PHP - Php Mysql Table Loop
I am trying to place a unique number into a mysql table.
Currently, my code generates a random number, then is supposed to scan through the table for that number. If the code finds that number already in the table, it generates a new random number and repeats the process. I have commented my code for the purpose of this help forum: Code: [Select] $result = mysqli_query($link,"SELECT * FROM testTable"); do { $end = true; //prepares end of loop $idNum = rand(1,10); //rand(1,999999); <-- for testing purposes I have reduced the number generated $idNumTx = (string)$idNum; //loop through the rows while ($row = mysqli_fetch_assoc($result)) { if ($row['idNum'] = $idNum) //check if the random number equal to this row { $end = false; //prep end of loop repeat echo $idNumTx; //display rand number that failed for testing purposes echo " NO! "; //display error for testing purposes } } } while(!$end); I know I must be doing something wrong, as when I run this, it runs the if statement within the while loop always executes, and I get an output like: Code: [Select] 1 NO! 1 NO! 1 NO! 1 NO! 1 NO! 1 NO! 5 Win Win is when it places the value before it, in this case 5, into the table. However, the value of 5 might already be in the table and it doesn't seem to matter. I execute the code multiple times, and it seems to increase the number of "# NO!" almost (but not every) time. However, each time ALL of the "# NO!" are the same #, and the "# Win" just seems to be random (as it should be, but not unique). Checking the table after shows me random numbers between 1 and 10 (as it should) in the correct field, but the are not unique. (Ex/ Both row 1 and 5 could have the same value, say 6) I'm hopefully doing something simple wrong, so someone please point it out to me Similar TutorialsThis way seems not good. <?php $username ="MANCENT"; $user_input_x = _xmouse.movement ;//FLASH $user_input_y = _ymouse.movement ;//FLASH while(true) { $updatepos = mysql_query("UPDATE users_float SET user_input_x = '$user_input_x' , user_input_y = '$user_input_y' WHERE username = '$username'"); } This way works but whats a better way? ?> I want to loop through a MySQL table, and perform a calculation based on the current row the loop is on and the previous loop. Say my table has 2 columns - Film_id and FilmRelease, how would I loop through and echo out a calculation of the current FilmRelease and the previous row's column value? Thanks guys I have got to this stage, but for some reason it's not printing out anything Code: [Select] <?php mysql_connect("localhost", "****", "*****") or die(mysql_error()); mysql_select_db("*****") or die(mysql_error()); $sql = mysql_query("SELECT FilmRelease FROM Films_Info") or die(mysql_error()); $last_value = null; while ($row = mysql_fetch_assoc($sql)) { if (!is_null($last_value)) { print date_diff($row['FilmRelease'], $last_value) . "<BR>"; } $last_value = $row['FilmRelease']; } Hi
I am very new to PHP & Mysql.
I am trying to insert values into two tables at the same time. One table will insert a single row and the other table will insert multiple records based on user insertion.
Everything is working well, but in my second table, 1st Table ID simply insert one time and rest of the values are inserting from 2nd table itself.
Now I want to insert the first table's ID Field value (auto-incrementing) to a specific column in the second table (only all last inserted rows).
Ripon.
