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'),
'2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),
'2014-01-03' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),
'2014-01-04' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

),
'row2' => array(
'dates' => array(
'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?

Calculation Displays Correct Answer In Foreach Loop But Not In While Loop. Why?

Below is my output on the browser:

Student: Kevin Smith (u0867587)
Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
Year: 3

Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B

Session: AAB Session Mark: 72 Session Weight Contribution 20%

Session: AAE Session Mark: 67 Session Weight Contribution 40%

Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B

Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.

Below is the code:

Code: [Select]
$sessionMark = 0;
$sessionWeight = 0;
$courseMark = 0;

$output = "";

$studentId = false;
$courseId = false;
$moduleId = false;

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

$sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
$sessionWeight += ($row['SessionWeight']);
$courseMark = ($sessionMark / $sessionWeight * 100);

if($studentId != $row['StudentUsername'])
{

//Student has changed
$studentId = $row['StudentUsername'];

$output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";

}

if($courseId != $row['CourseId'])
{

//Course has changed
$courseId = $row['CourseId'];

$output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n";

}

if($moduleId != $row['ModuleId'])
{

//Module has changed
if(isset($sessionsAry)) //Don't run function for first record
{

//Get output for last module and sessions
$output .= outputModule($moduleId, $moduleName, $sessionsAry);
}

//Reset sessions data array and Set values for new module

$sessionsAry = array();
$moduleId = $row['ModuleId'];
$moduleName = $row['ModuleName'];
}

//Add session data to array for current module

$sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);

} //Get output for last module

$output .= outputModule($moduleId, $moduleName, $sessionsAry);

//Display the output
echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Hey guys,

Got another question im hoping someone can help me with.

I have a foreach loop (for use in a mysql query):

   foreach ($interests as $interest) {
     $query .= "($id, $interest), ";
   }

problem is i do not want the comma(,) in the last loop.

Is there some kinda of function i can use so it does not insert it on last loop?

Or should i just use a for loop with a nested if loop? something like ;

   for($i=0; $i < count($interests); $i++){
      $query .=
      "($id, '$interests[$i]')";
      if($i + 1 < count($interests)) {
         $query .= ", ";
      }
      }

Cheers guys

For Loop & While Loop Working, But Results Are Wrong In Both

I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong!

The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match)

The if loop displays ALL listings with the same name (counts them all) so there are no unique listings!

<?php

$posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'";
$posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!");

/* While Loop */
while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
}

/* For Loop */
$posts_by_city_row = mysqli_fetch_array($posts_by_city_results);

for ($i=0; $i<sizeof($posts_by_city_row); $i++) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
}

?>

Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below):

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>';

I'm having a really bad brain fart and I cannot get the logic correct here lol.

I need divs wrapped around every set of 5 images so if there is a total of 8 images then there would be 2 sets of divs (first with 5 images, second with 3 images) and if there was 12 images then there would be 3 sets of divs (first two with five images, last one with 2 images) etc etc What am I doing wrong and is there an easier way to do this?

A While Loop In A For Loop Problem

A WHILE loop in a FOR loop problem

Script about links and sublinks from 1 table.

In fact 2 questions about that.
1) In the FOR loop I have for example to do the loop 3 times. (needs to find 3 results withing the loop with if and else)
When first time, he's gonna search within the WHILE loop that holds (for example) 10 records of the DB in a variable.
He needs to search for rowid number 5, he found it
He goes out of the WHILE loop and goes searching again but now for rowid number 2

Now it seem that the WHILE loop start searching for number 2 but won't start from his first row in the variable (10 rows from the db ).
He start at row number 6 instead of beginning all over again !!!

-> so the order of the numbers of rows MUST be in an ascending order, ortherwise he won't find them all ! But the numbers I have are NOT in an ascending order !!!
Why doesn't the WHILE loop begin again from his row 1 in the variable ?

FOR loop
{
WHILE loop { content here, break; }
}

2) even when I get all the result in an ascending order, he won't go doing a second search but with a different rowid number that he gets from the FOR loop.
It is giving me back indeed the right new rowid number, but the WHILE loop is doing nothing.
I have put many echo "..."; and other stuff for checking but can't find the cause !

Here's the code :

Code: [Select]
// $ResultShow = 10 rows from mysql db
if(isset($ResultShow)){

if (mysql_num_rows($ResultShow) >= 1){

//$linksuborder = "2,3,4";
$array1 = explode(",", $linksuborder);
sort($array1);

for ($n = 0; $n < count($array1); $n++){ // searchin for the right row id in the variable $ResultShow where we find the numbers for next loop
$r1 = each($array1);

While($Row2 = mysql_fetch_array($ResultShow)) {

if($Row2["linkid"] == $r1['value']) // found it, now look for the numbers that we'll put in an array
{ echo "---here the content---";

// linksuborder is where numbers from row id's are stored like 5,2,8
//now put them in an array
$array2 = explode(",", $Row2["linksuborder"]);
sort($array2);

for ($n2 = 0; $n2 < count($array2); $n2++){
$r2 = each($array2);

////// here searching for the sublinks //////
While ($Row3 = mysql_fetch_array($ResultShow))
{
if($Row3["linkid"] == $r2['value']) // search for the right row id within the variable $ResultShow
{
echo "---here the content---";
break; // found it, so no need to do the rest of the loop

