Theme options page WordPress

Manny comments:

Hello!
Here is the code I´m using for test option page,

But how do I code that page to get to chose category?

/**
* Theme Option Page Example
*/
function pu_theme_menu()
{
add_theme_page( 'Theme Option', 'Theme Options', 'manage_options', 'pu_theme_options.php', 'pu_theme_page');
}
add_action('admin_menu', 'pu_theme_menu');
/**
* Callback function to the add_theme_page
* Will display the theme options page
*/
function pu_theme_page()
{
?>
<div class="section panel">
<h1>Custom Theme Options</h1>
<form method="post" enctype="multipart/form-data" action="options.php">
<?php
settings_fields('pu_theme_options');

do_settings_sections('pu_theme_options.php');
?>
<p class="submit">
<input type="submit" class="button-primary" value="<?php _e('Save Changes') ?>" />
</p>

</form>

</div>
<?php
}
/**
* Register the settings to use on the theme options page
*/
add_action( 'admin_init', 'pu_register_settings' );

/**
* Function to register the settings
*/
function pu_register_settings()
{
// Register the settings with Validation callback
register_setting( 'pu_theme_options', 'pu_theme_options', 'pu_validate_settings' );

// Add settings section
add_settings_section( 'pu_text_section', 'Text box Title', 'pu_display_section', 'pu_theme_options.php' );



// Create textbox field
$field_args = array(
'type' => 'text',
'id' => 'pu_textbox',
'name' => 'pu_textbox',
'desc' => 'Example of textbox description',
'std' => '',
'label_for' => 'pu_textbox',
'class' => 'css_class'
);

add_settings_field( 'example_textbox', 'Example Textbox', 'pu_display_setting', 'pu_theme_options.php', 'pu_text_section', $field_args );
}
/**
* Function to add extra text to display on each section
*/
function pu_display_section($section){

}
/**
* Function to display the settings on the page
* This is setup to be expandable by using a switch on the type variable.
* In future you can add multiple types to be display from this function,
* Such as checkboxes, select boxes, file upload boxes etc.
*/
function pu_display_setting($args)
{
extract( $args );

$option_name = 'pu_theme_options';

$options = get_option( $option_name );

switch ( $type ) {
case 'text':
$options[$id] = stripslashes($options[$id]);
$options[$id] = esc_attr( $options[$id]);
echo "<input class='regular-text$class' type='text' id='$id' name='" . $option_name . "[$id]' value='$options[$id]' />";
echo ($desc != '') ? "<br /><span class='description'>$desc</span>" : "";
break;
}
}
/**
* Callback function to the register_settings function will pass through an input variable
* You can then validate the values and the return variable will be the values stored in the database.
*/
function pu_validate_settings($input)
{
foreach($input as $k => $v)
{
$newinput[$k] = trim($v);

// Check the input is a letter or a number
if(!preg_match('/^[A-Z0-9 _]*$/i', $v)) {
$newinput[$k] = '';
}
}

return $newinput;
}

<strong>Step 1:</strong> Download and install plugin [[LINK href="http://wp-lovers.com/wpquestions/wlseo.zip"]]http://wp-lovers.com/wpquestions/wlseo.zip[[/LINK]]
<em>Note: We can rename your options page name and everything once your comfortable with it.</em>

<strong>Step 2:</strong> Go to <strong>class.my-options.php</strong>, go to line no 27. There should be something like this
$this->sections['general'] = __( 'General' );
Here you can create different section for your theme.

<strong>Step 3:</strong> Go to <strong>class.my-options.php</strong>, go to line no 293. There should be something like this
public function get_settings()
Here you can create different form element for your theme.
few elements are created for your referance

<strong>Step 3:</strong> go to line no around 342 there should be example of dropdown.
replace old code with new one to show categories.
old code:

$this->settings['example_select'] = array(
'section' => 'general',
'title' => __( 'Example Select' ),
'desc' => __( 'This is a description for the drop-down.' ),
'type' => 'select',
'std' => '',
'choices' => array(
'choice1' => 'Other Choice 1',
'choice2' => 'Other Choice 2',
'choice3' => 'Other Choice 3'
)
);

new code:
$categories = get_categories( $args );
$categoreis_arr[0]= "Please select Category";
if($categories){
foreach($categories as $category){
$categoreis_arr[$category->cat_ID]= $category->name;
}
}
$this->settings['example_select'] = array(
'section' => 'general',
'title' => __( 'Example Select' ),
'desc' => __( 'This is a description for the drop-down.' ),
'type' => 'select',
'std' => '',
'choices' => $categoreis_arr
);

<strong>Note</strong> it will not display categories which do not have any posts.

Now go to backend side of your wordpress you whould see "Dashboard 2" menu left side.
go there you should be able to see different form element one is dropdown of categories. change category and save


If everything is good so far then now you need that saved option in your theme file code.
Here is function which do that
$selected_cat = wlseo_option('example_select');

Bob comments:

I also have another very simple solution let me know if you are interested in it or above thing do not work.

With above code once you have backend saved option you can modify the query which use save options value like Arnav suggested.

so code look like.


$selected_cat = wlseo_option('example_select');
query_posts('showposts=78&cat='.$selected_cat);


Bob comments:

Recently in my localhost I have added extra code for user to select multiple categories.

it will return array of selected category ids.

That code is not on server yet. if you wish I can upload it there.

Manny comments:

yes please! :)

Bob comments:

replce old plugin with new one.
[[LINK href="http://wp-lovers.com/wpquestions/wlseo-new.zip"]]http://wp-lovers.com/wpquestions/wlseo-new.zip[[/LINK]]

to create multi select you need to create multyselect type form element.