Below is my Code:
<?php $con = mysql_connect("localhost","root","aaa"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("ccc", $con); $PI_No = $_POST['PI_No']; $PO_No = $_POST['PO_No']; $qry = "INSERT INTO wm_order_entry ( Order_No, PI_No, PO_No) VALUES( NULL, '$PI_No', '$PO_No')"; $result = @mysql_query($qry); $val1=$_POST['Size']; $val2=$_POST['Style']; $val3=$_POST['Colour']; $val4=$_POST['Season_Code']; $val5=$_POST['Dept']; $val6=$_POST['Sub_Item']; $val7=$_POST['Item_Desc']; $val8=$_POST['UPC']; $val9=$_POST['Qty']; $N = count($val1); for($i=0; $i < $N; $i++) { $profile_query = "INSERT INTO order_entry(Size, Style, Colour, Season_Code, Dept, Sub_Item, Item_Desc, UPC, Qty, Order_No ) VALUES( '$val1[$i]','$val2[$i]','$val3[$i]','$val4[$i]','$val5[$i]','$val6[$i]','$val7[$i]','$val8[$i]','$val9[$i]',LAST_INSERT_ID())"; $t_query=mysql_query($profile_query); } header("location: WMView.php"); mysql_close($con); ?>Output is attached. create table mimi (mimiId int(11) not null, mimiBody varchar(255) ); <?php //connecting to database include_once ('conn.php'); $sql ="SELECT mimiId, mimiBody FROM mimi"; $result = mysqli_query($conn, $sql ); $mimi = mysqli_fetch_assoc($result); $mimiId ='<span>No: '.$mimi['mimiId'].'</span>'; $mimiBody ='<p class="leading text-justify">'.$mimi['mimiBody'].'</p>'; ?> //what is next? i want to download pdf or text document after clicking button or link how to do that Hi, I'm in need of making some loops within each other, in order to retrieve the info which i need. First part of my code: Code: [Select] <div class="hastable"> <table id="sort-table"> <thead> <tr> <?PHP //echo '<th style="width:128px">Options</th>'; echo ' <th> Identifier </th> '; $fieldresult = mysql_query("SELECT * FROM fields ORDER BY `order`"); while($fieldrow = mysql_fetch_array($fieldresult)) { echo ' <th> ' . $fieldrow["name"] . ' </th> '; So you see, here i create all the table headers required, as long as it can still fetch some data. My problem is, that I need to execute a echo '</tr>'; when it's done fetching the data, meaning as soon as it cannot retrieve any more data, i need to close this row, as the next data coming, should be placed in a second row.. Is there any way to do this - Without exiting the loop? Anyone know why I get this from my mysql query?It adds an extra key for some reason. $types = array(); while ($row = mysql_fetch_array($query_name,MYSQL_NUM)) { $types[] = $row; } print_r ($types); Array ( => Array ( => Matt ) [1] => Array ( => Larissa ) [2] => Array ( => Braden ) [3] => Array ( => Tom ) ) Hello, I need some help. Say that I have a list in my MySQL database that contains elements "A", "S", "C", "D" etc... Now, I want to generate an html table where these elements should be distributed in a random and unique way while leaving some entries of the table empty, see the picture below. But, I have no clue how to do this... Any hints? Thanks in advance, Vero I have a while loop that is making a table 5 times for me. The issue that i am having is i need to run 5 different mysql query's for the 5 different tables that the loop is making for me. How would i go about doing this? Here is my code <? $i=1; while ( $i <= 5 ) { ?> <table width="600" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td width="414" height="35" colspan="5"><strong>Level <?=$i?></strong></td> </tr> <tr> <td height="25"><div align="center">Join Date</div></td> <td><div align="center">Member Name</div></td> <td><div align="center">Username</div></td> <td><div align="center">Free/Pro</div></td> <td><div align="center"></div></td> </tr> <? $level_one = mysql_query("select * from users where ref_by = '$username'"); while ($level_one_do = mysql_fetch_array($level_one)) { $status = $level_one_do['status']; if($status == 1) { $status_type = "Free"; } else { $status_type = "Pro"; } ?> <tr> <td height="35"><div align="center"></div></td> <td height="35"><div align="center"></div></td> <td height="35"><div align="center"> <?=$level_one_do['Username']?> </div></td> <td height="35"><div align="center"></div></td> <td height="35"><div align="center"><img src="images/email_forward-32.png" width="25" height="25"></div></td> </tr> <? } ?> </table> <? $i++; } ?