I am trying to stop 2 tables from being updated based on an update on the first table.
Here is what I have to check the first table.
//add user to pif_table//
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query="UPDATE `pif_table` SET $g = '$uname', #success = 1 WHERE $g IS NULL OR $g = '' AND id = '$id' ";
$db->setQuery($query);
$result = $db->execute();
So, the first table, above is updated only if the $g column is empty.
I only wish the next 2 tables to be updated IF, $g column was empty and was updated above.
I receive a syntax error from the #success = 1 part of the command.
if ($success == 1){
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query="UPDATE `jospk_users` SET tables = tables +1, payments = payments +1, tbl".$pifbase."= tbl".$pifbase." +1 WHERE id = '$uid'";
$db->setQuery($query);
$result = $db->execute();
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query = "INSERT INTO `pif_payments` (`table_num`, `r_1`, `r_2`, `r_3`, `r_4`, $g, `amount`) VALUES ('$id', '$r1', '$r2', '$r3', '$r4', '$uname', '$pifbase') ON DUPLICATE KEY UPDATE $g = '$uname'";
$db->setQuery($query);
$result = $db->execute();
}
From what I understand, the Jommla's JFactory's execute method will not return false if the record was not updated and you can only check this if you query the database.
So, create a variable or array with the new value(s) before attempting to run the first UPDATE query and once you have, check the record and see if it matches the new value if so keep running the remaining queries.

I did 3 queries (SELECT, INSERT, UPDATE) it works but at the current state looks ugly and not safe.
Is there any way to make these SELECT, INSERT, UPDATE queries more readable and safer than this with the prepared statement?
$email = $_SESSION['email'];
$query = "SELECT username FROM users WHERE email='$email'";
$result = mysqli_query($connect, $query);
$row = mysqli_fetch_assoc($result);
$username = $row['username'];
if(!empty($_POST["comment"])){
$id = $_GET['id'];
$sql = "INSERT INTO user_comments (parent_id, comment, username, custom_id) VALUES ('".$_POST["commentID"]."', '".$_POST["comment"]."', '$username', '$id')";
mysqli_query($connect, $sql) or die("ERROR: ". mysqli_error($connect));
/// I need this update query to make every inserted comment's ID +1 or can I do this more simple?
$sql1 = "UPDATE user_comments SET id = id +1 WHERE custom_id = '$id'";
mysqli_query($connect, $sql1) or die("ERROR: ". mysqli_error($connect));
Give this a try. You can use $ex->insert_id to get the last entered ID. This may come in handy when mass inserting into a DB. I generally use PDO as I find the code looks cleaner but it's all preference I suppose. Keep in mind for the ->bind_param line that "isii" is referring to the type(s) of data which you are entering. So, in this case, its Integer, String, Integer, Integer (I may have got this wrong).
$email = $_SESSION['email'];
$query = "SELECT username FROM users WHERE email='$email'";
$result = mysqli_query($connect, $query);
$row = mysqli_fetch_assoc($result);
$username = $row['username'];
if(!empty($_POST["comment"])){
$id = $_GET['id'];
$commentID = $_POST["commentID"];
$comment = $_POST["comment"];
$sql = "INSERT INTO user_comments (parent_id, comment, username, custom_id) VALUES (?, ?, ?, ?)";
$ex = $connect->prepare($sql);
$ex->bind_param("isii", $commentID, $comment, $username, $id);
if($ex->execute()){
// query success
// I need this update query to make every inserted comment's ID +1 or can I do this more simple?
$lastInsertID = $ex->insert_id;
$sql1 = "UPDATE user_comments SET id = id + 1 WHERE custom_id = ?";
$ex1 = $connect->prepare($sql1);
$ex1->bind_param("i",$lastInsertID);
if($ex1->execute()){
// query success
}else{
// query failed
error_log($connect->error);
}
}else{
//query failed
error_log($connect->error);
}
The portion that is trying to delete duplicate entries in the database seems incorrect. So I suppose I am asking what would be the correct way to do that in this example. I am not totally new to PHP , but this is beyond me. If you could please tell me what is wrong and how to fix that would be greatly appreciated.
