english is not my native language but I try my best to descripe my problem to you.
Iam working on a plugin for WooCommerce, I dont think that is really relevant but anyway...
I have set-up an custom-post-type, and also assigned a custom-taxonomy to that post-type.
For each custom-taxonomy-term I create an metabox on the product-type.
Every metabox is unique cause I pass the term-slug.
function add_post_meta_boxes() {
$args = array(
'type' => 'product',
'taxonomy' => 'picto_group',
'orderby' => 'term_group',
'order' => 'ASC'
);
$groups = get_categories($args);
foreach($groups as $group) {
//
$slug = $group->slug;
$name = $group->name;
$count = $group->category_count;
$desc = $group->category_description;
$catid = $group->cat_ID;
add_meta_box(
'i3_picto_'.$slug, // Unique ID
$name.' - '.$count, // Title
'i3_picto_meta_box', // Callback function
'product', // Admin page (or post type)
'normal', // Context
'low', // Priority
array($slug, $catid, $desc)// Arguments to pass into the callback function
);
}// End foreach
}
This metabox is than filled with all the posts which have the custom-term.
function i3_picto_meta_box( $object, $box ) {
$slug = $box['args'][0];
$catid = $box['args'][1];
$desc = $box['args'][2];
?>
<p>
<?php
$args = array(
'post_type' => 'product_picto', // Post-Type name
'numberposts' => -1,
'tax_query' => array(
array(
'taxonomy' => 'picto_group', // Taxonomy name
'field' => 'id',
'terms' => $catid // Term ID
)
)
);
$pictograms = get_posts( $args );
foreach ( $pictograms as $pictogram ) :
setup_postdata( $pictogram );
$pslug = $pictogram->post_name;
$checked = get_post_meta($pictogram->ID, 'cb-one[cb-'.$slug.'_'.$pslug.']', true);
?>
<div class="group-<?php echo $slug; ?>-<?php echo $pslug; ?>">
<label for="cb-<?php echo $slug; ?>_<?php echo $pslug; ?>">
<?php echo get_the_post_thumbnail( $pictogram->ID, 'thumbnail' ); ?>
<?php the_title(); ?>
<?php the_content(); ?>
<input type="checkbox" name="cb-one[cb-<?php $slug; ?>_<?php $pslug;?>']" id="cb-<?php echo $slug; ?>_<?php echo $pslug; ?>" <?php if( $checked == true ) { ?>checked="checked"<?php } ?> />
</label>
</div>
<?php
endforeach;
wp_reset_postdata();
?>
</p>
<?php }
All posts show the title, thumbnail and content.
I will also display a check box in every post. So as I edit some products, I am able to check some post of some categories. In the end these post should show also in the front end.
Now I am having big trouble with how I can save the state for every check box. Because all my metaboxes are auto-generated, and as you can see also my checkbox-field has an auto-generated name of "term-slug" + "post-slug".
How can I pass the generated check box-field name to my save_post function?
I think I named my check box-fields in the wrong way and I also think I need to run an foreach-loop on the update_post_meta in my save function?
Maybe I am thinking too complicated here.
Maybe someone can understand this and have some useful information for me.
Thanks, Mo
UPDATE
Hey guys,
so today I worked on and updated my code. I can now already save my metaboxes and also the checked state. But something is not quite right yet.
I hope its ok that I edit my Question instead of commenting.
The new checkbox code looks like this:
<input type="checkbox" name="cb-one[]" id="cb-<?php echo $slug; ?>_<?php echo $pslug; ?>" value="<?php echo $pid; ?>" <?php checked( in_array( $pid, $pictoarray ) ); ?> />
And the function to save the metabox looks like this:
function i3_save_post_class_meta( $post_ID ) {
global $post;
if(isset( $_POST['cb-one'] ))
{
$custom = $_POST['cb-one'];
$old_meta = get_post_meta($post->ID, '_cb-one');
// Update post meta
if(!empty($old_meta)){
update_post_meta($post->ID, '_cb-one', $custom );
} else {
add_post_meta($post->ID, '_cb-one', $custom );
}
}
}
To be able to also get the checked=checked state of the single checkboxes I added this code to the top of my i3_picto_meta_box function:
global $post;
$pictolist = get_post_meta( $post->ID, '_cb-one');
if (!empty($pictolist[0])) {
$pictoarray = $pictolist[0]; // Get the right array
}
Here Iam getting the metadata as an array and on the input element I check if the value of that element is also in that array.
With these updates I can now select multiple checkboxes in my post/product. The ID´s of the selected posts get saved and I can also retrieve them in the frontend.
Iam working with checkboxes becaus I want to be able to also uncheck them in the future.
So I tried this, I selected multiple checkboxes and saved the post. After that I unchecked every checkbox and saved again.
Unfortunatly all checkboxes stayed checked!
Than I unchecked just one box and saved, everything was fine. I continued with this one-by-one just to find out, that everytime the last checkbox always stays checked.
I can uncheck all boxes except one. As soon as I save the post one checkbox will still be checked.
I hope someone can help me fix this problem.
Thanks, Mo
