Please see below the filter I am using to change the upload directory for my custom post-type.
My custom post-type name is 'download'
My new directory for uploads in my custom post-type 'download' is now... wp-content/downloads/
The problem is in doing this, is that I my image thumbnails are missing because the attachment meta data is looking for the thumbnail in the original directory wp-content/uploads/.
How can I adjust my filter or fix the problem so the attachment data for this custom post-type only uses the new directory wp-content/downloads/
Thanks is advance for any advice or help.

}
you could make custom posttype templates, and in those code custom get attachmentfunctions.
http://codex.wordpress.org/Post_Type_Templates
this custom code could look for the post_meta key: _wp_attached_file.
<?php $attachment_file = get_post_meta($current_post_id, '_wp_attached_file', false); ?>

I added the following code to my functions.php file in WordPress 6.1.1 to display excerpts.
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
function new_excerpt_more($more) {
return '...';
}
add_filter('excerpt_more', 'new_excerpt_more');
...but I also have a use case to show the full excerpt without a read more link.
On page template 1 I add the below code to display the excerpt:
<?php echo the_excerpt(); ?>
...and it displays the excerpt as per the functions.php file but how do I create a 2nd excerpt without the read more link and apply it to page template 2?
Is there a parameter I can use within the_excerpt(parameter); or can I use something like wp_trim_excerpt https://developer.wordpress.org/reference/functions/wp_trim_excerpt/ maybe?
I came across the below code that is supposed to do what I want
function wpex_get_excerpt( $args = array() ) {
// Default arguments.
$defaults = array(
'post' => '',
'length' => 40,
'readmore' => false,
'readmore_text' => esc_html__( 'read more', 'text-domain' ),
'readmore_after' => '',
'custom_excerpts' => true,
'disable_more' => false,
);
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_defaults', $defaults );
// Parse arguments, takes the function arguments and combines them with the defaults.
$args = wp_parse_args( $args, $defaults );
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_args', $args );
// Extract arguments to make it easier to use below.
extract( $args );
// Get the current post.
$post = get_post( $post );
// Get the current post id.
$post_id = $post->ID;
// Check for custom excerpts.
if ( $custom_excerpts && has_excerpt( $post_id ) ) {
$output = $post->post_excerpt;
}
// No custom excerpt...so lets generate one.
else {
// Create the readmore link.
$readmore_link = '' . $readmore_text . $readmore_after . '';
// Check for more tag and return content if it exists.
if ( ! $disable_more && strpos( $post->post_content, '<!--more-->' ) ) {
$output = apply_filters( 'the_content', get_the_content( $readmore_text . $readmore_after ) );
}
// No more tag defined so generate excerpt using wp_trim_words.
else {
// Generate an excerpt from the post content.
$output = wp_trim_words( strip_shortcodes( $post->post_content ), $length );
// Add the readmore text to the excerpt if enabled.
if ( $readmore ) {
$output .= apply_filters( 'wpex_readmore_link', $readmore_link );
}
}
}
// Apply filters and return the excerpt.
return apply_filters( 'wpex_excerpt', $output );
}
Output using:
<?php echo wpex_get_excerpt ( $defaults = array(
'length' => 40,
'readmore' => true,
'readmore_text' => esc_html__( 'read more', 'wpex-boutique' ),
'custom_excerpts' => true,
) ); ?>
...but doesn't seem to workas intended. Outputs the excerpt with no link but the args don't see to work when changed. Would be perfect for my use otherwise. Maybe someone sees how to fix this code?
Thanks
I have created a recently viewed script which generated a shortcode which I then inserted into my home page.
The script is designed so that people who may have visited my website and left, once they come back can see instantly what products they had been viewing on their last visit.
