PHP - How To Get Data Check From Multiple Tables?
Hi,
I have multiple table Table -1 order_no name 1 raj table -2 order_no name 1 raj table 3 order_no name 1 raj table 4 order_no name 1 raj table 5 order_no name 1 raj I want a query to check if the id (one) is present in all tables or not, i create this. select order_no from prepress, press, postpress, qc, binding, dispatch where order_no=prepress.order_no AND order_no=press.order_no AND order_no=postpress.order_no AND order_no=qc.order_no AND order_no=binding.order_no AND order_no=dispatch.order_no but the ambiguous error for order_no. how to achieve this can anyone suggest me? thanks Similar TutorialsOk I have a fairly straight forward question. I am designing a baseball website and I am trying to add in a schedule, here is what I have: Data Bases 1) Teams DB - Each team has a unique team ID, location, logo, and owner 2) Schedule DB - Each game has a unique game ID, and the schedule is set up like this: AWAY = Team ID, HOME = Team ID.... So I assume I am using the JOIN command to pull the schedule from both databases, any idea how the SQL command would look? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=305902.0 This 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 am trying to export multiple csv files to download from 2 separate tables in my database. Some background: I have a web app that links to a phpmyadmin database. There are 2 tables in the database (entering and exiting). These tables hold the phone inventory information of employees currently entering or exiting the organization. The fields in my tables a location, firstname, lastname, username, extension, mac, type What I am trying to do is export the data in these 2 tables to CSV (which I have working now) but I need to have multiple CSVs for each. For example, for my exiting table, I need to have one CSV export all the fields in the table and I also need another CSV to export just the location and username field. I have a simple html form with a submit button which is currently working now: <form action="exportexiting.php" method="POST" style="width: 456px; height: 157px"> <div> <fieldset> <legend style="width: 102px; height: 25px"><strong>Entering CSV:</strong></legend> <input name="Export" type="submit" id="Export" value="Export"> </fieldset><br/> </div> </form> This links to my exportexiting.php file: <?php $host = 'localhost'; $user = 'root'; $pass = 'xxxx'; $db = 'PhoneInventory'; $table = 'exiting'; // Connect to the database $link = mysql_connect($host, $user, $pass); mysql_select_db($db); require 'exportcsv.inc.php'; exportMysqlToCsv($table); ?> Then to exportcsv.inc.php: <?php function exportMysqlToCsv($table,$filename = 'export.csv') { $csv_terminated = "\n"; $csv_separator = ","; $csv_enclosed = ''; $csv_escaped = "\\"; $sql_query = "select * from $table"; // Gets the data from the database $result = mysql_query($sql_query); $fields_cnt = mysql_num_fields($result); $schema_insert = ''; for ($i = 0; $i < $fields_cnt; $i++) { $l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, stripslashes(mysql_field_name($result, $i))) . $csv_enclosed; $schema_insert .= $l; $schema_insert .= $csv_separator; } // end for $out = trim(substr($schema_insert, 0, -1)); $out .= $csv_terminated; // Format the data while ($row = mysql_fetch_array($result)) { $schema_insert = ''; for ($j = 0; $j < $fields_cnt; $j++) { if ($row[$j] == '0' || $row[$j] != '') { if ($csv_enclosed == '') { $schema_insert .= $row[$j]; } else { $schema_insert .= $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $row[$j]) . $csv_enclosed; } } else { $schema_insert .= ''; } if ($j < $fields_cnt - 1) { $schema_insert .= $csv_separator; } } // end for $out .= $schema_insert; $out .= $csv_terminated; } // end while header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Length: " . strlen($out)); // Output to browser with appropriate mime type, you choose header("Content-type: text/x-csv"); //header("Content-type: text/csv"); //header("Content-type: application/csv"); header("Content-Disposition: attachment; filename=$filename"); echo $out; exit; } ?> Again, this is working perfectly for only exporting all the data from the exiting table into one CSV file. My question is, how can I make my one submit button export the 2 CSV files that I need? Thanks for the help... I have a search where I want to be able to search a string of words. The search is going to be looking in 2 different table joined by a left outer join. The tables are "quotes" and "categories". $sql="SELECT q.id, q.username, q.quote, q.by, q.voteup, q.votedown, q.servtime, c.quote_id, c.label FROM quotes q LEFT OUTER JOIN categories c ON q.id = c.quote_id WHERE ( q.username LIKE '$srch' OR q.quote LIKE '$srch' OR q.