PHP - Bigger Query Instead Of Using Arrays, And Pagination Help
Hi,
I am trying to create a view where the user can sort by any column. What I have made so far works great, but when it comes to pagination, which I will be trying soon, I foresee a problem . The thing is, my code gets data out of a database and puts it into a multidimensional array, which is sorted using afew array sorting functions. It is a query that drives the main loop, and inside that loop are other queries that get various data from other tables, which is where the problem lies when coming to sort with pagination. What I would like to know is how would I build a myslq query that can accomplish the same thing as my code, but do away with the need for the arrays? My code is here, sorry about it being so long: <?PHP if($_POST['targetid']) { $box = array() ; if($_POST['type']) { $extra = 'AND entity_details.typeRef = ?' ; $targetType = $_POST['type'] ; } $sortMode = $_POST['sortmode'] ; $targetUser = $_POST['targetid'] ; include('pdoconnect.php') ; $result = $dbh->prepare("SELECT entity_details.name, entity_contacts.name AS cName, entity_contacts.id, entity_details.countryRef FROM entity_details, entity_contacts WHERE entity_contacts.isPrimary = 1 AND entity_contacts.entityRef = entity_details.id $extra AND entity_details.ownerRef = ?") ; if($extra) { $result->bindParam(1, $targetType, PDO::PARAM_INT) ; $result->bindParam(2, $targetUser, PDO::PARAM_INT) ; } else $result->bindParam(1, $targetUser, PDO::PARAM_INT) ; $result->execute() ; $count = $result->rowCount() ; if($count > 0) { echo "Showing " ; if($targetType == 2) echo "prospects!" ; elseif($targetType == 3) echo "customers!" ; elseif($targetType == 4) echo "leads!" ; else echo "everything." ; echo '<br />' ; } if($count > 0) { $mode = $_GET['sort'] ; echo "<div class='row'>\n" ; echo "<div class='cell'>" ; if($sortMode != 'name') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'name');\">Name</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrname');\">Name</a>" ; echo "</div>" ; echo "<div class='cell'>" ; if($sortMode != 'contact') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'contact');\">Contact</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrcontact');\">Contact</a>" ; echo "</div>" ; echo "<div class='cell'>" ; if($sortMode != 'email') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'email');\">Email</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rremail');\">Email</a>" ; echo "</div>" ; echo "<div class='cell'>" ; if($sortMode != 'tel') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'tel');\">Tel</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrtel');\">Tel</a>" ; echo "</div>" ; echo "<div class='cell'>" ; if($sortMode != 'payment') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'payment');\">Payment Terms</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrpayment');\">Payment Terms</a>" ; echo "</div>" ; echo "<div class='cell' style='width:30px;'>" ; if($sortMode != 'currency') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'currency');\">Cur</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrcurrency');\">Cur</a>" ; echo "</div>" ; echo "<div class='cell'>" ; if($sortMode != 'country') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'country');\">Country</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrcountry');\">Country</a>" ; echo "</div>" ; echo "<div class='cell' style='width:100px;'>" ; if($sortMode != 'lastc') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'lastc');\">Last Contacted</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrlastc');\">Last Contacted</a>" ; echo "</div>" ; echo "<div class='cell' style='width:100px;'>" ; if($sortMode != 'lastm') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'lastm');\">Last Marketed</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrlastm');\">Last Marketed</a>" ; echo "</div>" ; echo "<div class='cell' style='width:100px;'>" ; if($sortMode != 'lastd') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'lastd');\">Last Deal</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrlastd');\">Last Deal</a>" ; echo "</div>" ; echo "<div class='cell' style='width:50px;'>" ; if($sortMode != 'cltv') echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'cltv');\">CLTV</a>" ; else echo "<a onclick=\"traderSelectCustomer('$targetUser', '$targetType', 'Rrcltv');\">CLTV</a>" ; echo "</div>" ; echo "</div>\n" ; } else { echo "You have no " ; if($targetType == 2) echo "prospects!" ; elseif($targetType == 3) echo "customers!" ; elseif($targetType == 4) echo "leads!" ; else echo "nothing!" ; } while($row = $result->fetch(PDO::FETCH_ASSOC)) { $id = $row['id'] ; $countryid = $row['countryRef'] ; // Get primary contact data. $resultName = $dbh->prepare("SELECT entity_contacts_emails.email, entity_contacts_telephones.tel FROM entity_contacts_emails, entity_contacts_telephones WHERE entity_contacts_emails.contactRef = ?