I have placed the shortcode [woocommerce_recently_viewed_products]
and have generated the shortcode using the following script:
function rc_woocommerce_recently_viewed_products( $atts, $content = null ) {
// Get shortcode parameters
extract(shortcode_atts(array(
"per_page" => '5'
), $atts));
// Get WooCommerce Global
global $woocommerce;
// Get recently viewed product cookies data
$viewed_products = ! empty( $_COOKIE['woocommerce_recently_viewed'] ) ? (array) explode( '|', $_COOKIE['woocommerce_recently_viewed'] ) : array();
$viewed_products = array_filter( array_map( 'absint', $viewed_products ) );
// If no data, quit
if ( empty( $viewed_products ) )
return __( 'You have not viewed any product yet!', 'rc_wc_rvp' );
// Create the object
ob_start();
wc_setcookie( 'woocommerce_recently_viewed', implode( '|', $viewed_products ) );
}
// Get products per page
if( !isset( $per_page ) ? $number = 4 : $number = $per_page )
// Create query arguments array
$query_args = array(
'posts_per_page' => $number,
'no_found_rows' => 1,
'post_status' => 'publish',
'post_type' => 'product',
'post__in' => $viewed_products,
'orderby' => 'rand'
);
// Add meta_query to query args
$query_args['meta_query'] = array();
// Check products stock status
$query_args['meta_query'][] = $woocommerce->query->stock_status_meta_query();
// Create a new query
$r = new WP_Query($query_args);
// If query return results
if ( $r->have_posts() ) {
$content = '<ul class="rc_wc_rvp_product_list_widget">';
// Start the loop
while ( $r->have_posts()) {
$r->the_post();
global $product;
$content .= '<li>
<a href="' . get_permalink() . '">
' . ( has_post_thumbnail() ? get_the_post_thumbnail( $r->post->ID, 'shop_thumbnail' ) : woocommerce_placeholder_img( 'shop_thumbnail' ) ) . ' ' . get_the_title() . '
</a> ' . $product->get_price_html() . '
</li>';
}
$content .= '</ul>';
}
// Get clean object
$content .= ob_get_clean();
// Return whole content
return $content;
}
// Register the shortcode
add_shortcode("woocommerce_recently_viewed_products",
"rc_woocommerce_recently_viewed_products");
Everything seems to have registered. However,when I test this myself. I view a few products, go back to the homepage where the shortcode is registered and I see the text
You have not viewed any product yet!
I can not figure out what might be missing in order to register and show the products which I or a potential customer may have viewed.
Woocommerce only save the recently viewed cookie IF woocommerce_recently_viewed_products WIDGET is ACTIVE! See code in wc-product-functions.php wc_track_product_view() function.
Code to save the cookie always in functions.php:
/**
* Track product views. Always.
*/
function wc_track_product_view_always() {
if ( ! is_singular( 'product' ) /* xnagyg: remove this condition to run: || ! is_active_widget( false, false, 'woocommerce_recently_viewed_products', true )*/ ) {
return;
}
global $post;
if ( empty( $_COOKIE['woocommerce_recently_viewed'] ) ) { // #codingStandardsIgnoreLine.
$viewed_products = array();
} else {
$viewed_products = wp_parse_id_list( (array) explode( '|', wp_unslash( $_COOKIE['woocommerce_recently_viewed'] ) ) ); // #codingStandardsIgnoreLine.
}
// Unset if already in viewed products list.
$keys = array_flip( $viewed_products );
if ( isset( $keys[ $post->ID ] ) ) {
unset( $viewed_products[ $keys[ $post->ID ] ] );
}
$viewed_products[] = $post->ID;
if ( count( $viewed_products ) > 15 ) {
array_shift( $viewed_products );
}
// Store for session only.
wc_setcookie( 'woocommerce_recently_viewed', implode( '|', $viewed_products ) );
}
remove_action('template_redirect', 'wc_track_product_view', 20);
add_action( 'template_redirect', 'wc_track_product_view_always', 20 );
You need to set the cookie when you are viewing a single product page so use something like this where I set the cookie to equal the product ID I just viewed. In your case you'll need to get the cookie value if it exists then append the new product to the list of products.
function set_user_visited_product_cookie() {
global $post;
if ( is_product() ){
// manipulate your cookie string here, explode, implode functions
wc_setcookie( 'woocommerce_recently_viewed', $post->ID );
}
}
add_action( 'wp', 'set_user_visited_product_cookie' );
Below code to set cookie 'woocommerce_recently_viewed' worked for me. Hope it helps other
$Existing_product_id = $_COOKIE['woocommerce_recently_viewed'];
if ( is_product() )
{
$updated_product_id = $Existing_product_id.'|'.$post->ID;
wc_setcookie( 'woocommerce_recently_viewed', $updated_product_id );
}
Here's the issue: I am trying to add multiple customer uploaded images to a woocommerce product order.