`by` LIKE '$srch' OR c.label LIKE '$srch')"; The above mysql statement works and returns values..BUT if say, I search "john" and "funny", and a quote is posted by the user "john", but has a category of "funny" it will output the same quote twice. I was wondering if there was a way to see if a quote has either 1 term or both terms, if so display that quote but only display it once. Below is what the query is outputting. [100] => Array ( [id] => 100 [username] => John [quote] => new test quote blah blah [by] => John [voteup] => 0 [votedown] => 0 [servtime] => 2010-12-02 @ 16:27:03 [label] => Array ( [0] => Historic [1] => Serious [2] => Funny ) ) Here is the code in full. //// $sword = explode(" ",$search); foreach($sword as $sterm){ $srch="%".$sterm."%"; echo"$srch<br />"; $sql="SELECT q.id, q.username, q.quote, q.by, q.voteup, q.votedown, q.servtime, c.quote_id, c.label FROM quotes q LEFT OUTER JOIN categories c ON q.id = c.quote_id WHERE ( q.username LIKE '$srch' OR q.quote LIKE '$srch' OR q.`by` LIKE '$srch' OR c.label LIKE '$srch')"; $result=mysql_query($sql); while($row=mysql_fetch_object($result)){ $quote[$row->id]['id'] = $row->id; $quote[$row->id]['username'] = $row->username; $quote[$row->id]['quote'] = $row->quote; $quote[$row->id]['by'] = $row->by; $quote[$row->id]['voteup'] = $row->voteup; $quote[$row->id]['votedown'] = $row->votedown; $quote[$row->id]['servtime'] = $row->servtime; $quote[$row->id]['label'][] = $row->label; } echo"<pre>"; print_r($quote); echo"</pre>"; I don't think this is the fastest way of doing this, as it loops for each item in the db, per each keyword that is search.

I seem to be having difficulty inserting data into my database from checkbox items. My database has a column for each each fruit. I would like for each column to be populated with either a one(1) for checked or a zero(0) for not checked. Currently, my attempts have failed. I can either get all checkboxes to insert all zeros or I can get the first column to insert a one(1) while the others as zeros. Is there anybody here that can help me figure out what I am doing wrong and help me to re-work my code so I can get this to work? If anybody can help me using OOP methods that would be fantastic. Thank you all in advance.

Edited September 23, 2020 by ke-jo Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought. Basically what I have is a link table linking together source_id and subject_id. For each subject there are multiple sources associated with each. I had created a basic listing of sources by subject... no problem. I now need a way of having a form to create an ordered list in a user-specified way. In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display. I added another row to this table called order_by. No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting. I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script) Code: [Select] while($row = mysqli_fetch_array($rs)) { //update row order if (isset($_POST['submit'])) { //get variables, and assign order $subject_id = $_GET['subject_id']; $order_by = $_POST['order_by']; $source_id = $row['source_id']; //echo 'Order by entered as ' . $order_by . '<br />'; foreach ($_POST['order_by'] as $order_by) { $qorder = "UPDATE source_subject set order_by = '$order_by' WHERE source_id = '$source_id' AND subject_id = '$subject_id'"; mysqli_query($dbc, $qorder) or die ('could not insert order'); // echo $subject_id . ', ' . $order_by . ', ' . $source_id; // echo '<br />'; } } else { $subject_id = $_GET['subject_id']; $order_by = $row['order_by']; $source_id = $row['source_id']; } And have the line in the form like so: Code: [Select] echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/> (yes I know I didn't escape the input field... it's all stored in an htaccess protected directory; I will clean it up later once I get it to work) This, of course, results in every source_id getting the same "order_by" no matter what I put into each field. I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose; I don't have anyone to go to on this). I'm hoping someone here can help? Thanks a ton in advance Hey Folks! So, my brain is hurting now... I am making a little process to go through a table and if a row as one set of data, and the next row as the same data based on 3 fields then update a field in the current row. Here is a snippet of what I have been working on: <?php date_default_timezone_set('AUSTRALIA/BRISBANE'); $lasthour = (time() - 3600); $lastattack45 = (time() - 2820); $lasthalfhour = (time() - 1800); $lastfifteen = (time() - 900); $lastfhourhalf = (time() - 5400); $next15 = (time() + 900); $now = time(); mysql_connect($mysql_host, $mysql_user, $mysql_password) or die('Error connecting to mysql'); mysql_select_db($mysql_database); $result = mysql_query("SELECT feeder, attacker, defender, attacklandunix, smurfid, smurf, unixtime, record, leader FROM nation_incoming WHERE attacklandunix > $now && smurf <> 'smurfed' ") or die("SELECT Error: ".mysql_error()); while($row = mysql_fetch_array($result)){ $a[][feeder] = $row['feeder']; $a[][defender]= $row['defender']; $a[][landing]= $row['attacklandunix']; } foreach($a as $b){ //in here it is to compare the 'feeder' && 'defender' && 'attacklandunix' to the next row. IF the same combo exists, then update field 'leader' to "0". else update 'leader' to "1" } ?