Wordpress meta tag challenge - php

I'm currently trying to create a site for TV shows and due to certain wordpress limitations this is becoming a challenge.
However I bypass that with the use of implementing custom meta fields in the functions.php file, now my problem is that I need it to actively create new fields when I submit information in the current field. For example custom metabox names are
(Episode Name="This is It") (Episode Number="1") (Season Number="5")
Instead of having to create all the boxes from the beginning I would like the use Javascript (jQuery) or any solution to automatically create a new set of these 3 boxes
(Episode Name="") (Episode Number="") (Season Number="")
so I can just enter the new information as they come. Thank you in advance for your help!
Note: I have invested too much time into wordpress to just switch to another cms, so that is not an option at this point in time.

from what I understand of your question, you are looking for a simple solution to automate the input process. I have a general idea of what it is you nee to achieve as I have had to do something similar on a brochure type of website.
I have tried answering your question using Jquery, but I find it to increase the amount of text input required when creating your post, there is unfortunately no completely automated method of doing it, but hopefully below would provide you with a solution.
first I found the following plugin: Types - Complete Solution for Custom Fields and Types here: http://wordpress.org/extend/plugins/types/
This allows you to create custom meta feilds when creating a new post/page. The custom feilds are brought added with a perfix of "wpcf-" and then the name of the field, e.g. "Episode Name" becomes "wpcf-episode-name" in the database.
The following is an edit of wordpress's get_meta function:
function get_specifications(){
if ( $keys = get_post_custom_keys() ) {
echo '<div class="entry_specifications">';
foreach ( (array) $keys as $key ) {
$keyt = trim($key);
if ( '_' == $keyt[0] )
continue;
$values = array_map('trim', get_post_custom_values($key));
$value = implode($values,', ');
//remove "wpcf-"
$key = str_replace('wpcf-','',$key);
//convert "-" to a space " "
$key = str_replace('-',' ',$key);
//check if it has a value, continue if it does, skip if it doesn't:
if ($value <> ''){
echo apply_filters('the_meta_key', "
<div class='meta_wrapper'>
<div class='meta_title'>$key</div>
<div class='meta_value'>$value</div>
</div>\n", $key, $value);
};
}
}
// echo '</div>'; comment out and remove the line below if you are not using floats in your css
echo '</div><div class="clear"></div>';
}
In my page.php (or your template-page.php) I have added the following code when/where I want the meta to be produced:
<?php
//check to see if there is meta data, as you only want the meta data on TV Program pages
$met_check = get_post_meta($post->ID, 'wpcf-features', true);
if ($met_check <> ''){
//if it has a value, spit out "About EpisodeName" ?>
<h2 class="post-title clear">About <?php echo $title ?></h2>
<?php //perform the function from functions.php and return results:
echo get_specifications();
}
?>
I've styled the result with the following CSS:
.meta_entry {
clear:both;
}
.meta_title {
float:left;
text-transform:capitalize;
width:200px;
}
.meta_value {
float:left;
width:480px;
}
Hope this helps mate!

There is a wonderful plugin for wordpress called Pods which might be a viable solution.

How to get the image links from Gutenberg block gallery and add them as html data attributes to a button in wordpress

I'm using gutenberg gallery block inside a post and I'm trying to create a button which contains all of the image ids in the gallery block as html data attributes such that later when I output the content to the page I can have access to those ids using javascript. Basically I'm trying to create a lightbox feature for a custom post type.
The problem is that I can't get access to the gutenberg gallery block data.
Here's my code
while ($custom_post_type->have_posts()) {
$custom_post_type->the_post();
$gallery = get_post_gallery(get_the_id(), false);
$ids = explode(",", $gallery['ids']);
}
And here's that button with html data attributes
<button class="gallery"
<?php
for ($i = 0; $i < count($ids); $i++) {
$img_link = wp_get_attachment_image_url($ids[$i], 'full');
echo "data-img-" . $i . " = " . $img_link . " ";
}?>
>
Light-box
</button>
But it does not work, $ids is empty. It prints out this
<button class="gallery">Light-box</button>
Thanks for your help!
Edit
I'm using wordpress blocks on the post page, I'm not quite certain how they have been generated, but they work out of the box.
"it does not work, $ids is empty."
That block is one of the default wordpress blocks, aka "core blocks". In order to have access to its data you would need to use parse_blocks function not get_post_gallery. That's why your variable is empty.
So the overall workflow to get what you're looking for would be:
Check whether your post has any blocks or not, using has_block function. has_blockDocs
If it does, then get all of the blocks (including gallery block) using parse_blocks function. parse_blocksDocs
parse_blocks will return an array of all blocks used in your post, so loop through them and see which one is called "core/gallery".
"core/gallery" block has "attributes" and "ids" for each image you've added in the admin panel.
Once you get the "ids", you should be able to create your custom button and image links using wp_get_attachment_image_url function. wp_get_attachment_image_urlDocs
As a POC:
Please see the following code:
if (has_block("gallery", get_the_content()))
{
$post_blocks = parse_blocks(get_the_content());
foreach ($post_blocks as $post_block)
{
if ("core/gallery" == $post_block["blockName"])
{
$ids = $post_block["attrs"]["ids"];
}
}
}
And this is the button:
<button class="gallery"
<?php
for ($i = 0; $i < count($ids); $i++) {
$img_link = wp_get_attachment_image_url($ids[$i], "full");
echo "data-img-" . $i . " = " . $img_link . " ";
}
?>
>
Light Box
</button>
Which will return:
Note:
I've used get_the_content function, assuming that you're in the loop based on the code you provided in your question. If you're not in the loop or you would need to use the code outside of the loop you could use global $post; $post->post_content; instead.
This answer has been tested on wordpress 5.8 and works.

