After creating new post I need to generate and store the .vcf file in storage. I don't know how I can do this after post save. Didn't find help to develop such function. Please help!
Try this :
On "save_post" hook you can write function. That will create .vcf file with the name of post_title at specified directory.
function my_project_create_vCard( $post_id ) {
$vpost = get_post($post->ID);
$filename = strtolower(str_replace(" ","-",$vpost->post_title)).".vcf";
header('Content-type: text/x-vcard; charset=utf-8');
header("Content-Disposition: attachment; filename=".$filename);
$data=null;
$data.="BEGIN:VCARD\n";
$data.="VERSION:2.1\n";
$data.="FN:".$vpost->post_title."\n"; // get post title
$data.="EMAIL:" .get_field('email',$vpost->ID)."\n"; // get acf field value
$data.="END:VCARD";
$filePath = get_template_directory()."/".$filename; // you can specify path here where you want to store file.
$file = fopen($filePath,"w");
fwrite($file,$data);
fclose($file);
}
add_action( 'save_post', 'my_project_create_vCard' );

I'm trying to pre-populate the File upload field with files already submitted previously, using ACF PRO and ACF Frontend Form.
So far, I am able to retrieve a list of files that was previously uploaded but can't seem to figure out a way to set it in the file upload frontend.
The File upload field lives inside a Repeater group.
In the functions.php:
I added a load_value with key set to the repeater group:
add_filter('acf/load_value/key=field_5e80ed8f4516b', 'my_acf_set_file_list', 10, 3);
Then in the function I attempted to set the $value to be an array of file urls.
'field_5e80edf14516c' is the key for the File field.
function my_acf_set_file_list( $value, $post_id, $field ){
$order_id = $_GET['order'];
$value = array();
// get existing files
$existing_files = get_post_meta( $order_id, 'file', true);
if ( !empty( $existing_files ) ) {
$i = 0;
foreach ( $existing_files as $file ) {
$value[$i]['field_5e80edf14516c'] = $file;
// also tried
// $value[$i]['field_5e80edf14516c'] = $file['file'];
}
}
return $value;
}
The problem is in the frontend form, there seems to be no change at all. No file was pre-populated.
I'm pretty sure I didn't get the array structure correct, but I've searched all over and cannot find any related information.
The post data for when I upload existing files seem to indicate the attachment ID is used. But I'm not sure what is the row-0 and other id 5ebf042bba99f?
acf[field_5e80ed8f4516b]:
acf[field_5e80ed8f4516b][row-0][field_5e80edf14516c]: 381
acf[field_5e80ed8f4516b][5ebf042bba99f][field_5e80edf14516c]: 381
acf[field_5e80ed8f4516b][5ebf042cba9a0][field_5e80edf14516c]: 401
Thanks in advance!
I have to create a json file when a term is created/updated/deleted from a taxonomy "product_cat", below i attempt to register a simple json file but without success :
add_action( 'create_term', 'wpse_create_term', 10, 3 );
add_action( 'created_term', 'wpse_created_term', 10, 3 );
add_action( 'edited_term', 'wpse_edited_term', 10, 3 );
add_action( 'delete_term', 'wpse_delete_term', 10, 5 );
function wpse_create_term(){
createJsonFile();
}
function wpse_created_term(){
createJsonFile();
}
function wpse_edited_term(){
createJsonFile();
}
function wpse_delete_term(){
createJsonFile();
}
function createJsonFile(){
echo "begin write to json file to " . dirname(__FILE__);
$data = array("a","b","c","d");
//format the data
$formattedData = json_encode($data);
//set the filename
$filename = 'members.json';
//open or create the file
$handle = fopen($filename,'w+');
//write the data into the file
fwrite($handle,$formattedData);
//close the file
fclose($handle);
}
Firstly, why those hooks never fired ( the echo is not printed when updating a term ) ? and how should i specify destination folder for the final json file?
Thanks for your help.
You cant echo something from the function file you might want to use the debug.log for it
Secondly you need to specify a location where to create the json file
I want to get the duration of audio file when uploaded through custom field and save it in the post meta.
WordPress has built in audio functions using the ID3 library that will help you achieve this.
First you will hook into ACF using the acf/save_post hook. Then you will use the WP function wp_read_audio_metadata() to get the meta data of the audio file. Lastly you will use the update_post_meta() function to save the data to the post. Something like this:
function save_audio_duration($post_id) {
// Get the WP Uploads Directory (where ACF saves files)
$uploads = wp_upload_dir();
$uploads_dir = ( $uploads['baseurl'] . $uploads['subdir'] );
// Get the file name from ACF & create the file string
$file_obj = get_field('audio_file', $post_id);
$file = $uploads_dir . '/' . $file_obj['filename'];
// Use the wp_read_audio_metadata() function to get data
$metadata = wp_read_audio_metadata( $file );
// Save the file length to the post meta
update_post_meta($post_id, 'audio_length', $metadata['length']);
}
// Will execute AFTER post has been saved (change "20" to "1" to execute before)
add_action('acf/save_post', 'save_audio_duration', 20);
Note: $metadata['length'] will return the time in seconds while $metadata['length_formatted'] will return the time in a formatted string.
