PHP - Tables ? I Think I Have It Mysql
just trying to see if i have this right in my head here..
if i have a page that has a topic on it and many replies, the tables would look like this.. would this be the right code to pull out the topic AND all responses for say. www.mysite.com/view?id=1 $topic = 'SELECT * from topics where id = $id' $replies = 'SELECT * from replies where replies.topic_id = $id' Similar TutorialsThis portion is kind of stumping me. Basically, I have a two tables in this DB: users and users_access_level (Separated for DB normalization) users: id / username / password / realname / access_level users_access_level: access_level / access_name What I'm trying to do, is echo the data onto an HTML table that displays users.username in one table data and then uses the users.access_level to find users_access_level.access_name and echo into the following table data, I would prefer not to use multiple queries if possible or nested queries. Example row for users: 1234 / tmac / password / tmac / 99 Example row for users_access_level: 99 / Admin Using the examples above, I would want the output to appear as such: Username: Access Name: Tmac Admin I am not 100% sure where to start with this, but I pick up quickly, I just need a nudge in the right direction. The code I attempted to create just shows my lack of knowledge of joining tables, but I'll post it if you want to see that I did at least make an effort to code this myself. Thanks for reading! I need some help on how to search in two different mysql tables, and then show the results sorted/ordered by the tables. Quote RESULTS: Tabel 1 # ... # ... Tabel 2 # ... # ... Thanks in advance! 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 $row["visits"]; echo "</font></td></tr>"; } echo "</table>"; ?> <script type="text/javascript"> initSortTable('myTable',Array('S','N','S','N','S')); </script> I just found out my user ID is missing from database.. Heyyzarrh, iv been having troubles trying to make it so my PHP script will echo out the username by corresponding the posters ID with the ID in the members table. Heres what iv got so far: Code: [Select] <?php if ($urlid == "") { } $sql = mysql_query("SELECT members.username, posts.mem_id, posts.post_date, posts.post FROM members JOIN posts ON members.id = posts.mem_id WHERE posts.mem_id='$urlid' ORDER BY post_date DESC LIMIT 20"); while ($row = mysql_fetch_array($sql)){ echo '<b>' .$row['$username']. ':</b> '.$row['post'].'<br />At: '.$row['post_date'].'<br /><br />'; } ?> Please help!! :S so far only the actual posts data comes out not the username from the table "members"... Okay so I have 2 tables in my database. One called user and one called messages. A user logs in to the message board and leaves a message (eg nice website). They write in the author name and the message then after the message is posted it says "Nice website" Posted by (author) on (date). All is good so far. It works. However if you look at my code you will see I have a session started. This session is storing the username of the logged in user. From the column username in the users table. (This table has has an id for each user). Ive played around with the code trying to make it so the user doesnt have to fill in the author box. I want rid of that box So the logged in user just leaves a message then it says "posted by (username) on (date). Im missing something from my code. Can anyone tell me what? Please? <?php session_start(); mysql_connect("*************", "*****************", "***************"); mysql_select_db("***********************"); $time = time(); //this checks to see if the $_SESSION variable has been not set //or if the $_SESSION variable has been not set to true //and if one or the other is not set then the user gets //sent to the login page if (!isset($_SESSION['username'])) { header('Location: http://***************.com/login.php'); } $query = "INSERT INTO messages VALUES( NULL, '". mysql_real_escape_string($_POST['message']) ."', '". mysql_real_escape_string($_POST['username']) ."', '$time' )";if( $result = mysql_query($query) ) { if(mysql_affected_rows() > 0 ) { echo "Message Posted.<br><a href='messageboard.php'>Return</a>"; } else { echo 'There was an error posting your message. Please try again later.'; } } else { echo "There was a database error."; // comment out next line for live site. echo "<br>Query string: $query<br>Returned error: " . mysql_error() . '<br>'; } ; $sql = "SELECT * FROM leads WHERE accesstoken = '".$_POST["userAc"]."'"; $result = mysql_query($sql) or trigger_error("Query Failed: " . mysql_error()); if(mysql_num_rows($result)>0) { while($row = mysql_fetch_array($result)) { $id= $row['id']; $fullname= $row['fullname']; $email= $row['email']; $to = $email; $message .= $_POST["userMessage"]; $subject = $_POST["userSubject"]; $headers = "From: " . $_POST["userEmail"] . "\r\n"; $headers .= "Reply-To: ". $_POST["userEmail"] . "\r\n"; $headers .= "MIME-Version: 1.0\r\n"; $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; if (mail($to, $subject, $message, $headers)) { $output = json_encode(array('type'=>'error', 'text' => '<p>Your Message was sent successfully!</p>')); die($output); } else { $output = json_encode(array('type'=>'error', 'text' => '<p>Your Message was not sent!