PHP - Mysql Unique Key Error
I have a mysql unique index on two columns:
UNIQUE KEY `page_id` (`page_id`,`tag_id`) I have a mysql query like this: Code: [Select] mysql_query("insert into link_tags (page_id, tag_id) values ($page_id, $tag_id)"); If I run that, what would be the best way for php not to fail if the key already exists? within a while loop, would this be best? Code: [Select] if(mysql_query("insert into link_tags (page_id, tag_id) values ($page_id, $tag_id)")) continue; Or would the code above (first code) be sufficient enough? Similar TutorialsI have a mysql table which will store users email addresses (each is unique and is the primary field) and a timestamp. I have added another column called `'unique_code' (varchar(64), utf8_unicode_ci)`. What I would very much appreciate assistance with is; a) Generating a 5 digit alphanumeric code, ie: 5ABH6 b) Check all rows the 'unique_code' column to ensure it is unique, otherwise re-generate and check again c) Insert the uniquely generated 5 digit alphanumeric code into `'unique_code'` column, corresponding to the email address just entered. d) display the code on screen. What code must I put and where? **My current php is as follows:** Code: [Select] require "includes/connect.php"; $msg = ''; if($_POST['email']){ // Requested with AJAX: $ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'); try{ if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){ throw new Exception('Invalid Email!'); } $mysqli->query("INSERT INTO coming_soon_emails SET email='".$mysqli->real_escape_string($_POST['email'])."'"); if($mysqli->affected_rows != 1){ throw new Exception('You are already on the notification list.'); } if($ajax){ die('{"status":1}'); } $msg = "Thank you!"; } catch (Exception $e){ if($ajax){ die(json_encode(array('error'=>$e->getMessage()))); } $msg = $e->getMessage(); } } Hi, First off: I got a table with two columns and 100.000 rows. Some of the rows are duplicates (allowing me to "weight" the chance of some rows being hit the first time the script runs) Allright. This i what I want to do: When the user clicks a button: 1. Generate a random selected row from the table (this I allready accomplished using this code: Code: [Select] <?php //CODE FROM WWW.GREGGDEV.COM function random_row($table, $column) { $max_sql = "SELECT max(" . $column . ") AS max_id FROM " . $table; $max_row = mysql_fetch_array(mysql_query($max_sql)); $random_number = mt_rand(1, $max_row['max_id']); $random_sql = "SELECT * FROM " . $table . " WHERE " . $column . " >= " . $random_number . " ORDER BY " . $column . " ASC LIMIT 1"; $random_row = mysql_fetch_row(mysql_query($random_sql)); if (!is_array($random_row)) { $random_sql = "SELECT * FROM " . $table . " WHERE " . $column . " < " . $random_number . " ORDER BY " . $column . " DESC LIMIT 1"; $random_row = mysql_fetch_row(mysql_query($random_sql)); } return $random_row; } //USAGE $randomdata = random_row('MYTABLE', 'MYCOLUMN'); echo $randomdata[2]; // Where [2] is the data I want to extract. ?> This script works fine. The problem is that I want to exclude the results that have allready been shown. With me? Therefore, since I have duplicate rows of certain data, I need to exclude all the rows that are the same. I have a couple of solutions, but I can't seem to fit it into this script. (I will not use the ORDER_BY_RAND() query; it'll be too slow for a table with 100.000 rows) SO: Here's ideas I've come up with that might work, but because of my limited experience with PHP and MySQL, haven't been able to accomplish. 1) Insert a "temporary" column in the table which is filled with 1 and 0's where 1 indicates that the row has allready been taken? (If possible) 2) Use PHP sessions to store the previously generated rows? 3) Create a temporary table, which fills up with the allready generated rows by the random script? 4) Create a unique txt-file (e.g: _USERSIPADRESS__.txt) which can be used to save and extract data from the random script? (fopen, fwrite and so fourth) I hope you understand what I'm trying to do Any suggestions would be highly appreciated. Thank you. Hello guys, How do I total unique id's with php or MySQL. For instance in MySQL I have... ID 1 1 3 4 2 1 1 3 How can I total all of the 1's, all of the twos, all of the threes and so forth. I have four 1's, one 2, two 3's and so forth... I am trying to write a script that runs through a CSV file and inserts unique values in a mysql database and spits the duplicate out into a new CSV. I can find the duplicates when I load it into an array, but when I insert them into a MySQL database, I cannot determine if they are duplicates. If I use INSERT IGNORE, it will run the whole file, and reject the duplicates. This is fine, except I need to create a file of the duplicate entries. What is the best way to