Note x2: If you change the "20" to "1" in the action to execute this BEFORE the fields are saved to the post you will need to change the get_field() function to $_POST['audio_file'] as the function will be executed before ACF saves the fields to the DB.
I change a little your good code for vídeos:
function save_video_duration($post_id) {
// Get the file name from ACF & create the file string
$file_obj = get_field('video_file', $post_id);
// Get the WP Uploads Directory (where ACF saves files)
$file = get_attached_file( attachment_url_to_postid( get_field('video_file', $post_id) ) );
// Use the wp_read_audio_metadata() function to get data
$metadata = wp_read_video_metadata($file);
// Save the file length to the post meta
update_post_meta($post_id, 'video_file_length', $metadata['length']);
}
// Will execute AFTER post has been saved (change "20" to "1" to execute before)
add_action('acf/save_post', 'save_video_duration', 20);
Thanks
I am working on my personal wordpress site that distribute images.
In single post page, I registered several images via ACF(Advanced Custom Fields) and I know how to get image path/filename through get_field ACF function.
I just googled then found this page, but how can I apply this technique to wordpress site?
Download multiple images into zip
Now I am stuck...
On single post page, place the url of download_zip.php file, where you will place all your code for creating zip.
On single post page:
Download ZIP
In variable 'model_id', place the post id of the single post.
Now create a download_zip.php file on the root of your wordpress setup, where wp-config.php file exists.
Here is the code of download_zip.php file.
<?php
/*File for downloading the gallery zip files*/
$post_id = $_GET['model_id'];
require_once('wp-blog-header.php');
require_once('/wp-admin/includes/file.php');
WP_Filesystem();
$files_to_zip = array();
$zip = new ZipArchive();
$title = get_the_title($post_id);
$destination = wp_upload_dir();
//var_dump($destination);
$destination_path = $destination['basedir'];
$DelFilePath = str_replace(" ","_",$title).'_'.$post_id.'_'.time().'.zip' ;
$zip_destination_path = $destination_path."/".$DelFilePath;
if(file_exists($destination_path."/".$DelFilePath)) {
unlink ($destination_path."/".$DelFilePath);
}
if ($zip->open($destination_path."/".$DelFilePath, ZIPARCHIVE::CREATE) != TRUE) {
die ("Could not open archive");
}
//this is only for retrieving Repeater Image custom field
$row1 = get_field('acf_field_name1',$post_id);
$row1 = get_field('acf_field_name2',$post_id);
$rows = array($row1,$row2);
if($rows) {
foreach($rows as $row): ?>
<?php
$explode = end(explode("uploads",$row));
$index_file = array($destination_path,$explode);
$index_file = implode("",$index_file);
$new_index_file = basename($index_file);
$zip->addFile($index_file,$new_index_file);
endforeach;
}
$zip->close();
if(file_exists($zip_destination_path)) {
send_download($zip_destination_path);
}
//The function with example headers
function send_download($file) {
$basename = basename($file);
$length = sprintf("%u",filesize($file));
header($_SERVER['SERVER_PROTOCOL'].' 200 OK');
header('Content-Description: File Transfer');
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename="'.$basename.'"');
header('Content-Transfer-Encoding: binary');
header('Pragma: public');
header('Content-Length: ' . $length);
set_time_limit(0);
ob_clean();
flush();
readfile($file); // "Outputs" the file.
unlink($file);
}
?>
Please modify this code according to your requirement such as get_field(), place your image field name inside it, & define your upload directory, so that you can break the url in $explode variable for defining path of image in $index_file variable.
And please also check your destination path stored in $destination_path variable is correct or not.
Hope, this may be helpful to you.
wp_get_attachment_url() process full file path like
http://example.com/wp-content/uploads/2014/12/aura.mp3
I want the url without http://example.com/
So, I want above example as wp-content/uploads/2014/12/aura.mp3 instead of http://example.com/wp-content/uploads/2014/12/aura.mp3. How to do it?
You can really easily explode it by / and then take the part with index 3. Example
$url = wp_get_attachment_url(id); //id is file's id
$urllocal = explode(site_url(), $url)[1]; //output local path
Here is the WordPress way using WordPress functions (avoid hacking):
$fullsize_path = get_attached_file( $attachment_id ); // Full path
$filename_only = basename( get_attached_file( $attachment_id ) ); // Just the file name
WordPress has tons of functions, so first try to find the function on the docs: https://developer.wordpress.org/reference/functions/get_attached_file/
You can use PHP's function explode.
Here is the code:
<?php
$image_url = wp_get_attachment_url( 9 ); //ID of your attachment
$my_image_url = explode('/',$image_url,4);
echo $my_image_url[3];
?>
You can implode your entire url on / and array_slice from the end, then implode it back in on /.
$url = wp_get_attachment_url($item->ID); //id is file's id
$url_relative = implode(array_slice(explode('/', $url),-3,3),'/');
//Returns: 2019/08/image.jpg
That way if your WordPress is on a subdomain or localhost or the images are on S3 it won't crash.
