  1. Hello Soma, thank you for this useful module. I like it very much and use it in a few projects. I think I found a little bug. Line 65 in FieldtypeColorPicker.module says if($value == "0") $value = "00000"; One 0 is missing, so it outputs #00000 in case of black. Most Browsers ignore that, I think, instead of interpreting it as black. Greetings
  2. Hello, I tried to install nico's module Page Delete ( http://modules.processwire.com/modules/process-page-delete/ ) and get the following error: I've no idea what this means. I use the useful module with some other ProcessWire installations on the same server and never had this problem. Can you help me? Thanks in advance
  3. Thanks again for your answers. I tried diogo's idea and used if($pages->get("parent=$tour, name=$concert->name, fotos.count>0")->id) as condition. It's really much faster. Time for rendering reduced from average 4.89sec to 1.49sec. Good idea. Thank you. I will also try Soma's approach of caching the number of images via an extra field. Sounds promising, too. Thank you. In this project, I don't want to change the hierarchy because the customer is used to it now and works well with it. But in the near future I have a project, a website for a theater, with more complex dependencies where I will learn to work with page selectors. Currently I am totally satisfied with the solution of simply turning on ProcessWire's caching function. Nevertheless I want to write efficient code, so I drew up this topic. Thank you all for your time.
  4. Thanks a lot for your answers. Meanwhile I found out, that the most expensive line is if(count($concert->fotos) > 0)... Without it, the page renders in exeptable time. Is there a more efficient way to find out, if an image field contains at least one image? I tried if($concert->fotos->first()), but there was no noticeable difference. Not using two nested foreach-loops leads to another problem. The list should be interrupted by a headline when a new tour begins. (My fault, I deleted most of the markup for better legibility.) <?php foreach($tours->children as $tour) { ?> <h1><?=$tour->title?></h1> <ul> <?php foreach($tour->children as $concert) { ?> <li><?=$concert->date?>, <?=$concert->title?>, <?=$concert->city?> <?php // Check for content, then show the icon if($concert->text) { echo '<img src="'.$config->urls->templates.'styles/images/icon_text.png" alt="Konzertbericht" />'; } if(count($concert->fotos) > 0) { echo '<img src="'.$config->urls->templates.'styles/images/icon_photos.png" alt="Fotos" />'; } if($concert->podcast) { echo '<img src="'.$config->urls->templates.'styles/images/icon_video.png" alt="Podcast" />'; } ?> </li> <?php } // END foreach($tour->children as $concert) ?> </ul> <?php } // END foreach($tours->children as $tour) ?> Without nested loops I would have to do something like this: $concerts = $pages->find('template=concert, sort=-date'); echo "<h1>$concerts->first()->parent->title</h1><ul>"; $prev = $concerts->first(); foreach($concerts as $concert) { if($concert->parent->title != $prev->parent->title) { echo "</ul><h1>$concert->parent->title</h1><ul>"; } // print concert $prev = $concert; } echo "</ul>"; I think that would make it even worse.
  5. Hello ProcessWire community, as this is my first posting, I want to thank Ryan Cramer and the ProcessWire community for developing such a great software. ProcessWire is the first CMS that fits my needs perfectly and it's a pleasure to work with it. (Also thanks to isellsoap for recommending it to me.) So here's my first question: The website of a band has a kind of a diary. The children of "diary" have the template "tour" and the children of "tour" have the template "concert". "concert" has (beside others) a textarea field for the report, an image field for photos and a text field to embed a youtube video. None is required. An overview page should show a list of all concerts. If a field of the concert (report, photos, video) has content, a specific icon shall be shown. Everything works fine so far, but it takes about 5 seconds to render the page with about 250 concerts in the list. Currently I solve this by simply turn on the caching, but I think 5 seconds to list 250 pages is a bit too long. (What if I had to deal with 10000 pages or more?) It runs on a virtual server with at least 1 GHz CPU and 2 Gbyte RAM. Below is my code (a little shortened). Has somebody an idea, which could be the inefficient part? Thank you in advance. <ul> <?php foreach($tours->children as $tour) { foreach($tour->children as $concert) { ?> <li><?=$concert->date?>, <?=$concert->title?>, <?=$concert->city?> <?php // Check for content, then show the icon if($concert->text) { echo '<img src="'.$config->urls->templates.'styles/images/icon_text.png" alt="Konzertbericht" />'; } if(count($concert->fotos) > 0) { echo '<img src="'.$config->urls->templates.'styles/images/icon_photos.png" alt="Fotos" />'; } if($concert->podcast) { echo '<img src="'.$config->urls->templates.'styles/images/icon_video.png" alt="Podcast" />'; } ?> </li> <?php } // END foreach($tour->children as $concert) ?> <?php } // END foreach($tours->children as $tour) ?> </ul>
