    Looping through session variable array

    <?php
//If form is submitted, call the function and save all data into the array $_SESSION['form'] 
if($_POST['submit'] == "Buy"){ unset($_POST['submit']); setSessionVars(); } 

function setSessionVars() {
   if ( !isset($_SESSION['cart']) ) $_SESSION['cart'] = array();
   $_SESSION['cart'] = array_merge($_SESSION['cart'], $_POST);
   echo <<<HTML
   <table>
      <tr>
         <td><img src="images/{$item['item']}.jpg" /></td>
         <td>{$item['item']}</td>
         <td><input type="text" name="value" value="1" maxlength="30" /><input type="submit" name="puchasednum" value="Update This One Item" /></td>

    Retrieving multipĺe records from MySQL

    $q="SELECT cb_video_categories.category_name,  cb_video_categories.cb_video FROM cb_video_categories, cb_video WHERE REPLACE(cb_video.category, '#', '') = cb_video_categories.category_id";

     

     

     

    Should probably just run:

     

     

    UPDATE cb_video SET category = REPLACE(category, '#', '');

     

     

    in phpmyadmin to replace all #'s and change the type to integer as programming languages handle integers much faster.

    What Thorpe is saying is that having two or more elements with the same ID is against W3C standards, use classes instead.

    Can you style an Option in a drop down ??

    in CSS Help

    If you're selecting the dates from a database just filter them in your query or PHP, it's easy:

     

     

    SELECT date FROM datetable WHERE DATEDIFF(date, NOW()) >= 0

     

     

    Also look into the jquery UI datepicker, you could replace the select box with this with jquery once the page has loaded, IMO it's a lot slicker than a drop-down

     

     

     

       // getdates.php
   // connect to mysql
   $query  = "SELECT date FROM datetable WHERE DATEDIFF(date, NOW()) >= 0";
   $result = mysql_query($query)or die(mysql_error());
   $dates  = array();
   while ( $row = mysql_fetch_row($result) )
      $dates[] = $row[0];
   echo json_encode($dates);


    $(document).ready(function() {
   var selector = 'select'; // select#id, select.class
   $(selector).replaceWith('<input type="text" id="date" >');

   var dates = [];
   $('#date').datepicker({
      dateFormat      : 'dd/mm/yy',
      minDate         : $.datepicker.formatDate('dd/mm/yy', new Date()),
      beforeShowDay   : function (date) {
         if ( typeof dates == 'undefined' )
         {
            $.ajax({
               async   : false,
               url     : 'http://mysite.com/getdates.php',
               dataType: 'json',
               success : function(data) {
                  dates.push(data);
               }
            });
         }
         $.each(dates, function() {
            if ( date === new Date(this) )
               return [true, ''];
         });
         return [false, ''];
      }
   });
});

    Google directions API (auto correction?)

    in Miscellaneous

    Posted

    I'm writing a sort of fake tracking unit in nodeJS, it basically selects a random location, limits it to within some bounds, then I plan to inset the data into a database on around 30 second intervals, it's for a real-time demo of our works tracking system, however, if the latlngs don't happen to land on a road, the directions API returns an empty route, anyone know if there's a way to auto-correct the start / destination of a route?

     

     

    Thanks

    aaah I guess chrome doesn't have it.  I did find it in FireFox...pretty cool

     

     

    +1 for Chrome here, and you can get addons with Chrome, and the developer console (Ctrl+Shift+J) is pretty much the same as firebug from where I'm standing. IE sucks donkey boll0ks but google have developed a plug-in called chrome frame, it's a 1 click install, activated via a meta tag and identified via the user agent string

     

     

    <meta http-equiv="X-UA-Compatible" content="chrome=1" >

     

     

    Simple as that, rounded corners, proper opacity and V8 engine in IE.

    HTML versus PHP

    in PHP Coding Help

    Posted

    As we're into the 'Green' era of recycling, I've used this code on practically every site I've worked on to display my HTML

     

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
  <TITLE><?php echo $title; ?></TITLE>
  <META NAME="Generator" CONTENT="*******">
  <META NAME="Author" CONTENT="**********">
  <META NAME="Keywords" CONTENT="">

  <?php echo $banner; ?>  <>
  <  <div id="content">
  
   <?php echo $output; ?>
   
   
   <>
   <>
</BODY>
</HTML>

     

    As you can see, I can simply do my processing and then include this file with all / some of the variables set.

     

    I've got another couple I include if I need a 2 column or 3 column display

     

     

    Seriously? 4.0 transitional and block-caps tags and attributes?

     

    /?EDIT

     

    To expand, if you're looking to promote re-usable future-proof code, look into HTML 4.01 strict (/best practices)

     

    Some of this includes a space before the closing > of an un-closed tag:

     

    <!-- META //-->
<meta name="description" content="Secure login" >
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" >
<!-- LINKS AND SCRIPTS //-->
<link rel="stylesheet" href="css/login.css" type="text/css" >

    this way, if you ever need to switch to XHTML, search and replace " >", " />"

     

    Also, HTML 4.01 strict is the closest version to HTML 5, so is likely to most resemble it, using this with best practices should make the switch to HTML 5 a little easier.

    Want to learn OOP? Looking for some PHP Buddies

    in Miscellaneous

    Posted

    The problem is that on the most part, people think, "What can I learn from you?" as opposed to "What can we learn from each other?" and when you post a topic like this; it tells people that you want to learn and gives them the impression that you don't know your way around PHP much. Everyone's had that annoying noob that flashes the orange tab at you on windows live every 10 seconds with another 30 lines of code followed by "can you fix this for me?!!!".

     

     

    I've been looking into PHP groups recently, I think me any my boss are going to go to the PHP North West (PHPNW) meetup on April 3rd, I've been told that they have a speaker on who has contributed to the PHP source, should be good.

     

     

    Maybe something like that would be good for you? Just search 

    "PHP group " {name of your town/city}

    in google and then look on freenode for their IRC channel.

     

     

    Also there's already a large community out there to learn from, look at source code of open source projects on git hub or source forge, maybe even contribute to a project (remember, you're never under-qualified to work for free).

    Free directions API/service

    in Miscellaneous

    Posted

    Hi, I am writing some fleet tracking software at work and I want to add a feature that uses the google maps directions API but we are behind a login, we are purchasing a google maps licence but the directions API up's the cost by 100%, and we don't have enough customers to warrant that ATM. I was just wondering if anyone knew of a free directions API, or if I could get around the google licence, like make a PHP page that takes postcodes, makes a google API request and the outputs JSON, putting that in front of the login and then interfacing with that? Anyone know if this would be legit?
