Good Evening - I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP. It works on a different part of the site within the admin panel but not here. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out...

// CATEGORIES

$query = "SELECT * FROM cat";
$result = mysql_query($query);

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

$catid = $row['id'];
$catname = $row['name'];

$output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\">
<a href=\"product.php?cat=$catid\">
<span>$catname</span>
</a>\n";

$querynav = "SELECT * FROM subcat WHERE pid = '$catid'";
$resultnav = mysql_query($querynav);

while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC))
{

$subcatid = $row['id'];
$subcatname = $row['name'];

$output .= "<ul class=\"level0\">
<li class=\"level1 nav-2-1 first\">
<a href=\"product.php?cat=$catid&subid=$subcatid\">
<span>$subcatname</span>
</a>
</li>
</ul>
</li>";
}

}

Loop Inside A Loop

So I have a PHP parent page that is accesses that scans the database for the passed token in the URL and then replaces content on the template page using a loop. My issue is that I am trying to use a loop on the secondary page which causes the white screen of death. From what I can tell the loop inside a loop is causing the issue.
I'll paste the code below, let a newbie know if you have any ideas or can point me in the right direction.

Thanks everyone!

Here is the chunk of code from the parent page with the loop function....

// output pre content
eval("\$preContent = \"$preContent\";");
print_r( replaceChar($preContent) );

$sqlSearch = "SELECT * FROM ".$row[tdbd_name]." WHERE ".$sqlKeyword." LIMIT ".MAX_ROWS;
$resultSearch = mysql_query($sqlSearch);

while($displayrows = mysql_fetch_assoc($resultSearch)) {
   $display = replaceTokens($loopTemplate);
   $display = str_replace('\\', '[backslash]', $display);
   $display = str_replace('[%', '$displayrows[', $display);
   $display = addslashes(str_replace('%]', ']', $display));
   $display = replaceTokens($display);
   $display = changeCase($display);

   eval("\$display = \"$display\";");

   $display = stripslashes($display);
   $display = str_replace('[backslash]', '\\', $display);
   $display = replaceChar($display);

   print_r( $display );

}
// output post content

And here is the loop function from the page that the above code loops through replacing tokens in.

<?php
$mySQLServer = "xxxxxxxxx";
$mySQLUser = "xxxxxxxxxx";
$mySQLPass = "xxxxxxxx";
$mySQLDB = "xxxxxxxxxxxxx";
$SQLToday = date("m/d/y") . "<br />";
$SQLsevendays = mktime(0,0,0,date("n"),date("j")-7,date("Y"));
$SQLsevenname = (date("l", $SQLsevendays));
$SQLsevennumber = (date("jS", $SQLsevendays));
$dbhandle = mssql_connect($mySQLServer, $mySQLUser, $mySQLPass)
or die("Couldn't connect to SQL Server on $myServer");
$selected = mssql_select_db($mySQLDB, $dbhandle)
or die("Couldn't open database $myDB");
$query = "WEB_ApproveHistory @State='CA', @Days=5, @Records=8";
$data = mssql_query($query);
$result = array();

while ($row = mssql_fetch_object($data))
{
$result[] = $row;
$returnedresults = (97*($row->TotalApprovals)) ;
}

$englishreturnedresults = number_format($returnedresults);
echo 'In just the last week since ' . $SQLsevenname . ' the ' . $SQLsevennumber . ' has delivered ';
echo $englishreturnedresults;
echo ' Here are just a few people ';

echo '<ul class="BulletCheck">';

mssql_next_result($data);

while ($row = mssql_fetch_object($data))
{
$result[] = $row;
echo '<li>' . ' ' . $row->FirstName . ' From '. $row->City . ', ' . $row->State .' PreApproved On ' .$row->ApprovedDate . '</li>';
}

mssql_close($dbhandle);
?>

I attach the image of result from this code

But the output that I want is all LOT_CODE with P35 PCODE will only display below P35
and all LOTCODE with P35M PCODE will only display below P35M.

Thank you

I hope somebody can help me..

Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically. With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table. As you can see at the above part the script prints the following:

                    Array ( [0] => 542 )

                    Array ( [0] => 543 )

                    Array ( [0] => 544 )

And I am looking to insert into the column of the table the following:

542, 543, 544

I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now. Any suggestions on how to do this?

Deleting Inside A Loop

I've seen two post now about not deleting within a loop and I think I may need to ask a question about this.

I have a photograph db that gives the addresses of the thumbs and photos in files for a product, it also is keyed to the products db. There can be more than one photo per product.

If someone selects yes from a radio button and clicks submit the process should delete the record of the product in the product db, delete the photos in the photo images/files(this is the loop) and then delete the product id and row in the photo db

Is this a decent way of doing this?

if ($_POST['sure'] == 'Yes') { // If Yes delete the item and its pictures in image folders

$q = "DELETE FROM product WHERE id = $item LIMIT 1"; // Delete the product record
$r = @mysqli_query ($dbc, $q);

$q = "SELECT id, thumb, photo FROM photos WHERE id = '$item'";
$r = @mysqli_query ($dbc, $q);
if ($r){
while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)){
unlink('images/members/'.$row['thumb'].''); // Remove-delete photos from folders for each row in photo db
unlink('images/members/'.$row['photo'].'');
}
}

$q = "DELETE FROM photos WHERE id_prod = $item"; // Delete the photo record
$r = @mysqli_query ($dbc, $q);

// When through redirect
header("Location: $home/member/index.php?user=$mem_id");
exit();
}

If Statement Inside Of A While Loop

After it goes through the while loop its supposed to take the ID of the first one in the loop and find out its awardType and then with the awardType variable go through the the if statement. After it displays it the code that fits the awardType variable then it gets the second item in the while loop and then with the ID of the second item takes it back to get the awardType and then goes back through the if statement again.

the confusing part for me is that the queries are connecting to 2 different tables for data.. and both need to be found for the div to be echo.

if($item['quantity'] >= 1){
if($item2['type'] == 'weapon'){

code below....

