The following query string is working from the phpMyAdmin SQL panel, but not from my php script.
I checked with mysqli_affected_rows()... it returns 0. But from SQL panel it affects particular 1 row.
The user account for the MySQL db I am using from php script has UPDATE privilege set.
UPDATE forecast SET forecastAmount = 1000.00, updBy='Admin User', updDt=now() WHERE companyId=2 AND forecastDate='2018-03-01';
PHP Script:
$forecastDate = date('Y-m-d', mktime(0, 0, 0, $_POST['forecastMonth'], ($i+1), $_POST['forecastYear']))."<br>";
$queryStringForecastUpdate = "UPDATE $tbl_forecast
SET forecastAmount = ".$_POST['day'][$i].
", updBy='".$_SESSION['ssnName'].
"', updDt=now()".
" WHERE companyId=".$_POST['forecastCompany'].
" AND forecastDate='$forecastDate';";
if (mysqli_query($dbConn, $queryStringForecastUpdate)) {
echo mysqli_affected_rows($dbConn);
$_SESSION['sccMsg'] = "Updated successfully";
} else {
$_SESSION['errMsg'] = "Error: " . $queryStringForecastUpdate . "<br>" . mysqli_error($dbConn);
}
Can anyone pls tell me what might goes wrong here?
got the problem: I mistakenly added a <br> at the end of $forecastDate assignment in line 1.

Once again I come back to all of you with another question.
I have tried everything in my mind as well as most of the recommendations I have found on the web and here in Stackoverflow but nothing seems to fix this issue for me.
For some reason the sql command in my code is returning false even though it should not.
Here is my php file called (dbRKS-DBTest.php)
<?php
//Gets server connection credentials stored in serConCred.php
//require_once('/../prctrc/servConCred2.php');
require_once('C:\wamp64.2\www\servConCred2.php');
//SQL code for connection w/ error control
$con = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
if(!$con){
die('Could not connect: ' . mysqli_connect_error());
}
//Selection of the databse w/ error control
$db_selected = mysqli_select_db($con, DB_NAME);
if(!$db_selected){
die('Can not use ' . DB_NAME . ': ' . mysqli_error($con));
}
//VARIABLES & CONSTANTS
//Principal Investigator Information
$PI_Selected = '6';
//Regulatory Knowledge and Support Core Requests variables
$RKS_REQ_1_Develop = '1';
//This sets a starting point in the rollback process in case of errors along the code
$success = true; //Flag to determine success of transaction
//start transaction
$command = "SET AUTOCOMMIT = 0";
$result = mysqli_query($con, $command);
$command = "BEGIN";
$result = mysqli_query($con, $command);
//Delete this portion of code afyer testing is finished
//Core Requests saved to database
$sql = "INSERT INTO rpgp_form_table_3 (idPI, RKS_REQ_1_Develop)
VALUES ('$PI_Selected', '$RKS_REQ_1_Develop')";
//*************TEsts code for "SCOPE_IDENTITY()" -> insert_id() for mysql
$sqlInsertId = mysqli_insert_id($con); //This value is supposed to be 0 since no queries have been executed.
echo "<br>MYSQLi_INSERT_ID() value before query should be 0 and it is:= " . $sqlInsertId;
//Checks for errors in the db connection.
$result = mysqli_query($con, $sql); //Executes query.
if($result == false){ //Checks to see for errors in previews query ($sql)
//die ('<br>Error in query to Main Form: Research Proposal Grant Preparation: ' . mysqli_error($con));
echo "<br>Result for the sql run returned FALSE. Check for error in sql code execution.";
echo "<br>Error given by php is: " . mysqli_error($con);
$success = false; //Chances success to false is it encounted an error in order to rollback transaction to database
}
else{
//*************TEsts code for "SCOPE_IDENTITY()" -> insert_id() for mysql
$sqlInsertId = mysqli_insert_id($con); //Saves the last id entered. This would be for the main table

$MAIN_ID = mysqli_insert_id($con); //Sets last entered id in the MAIN Form db to variable
}
//Checks for errors or craches inside the code
// If found, execute rollback
if($success){
$command = "COMMIT";
$result = mysqli_query($con, $command);
echo "<br>Tables have been saved witn 0 errors.";
}
else{
$command = "ROLLBACK";
$result = mysqli_query($con, $command);
echo "<br>Error! Databases could not be saved. <br>