Can anyone tell me how? Similar TutorialsLets say that I have several arrays, as follows: $array1 = ('A', 'B', 'C', 'D', 'E', 'F', 'G'); $array 2 = (3, 4, 5, 6, 7, ; $array 3 = ('!', '@', '#', '$', '%', '^'); These three arrays are stored as session variables, and the page showthem.php displays the arrays. However, the page can only display a maximum of 4 items at a time. Therefore, the pages should display as follows: Page 1 = -> Table 1 (LETTERS) A, B, C, D Page 2 = -> Table 1 (LETTERS) E, F, G -> Table 2 (NUMBERS) 3 Page 3 = -> Table 1 (NUMBERS) 4, 5, 6, 7 Page 4 = -> Table 1 (NUMBERS) 8 -> Table 2 (CHARACTERS) !, @, # Page 5 = -> Table 1 (CHARACTERS) $, %, ^ I can't figure out how to use the count() function and the array indexes to create proper pagination on showthem.php Obviously I would like, at the top to have page numbers that link to the appropriate content from the arrays. As in: <a href="showthem.php?page=1"> 1 </a> <a href="showthem.php?page=2"> 2 </a> <a href="showthem.php?page=3"> 3 </a> <a href="showthem.php?page=4"> 4 </a> <a href="showthem.php?page=5"> 5 </a> This is a major puzzle for me ... thanks in advance.

Many thanks Pete I had originally created a topic on my pagination not working, but I found out what the problem was. The topic I had created was irrelevant to what the problem was... but anyway, here's my situation: I've got a query that searches in a MySQL table for a certain value. Then it list's all the findings in a table (pretty simple). Anyway, I obviously want to have a pagination system to make it easier to manage the amount of data per page. The pagination works fine, it's used for another query that just pulls data (so NO WHERE clause is used!). That is what is causing the problem. I spent hours trying to figure out why this is happening, then I figured out that the only difference between the pagination that works and the one that doesn't is the query have the where clause. What happens when the where clause is used is that the pagination works fine on the first page, but if you click the link to go to a different page, the page is empty and turns up no results so the mysql data that is pulled is lost. So here is my code. I don't know exactly why the where clause causes the pagination to not work. Code: [Select] $conn = mysql_connect("$mysql_host","$mysql_user","$mysql_password") or trigger_error("SQL", E_USER_ERROR); $db = mysql_select_db("$mysql_database",$conn) or trigger_error("SQL", E_USER_ERROR); // find out how many rows are in the table $sql = "SELECT COUNT(*) FROM ACTIVE WHERE MODEL='$model'"; $result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR); $r = mysql_fetch_row($result); $numrows = $r[0]; // number of rows to show per page $rowsperpage = 5; // find out total pages $totalpages = ceil($numrows / $rowsperpage); // get the current page or set a default if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) { // cast var as int $currentpage = (int) $_GET['currentpage']; } else { // default page num $currentpage = 1; } // end if // if current page is greater than total pages... if ($currentpage > $totalpages) { // set current page to last page $currentpage = $totalpages; } // end if // if current page is less than first page... if ($currentpage < 1) { // set current page to first page $currentpage = 1; } // end if // the offset of the list, based on current page $offset = ($currentpage - 1) * $rowsperpage; $sql = "SELECT * FROM ACTIVE WHERE MODEL='$model' ORDER BY INDEX_ID DESC LIMIT $offset, $rowsperpage"; $result = mysql_query($sql, $conn) or die('Error: ' . mysql_error()); echo " <table width=100% align=center border=1 class=\"mod\"><tr> <td align=center bgcolor=#00FFFF><b>Rating</b></td> <td align=center bgcolor=#00FFFF><b>Title</b></td> <td align=center bgcolor=#00FFFF><b>Make/Model</b></td> <td align=center bgcolor=#00FFFF><b>Type</b></td> <td align=center bgcolor=#00FFFF><b>Difficulty</b></td> <td align=center bgcolor=#00FFFF><b>Comments</b></td> <td align=center