  1. I am having trouble with an array. Don't know to much about them. I have a form on create.php where they can choose multiple items for there trade. On the create.pro.php is where I want it to put all the checked items from create.php together separated by commas into my database. (That way I can explode them later to get them separately - correct?) create.php $stmt = $mysqli->prepare("SELECT id, owner, item_id, uses_left FROM useritems WHERE owner = ? ORDER BY item_id"); $stmt->bind_param('s', $userid); $stmt->execute(); $stmt->store_result(); $countitems = $stmt->num_rows; $stmt->bind_result($id, $owner, $item_id, $uses_left); ECHO <<<END <center> <p><a href="index.php">Home</a> | <a href="index.php?type=me">My Trades</a> | <a href="create.php">Create Trade</a> | <a href="offers.php\">My Offers</a> | <a href="search.php">Search</a></p> <b>Note:</b> Spirits can not be traded therefore will not be shown in the items below. <form action="create.pro.php" method="post"> <center><table cellspacing="0" cellpadding="0" width="800"> END; while ($stmt->fetch()){ $stmt2 = $mysqli->prepare("SELECT name, type, value, rarity, image, description, retired FROM items WHERE itemid = ? AND type != 'spirit' AND magic_num = ?"); $stmt2->bind_param('si', $item_id, $uses_left); $stmt2->execute(); $stmt2->store_result(); $stmt2->bind_result($name, $type, $value, $rarity, $image, $description, $retired); $stmt2->fetch(); $stmt2->close(); $y = $x % 5; if ($y == 0) { echo "<tr>"; } if (!empty($name)){ echo " <td> <img src=\"$baseurl/images/items/$image\"><br> <input type=\"checkbox\" name=\"use_item\" value=\"$itemid\"> <b>$name</b><br> </td> "; } if ($y == 4) { echo "</tr>"; } $x++; } $stmt->close(); echo "</table> <p align=\"center\">Include sP: <input type=\"text\" name=\"include_amount\" size=\"20\"></p> <p align=\"center\">Wishlist: <input type=\"text\" name=\"wishlist\" size=\"40\"></p> <input type=\"submit\" name=\"submit\" class=\"mybutton\" value=\"Create Trade\"></center> </form> </center>"; create.pro.php (where the form leads to - this is the page I need help with) $array = array($_POST['use_item']); $items = implode(", ", $array); $include_amount = $_POST['include_amount']; $wishlist = $_POST['wishlist']; $stmt = $mysqli->prepare("INSERT INTO trades (items, sPoints, wishlist, owner) VALUES (?, ?, ?, ?)"); $stmt->bind_param('siss', $items, $include_amount, $wishlist, $userid); $stmt->execute(); $stmt->store_result(); $stmt->fetch(); $stmt->close(); die(header("Location: index.php?note=Trade+created.")); Thanks for any help!
  2. Folks, Q1. A function parameter that takes in a constant, can it always take in a variable, unless it needs a handle ? While going through the Explode function tutorial, I did not come across anything that states the 3rd parameter (explode limit) in the Explode function has to be a string or a constant. Like so: <?php //Tutorial: http://www.tizag.com/phpT/php-string-explode.php echo "Script 1"; //Using a Constant as 3rd parameter in the Explode function. Using FOR function. $phrase = "Please don't blow me to pieces."; $words = explode(" ", $phrase); print_r($words); for($i = 0; $i < count($words); $i++){ echo "Piece $i = $words[$i] <br />"; } $explode_limit = 4; $words = explode(" ", $phrase, 4); for($i = 0; $i < count($words); $i++){ echo "Limited Piece $i = $words[$i] <br />"; } print_r ($words); ?>
  3. Php Gurus, Is there a way how you could have more than one delimiter in the following functions ? explode implode Tutorials always shows one. But let us say, we need more than one. In that case, what would you do without coding separately one by one for each delimiter ? If regex then I'd like to see some code samples. Remember, a code sample would be appreciated by all present & future newbies. Explode Imagine I want to explode this: 'The "quick brown" fox jumps over the \'lazy dog\'.' To this: ' The "quick brown" fox jumps over the \'lazy dog\' . ' As you can see, we need 3 delimiters: Space " ' Now, imagine I need to implode this: " The 'quick brown' fox jumps over the \"lazy dog\" . " To this: "The 'quick brown' fox jumps over the \"lazy dog\"." As you can see the combiners are the same in this case like they were in the other case's delimiters. I don't want to be coding 3 separate snippets to use each delimiter/combiner. Hence the question. Imagine, I got millions of html files and I need to deal with millions of lines of content like the examples shown above (which was just one line each). Ok, I was about to post this now and a thought just crossed my mind. Maybe the delimiters/combiners can be placed in an array and then on each loop the delimiter/combiner can change ? But how do I call the delimiters/combiners from each array key ? Dump the array values to a variable ? Any sample would be appreciated. Saying all this, I will try myself to build 2 snippets from one of the codes from one of my previous threads but don't hold your breath and I prefer your feed-back if it's possible to do things with array like I'm pondering. @requinix, Yes, I am creating my own terminology again: Combiner/Joiner.