> Apparently, this is bad. Wish someone would have told me. Sadly, it is too simple. I had Code: [Select] <? $company=mysql_query("select this and that") while($company=mysql_fetch_array($company)) { a bit of output; $properties=mysql_query("Select this and that from properties where company_id=$company['id']") while(properties=mysql_fetch_array()) { what I want to output } } I seem to be missing some understanding of what the heck to do now. Please, please any suggestions. I suck at object orientation, and arrays of arrays of arrays confuse the crap out of me. Am I missing something simple. Am I over-reacting? I have 15 companies, and about 100 properties total. Need some feedback on this loop Tables: Table A Table B Loop Select all from A based on criteria a. Insert into table B using row data from table A b. Update record in table A to say that it has gone through loop to prevent future loop Thats three MySQL queries running over and over at the same time, how bad is that for performance, is there another way? Maybe instead of running b each time build an array with the record ids from Table A and after the loop runs to insert into Table B run another query with the IN command to loop through all of the IDs in the array and update? I've got Code: [Select] for ($i=1; $i<=5; $i++) { if(isset($_POST['partsusedqty'.$i]) && $_POST['partsusedqty'.$i] != "" && $_POST['partsusedqty'.$i] != "0.00") { mysql_query("INSERT INTO partsused (ptnumber, partqty, partdesc, partprice) VALUES ($ticket, '$partsusedqty'.$i, '$partsuseddesc'.$i, '$partsusedprice'.$i)") or die(mysql_error()); } } I need to know the correct formatting to put these variable variables as values in the mysql query. With this particular code, I get the error "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.1, ''.1, ''.1)' at line 2" I've tried formatting this an endless number of ways, but I used this particular example because its the one I really thought should work. Everything I've tried that doesn't throw an error put the $partsusedqty in the partqty, partdesc, and partprice fields. Thanks for any help! I am a noob at php, looking to become great. My php loop only seems to draw 1 row from the database when listing it out. Here is the loop <?php require('header.php'); mysql_select_db('center'); $sql = "select username, password from users"; $result = mysql_query($sql); $row = mysql_fetch_array($result); $user = $row['username']; $pass = $row['password']; echo "<table border='1'>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>$user</td>"; echo "<td>$pass</td>"; echo "</tr>"; } echo "</table>"; ?> Hey guys, I am trying to input data into a mysql database from data thats been added by a jquery form with cloned fields. It is working however it adds the first row correctly then a blank row and then the rest of the rows correctly The code is this $x=0; do { $fga=$_POST['ID'.$x.'fga']; $fgm=$_POST['ID'.$x.'fgm']; $fta=$_POST['ID'.$x.'fta']; $ftm=$_POST['ID'.$x.'ftm']; $tpa=$_POST['ID'.$x.'tpa']; $tpm=$_POST['ID'.$x.'tpm']; $fta=$_POST['ID'.$x.'fta']; $ftm=$_POST['ID'.$x.'ftm']; $stl=$_POST['ID'.$x.'stl']; $trb=$_POST['ID'.$x.'trb']; $ast=$_POST['ID'.$x.'ast']; $blka=$_POST['ID'.$x.'blka']; $blkf=$_POST['ID'.$x.'blkf']; $tovr=$_POST['ID'.$x.'tovr']; mysql_query("INSERT INTO stats (gameId, fga, fgm, tpa, tpm, fta, ftm, ast, stl, trb, blka, blkf, tovr) VALUES ('$gameId', '$fga', '$fgm', '$tpa', '$tpm', '$fta', '$ftm', '$ast', '$stl', '$trb', '$blka', '$blkf', '$tovr')")or die("<div class='errmsg'>Insert Error: ".mysql_error()."</div><br /> \n"); $x++; Can anyone see what ive done wrong? Thanks Hi, When I use the below table in a while loop, it will repeat down the page. I want it to repeat in rows of 3, how can I do this? Code: [Select] while () { echo ' <table width="50%" cellpadding="2" cellspacing="1" bgcolor="'.$border.'"> <tr > <td colspan="5" height="20" align="center" class="title" bgcolor="'.$bghead.'"><b>'.$pt['platform'].'</b></td> </tr> </table>'; } Thanks! Using a for loop counting from 0 to 9, I need to make this into a table. Making sure the table is 100% of the page. Any sort of help is appreciated. Thank you 0 1 2 3 4 5 6 7 8 9 Hello everyone, Sorry if this has been answered but if it has I can't find it anywhere. So, from the begining then. Lets say I had a member table and in it I wanted to store what their top 3 interests are. Their$ row has all the usual things to identify them userID and password etc.. and I had a further 3 columns which were labled top3_1 top3_2 & top3_3 to put each of their interests in from a post form. If instead I wanted to store this data as a PHP Array instead (using 1 column instead of 3) is there a way to store it as readable data when you