PHP - Display Records From A Db At Different Time Intervals
Hello Everyone, I wanted to know how to Display records from a Table one by one at difference time intervals. Kindly suggest
Similar TutorialsHello guys. I am creating a PHP/mySQL based RPG. I have implemented training feature in it. So i want to make training possible every 15 minutes or so. Can you give me an advice how to achieve that? Thank you! I am having trouble showing reports for a given date range. Currently if I specify something like 11/03/2010 to 11/05/2010 I get results for all years within that month and day such as I may get results for 11/03/2008 11/03/2009 11/03/2010 11/04/2008 11/04/2009 11/04/2010 11/05/2008 11/05/2009 11/05/2010. I am using the following code $result = mysql_query("SELECT * FROM report WHERE date>='$date_begin' and date<='$date_end' ORDER BY 'date'",$db); I use the following format in my date feild mm/dd/yyyy My script is finally working as intended, but I want to add some additional data results. I am trying to resolve how I can display a count of ONLY the records updated by my query: // START :: Query to replace matches mysql_query("UPDATE orig_codes_1a AS a JOIN old_and_new_codes_1a AS b ON concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2) SET a.orig_code_1 = b.new_code_1, a.orig_code_2 = b.new_code_2") or die(mysql_error()); // END :: Query to replace matches In this query I count ALL records selection: // START :: Create query to be displayed as final results of original codes table. $result = mysql_query("SELECT * FROM orig_codes_1a") or die(mysql_error()); I want to display a count on this part of the query: ....concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2).... I am trying to make automated scoresheets for a soccer league. The problem i am having is it is only displaying the first record and repeating. Could someone please help me out with this? Thanks in advance. Code: [Select] <?php /* connection and protection */ include 'dbc.php'; // MATCH DATA $details = mysql_query("SELECT * FROM thirdsched_south WHERE id = '1'") or die(mysql_error()); // matchs data $match = mysql_fetch_array( $details ); // HOME TEAM $hometeam = mysql_query("SELECT * FROM players WHERE teamid = 'cloverda' AND approved ='1'") or die(mysql_error()); // store home data $home = mysql_fetch_array( $hometeam ); // AWAY TEAM $awayteam = mysql_query("SELECT * FROM players WHERE teamid = 'lefcb' AND approved ='1'") or die(mysql_error()); // Store AWAY DATA $away = mysql_fetch_array( $awayteam ); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript" src="public_smo_scripts.js"></script> <link href="styles.css" rel="stylesheet" type="text/css"> <style type="text/css"> <!-- .style1 { font-family: Geneva, Arial, Helvetica, sans-serif; font-size: 13px; } .style2 {font-size: 14px} .style3 {font-family: Geneva, Arial, Helvetica, sans-serif; font-size: 14px; } --> </style> </head> <body onload="window.print()"> <table width="930" border="1"> <tr> <td colspan="2" class="style1 style1"><div align="center"><img src="bccsl-gmsh-hd.jpg"/></div></td> </tr> </table> <table width="930" border="1"> <tr> <td width="455" class="style1 style1"><div align="center" class="style2">Division: Third- South</div></td> <td width="459" height="32" class="style1 style1"><div align="center" class="style2">Date: <?

Hello, I am trying to display rainfall totals for the year so far in a table with months going across and days going down. Like so: -- Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 1 2 3 4 5 6 7 8 etc And then have the rainfall totals for each day in the table, I am quite experienced with PHP however I cant work out how I would do this The data is stored in a mysql table called "wx_daily", and the rainfall column is called" RainTotal". The dates are stored in the "Date" column in mysql Date format. Im using the following mysql query: SELECT * FROM wx_daily WHERE YEAR(Date) = '2011' ORDER BY Date Asc Thanks, Mark I have several forms which will request the user to select one of several options where the most common choices will be pronounced, and might look something like: Select Option A Select Option B Select Option C Select Option D Click here for more choicesThe client is responsible to determine which ones to display (opposed to hiding within "more choices") and the server is responsible to provide the list of options along with some means to determine which ones are most common. For a new user, the order will be based on my "best guess", however, whenever a user selects a given option its ranking for that user only should go up, and in addition more recent activities should have more bearing on the returned order. In addition, there will be more than one of these lists and each of these lists will expose a public identifier (most will use a string but some might use an incrementing integer series) instead of the primary key. I have some fragmented ideas how to best implement but would like other people's thoughts on how to best do so. Starting with the list schema, undecided on which approach below. Any preferences or something else altogether? Solution 1: abstract_list - id (INT PK) - discriminator (string) - name (string unique with discriminator) - ranking (TBD whether float or integer. This represents my initial "best guess") list1 (list2, etc) - id (FK to abstract_list.id) - discriminator (FK to abstract_list.discriminator) - public_id (string or integer based on specific list. unique with discriminator) Solution 2: abstract_list - id (INT PK) - discriminator (string) - name (string unique with discriminator) - ranking (TBD whether float or integer. This represents my initial "best guess") - public_id (Application responsible to cast as string or integer. unique with discriminator) list1 (list2, etc. This class has no properties and only a method to cast the public ID as required. Seems like a waste...) - id (FK to abstract_list.id)