determine if the insert attempt was rejected? I could do a select to see if the row is there, spit it out...insert if not, but I was thinking there should be a way for MySQL to talk back to me to cut the queries in half... Any ideas? Thanks Solution: Turns out the headers will not send unless all of the other code is behind an else userinfo.php?user=MikeH, possible addition to the sticked post? So strictly speaking I dont have a header error because my script does not produce errors. However my script should be redirecting me to "notes.php?error=ad" but instead it just sends me back to the page I was previously at. My script is made to process a download via "tokens" and then redirect the user. That all works fine but what I am trying to do now is check if the user has already about the download and if they have redirect them to the error page letting them know. So in short the URL goes like this: notes.php?viewn=2 -> purchase.php?user=MikeH&nid=2 (unseen page all processing) -> notes.php?error=ad however what it is doing is: notes.php?viewn=2 -> purchase.php?user=MikeH&nid=2 (unseen page all processing) -> notes.php?viewn=2 Here is the notes code: <?php }else if (isset($_GET['viewn'])){ $cid = $_GET['viewn']; $query = "SELECT * FROM approvednotes WHERE cid =".$cid; $res = mysql_query($query) or die (mysql_error()); $i=0; $r=1; ?> <h2>Programs:</h2> <table summary="Summary Here" cellpadding="0" cellspacing="0"> <tr> <td><b>File Name</b></td> <td><b>Author</b></td> <td><b>Cost</b></td> <td><b>Buy</b></td> </tr> <?php echo "<tbody>"; echo "<tr class= \"dark\">"; while ($row = mysql_fetch_array($res)){ if($i == 1){ echo "</tr>"; $r++; if($r% 1 == 0){ echo "<tr class = \"light\">"; $i=0; $r = 0; }else{ echo "<tr class = \"dark\">"; $i=0; } } echo "<td> ". $row['name']."</td><td>".$row['username']."</td><td>".$row['value']." <img src=\"images/money.png \" height=\"30px\" /></td><td><a href=\"purchase.php?user=".$session->username."&nid=".$row['id']."\"><img src=\"images/buy.png\" height=\"30px\"/></a></td>"; $i++; } echo "</table>"; }?> Here is the purchase code: <?php include("include/session.php"); if($session->checkLogin()){ $user= $_GET['user']; if ($user == $session->username){ $note = $_GET['nid']; $query3 = "SELECT * FROM users_downloaded WHERE nid=$note AND username='$user'"; $res3 = mysql_query($query3) or die (mysql_error()); $pass = mysql_num_rows($res3); if ($pass != 0){ header("Location: notess.php?error=ad"); } $nquery = "SELECT * FROM approvednotes WHERE id= ".$note; $nres = mysql_query($nquery) or die (mysql_error()); //Get info about the file while ($nrow = mysql_fetch_assoc($nres)){ $price = $nrow['value'] ; $location = $nrow['location']; } //see if user even has enough credits for this function creditcheck($username){ $usern= $_GET['user']; $query = "SELECT * FROM users WHERE username = '".$usern."'"; $res = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($res)){ $credits = $row['credits']; } return $credits; } $credits = creditcheck($user); if($credits >= $price){ //user has enough credits to purchase note. $newamount = $credits - $price; $person = $session->username; $query = "UPDATE users SET credits =".$newamount." WHERE username='$person'"; $res = mysql_query($query) or die (mysql_error()); $query2 = "INSERT INTO users_downloaded (nid, username) VALUES ('$note','$person')"; $res2 = mysql_query($query2) or die (mysql_error()); header("Location: download.php?f=".$location); exit; }else{ //error not enough money!! header("Location: notes.php?error=ne"); } } }else{ header ("Location: notes.php?error=nl"); } ?> I've started a to-do app, and everything works fine. Every user has his own unique to-do items that he can add. The only issue is that when I log-in with a user, ALL the items of all users are displayed when I'm redirect to my main page. I want to make it as so every user has his own page where only the to-do items he has created are visible, not every item from every user. I'm a total beginner with PHP so I'm sorry if this is a stupid question. This is my todomain.php code
<?php
require 'db_conn.php';
require 'config.php';
session_start();
// If the session variable is empty, this
// means the user is yet to login
// User will be sent to 'login.php' page
// to allow the user to login
if (!isset($_SESSION['id'])) {
$_SESSION['msg'] = "You have to log in first";
header('location: login.php');
}
// Logout button will destroy the session, and
// will unset the session variables
// User will be headed to 'login.php'
// after loggin out
if (isset($_GET['logout'])) {
session_destroy();
unset($_SESSION['id']);
header("location: login.php");
}
?>

I spent several hours trying to figure this thing out. Thought I had it nailed, but still getting duplicate record entries into the MySQL DB when I do NOT want them.
