  1. i am creating a responsive website. I'll give you an example. I am retriving 100 items from mysql database using php. I am only showing 20 items per page using simple pagination with arrows. I keep this format on desktop and tablets. However, I would like to show less items when I am viewing the page on a smartphone. So instead of 20 items per page, it'll show 5 items per page along with the pagination arrows. I was wondering if this is possible with PHP or would I have to use javascript?
  2. Hi All, I'm looking to update a mysql column weekly, where by 5 randomly selected rows are given a new random number, from between 1 and the num_rows / 5. This cycle is looped again until all the entries have a new random group for the week. It is to help mix up the players for teams for 5 aside. It needs to be able to accomodate the posibillity of the num_rows not dividing exactly by 5, using ceil perhaps? As an example Name Group a 1 b 2 c 1 d 1 e 1 f 3 g 2 h 1 i 2 j 2 k 2 Then Next week Name Group a 2 b 1 c 2 d 2 e 1 f 2 g 3 h 1 i 2 j 1 k 1 I hope that makes sense. It'll be automated via cron job. I've been really struggling with it, this is as far as I have got. $totalgroupsraw = $num_rows /5; $totalgroups = ceil ($totalgroupsraw); $i = 1; while ($i<$totalgroups) { $pie = mysql_query("UPDATE table SET columnname=5 order by rand() LIMIT 5"); $i++; }; But as you will no doubt be able to see, this doesn't work well at all. I think I am close, but I just can't seem to sort out a good way to do it. Any help much appreciated. Thanks, Matt
  3. Hey guys, I'm trying to limit my query to 5 results, but TOP is not working and LIMIT obviously does not work (I usually work with MySQL). Here is my query: $query = "SELECT PERSON.PERSON_ID, PERSON.LAST_NAME, PERSON.FIRST_NAME FROM PERSON where PERSON.LAST_NAME like '%$q%' or PERSON.FIRST_NAME like '%$q%' order by PERSON.LAST_NAME"; Can someone please point me in the right direction for limiting the query to 5 results? Thank you! ~ Sarah
  4. I have my website paginating files that are shown onscreen. How can I make it so the page only loads the first page's files and then when going on to the next page, it loads the files on that page? Basically what I am trying to do is reduce load time by not loading the files on the pages after page one until the user actually goes to a page after page one. index.php <?php $current_page = isset($_GET['page']) ? intval($_GET['page']) : 1; $items_per_page = 10; $offset = ($current_page - 1) * $items_per_page; $items = glob("entries/*.php"); $total_items = count($items); $total_pages = ceil($total_items / $items_per_page); foreach (array_slice($items, $offset, $items_per_page) as $entry) { include $entry; } echo "<table summary=\"\" cellpadding=\"10\" cellspacing=\"0\" border=\"0\" class=\"global-links-menu\"><tr>"; if($current_page != 1) { $back_page = $current_page - 1; echo "<td ><p><a href='?page=$back_page'>Back</a></p></td>"; } else { $back_page = $current_page - 1; echo "<td ><p></p></td>"; } for($j=1;$j<=$total_pages;$j++) { if($j==$current_page) { echo "<td ><p>$current_page</p></td>"; } else { echo "<td ><p><a href='?page=$j' title='Page $j'>$j</a></p></td>"; } } if($current_page <= $total_pages - 1){ $next_page=$current_page+1; echo "<td ><p><a href='?page=$next_page'>Next Page</a></p></td>"; } else { echo "<td ><p></p></td>"; } /* foreach (glob("entries/*.php") as $filename) { include $filename; } */ ?> </table>
  5. My website is on a free host that not only limit the storage space, like many do, but also limit the processing. It happened to me a few times in the past that my website was temporarily replaced by a parking space for a day or less. Luckily it's just a homepage and most (all?) things on it are not urgently needed. The CMS my site use has a throttling function but I have some directories not covered by the CMS. In one of those there's a ¨H¨which process just fine. The issue is if it was accessed too often, the processing it take might very well shutdown my homepage. Something on my favor: the script only need to be interpreted once in a little while ; once a day should do. A;so if the PHP is not accessed, there's no need to run it anyway ; it's not like some external process (ie: feed aggregator) would fetch content it generated è if the page is not directly accessed, there's no need to interpret it, be it months. Is there a way to limit the processing used by a PHP? Perhaps limiting the number of daily uses. Thank you kindly for your help
