PHP - Is This A Good Idea?
I was wondering if this is faster or better performance.
Each time a user submit's a post on my forum I will make it +1 the .txt file on my main server directory called test.txt, then I can just call that on my main forum index to show the amount of total posts our board has, instead of using mysql queries to sum all of it from the tables... good idea? or am i retarded? Similar TutorialsThis topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=305934.0 I have a class "Login" that handles login, registration, checking if someone's logged in and authorization stuff. I would prefer to be able to instantiate this just once per session and then reuse that. however, I don't know if there's drawbacks to storing this object in the session. For example, will this lead to too much memory usage of the session object? Is it slow to keep retrieving an object from session? Would it be faster and better on the server to just re-instantiate and then destroy the object every page request? Hi First of all, I know VERY little about PHP, The effort below is a wile guess that has gone wrong. I get this error Parse error: syntax error, unexpected T_IF in /home/repairyo/public_html/shop/includes/content/viewOrders.inc.php on line 57 I have no idea what ive done wrong, may be I am stupid for attempting it. Cheers Paul This is the original code Code: [Select] $view_orders->assign('VAL_STATE',$lang['glob']['orderState_'.$orders[$i]['status']]); This is the modified code Code: [Select] $view_orders->assign('VAL_STATE',$state = $results[$i]['status'] if ($state == '1') { "<font color='#ff9900'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else if ($state == '2') { "<font color='#009900'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else if ($state == '4') { "<font color='#cc0000'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else if ($state == '5') { "<font color='#cc0000'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else if ($state == '6') { "<font color='#cc0000'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else if ($state == '7') { "<font color='#ff9900'>".$lang['glob']['orderState_'.$results[$i]['status']]."</font>"; } else { $lang['glob']['orderState_'.$orders[$i]['status']]); } I have a dropdown list where the values are retrieved form the mysql the dropdownlist is coded in php as below: $data = mysql_query("Select * From Project"); echo "<select name = 'Project' onchange = 'showUser(this.value)'>n"; while ($row = mysql_fetch_assoc($data)) { $id = $row['Project_Id']; $ProjectName = $row['ProjectName']; echo "<option value = $id>$ProjectName"; } echo"</select>"; echo "<br/>"; echo "<br/><div id='txtHint' style='width:30em; margin:0 auto;'></div><br/>"; this dropdownlist will retrieved the names of PROJECTS available in the database. when the user click any of the rpojects, it will displayed the engagements that belong to the selected PROJECT. This is also retrieved and display in a dynamic table using ajax. i have created a javascript function as below: <script type="text/javascript"> function showUser(str) { if (str=="") { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","try.php?q="+str,true); xmlhttp.send(); } </script> function showUser is placed in the "<select name = 'Project' onchange = 'showUser(this.value)'> my question is, is it possible that i display the data retrieved in the tables as hyperlinks? I want the user to be able to view the informations of the displayed engagements in another php page. the user can view the informations when they clicked on the hyperlinks of the engagement name that is displayed. the sample of table can be seen in the attachment. any idea on how to do this. Let me know cause im stuck HI, I'm writing a auction website .in auction website we need to check for new information every second so it needs to be ajax. we have a timer which calculate the end time of every auction and it needs to be updated every second.Do you have any idea for reducing the process of calculating maybe a client side but something that is updated by server? I mean , the timer works with client side and when the users BID , the timer needs to be refresh.So every time that Bid button hilted the time should be refresh. What's you idea?How can do something like that? Thanks So if I wanted to make sure my users were logged in, and had cookies & JavaScript enabled would this work...? Users enter site at index.php which sets a test cookie and calls itself (header location self in other words) if the test passed the user is redirected to the main page, if not then redirected to a page that has a we need cookies enabled page. Once in the main pages the cookie is checked and if present all good if not send back to index. Then I use session variables to track user data. I see this in my head but I'm not sure it works like I think and I am not sure how to code it. Your feedback would be greatly appreciated, and any pointers in how to code it would be prized as it would help me learn more so I don't have to ask next time.

I'm building a game and I'm wanting to create mobile monsters for people to click on and fight. I have an arena that works fine, but I would love to have this additional feature. Here's what it would entail: Clicking on the name of the monster. Starting the fight (which is already designed and implemented) I need help with: Is there a way to make a mobile link, essentially. The monsters themselves are identified in a mySQL database with a specific ID. In the arena, the players click on a monster, and the battle begins. So, I need a way to make this "link" mobile. Thoughts? Ideas? Suggestions? Thanks! A few friends of mine run a little competition between ourselves for a bit of fun. This has been in the past, a sports prediction spreadsheet where we predict the outcomes of champions in various football leagues around the world.
Up to now its always been a very laborious spreadsheet with that my friend can no longer be bothered to do.
is there any way I can do this in php / html?
There would be 8 players predicting the outcome of 6 leagues. We award points for who gets the most, half points for coming close etc.
Any ideas as to what way to approach this would be appreciated. I amvery proficient in HTML and CSS, but a bit of a novice in PHP......but if there is a script or some idea to get this up and running I would be very appreciative.
Thanks
Hi guys, I have a little issue, I have already got a quiz, here is some of the code from the quiz.

