I'll try to keep an eye on this thread for the next little while so let me know if you have any questions related to today.</p> <p>Take Aways from the Program<br /> - try a bit of everything, then start to specialize<br /> - develop a network of peers (learn from and push each other)<br /> - complete assignments and move on - each project will be better than the last<br /> - collaborate with those who have complimentary skills<br /> - think about design as problem-solving - have reasons for your decisions<br /> - practice with what's coming, what's established</p> <p>The Job Hunt<br /> - willingness and ability to learn more important than what you know (junior positions are all about your potential)<br /> - a network of peers is almost essential for getting your foot in the *right* door<br /> - be involved in the community (peers from school, local *Camps, Ignite Events, Refresh Events, FITC, NXNEi, Drupal Users Group, Twitter, Facebook, Dribbble, etc.)<br /> - tell people you're looking (keep yourself in their heads, use their networks too)<br /> - I don't recommend relying in freelance to pay the bills - at least not in the first year</p> <p>Day in the Life<br /> - "CMS Web Designer" at UofT - everything from one-page brochure-ware sites to large CMS sites for entire faculties, central university services.<br /> - design lead for projects: initial meeting, IA, design, theme coding, support<br /> - other team members dedicated to training, back-end development<br /> - ~150 clients and growing<br /> - ~12 projects on the go at any time<br /> - Proprietary enterprise CMS (.NET), WordPress 3 (PHP), Drupal 7 (PHP)<br /> - balance the needs of the client business (managing the site, required functionality), their users (IA/design), the budget ($5k-$30k for most websites, $5k-$100k for web apps), the timeline (2 weeks - 2 years)<br /> - HTML5, CSS3, jQuery, PHP<br /> - Photoshop, Coda, Firebug/Web Developer Toolkit, VMWare Fusion, IETester<br /> - Firefox, Safari, Chrome, IE 6/7/8/9</p> <p>- Workflow: Creative brief, kick-off meeting, information architecture, pen and paper sketches, wireframes, static mock-ups and/or web prototypes, design meeting, debugging, staging site, client training, content prep, documentation, final tweaks, content freeze, cross fingers, launch</p> <p>- Atmosphere: small team (4 people total), time management and independent work a must, teamwork also essential for some tasks, projects. Able to communicate with clients, both to guide them through the IA/content strategy as well as developing and defending designs</p> <p>- Enterprise CMS: Big sites (UofT sees 3,000,000 hits/day), many users (Faculty of Medicine = 200 active site users), fine control over user groups, rolls and workflows, fine control over media and other digital assets, professionally documented and supported, consistent user experience across multiple sites, lack agility, awkwardly integrates community features into an unrelated document management, event management or content management model, closed API (difficult to develop custom plugins/modules for, integrate with secure authorization, etc.)</p> <p>- Enterprise CMS (Part 2): Solve closed source problems by adopting an enterprise-worthy open source CMS (Drupal). Develop standardized UofT base template and best practices with UofT Drupal Users Group. Develop university-vetted custom modules for secure authentication, etc. For other projects that don't require an enterprise-level solution, WordPress is very agile (quick to set up, design/develop themes for, add content to and launch) and a popular solution.