This is what my current function looks like to generate the fields before the add cart button (This displays properly and allows for a customer to select a file from their computer to upload):
function my_special_fields(){
if (get_the_title() == "My Special Product"){
echo '<table>
<tbody>
<tr>
<td>
<input type="file" name="my_image_upload" id="my_image_upload" multiple="false" />
</td>
</tr>
</tbody>
</table>';
}
}
Which I call with the hook:
add_filter('woocommerce_before_add_to_cart_button', 'my_special_fields');
I then use another hook for adding the item data to the cart:
add_action( 'woocommerce_add_cart_item_data', 'save_my_special_fields', 10, 2 );
And the function called with that hook looks like this:
function save_my_special_fields( $cart_item_data, $product_id ) {
// I save a lot of fields in here that are working fine so ignoring those for now
// This is where I try and find my file to upload
if( ! empty( $_FILES ) ) {
foreach( $_FILES as $file ) {
if( is_array( $file ) ) {
$attachment_id = upload_user_file( $file );
}
}
}
}
It calls this piece of code I found for uploading files into wordpress: https://hugh.blog/2014/03/20/wordpress-upload-user-submitted-files-frontend/
function upload_user_file( $file = array() ) {
require_once( ABSPATH . 'wp-admin/includes/admin.php' );
$file_return = wp_handle_upload( $file, array('test_form' => false ) );
if( isset( $file_return['error'] ) || isset( $file_return['upload_error_handler'] ) ) {
return false;
} else {
$filename = $file_return['file'];
$attachment = array(
'post_mime_type' => $file_return['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
'post_content' => '',
'post_status' => 'inherit',
'guid' => $file_return['url']
);
$attachment_id = wp_insert_attachment( $attachment, $file_return['url'] );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attachment_data = wp_generate_attachment_metadata( $attachment_id, $filename );
wp_update_attachment_metadata( $attachment_id, $attachment_data );
if( 0 < intval( $attachment_id ) ) {
return $attachment_id;
}
}
return false;
}
Right now I am not assigning to any post or doing anything with the image other than trying to get it to upload so that as an Admin I can view it in my media folder.
I think the issue is that the woocommerce form for the add to cart fields might not have this encoding:
enctype="multipart/form-data
Any help on implementing this without getting additional woocommerce plugins would be much appreciated.
So i make custom form-tag in contact form 7! It is a drop down with list of my courses and now I want to make it required because that is the main thing in whole form.
So can someone give me a tip how to do that?
When I do the [myCustomField* course-name class:custom-field]
It does not working with *
So if someone can help it will be great!
I have been working on this myself this afternoon and I do not think Mahmoud has added everything that is needed to get the validation working well and the messages showing up.
using what I have learnt from the posts on contact form 7 here:
https://contactform7.com/2015/01/10/adding-a-custom-form-tag
https://contactform7.com/2015/02/27/using-values-from-a-form-tag/
and looking at this file in the plugin: contact-form-7/modules/select.php which helped a lot.
I think this will work better and needs to be added to your functions.php file in your child-theme.
add_action( 'wpcf7_init', 'custom_add_form_tag_myCustomField' );
function custom_add_form_tag_myCustomField() {
wpcf7_add_form_tag( array( 'myCustomField', 'myCustomField*' ),
'custom_myCustomField_form_tag_handler', true );
}
function custom_myCustomField_form_tag_handler( $tag ) {
$tag = new WPCF7_FormTag( $tag );
if ( empty( $tag->name ) ) {
return '';
}
$validation_error = wpcf7_get_validation_error( $tag->name );
$class = wpcf7_form_controls_class( $tag->type );
if ( $validation_error ) {
$class .= ' wpcf7-not-valid';
}
$atts = array();
$atts['class'] = $tag->get_class_option( $class );
$atts['id'] = $tag->get_id_option();
if ( $tag->is_required() ) {
$atts['aria-required'] = 'true';
}
$atts['aria-invalid'] = $validation_error ? 'true' : 'false';
$atts['name'] = $tag->name;
$atts = wpcf7_format_atts( $atts );
$myCustomField = '';
$query = new WP_Query(array(
'post_type' => 'CUSTOM POST TYPE HERE',
'post_status' => 'publish',
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'ASC',
));
while ($query->have_posts()) {
$query->the_post();
$post_title = get_the_title();
$myCustomField .= sprintf( '<option value="%1$s">%1$s</option>',
esc_html( $post_title ) );
}
wp_reset_query();
$myCustomField = sprintf(
'<span class="wpcf7-form-control-wrap %1$s"><select %2$s>%3$s</select>%4$s</span>',
sanitize_html_class( $tag->name ),
$atts,
$myCustomField,
$validation_error
);
return $myCustomField;
}
That is how we create the custom tag. The important differences here are the addition of the $validation_error variables as wells the aria-required and aria-invalid data. It is also important to include the $validation_error in the final output so that we can see the validation messages being created.
