Notice: Undefined index: id in…

Paul Cracknell — Thu, 20 Jan 2011 02:05:48 +0000

If you are developing a WordPress Theme Option Page via some tutorials on the web, the php that is used to call the options will create these errors when the WordPress debug feature is activated.
Notice: Undefined index: id in C:\Users\Mysql folder\root\wordpress\wp-content\themes\breathe\index.php on line 4

Notice: Undefined index: std in C:\Users\Mysql folder\root\wordpress\wp-content\themes\breathe\index.php on line 4

The code that is generally outlined and is the culprit for the errors is…


global $options;
foreach ($options as $value) {
    if (get_option( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; }
	else { $$value['id'] = get_option( $value['id'] ); }
}
?>

To fix the problem I have found that this piece of code will eliminate the errors.


//allows the theme to get info from the theme options page
global $options;
foreach ($options as $value) {
	if ( isset( $value['id'] ) ) {
		if (get_option( $value['id'] ) === FALSE) {
			$$value['id'] = $value['std'];
		} else {
			$$value['id'] = get_option( $value['id'] );
		}
	}
}
?>

Debug your WordPress Theme

So you have finished your WordPress theme and now you want to check that everything that you have done is right. Debugging the php is just one of the steps that you should take to check that your theme is ready to unleash on the world. It is very simple to activate the de-bugging feature for WordPress. In the root directory of your theme find wp-config.php. Open the file and locate this code.

/** * For developers: WordPress debugging mode. * * Change this to true to enable the display of notices during development. * It is strongly recommended that plugin and theme developers use WP_DEBUG * in their development environments. */ define('WP_DEBUG', false);

See it even tells you that this is for debugging. As advised make sure that plugin’s are deactivated. Change false to true and save the file. Upload it to the theme and any errors will be displayed where the errors are detected. When you are finished and before you publish your theme turn the debug off.

It is also good practice to check your html (xhtml) and css with a validator service, these can be located at http://validator.w3.org/ orhttp://jigsaw.w3.org/css-validator/ respectively.

How to fix errors with uploading images or media in WordPress

Paul Cracknell — Wed, 13 May 2009 09:47:26 +0000

If you are having trouble uploading images because of this error: File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini when you use either the flash uploader or the browser, there is fix. A short article by Phillip Barron outlines a fix using the .htaccess file.

Step 1

Using your FTP open the root directory. Download .htaccess and open it with

text editor or notepad. It should be just below the folders. If there isn’t a .

htaccess file, create one.

Step 2

Insert the following into your .htaccess file. If there is other commands which there most likely will be just under that is fine.


SetEnvIfNoCase Content-Type
"^multipart/form-data;" "MODSEC_NOPOSTBUFFERING=Do not buffer file uploads"



mod_gzip_on No

Step 3

Save and upload the .htaccess file back into the root directory overwriting the original.

Result: Image upload should be successfully using Firefox/Windows with no errors.
