I am using add post meta function to save some data and its not working
<?php
//include '../../../wp-blog-header.php';
$unique = "true";
$pageID = $_GET['postID'];
echo "pageID:";
echo $pageID;
echo "</br>";
$num_posts = $_GET['num_posts'];
echo "num_posts: ";
echo $num_posts;
echo "</br>";
$num_posts_meta_key = "num_posts";
add_post_meta($pageID, $num_posts_meta_key, $num_posts , $unique) or update_post_meta($pageID, "num_posts" , $num_posts);
?>
Can someone help me out?
In first page I am getting all values from textboxes or checkboxes in javascript and then i am passing it in URL to next page where add_post_meta function is there.
I tried using method POST ...but then it doesnt work for me. It just submit the page and come back w/o doing anything on 1st page. I tried with GET method..but nothing works.
Hence I decided to take all values like num of post, post id in javascript and then from there pass it with url by using window.location.
I am very new to wordpress plugin coding. I thought POST method in my plugin is conflicting with some other post method in post.php..not sure though..
I am writing plugin for admin panel.
not sure what your problem is.. are you sure you're passing the right postID parameter? does the post exist in the database?
You don't really need to do add_post_meta() or update_post_meta.
From the manual:
The first thing this function will do
is make sure that $meta_key already
exists on $post_id. If it does not,
add_post_meta($post_id, $meta_key,
$meta_value) is called instead and its
result is returned.
<?php
// This minimum code should work, though you should really check that a post
// with this id does exist.
update_post_meta($_GET['postID'], "num_posts" , $_GET['num_posts']);
?>

I'm working on a project where I upload a file and use its path in a shortcode. Right now I've hard-coded the post's ID into my code but I want to make it dynamic so that new posts automatically get the correct shortcode.
<?php
global $wpdb;
$thepost = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM $wpdb->postmeta WHERE post_id = 5574" ) );
echo do_shortcode ('[sgpx gpx="'.'/wp-content/uploads/' . $thepost->meta_value . '"]');
?>
Going off of what #Damocles said, you are really setting yourself up for trouble with your current path. Instead, there are built-in WordPress functions that abstract away the database and utilize caching that you are strongly encouraged to use.
// Get the current WordPress post
$the_post = get_post();
//If we have a value (there are cases where this will be empty)
if($the_post){
// Get the value from the post meta table by the current post's ID
$the_post_meta = get_post_meta($the_post->ID, 'YOUR_META_KEY_HERE', true);
// Double-check that we have a value
if($the_post_meta) {
// Finally, echo the shortcode
echo do_shortcode ('[sgpx gpx="'.'/wp-content/uploads/' . $the_post_meta . '"]');
}
}
There are several ways to get the current post however get_post() is the most common. If you are in a custom loop, however, you might need to adjust accordingly.
To access the meta, use get_post_meta() which includes some optimizations including use a cache instead of the database.
Although there are definitely exceptions, generally speaking, if you are working with WordPress and you find yourself writing SQL statements, there is almost always a better, safer, faster, etc. way to do it using core functions.
Guys I'm writting a wordpress site to run a knowldge base for our Service desk. As one person will be updating it i needed to have a field for who wrote the kb artical. I'm tring to add a custom field into my wordpress theme to display writtenby using Advance custom Fields. Now I'm using echo Knowledge Base plugin for knowldge base.
I've got as far add ing code below will display the text below the last up date value that plugin creates. However i cannot get it to put value from the custom field on the page after this. The plugin creates the page using php below the ive added the two lines as below.
$wb = get_post_meta($post->ID, 'Writtenby', true);
echo ' Last Update Writtenby:'.$wb.' ';
// LAST UPDATED ON
public static function last_updated_on( $args ) {
echo '' . esc_html( $args['config']['last_udpated_on_text'] ) . ' ' . EPKB_Utilities::get_formatted_datetime_string( $args['article']->post_modified, 'F d, Y' ).'';
$wb = get_post_meta($post->ID, 'Writtenby', true);
echo ' Last Update Written by:'.$wb.' ';
}
Advanced Custom Fields plugin use a little bit different system to store postmeta. Try to use get_field() instead get_post_meta()
If you have the ID
$customField = get_post_meta($my_id, "_mcf_customField", true);
However if you want to get the ID from the object:
$customField = get_post_meta($post_id->ID, "_mcf_customField", true);
After much more work looks like at the point the page was being created it had no reference to partical page not even a current one. They where writting to an array all artical numbers and info.
So by telling get_field which artical to get the writtenby field from it now displayed data and not blank
$wb= get_field('Writtenby', $args['article']->ID);
I'm using WordPress ACF plugin to store users' data.
The values I'm calling in template are as below:
echo $uid=get_current_user_id();
echo $lesson_order = get_field('lesson_order', 'user_'.$uid);
echo $last_lesson_time = get_field('last_lesson_time', "user_".$uid);
The values returned for admins are correct, but when logged in as a subscriber, the code returns empty values. I also checked user ids, which appear to be correct.
Can someone give me a solution to this. Thanks a lot.
I've tested both option on a local project and both were working but have you tried retrieving the user ID using this instead?
<?php
$current_user = wp_get_current_user();
echo "Current User ID " . $current_user->ID;
?>
If it still doesn't work, can you show a little more of your code?

What I am trying to do is each time a logged in user opens single.php I log a post meta activity. Essentially I want to know every time a logged in user reads a post. So I put this in single.php inside the loop and after having checked if user is logged in.
First I got just '6' (which is the post ID) in my post, so I added some echo to find which function was doing that and this is what resulted.
echo "before post meta<br />";
add_post_meta( the_ID(), 'post_read', (string)$current_user->ID );
echo "after post meta<br />";
prints out in my post:
before post meta
6after post meta
Why is add_post_meta printing '6' (the post ID)? How can I get rid of it? An incidentally when I:
$post_reads = get_post_custom_values('post_read', the_ID());
All I get is '6' again.
the_ID is printing out the post ID. Use get_the_ID to return it without printing.
You are using the_ID() in your function call. the_ID() displays the id to screen. You want to use get_the_ID() instead. This will give you a usable ID you can use for your function call.
i have create a redir.php and placed in the home directory of wordpress to do the redirect. I want to pass in the post id and then retrieve a custom field value of the post and feed into header('location:'.$url);
www.mysite.com/redir.php?id=30
in redir.php will retrieve post id=30 custom field value and pass it into $url.
this is what I have, but it's not working. It gives me "Parse error: parse error in \redir.php on line 5".
it looks like wordpress environment is not being loaded.
<?php
require('./wp-blog-header.php');
$id = $_GET['id'];
$url= get_field('deal_http_link',post->$id);
header('Location:'.$url);
?>
thanks
Your script has multiple issues:
There is whitespace before the opening <?php tag, so the redirect wouldn't work because the headers will have already been sent. Instead, <?php should be the very first thing in the file.
post->$id is invalid syntax. You probably meant the $id variable which you defined in the preceding line.
To retrieve the value of a custom field, use get_post_meta(), not get_field().
Try something like this instead:
<?php
require('./wp-blog-header.php');
$id = $_GET['id'];
$url = get_post_meta($id, 'deal_http_link', true);
header('Location: ' . $url);
exit();
