Hi jnwb,
Here’s the fix: (and an explanation)
In this case, the solution is actually in the error message. If we open up our file “class.widgets.php” which you can find by going toi the path dictated in the warning, we see the following on lines 109-137.
function ms_global_search_vertical_form( $page, $search_pages, $hide_options ) {
if( isset( $this ) ) {
$id_base = $this->id_base;
} else {
$id_base = 'ms-global-search';
}
$rand = rand(); $rand2 = $rand + 1; ?>
<form class="ms-global-search_form" method="get" action="<?php echo get_bloginfo( 'wpurl' ).'/'.$page.'/'; ?>">
<input id="s" class="field" name="mssearch" type="text" placeholder="Search across network sites:" size="16" tabindex="1" />
<input type="submit" id="searchsubmit" class="button submit" value="<?php _e( 'Search', 'ms-global-search' )?>" tabindex="2" />
</form>
<?php
}
function ms_global_search_horizontal_form( $page, $search_pages, $hide_options ) {
if( isset( $this ) ) {
$id_base = $this->id_base;
} else {
$id_base = 'ms-global-search';
}
$rand = rand(); ?>
<form class="ms-global-search_form" method="get" action="<?php echo get_bloginfo( 'wpurl' ).'/'.$page.'/'; ?>">
<input id="s" class="field" name="mssearch" type="text" placeholder="Search across network sites:" size="16" tabindex="1" />
<input type="submit" id="searchsubmit" class="button submit" value="<?php _e( 'Search', 'ms-global-search' )?>" tabindex="2" />
</form>
<?php
}
The above code might look a bit different than your own; I hacked the plugin and inserted the WordPress search form as the return for the search form instead of the multisite one, this way it styles the same in your CSS as it was intended in your theme.
These two functions are what control the php code that you called. ( <?php Multisite_Global_Search::ms_global_search_horizontal_form('search-results') ?> However, when you compare your php to the function that the php is calling, you might notice something odd.
Remember, this is what you put in:
<?php Multisite_Global_Search::ms_global_search_horizontal_form('search-results') ?>
and the function looks like this:
function ms_global_search_vertical_form( $page, $search_pages, $hide_options )
So what we have here is a line of PHP code that calls a function which demands $page, $search_pages, and $hide_options as input arguments, but in our code, we only provided one, “search-results” as our $page, hence the “missing argument on line 109”.
So to fix this, let’s provide the function in the “class.widgets.php” file with two additional arguments, whether we want to search pages, and whether we want to show the options.
My final markup looked like this:
<?php Multisite_Global_Search::ms_global_search_vertical_form('search-results','','hide_options'); ?>
Notice I left the $search_pages option blank. You can do this, and the plugin will default to a value of 0, and not search pages. If you would like to include pages in your search, set it to 1.
Kinda a long way around just for one line of code, but I hope the explanation was useful. If you have more questions, don’t hesitate to ask.
PS. I didn’t like how this plugin worked, there were a few quirks to get by. If you dig through the plugin files, you could figure out what everything does and hack it to your liking. After all that’s the purpose of plugins, right? Open source for the win.
Hope this helped,
Noel
