formmailer Posted October 25, 2011 Posted October 25, 2011 Hi, I am trying to create a simple search form with drop downs, just like the search on the skyscraper demo site. I know that the selectors should look something like this: $pages->find("template=citytrips, limit=10, price>=250, price<=400, transportation=airplane, touroperator=xxx inc."); but I can't really figure out how to use this in a search template. Therefore I would like to ask Ryan if it's possible to take a look at the source files of the demo site, so I can learn from these? Of course, all other tips and suggestions to achieve this fairly simple search are greatly appreciated. Thanks in advance! //Jasper
ryan Posted October 25, 2011 Posted October 25, 2011 Here's what draws the form for the skyscrapers search: <form id='skyscraper_search' method='get' action='<?php echo $config->urls->root?>search/'> <h3>Skyscraper Search</h3> <p> <label for='search_keywords'>Keywords</label> <input type='text' name='keywords' id='search_keywords' value='<?php if($input->whitelist->keywords) echo htmlentities($input->whitelist->keywords, ENT_QUOTES); ?>' /> </p> <p> <label for='search_city'>City</label> <select id='search_city' name='city'> <option value=''>Any</option> <?php // generate the city options, checking the whitelist to see if any are already selected foreach($pages->get("/cities/")->children() as $city) { $selected = $city->name == $input->whitelist->city ? " selected='selected' " : ''; echo "<option$selected value='{$city->name}'>{$city->title}</option>"; } ?> </select> </p> <p> <label for='search_height'>Height</label> <select id='search_height' name='height'> <option value=''>Any</option> <?php // generate a range of heights, checking our whitelist to see if any are already selected foreach(array('0-250', '250-500', '500-750', '750-1000', '1000+') as $range) { $selected = $range == $input->whitelist->height ? " selected='selected'" : ''; echo "<option$selected value='$range'>$range ft.</option>"; } ?> </select> </p> <p> <label for='search_floors'>Floors</label> <select id='search_floors' name='floors'> <option value=''>Any</option> <?php // generate our range of floors, checking to see if any are already selected foreach(array('1-20', '20-40', '40-60', '60-80', '80+') as $range) { $selected = $range == $input->whitelist->floors ? " selected='selected'" : ''; echo "<option$selected value='$range'>$range floors</option>"; } ?> </select> </p> <p> <label for='search_year'>Year</label> <select id='search_year' name='year'> <option value=''>Any</option> <?php // generate a range of years by decade, checking to see if any are selected for($year = 1850; $year <= 2010; $year += 10){ $endYear = $year+9; $range = "$year-$endYear"; $selected = $input->whitelist->year == $range ? " selected='selected'" : ''; echo "<option$selected value='$range'>{$year}s</option>"; } ?> </select> </p> <p><input type='submit' id='search_submit' name='submit' value='Search' /></p> </form> And here's the code that processes it and performs the search: <?php /** * This template looks for search terms as GET vars and formulates a selector to find matching skyscrapers * */ // most of the code in this template file is here to build this selector string // it will contain the search query that gets sent to $skyscraperList $selector = ''; // we use this to store the info that generates the summary of what was searched for // the summary will appear above the search results $summary = array( "city" => "", "height" => "", "floors" => "", "year" => "", "keywords" => "", ); // if a city is specified, then we limit the results to having that city as their parent if($input->get->city) { $city = $pages->get("/cities/" . $sanitizer->pageName($input->get->city)); if($city) { $selector .= "parent=$city, "; $summary["city"] = $city->title; $input->whitelist('city', $city->name); } } // we are allowing these GET vars in the format of 999, 999-9999, or 999+ // so we're using this loop to parse them into a selector foreach(array('height', 'floors', 'year') as $key) { if(!$value = $input->get->$key) continue; // see if the value is given as a range (i.e. two numbers separated by a dash) if(strpos($value, '-') !== false) { list($min, $max) = explode('-', $value); $min = (int) $min; $max = (int) $max; $selector .= "$key>=$min, $key<=$max, "; $summary[$key] = (substr($max, 0, 3) == '999') ? "$min and above" : "$min to $max"; $input->whitelist($key, "$min-$max"); // see if the value ends with a +, which we used to indicate 'greater than or equal to' } else if(substr($value, -1) == '+') { $value = (int) $value; $selector .= "$key>=$value, "; $summary[$key] = "$value and above"; $input->whitelist($key, "$value+"); // plain value that doesn't need further parsing } else { $value = (int) $value; $selector .= "$key=$value, "; $summary[$key] = $value; $input->whitelist($key, $value); } } // if there are keywords, look in the title and body fields for the words. Note in our selector // we are using the "~=" operator, rather than the "*=" operator, which means that we want to // match all the words, but they don't have to be in a phrase right next to each other. if($input->get->keywords) { $value = $sanitizer->selectorValue($input->get->keywords); $selector .= "title|body~=$value, "; $summary["keywords"] = htmlentities($value); $input->whitelist('keywords', $value); } // display a summary of what was searched for above the search results $content = "<ul id='search_summary'>"; $browserTitle = "Skyscrapers - "; foreach($summary as $key => $value) { if(!$value) continue; $key = ucfirst($key); $content .= "\n\t<li><strong>$key:</strong> $value</li>"; $browserTitle .= "$key: $value, "; } $content .= "\n</ul>"; $skyscrapers = $pages->find($selector); $content .= $skyscrapers->render(); // substitute your own output code $browserTitle = rtrim($browserTitle, ", "); $headline = "Skyscraper Search"; include("./main.php"); 1 1
formmailer Posted October 26, 2011 Author Posted October 26, 2011 Thanks Ryan! I think this covers most (if not all) of my needs right now. /Jasper
formmailer Posted November 4, 2011 Author Posted November 4, 2011 Now I just have one issue left regarding this "simple" search... How can I populate my dropdown with touroperators? I can't do it the same way Ryan did with the cities, because there are no seperate branches in the tree for all touroperators. As it is now, touroperaror is just a textfield in the "citytrip-template". Any suggestions? /Jasper
Pete Posted November 4, 2011 Posted November 4, 2011 You should be able to do something like this to get an array containing your tour operators: $touroperators = $fields->find("touroperator"); A similar example is on this page: http://processwire.com/api/selectors/ Basically you can use "find" on pretty much anything - templates, fields, users and pages by prefixing find with the object you're looking for.
formmailer Posted November 4, 2011 Author Posted November 4, 2011 Thanks! I still have some problems to come up with things like that myself, but I am sure I'll learn it one day... /Jasper
