Post edit background meta checkbox WordPress

Tom Mills comments:

oh awesome thanks :)

Fahad Murtaza comments:

Did you set any value for $prefix

If so, what is that?

Fahad Murtaza comments:

I see your field name is

$prefix . 'background',

Lets suppose that the prefix value is 'prefixvalue_' then the following code will give you the value of background field

<?
$bgvalue = get_post_meta(get_post_parent_ID(), 'prefixvalue_background', false);
echo $bgvalue;

?>

Let me know if it helps. I am doing exactly the same with no problem.

that

Fahad Murtaza comments:

Now lets use the $bgvalue variable for your specific need

<?php if ($bgvalue=='geomap') { ?>



echo ‘do stuff’;



<?php } elseif ($bgvalue=='video') { ?>



echo ‘do stuff’;



<?php } elseif ($bgvalue=='img') { ?>



echo ‘do stuff’;

<?php } ?>

<?php } ?>

Tom Mills comments:

The prefix is dtb_

$prefix = 'dbt_';

Hope this helps,

best wishes,

tom

Fahad Murtaza comments:

Here is the updated code based on your prefix value


<?php
$bgvalue = get_post_meta(get_post_parent_ID(), 'dtb_background', false);
echo $bgvalue;
?>
<?php if ($bgvalue=='geomap') { ?>
echo 'do stuff';
<?php } elseif ($bgvalue=='video') { ?>
echo 'do stuff';
<?php } elseif ($bgvalue=='img') { ?>
echo 'do stuff';
<?php } ?>
?>


Tom Mills comments:

Thanks - can i ask where does bgvalue come from ?

I have put in this code but i get

Call to undefined function get_post_parent_id()

thanks and best wishes,

tom

Fahad Murtaza comments:

Sorry, my bad. try the following

<?php
$bgvalue = get_post_meta(get_the_ID(), 'dtb_background', false);
echo $bgvalue;
?>
<?php if ($bgvalue=='geomap') { ?>
echo 'do stuff';
<?php } elseif ($bgvalue=='video') { ?>
echo 'do stuff';
<?php } elseif ($bgvalue=='img') { ?>
echo 'do stuff';
<?php } ?>
?>


Fahad Murtaza comments:

The $bgvalue comes from the metabox that you have created using the library.

Tom Mills comments:

Thanks I have tried the code above - oddly 'Array' gets printed on the webpage. But it does not work i am afraid :(

This is what it says on delux blog tips for checking checkbox and display

Get value of field with multiple values

There’re some fields that may have multiple values such as select, checkbox_list. To get (or check) values of these fields, use this code:

$metas = get_post_meta(get_the_ID(), 'meta_key', false);

// if you want to show values
foreach ($metas as $meta) {
echo $meta;
}

// if you want to check if a value $val is set or not
if (in_array($val, $metas)) {
echo "$val is set";
} else {
echo "$val is not set";
}


and here is my metabox

$meta_boxes[] = array(

'id' => 'Background options',

'title' => 'Background options',

'pages' => array('post', 'film', 'page'),

'fields' => array(

array(

'name' => 'You must choose a background',

'id' => $prefix . 'background',

'type' => 'checkbox_list',

'options' => array(

'video' => 'video',

'geomap' => 'Map',

'img' => 'Image',

),

'desc' => 'Choose your background'

)

)

);


I cant see bgvalue here - does it come from somwhere else in the meta scipt ?

thanks and ebst wishes,

tom

Hi


I am going to test it locally and recreating the whole sample for you.

Just a few more mins.

Fahad Murtaza comments:

Also I am assuming you are already able to see the metabox in your wordpress admin when you create/edit post. And you are also able to the save the value for the background.

My code just helps you with the front end which gets the value for a single value field called 'dtb_background' as per your defined metabox using the library.

I sent you a PM. Please check.

HI All,

Fahd helped me find answer over the weekend. Hopefully this will be helpful to others.

<?php

// The follwing line just checks if the post ID being retrieved is correct. If this matches the post ID from
//observing the ID in wp-admin, then its correct
//echo get_the_ID();


// Get the post meta data for custom field i.e dbt_background which is $prefix and ''background''concatenated
$checkbox_list = get_post_meta(get_the_ID(), 'dbt_background', false);

// Checking if the array is not empty. Anything above 0 means there are one or more checkboxes that were selected
//echo "Total checkboxes =" .count($checkbox_list);

//// if you want to show values, for testing

//foreach ($checkbox_list as $checkbox_list) {
//print_r($checkbox_list);
// echo $checkbox_list;
//}

// The following line outputs every single meta key and its calue
//the_meta(); ?>


<?php if (in_array('geomap', $checkbox_list)) {
echo "1";
?>

do something


<?php } elseif (in_array('img', $checkbox_list)) {
echo "2";
?>

do something else


<?php } elseif (in_array('pano', $checkbox_list)) { ?>

or do this


<?php } ?>


Thanks for everybodies help with this one - it is really appreciated. WP Questions is new to me, so not quite worked out best way to reward good answers and the person that did the work.
