How to add categori selection option in theme option? - php

Question

I am trying to add a category option in my wordpress theme using option tree. I am using this code in theme-option.php
<?php
$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
add_action( 'admin_init', 'custom_theme_options', 1 );
function custom_theme_options() {
$saved_settings = get_option( 'option_tree_settings', array() );
$custom_settings = array(
'sections' => array(
array(
'id' => 'general',
'title' => 'Home Page Settings'
)
),
'settings' => array(
array(
'id' => 'Great-Product',
'label' => 'Great Product',
'desc' => 'select great Product category',
'type' => 'select',
'section' => 'general',
'std' => 'Choose a category',
'options' => $wp_cats
)
)
);
if ( $saved_settings !== $custom_settings ) {
update_option( 'option_tree_settings', $custom_settings );
}
}
?>
But it is not showing any category. Where is my fault? Please tell me.

You need to define $wp_cats variable within your function, or use global to bring it in.
Option 1 (global variable)
<?php
$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
add_action( 'admin_init', 'custom_theme_options', 1 );
function custom_theme_options() {
global $wp_cats; /** GLOBAL!! */
$saved_settings = get_option( 'option_tree_settings', array() );
$custom_settings = array(
'sections' => array(
array(
'id' => 'general',
'title' => 'Home Page Settings'
)
),
'settings' => array(
array(
'id' => 'Great-Product',
'label' => 'Great Product',
'desc' => 'select great Product category',
'type' => 'select',
'section' => 'general',
'std' => 'Choose a category',
'options' => $wp_cats
)
)
);
if ( $saved_settings !== $custom_settings ) {
update_option( 'option_tree_settings', $custom_settings );
}
}
?>
Option 2 (build variable inside function)
<?php
add_action( 'admin_init', 'custom_theme_options', 1 );
function custom_theme_options() {
$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
$saved_settings = get_option( 'option_tree_settings', array() );
$custom_settings = array(
'sections' => array(
array(
'id' => 'general',
'title' => 'Home Page Settings'
)
),
'settings' => array(
array(
'id' => 'Great-Product',
'label' => 'Great Product',
'desc' => 'select great Product category',
'type' => 'select',
'section' => 'general',
'std' => 'Choose a category',
'options' => $wp_cats
)
)
);
if ( $saved_settings !== $custom_settings ) {
update_option( 'option_tree_settings', $custom_settings );
}
}
?>

I have found the solution. Just need to write
'type' => 'category-select',
insted of
'type' => 'select',