> How can/should I pull up the next row? Hi, How can i check if a string is a multiple of 0.1 without anything being left over? like 1.6 = true, 1.46 = false I have a form with multiple options to fill out (its a admin form) i want to make sure only one of the of the options are set, so im checking if the variable is empty with if ($variable1 != NULL) { $new_variable = "yep, this option was filled out"; } so if the form sent anything from the form with the value 'variable1' it then sets a new variable ($new_variable) Problem is i have multiple fields so i need to make sure if it finds a a variable is not empty, then too check if the others have anything in them too. If it does find another (meaning more than one has been filled out) echo an error (echo "you must only complete one option..") What is the best way to check if more than one variable exists? Sorry if i explained it complicated. Thank you Is it possible to have multiple check boxes on a single form and a single submit button tp post the values into different rows of DB Kenny Hello need some help keep getting Code: [Select] [function.readfile]: failed to open stream: No such file or directory in code im use Code: [Select] // Ziper function zipFilesAndDownload($file_names,$archive_file_name,$file_path){ $zip = new ZipArchive(); //create the file and throw the error if unsuccessful if ($zip->open($archive_file_name, ZIPARCHIVE::CREATE )!==TRUE) { exit("cannot open <$archive_file_name>\n"); } //add each files of $file_name array to archive foreach($file_names as $files) { $zip->addFile($file_path.$files,$files); } $zip->close(); $zipped_size = filesize($archive_file_name); header("Content-Description: File Transfer"); header("Content-type: application/zip"); header("Content-Type: application/force-download");// some browsers need this header("Content-Disposition: attachment; filename=$archive_file_name"); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header("Content-Length:".

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes.. something along the lines of if ($currentcatid =="31"||"32"||"1"||"24") { action } can anyone help? Thanks Hi Guys, Im using the code below to display the value of checked checkboxes on form submission, however im also trying to pull the price from the database for each checked value. foreach ($_POST['check'] as $product) { echo $row['price'] . " " . $row['currency'] . " for " . $product . "<br />"; } Please could somebody point me in the right direction as to what id need to do. As iv only been able to get it to display the price of the first checked value. Thanks Hey guys, Really dumb question, but I want to check if a bunch of variables are all not empty. Then, if they aren't, I want to execute a mySQL query. Right now I have this which I know is wrong because it doesn't work the right way: Code: [Select] if($album != null || $artist != null || $year != null || $genre != null) { // stuff here... } Obviously I want all of those variables to be checked if they are empty or not. I did a quick Google and found that checking if the variables are null wouldn't be the correct way of solving this situation because an "empty string" is still not null? Anyway, any help would be appreciated. I'm pretty sure it's really simple :p. Hi, I need help to check multiple rows for many columns, so that the script won't re-insert a duplicate entry. For eg: $isRowExist=mysql_query("SELECT (field1,field2) from table1 WHERE field1='$f1' AND field2='$f2' "); if(mysql_num_rows($isRowExist)==1) print "already in table1!"; else //proceed to insert into table table1 *BUT I tried this and it says mysql_num_rows expects resource, and this warning only shows when I have multipel columns I want to compare (it works just fine with one column in the WHERE clause above) Please help! I'm making a checklist. One table holds the list with IDs. There are about 224 rows, each with its own ideas. Now I have another table to hold user accounts. When you create an account, it shows you a fresh new checklist that you need to start checking off. Could anyone please share techniques so I can have multiple accounts have their own list they need to check off? (ie, when a new person creatures a new account they should have their own list with NOTHING checked) The only way I can think of doing this is making 224 fields for the user account with the IDs of the checklist table to check if I checked it or not. Surely there's an easier way? Thanks |