</p>')); die($output); } } }I have another table called accounts that I want to join with this one, I need to select from ref to get the email from account table also! be something like this $sql = "SELECT * FROM accounts WHERE ref = '".$_POST["userAc"]."'"; $result = mysql_query($sql) or trigger_error("Query Failed: " . mysql_error()); I have looked all over the net on how to fix this... I am creating a baseball statistical website and I have 2 tables with identical columns (2012hitting and 2013hitting). I am trying to create a page where I can 1) group each year's statistics (which I have been able to do) and 2) have a row named "Career Totals". Each table has about 15 columns, various stats. How can I add the data from my 2012hitting table to my 2013hitting table into a Career Totals row for each player? This is what I'm trying now: Code: [Select] /* CONNECTION VARIABLES */ $id = $_GET['id']; // get var from URL /* Get data. */ $sql = "SELECT * (sum(2012hitting.hr) +sum(2013hitting.hr)) as totalhr FROM 2012hitting, 2013hitting WHERE id='$id'"; $result = mysql_query($sql); ?> <?php $alternate = "2"; while ($row = mysql_fetch_array($result)) { $field1 = $row["season"]; $field2 = $row["team"]; $field3 = $row["games"]; $field4 = $row["ave"]; $field5 = $row["slg"]; $field6 = $row["r"]; $field7 = $row["h"]; $field8 = $row["rbi"]; $field9 = $row["bb"]; $field10 = $row["k"]; $field11 = $row["hr"]; $field12 = $row["dbl"]; $field13 = $row["tpl"]; $field14 = $row["sb"]; $field15 = $row["obp"]; $field16 = $row["ops"]; if ($alternate == "1") { $color = "#ffffff"; $alternate = "2"; } else { $color = "#E4E4E4"; $alternate = "1"; } echo "<tr bgcolor=$color><td align='center'>$field1</td><td align='center'>$field2</td><td align='center'>$field3</td><td align='center'>$field4</td><td align='center'>$field5</td><td align='center'>$field6</td><td align='center'>$field7</td><td align='center'>$field8</td><td align='center'>$field9</td><td align='center'>$field10</td><td align='center'>$field11</td><td align='center'>$field12</td><td align='center'>$field13</td><td align='center'>$field14</td><td align='center'>$field15</td><td align='center'>$field16</td></tr>"; } echo "</table>"; ?> Thank you in advance! I'm creating a staff directory that I'd like to use alternating background colors (odd/even) to make it easier to read. All of the information is stored in sql, which I can pull to the page with a repeat function, but I'm not sure how to get the zebra effect to alternate with the output. Is there any easy way to do this? I'm using CSS to change the background of the table itself. Code: [Select] <table width="100%" border="0" cellpadding="1" cellspacing="0" class="staff_b"> <tr> <td width="35%"><div class="staff_h">Name</div></td> <td width="35%"><div class="staff_h">Department</div></td> <td width="30%"><div class="staff_h">Extension</div></td> </tr> <tr class="staff_e"> <td>1</td> <td>2</td> <td>3</td> </tr> <tr class="staff_o"> <td>4</td> <td>5</td> <td>6</td> </tr> </table> I have two tables in which different information of members are stored... table 1 stores the users main info, name, city, category, location table 2 stores extra info such as sub categories of items they have. Now i want to be able to search both tables for one value...say i type in red..i want to be able to search both tables at the same time to find the results and display them So far i'm stuck in figuring out how to do this, which is why i'm asking for help now. Hope someone can give me some guidance Hi, So I'm trying to make a car rental project, and I need to show cars of a specific type, available in a specific period. I'm currently using this query: SELECT * FROM car, reservations WHERE car.car_id = reservations.car AND car.type = 1 AND reservations.reserved_from >= "2011-12-22" AND reservations.reserved_to <= "2012-12-20"; So this returns all the cars of the type 1 reserved in 2011-12-22 - 2012-12-20 period. So know that I know which cars are unavailable, how would you go ahead and pick out what's left? month a0 a1 a2 a3 a4 a5 a6 a7 a8 a9 a10 a11 a12 a13 a14 a15 a16 a17 a18 a19 a20 a21 a22 a23 a24 a25 a26 a27 a28 a29 a30 a31 1 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 [20] [21] 22 23 24 25 [26] 27 28 29 30 31 2 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 3 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 4 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 5 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 6 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 7 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 8 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 9 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 10 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 11 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 12 puudu 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 ; i need help .. with calculating how many days are between example: january = 1 ; day =23 to feb =2; day 23 in php ... how can i do that so I'm trying to change some specific columns in a row in a table of a MySQL database by calling the Doctrine_Query when an option is selected inside an admin panel of my website.

