For some reason the only row that is echoing is the user_id column, everything else is just blank. I tried a query with SELECT * and it still wasn't any different. Does anyone know what might be happening? I get the right results as it selects the one user in the table that meets the criteria. The problem is that the name and phone number are not echoing.
$result = mysqli_query($con,"SELECT fname, lname, user_id, phone FROM users WHERE `approved` = 0 AND `user_active` = 1 AND `declined` = 0");
while($row = mysqli_fetch_array($result)) {
echo '<div>' . $row['fname'] . ' ' . $row['lname'] . ' ' . '<a style="text-decoration:none;" href="../lookup/profile?' . $row['user_id'] . '">View Profile Here</a>' . ' ' . $row['phone'] . '</div>';
}
try this
$result = mysqli_query($con,"SELECT fname, lname, user_id, phone FROM users
WHERE `approved` = 0 AND `user_active` = 1 AND `declined` = 0 GROUP BY user_id");

I cannot figure out why this sql query isn't working and why it doesn't filter by the keyword coming from URL.
Here is my code:
include("menujednoty.php");
$hostname="localhost";
$username="kintrogorgo";
$password="password";
$keyword = $_GET['a.tovar'];
$db = "jednoty";
$dbh = new PDO("mysql:host=$hostname;dbname=$db", $username, $password);
foreach($dbh->query ('SELECT a.tovar ,
( select sum(b.kusy) from jednotypredaj as b where b.tovar=a.tovar and b.co="prijem" ) as prijem_ks,
( select sum(c.kusy) from jednotypredaj as c where c.tovar=a.tovar and c.co="predaj" ) as predaj_ks, kod
FROM jednotypredaj WHERE
(a.tovar LIKE '%$keyword%' ) as a GROUP BY a.tovar ORDER by a.tovar ASC') as $row)
{
echo "<tr>";
echo "<td>" . $row['tovar'] . "</td>";
echo "<td>" . $row['prijem_ks']. "</td>"; //Tu by mali bit predane kusy
echo "<td>" . $row['predaj_ks'] . "</td>";
echo "<td>" . $row['kod'] . "</td>";
echo "<td>" . ($row['predaj_ks']-$row['prijem_ks'] . "</td>");
echo "<td>" . (100/$row['prijem_ks']*$row['predaj_ks'] . "</td>");
echo '<td>Zobraziť</td>';
//echo '<td>In Development</td>';
//echo '<td>In Development 2</td>';
The quotes are breaking the SQL syntax, rewrite as a prepared statement to make it easier:
$stmt = $dbh->prepare('SELECT a.tovar ,
( select sum(b.kusy) from jednotypredaj as b
where b.tovar=a.tovar and b.co=:received ) as prijem_ks,
( select sum(c.kusy) from jednotypredaj as c
where c.tovar=a.tovar and c.co=:paid ) as predaj_ks, kod
FROM jednotypredaj WHERE
(a.tovar LIKE :keyword ) as a
GROUP BY a.tovar ORDER by a.tovar ASC');
$stmt->execute(array('received' => 'prijem','paid' => 'predaj','keyword' => $keyword));
foreach ($stmt as $row) {
echo "<tr>";
echo "<td>" . $row['tovar'] . "</td>";
...
Reconsider your SQL statement as you can either run correlated subqueries or conditional aggregates. Also, you table alias, a, was incorrectly positioned after WHERE clause:
Correlated subqueries (retains unit level records with kod column)
SELECT a.tovar,
(select sum(b.kusy) from jednotypredaj as b
where b.tovar=a.tovar and b.co='prijem') as prijem_ks,
(select sum(c.kusy) from jednotypredaj as c
where c.tovar=a.tovar and c.co='predaj') as predaj_ks,
a.kod
FROM jednotypredaj as a
WHERE (a.tovar LIKE '%$keyword%')
ORDER by a.tovar ASC
Conditional aggregates (group by aggregate records w/o kod unless added as a group)
SELECT a.tovar,
SUM(CASE WHEN a.co='prijem' THEN a.kusy ELSE NULL END) as prijem_ks,
SUM(CASE WHEN a.co='predaj' THEN a.kusy ELSE NULL END) as predaj_ks
FROM jednotypredaj as a
WHERE (a.tovar LIKE '%$keyword%')
GROUP BY a.tovar
ORDER by a.tovar ASC
MySQL may allow kod in SELECT clause and not in GROUP BY clause of aggregate query if your instance has the ONLY_FULL_GROUP_BY setting turned off but is not recommended and not ANSI-SQL compliant.
And as mentioned parameterize these queries in PHP script, binding string literals, that helps avoid quote handling and SQL injection.
I want to run an UPDATE query on a record after selecting it.
$db = JFactory::getDbo();
// Create a new query object.
$query = $db->getQuery(true);
$query
->select(array('p.*', 'u.id', 'u.name' ,'pr.*'))
->from($db->quoteName('#__chichi_photos', 'p'))
->join('LEFT', $db->quoteName('#__users', 'u') . ' ON (' . $db->quoteName('p.userID') . ' = ' . $db->quoteName('u.id') . ')')
->join('LEFT', $db->quoteName('#__chichi_profile', 'pr') . ' ON (' . $db->quoteName('pr.userID') . ' = ' . $db->quoteName('u.id') . ')')
->where($db->quoteName('p.id') .'=' . $photoID .'');
$db->setQuery($query);
$results = $db->loadRow();
I want to run an UPDATE query on a field in #__chichi_photos table that has an id in the result and if possible do it with a single query statement.
Basically what i want to do is update "hits" column on the field after it is selected. Thank You.