bgcolor=#00FFFF><b>Views</b></td> </tr>"; while ($row = mysql_fetch_assoc($result)) { { // Begin while $title = $row["TITLE"]; $type = $row["TYPE"]; $difficulty = $row["DIFFICULTY"]; $comments = $row["COMMENT_TOTAL"]; $id = $row['INDEX_ID']; $rating = $row["RATING_AVERAGE"]; $make = $row["MAKE"]; $model = $row["MODEL"]; $views = $row["HITS"]; echo " <tr> <td>$rating/10</td> <td><a href=\"mod.php?id=$id\">$title</a></td> <td>$make - $model</td> <td>$type</td> <td>$difficulty</td> <td>$comments</td> <td>$views</td> </tr>"; } } echo "</table><br />"; /****** build the pagination links ******/ echo "<center>"; // range of num links to show $range = 3; echo "<i>Page: </i>"; // if not on page 1, don't show back links if ($currentpage > 1) { // get previous page num $prevpage = $currentpage - 1; // show < link to go back to 1 page echo " <a stylehref='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'>Previous</a> - "; } // end if // loop to show links to range of pages around current page for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) { // if it's a valid page number... if (($x > 0) && ($x <= $totalpages)) { // if we're on current page... if ($x == $currentpage) { // 'highlight' it but don't make a link echo " <b>$x</b> "; // if not current page... } else { // make it a link echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> "; } // end else } // end if } // end for // if not on last page, show forward and last page links if ($currentpage != $totalpages) { // get next page $nextpage = $currentpage + 1; // echo forward link for next page echo " - <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>Next</a> "; } // end if /****** end build pagination links ******/ mysql_close($conn); } echo "$pagination</center>"; ?> I really appreciate the help! Thanks. I want a simple function that converts a sql query into two queries for pagination purposes. So if the sql query is "SELECT `Name` FROM table1" I would like to perform: "SELECT COUNT(*) FROM table 1" and "SELECT `Name` FROM table1 LIMIT 10, 20" (example) (1) Would this work for most basic queries? (obviously if LIMIT wasn't already used)? (2) What command would I use to convert "SELECT `Name` FROM table1" to "SELECT COUNT(*) FROM table 1" I am aware there is more involved than this, but am just interested in the query side of things. Hi there I adapted the pagination tutorial from here on PHP Freaks so that it can deal with a db query. The pagination itself works just fine but I have a small issue, hopefully someone can help me please. I have set up the query so that it won't allow blank searches. The script works perfectly well without the pagination. With the pagination, the script now returns a few results as well as the 'you didn't enter a search-term' message - can someone help me tidy it up please? I'm guessing that I've put the search=$search term in too many places in the pagination script. This is the query Code: [Select] if (isset($_GET['search'])) { $searchTerms = trim($_GET['search']); $searchTerms = strip_tags($searchTerms); // remove any html/javascript. if (strlen($searchTerms) < 1) { $error[] = '<div class="messagebox">You didn\'t specify a search term</div></div>'; $error[] = '<div class="small"><a href="search2.php"><p>Search Again?</p></a></div>'; } else { $searchTermDB = mysql_real_escape_string($searchTerms); // prevent sql injection. } $sql = "SELECT * FROM pro_words WHERE word LIKE '%{$searchTermDB}%' ORDER BY word LIMIT $offset, $rowsperpage"; $result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR); $num_rows = mysql_num_rows($result); //display results if (mysql_num_rows($result) < 1) { $error[] = '<div class="messagebox">Sorry, your search term yielded no results.</div>'; $error[] = '<div class="small"><a href="search.php"><p>Search Again?</p></a></div>'; } else { echo '<div class="messagebox">Here are your search results.</div>'; while ($list = mysql_fetch_array($result)) { // echo data echo '<div class="small"><a href="word.php?w=' . $list['word'] .