</p> <p>- Post-Recession: University environment is largely sheltered from the rest of the job market's difficulty. Many people go back to school during a recession - the university focused on promoting itself (promotion requires online presence, new websites, etc.).</p> <p>My (Hopefully) Useful Links<br /> - <a href="http://www.alistapart.com/" rel="nofollow">http://www.alistapart.com/</a> &lt;-- great articles<br /> - <a href="http://net.tutsplus.com/" rel="nofollow">http://net.tutsplus.com/</a> &lt;-- lots of tutorials, part of a network of sites<br /> - <a href="http://dribbble.com/" rel="nofollow">http://dribbble.com/</a> &lt;-- constant stream of design work<br /> - <a href="http://52weeksofux.com/" rel="nofollow">http://52weeksofux.com/</a> &lt;-- numerous lessons on user experience design<br /> - <a href="http://molecularvoices.molecular.com/standards/" rel="nofollow">http://molecularvoices.molecular.com/standards/</a> &lt;-- best practices guide<br /> - <a href="http://www.webmonkey.com/2010/02/information_architecture_tutorial/" rel="nofollow">http://www.webmonkey.com/2010/02/information_architecture_tutorial/</a> &lt;-- IA tutorial<br /> - <a href="http://dl.dropbox.com/u/1982509/creative%20brief.docx" rel="nofollow">http://dl.dropbox.com/u/1982509/creative%20brief.docx</a> &lt;-- my creative brief<br /> - <a href="http://wordpress.tv/category/how-to/" rel="nofollow">http://wordpress.tv/category/how-to/</a> &lt;-- WordPress video tutorials</p> <p>- Designing With Web Standards, 3rd Edition &lt;-- If you only buy one book, consider this one</p> <p>Interview questions: <a href="http://docs.google.com/present/view?id=dcxrv3q7_41dr5dktc4" rel="nofollow">http://docs.google.com/present/view?id=dcxrv3q7_41dr5dktc4</a> </p> http://forum.wddmportfolios.com/topic/need-a-regular-expression-for-a-username-check#post-615 Fri, 03 Dec 2010 11:57:47 +0000 francis.san.juan 615@http://forum.wddmportfolios.com/ <p>I'm creating form validation for a site registration form and I want to check that a person's username has the following conditions:</p> <p>- Must start with a letter (lower or uppercase, doesn't matter)<br /> - The rest of the username can contain upper/lowercase letters, or numbers, or underscores<br /> - Contains no quotes or special characters (except underscores)</p> <p>So far I'm using this code to check if username doesn't match the appropriate pattern required:</p> <pre><code>if ( preg_match("/^[a-zA-Z]\w/i", $username) == 0 )</code></pre> <p>I just wanted to verify that this regular expression and php code is correct.</p> <p>Thanks! </p> http://forum.wddmportfolios.com/topic/makepassword#post-614 Wed, 10 Nov 2010 13:10:28 +0000 wen.ni 614@http://forum.wddmportfolios.com/ <p>Create a random password. </p> <p>function MakePassword($length)<br /> {<br /> $pass = "";<br /> $chars = array(<br /> "1","2","3","4","5","6","7","8","9","0",<br /> "a","A","b","B","c","C","d","D","e","E","f","F","g","G","h","H","i","I","j","J",<br /> "k","K","l","L","m","M","n","N","o","O","p","P","q","Q","r","R","s","S","t","T",<br /> "u","U","v","V","w","W","x","X","y","Y","z","Z");</p> <p> $count = count($chars) - 1;</p> <p> srand((double)microtime()*1000000);</p> <p> for($i = 0; $i &lt; $length; $i++)<br /> {<br /> $pass .= $chars[rand(0, $count)];<br /> }</p> <p> return($pass);<br /> } </p> http://forum.wddmportfolios.com/topic/get-remote-ip-address-in-php#post-613 Wed, 10 Nov 2010 12:04:29 +0000 mark.watson 613@http://forum.wddmportfolios.com/ <p>The above code will not work in case your client is behind proxy server.

