Multiple Category or Tag Search

Hi People,

I’m looking for a way to create a search feature which users can search KEYWORDS and select between multiple category’s.

I looked at WP Custom Search and it does work but does not work how I want it too. When I search for results it uses my Themes index.php which has a main image slider.

Anyways I have been trying to create a form in which I can use keywords a category and then tags. But just don’t have the knowledge to complete it.

I have this in a searchform.php

<form action="<?php bloginfo('template_url') ?>/build_search.php" method="post" accept-charset="utf-8">
	<div>Search</div>
	<input type="text" name="keywordsearch" value="" id="title">

	<div>Category</div>
	<?php wp_dropdown_categories( 'child_of=4' ); ?>

	<div>Tags</div>
	<select name="and-or" id="select-and-or">
		<option value="OR">Match ANY of the checkboxes (default)</option>
		<option value="AND">Match ALL of the checkboxes</option>
	</select>
	<div>
		<?php
		// The following will list all tags with a checkbox next to them.
		$tags = get_terms( 'post_tag' );
		$checkboxes = '';
		foreach($tags as $tag) :
			$checkboxes .='<input type="checkbox" name="tag[]" value="'.$tag -> slug.'" id="tag-'.$tag->term_id.'" /><label for="tag-'.$tag->term_id.'">'.$tag->name.'</label>';
		endforeach;
		print $checkboxes;
		?>
	</div>
	<p><input type="submit" value="Search"></p>
</form>

This then uses the build_search.php

<?php

	//	Keyword search
	if (isset($_POST['keywordsearch'])) {
        $text_search = $_POST['keywordsearch'];
        $text = $text_search;
	}

	//	If there is no keyword entered
	else {
        $text = '';
	}

	//	If there's a category search
	if (isset($_POST["cat"])) {
		$cat = $_POST["cat"];
	}

	// If there's a tag search
	if (isset($_POST["tag"])){
		$tags_array = array();
		$tags_array = $_POST["tag"];

		foreach ($tags_array as $key => $value)
		{
			if ($_POST["and-or"] == "OR") {
				//	tag1 OR tag2 is chosen, add a comma after the tags
				$string .= $value.',';
			}
			elseif ($_POST["and-or"] == "AND") {
				//	tag1 AND tag2 is chosen, add a plus after the tags.
				$string .= $value.'+';
			}
		}

		// Remove the last symbol in the string, in this case the comma or plus that is added after each tag. We don't want it to look like "tag1+tag2+".
		$tags_string = substr($string, 0, -1);

			$tag = $tags_string;
	}

	//	If there's no search for tags, set it to 0
	else {
		$tag = 0;
	}

	// build the url with the variables
	$url = header("Location:/am2pm/?s=$text&cat=$cat&tag=$tag");
?>

The code takes what you have entered and changes the URL.

For my search page I just use the normal <?php get_search_form(); ?> which directs to the first search form.

This coding was found on a older post and seems to work, just the keywords do not work.

This is the closest I have got to what I want and WP Custom Search.

Im looking to have:

KEYWORDS ….

Location ….

Job Type ….

If anyone has any help or idea then I would be grateful.￡