Code: [Select]

<div class="g_content"><h3 style="text-align: left">  Weapons</h3><div class="g_text">
<table align='center' cellspacing='10'>
<?php

$current_col = 1;
$max_col = 4;

$query = $db->execute("select * from items where `player_id`=?", array($player->id));

while($item = $query->fetchrow())
{
$query2 = $db->execute("select * from `blueprint_items` where `id`=?",array($item['item_id']));
$item2 = $query2->fetchrow();

//DISPLAY IF QUANTITY IS 1 OR MORE.
if($item['quantity'] >= 1){
if($item2['type'] == 'weapon'){
    //Open new row if first column
    if($current_col==1)
    {
        echo "<tr>\n";
    }

    //Display current record

    echo "<td width='25%'>";
echo "<center><img src=\"{$item2['img']}\" width='80' height='80' style=\"border: 1px solid #CC9900\"></center>";
    echo "<center><a href=\"../description.php?id={$item2['id']}\">{$item2['name']}</a> [x".$english_format_number = number_format($item['quantity'])."]</center>";
    echo "<center>$".$english_format_number = number_format($item2['value'])."</center>";
echo "<center>[<a href='../item.php?sell=".$item['id']."'>Sell</a>] [<a href='../item.php?market=".$item['id']."'>Market</a>] <br>[<a href='../item.php?send=".$item['id']."'>Send</a>] [<a href='../item.php?equip=".$item['id']."'>Equip</a>]</center><br>";
    echo "</td>\n";
//Close row if last column
    if($current_col==$max_col)
    {
        echo "<tr>\n";
        $current_col = 0;  //<---Changed
    }
    $current_col++;
}
}

}
//Close last row if needed
if ($current_col!=1)
{
    for(; $current_col<=$max_col; $current_col++)
    {
        echo "<td> </td>\n";
    }
}

?>

While Loops Inside A While Loop??

Hi there,

Having an issue here. I have a site where you can join a group. When the user goes to the groups page it will list their groups that they have joined. This is fine. I also want to be able to show how many other members are in that group and am getting stuck. $row group_name works ok but not sure how to start by adding another while loop in for the members.

The table consists of group id, group name, member id (L_ID) and member name

$result = mysql_query("SELECT * FROM groups2 WHERE L_ID = ". $_SESSION['member_ID'] .";");

while ( $row = mysql_fetch_array($result) ) {
echo("<tr>
<td><font face='Arial, Helvetica, sans-serif' size='3'><strong>" . $row["group_name"] . "</strong></font></td>
</tr><tr>
<td><font face='Arial, Helvetica, sans-serif' size='1' color='#0000FF'><strong>Members ("???")</strong></font></td>
</tr><tr>
<td><hr width=95%><br></td>
</tr>");
}

Hey. So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

'2014-02-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

)
)
);

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each. And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested. This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance. In short my question is, are there any better methods of handling this with the data setup we currently have?

Exec() Inside Loop Does Not Work?

This code works outside of the while, but not inside

while ($row = mysql_fetch_assoc($res)) {

  $cmd = exec("mysql -h$host -e \"show status like 'wsrep_cluster_size'\"");
  echo $cmd;
}

I have found nothing on google, stackoverflow or the php manual that explains why this does not appear to work inside a loop?

Why Insert Fail When I Put An If Inside A For Loop ?

Hi - I have spent 2 days trying to figure this out. I must be doing something stupid ...

I am trying to update the DB with a collection of variables off of a various POST array's. I have indexed the variables so that I can loop through them with a FOR.

However I am having all kinds of trouble:

1 - WEIGHT is giving 5 values even though the counter should only go 4 times.
2 - The WEIGHT variable is going into the wrong field in the DB even though I specify in my Query a specific place.
3 - I get undefined offset errors even though I have initialised the variables with their respective offsets.
4 - Adding the conditional statement adds even more offset errors even though they are initialised

I am starting to wonder if my entire approach to updating my DB is flawed.

As a student of PHP I think I need someone with more experience to look at what I am doing and tell me if something jumps out at them.

There is a lot of statements echoing out values - and they all seem to check out.

Man Many thanks for your advice

function finishedorder(){
$prodname = $_POST['prodname'];
$prodid =$_POST['prodid'];
$quantity = $_POST['quantity'];

$orderid = $_POST['orderid'];

Questions About A Function Inside A While Loop...

I'm using this line a lot on my site. It would be nice if I didn't have to change it 10 times over when I decide to change something. Can I wrap that into a Function and use it in a While loop?

echo '<div><a href="/tag/'. strtolower($nameFirst) . '-' . strtolower($nameLast) .'">'. $nameFirst . ' ' . $nameLast .'</a>, ';

I have this above it in the While loop.

$nameFirst = $row['nameFirst'];
$nameLast = $row['nameLast'];

My function predictably looks like this...

function player_name () {

echo '<div><a href="/tag/'. strtolower($nameFirst) . '-' . strtolower($nameLast) .'">'. $nameFirst . ' ' . $nameLast .'</a>, ';