user_list_ranking - abstract_list_id - user_id - ranking (TBD) To retrieve the list options, will query abstract_list and LEFT JOIN user_list_ranking and then sort on some mathematical formula acting on abstract_list.ranking and COALESCE(user_list_ranking.ranking, 0). To promote recent activity, maybe increment user_list_ranking.ranking every time the user selects a given option and also decrement all other options of the associated list. To prevent excessive windup, cap the the value to some max value (i.e. If list1 has a total of 10 records, cap it three times that value resulting in 30), and cap the minimum at zero. Uncharted territory here and am very open to other approaches. I am undecided whether I should just return an ordered array of the options, or also include either an order integer or some normalized value from 0 to 1. If there is a common way to do this, please let me know what it is so I may mimic it. If not, please provide any critique or recommended changes to my intended approach. Thanks Hey guys, How would I go about subtracting Today from a previous day to find the difference? For example, I want to subtract TODAY from a previous date in my database, to determine if the difference is greater than 1 day. Any ideas? I tried doing the subraction in TIMESTAMPS, but when I convert the date back to Y-m-d H:i:s, I got some weird year and time. At the moment I have: $month_end_date[$surgeryinvoicescount]=$i[0]; = 2011-04-13 I would like $month_end_date[$surgeryinvoicescount]=$i[0]; = 13/04/2011 I have tried the following but didn't work?!: $month_end_date = date('d/m/Y',strtotime($month_end_date)); $month_end_date[$surgeryinvoicescount]=$i[0]; I am trying to display "open" / "closed" depending on the time of day. I tried to write my own script but it doesn't seem to be working. Does anyone know of some boxed script I can use? Here is what I have... function open(){ $AMPM = date('A', time()); if ($AMPM == "PM"){ connect(); $day = date('l'); $sqlcurrent = "select * from hours where day = '$day' and closed ='1'"; $currently = mysql_query($sqlcurrent) or die(mysql_error()); $checkDay = mysql_num_rows($currently); if ($checkDay == "1"){ while($getID = mysql_fetch_assoc($currently)){ $convertopen = strtotime($getID['open']); $convertclose = strtotime($getID['close']); $displayTimeH = date('H', time()); $displayTimeM = date('i', time()); $displayTimeAMPM = date('A', time()); $opentime = explode(":", $getID['open']); $openhour=$opentime[0]; $openminute=$opentime[1]; $closetime = explode(":", $getID['close']); $closehour=$closetime[0]; $closeminute=$closetime[1]; //echo "$closehour$closeminute<br />"; //echo "$displayTimeH$displayTimeM<br />"; if (($openhour <= $displayTimeH && $openminute <= $displayTimeM) && ($closehour >= $displayTimeH && $closeminute >= $displayTimeM)){ echo "We're Open ... Come On In!"; }else{ echo "Hours of Service"; } } }else{ echo "Hours of Service"; free($currently); } }else{ echo "Hours of Service"; } } // close function I know it's brutal but it's all I could come up with... Tried to use a datetime addition function but it gave me this error: Quote Fatal error: Call to undefined function date_add() in /home2/cruxispr/public_html/mysidiaadoptables/devdemo/script.php on line 3 I searched on PHP tutorials, but it says there's no need to install any of these datetime related functions since they are part of PHP core. I dont understand, why do I get a no method error like this if it is indeed already in PHP core? Please help. Here are the links from PHP official site for references: http://www.php.net/manual/en/datetime.installation.php http://www.php.net/manual/en/datetime.add.php I'm stuck on how to only display records if they are in the last 3 days: how do i say: if $row['test_date'] occurred more than 3 days ago: don't display. else, display. Thank you :-) This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=314226.0 Hey all. I have a query that selects data from a datbase based on a criteria. Easy enough. But now I am growing and the amount displaying is too much. How can you, via php, have a queries result be displayed only so many at a time and auto create links that show the rest? Like if query returns 82 results, I want it to display 25 immediately and create 3 links at the bottom. The next link would show 26-50. The next 51-75. And the final 76-82. etc Example: Code: [Select] $result = mysql_query("SELECT * FROM pay"); $num_rows = mysql_num_rows($result); while($row = mysql_fetch_array($result)) { echo $row['first_name']; echo $row['last_name']; echo $row['item_name']; echo $row['option_selection1']; echo $row['payment_date']; echo $row['stat']; } This is simple. But what happens when the results are 125? I want to limit it to displaying 25 at a time. Is the only way to manually create seperate pages and have each one show 1-25, then 26-50, etc? Or is there a way to have the script do it, itself? Any tutorials out there on this specifically? Hopefully I am making sense. Thanks! I'm interested to know how other people keep track of time and also how they display time correctly back to the users. I'm using a third party API that I can tie into that actually gives me the userID of a user, their full name and the timezone for that user. After checking a few users data, this is an example data of what I'm working with. userID: 234213412 first_name: foo last_name: bar timezone: -6 Basically when a user visits my web app, I create a new account for them and store the above data. Currently, I'm just fetching the result from time() and converting it into MySQL DateTime format and storing that into my database. Code: [Select] //get the current time as an integer $php_timestamp = time(); //formats the time according to MySQL DateTime type $this->mysql_formatted_time = date('Y-m-d H:i:s', $php_timestamp); I would think the current way that I'm doing this is not very good because there is a possibility that I could introduce load balancing servers into the mix and they might not be located in the same region. Also, I would have no idea how to factor the time and modify it according to the timezone value.(in my above example, -6) Can anyone help me decide what method I should use to keep all of my servers timestamps in sync and how to display the time to the end user so that it looks correct to them? This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=321950.0 If there are two DataTime's which are exactly X seconds apart and the difference between those two DateTime's is added to a third DateTime, then the third DataTime's timestamp would change by exactly X seconds, true? Then why doesn't the second test below show those results, but is off by 1 day?

hi all please help... i would like to get datas between certain intervals. please have a look @ db_table.jpg, it's the db structure. the red highlighted part is the value i need. condition is select values when both device one & device two are off. db_table_report.jpg is the resulting report format. It contains start time & end time and the duration.. please help, i know it's a bit complicated, but it's urgent. |
