I am attempting to automate, as much as possible, the Settings API function calls for each setting in a Plugin. Looping through the options array, and outputting add_settings_section()
and add_settings_field()
is simple enough:
add_settings_section()
:
$oenology_hooks_tabs = oenology_hooks_get_settings_page_tabs();
foreach ( $oenology_hooks_tabs as $tab ) {
$tabname = $tab['name'];
$tabtitle = $tab['title'];
$tabsections = $tab['sections'];
foreach ( $tabsections as $section ) {
$sectionname = $section['name'];
$sectiontitle = $section['title'];
$sectiondescription = $section['description'];
// Add settings section
add_settings_section(
'oenology_hooks_' . $sectionname . '_section',
$sectiontitle,
'oenology_hooks_' . $sectionname . '_text',
'oenology_hooks_' . $tabname . '_tab'
);
}
}
And `add_settings_field():
global $oenology_hooks;
$oenology_hooks = oenology_hooks_get_hooks();
foreach ( $oenology_hooks as $hook ) {
$hookname = $hook['name'];
$hooktitle = $hook['title'];
$hooktab = $hook['tab'];
$hooksection = $hook['section'];
add_settings_field(
'oenology_hooks_' . $hookname,
$hooktitle,
'oenology_hooks_setting_callback',
'oenology_hooks_' . $hooktab . '_tab',
'oenology_hooks_' . $hooksection . '_section',
$hook
);
}
With add_settings_field()
, I can easily write a generic callback, by passing the $hook
variable to the callback, as the fifth parameter in the function call:
function oenology_hooks_setting_callback( $hook ) {
$oenology_hooks_options = get_option( 'plugin_oenology_hooks_settings' );
$hookname = $hook['name'];
$hooktitle = $hook['title'];
$hookdescription = $hook['description'];
$hooktype = $hook['type'];
$hooktab = $hook['tab'];
$hooksection = $hook['section'];
$inputvalue = $hookname . '_hide';
$inputname="plugin_oenology_hooks_settings[" . $inputvalue . ']';
$textareaname="plugin_oenology_hooks_settings[" . $hookname . ']';
$textareavalue = $oenology_hooks_options[$hookname];
if ( 'Filter' == $hooktype ) {
?>
<input type="checkbox" name="<?php echo $inputname; ?>" value="<?php echo $inputvalue;?>" <?php checked( true == $oenology_hooks_options[$inputvalue] ); ?> />
<span>Hide <?php echo $hooktitle; ?> content?</span><br />
<?php
}
?>
<span class="description"><?php echo $hooktype; ?> Hook: <?php echo $hookdescription; ?></span><br />
<textarea name="<?php echo $textareaname; ?>" cols="80" rows="3" ><?php
echo esc_textarea( $textareavalue );
?></textarea>
<?php
}
However, it appears that add_settings_section()
does not have an analogous $args
parameter; thus, I cannot use the same method to pass the $section
variable to the callback.
Thus, my question: is there any way to pass a variable to the add_settings_section()
callback, or some other way to create a callback analogous to what I’m doing for add_settings_field()
?
EDIT:
@Bainternet nailed it! Here’s my working code:
/**
* Callback for add_settings_section()
*
* Generic callback to output the section text
* for each Plugin settings section.
*
* @param array $section_passed Array passed from add_settings_section()
*/
function oenology_hooks_sections_callback( $section_passed ) {
global $oenology_hooks_tabs;
$oenology_hooks_tabs = oenology_hooks_get_settings_page_tabs();
foreach ( $oenology_hooks_tabs as $tab ) {
$tabname = $tab['name'];
$tabsections = $tab['sections'];
foreach ( $tabsections as $section ) {
$sectionname = $section['name'];
$sectiondescription = $section['description'];
$section_callback_id = 'oenology_hooks_' . $sectionname . '_section';
if ( $section_callback_id == $section_passed['id'] ) {
?>
<p><?php echo $sectiondescription; ?></p>
<?php
}
}
}
}
if you look at the do_settings_sections function more specifically the line 1164 where the callback function is being executed :
call_user_func($section['callback'], $section);
you can see that the $section array is being passed to the callback function, so you can identify the callback by the $section['id']
hope this make since.
Update
here is an example, if your add_settings_section callback for all sections was named oenology_hooks_section_callback
then you can identify it like this:
function oenology_hooks_section_callback($section_passed){
if ($section_passed['id'] == 'whatever_section_id'){
//do stuff
}
if ($section_passed['id'] == 'whatever_section_id_number2'){
//do other stuff
}
}
and by do stuff i mean do whatever you want to do with that section callback.