Now on to what I am trying to accomplish. I have a multidimensional array filled with values that is generated by a function. What I am trying to do is if there is a value in the array that already exists in the database delete it. Code:
enter code here
if(is_array($items)){
$values = array();
foreach($items as $row => $value){
$rsn = mysqli_real_escape_string($connect, $value[0]);
$rank = mysqli_real_escape_string($connect, $value[1]);
$values[] = "('', '$rsn', '$rank', '')";
$sql = "SELECT id FROM users WHERE rsn = :rsn";
$query = $conn->prepare($sql);
$query->execute(array(":rsn" => $value[0]));
$results = $query->rowCount();
while($deleted = $query->fetch(PDO::FETCH_ASSOC)){
$sql = "DELETE FROM users WHERE id = :id";
$query = $conn->prepare($sql);
foreach($deleted as $delete){
$query->execute(array(':id' => $delete));
}
}
}
//user_exists_delete($conn, $rsn);
$sql = "INSERT INTO users(id, rsn, rank, points) VALUES ";
$sql .= implode(', ', $values);
if(!empty($rank)&& !empty($rsn)){
if(mysqli_query($connect, $sql)){
echo "success";
}else{
die(mysqli_error($connect));
}
}
}
EDIT: I have got it partially working now, just need it to delete all dupes instead of only one. I edited code to reflect changes.
There are a couple problems, if you didn't strip much of your original code and if you don't need to do more than just what you shown why not just send a delete instruction to your database instead of checking validity first?
You have
//Retrieve ID according to rsn.
$sql = "SELECT id FROM users WHERE rsn = :rsn ";
//Then retrieve rsn using rsn??? Useless
$sql = "SELECT rsn FROM users WHERE rsn = :rsn ";
//Then delete using ID, retrieved by rsn.
$sql = "DELETE FROM users WHERE id = :id";
All those could simply be done with a delete using rsn...
$sql = "DELETE FROM users WHERE rsn = :rsn";
The row won't be deleted if there are no rows to delete, you don't need to check in advance. If you need to do stuff after, then you might need to fetch information before, but if not, you can use that while still checking the affected rows to see if something got deleted.
Now, we could even simplify the script by using only one query instead of one per user... We could get all rsn in an array and then pass it to the DELETE.
$sql = "DELETE FROM users WHERE rsn in :rsn";
//Sorry not exactly sure how to do that in PDO, been a while.
I fixed it I just omitted the WHERE clause in the delete statement so all records are being deleted before that insert gets ran again.
I need to fetch the id of the last inserted row from a mysql table using php and use that id to enter a new entry on another table. I have this until now
$inductionmethod = $_POST['inductionmethod'];
$injectionmethod = $_POST['injectionmethod'];
$dosage = $_POST['dosage'];
$metric = $_POST['metric'];
$notes = $_POST['notes'];
global $db_usr;
$query = "SELECT MAX( experiment_id ) FROM experiment";
$prep = $db_usr->prepare($query);
$lastid = $prep->fetch();
$query ="INSERT INTO experiment_using_methods (experiment_id, induction_method, injection_method, dosage_quantity, dosage_unit, dosage_qualitative)
VALUES (
'".$lastid['MAX( experiment_id )']."', # the fetched ID of the corresponding dataset
(SELECT induction_method_id FROM induction_method WHERE im_name = '".$inductionmethod."'), # name of induction method
(SELECT injection_method_id FROM injection_method WHERE im_name = '".$injectionmethod."'), # name of the injection method
'".floatval($dosage)."', # dosage quantity
'".$metric."', # dosage unit or metric
'".$notes."' # qualitative dosage - REMOVE??
)";
$prep = $db_usr->prepare($query);
$prep->execute();
I think I'm getting an error while fetching the MAX( experiment_id) or maybe I'm using it incorrectly on the INSERT statement because if I replace the ".$lastid['MAX( experiment_id )']." part by a number the insert statement works fine. On the other hand I also test the SELECT MAX( experiment_id ) FROM experiment statement on the mysql command line and it also works fine. Am I using fetch and referencing the result value correctly?
Thing this is the main issue:
$prep = $db_usr->prepare($query);
$lastid = $prep->fetch();
change it to:
$prep = $db_usr->prepare($query);
$prep->execute();
$lastid = $prep->fetch();
If you have connection as $con, then for MySQLi Object-oriented:
if ($con->query($sql) === TRUE) {
$last_id = $conn->insert_id;
}
MySQLi Procedural way:
if (mysqli_query($con, $sql)) {
$last_id = mysqli_insert_id($con);
}
PDO way:
$con->exec($sql);
$last_id = $con->lastInsertId();
please help me out and sorry for my bad English,
I have fetch data , on basis of that data I want to update the rows,
Follows my code
I fetched data to connect API parameters
<?php
$stmt = $db->stmt_init();
/* publish store for icube*/
$stmt->prepare( "SELECT id,offer_id,name,net_provider,date,visible,apikey,networkid FROM " ."affilate_offer_findall_icube WHERE visible='1' ");
$stmt->execute();
mysqli_stmt_execute($stmt); // <--------- currently missing!!!