} // end if
} //end while
////// end searching for sublinks //////

} // end for
} // end if

else
{
echo "--- content here ---";
}

} // end while
} // end for

} //end if
} // end if

Table :

linkid linksuborder linktitle
1 2,3,4
2 9,7,8 mainlink1
3 10 mainlink2
4 mainlink3
5
6
7 sublink3
8 sublink2
9 sublink1
10 sublink4

-> linksuborder 2,3,4 are the row id's for the mainlink
-> than we put the numbers 9,8,7 (also row id's) mentioned in row linkid 2 also in a new array
-> now we can search for the sublinks
-> get the details from row linkid 9, than 7, than 8

-> First mainlink is compleet, now go to row linkid 3 to do it all over again for the next mainlink...

Evening everyone.

1st of all here is my code

<?php
include('connect.php');
$query = mysql_query("SELECT * FROM cats");
while($row = mysql_fetch_assoc($query)){

$catid = $row['catid'];
$catname = $row['cname'];

$query1 = mysql_query("SELECT * FROM subc WHERE catid = $catid");
while($row = mysql_fetch_assoc($query1)){

$subid = $row['sid'];
$sname = $row['sname'];

?>

<li class="top"><a href="javascript:ajaxpage('view.php?catid=<?php echo $catid;?>', 'content');" class="top_link" title="<?php echo $catname;?>"><span><?php echo catname;?></span></a></li>
<ul class="sub">
<li><a href="view.php?catid=<?php echo $catid;?>&subid=<?php echo $subid;?>"><?php echo $sname;?></a></li>
</ul>
</li>

<?php
}}
?>

</ul>
</div>

I have two tables, cats and subc, cats contain fields catid and catname, subc contains catid, sid, and sname

What I am trying to do is echo the results to build my menu.

However, for instance catid 1 is electronics and contains 5 sub cats, but the script is echoing 5x electronic top menus and no sub menus (the 5 sid's that match the catid)

I hope someone understands what I am trying to say!

Can any point out what I am doing wrong?

Cheers

I need to send some of the data to my php file via flash. Below in my php file I'm trying to use a for-loop to convert all the variables to php variables to prevent sql injection. How effective is this method? Please help me with your valuable ideas.

Thank you.

<?php
$conn = mysql_connect("localhost","my_un","my_pw");
mysql_select_db("my_db");

foreach ($_POST as $key => $value) {
$$key = $value;
$$key = mysql_real_escape_string($$key); }

$result = mysql_query("SELECT * FROM my_db2 WHERE username = '$username'");

if (mysql_num_rows ($result) > 0){
$register = "Retry.";
echo($register);
} else {
mysql_query("INSERT INTO my_db3 (username, password, surname, firstname, company) VALUES ('$username', '$password', '$surname', '$firstname', '$company')");
$register = "Successful.";
echo($register);
}
?>

Hi,
I am trying to create a loop as such so that when I load the script it will check for the date in the 'start_date' field, normally formatted by the date(Y-M-D) function, but I need it to loop until the end of the current year and insert data too.
Please Advise,

I am trying to populate different select boxes from a DB lookup...
I look in two table.... One to the catid and then all subcats per catid...
I am not sure how this should work... My code as follow:
Code: [Select]
$catkey='1,4,5';
$query = "SELECT
adcat.id AS catid, adsubcat.name AS subname, adsubcat.id AS subid, adsubcat.linkname AS sublink,
adcat.clinkname AS clink, adcat.name AS catname
FROM adsubcat
JOIN adcat ON adcat.id=adsubcat.catid
WHERE adsubcat.catid IN($catkey) ORDER BY adsubcat.name ASC";
$result = mysql_query($query) or die(mysql_error());
$num_rows = mysql_num_rows($result);
while ($row = mysql_fetch_assoc($result)){
$catid=$row['catid'];
$subid=$row['subid'];
$subname=$row['subname'];
////////////////////////////////////////////////////////////////////////////// STUFF I AM NOT SURE OF STARTS HERE
// The loop should now echo at the start of every echo $catname.'<select id="subcat" multiple="multiple" name="sub[]"><option value="" >ALL SUB-CATEGORIES</option>';
////And for every subcat per id it should echo '<option value="'.$subid.'">'.$subname.'</option>';
///// The loop per Catid should end with echo '<select>';
////////////////////////////////////////////////////////////////////////////// STUFF I AM NOT SURE OF ENDS HERE
}

I want it then to print out as follow:
CAT 1
<select id="catid1" multiple="multiple" name="cat1[]">
<option value="0" >ALL SUB-CATEGORIES FOR Cat 1</option>
<option value="1" >Subname 1.1</option>
<option value="2" >Subname 1.2</option>
</select>

CAT 4
<select id="catid4" multiple="multiple" name="cat4[]">
<option value="0" >ALL SUB-CATEGORIES FOR Cat 4</option>
<option value="4" >Subname 2.4</option>
<option value="7" >Subname 2.7</option>
</select>

CAT 5
<select id="catid5" multiple="multiple" name="cat5[]">
<option value="0" >ALL SUB-CATEGORIES FOR Cat 5</option>
<option value="65" >Subname 5.65</option>
<option value="34" >Subname 5.34</option>
</select>