The following code will go in a file called "switcher.php":</p> <pre><code>&lt;?php setcookie (&#39;sitestyle&#39;, $set, time()+31536000, &#39;/&#39;, &#39;yourdomain.com&#39;, &#39;0&#39;); header(&quot;Location: $HTTP_REFERER&quot;); ?&gt;</code></pre> <p>When the user selects an alternate stylesheet, this code will write a cookie that will keep the selected 'sitestyle' (the alternate stylesheet) in memory for a year.</p> <p>The second part that allows this script to work occurs on the PHP content page.</p> <p>In the &lt;head&gt; section, write your stylesheet link as follows:</p> <pre><code>&lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;screen&quot; title=&quot;User Defined Style&quot; href=&quot;&lt;?php echo (!$sitestyle)?&#39;defaultstyle&#39;:$sitestyle ?&gt;.css&quot; /&gt;</code></pre> <p>Then make a link somewhere in the &lt;body&gt; section that allows them to switch to an alternate style, such as this:</p> <pre><code>&lt;a href=&quot;./switcher.php?set=red&quot;&gt; click here to change to RED style!&lt;/a&gt;</code></pre> <p>What this does is calls on switcher.php to set the $sitestyle variable in the link tag to the name specified in the link. If they haven't selected an alternate style, the stylesheet called "defaultstyle.css" will be used by default. </p> http://forum.wddmportfolios.com/topic/making-thumbnails-for-a-directory-of-jpegs#post-602 Wed, 10 Nov 2010 09:21:41 +0000 shannon.maguire 602@http://forum.wddmportfolios.com/ <p>This will make thumbnails for an entire directory of jpeg images.</p> <p><code><br /> &lt;?php</p> <p>$images = new Imagick(glob('images/*.JPG'));</p> <p>foreach($images as $image) {</p> <p> // Providing 0 forces thumbnailImage to maintain aspect ratio<br /> $image-&gt;thumbnailImage(1024,0);</p> <p>}</p> <p>$images-&gt;writeImages();</p> <p>?&gt;<br /> </code> </p> http://forum.wddmportfolios.com/topic/seconds-to-string#post-601 Wed, 10 Nov 2010 09:18:57 +0000 mark.pancorvo 601@http://forum.wddmportfolios.com/ <p>This function will return the duration of the given time period in days, hours, minutes and seconds.</p> <p>e.g. secsToStr(1234567) would return "14 days, 6 hours, 56 minutes, 7 seconds"</p> <p><code><br /> function secsToStr($secs) {<br /> if($secs&gt;=86400){$days=floor($secs/86400);$secs=$secs%86400;$r=$days.' day';if($days&lt;&gt;1){$r.='s';}if($secs&gt;0){$r.=', ';}}<br /> if($secs&gt;=3600){$hours=floor($secs/3600);$secs=$secs%3600;$r.=$hours.' hour';if($hours&lt;&gt;1){$r.='s';}if($secs&gt;0){$r.=', ';}}<br /> if($secs&gt;=60){$minutes=floor($secs/60);$secs=$secs%60;$r.=$minutes.' minute';if($minutes&lt;&gt;1){$r.='s';}if($secs&gt;0){$r.=', ';}}<br /> $r.=$secs.' second';if($secs&lt;&gt;1){$r.='s';}<br /> return $r;<br /> }<br /> </code> </p> http://forum.wddmportfolios.com/topic/say-hello-and-write-a-test-post#post-23 Thu, 27 Aug 2009 01:05:23 +0000 thomas.borzecki 23@http://forum.wddmportfolios.com/ <p>Hi Everyone,<br /> I created this topic so that you could come and say hi, chat, swap info, and test out the posting system without messing up other topics. </p> http://forum.wddmportfolios.com/topic/unzip-files-with-php#post-599 Wed, 10 Nov 2010 09:16:47 +0000 szabi.apro 599@http://forum.wddmportfolios.com/ <p>Make sure you have the ZZIPlib library installed.

To clarify: VB’s Instr function will actually return either a 0 or the <em>position</em> of the search string if it is successful.