I've got a page with pagination set up, but I can't figure out where I went wrong with the links at the bottom. When I do a search, it generates the proper number of links, but clicking on the links goes to a page with a whole row of 20 links at the bottom and no results on the page. (my search should show 3 pages with 2 records on each page) I've looked through the tutorial here and one in a book on pagination. Not seeing what's wrong. I'd narrow this down if I knew where it was causing the problem. pagination links are at the very bottom of the code.

Here's what used to work: Code: [Select] //the current URL $page_name = $_SERVER["REQUEST_URI"]; //remove any old limit from query before requesting a new limit $tmp = array(); foreach ($_GET as $fld => $val) if ($fld != 'limit') $tmp[] = $fld . '=' . $val; $page_name = $_SERVER['SCRIPT_NAME'] . '?' . implode('&',$tmp); //sets the number of records to be displayed on the page <form> <select name="link"> <option value="<? echo "$page_name" ?>&limit=25">25 records per page</option> <option value="<? echo "$page_name" ?>&limit=50">50 records per page</option> <option value="<? echo "$page_name" ?>&limit=100">100 records per page</option> </select> </form> This grabs the current URL, and clears the &limit= string before a new limit is introduced to avoid: www.example.com/test.php?sub=math[]&sub[]=science&limit=25&limit=50&limit=100 The problem, is that my URL is already querying an array: www.example.com/test.php?sub[]=math&sub[]=science So now, when I apply the form above to this URL set the new limit to 50 records per page the URL actually becomes: www.example.com/test.php?sub=Array&limit=50 Warning: Invalid argument supplied for foreach() ... on line 147 I guess I've broken the array? Code: [Select] //line 147 echo "subject:<BR />"; if(!empty($_GET['sub'])) foreach($_GET['sub'] as $sub) { echo "$sub <BR />\n"; } ~Wayne Given the following query,
SELECT t1.a, t1.b, t2.c FROM t1 INNER JOIN t2 ON t2.id=t1.t2_id WHERE t1.pk=123;I get the following three records: array( array('a'=>1,'b'=>2,'c'=>4), array('a'=>1,'b'=>2,'c'=>5), array('a'=>1,'b'=>2,'c'=>8) )What would be the best way to get just one record such as the following? array('a'=>1,'b'=>2, 'c'=>array(4,5,8))My thoughts were to use MySQL's GROUP_CONCAT, and then use implode() to turn it into an array, but didn't know if there was a better way. Thanks I've followed the PHP Freaks pagination tutorial which you can find here. And I also got it to work, the only problem is that the script won't work when I use the query outside of the function. Here's the function: <?php function knuffix_list ($query, $dbc) { // find out how many rows are in the table: $query_row = "SELECT COUNT(*) FROM con"; $query_run = mysqli_query ($dbc, $query_row); $row = mysqli_fetch_row($query_run); $num_rows = $row[0]; // number of rows to show per page $rows_per_page = 5; // find total pages -> ceil for rounding up $total_pages = ceil($num_rows / $rows_per_page); // get the current page or set a default if (isset($_GET['current_page']) && is_numeric($_GET['current_page'])) { // make it an INT if it isn't $current_page = (int) $_GET['current_page']; } else { // default page number $current_page = 1; } // if current page is greater than total pages then set current page to last page if ($current_page > $total_pages) { $current_page = $total_pages; } // if current page is less than first page then set current page to first page if ($current_page < 1) { $current_page = 1; } // the offset of the list, based on current page $offset = (($current_page - 1) * $rows_per_page); echo "test " . $query; // SCRIPT ONLY WORKS IF I INSERT QUERY HERE $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT $offset, $rows_per_page"; $data = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); // Loop through the array of data while ($row = mysqli_fetch_array ($data)) { global $array; // Variables for the table $con_id = $row['con_id']; $likes_count = $row['likes']; $dislikes_count = $row['dislikes']; $dbuser_name = $row['nickname']; $dbuser_avatar = $row['avatar']; $user_id = $row['user_id']; // The TABLE echo "<table padding='0' margin='0' class='knuffixTable'>"; echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='avatar/$dbuser_avatar' alt='avatar' /></td>"; echo "<td class='knuffix_username'><strong><a href='profile.php?user=$dbuser_name' title='Profile of $dbuser_name'>" . $dbuser_name .

I put the test echo above the query to see how the query looks like when I induce the query from the outside through the function parenthesis into the function, and this is what I get printed out: test SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT , Obviously the $offset and the $rows_per_page variables are not set, when I induce the query from the outside into the function. So in that sense my question is: How can I induce the query from the outside into the function SO THAT the $offset and the $rows_per_page variables are set as well and NOT empty? p.s. I need the query outside of the function because I'm using a sort by category functionality. I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually. the results i am trying to generate is that each item in generated array. Array to convert array( "account" => array( "login", "register", "logout", "edit", ), "p" => array( "report", ), "array1.0" => array( "array2.0" => array( "array3.0", "array3.1 ), "array2.1", ), generating the array will look like this
Array ( [0] => account [1] => account/login [2] => account/register [3] => account/logout [4] => account/edit [5] => p [6] => p/report [7] => array1.0 [8] => array1.0/array2.0 [9] => array1.0/array2.0/array3.0 [10] => array1.0/array2.0/array3.1 [11] => array1.0/array2.1 ) The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array.
I have this thing that i am trying to make but i cant get it to work.. can anyone help?

I just installed this new script here http://webhost.pro/domain-check.php it's a basic domain availability tool. I am trying to make a form that can be used on any page forward to this page with the content. The page loads with this in the url webhost.pro/domain-check.php?domain=dwhs.net and will run the page. So I can make a form that just submits to that page and sends the details. I made this page for testing http://webhost.pro/test.html But no go, here is the code: <form id="search" action="/domain-check.php" method="GET"> <input type="text" name="s"> <a onClick="document.getElementById('search').submit()" class="button1">Search</a> <div class="clear"></div> </form> Thanks! I have two arrays, both with the same key values. I'd like to combine them. So for instance...

Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!
