahlau' ){
setup_postdata($post);
echo wp_get_attachment_image( $attachment->ID, 'full' );
the_attachment_link($post->ID, false);
}
}
}
?>
And this is what I have in functions.php:
function wp_get_attachment( $attachment_id ) {
$attachment = get_post( $attachment_id );
return array(
'alt' => get_post_meta( $attachment->ID, '_wp_attachment_image_alt', true ),
'caption' => $attachment->post_excerpt,
'description' => $attachment->post_content,
'href' => get_permalink( $attachment->ID ),
'src' => $attachment->guid,
'title' => $attachment->post_title
);
}
$attachment_meta = wp_get_attachment($attachment->ID);
Can you please tell me what is wrong with my functions? I want to post image only if they have "Ceahlau" in caption.
I have a while loop that gets all pages of a certain category on index.php which is my posts page.
However, I want to change the code below, so if it is the homepage, it does not run this loop but displays some text.
This code the loop works:
<?php
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
$loop = new WP_Query( array(
'post_type' => 'story',
'cat' => $cat_id,
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC'
) );
while ( $loop->have_posts() ) : $loop->the_post();
?> <?php the_title();?>
endwhile;
?>
In this code, nothing loads on any page except the homepage:
<?php
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
$loop = array(
'post_type' => 'story',
'cat' => $cat_id,
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC' ,
'paged'=>$paged
);
if ( is_home() ) {
echo 'Welcome!';
} else if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php endwhile; endif; ?>
You need to wrap your query and loop in your is_home() condition
if ( !is_home() ) { // This is not the home page
// Add your query and loop here
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
$loop = new WP_Query( array(
'post_type' => 'story',
'cat' => $cat_id,
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC'
) );
while ( $loop->have_posts() ) : $loop->the_post();
?> <?php the_title();?>
endwhile;
} else { // This is the homepage
echo 'Some text here';
}
<?php
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
$loop = new WP_Query( array(
'post_type' => 'story',
'cat' => $cat_id,
'posts_per_page' => 10,
'orderby' => 'date',
'order' => 'DESC'
) );
if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $the_query->the_post();
if ( is_home() ) {
echo 'Welcome!';
}
else{?>
<h2><a href="<?php echo get_permalink(); ?>"><?php the_title();
}
<?php endwhile; endif; ?>
I want to implement a variation of the code below. This code currently shows a post's attachment title.
How I can modify the code so if there is no attachment it shows the post title.?
This is code for pulling first attachment title.
<?php $args = array( 'post_type' => 'attachment', 'orderby' => 'menu_order', 'order' => 'ASC', 'post_mime_type' => 'image' ,'post_status' => null, 'numberposts' => 1, 'post_parent' => $post->ID );
$attachments = get_posts($args);
if ($attachments) {
foreach ( $attachments as $attachment ) {
$image_title = $attachment->post_title;?>
<?php echo $image_title; ?><?php } } ?>
Something like this?
<?php
$args = array( 'post_type' => 'attachment', 'orderby' => 'menu_order', 'order' => 'ASC', 'post_mime_type' => 'image' ,'post_status' => null, 'numberposts' => 1, 'post_parent' => $post->ID );
$attachments = get_posts($args);
if ($attachments) {
foreach ( $attachments as $attachment ) {
$image_title = $attachment->post_title;
if($image_title) {
echo $image_title;
} else {
the_title();
}
}
}
The best way to do this would be the empty() function and a ternary expression
$image_title = ( ! empty( $attachment->post_title) )?
$attachment->post_title: // use the attachment title if it is not empty
$post->post_title; // otherwise use the post title
How can I get images to have the alt set to "slider"?
This is my code:
$args = array(
'post_parent' => $post->ID,
'post_type' => 'attachment',
'orderby' => 'menu_order',
'order' => 'ASC',
'numberposts' => 5,
'post_mime_type' => 'image'
);
if ( $images = get_children( $args ) ) {
echo '<div id="sliderbody" style="width:640px; height:480px;"><div id="slider">';
foreach( $images as $image ) {
echo wp_get_attachment_image( $image->ID, 'trueslider' );
}
echo '</div></div>';
}
I guess you're trying to set the alt attribute to always be "slider" so try this
$args = array(
'post_parent' => $post->ID,
'post_type' => 'attachment',
'orderby' => 'menu_order',
'order' => 'ASC',
'numberposts' => 5,
'post_mime_type' => 'image'
);
if ( $images = get_children( $args ) ) {
echo '<div id="sliderbody" style="width:640px; height:480px;"><div id="slider">';
foreach( $images as $image ) {
echo wp_get_attachment_image( $image->ID, 'trueslider', false, array('alt' => 'slider') );
}
echo '</div></div>';
}
I'm trying to add the image caption to the alt attribute of images in a gallery but my code doesn't work. Below is part of the gallery shortcode modified to implement a slideshow. On the bottom I am using wp_get_attachment_image() with $default_attr as the array of attributes containing the caption. The caption does not show in HTML.
$id = intval($id);
if ( 'RAND' == $order )
$orderby = 'none';
if ( !empty($include) ) {
$include = preg_replace( '/[^0-9,]+/', '', $include );
$_attachments = get_posts( array('include' => $include, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
$attachments = array();
foreach ( $_attachments as $key => $val ) {
$attachments[$val->ID] = $_attachments[$key];
}
} elseif ( !empty($exclude) ) {
$exclude = preg_replace( '/[^0-9,]+/', '', $exclude );
$attachments = get_children( array('post_parent' => $id, 'exclude' => $exclude, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
} else {
$attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
}
if ( empty($attachments) )
return '';
if ( is_feed() ) {
$output = "\n";
foreach ( $attachments as $att_id => $attachment )
$output .= wp_get_attachment_link($att_id, $size, true) . "\n";
return $output;
}
$i = 0;
$default_attr = array(
'src' => $src,
'class' => "attachment-$size",
'alt' => trim(strip_tags( $attachment->post_excerpt ))
);
foreach ( $attachments as $attachment ) {
<a href='".wp_get_attachment_url($attachment->ID)."'>".wp_get_attachment_image($attachment->ID, $size, false, $default_attr)."</a>
}
return $output;
You can use:
wp_get_attachment_url($attachment->post_title);
Came through this while searching for the same answer, found it and wanted to share it:
$attachment=get_post($attachment_id);
$alt = get_post_meta($attachment->ID, '_wp_attachment_image_alt', true);
$image_title = $attachment->post_title;
$caption = $attachment->post_excerpt;
$description = $image->post_content;
to output your caption formatted by wordpress (adding breaks and paragraphs) you can just use:
$caption = apply_filters('the_content', $caption);
