PHP - Creating Automatic Pages When Pulling Rows From Mysql
Hi all,
I have a database which contains customer details. We have a php script which pulls the records from the database and puts them into a table on the page. Currently, it fetches all the customer records. This wasn't such a problem when there was only a few customers in the db but this is a bit higher now! Is there any way I can modify the script to only show 20 per page and add links to page 2 etc along the bottom, which can be clicked to show the next 20 and so on? I can post my current code if need be, Thanks. Similar TutorialsHey, I was wondering if there is a way to pull multiple rows at once using a list of unique identifiers. For example, I want to pull the rows with the IDs of 4,13,91 and 252 I know the WHERE part of this query is incorrect, but I'm putting it to hopefully help you guys understand what I'm looking for. $result = mysql_query("SELECT * FROM $table WHERE id='4' OR '13' OR '91' OR '252'"); while($row = mysql_fetch_array($result)) { echo($row['name']); } Or is the best way simply to do it one query at a time without a while statement? There could be as many as a few dozen records being pulled per page. Code: [Select] id: 20 Reason: this is a test id: 21 Reason: Tests id: 22 Reason: Lolcatz id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: Reason: id: 36 Reason: Test As you can see on the 2nd code box there are id's 20,21,22 and 36 in the database the rest are not active in the database. i am using using Code: [Select] for to pull out the id that starts with the lowest value in the database, and only have it run until it gets to the maximum value. Code: [Select] for ($id=$set_min; $set_max<=7; $id++) { // $id=$set_min is pulling the smallest value and $set_max is pulling the maximum value so it stops after it gets to 36 $query=mysql_query("SELECT * FROM posted WHERE id = $id"); $query_row=mysql_fetch_array($query); $reason = $query_row[reason]; $pulled_id = $query_row[id]; $pulled_pic22 = $query_row[picture]; $href_pull = "<a href=" . "search.php?id=" . "$id" .">"; echo "<td>" . $href_pull . "<img src=$pulled_pic22 height=200 width=150 />" . "</td>"; } how would i make it so i do not pull the values 23-35 which are not in the active database. Example: http://dev.hackmuch.com/of-the-day/search.php?id=36 So basically I have a database full of players 'items'. Each player has 2 items. and I need to make a circle with these players with only specific items involved. Each circle can only contain 6 players. The items needed to create this circle a pigs spice sugar cows aluminium marble iron lumber wheat water random random so 10 resources are literally needed to create this circle but 12 is needed to make it a 'circle' if you get me. I'd like to note that it is possible that any of these players can have a combination of any of resources listed above. I've created a form that allows people to submit players resources into my mysql database. I heard it was possible that I could code some type of filter/sort code to sort out the players resources from my database automatically into a set that will match what is needed (without any repeat of resources) and having a php code to export it into html format for viewing pleasures. I really have no idea how to go about this in mysql or php. But if somebody could help me out i'd be ever so glad. Also to note: this isn't school work or something. It's from a game I play and i'm just trying to make my job in it easier. I was thinking of maybe a php code that will run through all the possible partners in order to create this set like run through 100s of different sets until the required set is obtained. I heard this is just about possible. Can anyone help me? Looking forward to all the great help around here. Thanks Samuz PS: Each item/resource can only appear once in each circle. Hey guys was wondering if anyone could modify the code below to have $output = 'yes' if the number of rows equal 10, 20, 30, 40, 50, 60, 70, 80......... etc $dbhost = '******'; $dbuser = ''******';'; $dbpass = ''******';'; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('MYSQL N/A - Please Contact Admin'); $dbname = ''******';'; mysql_select_db($dbname); $query="SELECT * FROM documentaryinfo"; $result=mysql_query($query); $num=mysql_numrows($result); mysql_close($conn); ?