Solved. Using the variable $post_id returns the correct data for that block.
$wf_settings_width = get_field('wf_settings_container_size', $post_id);'
Ok, I have just realised that I am trying to obtain block data, rather than post data that does not exist. Silly me.
My next question is, how do I get the block data, when it isn’t returning any via get_template.
I am building a set of global templates for the blocks which is why I am including them, rather than having the code directly in the template.
I’m guessing you already solved this, but for future reference, this is what I use and it works great. Depending on your own setup, you may want to add more conditional statements to trigger only on certain post types.
function generate_video_thumbnail($post_id, $post) {
$current_post_thumbnail = get_post_thumbnail_id( $post_id );
if ( '' !== $current_post_thumbnail ) {
return;
}
$url = get_field('video_embed', $post_id, false);
$oembed = _wp_oembed_get_object();
$provider = $oembed->get_provider($url);
$oembed_data = $oembed->fetch( $provider, $url );
$thumbnail = $oembed_data->thumbnail_url;
$title = get_the_title($post_id);
if($url) {
$image = media_sideload_image( $thumbnail, $post_id, $title, 'id' );
set_post_thumbnail( $post_id, $image );
}
}
add_action('save_post', 'generate_video_thumbnail', 12, 3);
I just use html entities when adding instructions, to prevent the tags from rendering.
No luck so far unfortunately. I emailed the REST to ACF plugin author (who replied very quickly!) and he confirmed there currently isn’t an action to indicate an item was saved. His only suggestion was a filter that runs prior to saving ACF.
add_action('acf/rest_api/post/prepare_item', function($item, $request){
// do something
}, 10, 2);
Not too sure if that would help anyone else – if someone finds a creative solution please let me know!
For the time being, I’m thinking of just setting up a CRON job to email every x amount of minutes/hours.
Cool, so aside from the duplication, it seems to work fine as the goal is to redirect to the URL if a correct code is entered.
Code so far:
<?php
$codeErr = "";
$code = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["code"])) {
$codeErr = "<strong>Error:</strong> Promo code is required";
} else {
$code = code_input($_POST["code"]);
if (!preg_match("/[A-Za-z0-9]+/",$code)) {
$codeErr = "<strong>Error:</strong> Incorrect promo code. Please try again.";
} else {
$rows = $wpdb->get_results($wpdb->prepare(
"
SELECT *
FROM wp_vrtny1k0kz_postmeta
WHERE meta_key LIKE %s
AND meta_value = %s
",
'promosettings_%_code',
''.$code.''
));
if (!$rows){
$codeErr = "<strong>Error:</strong> Incorrect promo code. Please try again.";
}
}
}
}
function code_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<div class="row">
<div class="col-sm-6 col-xs-12">
<form action="<?php echo get_permalink(); ?>" method="post" id="promo">
<div class="row">
<div class="col-sm-9 col-xs-8">
<input type="text" name="code">
</div>
<div class="col-sm-3 col-xs-4">
<input type="submit" name="submit" value="Submit">
</div>
</div>
</form>
<span class="error"><?php echo $codeErr; ?></span>
</div>
</div>
<?php
if( $rows ) {
foreach( $rows as $row ) {
preg_match('_([0-9]+)_', $row->meta_key, $matches);
$url_key = 'promosettings_' . $matches[0] . '_url';
$url = get_post_meta( $row->post_id, $url_key, true );
?>
<script>
window.location.replace("<?php echo $url; ?>");
</script>
<?php
}
}
Edit – added a counter. Not sure if this is the most effective way, but it works
if( $rows ) {
$i = 0;
foreach( $rows as $row ) {
if($i == 0) {
preg_match('_([0-9]+)_', $row->meta_key, $matches);
$url_key = 'promosettings_' . $matches[0] . '_url';
$title_key = 'promosettings_' . $matches[0] . '_title';
$url = get_post_meta( $row->post_id, $url_key, true );
$title = get_post_meta( $row->post_id, $title_key, true );
echo $url;
echo $title;
}
$i++;
}
}
Ok, so changing
preg_match('_([0-9]+)_', $row->meta_key, $matches);
$meta_key = 'promosettings_' . $matches[0] . '_url';
$url = get_post_meta( $row->post_id, $meta_key, true );
echo $url[0];
to
preg_match('_([0-9]+)_', $row->meta_key, $matches);
$meta_key = 'promosettings_' . $matches[0] . '_url';
$url = get_post_meta( $row->post_id, $meta_key, true );
echo $url;
Now shows me the URL, but duplicated.
The singular image field for a logged out user does not bring up the media gallery, but instead shows just a very basic upload a file from your computer box.
How would this be achieved in ACF 5?
Bumping as I’d like to know if there’s an answer for this.