Im trying to rewrite mysql_ into mysqli_, but got 2 errors
mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given
and
mysqli_num_rows() expects parameter 1 to be mysqli_result,
why? Ive fixed mysql_query("SELECT...) into mysqli_query($db, "SELECT..) and all others
<?php
ob_start();
session_start();
include('config/configuration.php');
if($_POST['Login'])
{
$UserName=$_POST['username'];
$Password=md5($_POST['password']);
$UserQuery=mysqli_query($db, "SELECT Id, UserName, FirstName, LastName, Level FROM users WHERE UserName='$UserName' AND Password='$Password' AND IsActive=1 and level >= 3");
$UserDetails=mysqli_fetch_array($UserQuery);
if(mysqli_num_rows($UserQuery))
{
$_SESSION['UserName'] = $UserDetails['UserName'] . ' (' . $UserDetails['FirstName'] . ' ' . $UserDetails['LastName'] . ')';
$_SESSION['UserId'] = $UserDetails['Id'];
$_SESSION['Level'] = $UserDetails['Level'];
mysqli_query("UPDATE users SET NumberOfLogin = NumberOfLogin + 1, LastLoginDate = NOW() WHERE Id = " . $_SESSION['UserId'] . " ");
Your query is failing.
Try this to see the issue:
if (!$UserQuery) {
echo "MySQLi Error: " . mysqli_error($con);
die();
}
Here is my double-minded query:
$Quest = "SELECT * FROM TOAWorkorders";
$FindTechResult = mysql_query($Quest, $cxn)
or die ('The easter bunny is watching you' . mysql_error());
while ($row = mysql_fetch_array($FindTechResult))
{
if (strpos($BBT, 0, 3) != 'Sys')
{
$IdNum = $row['IdNum'];
$BBT = $row['BBT'];
$BBTArray = explode("-", $BBT);
$TechNum = $BBTArray["0"];
$Title = $BBTArray["2"];
$Name = explode(" ", $BBTArray['1']);
$FirstName = $Name["0"];
$LastName = $Name["1"];
}
echo $TechNum . ' !! ' . $FirstName . ' !! ' . $LastName . ' !! ' . $Title . '<br>';
$Quest = "UPDATE TOAWorkorders SET TechNum = '$TechNum', FirstName = '$FirstName', LastName = '$LastName', Title = '$Title' WHERE IdNum = '$IdNum'";
$result = mysql_query($Quest, $cxn) or die(mysql_error());
}
Everything works for about 2/3s of the database. That leaves 33,000 rows that are not updated. I cannot find any difference between the data that works and the data that doesn't.
Since you're doing an UPDATE, and you say the rest of the code works (meaning, I hope, that you get 109,112 echo'ed results), it must be that the ID isn't being found (WHERE IdNum = '$IdNum').
Try preceding that command with "SELECT COUNT(*) from TOAWorkorders WHERE IdNum = '$IdNum'" and see if you get 33,000 zeros when the program runs. If you do, then you have missing IdNum values in your table.
If you don't, please provide details and I'll let you know.
I am asking this question on behalf of a small group of my users that have this problem.
Once the script they are using gets to the 21st ID, it generates the following error:
The SELECT would examine more than
MAX_JOIN_SIZE rows; check your WHERE
and use SET SQL_BIG_SELECTS=1 or SET
SQL_MAX_JOIN_SIZE=# if the SELECT is
okay
I have researched this as much as possible and found something of an answer : http://dev.mysql.com/doc/refman/5.0/en/set-option.html
The problem is that they are on shared hosting so they cannot change their MySQL settings to fix the errors.
Is there anything I can write into my script so that they do not have this problem?
This is the function that generates the database query based on which modules are loaded:
$sql = 'SELECT a.id as id , a.address as address';
$query = 'SELECT'
. ' name AS module_name'
. ', databasename AS module_database'
. ', pregmatch AS module_pregmatch'
. ', pregmatch2 AS module_pregmatch2'
. ', html AS module_html'
. ', sqlselect AS database_sqlselect'
. ', sqljoin AS database_sqljoin'
. ', sqlupdatewithvalue AS database_sqlupdatewithvalue'
. ', sqlupdatenovalue AS database_sqlupdatenovalue'
. ' FROM #__aqsgmeta_modules'
. ' WHERE enabled = 1'
. ' ORDER BY id';
$db->setQuery($query);
$results = $db->loadObjectList();
if (count($results) != 0) {
foreach ($results as $result) {
$sqlselect .= ', ';
$sqlselect .= $result->database_sqlselect;
$sqljoin .= ' ';
$result->database_sqljoin = preg_replace('/\{DATABASENAME\}/Ui', $result->module_database, $result->database_sqljoin);
if (!(preg_match("/" . $result->database_sqljoin . "/Ui", $sqljoin)))
$sqljoin .= $result->database_sqljoin;
}
}
if ($use_sh404sef)
$sqlselect .= ', g.oldurl AS sefurl';
$sql .= $sqlselect;
$sql .= ' FROM #__aqsgmeta_address AS a';
$sql .= $sqljoin;
if ($use_sh404sef)
$sql .= ' LEFT JOIN #__redirection AS g ON g.newurl = a.address';
$sql .=
//. ' WHERE a.id IN (' . $cids . ')'
' WHERE a.id = ' . $id
. ' ORDER BY a.address asc,a.id '
;
$db->setQuery($sql);
$rows = $db->loadObjectList();
MAX_JOIN_SIZE is a safety catch commonly used on the shared hostings.
It won't let you accidentally run long queries which would hang the server.
Issue this command:
SET SQL_BIG_SELECTS = 1
before running the query you know to return lots of values.
The MAX_JOIN_SIZE gets hit when MySQL calculates the Cartesian product of a join, not the actual expected records back. Therefore, if you're joining a massive table to another massive table, this will creep up. Use indexes and views to pare down the possible table hits if it's really that large.