> Thanks -------------------------------------------------------------------------------------------------------- Watch Free Documentaries Online - The Documentary Database www.free-documentaries-online.com -------------------------------------------------------------------------------------------------------- Hey! I have it so users can submit info to my site. They have to check some check boxes and radio buttons. I want them to be able to edit this information, so I want to have the data pulled from the MySQL database and have the correct radio button selected (and the text bolded). So I'm thinking some sort of array to check for each value in the database... but I don't really know. There are a few groups of radio boxes and check boxes but here is an example of one. Code: [Select] <input type="radio" name="stage" value="Stage 1" /> Stage 1 <input type="radio" name="stage" value="Stage 2" /> Stage 2 <input type="radio" name="stage" value="Stage 3" /> Stage 3 The information is pulled from the database like this: Code: [Select] $res=mysql_query("SELECT * FROM ACTIVE WHERE INDEX_ID=$id"); if(mysql_num_rows($res)==0) echo "There is no data in the table <br /> <br />"; else { for($i=0;$i<mysql_num_rows($res);$i++) { $row=mysql_fetch_assoc($res); } } So when I pull information (lets say I want to echo it) it'd look like this: Code: [Select] $row[STAGE] The value for the stage selection can only be Stage 1, Stage 2 or Stage 3 so I need it to be selected when the page loads. Thanks! Hi, I have a table that contains posts and each post has a datetime field. Im trying to work out how I can show entries from today, this week and this month so I can have a link that shows all posts from today or this month etc. Any one know how I can do this ? My current piece of code that pulls the data from the db looks like this : Code: [Select] $texts= mysql_query("SELECT * FROM submittedtexts Order by id DESC LIMIT " . (($page - 1) * 6) . ", 6"); I want to add a bit that acts like : WHERE date = today Hope that makes sense, Im a bit of a newbie Thanks in advance, Scott Hi all: I have been going nuts trying to get this to work. I have gone through many attempts based on internet searches and examples that simply do not work. I have files stored in my MySQL db. The files cna be of any type and are being displayed in a listed report. The files are hyperlinked and clickable, but here is the issue: When I click on a file in: http://development.products-and-services.ca/cms/test.php I get: http://development.products-and-services.ca/cms/test2.php?content=DHall_CV_webdev_eng.pdf as a blank page result. The objective is to get a file download alert or to see the file in the browser. Any ideas? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=344772.0 ok, I'm not sure I know how to ask this question, but I've created a table that allows the user to add rows. The problem is, upon submit only the last row creates variables. How can I make sure every cell in every row sets a different variable? This is going to be a purchase order system. Here is my code: Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Insert Table Row using DOM</title> <script language="javascript"> function addRow() { var tbody = document.getElementById("po_table").getElementsByTagName("tbody")[0]; var row = document.createElement("TR"); var cell1 = document.createElement("TD"); var cell2 = document.createElement("TD"); var cell3 = document.createElement("TD"); var inp1 = document.createElement("INPUT"); inp1.setAttribute("type","text"); inp1.setAttribute("name","quantity"); cell1.appendChild(inp1); var inp2 = document.createElement("INPUT"); inp2.setAttribute("type","text"); inp2.setAttribute("name","description"); cell2.appendChild(inp2); var inp3 = document.createElement("INPUT"); inp3.setAttribute("type","text"); inp3.setAttribute("name","unit_cost"); cell3.appendChild(inp3); row.appendChild(cell1); row.appendChild(cell2); row.appendChild(cell3); tbody.appendChild(row); //alert(row.innerHTML); } </script> </head> <body> <form method="post" action="review_po.php"> <table id="po_table" border="1"> <tbody> <tr> <th bgcolor="#c1c1c1">Quantity</th> <th bgcolor="#c1c1c1">Description</th> <th bgcolor="#c1c1c1">Unit Cost</th> </tr> <tr> <td><input type=text name="quantity"></td> <td><input type=text name="description"></td> <td><input type=text name="unit_cost"></td> </tr> </tbody> <tfoot> <tr> <th bgcolor="#e0e0e0">1</th> <th bgcolor="#e0e0e0">Shipping</th> <td><input type=text name="shipping"></td> </tr> <tr> <th bgcolor="#e0e0e0">1</th> <th bgcolor="#e0e0e0">Tax</th> <td><input type=text name="tax"></td> </tr> </tfoot> </table> <input type="button" value="Insert Row" onClick="addRow();"> <input type="submit" value="Review" name="review_po"> </form> </body> </html> right now it goes to this page: Code: [Select] <?php //convert to variables $quantity = $_POST['quantity']; $description = $_POST['description']; $unit_cost = $_POST['unit_cost']; $extended_cost = $_POST['extended_cost']; $shipping = $_POST['shipping']; $tax = $_POST['tax']; ?> <?php echo $quantity; ?><br> <?php echo $description; ?><br> <?php echo $unit_cost; ?><br> <?php echo $extended_cost; ?><br> <?php echo $shipping; ?><br> <?php echo $tax; ?