Trim text in WP (php)

I am new to php and trying to trim the lines of text generated by the ('information') part of the code seen below (in my custom WP theme):
<div class="information"><?php echo get_post_meta(get_the_ID(),'information',true); ?></div>
Each post has a different lenght of it's information (basically like a excerpt, but pulled from a custom field in each post) text, which messes up my archive/blog page, as i use a 3 columns grid. I need the lenght of all posts seen on the archive page to be equally long, by restricting the "information" text to be no more than lets say 150 characters long.
I see the fenction in this piece of code for example, taken from a default WP file, but can't seem to wrap it around my own piece of code seen above, to make it work like i want it to:
<?php
et_divi_post_meta();
if ( 'on' !== et_get_option( 'divi_blog_style', 'false' ) || ( is_search() && ( 'on' === get_post_meta( get_the_ID(), '_et_pb_use_builder', true ) ) ) ) {
truncate_post( 270 );
} else {
the_content();
}
?>
This is what i want/talk about:
Before:
POST 1
I am a wordpress post, with a long text, that should not be so long, as it makes the 3 column setup of the archive page look stupid.
After:
POST 1
I am a wordpress post, with a long text, that should not be so long...
How do i do this?
Thanks!
You can use substr() php function to get part of the string.
Take a look at this example function.
function trimResult($string, $len = 150){
if(strlen($string)> $len){
$string = substr($string,0,$len) . "..."; // to let the user know that was truncated...
}
return $string;
}
ref: http://php.net/substr
Specific code example, will be a better solution to include the php function on a global file.
<?php
function trimResult($string, $len = 150){
if(strlen($string)> $len){
$string = substr($string,0,$len) . "..."; // to let the user know that was truncated...
}
return $string;
}
?>
<div class="information"><?php echo trimResult(get_post_meta(get_the_ID(),'information',true)); ?></div>
Hope it helps.
$post = "I am a wordpress post, with a long text, that should not be so long, as it makes the 3 column setup of the archive page look stupid.";
$post = mb_strimwidth($post, 0, 70, "...");
echo $post;
result: "I am a wordpress post, with a long text, that should not be so long..."
Add ... if string is too long PHP

ACF plugin, displaying as list instead of comma separated

A plugin for wordpress called Advanced Custom Fields uses a
<?php the_field('field_name'); ?
function to display information that I have determined inside WP admin in posts.
However, it outputs it as a comma separated horizontal list (e.g. cow, milk, farm).
I want to output it like this, in an unordered list:
cow
milk
farm
How would I go by doing this?
add css class to your php call, when you creating list, make list and ul, then as cotent call fields..
For more please share your htm/php file, and css also...
In your php file, save the field in an array, and use foreach to create an li foreach string.
What kind of 'Field type' do u use ?
<?php
$arr = get_the_field('field_name');
$str = explode (",", $arr);
echo '<ul>';
foreach($str as $s){
echo '<li>'.$s.'</li>';
}
echo '</ul>';
?>
OR use this code

Wordpress how to insert multiple CSS via custom field

I am struggling with custom field to insert page specific CSS or JS in Wordpress.
I was able to insert single CSS following the article.
http://www.wpbeginner.com/wp-themes/embed-custom-css-in-your-single-posts-with-custom-fields/
Then I was wondering what if I want to insert multiple CSSs via a custom field.
I guess I have to do with Arrays and loops, right?
Can I just want put multiple CSSs in one field by separating with commas or something?
Example:
in the custom field section:
field name: customCSS
filed value: foo.css, bar.css, other.css ...
Could someone give me an idea how to do it?
Thank you.
My wordpress ver. is 3.8.
I found a solution to this. basic PHP stuff...
I dont know if this is efficient, but I got what I want as a result.
I used comma(,) as a delimiter in the custom field.
if (is_page()) {
$uniqueCSS = get_post_meta($post->ID, uniqueCSS ,true);
$uniqueCSSArr = explode(',', $uniqueCSS);
if($uniqueCSSArr) {
for( $i = 0; $i < count($uniqueCSSArr); $i++ ) {
echo '<link rel="stylesheet" href="'. get_template_directory_uri() .'/css/'. $uniqueCSSArr[$i] .'"/>';
echo "\n";
}
}
}
Thank you

PHP, Advanced Custom Fields, Wordpress, if statement

What am I doing wrong? Just to warn you this is my first attempt at php so pardon my ignorance ;)
Currently using Wordpress with a plugin called Advanced Custom Fields. Which allows you to create custom field options in the backend of wordpress.
http://plugins.elliotcondon.com/advanced-custom-fields/
I am trying to get a div to hide if the value of the Advanced Custom Field "Available" (which is a select list) is set to "No". The div is a marker for the 10 available apartments that overlays a map. Currently it displays all 10 markers whether it's availability is set to "No" or "Yes".
$i = 201;
$available = get_field('available');
while ($i <= 210) :
if ($available == 'No') {
echo '<div id="apt-' . $i . '" class="map-marker" style="display:none;"></div>';
} elseif ($available) {
echo '<div id="apt-' . $i . '" class="map-marker">';
echo $i++;
echo'</div>';
}
endwhile;
what are you trying to accomplish here? the get_field function is a per post in the loop method, so you would need to be iterating over the whole posts collection with the
while ($loop->have_posts()) : $loop->the_post();
if you're not using a custom loop you would leave off the $loop-> part.
you probably need to post the whole page template. you might just need to do some studying on wordpress about the loop and how it works.