open the PHPmyadmin? At the moment all it says is array and when I call it back to the browser (say on a page where they could review and update their interests) it displays 'a' as top3_01 'r' as top3_02 and 'r' as top3_03 (in each putting what would be 'array' as it appears in the table if there were 5 results. Does anyone know what I mean? For example - If we had a form which collected the top 3 interests to put in a table called users, Code: [Select] <form action="back_to_same_page_for_processing.php" method="post" enctype="multipart/form-data"> <input name="top3_01" type="text" value="enter interest number 1 here" /> <input name="top3_02" type="text" value="enter interest number 2 here" /> <input name="top3_03" type="text" value="enter interest number 3 here" /> <input type="submit" name="update_button" value=" Save and Update! " /> </form> // If my quick code example for this form is not correct dont worry its not the point im getting at :) And they put 'bowling' in top3_01, 'running' in top3_02 and 'diving' in top3_03 and we catch that on the same page with some PHP at the top --> Code: [Select] if (isset($_POST)['update_button']) { $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars $top3_02 = $_POST['top3_02']; // i.e, 'running' $top3_03 = $_POST['top3_03']; // i.e, 'diving' With me so far? If I had a table which had 3 columns (1 for each interest) I could put something like - Code: [Select] include('connect_msql.php'); mysql_query("Select * FROM users WHERE id='$id' AND blah blah blah"); mysql_query("UPDATE users SET top3_01='$top3_01', top3_02='$top3_02', top3_03='$top3_03' WHERE id='$id'"); And hopefully if ive got it right, it will put them each in their own little column. Easy enough huh? But heres the thing, I want to put all these into an array to be stored in the 1 column (say called 'top3') and whats more have them clearly readable in PHPmyadmin and editable from there yet still be able to be called back an rendered on page when requested. Continuing the example then, assuming ive changed the table for the 'top3' column instead of individual colums, I could put something like this - Code: [Select] if (isset($_POST)['update_button']) { $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars $top3_02 = $_POST['top3_02']; // i.e, 'running' $top3_03 = $_POST['top3_03']; // i.e, 'diving' $top3_array = array($top3_01,$top3_02,$top3_03); include('connect_msql.php'); mysql_query("UPDATE members SET top3='$top3_array' WHERE id='$id' AND blah blah blah"); But it will appear in the column as 'Array' and when its called for using a query it will render the literal string. a r r in each field instead. Now I know you can use the 'serialize()' & 'unserialize()' funtcions but it makes the entry in the database practically unreadable. Is there a way to make it readable and editable without having to create a content management system? If so please let me know and I'll be your friend forever, lol, ok maybe not but I'd really appreciate the help anyways. The other thing is, If you can do this or something like it, how am I to add entries to that array to go back into the data base? I hope ive explained myself enough here, but if not say so and I'll have another go. Thanks very much people, L-PLate (P.s if I sort this out on my own ill post it all here) I have a script that displays a certain result set, the row I am concerned about is called 'endonum'. Some rows will have the same number in this field. Is there a way to only show 1 result with the same number in this field. The array will be like '1, 2, 3, 3, 4, 4, 4, 4, 5, 5, 5' and so on, but I just want to display 1 of them, not all. Kinda confusing but maybe someone gets it. Here is the code. <?php $selectendo = mysql_query("SELECT * FROM endorse WHERE agency = '$agency' AND finalized = 'No'")or die(mysql_error()); while($showendo = mysql_fetch_array($selectendo)) { $endonumber = $showendo['endonum']; ?> <li><a href="viewendo.php?endonum=<?php echo $endonumber;?>">Endorsement Number:<?php echo $endonumber . " Date: " . $showendo['date'];?></a></li> <?php } ?> Hi, Here is an extract of my while loop while ($personquery = mysql_fetch_array($personfetch, MYSQL_ASSOC)) { echo "$personfetch[first_name]"; } This will list each person now I want to do an INSERT to the database on every single member that is being listed I can only get it to INSERT for the one. Thanks mysql_query("update pupils set record='running' where pid !='$testing[0]' |