><br> here is the page: http://po.shopphgmag.com/create_po.html Thanks for looking Hi Everyone, Please excuse my lack of tech. terminology. I'm in the learning stages of php/myslq Do you know how both the below pages are very similiar. The only thing that's different is the actual location(s). My question is, is the same code being used for all of these template pages? If so, how does the code know differentiate between different states/cities/? Does each state or even city have a different template? <<--- Thinking out loud here, I don't believe so because that would defeat the purpose of php/mysql. What do you think? http://cars.oodle.com/regions/illinois/ http://cars.oodle.com/regions/indiana/ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> http://cars.oodle.com/regions/illinois/ <<--- Assuming this code is being used on the "state template" how does the php/mysql code on this page know how to show data from the Bloomington area of Illinois? (assuming it's not custom code for the above page) http://cars.oodle.com/used-cars/bloomington-il-area/ <<--- Assuming this code is being used on the "cars template" how does the php/mysql code on this page know how to show data from the Bloomington area of Illinois? (assuming it's not custom code for the above page) Thanks everyone! I have not created any code for this as I dont know where to start, or what its even called. I am on about trying to create a page dynamically depending on the id which is selected. Parts of the URL will change depending on what id is selected for example: 'http://www.facebook.com/home.php?sk=h. i am wanting to create a video website, where when the thumbnail of a video is clicked, a new page is loaded with that more details of the video and the video itself, and im guessing the url would change to identify the id of the video. I cannot create a page for every video by hand, as i will have many videos and this is not very efficient. I am just after the name of this technique or a pointer to a tutorial for how to achieve this. Thanks, Matlab I have designed and created a ecommerce website that allows the user to add products to a shopping cart and for the admin to edit the inventory list. However i would like to have a navigational bar on the website where the user can choose a brand of product and the webpage shows only that brand. I know i can do this by using the WHERE command in a query however would i have to make a separate web page for each brand? Thanks Boldonglen im wondering how to get php to read the latest row (instead of show them all) and when another one comes it replaces it once the page refreshes I'm trying to pull user referral data from my database. This is what I have so far. <table cellpadding="0" cellspacing="0" style="border:1px #000000 solid;" width="68%"> <tr> <td bgcolor="#eeeeee" style="padding:2px;border-right:1px #000 solid;border-bottom:1px #000 solid;"><font size="2" face="verdana"><b> User </b></font></td> <td bgcolor="#eeeeee" style="padding:2px;border-right:1px #000 solid;border-bottom:1px #000 solid;"><font size="2" face="verdana"><b> </b></font></td> <td bgcolor="#eeeeee" style="padding:2px;border-right:1px #000 solid;border-bottom:1px #000 solid;"><font size="2" face="verdana"><b> Date </b></font></td> <td bgcolor="#eeeeee" style="padding:2px;border-bottom:1px #000 solid;"><font size="2" face="verdana"><b> Visits </b></font></td> </tr> <? $lole=$_COOKIE["usNick"]; $tabla = mysql_query("SELECT * FROM tb_users where username='$lole' ORDER BY id ASC"); while ($row = mysql_fetch_array($tabla)) { echo "<tr><td><font size=\"2\" face=\"verdana\">"; echo $row["username"]; echo "</font></td><td><font size=\"2\" face=\"verdana\">"; echo $row["email"]; echo "</font></td><td><font size=\"2\" face=\"verdana\">"; echo $row["joindate"]; echo "</font></td><td><font size=\"2\" face=\"verdana\">"; echo $row["visits"]; echo "</font></td></tr>"; } echo "</table>"; ?> <script type="text/javascript"> initSortTable('myTable',Array('S','N','S','N','S')); </script> I just found out my user ID is missing from database.. Ok I am trying to delete some rows from a database. I have done this before with success so I thought I could use the same method just modify it a little and it would work. Man was I wrong. Any help on this is much appreciated below is my code. Code for the Query to get the data from the database and for displaying the results in a table: Code: [Select] //GET DATA $sql = "SELECT * FROM `".$tblname."` ORDER BY $orderby $sort LIMIT $startrow,$limit"; $result = mysql_query($sql) or die(mysql_error()); $result2 = mysql_query($sql); //START TABLE AND TABLE HEADER echo "<form name='form1' method='post' action=''><table style='font-size:9.5px;'>\n<tr><th>Delete</th>"; $array = mysql_fetch_assoc($result); foreach ($array as $key=>$value) { if($config['nicefields']){ $field = str_replace("_"," ",$key); $field = ucwords($field); } $field = columnSortArrows($key,$field,$orderby,$sort); echo "<th>" . $field . "</th>\n"; } echo "</tr>\n"; //reset result pointer mysql_data_seek($result,0); //start first row style $tr_class = "class='odd'"; //LOOP TABLE ROWS while($row = mysql_fetch_assoc($result)){ echo "<tr ".