}
$command = "SET AUTOCOMMIT = 1"; //return to autocommit
$result = mysqli_query($con, $command);
//Displays message
//echo '<br>Connection Successfully. ';
//echo '<br>Database have been saved';
//Close the sql connection to dababase
mysqli_close($con);
?>
Here is my php frontend html code named (RPGPHomeQueryTest.php)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<form id="testQuery" name="testQuery" method="post" action="../dbRKS-DBTest.php" enctype = "multipart/form-data">
<input type="submit" value="Submit query"/>
</form>
</html>
And here is how my database looks (rpgp_form_table_3):
So, when I open my html code, All I will see is a button since its all the code there is there. Once you press the button, the form should submit and execute the php code called (dbRKS-DBTest.php). This should take the predetermine values I already declared and saved them to the database called (rpgp_form_table_3). This database is set to InnoDB format.
Now, the output I should be getting is a message saying "Tables have been saved witn 0 errors." but the problem is that the message I am getting is this one bolow:
I honestly don't know why. I am posting this message to find guidance to this issue. I am still learning by myself and its been very did-heartedly to not find a solution this fixing this.
As always, I thank you for your patient and guidance! Let me know what other details I can provide.
Here is the SQL code you run:
$sql = "INSERT INTO rpgp_form_table_3 (idPI, RKS_REQ_1_Develop)
VALUES ('$PI_Selected', '$RKS_REQ_1_Develop')";
You are inserting data into rpgp_form_table_3. From the screenshot, we can see that table has several (7) fields yet you are only inserting 2 fields. The question then is: do you need to specify a value for all fields?
The error you are getting states
Error given by php is: Field 'idCollaRecord_1' doesn't have a default value Error! Databases could not be saved.
It's clear that you have to insert the row by specifying a value for each column, not just the two columns you are interested in.
Try
$sql = "INSERT INTO rpgp_form_table_3 (idPl, RKS_REQ_1_Develop, idCollaRecord_1, idCollaRecord_2, idCollaRecord_3, idCollaRecord_4)
VALUES ('$PI_Selected', '$RKS_REQ_1_Develop',0,0,0,0)";
Try this insert code. If the PI_Selected is NUMERIC use the First one. If it is string use the second one
$sql = "INSERT INTO rpgp_form_table_3 (idPI, RKS_REQ_1_Develop) VALUES (" .
$PI_Selected . ",'" . $RKS_REQ_1_Develop . "')";
$sql = "INSERT INTO rpgp_form_table_3 (idPI, RKS_REQ_1_Develop) VALUES ('" .
$PI_Selected . "','" . $RKS_REQ_1_Develop . "')";
I'm currently working on creating a login system, one part of which is of course registration. It's been going smoothly up until this point, where I'm getting an error.
I've researched this as thoroughly as I can, but I can't find the solution as it is giving me an incorrect line number.
The error I'm getting is:
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' at line 1
My SQL query is
$token = (round(microtime(true) * 1000));
$query = mysql_query("INSERT INTO "
. "`users` "
. "(name, password, email, token) "
. "VALUES "
. "('$_POST[user]'"
. ",'".hash('sha512',$_POST['pass'])."'"
. ",'$_POST[email]'"
. ",'$token')") or die(mysql_error());
if (mysql_query($query) === TRUE) {
//echo "Sucsessfuly registered! Check your email for a confirmation link.";
} else {
echo "Error: " . mysql_error();
}
(this is not the first line of the file, it's the 22d)
When the code runs, even though it throws the error it still is inserting the values into the table correctly.
Also when I run the same query in phpmyadmin, it runs just fine with no errors.
I've been trying to solve this error for the last 3 hours so any help would be appreciated ;)
You're calling mysql_query twice: first with the SQL, and then you're using the result of the query as if it were a query. The error you're getting is because $query is true, which gets turned into 1 when treated as a string.
Either you should just set $query to the SQL string:
$query = "INSERT INTO ...";
if (mysql_query($query)) {
...
} else {
...
}
or you should just check the value of $query:
$query = mysql_query(...);
if ($query) {
...
} else {
...
}
I have been reading about the Commands out of sync; you can't run this command now problem for some time now, and see that you cannot have any unread results left, which makes sense to me. However, in the following case, I don't see which results I am missing to free. I have left out the irrelevant things from my PHP and SQL code below.
# Set local variables
$sql = "
SET #STARTDATE = '2014-09-01';
SET #RANK = 0;
";
if (mysqli_multi_query($conn, $sql)) {
# Success: do nothing else
} else {
# Failure: output the error message
echo "Error: " . $sql . "<br>" . $conn->error;
}
# Fetch and store the results
$sql = "
SELECT * FROM MyTable
";
$result = mysqli_query($conn, $sql);
if (!$result) {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
The second query (the if (!$result) block) returns the infamous Commands out of sync error. If I comment out the first part, the second query runs no problem. If I change the first query into only one SET statement instead of two, the second query runs no problem. Therefore, it seems that I have to clear the 'success-flag' of every individual SQL statement from the first part. Is this correct? If so, how shall this be done?
EDIT: indeed it seems you have to flush all results in between. Adding the following line between part 1 and part 2 solves the problem.
while (mysqli_next_result($conn)) {;} // Flush multi_queries
I found this solution in a user comment on the PHP manual: http://nl3.php.net/manual/en/mysqli.multi-query.php
Quite simply, your first query
SET #STARTDATE = '2014-09-01';
SET #RANK = 0;
Will generate 2 result sets and until they have been processed, even though the result will be just a status you cannot continue.
So you need to do something like this :-
if (mysqli_multi_query($conn, $sql)) {
do {
/* unload result set */
if ($result = $mysqli->store_result()) {
// Check status
$result->free();
}
} while ($mysqli->next_result());
} else {
# Failure: output the error message
echo "Error: " . $sql . "<br>" . $conn->error;
}
Of course you should probably check for errors in that loop
if (!$mysqli->query("UPDATE custom_fav SET credits = credits + 1 WHERE user_id = $current")) {
echo "Credit addition failed: (" . $mysqli->errno . ") " . $mysqli->error;
} else {
echo 'hi';
}
Does anybody know why the mysqli query keeps running twice?
I am getting 1 of the echo statements but I am getting + 2 added to the database instead of 1.
For example i changed it to 5 and it added 10 into the database.
Most likely you are calling this script twice. It this script called via home-brewed SEO-friendly URL? Do not make it act as a 404 handler then.
So I have a website and I am trying to display the last update time of the mySQL server, I've looked around but still having problems. Here is my code
$sql = 'SHOW TABLE STATUS FROM alumni LIKE "alumni_data"';
$tableStatus = mysqli_query($link, $sql);
if (!$tableStatus) {
$error = 'Error getting update status: ' . mysqli_error($link);
include 'error.html.php';
exit();
}
while ($array = mysqli_fetch_array($tableStatus)) {
$updatetime = $array['Update_time'];
}
echo '<center>Last Updated: ' . $updatetime . '</center>';
What happens is nothing prints out, its like it never found the update time. I have manually typed that query so I am pretty sure it works.
Thanks