mysqli_stmt_store_result($stmt);
$rows = mysqli_stmt_num_rows($stmt);
$stmt->bind_result( $id, $offer_id, $name, $net_provider, $date, $visible,$apikey,$networkid);
$sql = array();
if($rows>0)
{
while($info = $stmt->fetch() ) {
$jsondataicube = file_get_contents('filename/json?NetworkId='.$networkid.'&Target=Affiliate_Offer&Method=getThumbnail&api_key='.$apikey.'&ids%5B%5D='.$offer_id.'');
$dataicube = json_decode($jsondataicube, true);
foreach($dataicube['response']['data'][0]['Thumbnail'] as $key=>$val)
{
$offer_id = $dataicube['response']['data'][0]['Thumbnail']["$key"]['offer_id'];
$display = $dataicube['response']['data'][0]['Thumbnail']["$key"]['display'];
$filename = $dataicube['response']['data'][0]['Thumbnail']["$key"]['filename'];
$url = $dataicube['response']['data'][0]['Thumbnail']["$key"]['url'];
$thumbnail = $dataicube['response']['data'][0]['Thumbnail']["$key"]['thumbnail'];
$_filename = mysqli_real_escape_string($db,$filename);

$_thumbnail = mysqli_real_escape_string($db,$thumbnail);
$sql[] = '("'.$offer_id.'","icube","'.$_thumbnail.'","'.$_url.'")';
}
}
As I store values which have to be inserted in 'sql'
now
$stmt->prepare( "SELECT offer_id FROM " ."affilate_offer_getthumbnail_icube ORDER BY 'offer_id' ASC");
$stmt->execute();
mysqli_stmt_execute($stmt); // <--------- currently missing!!!
mysqli_stmt_store_result($stmt);
$rows = mysqli_stmt_num_rows($stmt);
$stmt->bind_result($offer_id);
$sqlimplode = implode(',', $sql);
if($rows>0)
{
$query = "UPDATE affilate_offer_getthumbnail_icube WHERE offer_id='".$offer_id."' SET '".$sqlimplode."'";
$stmt->prepare( $query);
$execute = $stmt->execute();
}
else
{
$query= "INSERT INTO affilate_offer_getthumbnail_icube(offer_id, net_provider,logo2020,logo100) VALUES".$sqlimplode;
$stmt->prepare( $query);

Insert query working well,but how can I update all the data like insert query ?
My Answer is refering to a "set and forget"-strategy. I dont want to look for an existing row first - probably using PHP. I just want to create the right SQL-Command and send it.
There are several ways to update data which already had been entered (or are missing). First you should alter your table to set a problem-specific UNIQUE-Key. This is setting up a little more intelligence for your table to check on already inserted data by its own. The following change would mean there can be no second row with the same value twice in this UNIQUE-set column.
If that would occur, you would get some error or special behaviour.
Instead of using PHPMyAdmin you can use this command to set a column unique:
ALTER TABLE `TestTable` ADD UNIQUE(`tablecolumn`);
After setting up your table with this additional intelligence, you alter your Insert-Command a little bit:
Instead of Insert you can drop and overwrite your Datarow with
REPLACE:
$query= "REPLACE INTO affilate_offer_getthumbnail_icube
(offer_id, net_provider,logo2020,logo100) VALUES (".$sqlimplode.")";
See: Replace Into Query Syntax
Secondly you can do this with the "On Duplicate Key"-Commando.
https://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html
$query= "INSERT INTO affilate_offer_getthumbnail_icube
(offer_id, net_provider,logo2020,logo100)
VALUES (".$sqlimplode.")
ON DUPLICATE KEY UPDATE net_provider = ".$newnetprovider.",
logo2020 = ".$newlogo2020.",
logo100 = ".$newlogo100.";";
Note: I think you missed some ( and ) around your $sqlimplode. I always put them around your implode. Maybe you are missing ' ' around strings as well.
Syntax of UPDATE query is
UPDATE table SET field1 = value1, field2 = value2 ...
So, you cannot pass your imploded array $sql to UPDATE query. You have to generate another sql-string for UPDATE query.