Then to finish it off we need to add some validation via filters.
There is no documentation on this yet, but I used the functions from the select.php and altered them to what I needed.
/* Validation filter */
add_filter( 'wpcf7_validate_myCustomField', 'wpcf7_myCustomField_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_myCustomField*', 'wpcf7_myCustomField_validation_filter', 10, 2 );
function wpcf7_myCustomField_validation_filter( $result, $tag ) {
$tag = new WPCF7_FormTag( $tag );
$name = $tag->name;
if ( isset( $_POST[$name] ) && is_array( $_POST[$name] ) ) {
foreach ( $_POST[$name] as $key => $value ) {
if ( '' === $value ) {
unset( $_POST[$name][$key] );
}
}
}
$empty = ! isset( $_POST[$name] ) || empty( $_POST[$name] ) && '0' !== $_POST[$name];
if ( $tag->is_required() && $empty ) {
$result->invalidate( $tag, wpcf7_get_message( 'invalid_required' ) );
}
return $result;
}
This code should also go in your functions.php file just under the code for the custom CF7 tag.
Here the filter's first string $tag should match with the class that is being generated in the custom CF7 tag so if your custom tag->type = 'myCustomField' then the $tag of the filter must include the name, like so wpcf7_validate_myCustomField as well as the required version of it, wpcf7_validate_myCustomField*.
I hope that helps anyone else looking for this.
If you want even more of the options available from the backend of Contact Form 7 check the select.php file as it lays it out quite nicely on how to get each option and include it.
You can use [select*] to output a required drop-down menu.
[select* course-name include_blank "English" "Math"]
Check https://contactform7.com/checkboxes-radio-buttons-and-menus/
EDIT:
So you have your own shortcode [myCustomField]. To make two versions of your shortcode as [myCustomField] and [myCustomField*] you have to pass both shortcodes to your function as the following:
add_action( 'wpcf7_init', 'wpcf7_add_form_tag_mycustomfield' );
function wpcf7_add_form_tag_mycustomfield() {
wpcf7_add_form_tag( array( 'myCustomField', 'myCustomField*'),
'wpcf7_mycustomfield_form_tag_handler', array( 'name-attr' => true ) );
}
function wpcf7_mycustomfield_form_tag_handler( $tag ) {
$tag = new WPCF7_FormTag( $tag );
if ( empty( $tag->name ) ) {
return '';
}
$atts = array();
$class = wpcf7_form_controls_class( $tag->type );
$atts['class'] = $tag->get_class_option( $class );
$atts['id'] = $tag->get_id_option();
$atts['name'] = $tag->name;
$atts = wpcf7_format_atts( $atts );
$html = sprintf( '<your-tag %s></your-tag>', $atts );
return $html;
}
Then, you can use it:
[myCustomField course-name class:custom-field]
or
[myCustomField* course-name class:custom-field]

I am able to download files to metabox thanks to this code.
Output of the database is looks like what i show in the below

I want to delete the images that i dont want with delete_post_meta method while i am selecting checkboxes on my update page.
$galleri = get_post_meta($id,'my_files',true);
<div class="galeri">
<?php
foreach($galleri as $galeri){

}
?>
</div>
I appreciate if you help me
Try this:
Use update_post_meta() function instead of delete_post_meta().
While using delete_post_meta(), it will delete custom fields.
So if you want to delete particular one file. You need to use update_post_meta().
$string = 'a:2:{i:0;a:3:{s:4:"file";s:48:"D:xampphtdocswp/wp-content/uploads/2016/08/2.jpg";s:3:"url";s:52:"http://localhost/wp/wp-content/uploads/2016/08/2.jpg";s:4:"type";s:10:"image/jpeg";}i:1;a:3:{s:4:"file";s:59:"D:xampphtdocswp/wp-content/uploads/2016/08/2da83a4s-960.jpg";s:3:"url";s:63:"http://localhost/wp/wp-content/uploads/2016/08/2da83a4s-960.jpg";s:4:"type";s:10:"image/jpeg";}}';
$arr = unserialize($string); //USE get_post_meta() function instead of
$index = array_search('http://localhost/wp/wp-content/uploads/2016/08/2da83a4s-960.jpg',array_column( $arr, 'url')); //search index
echo $index;
if (array_key_exists($index,$arr))
{
unset($arr[$index]); //remove array index
}
print_r($arr); //array with only value.
//use array_values() to reindex
update_post_meta($post_id, 'my_files', $arr); //update post meta
