WordPress: register_settings helper -

-

im trying make register_settings little bit cleaner plugin. looks way:

add_action( 'admin_init', 'hpblogposts_register_settings' ); function hpblogposts_register_settings() {     register_setting( 'hpblogposts_settings_options_group', 'linkid01' );     register_setting( 'hpblogposts_settings_options_group', 'linktext01' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt01' );     register_setting( 'hpblogposts_settings_options_group', 'linkid02' );     register_setting( 'hpblogposts_settings_options_group', 'linktext02' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt02' );     register_setting( 'hpblogposts_settings_options_group', 'linkid03' );     register_setting( 'hpblogposts_settings_options_group', 'linktext03' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt03' );     register_setting( 'hpblogposts_settings_options_group', 'linkid04' );     register_setting( 'hpblogposts_settings_options_group', 'linktext04' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt04' );     register_setting( 'hpblogposts_settings_options_group', 'linkid05' );     register_setting( 'hpblogposts_settings_options_group', 'linktext05' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt05' );     register_setting( 'hpblogposts_settings_options_group', 'linkid06' );     register_setting( 'hpblogposts_settings_options_group', 'linktext06' );     register_setting( 'hpblogposts_settings_options_group', 'linkalt06' ); }

for each "group" of settings register_settings called 3 times. trying make easier:

add_action( 'admin_init', 'hpblogposts_register_settings' ); function cshpblogpostssimplyregistersettings($id) {     register_setting( 'hpblogposts_settings_options_group', 'linkid'+$id );     register_setting( 'hpblogposts_settings_options_group', 'linktext'+$id );     register_setting( 'hpblogposts_settings_options_group', 'linkalt'+$id ); } function hpblogposts_register_settings() {     cshpblogpostssimplyregistersettings('01');     cshpblogpostssimplyregistersettings('02');     cshpblogpostssimplyregistersettings('03');     cshpblogpostssimplyregistersettings('04');     cshpblogpostssimplyregistersettings('05');     cshpblogpostssimplyregistersettings('06'); }

but doesnt work way (values not saved).

any idea have made mistake?

for one, when you're concatenating strings should use dot, not plus:

register_setting( 'hpblogposts_settings_options_group', 'linkalt' . $id );