  6. another beginners question from yours truly but i was just wondering how i would code a character limit on one of my fields iv been around the internet but i cant find what i need cause i usually come up with the same error code each time. if anyone knows what to do that would be great, hears the code iv been using. <?php $con = mysqli_connect("localhost","root","","nib"); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } // define variables and set to empty values $companyname = $firstname = $address1 = $address2 = $area = $city = $postcode = $email = $website = $clubphone = $homephone = $mobilephone = $typeofbusiness = $renewaldate = ""; if ($_SERVER["REQUEST_METHOD"] == "POST") { $errors = array(); if (empty($_POST["companyname"])) { $errors['companyname'] = "Please Enter Your companyname"; } <input type='text' name='keywords' size='60' value='companyname' maxlength='10' /> elseif(strpos($_POST['companyname'], '/') !== false) { $errors['companyname'] = 'Cannot use /'; } elseif(strpos($_POST['companyname'], 'The') !== false) { $errors['companyname'] = 'Company Names cant start with The'; } elseif(strpos($_POST['companyname'], 'the') !== false) { $errors['companyname'] = 'Company Names cant start with the'; } elseif(strpos($_POST['companyname'], 'THE') !== false) { $errors['companyname'] = 'Company Names cant start with THE'; } else { $companyname = test_input($_POST["companyname"]); } and heres the error code ive been getting. ( ! ) Parse error: syntax error, unexpected '<' in C:\wamp\www\AddLeads\addeadstemplate.php on line 29 aswell as this if i remove this symbol i get one to do with the else if statement witch i kinda need. again if anyone has a solution please get back to me soon as
  7. Can anyone see why my results would return more than 20 rows? $query = "SELECT * FROM mailer "; $limit = "ORDER BY id LIMIT 20 "; $result = mysql_query($query.$limit); if (!$result) { $message = 'Invalid query: ' . mysql_error() . "\n"; $message .= 'Whole query: ' . $query; die($message); } $address = 0; while ($row = mysql_fetch_assoc($result)) { $id=$row["id"]; $email=$row["email"]; $companyID=$row["companyID"]; }
  8. Im creating an online ordering form for a large selection of items, about 1700. Displaying my form works perfect, but when I receive the information and try and get the post variables It stops after 330. If I start my counter at 300, it stop at 630, so there must be a limit of 330 post variables, anyone ever run into this? I'll try and post some code snippets // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } //This query will return about 1700 results $result = mysqli_query($con,"SELECT * FROM formatted"); $a = 0; $currentCategory = ""; $status = "begin"; while($row = mysqli_fetch_array($result)) { echo $_POST['qty' . $a]; if(isset($_POST['qty' . $a]) && ($_POST['qty' . $a] != 0)) { $qty = $_POST['qty' . $a]; $ttl = $qty * substr($row['price'],1); if($currentCategory != $row['subcategory']) { $customerInfo .= '<tr><th colspan = "7" style="background-color: #104E8B; color: #FFF;">' . $row['subcategory'] . '</th></tr>'; $currentCategory = $row['subcategory']; } $customerInfo .= '<tr> <td>' . $row['size'] . '</td> <td>' . $row['description'] . '</td> <td>' . $row['upc'] . '</td> <td>' . $qty . '</td> <td>' . $row['price'] . '</td> <td>' . $ttl . '</td> <td>' . $_POST['notes'] .'</td> </tr>'; $currentCategory = $row['subcategory']; } $a++; } echo '</table>'; mysqli_close($con);
  9. Hi, I can't figure out how to limit the word count fetched from the database. I simply want to show 10 words from the 'body' column. I'm using the below echo code to display the information. echo '<div class="menu"><div class="item">'; echo '<h1><a href="news/display/'.$row['id'].'">'.$row['title'].'</a></h1>'; echo '<img src="../'.$row['image'].'"/>'; echo '<p>'.$row['body'].'</p>'; echo '</div></div>'; Any help is appreciated. Thanks.
