I'm currently adding fileID to idarray[] and then do a foreach. But in addition to fileID I also need serverID and id in the array and the foreach, how do I do this? So basically I need to find out how to add 2 more values to the array and then also use those extra values in the foreach.
$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
$idarray[] = $row['fileID'];
}
foreach ($idarray as $value)
{
$result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$value AND removed=0 AND serverID=$XXXserverIDhereXXX");
while($row = mysql_fetch_array($result))
{
$sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
mysql_query($sql) or die(mysql_error());
}
}
Why not just store the whole row into an array?
$rowarray[] = array();
$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
$rowarray[] = $row;
}
foreach ($rowarray as $row)
{
$fileid = $row['fileID'];
$serverid = $row['serverID'];
$result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$fileid AND removed=0 AND serverID=$serverid");
while($row = mysql_fetch_array($result))
{
$sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
mysql_query($sql) or die(mysql_error());
}
}
But really, your whole code piece here is a mess. You can accomplish this way more efficiently using JOINs.

This is the entire code the error must be in query 3 or 4. As you can see query 3 just gets info to build query 4 which should return the results.
I've got query 1 & 2 working ok which have the correct data showing.
<?php
session_start();
//printf('<pre>%s</pre>', print_r($_SESSION, true));
require('includes/config.inc.php');
require('includes/session.php');

$query = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'product' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result = mysql_query( $query) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
$hash = $row['hash'];
$foreignid = $row['foreign_id'];
$qty = $row['cnt'];
}
$query2 = "SELECT * FROM food_delivery_products WHERE food_delivery_products.id = ".$foreignid."";
$result2 = mysql_query( $query2) or die(mysql_error());
while($row = mysql_fetch_array($result2))
{
$name = $row['name'];
$description = $row['description'];
}
//---------------------------------------------------------------------------------------------------------------
$query3 = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'extra' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result3 = mysql_query( $query3)or die(mysql_error()) ;
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
}
$query4 = "SELECT * FROM food_delivery_extras WHERE food_delivery_extras.id = ".$foreignidextra."";
$result4 = mysql_query( $query4) or die(mysql_error());
while($row = mysql_fetch_array($result4))
{
$nameextra = $row['name'];
}
echo $nameextra;
echo $qtyextra;
DB_Disconnect();
//$products = implode(", ",$_SESSION['pdf_quote']['product_arr']);;
//print $products
?>
print $row; is only valid inside the loop if you want to print all of them. Otherwise it will print only the last $row. Make it
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
print $row;
}
its because you are printing the $row after the while loop gets executed
So it only prints the final result set
Use something like this instead:
$query3 = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'extra' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result3 = mysql_query( $query3) ;
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
print_r($row);
}
you can also use the var_dump($row); instead of print_r($row);
this will output all the values stored in the $row array each time the loop iterates
I want to make a Navigation with 2 levels.
My Code so far
<?php
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='' ORDER BY name");
$result = mysql_query($sql);
$list = array();
while ($row = mysql_fetch_assoc($result)) {
$list[] = $row;
}
foreach ($list as $kat) {
echo '<li>' . $kat['name'] . '</li>';
}
?>
Nested Sets are at the moment too tricky for me.
I want at the end this.
<li>$kat['name']
<li>$kat['name'] from PID</li>
</li>
MySQL:

No I want to get the things our of the MySQL DB see the image Link.
MySQL:
id—–pid——name
1——0——–name1
2——0——–name2
3——0——–name3
4——3——–name3.1
5——3——–name3.2
<?php
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='' ORDER BY name");
$result = mysql_query($sql);
$list = array();
while ($row = mysql_fetch_assoc($result)) {
$list[$row['id']] = $row;
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='".$row['id']."' ORDER BY name");
$res = mysql_query($sql);
while($rw = mysql_fetch_assoc($res)){
$list[$row['id']]['sub'][] = $rw;
}
}
echo "<pre>";
print_r($list);
?>
I need to do a search in each $row2 variable, so i could find if there is columns that are not equal to $row1 column.
This is what I tried,
$result1 = mysql_query('SELECT gpu FROM ng2s3_content');
$result2 = mysql_query("SELECT gpu FROM bigc3_gpu");
while ($row1 = mysql_fetch_array($result1)) {
while ($row2 = mysql_fetch_array($result2)) {
foreach ($row2 as $ar) {
if ($ar == $row1[0]) {
}
else {
echo $ar;
}
}
}
}
looks like you want distinct values from your database ,
use mysql query , that will return a resource with distinct values ,
$result = mysql_query('SELECT gpu FROM ng2s3_content UNION SELECT gpu FROM bigc3_gpu');
while ($row = mysql_fetch_array($result)) {
echo $row['gpu'];
}
The query I have below will only show me one result even if there are multiple matching entries (completely or partially matching). How do I fix it so it will return all matching entries:
//$allowed is a variable from database.
$sql = "SELECT `users`.`full_name`, `taglines`.`name`, `users`.`user_id` FROM
`users` LEFT JOIN `taglines` ON `users`.`user_id` = `taglines`.`person_id`
WHERE ( `users`.`user_settings` = '$allowed' ) and ( `users`.`full_name`
LIKE '%$q%' ) LIMIT $startrow, 15";
$result = mysql_query($sql);
$query = mysql_query($sql) or die ("Error: ".mysql_error());
$num_rows1 = mysql_num_rows($result);
if ($result == "")
{
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if($rows == 0)
{
}
elseif($rows > 0)
{
while($row = mysql_fetch_array($query))
{
$person = htmlspecialchars($row['full_name']);
}
}
}
print $person;
Because your overwriting $person on each iteration.
Hold it in a $person[] array if your expecting more then one. Then loop through it with a foreach loop when you intend to output.
Not related but your also querying twice, you only need 1 $result = mysql_query($sql);
Update (Simple Outputting Example):
<?php
$person=array();
while($row = mysql_fetch_array($query)){
$person[] = array('full_name'=>$row['full_name'],
'email'=>$row['email'],
'somthing_else1'=>$row['some_other_column']);
}
//Then when you want to output:
foreach($person as $value){
echo '<p>Name:'.htmlentities($value['full_name']).'</p>';
echo '<p>Eamil:'.htmlentities($value['email']).'</p>';
echo '<p>FooBar:'.htmlentities($value['somthing_else1']).'</p>';
}
?>
Or an alternative way to is to build your output within the loop using concatenation.
<?php
$person='';
while($row = mysql_fetch_array($query)){
$person .= '<p>Name:'.$row['full_name'].'</p>';
$person .= '<p>Email:'.$row['email'].'</p>';
}
echo $person;
?>
Or just echo it.
<?php
while($row = mysql_fetch_array($query)){
echo '<p>Name:'.$row['full_name'].'</p>';
echo '<p>Email:'.$row['email'].'</p>';
}
?>
$sql = "SELECT * FROM table";
$result = mysql_query($sql);
while($row = mysql_fetch_row($result)){
// PRINT COLUMN NAMES WITH EMPTY VALUE
}
how can i do this?
thanks
$sql = "SELECT * FROM table";
$result = mysql_query($sql);
while($row = mysql_fetch_assoc($result))
{
foreach ($row as $columnName => $value)
{
if (empty($value))
{
echo $columnName;
}
}
}