Sorry in advance, I'm not very good with PHP yet. i have two tables, employee details table(empno, emp_name , branch) and attendance table(date, Ot, attendence). I want to create a relation between two tables Hi Guys, I need a little help. This one is giving me a real head ache :-( I have created a archive database in mysql. Within the database there are tables named YYYYMMDD_var. The tables layout is as follows: #################################### node + T00 + T03 + T06 + T09 + T12 + T15 + T18 + T21 #################################### I have created some drop down menus in php to call for the dates Dateto and Datefr. I then calculate the diff between the dates and return the output (20101101_var, 20101102_var etc,,,) But when I call for the mysql Select I cant get all tables :-( This is the following code I have been using, starting from getting requesting the dates from the drop down menus. The problem lies in the UNION, where because it's caught in the loop, it returns it at the end of the line. Which creates the error. If anybody has any other ideas, please help :-) //dates from $dayfr = $_REQUEST['dayfr']; $monthfr = $_REQUEST['monthfr']; $yearfr = $_REQUEST['yearfr']; //dates to $dayto = $_REQUEST['dayto']; $monthto = $_REQUEST['monthto']; $yearto = $_REQUEST['yearto']; $var = $_REQUEST['var']; //cacluate the diff function days($date1, $date2){ $month1 = date("m", strtotime($date1)); $day1 = date("d", strtotime($date1)); $year1 = date("Y", strtotime($date1)); $month2 = date("m", strtotime($date2)); $day2 = date("d", strtotime($date2)); $year2 = date("Y", strtotime($date2)); $first = gregoriantojd($month1, $day1, $year1); $second = gregoriantojd($month2, $day2, $year2); $diff = abs($first-$second); return $diff; } $date1 = "$yearfr-$monthfr-$dayfr"; $date2 = "$yearto-$monthto-$dayto"; $days = days($date1, $date2); for($i=0; $i<$days; $i++){ $newdate = date("Ymd", strtotime("$date1 +$i days")); $datevar="$newdate$var ,"; $getdata="SELECT * FROM $newdate$var WHERE node='1' UNION "; echo "$getdata"; } //NOW SELECT OUR TABLES FROM THE ARCHIVE DATABASE $data=mysql_query("$getdata") or die(mysql_error()); Not sure if this topic goes in here, it is related to PHP but also MySql, so if i'm on the wrong board sorry! What i'm trying to do is search for a keyword in 5 different tables and return the keyword ID from the table that its in The tables i'm trying to search are as follow location state county region continent The "location" table has all the locations i.e cities and each row has the following columns: id | continent_id | country_id | state_id | region_id | city_name The "state" table is set the the following: id | name "county" table : id | name "region" table: id | region and "continent" table id | name The way it works is the can search for any city or state or county or region or continent and ideally it should look into the five different tables and return the id of that table. So if the use searches for United States it will look for United States in all five tables, obviously it would find it in the "country" table so it should return that "id". The results are returned in "json format" Below is the code i have: Code: [Select] <? $input = $_GET['keyword']; $data = array(); /* In this query i'm attempting to search in all databases, but i'm not sure if i'm doing this right. I'm not getting any results so i know something is wrong just don't know how to write it. */ $query = mysql_query("SELECT * FROM locations JOIN states ON states.id = locations.state_id JOIN countries ON countries.id=locations.country_id JOIN regions ON regions.region_id = locations.region_id JOIN continents ON continents.id=locations.continent_id WHERE name LIKE '$input%' OR state LIKE '$input%' OR region LIKE '$input%' OR country LIKE '$input%' OR continent LIKE '$input%'") or die(mysql_error()); /* Here the values are added to to the $json array. The "value" should be the "id" from the table that the keyword matched. The 'name' Should be the name of the actual keyword. Again if they search for United States the "id" will come from the "countries" table and the "value" would come from the "countries" table as the name */ while ($row = mysql_fetch_assoc($query)) { $json = array(); $json['value'] = $row['id']; $json['name'] = $row['name']; $data[] = $json; } header("Content-type: application/json"); echo json_encode($data); ?> Any help would he be appreciated, i don't want people to do it for me, but rather just guide me a little bit.

P.S - Will it be possible, by creating a random function in PHP which will check for repeat questions in a session and check for the 'id' of the question and if it is new display it on the page. If so what should I do and if no then how to do? Guys, quick one. Im writing a script for a form to post info into a MySql table. Now rather than just having a single row for input I'd like to have lets say 10 rows, so I can add 10 records to the database. What I'm pondering is 2 things: 1: can i just repeat Code: [Select] <input type="text" name="opponent" size="27" /> over and over, or is it going to need its own name each time for example; Code: [Select] <input type="text" name="opponent2" size="27" /> <input type="text" name="opponent3" size="27" /> 2: when it comes to the processing script is it more economical to have the forms input field named the same over and over (if it IS possible) and if not whats the most econimcal way to code my Code: [Select] $opp= $_POST['opponent']; $query="INSERT INTO fixtures (match_date, season, opponent) VALUES ('$date', '$season', '$opp',)"; Your help and comments are appreciated as always guys Tom |