$tr_class.">\n<td><a href='remove_rec.php?id=". $rows['ID'] . "'><p>Delete</p></a>"; echo "</td>"; foreach ($row as $field=>$value) { echo "<td>" . $value . "</td>\n"; } echo "</tr>\n"; //switch row style if($tr_class == "class='odd'"){ $tr_class = "class='even'"; }else{ $tr_class = "class='odd'"; } } //END TABLE echo "</table>\n</form>"; Here is the code that should delete the row: Code: [Select] $tblname = 'tablename'; // get value of id that sent from address bar $id=$_GET['ID']; // Delete data in mysql from row that has this id $sql="DELETE FROM $tblname WHERE ID='$id'"; $result=mysql_query($sql); // if successfully deleted if($result){ echo "Deleted Successfully"; echo "<BR>"; echo "<a href='leads3.php'>Back to Results</a>"; } else { echo "ERROR"; } When I click on the link to delete a record it redirects me to the appropriate page with the "Deleted Successfully" message but when I go to view the results the row was not deleted. Any help on this would, again, be greatly appreciated. How would I make a script that would delete any row in a MySQL table that was more than 7 days old? I have a MySQL query that returns rows containing date_add column like below:
DATE(date_add) 2014-01-07 2014-01-07 2014-01-07 2014-01-07 2014-01-08 2014-01-15 2014-01-20 2014-01-20 2014-01-20 2014-01-26 2014-01-28 2014-02-16 2014-02-16 2014-02-16 2014-02-16 2014-02-16 2014-02-16 2014-02-16 2014-02-18 2014-02-18 2014-03-08 2014-03-08How can I have pagination based on dates and show rows with the same date in a page and not just based on predefined limit number? Here's the error: Code: [Select] Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/stayway1/public_html/www.one-mafia.com/eng/inboxread.php on line 99 Here's lines 90-110: (99 in bold) Code: [Select] if (strip_tags($_POST['Accept_OC'])){ $oc_id=strip_tags($_POST['oc_id']); if (strip_tags($_POST['place']) == "we"){ $use="we_inv"; $a="we"; $query= "SELECT * FROM oc WHERE we_inv='$username' AND id='$oc_id'"; }elseif (strip_tags($_POST['place']) == "ee"){ $use="ee_inv"; $a="ee"; $query= "SELECT * FROM oc WHERE ee_inv='$username' AND id='$oc_id'"; }elseif (strip_tags($_POST['place']) == "driver"){ $use="driver_inv"; $a="driver"; $query= "SELECT * FROM oc WHERE driver_inv='$username' AND id='$oc_id'"; } $round=mysql_query($query); [b]$check=mysql_num_rows($round);[/b] if ($check != "0"){ echo "You are now in that OC"; mysql_query("UPDATE `oc` SET `$a`='$username' WHERE `id`='$oc_id'"); mysql_query("UPDATE `users` SET `oc`='1' WHERE `username`='$username'"); } } if (strip_tags($_POST['Yes_street'])){ $race_id=strip_tags($_POST['race_id']); if ($fetch->street != "0"){ echo "Your in a race."; }elseif ($fetch->street == "0"){ if ($fetch->last_race >= time()){ echo "You cant do anouther race yet."; }elseif ($fetch->last_race < time()){ First off I know this will be a problem with my code but I honestly have looked at it for too long. If anyone can shed a bit of simple light on it that would be great. $count should return about 8 or 9 or so but just returns 1 - I can only print out the number 1 if I do a direct echo of the mysql_num_rows() instead of putting it into the $count variable. Its really confusing, the database is all set up correctly as earlier on in the page I get all the information from the database and print out a table with it. There is something wrong here! Problem only occurs when $count = mysql_num_rows($result1); is written. Code: [Select] //Following user presses button with name applyChanges. if(isset($_POST['applyChanges'])) { $result1 = mysql_query("SELECT * FROM music") or die ("Could not get result1"); $count = mysql_num_rows($result1) or die ("Could not count rows"); //Changed this to an echo without $count and prints a 1. - Should be greater than 8 echo "$count"; for($i=0; $i<$count; $i++) { $query2 = "UPDATE music SET name='$name[$i]' WHERE path='$path[$i]'"; $result2 = mysql_query($query2); } } Thanks, Matt I have a HTML dropdown list which is populated from a MySQL table. I use an auto-incremend ID field. I have also got a sort_order field. I would like to be able to specify the exact order that entries should appear in the dropdown list. Specifically I need some functionality that does the following two things: 1) If I change the sort order of a record to for example "4" then the existing record with sort_order 4 becomes 5, sort_order 5 becomes 6 and so on. 2) If I change the sort order of a record to for example "4" and there is currently no record with sort_order 4, then no other records will be updated. |