Single-quoted strings are stored as a literal translation - meaning what you see is what you get. Variables enclosed in double-quotes will be have their value used.</p> <p>Example:<br /> <pre><code>$year = 2010; $answer1 = &quot;$year&quot;; $answer2 = &#39;$year&#39;; echo $answer1; echo $answer2;</code></pre> <p>The result would be:<br /> <pre><code>2010 &#39;$year&#39;</code></pre> <p>The same is true when you have quotes that enclose an entire string - the outer quotes determine how the string is treated, even if you have other quotes inside that string.</p> <p>Example:<br /> <pre><code>$year = 2010; $statement1 = &quot;The year is &#39;$year &#39;.&quot;; $statement2 = &#39;The year is &quot; $year&quot;.&#39;; echo $statement1; echo $statement2;</code></pre> <p>The result would be:<br /> <pre><code>The year is &#39;2010&#39;. The year is &quot;$year&quot;.</code></pre> <p>Remember - the exception to the quote rule in strings is the use of the backslash in front of the quote \' or \" (which we all ready know means to ignore the succeeding quote). </p> http://forum.wddmportfolios.com/topic/using-the-glob-function-to-find-files#post-594 Tue, 09 Nov 2010 23:08:17 +0000 graine.wightman 594@http://forum.wddmportfolios.com/ <p>Somewhat similar to the scandir() function, the glob() function allows you to search for files matching a specified pattern and returns an array of filenames or directories:</p> <pre><code>&lt;?php $files=glob(‘*.txt’); print_r($files); ?&gt; /*Output looks like: Array ( [0] =&gt; apples.txt [1] =&gt; bread.txt [2] =&gt; elephants.txt [3] =&gt; sailboats.txt ) */</code></pre> <p>Files can also be returned with a path if directions are specified in the query:</p> <pre><code>&lt;?php $files = glob(‘../images/a*.jpg’); print_r($files); ?&gt; /*Output looks like: Array ( [0] =&gt; ../images/alligator.jpg’ [1] =&gt; ../images/amazon.jpg’ [2] =&gt; ../images/anaconda.jpg’ ) */</code></pre> <p>The full path to each file can be requested by using the realpath() function on the returned values:</p> <pre><code>&lt;?php $files = glob(‘../images/a*.jpg’); /*using this applies the function to each array map*/ $files = array_map(&#39;realpath&#39;,$files); print_r($files); ?&gt; /*Output looks like: Array ( [0] =&gt; C:\wamp\www\images/alligator.jpg’ [1] =&gt; C:\wamp\www\images/amazon.jpg’ [2] =&gt; C:\wamp\www\images/anaconda.jpg’ ) */</code></pre> <p>Please note: This function does not work on remote files.

To uncompress the string we then use gzuncompress().</p> <p>Example:<br /> <pre><code>$string = &quot;Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque congue semper facilisis. Aliquam convallis risus eu ante posuere placerat. Aliquam in nisl nec justo ultrices ornare nec ac mi. Cras ac leo sapien, id luctus elit.

Cras ac lacus eu metus ultrices iaculis. Integer dignissim tristique enim, sed cursus leo pellentesque id. Nullam convallis commodo rhoncus. Maecenas quis sem metus, et tempus odio. Nam et lacus libero, non feugiat elit. Aenean at eros sem. Proin lectus tortor, euismod at sagittis eget, ullamcorper sit amet urna. Phasellus ullamcorper auctor suscipit. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae; Nullam tempus bibendum velit quis suscipit. &quot;; $compressed = gzcompress($string);</code></pre> <p>We can then compare the size of the two strings:</p> <pre><code>echo &quot;Original length: &quot;. strlen($string).&quot;&quot;;</code></pre> <p>Prints, "Original length: 910"</p> <pre><code>echo &quot;Compressed length: &quot;. strlen($compressed).&quot;&quot;;</code></pre> <p>Prints, "Compressed length: 476". So we almost reduced the length of the string by 50%.</p> <p>To uncompress the string we then use the gzuncompress() function:<br /> <pre><code>$uncompressed = gzuncompress($compressed);</code></pre> <p>And in case you were wondering, if you try to echo out the compressed file, the output is just a bunch of gobbledygook random symbols mixed with some actual real characters.</p> <p>Maybe I should also compress my last name so it doesn't flow onto the post area. </p>
