How To Save Settings and Call That Value Again?

wgn_white · Nov 30, 2009

Hello to all.

I need help.

I'm making a wordpress theme with some admin interface.
My mission is towards "No Hand Code For User".

After reading the WordPress codex about a week ago, I manage to register my admin page under the Appearance tab which what I want.

Now I want to put form in that page which I already know how to and yes, the form appear at that page. But I don't know where to save that options and how to call back the value of the option.

My goal is to make css selector for my users.

This is how I do it so far.

I put all the css files inside one directory and using scandir and readdir, I manage to display the css filename in <option> by using a loop.

What I want, when the users select which css file name and the click save, that file name will be saved.

And then, I will need to call the chosen filename again and then use add_action to hook it to <head> so it will import the css.

Am I making myself clear?

Please enlighten me, I have read the WordPress codex and still don't get it, and I don't have formal lesson on PHP and mySQL database. I'm just enthusiast.

Best regards,
wgn_white

Use update_option function

For example

Code:

$css_filename = 'css_file';
$css_filename_value = 'style1.css';
update_option($css_filename,$css_filename_value);

The code above would save the filename or update it if it is already present. Makesure $css_filename is unique and will not conflict with any wordpress options

And to read the option

Code:

$css_file = get_option($css_filename);

Hope that was clear.

Alright, I'm trying to implement it now.

Hey, guys.

I manage to save the setting value and also being able to call the value.
Thank you for the reply.

But I have another problem.

I get this error,

Code:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampplite\htdocs\wordpress\wp-content\themes\wpthemestudiox2\wptsx2-includes\colour-switcher.php:12) in C:\xampplite\htdocs\wordpress\wp-includes\pluggable.php on line 865

After the submit form being submit.

I know some of you might say that delete whitespace, etc.
Cannot find anything such as, I'm using dreamweaver cs3.

Here's the code of the functions.

Code:

if ( is_admin() ){

	add_action('admin_init', 'wptsx2_register_colourswitcher_settings');
	add_action('admin_menu', 'wptsx2_admin_reg');

}

else {

	// Nothing. Really.

}

function wptsx2_admin_reg() {

	add_submenu_page('themes.php', 'WPThemestudio X2 Administration', 'WPTS X2', 'administrator', 'wptsx2-admin/admin-page.php', 'wptsx2_admin_page');

}

Code:

<?php function wptsx2_admin_page() { ?>

		</p>
	</div>
	
</form>

<?php }

function the_colour() {

	if(get_option('wptsx2_colourfile') == FALSE) { ?>

		<link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/wptsx2-themes/default-colour.css" type="text/css" media="screen" />
	
	<?php }
	
	else { ?>
	
		<link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/wptsx2-themes/<?php echo get_option('wptsx2_colourfile'); ?>" type="text/css" media="screen" />
	
	<?php }
} ?>

Thank you very much.

You are sending stuff that should be in the header after the

Code:

</head>

tag.

From your code the likely culprit are the

Code:

<link>

tags in the function the_colour().

That function should be called before the header tag is closed. I don't see the point at which you are calling this function. You are probably doing it in another file at the wrong location.

You should use a wordpress hook to call the_colour() at the right time.
This may be the right place to do it

Code:

if ( is_admin() ){

    add_action('admin_init', 'wptsx2_register_colourswitcher_settings');
    add_action('admin_menu', 'wptsx2_admin_reg');

}

else {

    // Nothing. Really.

}
[COLOR=DeepSkyBlue]
add_action('wp_head', 'the_colour');[/COLOR]

function wptsx2_admin_reg() {

    add_submenu_page('themes.php', 'WPThemestudio X2 Administration', 'WPTS X2', 'administrator', 'wptsx2-admin/admin-page.php', 'wptsx2_admin_page');

}

@BozoClown

Yes, I put the add_action in other files called actions.php where all actions were execute.

I've tried your suggested solution... It still doesn't resolve the issue.

The warning appear each time I save the form.
But the form manage to save the value into the database.

I use register_settings to make my form.
Ah, I really don't want to use those array method to make my form...