This is clearly incorrect:
$query = "UPDATE affilate_offer_getthumbnail_icube
WHERE offer_id='".$offer_id."' SET '".$sqlimplode."'";
If the intention is to INSERT offer_id='".$offer_id."' and then UPDATE ... SET offer_id = '".$sqlimplode."'";
You have to use two separate queries, one for INSERT and then another one for UPDATE
An Example:
$query = "INSERT INTO affilate_offer_getthumbnail_icube
(col_name) VALUES('".$col_Value."')";
//(execute it first);
$query2 = "UPDATE affilate_offer_getthumbnail_icube SET
col_name= '".$col_Value."'" WHERE if_any_col = 'if_any_Value';
//(execute this next);
Try this:
$sqlimplode = implode(',', $sql);
if($rows>0)
{
/*$fields_values = explode(',',trim(array_shift($sql), "()"));
$combined_arr = array_combine(['offer_id','net_provider','logo2020','logo100'],$fields_values);
$sqlimplode = implode(', ', array_map(function ($v, $k) { return $k . '=' . $v; }, $combined_arr, array_keys($combined_arr))); */
$query = "INSERT INTO affilate_offer_getthumbnail_icube(offer_id, net_provider,logo2020,logo100) VALUES".$sqlimplode." ON duplicate key update net_provider = values(net_provider),logo2020 = values(logo2020),logo100 = values(logo100)";
$stmt->prepare( $query);
$execute = $stmt->execute();
}
else
{
$sqlimplode = implode(',', $sql);
$query= "INSERT INTO affilate_offer_getthumbnail_icube(offer_id, net_provider,logo2020,logo100) VALUES".$sqlimplode;
$stmt->prepare( $query);
$execute = $stmt->execute();
}
I'm having a problem with inserting info into the database. Strangely the update query works but not the insert query. I don't get any error either when submitting, it goes through correctly and echo account saved but nothing is inserted. What am i missing or doing wrong. please assist
if(isset($_POST['Submitaccount'])){
$allowedusers = $_POST['users'];
$accountid = trim($_POST['accountid']);
if(!$_POST['copyperms']) $_POST['copyperms']='N';
if(!$_POST['allusers']) $_POST['allusers']='N';
if(!$_POST['enabled']) $_POST['enabled']='N';
if(!$_POST['servertime']) $_POST['servertime']='N';
if(!$_POST['delremovals']) $_POST['delremovals']='N';
unset($_POST['Submitaccount']);
unset($_POST['accountid']);
unset($_POST['users']);
$notmust = array("email" , "skip" , "comments" , "firstmod");
foreach($_POST as $key=>$val){
if(!trim($val) && !in_array($key , $notmust)) {
$err = 1;
$empty = "$key";
break;
}
$qpart .= "`$key` = '".mysql_escape_string($val)."' , " ;
}
if($qpart) $qpart = substr($qpart , 0 , -2);
if(!$err){
$chk = mysql_num_rows(mysql_query("SELECT * from accounts WHERE name = '".mysql_escape_string($_POST['name'])."' and id <> '$accountid'"));
if($chk >0){
$err = 2;
}
}
if(!$err){
if(!$accountid){
$q = "INSERT into accounts SET $qpart ";
mysql_query($q) or die("Error inserting the record :".mysql_error()."<br>".$q);
$accountid = mysql_insert_id();
}else{
$q = "UPDATE accounts SET $qpart WHERE id = '$accountid'";
mysql_query($q) or die("Error updating the record :".mysql_error()."<br>".$q);
}
}
This is because the INSERT command has different syntax:
INSERT into accounts SET $qpart "
is not usual, you can write it like this:
INSERT into accounts (column names) VALUES your values"
13.2.5 INSERT Syntax
You have double if(!$err){. Do you want both (!$err) into one? If the first (!$err) is for indicator for the second to insert, function SELECT can not be placed above the function INSERT indirectly.
try this:
if(!$err){
$chk = mysql_num_rows(mysql_query("SELECT * from accounts WHERE name = '".mysql_escape_string($_POST['name'])."' and id <> '$accountid'"));
if($chk >0){
$err = 2;
// if(!$err){ again ...
if(!$accountid){
$q = "INSERT into accounts SET (column1) VALUES ($var1)";
mysql_query($q) or die("Error inserting the record :".mysql_error()."<br>".$q);
$accountid = mysql_insert_id();
}
else{
$q = "UPDATE accounts SET $qpart WHERE id = '$accountid'";
mysql_query($q) or die("Error updating the record :".mysql_error()."<br>".$q);
}
}
}
else{
//other code to handle if ($err)
}
Note: I would prefer using PDO to handle database, it's so simple scripting, besides, it's no longer supported
You have to understand that mysql functions have become deprecated. Either using mysqli or pdo would be the better option, but if you absolutely have to use mysql as a solution i would suggest not posting the form to itself, rather post to another php file as you will have less problems.In my environment it seems to work well as an interim solution while we are rewriting everything to use mysqli.If it a go and let me know.