I have everything working in terms of the log in but as far as this page goes i really have no idea how i would start with it. If your not sure what i mean i can put it this way to make it much more understandable. If my page had the numbers 1 through to 49 listed down the side and next to each number it says as default "availible", but if the user click on that number the text next to that number changes from "availible" to the users username and no one others can click on that number as its "seat" or "number" has been taken. My users are stored within a mysql database and my site uses sessions like so: $_SESSION[username] = $row[username]; Many thanks for your help
Hi guys, thanks Hi I know my title doesn't give any information but I really have no idea what my problem is. The problem I have is that for some reason my code just stopped working, it was working fine in the beginning and then all of a sudden I'm getting undifined index: item, and I'm not sure what it was that I did wrong since it was working fine in the beginning. Can someone please help because this has me confused Thank you i'm trying to create a page whereby a user clicks a link from a menu on the side, and the main content of the page changes to content relating to the link, without leaving that page. i know you can do this using html frames, but as frames are rarely used anymore, i wanted to use php instead. Does anyone know how i could approach this? Thanks hi i hv built a small posting system, i hv built few categories like this in mysql i hv these tables Categories table: id catname Post Table: id postbody posttile date catid so i am getting posts with catid for related posts like http://localhost/site/index.php?action=category&cat=1 so where $_GET['cat'] is 1 it display posts from that category 1, now what i need is when i post a new post i hv choice to assign multiple categories to one post, so a post could be in cat1 and in cat2 as well . please any idea how can i do that? i was thinking to make a new rows in posts table for each category and set it to 0 or 1 , and when i submit new post it will set 1 to those categories which i select upon writing post. but if i have like 20 categories i need to add more 20 rows in posts table. is there any other better way i can accomplish this? Thanks for help OK here is what I have going on right now. Currently I'm trying to build a excel spread sheet into a dynamic form via php. The results are basically questions and are stored each week so for one section they may be asking how many visitors, employee's , etc.. now some of these values that are being entered are going to be used in another question per-say but the result may come from other values that were already submitted so these questions would not be shown in the form that needs to be made later on. The form I'm having trouble with is the initial form to help generate the formula's for these different questions. So what I was going to start doing was have it list all the questions with a check box next to the question if the formula for said question was something like add these two questions and the divide by this set of questions or a whole number then it would display a list of questions for adding together and the get the total from that set and then do a expression afterwards like adding, subtracting, multiplying or dividing. So I was thinking I should list like a set of buttons I think in the beginning. What is the first task at hand Totaling, Adding, Subtracting, Dividing, Multiplying and then when they click on this it would refresh the page and bring up a box that lists all the different questions for them. Then saving the values as which ever button they clicked and once they do this. Then they could either click on say a more button which would pass the values as a array back to the page and continue on or they could click submit and pass the values into a db field as a formula but this is my first concept and would like to know if there may be a better way of doing it. I can't honestly see whats wrong with this code, it's print'ing correct with the print_r. Code: [Select] Array ( [value1] => 2 [option] => - [value2] => 1 ) however i can't actually echo out the value1,value2 or option? It says the vars are empty yet it can still print_r the values so i know there not empty Code: [Select] <?php if(isset($_POST["submit"])){ $value1=$_POST["value1"]; $value2=$_POST["value2"]; $option=$_POST["option"]; } print_r($_POST); echo"$value1"; ?> <form action="index.php" name="submit" method="post"> <input type="text" name="value1"> <select name="option"> <option>+</option> <option>-</option> <option>*</option> <option>/</option> </select> <input type="text" name="value2"> <input type="submit" value="submit"> </form> I think a switch break will help in this situation but I am definitely open to suggestions The problem I am have is that if there are 2 "Funner" or "Funnest" in the database then it displays duplicates in the in the column. I know that is what the code is telling it to do. If you look at the first row it should split them if there are 2 and display one in each column. In one time slot there is only allowed: - 1 Fun - 1 Funner or Funnest - 1 Funner or Funnest The case I am working with is there is 1 Fun and 2 Funners. The 2 Funners should split and display one in each "Funner/Funnest" column. There are planty of unique identifiers if someone has an idea for me. function taken($theType, $theTime){ $day_view = $_GET['date']; $DOP = explode("-", $_GET['date']); $topDOP = date("M", mktime(0, 0, 0, $DOP['1']))." ".$DOP['2'].", ".$DOP['0']; $dayDOP = date("l", mktime(0, 0, 0, $DOP[1], $DOP[2], $DOP[0])); connect(); $sql = "select * from party_times where dates = '$day_view' and paidID ='paid' and times = '$theTime'"; $result = mysql_query($sql) or die(mysql_error()); $day_count = mysql_num_rows($result); while($info = mysql_fetch_assoc($result)){ if($info['type'] == "$theType" && $info['times'] == "$theTime"){ $conID = "select DISTINCT confirmID from party_receipt where partyID = '".$info['partyID']."'"; $conqu = mysql_query($conID) or die(mysql_error()); while($con = mysql_fetch_assoc($conqu)){ $cid = $con['confirmID']; echo "<a href='party_booked.php?view=$cid'>RESERVED</a>"; }free($conqu); } }free($result); } Call the function: Code: [Select] <tr> <td width="25%"></td> <td width="25%" align="center">Fun</td> <td width="25%" align="center">Funner / Funnest</td> <td width="25%" align="center">Funner / Funnest</td> </tr> <tr> <td>11:00 AM</td> <td class = "res"><?php taken("Fun", "11:00 AM"); ?></td> <td class = "res"><?php taken("Funner", "11:00 AM"); ?></td> <td class = "res"><?php taken("Funnest", "11:00 AM"); ?></td> </tr> Thank you! |