Here's the plot:
People filling out the possible attendance form for a Ham Radio event *sometimes* bring a 2nd person (either a spouse or a friend). The 2nd person may, or may not, also has a Callsign which I need to put INSERT the same MySQL Callsign column. In any event, to also identify the 2nd person as coming 'with' the 1st person.
MOST of the attendees are individuals with NO 2nd person.
My entry form has these primary fields:
callsign
fullname
AND...
callsign2
fullname2
What I came up with was to process the MySQL INSERT for the primary callsign & fullname into their respective MySQL DB Columns (which works fine), and then........... immediately following the main Query INSERT, to do a substitution type thing depending on whether or not a form entry was made in the callsign2 field, AND/OR, the fullname2 field.
This partially works, but if there is ONLY a primary callsign and fullname in the form, I'm still getting a duplicate record entry which includes the callsign in the `with` column (which should ONLY take place IF there is a 2nd person indicated).
Confusing?
Here is what I have been wrestling with to try and accomplish the objective, and now my eyes are glazed over ;-(
// TRICKY PART HERE
// If a 2nd Callsign AND a Fullname
if ($callsign2 != ' ' && $fullname2 != ' ') {
// Still make reference to the primary Callsign in the MySQL DB `with` column
$with = $callsign;
// Assignment to allow 2nd Callsign to be entered in the MySQL `callsign` column
$callsign=$callsign2;
$fullname=$fullname2;
$sql="INSERT INTO `mytable` (`callsign`, `fullname`, `with`)
VALUES ('$callsign', '$fullname', '$with')";
// If NO 2nd Callsign BUT a Fullname
} elseif ($callsign2 = ' ' && $fullname2 != ' ') {
// Make reference to the primary Callsign in the MySQL DB `with` column
$with = $callsign;
$callsign=$callsign2;
$fullname=$fullname2;
$sql="INSERT INTO `mytable` (`callsign`, `fullname`, `with`)
VALUES ('$callsign', '$fullname', '$with')";
} else {
// The only thing I could thing of to (hopefully) NOT make a 2nd entry
// record in the MySQL DB IF there is NO 2nd person referenced
$with = $callsign;
}
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
This mostly works EXCEPT if only a single (primary) person entry.
The recap the objetives:
1. If ONLY a primary/single person entry on the form:
* callsign & fullname get INSERTed into the `callsign` and `fullname` columns in the DB as ONLY one record entry
2. If BOTH a primary and 2nd person on the form:
A. IF the 2nd person has a Callsign, then the 2nd record entry would be:
* callsign2 & fullname2 get INSERTed into the `callsign` & `fullname` columns in the 2nd DB as a separate record entry
* callsign of the primary person also gets INSERTED into the `with` column in the same 2nd DB record entry
B. IF the 2nd person does NOT have a callsign, then the 2nd record entry would be:
* fullname2 gets INSERTed into the `fullname` column in the DB as a separate 2nd DB record entry
* callsign of the primary person also gets INSERTED into the `with` column in the same 2nd DB record entry
I obvioiusly have overlooked something, but just can't seem to figure it out at this point {SIGH}.
Thanks for any enlightenment.

I have a form that passes multiple images and I wanted them to have a substring of a md5 encrypted time for generating unique codes so I don't delete or overwrite an older file. I keep the actual images in a folder and the path in mysql. The folder is working perfectly and there are no problems generating unique codes but I have been trying all night and I can't figure out why mysql won't update. I can actually get it to update but then I loose the functionallity of the code and if I don't upload a 4 images and leave one blank, the blank one deletes the previously uploaded field in the table row. Here is the md5 encrypted time for generating unique codes: Code: [Select] $unique = strtolower(substr(md5(time()), 0, 4)); This is how it works with the folder: Code: [Select] $filePath = $uploadDir . $unique . $fileName; This is how I get it to update mysql but then loose functionality: Code: [Select] $values[$i] = $unique . mysql_real_escape_string(basename(trim($_FILES[$fields[$i]]['name']))); Here is the entire code: Code: [Select] <?php require_once('storescripts/connect.php'); mysql_select_db($database_phpimage,$phpimage); $unique = strtolower(substr(md5(time()), 0, 4)); $uploadDir = 'upload/'; if(isset($_POST['upload' . $config])) { foreach ($_FILES as $file) { $fileName = $file['name']; $tmpName = $file['tmp_name']; $fileSize = $file['size']; $fileType = $file['type']; if($fileName==""){ $filePath = 'upload/'; } else{ $filePath = $uploadDir . $unique . $fileName; } $filePath = str_replace(" ", "_", $filePath); $result = move_uploaded_file($tmpName, $filePath); if(!get_magic_quotes_gpc()) { $fileName = addslashes($fileName); $filePath = addslashes($filePath); } $fileinsert[]=$filePath; } } $mid = mysql_real_escape_string(trim($_POST['mid'])); $cat = mysql_real_escape_string(trim($_POST['cat'])); $item = mysql_real_escape_string(trim($_POST['item'])); $price = mysql_real_escape_string(trim($_POST['price'])); $about = mysql_real_escape_string(trim($_POST['about'])); $fields = array(); $values = array(); $updateVals = array(); for($i=1; $i<=4; $i++) { $fields[$i] = 'name'.$i; $values[$i] = mysql_real_escape_string(basename(trim($_FILES[$fields[$i]]['name']))); if($values[$i] != '') { $updateVals[] = "{$fields[$i]} = '{$values[$i]}'"; } } $updateNames = ''; if(count($updateVals)) { $updateNames = ", " . implode(', ', $updateVals); } $update = "INSERT INTO image (mid, cid, item, price, about, name1, name2, name3, name4) VALUES ('$mid', '$cat', '$item', '$price', '$about', '$values[1]', '$values[2]', '$values[3]', '$values[4]') ON DUPLICATE KEY UPDATE cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames"; $result = mysql_query($update) or die (mysql_error()); $id = mysql_insert_id(); ?> <p style="font-size:35px; font-family:Arial, Helvetica, sans-serif; color:#255E67; margin-left:25px;">Your Item Has Been Uploaded!</p> <script type="text/javascript"> setTimeout('ourRedirect()', 2000) function ourRedirect() { location.href='protator_php.php?mid=<?php echo $id ?>' } </script> Hello, I need some help.

I've tested the MySQL in PHPMyAdmin and it runs fine, which is why I've posted this in PHP problems. All I want to do is copy one table to another (dropping the other first) as a backup, then recreate the original table but blank. I've tried running the functions in PHPMyAdmin, which works. Then I used its "Create PHP Code" function to make the PHP, which I edited to remove line breaks etc. Even if I used the unedited PHP made by PHPMyAdmin, it still doesn't work! The error is always a syntax one: "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 'CREATE TABLE mobackup (campaign_id varchar(20) NOT NULL, number varchar(13) NOT ' at line 1" Here's the code: Code: [Select] <?php $connection = mysql_connect(connection details hidden for security purposes, but they definitely work); mysql_select_db("betfredpiri", $connection); $sql = "DROP TABLE IF EXISTS mobackup; CREATE TABLE mobackup (campaign_id varchar(20) NOT NULL, number varchar(13) NOT NULL, message varchar(160) NOT NULL, mo_id int(15) NOT NULL, shortcode int(7) NOT NULL, received_time varchar(20) NOT NULL, network varchar(15) NOT NULL, retry tinyint(1) NOT NULL, FULLTEXT KEY message (message)) ENGINE = MyISAM DEFAULT CHARSET = latin1; INSERT INTO mobackup SELECT * FROM mo; DROP TABLE IF EXISTS mo; CREATE TABLE mo (campaign_id varchar(20) NOT NULL, number varchar(13) NOT NULL, message varchar(160) NOT NULL, mo_id int(15) NOT NULL, shortcode int(7) NOT NULL, received_time varchar(20) NOT NULL, network varchar(15) NOT NULL, retry tinyint(1) NOT NULL, FULLTEXT KEY message (message)) ENGINE = MyISAM DEFAULT CHARSET = latin1;"; mysql_query(mysql_real_escape_string($sql)); ?> I've also tried it with the following statements: Code: [Select] <?php $sql2 = "DROP TABLE IF EXISTS mobackup;" ."CREATE TABLE mobackup (campaign_id varchar(20) NOT NULL, " ."number varchar(13) NOT NULL, " ."message varchar(160) NOT NULL, " ."mo_id int( 15 ) NOT NULL, " ."shortcode int(7) NOT NULL, " ."received_time varchar(20) NOT NULL, " ."network varchar(15) NOT NULL, " ."retry tinyint(1) NOT NULL, " ."FULLTEXT KEY message (message) ) ENGINE = MyISAM DEFAULT CHARSET = latin1;" ."INSERT INTO mobackup SELECT * FROM mo;" ."DROP TABLE IF EXISTS mo;" ."CREATE TABLE mo (campaign_id varchar(20) NOT NULL, " ."number varchar(13) NOT NULL, " ."message varchar(160) NOT NULL, " ."mo_id int(15) NOT NULL, " ."shortcode int(7) NOT NULL, " ."received_time varchar(20) NOT NULL, " ."network varchar(15) NOT NULL, " ."retry tinyint(1) NOT NULL, " ."FULLTEXT KEY message (message)) ENGINE = MyISAM DEFAULT CHARSET = latin1;"; ?>and Code: [Select] <?php $sql3 = "\n" .
