How to echo checkbox group with multidimentional array - php

Question

I need help to get the data from my checkbox-group with multidimensional array options to reflect in my post page(single.php code). Radio type is working well but the checkbox-group type is not. I added on the bottom the sample code found in my single.php for the radio type which query the data to my post page for your reference.
Here's the array from my metabox.php code:
<?php
// array
$prefix = 'wtf_';
$meta_box = array( 'id' => 'site',
'title' => 'Program Details',
'page' => 'post',
'context' => 'normal',
'priority' => 'high',
'fields' => array(
array('name' => 'Principal Return',
'desc' => 'Principal Return After Expiry or Not',
'id' => $prefix . 'principal',
'type' => 'radio',
'options' => array(
array('name' => ' Yes ', 'value' => 'Yes-after expiry'),
array('name' => ' No ', 'value' => 'No-included on the interest')
)
),
array(
'name' => 'Compounding',
'desc' => 'Choose if compounding is allowed or not',
'id' => $prefix . 'compounding',
'type' => 'radio',
'options' => array(
array('name' => ' Yes ', 'value' => 'Allowed'),
array('name' => ' No ', 'value' => 'Not Allowed'),
array('name' => ' Re-purchase', 'value' => 'Yes thru re-purchase')
)
),
array ('name' => 'Payment Processors',
'desc' => 'Payment Processsor Accepted',
'id' => $prefix.'processors',
'type' => 'checkbox_group',
'options' => array(
array('label' => ' Liberty Reserve ', 'value' =>'LR'),
array('label' => ' SolidTrustPay ', 'value' =>'STP'),
array('label' => ' EgoPay ', 'value' =>'EgoPay'),
array('label' => ' Perfect Money ', 'value' =>'PM'),
array('label' => ' Payza ', 'value' =>'Payza'),
array('label' => ' PayPal ', 'value' =>'PayPal'),
array('label' => ' Bankwire ', 'value' =>'Bankwire')
))))
// Callback function to show fields in meta box
function mytheme_show_box() {
global $meta_box, $post;
// Use nonce for verification
echo '<input type="hidden" name="mytheme_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />';
echo '<table class="form-table">';
foreach ($meta_box['fields'] as $field) {
// get current post meta data
$meta = get_post_meta($post->ID, $field['id'], true);
echo '<tr>',
'<th style="width:20%"><label for="', $field['id'], '">', $field['name'], '</label></th>',
'<td>';
switch ($field['type']) {
case 'text':
echo $statetemt;
break;
case 'textarea':
echo $statetemt;
break;
case 'select':
echo $statetemt;
break;
case 'radio':
foreach ($field['options'] as $option) {
echo $statetemt; }
break;
case 'checkbox':
foreach ($field['options'] as $option) {
echo $statetemt;}
break;
case 'checkbox_group':
foreach ($field['options'] as $option) {
echo '<input type="checkbox" value="'.$option['value'].'" name="'.$field['id'].'[]" id="'.$option['value'].'"',$meta && in_array($option['value'], $meta) ? ' checked="checked"' : '',' />',$option['label']; }
echo '<br /><span class="description">'.$field['desc'].'</span>';
break;
}
//From my single.php code <<<<=================
<div class="sdinfo"><strong>Principal Return</strong>:<span><?php $principal = get_post_meta(get_the_ID(), 'wtf_principal', true);
if (isset($principal[0])) {
echo $principal ;
} else if (isset($principal[1])) {
$principal = get_post_meta(get_the_ID(), 'wtf_principal', true);
echo $principal;
} else {_e('Not Available');} ?></span></div>
<div class="sdinfo"><strong>Program Started</strong>:<span> <?php $started = get_post_meta(get_the_ID(), 'wtf_started', true); if (isset($started[0])) { echo $started;
} else {_e('Not Available');} ?></span></div>
<div class="sdinfo"><strong>Compounding</strong>:<span>
<?php $compounding = get_post_meta(get_the_ID(), 'wtf_compounding', true);
if (isset($compounding[0])) {
echo $compounding ;
} else if (isset($compounding[1])) {
$compounding = get_post_meta(get_the_ID(), 'wtf_compounding', true);
echo $compounding;
} else if (isset($compounding[2])) {
$compounding = get_post_meta(get_the_ID(), 'wtf_compounding', true);
echo $compounding;
} else {_e('Not Available');} ?></span></div>
?>

Answer 1

All what you need is point an array using var_dump($array) to check where and what data you need from arrays fields.
Second you need to get foreach() function. For example you want grab an array of data:
'priority' => 'high', should be as example:
echo $meta_box["priority"] which will result as value of array: high
If you are not sure and not familiar with array use as simple:
foreach ($meta_box as $arr)
{
var_dump($arr);
#then play and manipulate how to grab a fields a data:
foreach ($arr["fields"][""] as $fa)
{
var_dump($fa["name"]);
var_dump($fa["desc"]);
var_dump($fa["desc"]);
}
#...
}
Learn how to grab via var_dump() if you unsure with array of data.
Payment Processors LR STP EgoP
echo $meta_box["fields"][""]["name"];
Than you need grab a data of an array:
foreach ($meta_box["fields"][""]["options"] as $options)
{
foreach ($options as $options_key)
{
foreach ($options_key as $opt_val)
{
$result .= ' '.$opt_val;
}
}
}
